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 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 -
Use and Contraindications of Carboxymethyl Cellulose
Mix sodium carboxymethyl cellulose directly with water to make a pasty glue for later use. When preparing sodium carboxymethyl cellulose paste glue, first add a certain amount of clean water into the batching tank with mixing equipment, and sprinkle sodium carboxymethyl cellulose slowly and evenl...Read more -
Two common problems in glaze debugging and use
In the process of debugging and using glazes, in addition to meeting specific decorative effects and performance indicators, they must also meet the most basic process requirements. We list and discuss the two most common problems in the process of using glazes. 1. The performance of glaze slurry...Read more -
Discussion on Stability of CMC Glaze Slurry
The core of glazed tiles is glaze, which is a layer of skin on the tiles, which has the effect of turning stones into gold, giving ceramic craftsmen the possibility to make vivid patterns on the surface. In the production of glazed tiles, stable glaze slurry process performance must be pursued, s...Read more
