Surface Sizing Agent ‘sUse methods

Surface Sizing Agent ‘sUse methods. First the starch pasting, oxidation process.Responding to starch pasting process:Will starch pasting tank into half pot (70%) water, and then the blender filled tank slowly, slowly starch through steam heating to 60 degrees Celsius, starch gelatinization, begin to slightly stick-slip emulsion. Stop and join after 15 minutes, stirring amino acid. 50 ° c, heat temperature for 10 minutes, then slowly open the oxidation reaction heat, steam valve continued for pasting temperature, reaction process about 85-90 degrees to transparent plastic starch emulsion liquid. Close valve, continue to stir, steam heat preservation 20 minutes. Add water dilute, temperature in 65-70 ° c.Adopts feeding process ratio:Starch: sulfuric acid amine = 10:4.Responding to starch pasting concentration of 10-15%, 8-12. Use concentration
