Sodium tripolyphosphate is mainly used as auxiliaries for synthetic detergents in the industry. It is an indispensable and excellent auxiliaries. It not only improves the decontamination effect of detergents and cleans our living environment, but also can be used for mining. , petroleum, paper, metallurgy and water treatment. Its main functions are as follows:
1. It has the property of chelating hard metal ions: Hard metal ions are usually contained in the washing water we usually use, and they will react with the active substances in the detergent to form metal salts. This not only increases the amount of detergent used, but also darkens the color of the items after washing. This property of sodium tripolyphosphate can eliminate these adverse effects of metal salts.
2. Can promote peptization, emulsification and dispersion: Sodium tripolyphosphate has a peptizing effect on proteins in human secretions, and can also promote the emulsification of fatty substances, and has a dispersion and suspension effect on solid particles such as sand and dust in the outside world. .
3. Has a large alkaline buffering effect: As an auxiliary agent for synthetic detergents, sodium tripolyphosphate can maintain the pH value of the detergent at about 8.4, which can promote the removal of acidic dirt.
4. Keep it dry: In a high humidity environment, powdered synthetic detergents tend to appear in pieces, which brings inconvenience during use. Sodium tripolyphosphate can form a dry hexahydrate product after absorbing water, which can effectively prevent the phenomenon of agglomeration, thus keeping the powdery synthetic detergent dry.
