differences between redispersible emulsion powder and resin glue powder

In recent years, there are a lot of resin rubber powder, high strength water resistant rubber powder and other very cheap rubber powder to replace the traditional VAE emulsion (vinyl acetate - ethylene copolymer) based, spray-dried dispersible emulsion powder, so what is the difference between resin rubber powder and dispersible emulsion powder, resin rubber powder can replace the dispersible emulsion powder? The following is a brief analysis of the difference between the two for your reference.

 

The characteristics, applications and differences between redispersible emulsion powder and resin glue powder

Redispersible emulsion powder

At present, the global widely used dispersible emulsion powders are: vinyl acetate and ethylene copolymer powder (VAC/E), ethylene and vinyl chloride and vinyl laurate terpolymer powder (E/VC/VL), vinyl acetate and ethylene and advanced fatty acid vinyl ester terpolymer powder (VAC/E/VeoVa), these three dispersible emulsion powders dominate the whole market, especially the vinyl acetate and ethylene copolymer powder. These three types of dispersible emulsion powders dominate the overall market, especially the vinyl acetate and ethylene copolymer powder VAC/E, which holds a leading position in the global field and represents the technical characteristics of dispersible emulsion powders. In terms of technical experience with polymers applied to mortar modification, it remains the best technical solution for.

1. being one of the most used polymers in the world.

2. has the most experience in applications in the construction sector

3. can meet the rheological properties (i.e. the required workability) required for mortars.

4, with other monomers of polyresins with low organic volatile compounds (VOC) and low irritant gas characteristics.

5, with excellent UV resistance and good heat resistance and long-term stability characteristics.

6, with high anti-saponification properties.

7, with the widest glass transition temperature range (Tg).

8, with relatively good integrated bonding, flexibility and mechanical properties.

9, has the longest how to produce stable quality products of chemical production experience and experience in maintaining storage stability.

10, extremely easy and performance of the protective colloid (polyvinyl alcohol) combined

 

The characteristics, applications and differences between redispersible emulsion powder and resin glue powder

 

Resin glue powder

Most of the "resin" glue powder on the market contain DBP, a chemical that you can check out for its harmful effects on male sexual function. A large number of these gum powders are piled up in warehouses and laboratories, and they have certain volatility. The market in Beijing, which is famous for its "glue powder", is now a kind of "glue powder" soaked in solvent with various names: high-strength water-resistant glue powder, resin glue powder, etc. Typical characteristics: 

1, dispersion is not good, some feel wet, some feel flocculent (should be seafoam-type porous material) some do white slightly dry but still very bad smell.

2, smell very pungent smell

3, some added color, the current color has appeared white yellow, gray, black, red, etc.

4, The amount of addition is very little, a ton of addition in 5~12 kg

5, early strength is amazingly good, three days cement is not yet strength, can already be corroded off the insulation board sticky bad

6, it is said that XPS board can be used without interface agent

Through the samples obtained so far, it can be concluded that the light-weight porous material adsorption of solvent-based resin, but the supplier wants to deliberately avoid the word "solvent", so called "rubber powder"

 

Disadvantages.

1, solvent weatherability is a big problem, in the sun, it will not take long to evaporate, even if it is not in the sun, bonding interface, due to the construction of the cavity, will also be decomposed relatively quickly

2, aging resistance, solvent is not temperature-resistant, which we all know

3, due to the mechanism of bonding is dissolved off the interface of the insulation board, and vice versa, is also destroyed the bonding interface, this problem in the later stages if the problem, the impact is fatal

4, there is no precedent for foreign applications, with foreign experience in mature basic chemical, it is impossible not to find this material

What is Carboxymethyl Cellulose (CMC)?

图片
Carboxymethyl Cellulose (CMC)   is a versatile and widely used derivative of cellulose, which is a natural polymer found in plant cell walls. CMC is synthesized through the chemical modification of cellulose, resulting in the substitution of hydroxyl groups with carboxymethyl groups. This modification enhances the water solubility and rheological properties of cellulose, making CMC an essential ingredient in various industries. CMC has a linear structure and is composed of repeating units of glucose molecules linked together. The carboxymethyl groups are attached to the glucose units, imparting anionic properties to CMC. The degree of substitution (DS) refers to the average number of carboxymethyl groups per glucose unit and determines the properties of CMC, including its solubility, viscosity, and stability. One of the primary characteristics of CMC is its excellent water solubility. When dispersed in water, CMC forms colloidal solutions or gels depending on the concentration. Thi...
