The second effect of cellulose ether - thickening depends on: cellulose ether polymerization degree, solution concentration, shear rate, temperature and other conditions. The gelation property of solution is unique to alkyl cellulose and its modified derivatives. Gelation characteristics are related to degree of substitution, solution concentration and additives. For hydroxyl alkyl modified derivatives, gel properties
Cellulose ether plays an irreplaceable role in the production of building materials, especially dry mixed mortar. Especially in the production of special mortar (modified mortar), it is an indispensable and important part. The important role of water-soluble cellulose ether in mortar mainly has three aspects. One is excellent water retention ability. The second is the
CMC is cheap and dissolves in water to form a gelatinous solution with a reticulated structure. It has the function of thickening and stabilizing the paste, and is a common thickening agent for toothpaste at home and abroad. CMC is not actually dissolved in water, it is disaggregated, and when it encounters water, it first
Cellulose ether is a synthetic polymer made of natural cellulose as raw material by chemical modification. Cellulose ether is a derivative of natural cellulose, cellulose ether production and synthetic polymers are different. Its basic material is cellulose, a natural polymer compound. Due to the particularity of natural cellulose structure, cellulose itself has no ability to
HPMC without surface treatment do not dissolve in hot water above 85, but can swell and disperse in hot water. Usually, dissolving HPMC the following methods are used: 1. Conventional methods. Take about 1/5 to 1/3 of the required amount of hot water and stir to make the added product expand completely. Then add the
Hydroxypropyl methyl cellulose is divided into two kinds of ordinary hot soluble cold water instantly soluble. Hydroxypropyl methyl cellulose uses are: 1.Gypsum series In the gypsum series of products, cellulose ethers mainly use to retain water and increase smoothness. Together they play a certain alleviating role. It addresses concerns about drum cracking and initial strength
The other day's article gave you an introduction to why tiles can develop hollow drums. Today's article tells you how to solve the problem. Today's article shows you how to solve the problem and provides you with ways to prevent it from happening. Ⅰ.Solutions for tile bulging 1.Large tile bulging The number of more, it
Tiles are a big part of the process of decorating a house. And there are more and more types, from glazed tiles, to glass tiles, to fully glazed tiles and microcrystalline stone. Paving techniques also from the earliest emergence of cement mortar or fast sticky powder point sticky, to later use on-site mixing cement mortar
Re-dispersible Polymer Powder is a powder dispersion produced and processed from modified polymer emulsions. It has good redispersibility. It can be re-emulsified into a stable polymer emulsion even after the addition of water, and its chemical properties are identical to the initial emulsion. Therefore, it makes it possible to produce high quality dry-mixed mortar with.
The main reason for the blistering of Wall putty powder is the problem of the wall. If the wall is pitted, uneven, and has small pits. It must be blistered. And the amount of blistering depends on the shear force of hydroxypropyl methylcellulose. The higher the viscosity of cellulose, the more bubbles, and vice versa.
