China (Mainland) 
the article is used for oil, natural gas drilling, digging well etc
the slurry containing cmc can form thin and strong walls and low permeability
the filter cake reduces the water loss.
after adding cmc in the mud, the drill can get low initial cut
the force makes the mud easy to release the gas trapped inside, while also breaking up the debris
he was soon abandoned in the mud.
the drilling mud is the same as other suspension dispersions
in the period, the addition of cmc can make it stable and prolong the existence period.
the mud, containing cmc, is rarely affected by mold, so no need to
maintain a high ph value without using a preservative.
cmc is used as drilling fluid for drilling mud and can resist all kinds of soluble
pollution of sexual salts.
6 mud containing cmc, the stability is good, even if the temperature at 150 ℃
it can still reduce water loss.
cmc with high viscosity and high displacement is suitable for the less dense mud.
cmc with low viscosity and high replacement is suitable for dense mud.choose
cmc shall be determined according to the types of mud and the different conditions of areas and wells
.
the cmc is used in textile and printing and dyeing industry
agent, used in cotton, silk wool, chemical fiber, blending and other strong light yarn
sizing;
cmc is used in papermaking industry to make paper smooth
agent, sizing agent.add 0.1% ~ 0.3% cmc to the pulp
the paper increases the tensile strength by 40% ~ 50%, and the compression fracture increases by 50%.
the kneading increase is 4 ~ 5 times.
it can be used as an adsorbent in synthetic detergent.daily
chemical like toothpaste industry cmc glycerine water solution used as toothpaste glue
the base;pharmaceutical industry is used as thickener and emulsifier;cmc water solution increased
it is used as a plankton concentration.
it is used in ceramic industry for the adhesive, plasticizer and plasticizer.
the suspension of glazes, colouring agent and so on.
it is used in buildings to improve water retention and strength
