Sodium Aluminate Cas 11138-49-1
Sodium aluminate is an important commercial papermaking additive about 20 to 30 years ago. It has many uses, such as helping to keep fine fibers and fillers, stabilizing buffering capacity in water treatment, and adjusting the pH of the water circulation system. The strength of the paper (ie, neutralizing the acidic components that cause the paper to age) increases the opacity of the paper.

1. Sodium Aluminate is a mordant, water softener, is the manufacture of zeolite, opal glass and soap, analytical reagents. It is also widely used in rubber, printing and dyeing, textile, and catalyst production.
2. Sodium Aluminate can be used as cement quick-setting agent in civil engineering. This product is mixed with water glass for plugging during construction. It can make cement quickly condense. It is an ideal additive for underground, rapid construction and fast curing of cement.
3. In the paper industry, the combination of sodium aluminate and aluminum sulfate is a good filler, which can improve the pressure characteristics, the distance control of the rubber and the new printing machine; in the papermaking process, it can make the pulp quick set. The role is to replace the new product of the gel; it can increase the whiteness of the paper, make the paper surface smooth and smooth, and be more fluent in writing; it can increase the weight of the paper, increase the hardness of the paper, and not penetrate the paper during writing. .
4. In water treatment, it can be used as a water purifying agent to reduce the hardness of water, reduce turbidity, accelerate the sedimentation of suspended solids, and improve the separation conditions to accelerate the precipitation of hard ions to the insoluble aluminum hydroxide. Has a strong affinity, this property is used to treat boiler water in order to obtain very low silica impurity content and also used in the manufacture of coagulants to improve flocculation of clarified sewage with chalk, ferric chloride and polymeric media chemicals. The ability to flocculate the form of aluminum hydroxide accelerates the clarification process.
