Sodium Carboxymethyl Cellulose

CMC is one of the most important water soluble high polymer cellulose ethers. The company production of Dexin sodium carboxymethyl cellulose can be used as emulsifier, thickening agent, sizing agent, film-forming agent and binder, because it has the general characteristics of many natural rubber and synthetic rubber does not, so in recent years has been widely used in tobacco, synthetic detergent and soap industry, textile printing and dyeing industry, oil drilling mud papermaking industry, food industry, paint industry, slag, fertilizer, medicine, and other sports products, daily chemical industry and civil construction industry. Practice has proved that the use of instant CMC not only can play a unique role in it, but also save the industrial food, synthetic rubber products are rare, in order to apply the popularization and promotion of CMC, facilitate the selection of varieties, special preparation of the product description, for reference.
Chemical name: sodium carboxymethyl cellulose, also known as carboxymethyl cellulose
Molecular formula: [C6H7O2 (OH) 2CH2COONa]n
Application of industrial products
1, for the textile printing and dyeing industry, the textile industry will be instant CMC as sizing agent for cotton, wool, silk, chemical fiber, blended fabric sizing gauze;
2, CMC can be used for instant paper industry paper smoothing agent, sizing agent in papermaking industry. Adding 0.1% ~ 0.3% instant CMC can make paper strengthening anti tension 40% ~ 50% in the pulp, the compressive fracture degree increased 50%, increased 4 ~ 5 times of kneading.
In 3, the building materials industry: can be used for walls, stucco, caulking etc. in the mechanical construction, as retarder, water retaining agent, thickening agent and binding agent. CMC can add instant paint, thickening and water retention, has retarding effect, even in large-scale construction, but also can improve the strength of the building. For plaster plaster, waterproof putty, caulking gypsum, gypsum binder, can significantly improve the water retention, bond strength, and has good workability, no cracking etc..
4, CMC for instant detergent: prevent dirt redeposition effect to the detergent, also can make the slurry or liquid soap washing effectively and the thickening composition of stable structure.
5, paint: paint storage period is a very important feature, the paint can be in the absence of dehydration shrinkage and viscosity does not reduce the conditions of good preservation. In the application of CMC in the instant test after warming up, paint no syneresis and can maintain stable viscosity.
Instant carboxymethyl cellulose dissolution method:

The instant carboxymethyl cellulose added uniform mixing water, manual stirring 5 minutes 3. In order to homogenize the solution, place 20 minutes and stir for about 3 - 5 minutes. Even if the operation is not because of Baotuan error. Save investment and reduce costs. The solution is stable and can be placed for a long time.

What are the uses and models of sodium carboxymethyl cellulose?
1 sodium carboxymethyl cellulose alias hydroxypropyl methyl cellulose; cellulose hydroxypropyl methyl ether; Hypromellose, Cellulose. This product is made from highly pure cotton cellulose as raw material, under alkaline conditions specially prepared etherification process, to complete the automation control, does not contain any animal organs and grease and other active ingredients. This product is non-ionic cellulose ether, the appearance of white powder, odorless tasteless.
2 Introduction
1 Construction: as water retaining agent, cement mortar retarder make mortar with pump. In the mortar, gypsum material, putty powder or other materials as adhesive, improve and extend the operational time of painting. It can also be used to paste ceramic tile, marble, plastic decoration, stick to strengthen agent, can also reduce the amount of cement. HPMC water retention of the smear after the slurry will not dry too fast and cracked, enhanced strength after hardening.
2 ceramic manufacturing: widely used as binder in the manufacture of ceramic products.
3 coating industry: in the coating industry as a thickening agent, dispersant and stabilizer, in water or organic solvents have good solubility. As a paint remover.
4 ink printing: in the printing industry as a thickening agent, dispersant and stabilizer, in water or organic solvents have good solubility.
5: plastic forming release agent, softening agent, lubricant etc..
6 polyvinyl chloride: polyvinyl chloride as dispersant in the production of polyvinyl chloride, the main auxiliary agent for preparing PVC by suspension polymerization.
7 other: This product is also widely used in leather, paper products, fruit and vegetable preservation and textile industry, etc.
