exterior paint durability Construction relations

1 exterior paint durability1.1 weatherability and color retentionDecorative function is one of the important features of the exterior paint. Cultured Stone Veneer Exterior paint is long-term exposure to the outdoors, by the wind, rain and sun, after a period of time, the appearance of finishes chalking, discoloration, discoloration, loss of light and other phenomena. The weathering of high-performance exterior paint color retention requirements generally 8 ~ 10a, the equivalent of a national standard artificial accelerated aging 1000h, and its color is not greater than 2. Coating chalking, fading and discoloration and coating binders and pigments are closely linked.(A) Binders and weatherability and color retentionThe base material plays a decisive role in the performance of the paint. External finishes by ultraviolet light, the sun and the rain will progressively deterioration, which ultraviolet impact. It enables the base polymer chemical reaction and deterioration. If the emulsion polymer containing a polyethylene, polyacrylate, polymethacrylate, polystyrene, polyvinyl chloride, poly (vinyl acetate) and poly-butadiene, etc., by ultraviolet radiation, it is prone to the main chain scission, intermolecular cross linking or degradation reactions.So that the binder polymer for crosslinking or degradation will cause changes in coating properties: intermolecular crosslinking makes extended reduced, while the main chain will reduce the strength of the coating, eventually leading to the yellowing of the exterior paint or powder technology. Note that the base material in the preparation of high performance exterior paint should preferably therefore, select the excellent weathering resistance of the emulsion as a binder. Silicone modified acrylic emulsion and water emulsion polyurethane is the fastest growing and the most the coating binders variety of development prospects. Higher chemical bonds between the polymer molecules of these binders and special molecular structure determines they have excellent anti-aging properties, its artificial accelerated aging more than 1500h, some even up to 3000h, fully able to meet the high-performance exterior paint on Binders weatherability requirements. Of course, the emulsion weather resistance not only concerned with the varieties And it is also the size of the emulsion particles in the emulsion and emulsifying system closely related. Emulsion finer particles, the coating film formed by the more perfect, the more excellent weather resistance corresponding. Furthermore, still in the emulsion by adding a certain amount of an ultraviolet absorber, can reduce the UV damage of the coating film.(2) pigments and weathering protection colorPaint coating by the base material polymer and the Yen (fill) material. Therefore, the types and ratio of the two kinds of main component determines the structure and physical properties of the coating film. In the coating formulation, when the pigment volume concentration (PVC) is below the critical PVC, pigment particles dispersed in the base polymer continuous phase to form the "sea - island" structure; but if the PVC exceeds the critical PVC base polymers the gaps between the pigment particles can not be completely filled with loose accumulation of pigment particles, voids therebetween, the coating scrub resistance, contamination resistance, weatherability, a sharp decline. Similar emulsion varieties, PVC is lower, the higher the gloss, weathering resistance, color retention worse. So, in the preparation of high performance exterior paint should strictly control PVC less than the critical PVC as far as possible, to ensure the integrity of the coating.The primary role of the pigment is to make the coating film has a certain degree of opacity and show different colors, so to make the coating film has excellent weather resistance, a pigment on the need to have good hiding power and coloring power, the higher the degree of dispersion, sharp The color and light stability. The white pigment excellent weather resistance, not only their own color consistent, and can absorb large amounts of ultraviolet light, to mitigate the damaging effects of ultraviolet radiation on the base material or other color pigments that improve weatherability of the coating color retention. White pigment, the most widely used, and the best of rutile titanium dioxide. Color pigments, inorganic and organic pigments are used, but the coating film weathering performance considerations, the general use of inorganic pigment is more suitable. The light resistance and weather resistance of the inorganic pigments are generally superior to organic pigments, present in the exterior latex paint, the main use of the excellent weathering resistance of the iron-based pigment.In addition, in the high-performance coated should avoid using easy powder filler, and filler has better weather and pH stability. Better application precipitated barium sulfate, quartz powder, mica and wollastonite powder.2.2 stain resistanceChina's industrial smoke, excessive dust and vehicle exhaust emissions, high dust content in the air, and less per capita green area. Therefore, high stain resistance exterior paint adapt to this special state of the environment is extremely important practical significance.High stain resistance performance of the exterior paint is very important. Exterior paint slowly, an important reason for this is the stain resistance of the coating is not ideal, the decorative effect is short-lived. Therefore, the need to address an important issue for the high-performance exterior paint is to try to improve the coating anti-stain resistance coating of contaminated medium resilience. Coating anti-contamination and poor performance of the main reasons are: ① the coating preparation process generally required the use of emulsifiers and a variety of additives, with the passage of time, in the coating of these low molecular weight substances to be volatilized, so that the coating left in a large number of pores. The microstructure, compared with solvent-based paints, latex paints and coatings containing a large number of micropores, and the surface is relatively rough, exhibit uneven. Atmospheric dust is easily deposited under the effect of gravity which, to different degrees of covering of the coating color. When it rains, the dust along with the rain capillary action penetrated coating, evaporation of water, dust particles continue to be retained in the pores, "fatal" impact this will have on the decorative effect of the coating.Therefore, increasing the density of the coating, hard is an important way to address contamination issues. I have developed a sol-acrylate emulsion organic-inorganic composite coatings, anti-stain determination, its reflectance decreased only about 5%, mainly due to the sol colloidal particles are relatively subtle, the particle size is generally 5 ~ 40nm, the structure after the film formation is very compact and hard, the gap is minimal, dust particles easily penetrated therebetween. Add nanoscale SiO paint can improve the hardness of the coating to dramatically improve the ability of anti-staining. ② binder, the organic polymer chain structure determines the polymer emulsion coating prone to the accumulation of static electricity, thereby generating the electrostatic adsorption, dust particles are easily adsorbed at the surface of the coating, the decorative effect of the coating, the emulsion polymer chain covalent bond (e.g. Si-O) of the introduction of some of the ionic inorganic conductive properties, can be improved to avoid electrostatic adsorption pollution of the coating. ③ Since the coating high temperature return YS, easy, dust, resulting decorative effect decreased, generally high hardness coating stain resistance, which requires a high glass transition temperature (Tg) of the emulsion, but the coating film at the same time constructability disadvantage. Cultured Stone VeneerStrictly speaking, the paint just a semi-final purpose coating on the surfaces of buildings, buildings from the decorative and protective role. Therefore, the dry film coating after construction is finished. Coating durability play supporting construction technology have a close relationship, in order to obtain a satisfactory long-term effects of finishing, it is necessary to strictly control the construction engineering quality of the paint.Usually due mainly out powder coating defects caused by improper construction methods of exterior paint, peeling, efflorescence, shedding. In order to avoid the emergence of these quality defects, should be strictly in accordance with the the coating construction engineering specifications for construction. For cement grassroots should pay special attention to control moisture and alkalinity. Accordance with the regulations applying emulsion paint, the moisture content shall not be greater than 10%; concrete base material curing period should be more than 28d, cement mortar plastering should be more than 14d, grassroots pH control in less than l0; surface should be cleared before construction dust, oil, etc., to maintain the cleanliness of the surface of the grass-roots level; sealing primer before coating porous substrates should be brushing a layer of latex or solution type, to avoid the suction of the substrate on the coating uneven, causing flooding.

 artificial cultured stone veneer silicone rubber mold making methods and features!

    artificial cultured stone veneer the reason why more people are concerned about more natural culture stone, one of the reasons is because the color of the artificial culture stone Manufactured Stone Veneer colorful, but if the mold is not handled properly, it will affect the colors of culture stone.
    Generally, artificial culture stone mold plastic and silicone rubber to make molds, plastic molds for the early years of use, it has a relatively low cost advantage of, but the plastic mold is generally not enough fine, the color is more difficult on the go, pigments absorb low , so often there will be "painted face". In addition, the plastic mold when the mold production due to the high temperature melt molding, high energy consumption will smell pollution of the environment so it could not pass the EPA the EIA this off.
    
artificial cultured stone veneer mold silicone varieties developed in accordance with the special requirements of the production of culture stone. High, medium and low-end of its sub-six varieties. Culture stone mold silicone rubber has the same general resin mold silicone heat because of the particularity of the cultural production of stone materials, requirements, resistance to expansion as well as different hardness, acid and resistance to tearing, so as to adapt to the culture The stone mold special requirements proposal must not be mixed.
    In recent years, artificial cultured stone factory to produce culture stone mold silicone rubber, molding simple high yield, and the Silastic culture stone mold texture and delicate pigment absorption rate is higher, so the general large-scale artificial culture stone manufacturers use silicone rubber mold .
    Mold Silicone operation:
    1, silica and a curing agent was stirred uniformly, the appearance of silicone molds is flowing liquid, the A component is a silica gel, the B component is a curing agent, for example: 100 g of silica gel was added 2 g of the curing agent (Note: silica gel with a curing agent must To stir, did not stir, the mold will affect the life of the silicone mold curing dry and uneven situation and the number of molds from even cause mold scrapped.
    2, vacuum row of bubbles processing: silicone curing agent after mixing evenly vacuum row of bubbles aspects vacuum of time should not be too long, not more than 10 minutes, or silicone cured to produce a cross-linking reaction, can not be brushing or perfusion, resulting in material waste.
    3, brushing procedure: row of bubbles silica: brushing or perfusion fell on the mother die (in the brush mode or perfusion former master mold release agent or release agent) the brush mode must be uniform, sticky layer of gauze or a glass fiber cloth after 30 minutes to increase the strength of the mold and the tension during the second priming and then paste a layer of gauze or a glass fiber cloth, and then subjected to silica gel brushing After this treatment out of the mold, having life and turning model number, long service life, cost savings, and improve efficiency.
    4, the general approach of the outer mold production of the mold is surrounded by a plastic sheet or plank enclosed, one is using the plaster mold box filled can is used, another outer mold resin brushing brushing one layer resin coating layer of glass fiber cloth and then brushing then paste repeated two or three can be completed outside the mold.
    5, the ratio of silica gel (silica gel, silicon) with a curing agent to reflect the situation: It is recommended that the amount of curing agent to be added is not more than 5%, the greater the proportion of curing agent to be added, the faster the curing time, the mold is more brittle, and short service life. The amount of added silicone oil molding better attention to the silicone oil should not be excessive (5% -10%), or affect the tensile and hardness of the silicone mold can also be based on product and process requirements.
Artificial cultured Manufactured Stone Veneer silicone mold features:
    1, good fluidity, good operating
    2, stretch, pull good tensile tear.
    3, moderate hardness, good mold release, no deformation.
    Its production of artificial culture stone:
    1, the original stone samples directly molds from the pouring, texture, color like heaven, uniform color, and the deployment of color based on the architectural design requirements.
    2, low water absorption (17,2%), can be directly used for the exterior walls.
    3 fold intensity up to 3,4 MPa, durable easy to damage, especially the surface strength of up to 12,8 Mpa, dense wear-resistant, not powder.
    4, the shrinkage rate is low (less than 0,5 mm / m) the cracking phenomenon does not appear.
    5, freeze-thaw resistance, -20 ℃ freezing and thawing 15 times up to 10,7 MPa compressive strength is still fully able to cope with the North and the South to a variety of complex outdoor environment.
    6 low bulk density, bulk density less than natural stone half greatly reduce wall load. 7, excluding radioactive substances, environmental radiation.

Stone industry there are three major trends


It is still general consulting released "Stones 2013-2017 market research report shows: 10 years ago, the development of China's stone industry there is a certain blindness, lack of scientific master plan, resulting in a waste of resources, environmental pollution, ecological damage. Increasing emphasis now with the various areas of resource-saving and environmental protection issues, and to reduce the waste of resources, destruction of the ecological environment phenomenon. The future, as the sustained, steady development of China's economy, the development of China's stone industry will become increasingly large, the momentum gradually become stronger. The stone industry is increasingly focused on the green, the stone industry will usher in a more beautiful spring.
Of Veneer Stone Manufacturers and the Suppliers stone industry after years of development, gradually from serious pollution, low technical content, relying on hand-made development into low-carbon, mainly machinery production, industrial clusters as a fulcrum of modern industry. China's stone industry to achieve such a development the industry internal structural adjustment are inseparable. Stone industry presents a cluster development. In recent years, the number of domestic stone industry cluster growing, expanding, and more than 30 stone industry has a certain scale. The stone industry clusters led to the development of logistics and transport, machinery maintenance, construction and installation, and other related industries, which also led to the development of the regional field.
Still the general consulting building materials industry analyst pointed out: the future, there are three major trends in the stone industry.
First: A few years ago, the focus of the development of stone industry is the selection of the materials used, the key now is technology, some natural stone thinning process so opaque jade or striped marble, granite, quartz stone becomes translucent, so that translucent effect, bring new possibilities for use in interior design. The backlight lighting natural stone or become the next darling.
Second: With the deepening of the concept of green, green, high-quality alternative to have begun to appear. This will push the stone industry into a new round of development stage. The concept of green building is becoming more and more popular, in addition to the artificial stone, the stone industry can be some waste materials recycling, made of new materials, these can save resources, in addition to the development of new materials, can also be green elements of financial into the design concept. Future, artificial cultured stone veneer stone industry into the era of green creative.
Third: decoration industry will be an extension of the stone industry, stone has been more and more widely used in the kitchen and bath industry.

 Tile decoration of home improvement main material, living room, kitchen, bathroom and balcony, tile essential. Ceramic stone, there are slip resistant, free from pollution, easy to clean, good acid degree, good weather resistance inherent excellent performance by the favor of the high-end building materials market at home and abroad.
The imitation stone full cast glaze into new trends in the ceramic industry



Tile decoration of home improvement main material, living room, kitchen, bathroom and balcony, tile essential. In 2012, Zhuzhou tile market trends have? Which products are popular with consumers do?
The imitation stone full cast glaze into new trends
Reporter visited found that the consumption of home decoration tiles, tiles, full polished glaze, porcelain tiles, artificial cultured stone veneer still dominate the mainstream. Imitation of natural stone polished glaze products is the new trend this year.
The marble grand atmosphere, low-key luxury basalt, beautiful crystal porcelain ...... Veneer Stone Manufacturers and Suppliers With advanced 3D inkjet technology, full polished glaze tiles not only avoid the defects of natural stone, also perfectly reproduce grain and texture of natural stone to create a natural stone like the Seven Wonders of rhyme.
"Combines polished tiles, glazed tiles advantages of full polished glaze tile brightness than polished tiles, glazed pattern is very rich, strong sense of color, the suit style diversification." Marco Polo tiles of Zhuzhou marketing center manager Zeng ultra-polished glaze The tiles will become light brick mainstream.
Imitation stone full polished glaze appears cater to consumer psychology. The one tile Zhuzhou Marketing Center director Ding Sue full polished glaze is smooth and bright appearance is consistent with the current people's fast-paced lifestyle. In today's rapid economic development, people do not have the time to enjoy a life of pleasure and leisure. Therefore, the appearance of smooth and bright, rich color texture polished glaze products, has become the new darling of the people.
Ceramic stone sells high-end market
Began to rise from the second half of last year, the strength of the manufacturers are doing ceramic stone. "Zhou Lijuan, the ceramic stone very popular part of the high-end customers welcome.
The so-called ceramic stone, 3mm-5mm layer of glass composite ceramic glass surface of the fossil, fully integrated high-tech products in the secondary sintering, the line known as the glass-ceramic composite sheet. Imitate texture of the surface of the seemingly natural growth in fact change different, bright colors, layering, decorative appearance very good results.
, Microcrystalline stone also slip resistant, free from pollution, easy to clean, good acid and alkali degree, good weather resistance inherent excellent performance by the favor of the high-end building materials market at home and abroad.
The Zhuzhou market, the price of ceramic stone from 400-1000 dollars. Zhou Lijuan estimated, as the technology is maturing, 2012, microcrystalline stone product price may be reduced.
Tile backdrop favored
A middle-aged man in carefully selected varieties, different styles of tile: "I want to pick a suitable restaurants backdrop."
"Now many customers like the tiled guest at the restaurant of artificial  artificial cultured stone veneer backdrop." Person in charge of the marketing center analysis Pan Hongqi Road, tiled walls, both to protect the wall, sound and engage in health can seem decoration more on the grade.
The tile pattern specifications diversification better meet the individual needs of the people. It is understood that the current tile has long plane tiles, in the traditional sense simple grid, flowers, pattern development to the three-dimensional tiles and three-dimensional pattern. The tiles now not only in the choice of design patterns pursuit of simple but elegant, engaging, size also to break the tradition of the uniform, plus any bold combination of floral tiles showing more changes. Zeng the ultra also believe that, compared with traditional wallpaper, diatom mud, personalized custom tile backdrop, not only to increase the wall three-dimensional, so that the space structured; more general decorations can not reach the artistic charm, grade The crowning touch of home.
