The role of dispersible polymer powder in thermal insulation mortar
Dry-mixed mortar is a kind of granule and powder that is uniformly mixed with additives such as fine aggregates and inorganic binders, water-retaining and thickening materials, water-reducing agents, anti-cracking agents, and defoaming agents in a certain proportion after drying and screening. Th...Read more -
Analysis of water resistance principle of redispersible latex powder type putty
Redispersible latex powder and cement are the main bonding and film-forming substances of water-resistant putty. The water-resistant principle is: During the mixing process of redispersible latex powder and cement, the latex powder is continuously restored to the original emulsion form, and the l...Read more -
Properties and applications of ethyl cellulose
Physical and chemical properties of ethyl cellulose: Ethyl cellulose (EC) is an organic soluble cellulose ether made from natural cellulose as the main raw material through chemical reaction processing. It belongs to non-ionic cellulose ethers. Appearance is white to slightly yellow powder or gra...Read more -
Dissolution method and main use of ethyl cellulose
The most commonly used mixed solvents for ethyl cellulose (DS: 2.3~2.6) are aromatic hydrocarbons and alcohols. Aromatics can be used benzene, toluene, ethylbenzene, xylene, etc., the dosage is 60~80%; alcohol can be methanol, ethanol, etc., the dosage is 20~40%. The EC was slowly added to the co...Read more -
Use HEC Hydroxy Ethyl Cellulose to Thicken Liquid Soaps
In the past few days, students have been troubled by the thickening of liquid soaps. In fact, to be honest, I rarely thicken liquid soaps. However, I have also taught in class that there are many ways to achieve this. The substances and thickening methods introduced today can as an alternative. c...Read more -

The advantages of redispersible polymer powder in cement dry mortar
It is necessary to add redispersible polymer powder to the cement dry mortar, because the redispersible polymer powder mainly has the following six advantages, the following is an introduction for you. 1. Improve adhesive strength and cohesion Redispersible polymer powder has a great effect on im...Read more -
Functions of redispersible polymer powder
Redispersible polymer powder is a free-flowing polymer white powder that can be easily re-emulsified and dispersed in water to form a stable emulsion. It can be mixed with other powdered materials such as cement, sand, lightweight aggregate, etc. in the production factory according to a certain r...Read more -

At present, there are more and more varieties of ceramic tiles on the market. The water absorption rate of ceramic tiles is relative...Read more -
Redispersible Polymer Powder In Mortar
The redispersible polymer powder RDP can be quickly redispersed into an emulsion after contacting with water, and has the same properties as the initial emulsion, that is, a film can be formed after the water evaporates. This film has high flexibility, high weather resistance and resistance to va...Read more -
The difference between redispersible polymer powder and resin powder
In recent years, a lot of resin rubber powder, high-strength water-resistant redispersible polymer powder and other very cheap rubber powder have appeared on the market to replace the traditional VAE emulsion (vinyl acetate-ethylene copolymer), which is spray-dried and recyclable. Dispersible lat...Read more -
What is the function of redispersible polymer powder?
The film of redispersible polymer powder RDP is elastic and tough, in the rigid skeleton formed by the hydration of cement mortar. Between the particles of the cement mortar, it functions like a movable joint, which can bear high deformation loads, reduce the stress, and improve the tensile and b...Read more
