Description

hpmc,hmpc

Shandong Chen Bang fine chemical industry to introduce advanced production equipment and technology, with the modernization of the cellulose ether and redispersible latex powder production line, and its strict quality control system and testing system and perfect service to ensure the site for users to provide satisfactory products. The leading products are hydroxypropyl methyl cellulose HPMC, hydroxyethyl cellulose HEC, hydroxypropyl starch ether HPS, redispersible emulsion powder series. Products are widely used in construction, chemical, coating, daily chemical, military and other fields, respectively, made of film agent, adhesive, dispersant, stabilizer, thickener and so on.

Hydroxypropyl methyl cellulose, hydroxypropyl cellulose, cellulose, hydroxypropyl methyl ether, is made of highly pure cotton cellulose as raw material, using lye at 35-40 DEG C treatment for half an hour, squeezing, crushing cellulose at 35 DEG C, due to aging, the alkali fiber flat income average degree of polymerization in a desired range. Adding alkali fiber into the etherification kettle, adding propylene oxide and methyl chloride in turn, etherification 5h at 50-80 DEG C, and the pressure is about 1.8MPa. Then add the proper amount of hydrochloric acid and oxalic acid washing material in the hot water at 90 DEG C to enlarge the volume, then dehydrate the centrifuge and then wash it to neutral again and again.

Technical support for product use:

* this product in more than 85 DEG C above the water swelling, dispersing and dissolving of commonly used the following methods:

The total water requirement of 1/5-1/3 hot water, and stir the bentonite products, then add the remaining water, can be cold, even can add in ice water, stirring to control in the suitable temperature (10 DEG C), can be completely dissolved.

Dry mixing: in case of other powder matching, should be fully mixed with powder, and then add water, it will soon dissolve, will not be mass.

Organic solvent wetting method: first, the products are dispersed into an organic solvent or organic solvent is added into wet, cold water or cold water will be added, can be well dissolved in organic solvent, ethanol, ethylene glycol can be used.

Instant cold water law: in the container into the amount of tap water, slowly stirring gradually add HPMC, HPMC began to spread rapidly to the water, but no diffusion of dissolved, standing for a few minutes later, HPMC slowly dissolve, viscosity slowly up, to achieve the effect of.

Application field

Building industry

1, cement mortar: improve the dispersion of cement sand, greatly improve the plasticity of mortar and water retention, to prevent cracks have effect, can enhance the strength of cement.

2, ceramic tile cement: improve the plasticity of tile mortar, water retention, improve the adhesive force of ceramic tile, prevent powder.

3, asbestos and other refractory materials coating: as a suspension agent, liquidity improvement agent, but also to improve the adhesive force on the base.

4 gypsum coagulant slurry: improve water retention and processability, improve the adhesive force on the substrate.

5. Seam cement: added to the gypsum board used in the joint cement, improve flowability and water retention.

6, emulsion putty: improve resin emulsion based putty liquidity and water retention.

7, plaster: as a substitute for natural substances paste, can improve water retention and improve the same base rubber relay.

8, coating: as a latex coating plasticizer, to improve the coating and putty powder operation performance and improve liquidity.

9, spray paint: to prevent cement or latex Department spraying, have no material filling subsidence, and improve flow and spray pattern has good effect.

10, cement, gypsum two times products: as cement, asbestos and other water hard material extrusion molding adhesive use, improve liquidity, can get homogeneous molding.

11, fiber wall: because of the anti enzyme, anti bacterial effect, as a sand wall adhesive is effective.

12, other: can be used as thin sand, sand, mortar and sludge operated man's role (PC version) of the bubble retention agent.

chemical industry

1. Polymerization of vinyl chloride and vinylidene chloride: as a stabilizing agent in polymerization, a dispersant can be used with ethylene glycol (PVA) and hydroxypropyl cellulose (HPC) to control the distribution of particles and particles.

2, adhesive: as wallpaper adhesive, in place of starch, usually with vinyl acetate latex coating and use.

3, pesticide: added to pesticides, herbicides, can improve the adhesion effect when spraying.

4, latex: improve asphalt emulsion stabilizer, styrene butadiene rubber (SBR) latex thickening agent.

5: adhesive: as a pencil, crayon molding adhesive.

Cosmetics industry

1, shampoo: improve shampoo, detergent, cleaning agent viscosity and bubble stability.

2, toothpaste: improve the flow of toothpaste.

Kiln industry

1, electronic materials as electric ceramic vessels, pressure molding adhesive ferrite bauxite porcelain, with 1.2 - and propylene glycol.

2 glaze medicine: used as ceramic glaze medicine and enamel with, can improve the adhesion and processability.

3. Refractory mortar: added to refractory bricks, mortar or pouring furnace material, can improve plasticity and water retention.

Other industries

1, fiber as dye printing paste used in paints, dyes, boron soil, basic dyes, textile dyes, in addition, in the process of kapok corrugated, with thermosetting resin and use.

2, for the leather paper: carbon paper glue and oil processing, etc..

3: Leather: as the last lubrication or one-time adhesive used.

4. Water-based ink: added in water-based ink, ink, as thickening agent, film forming agent.

5: Tobacco: as a binder for recycled tobacco.

Packing: 25 kg / bag, paper plastic composite bag, lining protection.
