Export grade hydroxypropyl methyl cellulose HPMC - hydroxypropyl methyl cellulose
First, the main use:
1.In building construction, hydroxypropyl methylcellulose is mainly used in exterior wall insulation systems, thermal insulation mortars, decorative mortars, masonry mortars, self-leveling mortars, etc. It is suitable for concentrated dry mixing and pre-mixed mortar, which has thickening, water retention, film formation and cohesiveness, which can improve construction and slip resistance, and improve the pumping performance of slurry.
2.In decorative construction, hydroxypropyl methylcellulose is used as an adhesive tile, marble, etc., with high viscosity and strength, and can also reduce the amount of cement.
3.It is used for whitewashing gypsum, water-resistant putty, bonded gypsum, caulking mortar cement-based plaster, etc., which can significantly improve its water retention and bonding strength, and has the characteristics of good workability and no cracking.
4.Used as a thickener in the coating industry, hydroxypropyl methyl cellulose can make the coating bright and delicate, without depowdering, and improve its leveling.
5.It is used as a suspending agent and binder in ceramic glaze to make the pigment evenly dispersed in the glaze.
6.It is mainly used in the industry as a suspension polymer dispersant, due to the excellent dispersion and glue retention ability of hydroxypropyl methyl cellulose, it can obtain products with regular particles, concentrated particle size distribution, appropriate specific gravity and excellent processing performance.
7.In other industries and departments, such as petrochemical, construction, printing and dyeing, tobacco, daily chemical, papermaking, leather, agriculture and forestry, it is widely used as thickener, binder, water retention agent, film forming agent, emulsifier, excipient, etc.
Second, technical indicators:
3. How to use:
Rapid dissolution: Hydroxypropyl methylcellulose HPMC is soluble in water and some organic solvents under constant stirring, if it is dissolved quickly, the following methods are recommended:
1.To make porridge-like mother liquor: first make HPMC into a higher concentration of porridge-like mother liquor (the method is the same as above to slurry), and then add cold water and continue to stir until it is transparent.
2.Dry blending: Because HPMC has good compatibility, it can be easily used with cement, stone slip powder, pigment and other dry blends, and achieve the desired effect.
Fourth, the dissolution method:
This product is easily soluble in cold water and can also be quickly dissolved using the following methods:
1. Add cellulose slowly and evenly at room temperature, and stir constantly during the addition process until a transparent solution is formed.
2. Dry blending: In case of other powders, they should be fully mixed with the powder and then add water, so that they can be dissolved quickly and will not agglomerate.
3. Organic solvent wetting method: First, the product is dispersed into an organic solvent or moistened with an organic solvent, and then added to cold water or added to cold water, which can be well dissolved, and the organic solvent can be ethanol, ethylene glycol, etc.
Fifth, the field of application.
Thermal insulation mortar, tile adhesive, grout, stucco plaster, plastering, masonry mortar;
Coating thickeners, dispersants and stabilizers;
Inks as thickeners, dispersants and stabilizers;
Release agents, softeners, lubricants for plastic molding;
Cement, gypsum secondary products;
Shampoo, dish soap.
Six: Packing: 25kg composite packaging bag packaging, packed with PVC plastic bags, palletized (one ton 1.).9 cubic meters).
7. Storage and transportation:
Rainproof and sunproof, fireproof and moisture-proof, airtight and ventilated storage, and transported as non-dangerous goods.
