  • Surface Sizing Agent GS

    Surface Sizing Agent GS

    Physical and chemical properties: Main component Cationic Styrene acrylate copolymer Appearance: Light yellow or brown dispersion Solid content (%) 30±1% PH value (25 ℃) 2.0-4.0 Viscosity (25 ℃) <50cp Function: Provide water resistance of paper, and the action of starch on the surface can prevent paper from returning to moisture to stabilize the strength index of paper. Performance: 1. GS should be used in sizing press equipment together with surface starch; 2. When using was...
  • LBA3000L α~Biological amylase

    LBA3000L α~Biological amylase

    α~Amylase lba3000l was purified from Bacillus subtilis by deep culture and extraction. This product is a liquid enzyme preparation. It is a kind of endoamylase, which can hydrolyze starch, glycogen and their degradation products randomly α~ 1.4 glycosidic bond makes the viscosity of colloidal starch solution decrease rapidly, resulting in soluble dextrin and maltose. Excessive hydrolysis can produce a small amount of glucose and maltose. This product is also widely used in starch, sugar, alcohol, Baijiu, beer, MSG, soy sauce, pharmaceutical, textile, printing and dyeing desizing.
