PAA polyacrylic Acid

详情

Polyacrylic acid PAA Polyacrylic Acid (PAA) CAS No. ********4 Structure 1, product performance PAA non-toxic, soluble in water, can be condensed in an alkaline- and middle-run under multiple conditions, without scaling. PAA can calcium carbonate, calcium sulfate salts of microcrystalline or sediment in the water does not spread precipitation, so as to achieve scale and purpose; PAA is a commonly used dispersant, other than for the circulating cooling water system as scale inhibition and dispersion agent use, but also widely used in papermaking and textile, printing and dyeing, ceramics, paints and other industries. Second, quality indicators in line with GB / T*********0 Project Index Appearance colorless or light yellow transparent liquid amber transparent liquid Solid content% ≥ *0.0 *0 Free monomer (CH2 = CH-COOH in order to count)% ≤ 0.*0 1.0 Density (*0 ℃) g/cm3 ≥ 1.*9 1.*0 PH (1% aqueous solution) ≤ 3.0 3.**4.5 Limit viscosity number (*0 ℃) dl / g 0.***0.*0 Factory can provide *0% of the polyacrylic acid for customer purchase. 3, the application scope and use PAA often associated with other water treatment agent composition of formulations used for power plants, chemical plants, chemical plants, refineries and air conditioning systems, cooling water system in the scale inhibition and dispersion agent. Specific formulation and dosage of PAA at the scene of the water quality of materials and equipment determined by the tests. PAA used alone, generally used concentration of 1 ~ *5mg / L. 4, packaging and storage PAA plastic barrel, *5kg. Stored indoors in the shade, storage period of *0 months. 5, security protection PAA eye and skin stimulation, but no acute toxicity.
