The role of methyl cellulose ether (CMC) Type of methyl cellulose ether A. Hydroxypropyl methyl fiber (HPMC), which is mainly made of high-purity refined cotton as a raw material, and is specially etherified under alkaline conditions. B. Hydroxyethyl methylcellulose (HEMC), a nonionic cellulose ether, has…
Effect of cellulose ether on tile adhesive 1. Introduction Cement based tile adhesive is the largest application of current special dry mortar. This is a mixture of organic or inorganic admixtures such as cement as the main cementitious material. And supplemented with grading aggregates, water…
Physical properties of construction grade cellulose 1. Appearance: White or quasi-white powder. 2. Granularity; the passing rate of 100 mesh is more than 98.5%; the passing rate of 80 mesh is more than 100%. 3. Dissolve in water and some solvents, such as appropriate proportion…
The role of HPMC in wet mortar Hydroxypropyl methylcellulose is used as a water retaining agent and retarder for cement mortar to make the mortar pumpable. In the plaster as a binder,so improve the spreadability and extend the operation time. The water retention of hydroxypropyl…
The importance of HPMC in retaining water from mortar First, the necessity of water retention Water retention of mortar It refers to the ability of mortar to retain moisture and water retention. It is easy to be separated from water during transportation and storage. That…
CMC – Food Additives CMC is divided into detergent, food additive and toothpaste ,which mainly distinguish purity and degree of substitution. Because cmchas the functions of thickening, stabilizing and water retaining it is widely used in various solid or liquid drinking, meat products, instant food, candies,…
Factors affecting HPMC viscosity 1, the relationship with the degree of polymerization The viscosity of the hydroxypropyl methylcellulose solution is proportional to the degree of polymerization (DP) or molecular weight or molecular chain length, while other parameters are unchang. The degree of polymerization is increased,…
What is the difference between hydroxypropyl methylcellulose (HPMC) without S? 1. HPMC is divided into fast-dissolving and slow-dissolving types. The HPMC instant solubility is suffix with the letter S, such as 100000S for 100,000 viscosity fast-dissolving HPMC, which is treat with glyoxal in the production…
Common questions about cellulose products and their applications Part III: Application of cellulose in facial film 1. Does cellulose used in the mask cause deformation of the film? We have recently selected more than 10 membranes for hydroxyethylcellulose application testing (contrast xanthan gum), which only…
Common questions about cellulose products and their applications Part 2: Application of cellulose in rinse-off formula 1. Using cellulose transparent paste (transparent hand soap, shower gel, shampoo), low temperature opaque, how to solve? HPMC is widely used in hand sanitizers, shower gels and shampoos. It…
