Comprehensive Analysis of Thickening and Thixotropy of Cellulose Ether(1) Consistency can also be adjusted by choosing particle size and choosing cellulose ethers with different degrees of modification. The so-called modification is to introduce a certain degree of substitution of hydroxyalkyl groups on the skeleton structure of MC. By changing the relative substitution values of the

The thickening effect of cellulose ether depends on: the degree of polymerization of cellulose ether, solution concentration, shear rate, temperature and other conditions. The gelling property of the solution is unique to alkyl cellulose and its modified derivatives. The gelation properties are related to the degree of substitution, solution concentration and additives. For hydroxyalkyl modified

Daily chemical grade hypromellose is a synthetic polymer made from refined cotton through chemical modification. Cellulose ether is a derivative of natural cellulose. The production of cellulose ether is different from synthetic polymers. Its basic material is cellulose, a natural polymer compound. Due to the particularity of the natural cellulose structure, the cellulose itself has

What is cellulose ether?

What is cellulose ether? Expanding the high value-added utilization of cellulose-based natural resources is the need of the national renewable resources development strategy. It is one of the hotspots in the development of global economy, energy and new materials. Cellulose ether is an important cellulose derivative. It is a general term for a variety of

Determination of cellulose ether quality by HPMC combustion

By |2023-02-13T07:01:50+00:00June 21st, 2022|Industry News|

The quality of cellulose ether is influenced by many aspects. So how can we judge the quality of cellulose ether from the ash content of HPMC after combustion? First we need to understand what ash is. (1)Ash, also known as scorch residue, can simply be understood as impurities inside the product. They are naturally produced

Precautions when adding cellulose ether to putty powder Cellulose ether is commonly used in the fields of insulation mortar masterbatch, putty powder, asphalt roads and gypsum products, and have the ability to improve and enhance the characteristics of building materials and enhance the stability of production and construction suitability. The following is an introduction to

The effect of cellulose ether viscosity on the performance of gypsum mortar

By |2023-02-13T08:03:02+00:00June 16th, 2022|Industry News, Product Applications|

Viscosity is an important parameter for the performance of cellulose ethers. So what effect does the viscosity of cellulose ether have on the performance of gypsum mortar? Generally speaking, the higher its viscosity, the better the water retention effect of the gypsum mortar. However, the higher the viscosity, the higher the molecular weight of the

Several factors influence the viscosity of HPMC

By |2023-02-14T06:11:16+00:00June 16th, 2022|Industry News|

Several factors influence the viscosity of HPMC. The addition of hydroxypropyl methyl cellulose (HPMC) to the cementitious material has a thickening effect. And the amount added determines the water requirement of the cementitious material and therefore affects the yield of the mortar. Several factors affecting the viscosity of hydroxypropyl methyl cellulose (HPMC): The higher the

Effect of cellulose ethers on tile adhesives(1)

By |2023-02-15T02:34:33+00:00June 14th, 2022|Product Applications|

Effect of cellulose ethers on tile adhesives Cement-based tile adhesive is the largest current application of special dry-mix mortar, which is a mixture of cement as the main cementitious material. Cement-based tile adhesive is supplemented by a mixture of graded aggregates, water retention agents, early strength agents, emulsion powder and other organic or inorganic admixtures.
