【APPLICATION】:

Complex Sodium Disilicate is widely used as STPP Substitute in detergent powder making such as concentrate detergent powder,
Ordinary detergent powder,
Phosphorus-free washing powder,
Low phosphorus detergent powder,
Metal-washing powder.
These detergent powders all can be washed by hand or washing machine.
It is mainly applied in high-tower spray dried technology.

【Conclusion】:

Complex Sodium Disilicate is the best in current phosphorus-free detergent builders, the function is almost same as STPP. It is the best replacement of STPP at present.
Complex Sodium Disilicate is completely friendly to each while STPP caused serious pollution.
Complex Sodium Disilicate has an excellent solubility in water, even cold water, better than STPP.
The price of Complex Sodium Disilicate is much lower than that of STPP
Complex Sodium Disilicate can be used same as STPP in producing process, without any change in equipment.
Complex Sodium Disilicate is the top cost performance non-phosphorus detergent which is widely used in leather washing and metal cleaning. It is based on national patent (the patent No:97107704.5) with exceeded capability.
The project has been completed and 50,000 tons per year production line.
Complex Sodium Disilicate reduce the phosphor pollution while driving entironment protection.
Complex Sodium Disilicate mainly used for washing powder, it accounts for it accounts for about 40% of the weight.
The global peolple need washing powder totally 15,000,000 tons, 50% by the use of sodium silicate compound calculated to be 3,000,000 tons in the second compound sodium silicate. In terms of per domestic use in washing powder to 1.5Kg calculated it would take a sodium silicate compound 720,000 tons.
Sodium Disilicate is included in the "1998 state-level Spark Program", "1999 state-level Torch Program" and "light of the strategic plan." by State Science and Technology.
