How do you make methylcellulose?

Firstly, the cellulose raw material wood pulp/refined cotton is crushed, then alkalized and pulped under the action of caustic soda. Add olefin oxide (such as ethylene oxide or propylene oxide) and methyl chloride for etherification. Finally, water washing and purification are carried out to fina... Read More

What is starch ether used for?

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-modified and modified cellulose ethers. It is suitable ... Read More

Cellulose Ether Technologies for Organic Wastewater Treatment

Cellulose Ether Technologies for Organic Wastewater Treatment The wastewater in cellulose ether industry is mainly organic solvents such as toluene, oliticol, isopate, and acetone.

Effect of hydroxyethyl cellulose ether on early hydration of CSA cement

Effect of hydroxyethyl cellulose ether on early hydration of CSA cement The effects of hydroxyethyl cellulose (HEC) and high or low substitution hydroxyethyl methyl cellulose (H HMEC, L HEMC) on the early hydration process and hydration products of sulfoaluminate (CSA) cement were studied. The re... Read More

Water-soluble cellulose ether derivatives

Water-soluble cellulose ether derivatives The crosslinking mechanism, pathway and properties of different kinds of crosslinking agents and water-soluble cellulose ether were introduced. By crosslinking modification, the viscosity, rheological properties, solubility and mechanical properties of wa... Read More

How to make Cellulose ether?

How to make Cellulose ether? Cellulose ether is a kind of cellulose derivative obtained by etherification modification of cellulose. It is widely used due to its excellent thickening, emulsification, suspension, film formation, protective colloid, moisture retention, and adhesion properties. It p... 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, Sodium CMC HV 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 ... 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
