- 外观为白色或微黄色粉末。 级别为LR（实验室级），适用于高分子化学实验及絮凝效果测试。 不溶于冷水及醇，在碱性条件下加热至85–95℃可糊化形成稳定胶体。 包装规格为500g或25kg。
English description（英文原文，共 1432 字符）
Product Name:Cationic Starch
English Name:Cationic Starch
CAS No.:56780-58-6
Aliases:Starch 2-hydroxy-3-(trimethylammonio)propyl ether chloride, Hydroxypropyltrimethylammonium chloride starch, Quaternized starch
Physical Properties:White or slightly yellow powder. Produced by etherification modification of natural starch (corn, cassava, etc.), with positively charged quaternary ammonium groups on the molecular chain. Insoluble in cold water and alcohols; requires heating to 85–95°C under alkaline conditions to gelatinize and form a stable colloid.
Uses:Used as a papermaking additive: the positive charges adsorb negatively charged fibers, significantly improving paper strength, filler retention and drainage performance. In wastewater treatment, it acts as an organic flocculant that neutralizes negatively charged suspended particles and accelerates sedimentation. In textile sizing, it replaces traditional sizing agents to improve warp yarn abrasion resistance. The LR grade is commonly used in polymer chemistry experiments, flocculation performance tests or process development.
Technical Specifications:
White or slightly yellow powder.
LR (Laboratory Reagent) grade, suitable for polymer chemistry experiments and flocculation performance tests.
Insoluble in cold water and alcohols; gelatinizes at 85–95°C under alkaline conditions to form a stable colloid.
Available in packaging sizes of 500 g and 25 kg.
