工业级硼酸
物化性能:硼酸为白色粉末状结晶体,溶于水,水溶液呈酸性,熔点184-186。
质量标准:国标
硼酸产品介绍:
硼酸,为白色粉末状结晶或三斜轴面鳞片状光泽结晶,有滑腻手感,无臭味。溶于水、酒精、甘油、醚类及香精油中,水溶液呈弱酸性。大量用于玻璃(光学玻璃、耐酸玻璃、耐热玻璃、绝缘材料用玻璃纤维)工业,可以改善玻璃制品的耐热、透明性能,提高机械强度,缩短溶融时间。
用途:
硼酸在搪瓷、陶瓷业中,用以增强搪瓷产品的光泽和坚牢度,也是釉药和颜料的成份之一。在医药工业、冶金工业中作添加剂、助溶剂,特别是硼钢具有高硬度和良好的轧延性,以代替镍钢。硼酸有防腐性,可做防腐剂,如木材防腐。在金属焊接、皮革、照相等行业以及染料、耐热防火织物、人造宝石、电容器、化妆品的制造方面都用到它,还可作杀虫剂和催化剂用。在农业上作含硼微量元素肥料,对许多作物有肥效,可提高油菜籽的含油率。由硼酸可制造多种硼化物,广泛用于国防和其他工业部门和科研单位。
