Appearance:
white or light yellow free flowing powder, odorless, tasteless, non-toxic, hygroscopic. Soluble in water, transparent colloid, in neutral or slightly alkaline can form a high viscosity solution, insoluble in ethanol, ether, isopropanol, chloroform, acetone and other organic solutions, but soluble in ethanol or acetone solution containing 60% water. The specific gravity of 2% aqueous solution is 1.0088, stable to light, heat, and pH between 2 and 10, and does not precipitate or ferment when NaCl and CSCl2 are met. It has strong emulsifying ability to oil and wax, and is harmless to human body when eating. The temperature of discoloration is 190-205℃ and the temperature of carbonization is 235-243℃. The solubility of the product is related to the degree of substitution. If the degree of substitution is >1.2, it can be dissolved in organic solution. When the degree of substitution is 0.4-1.2, it is soluble in water and has good water retention. When the degree of substitution is less than 0.4, it can be dissolved in alkaline solution, and the surface tension of 2% aqueous solution is 71mN/N. The product can be divided into three levels according to the degree of polymerization N reflected by the viscosity. High viscosity type (2% aqueous solution, viscosity ≥ 1200mPa.s), medium viscosity type (2% aqueous solution, viscosity 300-800mPa.s); Low viscosity (2% aqueous solution, viscosity ≥1200mpa.s)
Packing, storage and precautions:
High pressure polypropylene woven bag coated with plastic, inner bag lined with PVC film, net weight 25.0kg each.
Storage attention: sealed, no sun and rain, moisture-proof.
