Product name: Starch coating agent
Brand name: CHAMPRO- AT1080
Appearance: Viscous liquid
PH value: 9.5±1.5
Viscosity : 2000-10000cps
Description: CHAMPRO-AT1080 is a compound of high molecular weight grafting copolymers working together with CHAMPRO-AT8281 for native starch coating for papermaking system. After coating, the native starch consumption was reduced with the increasing paper strength property and COD reduction in the papermaking system. It achieves win-win among paper quality increase, production cost reduction and protecting environment.
Case Study:
1.Machine information:
Width: 2200 mm
Speed: 350m/min
Grammage: 300-600 g/m2
2.Results:





Internal bonding strength requirement: 450kg/cm min.
After coating, the starch consumption was reduced by 43% while maintaining the same paper strength property.






During the starch coating, the COD of mixed white water was decreasing obviously with the extension of time. The COD was decreased by 43% after 11 days of test.
