How effective is hydroxyethyl cellulose as a thickener?
Cellulose is a polysaccharide that forms a variety of water-soluble ethers. Cellulose thickeners are nonionic water-soluble polymers. Its use history is very long, more than 30 years, and there are many varieties. They are still used in almost all latex paints and are the mainstream of thickeners...Read more -
What is the effect of hydroxypropyl methylcellulose on cement mortar?
Hydroxypropyl methylcellulose can improve the dispersion resistance of cement mortar. Hydroxypropyl methylcellulose is a water-soluble polymer compound. It generally increases the consistency of the mixture by increasing the viscosity of the mixing water. It can be dissolved in water to form a vi...Read more -
How to detect the ash content of hydroxypropyl methylcellulose?
Ash content is an important indicator of hydroxypropyl methylcellulose. Many customers often ask when they understand hydroxypropyl methylcellulose: what is the ash value? Hydroxypropyl methylcellulose with a small ash content means higher purity; cellulose with a large ash content means that the...Read more -
How to choose hydroxypropyl methylcellulose for plaster mortar?
The general pH value of gypsum products is acidic or neutral. Now there are two types of construction grade hydroxypropyl methylcellulose on the market: slow-dissolving cellulose and instant cellulose (S). Instant cellulose is not suitable for gypsum systems. Products, the solubility is very poor...Read more -
The effect of adding cellulose to putty powder
When we use putty powder, there will often be some problems, so we don’t know the reason. I think there should be seven kinds of problems that often appear in putty powder! One: Do it fast. This is mainly related to the addition of ash calcium and the water retention rate of the fiber, an...Read more -
The use of hydroxypropyl methylcellulose, how to distinguish the quality of HPMC simply and intuitively
What is the main use of hydroxypropyl methylcellulose? ——Answer: HPMC is widely used in construction materials, coatings, synthetic resins, ceramics, medicine, food, textiles, agriculture, cosmetics, tobacco and other industries. HPMC can be divided into construction grade, food grade and pharmac...Read more -
What is the reason for the unstable setting time of dry-mixed mortar?
The setting time of dry-mixed mortar in the national standard is 3-8 hours, but the setting time of many dry-mixed mortars is unstable. Some mortars set for a long time and do not solidify for a long time. But it is prone to cracking in the later stage. So why is dry-mixed mortar prone to unstabl...Read more -
What is the relationship between the ash content of hydroxypropyl methylcellulose and the quality of cellulose?
First of all, we need to know what is ash? When burning at high temperature, hydroxypropyl methylcellulose undergoes a series of physical and chemical changes, and finally the organic components volatilize and escape, while the inorganic components (mainly inorganic salts and oxides) remain, and ...Read more -
Dissolving method and determination method of hydroxypropyl methylcellulose HPMC
test methods Method name: hypromellose—determination of hydroxypropoxy group—determination of hydroxypropoxy group Scope of application: This method uses the hydroxypropoxy determination method to determine the content of hydroxypropoxy in hypromellose. This method is applicable to hy...Read more -
Can resin rubber powder replace redispersible latex powder?
As a non-ionic surfactant, hydroxyethyl cellulose has the following properties in addition to thickening, suspending, bonding, floating, film-forming, dispersing, water retention and providing protective colloid. Hydroxyethyl cellulose (HEC we all It is known that both hydroxyethyl cellulose HEC ...Read more -
How much do you know about the various applications of cellulose and its derivatives?
About Cellulose Cellulose is a macromolecular polysaccharide composed of glucose. It exists in large quantities in green plants and marine organisms. It is the most widely distributed and largest natural polymer material in nature. It has good biocompatibility, renewable and Biodegradable and oth...Read more -
The quality of cellulose determines the quality of mortar, what do you think?
In ready-mixed mortar, the addition amount of cellulose ether is very low, but it can significantly improve the performance of wet mortar, and it is a main additive that affects the construction performance of mortar. Reasonable selection of cellulose ethers of different varieties, different visc...Read more
