Chemical properties
Appearance: white or off-white powder.
The particle size mesh pass rate is greater than the mesh pass rate. Special specifications of particle size ~ mesh.
, carbonization temperature ℃
, apparent density / (usually around the specific gravity.
, discoloration temperature ℃
, surface tension aqueous solution is /
, solubility soluble in water And some solvents, such as ethanol/water, propanol/water in appropriate proportions. The aqueous solution has surface activity. It has high transparency and stable performance. Products of different specifications have different gel temperatures. The solubility changes with the viscosity. The lower the viscosity, the solubility The larger the value, the different specifications have certain differences in performance, and the dissolution in water is not affected by the value.
As the methoxy group content decreases, the gel point increases, the water solubility decreases, and the surface activity also decreases.
>, It also has the characteristics of thickening ability, salt resistance, low ash powder, stability, water retention, dimensional stability, excellent film-forming properties, and wide range of enzyme resistance, dispersion and adhesion. Molecular formula and molecular weight< br/>Usage introduction
In the construction industry, it is used as a water retaining agent and retardant for cement mortar to make the mortar pumpable. It is used as a binder in plaster slurry, gypsum material, putty powder or other building materials to improve the spreadability and extend the Operable time. Used as a pasting tile, marble, plastic decoration, pasting enhancer, and can also reduce the amount of cement. The water retention performance prevents the slurry from cracking due to drying too quickly after application, and enhances the strength after hardening. < br/>Ceramic manufacturing industry is widely used as a binder in the manufacture of ceramic products.
Coating industry As a thickener, dispersant and stabilizer in the coating industry, it has good compatibility in water or organic solvents. As Paint remover.
Ink printing is used as a thickener, dispersant and stabilizer in the ink industry, and has good compatibility in water or organic solvents.
Plastics are used as mold release agents, softeners, Lubricant, etc.
It is used as a dispersant in the production of polyvinyl chloride and is the main additive in suspension polymerization preparation.
Others, this product is also widely used in leather, paper products industry, fruit and vegetable preservation and textiles Industry, etc.
Pharmaceutical industry coating materials, film materials, rate-controlling polymer materials, stabilizers, suspending agents, tablets, adhesives, and thickeners for sustained-release preparations
