Applications of Hydroxyethyl Cellulose (HEC)
Hydroxyethyl cellulose (HEC) is a non-ionic cellulose ether made from natural polymer material cellulose through a series of etherification. It is an odorless, tasteless, non-toxic white powder or granule, which can be dissolved in cold water to form a transparent viscous solution, and the dissol...Read more -
What is the production process of methylcellulose?
What is the role of methyl cellulose ether in dry powder mortar? A: Methyl hydroxyethyl cellulose ether (MHEC) and methyl hydroxypropyl cellulose ether (HPMC) are collectively referred to as methyl cellulose ether. In the field of dry powder mortar, methyl cellulose ether is an important modified...Read more -
Daily Q&A on Gypsum Application Technology
What is the basic concept of starch ether? Answer: Starch ether is mainly used in construction mortar, which can affect the consistency of mortar based on gypsum, cement and lime, and change the construction and sag resistance of mortar. Starch ethers are usually used in conjunction with non-modi...Read more -
Application of CMC in Oil and Gas Industry
During drilling, drilling and workover of oil and natural gas, the well wall is prone to water loss, causing changes in the well diameter and collapse, so that the project cannot be carried out normally, or even abandoned halfway. Therefore, it is necessary to adjust the physical parameters of th...Read more -
Battery Grade Cellulose CMC-Na and CMC-Li
CMC Market Status: Sodium carboxymethyl cellulose has been widely used as a negative electrode material in battery manufacturing for quite a long time, but compared with the food and drug industry, construction industry, petrochemical industry, toothpaste production, etc., the proportion of CMC u...Read more -
Petroleum grade CMC-LV (petroleum grade low viscosity CMC)
In drilling and oil drilling engineering, good mud must be configured to ensure the normal operation of the drilling. Good mud must have appropriate specific gravity, viscosity, thixotropy, water loss and other values. These values have their own requirements depending on the region, well depth, ...Read more -
Petroleum grade high viscosity CMC (CMC-HV)
As a water-soluble colloid in the drilling mud system, CMC has a high ability to control water loss. Adding a small amount of CMC can control the water at a high level. In addition, it has good temperature resistance and salt resistance. It can still have a good ability to reduce water loss and m...Read more -
Application of CMC in Petroleum
Petroleum grade CMC model: PAC- HV PAC- LV PAC-L PAC-R PAC-RE CMC- HV CMC- LV 1. The functions of PAC and CMC in the oil field are as follows: 1. The mud containing PAC and CMC can make the well wall form a thin and firm filter cake with low permeability, reducing the water loss; 2. After adding ...Read more -
Additives for glazed tiles
01. Properties of sodium carboxymethylcellulose Sodium carboxymethyl cellulose is an anionic polymer electrolyte. The degree of substitution of commercial CMC ranges from 0.4 to 1.2. Depending on the purity, the appearance is white or off-white powder. 1. The viscosity of the solution The viscosi...Read more -
Classification of Cellulose
01 Hydroxypropyl Methyl Cellulose 1. Cement mortar: Improve the dispersion of cement-sand, greatly improve the plasticity and water retention of mortar, have an effect on preventing cracks, and enhance the strength of cement. 2. Tile cement: improve the plasticity and water retention of pressed t...Read more -
Application of CMC Binder in Batteries
As the main binder of water-based negative electrode materials, CMC products are widely used by domestic and foreign battery manufacturers. The optimal amount of binder can obtain relatively large battery capacity, long cycle life and relatively low internal resistance. Binder is one of the impor...Read more -
Super Viscosity CMC
CMC is white or milky white fibrous powder or granules, with a density of 0.5-0.7 g/cm3, almost odorless, tasteless, and hygroscopic. Easily dispersed in water to form a transparent colloidal solution, insoluble in organic solvents such as ethanol. The pH of 1% aqueous solution is 6.5 to 8.5. Whe...Read more
