Methyl cellulose (MC)

Methylcellulose (MC) is widely used in construction, paint, paper, emulsion, food, medicine, textile and other industries.

The specific usage of carboxymethylcellulose sodium (CMC-Na) is as follows:

Admixture for cement, mortar, joint mortar, etc.

Thickener for paint.

Binders used as film-forming agents in cosmetics, medicine, and food industries.

Dispersant and film-forming agent for synthetic resin.

Textile printing and dyeing sizing agent and dyeing.

Hydroxypropyl methylcellulose (HPMC)

Hydroxypropyl methylcellulose (HPMC) is used as thickener, stabilizer, emulsifier and excipient in construction, coating industry, ceramics, papermaking, synthetic resin, textile industry, oil drilling and cleaning products and other industries. , water-retaining agent, film-forming agent, etc. Most of HPMC is used as putty powder, mortar, tile adhesive, gypsum slurry and industrial coating.

In construction, hydroxypropyl methylcellulose is mainly used in masonry mortar, external wall insulation mortar, tile bonding mortar, self-leveling mortar, gypsum mortar, self-leveling mortar, latex paint, etc.

Hydroxypropyl methylcellulose increases the fluidity, viscosity, water retention and retardation of the mortar, which is convenient for construction. Improve the initial strength of mortar and avoid cracking. Improve the anti-sag ability of mortar, bond strength, and prevent tiles from slipping.

Hydroxypropyl methylcellulose is used as a thickener in the coating industry to make the coating bright and delicate, prevent the gelation of the pigment, help the pigment to disperse, prevent powder removal, improve the stability and viscosity of the coating, and increase the leveling of the construction performance.

As the binder of ceramic glaze slurry, hydroxypropyl methylcellulose has the functions of suspension, decondensation and water retention, increases the strength of raw glaze, reduces the drying shrinkage of glaze, makes the embryo body and glaze firmly bonded, and is not easy to fall off.

Hydroxyethyl cellulose (HEC)

Hydroxyethyl cellulose (HEC) is widely used in cement mortar, gypsum putty, paint, ink, papermaking, toiletries, oil drilling, medicine and polymer polymerization industry as thickener, adhesive, water retention Agents, surfactants, colloidal protective agents, dispersants, stabilizers, emulsifiers, hydrophilic gels, skeleton materials, preparation of skeleton-type sustained-release preparations, etc.

Hydroxyethyl cellulose (HEC) is often used in the production of jelly, ointment, eye drops, suppositories, tablets, capsules and sustained-release preparations in medicine. effective time. They can mask bad or bad smells of medicines and improve their appearance.

Carboxymethylcellulose sodium (CMC-Na)

Carboxymethylcellulose sodium (CMC-Na) is widely used in petroleum, textile, daily chemical, papermaking, construction, food, medicine and other industrial sectors, and can be used as emulsifier, thickener, dispersant, stabilizer, Glue, film-forming agent, water-retaining agent, etc., known as "industrial monosodium glutamate".

The specific usage of carboxymethylcellulose sodium (CMC-Na) is as follows:

Oil industry drilling mud treatment agent. Organic detergent builder. Sizing agent for textile printing and dyeing. Water-soluble colloidal tackifier for daily chemical products. Viscosifier and emulsifier in pharmaceutical industry. Thickener for the food industry. Adhesives for the ceramic industry. Sizing agent for the paper industry. Used as a flocculant in water treatment, etc. It is used as a flocculant in water treatment, mainly used in wastewater sludge treatment, which can increase the solid content of filter cake.

As an ideal food additive, food-grade CMC-Na is widely used in food production in the food industry. Food-grade CMC-Na is a food preservative, which is applied on the surface of some foods to keep the food fresh to the greatest extent without causing adverse effects on human health. Food-grade CMC-Na is also a thickener, which has a certain thickening and emulsifying effect, and can be used to stabilize yogurt drinks and increase the viscosity of yogurt. Food-grade CMC-Na has a certain degree of hydrophilicity and rehydration, and can be used to improve the eating quality of pasta such as bread and steamed buns, prolong the shelf life of pasta products, and enhance the taste. Food-grade CMC-Na has a certain gel effect, which is conducive to better gel formation of food, and can be used to make jelly and jam.

Summary

MC, HPMC, HEC and CMC-NA are all cellulose ethers, which are used as thickeners in cement mortar, paint, ceramics, rubber, paper, cleaning products, medicine, food, textile, glue, sewage treatment, etc. Adhesives, water retaining agents, surfactants, dispersants, stabilizers, emulsifiers, excipients, film formers, etc.

They can increase the stability, water retention, cohesiveness, film-forming, enzyme resistance, dispersibility and thermal gelation of products, so that the products of the above industries can meet the different needs of people.
