What is the production mode of sodium metasilicate in pentahydrate

Release date:2018-06-20 Author: Click:

 

The preparation method of sodium metasilicate in pentahydrate is characterized in that sodium metasilicate in pentahydrate is a key washing agent to replace sodium tripolyphosphate. The addition of sodium metasilicate in pentahydrate can lower the phosphorus and cost of the washing agent and improve the decontamination ability. This innovation takes the paohua alkali and liquid alkali as the important raw material, USES the simple production process, can produce the product which reaches the United States, Britain and Japan standard request, and the cost is low, not agglomeration, very very has the market power.



The production method of sodium metasilicate in pentahydrate is that quartz powder with 90% or more silicon content and liquid alkali with 38-80% sodium content are used as the substrate materials.



This invention reference compound high silicon content of quartz powder and liquid alkali is because the raw material, under the heat pressure lining video, directly after the cooling crystallization, not demand to evaporate moisture, implements the step to get five water production process of sodium metasilicate, citing high levels of sodium compound liquid alkali, get the goods directly in the lining video material filling water. The innovation not only saves production cost greatly, but also eliminates environmental pollution and has good financial and social benefits.
