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

Ash content standard for redispersible polymer powder

The ash content from the regular redispersible polymer powder factory is generally 10±2 The ash content standard is within 12%, and the quality and price are comparable Some domestic latex powders are more than 30%, and even some rubber powders have as much as 50% ash. Now the quality and price o... Read More
