What should be paid attention to in the configuration of sodium carboxymethyl cellulose
In the process of configuring sodium carboxymethyl cellulose, our usual practice is relatively simple, but there are several that cannot be configured together. First of all, it is strong acid and strong alkali. If this solution is mixed with sodium carboxymethyl cellulose, it will cause fundamen...Read more -
How to make CMC Sodium Carboxymethyl Cellulose?
Sodium carboxymethyl cellulose (CMC) is a carboxymethylated derivative of cellulose, also known as cellulose gum, and is the most important ionic cellulose gum. CMC is usually an anionic polymer compound obtained by reacting natural cellulose with caustic alkali and monochloroacetic acid. The mol...Read more -
Properties of sodium carboxymethyl cellulose
Sodium carboxymethyl cellulose is an anionic cellulose ether with white or slightly yellow flocculent fibrous powder or white powder in appearance, odorless, tasteless and non-toxic; easily soluble in cold or hot water to form a transparent solution with a certain viscosity , the solution is neut...Read more -
A brief analysis of the types and main physical and chemical properties of adhesives
Natural adhesives are commonly used adhesives in our lives. According to different sources, it can be divided into animal glue, vegetable glue and mineral glue. Animal glue includes skin glue, bone glue, shellac, casein glue, albumin glue, fish bladder glue, etc.; vegetable glue includes starch, ...Read more -
Application of hydroxyethyl cellulose in latex paint
The thickener for latex paint must have good compatibility with the emulsion polymer compound, otherwise the coating film will have a small amount of reticulate, and will produce irreversible particle agglomeration, which will reduce the viscosity and coarsen the particle size. The thickener will...Read more -
Analysis of the reasons for the influence of different hydroxyethyl cellulose addition methods on the latex paint system
The thickening mechanism of hydroxyethyl cellulose is to increase the viscosity through the formation of intermolecular and intramolecular hydrogen bonds, as well as hydration and chain entanglement of molecular chains. Therefore, the thickening method of hydroxyethyl cellulose can be divided int...Read more -
Pharmacy Polymer Materials
1. Croscarmellose sodium (cross-linked CMCNa): a cross-linked copolymer of CMCNa Properties: White or off-white powder. Due to the cross-linked structure, it is insoluble in water; it swells rapidly in water to 4-8 times its original volume. The powder has good fluidity. Application: It is the mo...Read more -
Effects of HPMC on water retention, thickening and fluidity of mortar
Figure 1 shows the change of water retention rate of mortar with the content of HPMC. It can be seen from Figure 1 that when the content of HPMC is only 0.2%, the water retention rate of mortar can be significantly improved; when the content of HPMC is 0.4%, the water retention rate has reached 9...Read more -
Application of Domestic Hydroxypropyl Methyl Cellulose in Production of High Polymerization Degree of Polyvinyl Chloride
Abstract: The application of domestic hydroxypropyl methylcellulose instead of imported one to the production of PVC with high polymerization degree was introduced． The effects of two kinds of hydroxypropyl methylcellulose on the properties of PVC with high polymerization degree were investigate...Read more -
Redispersible polymer powder of dry mix mortar additives series
n the actual environment of the market, various types of latex powders can be described as dazzling. As a result, if the user does not have his own professional technicians or testing equipment, he can only be fooled by many unscrupulous merchants in the market. At present, there are some so-call...Read more -
The role of redispersible polymer powder in dry mortar
Redispersible polymer powders are dispersions of polymer emulsions after spray drying. With its promotion and application, the performance of traditional building materials has been greatly improved, and the bonding strength and cohesion of the materials have been improved. Redispersible latex po...Read more -
Application of dispersible polymer powder in building materials industry
When it comes to re-dispersible polymer powder, I believe that all my friends are very concerned about this issue. Because in the process of specific project construction, the product has a very wide range of applications, and practice has proved that its performance is reliable. Under the guidan...Read more
