Hydroxypropyl MethylCellulose

Hydroxypropyl methyl cellulose

HS Code:3912,900

CAS:9004-65-3

Hydroxypropyl methyl cellulose is a kind of white or slightly yellowish powder, odorless, tasteless, and non-toxic. The product can be dissolved in cold water to form a transparent viscous solution. The aqueous solution of this product has surface activity so that it has emulsification, protective colloids and relative stability. PH Stability: the aqueous solution viscosity of this product is relatively stable in the range of PH 3.0—11.0. As the product is non-ionic, and in the preparation process can be effectively purified by washing with hot water, it has a very low ash content. Hydroxypropyl methylcellulose products can fully meet the standards for use of medicine, food, construction and personal care products.

sodium gluconate construction retarder(hs code 2918160000) technical

Sodium Gluconate Applications:

 (1)Used as a cement admixture: after a certain amount of sodium gluconate is added into the cement, it can improve the plasticity and strength of the concrete, and has retardation effect, namely postpone the initial and final setting time of the concrete;    

vicky

sodium lignosulphonate Technical 97%

Sodium Lignosulphonate ( lignosulfonate ) water reducer are mainly for concrete mixture as water-reducing additive. Low dosage , low air content , water reducing rate is high ,adapt to most kind of cement. Can confected as concrete early-age strength enhancer , concrete retarder , antifreeze , pumping aids etc. Nearly no precipitate product in the liquor additive which is made from The sodium lignosulphonate and Naphthalin-Group High-Efficiency Water Reducer .The sodium Lignosulphonate is fit for apply to building project, dam project, thruway project etc.
