| Eco_Friendly: | Yes | Item: | Complex Sodium Disilicate --best Stpp Substitute |
| Feature: | White Powder Or Granular | Chemical Formula: | Na2Si2O5 |
Sodium disilicate is a versatile chemical that can be used as a replacement for STPP in detergent powder making. The molecular formula of sodium disilicate is Na2Si2O5 and its CAS NO. is 13870-28-5. It is non-hazardous and does not have a UN number. Sodium disilicate comes in two types, namely Type 1 and Type 2, and has different appearances and bulk densities.
| Item | Type 1 | Type 2 |
|---|---|---|
| Appearance | White small granule, free flowing | White fine powder |
| Bulk density | 0.48g/cm3 | 0.68g/cm3 |
| 20FT Container | 13 mts | 19.5mts |
| 40HQ Container | 26 mts | 26-28 mts |
Sodium disilicate has excellent properties, including high calcium exchange ability (400mgCaCO3/gCSDS) which is better than STPP. It also has a pH buffering capacity, making it an ideal substitute for STPP. The product specification and COA of sodium disilicate is as follows:
| Item | Standard | Test result |
|---|---|---|
| Calcium exchange capacity | >=400mgCaCO3/gCSDS | 441.06 |
| Humidity | <=5% | 2.5 |
| pH value | <=12 | 11.27 |
| SiO2 | >=20% | 23.08 |
| Whiteness | >=80% | 87.99 |
| Bulk Density | 0.35-0.85 | Conform |
The product is packed in 25kgs plastic woven bags with an inner plastic film bag. Sodium disilicate is completely friendly to the environment, as it does not contain phosphates. It is free-flowing and easily blends with other chemicals. It does not easily absorb moisture in the air and does not become cake. Sodium disilicate can be used same as STPP in the producing process without any change in equipment, making it a popular choice for producing common or concentrate detergent powder.
The product has a shelf life of 12 months under proper storage conditions. It should be stored in cool, dry, and ventilated warehouses, away from incompatible chemicals such as oxidizing agents and acids. Sodium disilicate is a cost-effective and efficient alternative to STPP in detergent powder making.
The substance in question is capable of manifesting in two different physical forms: a white fine powder or a collection of small white particles. These appearances are distinguishable from one another and can be easily recognized by visual examination.
This substance can change its physical appearance depending on the environmental conditions, such as temperature and humidity levels. However, regardless of its form, its chemical properties and composition remain unchanged.
Complex Sodium Disilicate or Modified Sodium Disilicate is a commonly used ingredient in the production of detergent powder. Its application in the industry has been known to replace commonly used compounds such as sodium tripolyphosphate (STPP) or zeolite 4A. By using this compound, it is possible to enhance the cleaning power of detergents while also significantly reducing the environmental impact on water resources.
One of the distinct advantages of using Complex Sodium Disilicate or Modified Sodium Disilicate is its lower cost compared to other compounds used in the production of dishwashing detergents. It is readily available on the market, which makes it an attractive option for manufacturers seeking to reduce production costs. Despite its lower cost, it still delivers excellent performance compared to other conventional cleaning agents.
