surface sizing agent

A product introduction.... Surface sizing agent is to promote industry or cardboard surface strength, water resistance, stiffness, strength and smoothness of paper printing properties and surface finishing of a product. This product is good because the affinity with fiber surface film, glue of hydrophobic, and have strong ability to enhance the ring crush all functional monomer synergy with excellent properties after. Ii. The product performance and characteristics In the process of glue adopts, product and fiber and keep good affinity with starch, adding additives, dyes and other good compatibility and synergies, Responding to significantly improve the corrugated board boxes of paper and water resistance and compressive strength, The paper adopts improve surface strength and water resistance, replace intracytoplasmic glue, glue, the paper thoroughly changed the paper FanChao back glue phenomenon, Adopts excellent mechanical stability, produced in the process of operation, not another bubbles add xiaopaoji, This product adopts surface glue with starch with usage, low cost, glue notable effect etc, and can completely replace the imported products. 3. Product application This product can effectively with glue starch crosslinking, film, improve paper printing surface strength and glue, also can reduce cost, but also can improve the production efficiency. For cases of corrugated paperboard and surface sizing, replace intracytoplasmic sizing agent can improve the water resistance and compressive strength. 4. Product technology index Appearance: ivory to hazel milky liquid Solid: 20 ± 0.5% PH: 4.0 ± 0.5 Viscosity (25 degrees Celsius) : 8cps 5. Use methods 1 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 2. PH adjustment, starch gelatinization glue with aluminium after completely solution as PH in 3.0. (general tons with aluminium liquid 6-8 kg), 3 the gluing additives used to join Responding to join dosage: according to the pulp and paper tons of different dosage 0.5-250 kg. Responding to join method: A, intermittent, join the starch gelatinization diluted liquid temperature below 60 degrees Celsius, measuring good sizing agent, and start to stir, agitate backup, B, continuous to join, according to the paper machine speed calculation according to the production output and consumption of starch calculation tons of paper glue and additives on the flow of starch adhesive before the machine with metering pump for joining. Continuous adding requirements of starch glue tank level automatic control. 6. Note Responding to starch pasting must fully, uniform, starch liquid viscosity indexes of concentration, stable, Responding to use, add vitriolic starch. Responding to control starch liquid temperature drop to 60 degrees Celsius, just can join our product, continuous join temperature can relax appropriately, Adopts the reasonable control starch liquid concentration, viscosity and PH indicators should be stable, Responding to avoid and instead of ions in the same position, while auxiliaries combination, Adopts products do not contain harmful components in contact with the skin, if carelessly, immediately the eyes or rinse it. 7. Packaging and storage Using 200kg or 1000kg second-ranking polyethylene plastic packaging barrels Adopts products should be stored in a 5-30 degrees Celsius (dry and ventilated, shade, pay attention to prevent freezing and friends? In accordance with the second-ranking storage conditions circumstance, products are valid for 3 months.
