Selection and differentiation of redispersible latex powder

With the implementation of building energy saving policy in China, it brings an opportunity for the rapid development of redispersible latex powder manufacturers. Therefore, many enterprises and individuals in the field of non building materials or non chemical materials have invested in redispersible latex powder enterprises. As early as 2004, the domestic market was only developed by a few foreign enterprises. After a few years of development, there were a number of R & D and production disturbances of redispersible latex powder in the market. After 2006, there were more production enterprises. The development momentum has changed the market situation and broken the situation that imported redispersible latex powder dominates the world.

But it is also because of the increasing investment in redispersible latex powder enterprises, fierce market competition, the industry is not standardized, there are a large number of resin powder, mortar powder, putty powder, tile bonding powder and other low-cost, simple technology products, the sales price is several times different from redispersible latex powder, in order to compete for market share, of course, many production putty powder, sand Pulp enterprises do not know that those that are prohibited by the state are poisonous, have a strong chemical taste, and are corrosive, which have a great impact on pollution.

The market is not short of some enterprises with the name of redispersible latex powder to produce some low-quality latex powder. First of all, we should distinguish between poor dispersion. Some feel wet, some feel flocculent (it should be porous sepiolite material), and some do white, slightly dry but still smelly. 2. It smells very pungent. 3. Some of them have added colors. At present, the colors are white, yellow, gray, black, red, etc. 4. The amount added is very small. The amount added per ton is 5-12kg. 5. The early strength is amazing. The cement has no strength in three days, and it can corrode and stick the insulation board. Attention should be paid to 1. Glass transition temperature: the lower the glass transition temperature is, the better the flexibility is, the lower the adhesion is, and vice versa. 2. Fluidity: in dry powder mortar products, self leveling and grouting materials and some brushing permeable waterproof materials need to consider the influence of latex powder on the fluidity of the system. 3. Anti caking agent: the addition of anti caking agent will have a great influence on the adhesion, which needs to be concluded through the adhesion test. 4. It is not that only one kind of rubber powder can be used in a formula system. Sometimes flexible and rigid rubber powder can be used together to obtain the best adhesion under the appropriate flexible condition.

Therefore, our enterprise should not destroy the reputation of the enterprise because of a little bit of cost. Secondly, we should distinguish the quality of the rubber powder. A few days ago, Xiao Bian watched the news at home and was surprised to hear about the brittle problem of the existing building in Wuhan. Experts said that the reason is the rubber powder problem of the thermal insulation mortar. The quality of the selection is poor, the film-forming property is not good, the solid content is low and the chemical flavor is very heavy. According to the current national policies and regulations The construction party and the production enterprise will pay huge economic losses. If the circumstances are serious, they will have criminal responsibility. It can be said that Xiaobian has made a cold sweat for the production enterprise.

The redispersible latex powder produced by Shandong Chuang Yao Biotechnology Co., Ltd. is made from imported VAE emulsion. It is green and environment-friendly. It has no chemical smell, no toxicity, chemical washing and cold water dissolution. Welcome to consult.
