高纯硫酸铝 |
高纯硫酸铝是一种白色晶体,其比重为1.69的。 如果开放于空气中很长时间,它可能会吸收水分和有硬的设置。 在86.5℃时,会变成脱水。 它易溶于水,酸,碱,不溶于醇。 其水溶液呈酸性。 在530℃心肠,它会分解。 当温度升高到860℃时,将结束分解。 如果分解R-Al2O4的最终产品。 在水解过程中的期间,高纯度硫酸铝会产生碱的盐,然后氢氧化铝。 |

Aluminium Sulphate |
CAS: 10043-01-3 |
Aluminum Sulfate –for paper making |
Molecular Formula: Al2 (SO4) 3 XH2O |
Properties: It is white or gray flake, particle or massive crystallization. Apt to cake after moisture absorption when laid in air for a long time. A little green because of Fe2+, yellow when Fe2+ is oxided to Fe3+. Soluble in water easily, and water solution is acid. |
Use: Used with saponified rosin as paper strength enhancing binder to improve waterproof property. Also can be used in printing and dyeing, leather, color agentia and wood trust proof. |
Packing: In 25kg or 50kg woven bags with inner film. |

High-purity Aluminum Sulfate |
High-purity aluminum sulfate is a kind of white crystal whose specific gravity is 1.69. If open to the air for a long time, it might absorb moisture and have hard settings. Under 86.5℃, it will become dehydrated. It is soluble in water, acid and alkali, insoluble in alcohol. Its aqueous solution is acid. Hearted under 530℃, it will decompose. When the temperature increases to 860℃, it will end decomposing. The end product of decomposition if r-Al2O4. During the period of hydrolysis, high-purity aluminum sulfate will produce alkali salt and then aluminium hydroxide. |
