2-Pyridinethione CAS NO.2637-34-5

Trimeric sodium phosphate detergent auxiliary agent is a kind of excellent properties, is one of the biggest component of detergent consumption during the production, it has four aspects: 1, chelation of heavy metal ions, heavy metal ions in the water in the washing process can be combined with the detergent molecules into insoluble metal salts, lower the washing ability, even completely.Therefore, detergent must be added to make the heavy metal ions in the water into harmless chelating agents.Sodium tripolyphosphate has a strong chelating effect on heavy metal ions, which can seal them up and eliminate their adverse effects on washing.In addition, it still can capture all sorts of metallic composition that the place in bilge contains, have the effect that makes bilge dissociate in catharsis process, can use as soap synergist and prevent soap grease to separate out and rise frost.2. Functions of deguming, emulsifying and dispersing dirt: dirt often contains human secretions (mainly protein and fat substances), as well as sands and dust from the outside world.Sodium tripolyphosphate has swelling and solubilizing effect on protein in dirt, so as to remove glue.Promote emulsification of fat;Dispersion of solid dirt;It has strong emulsifying effect on lubricating oil and fat and can be used to adjust the PH value of buffer soap.3, the role of detergents to prevent caking: powder synthetic detergents with hygroscopicity, such as stored in a place with high humidity, will occur caking phenomenon.Clotted detergents are extremely inconvenient to use.And sodium tripolyphosphate after water absorption of hexahydrate, with dry characteristics.When the detergent formula is used in large quantities, it can prevent the clotting phenomenon caused by moisture absorption, and maintain the dry and granular form of the synthetic detergent.4. It has a great alkaline buffering effect, keeping the pH value of the washing solution at about 9.4, which is conducive to the removal of acidic dirt.ChemicalBook
