Problems solved by technology

[0002] Existing detergents are mainly divided into two types: phosphorus-containing and non-phosphorus. The main component of phosphorus-containing detergents is sodium tripolyphosphate. Although it has a good cleaning effect, it is easy to make the water rich in phosphorus, and its use has gradually been restricted.
The builders used in phosphorus-free detergents are mainly 4A zeolite, layered disilicate, etc., because their adsorption capacity cannot be compared with sodium tripolyphosphate, so the washing effect is not very ideal. To solve this problem, manufacturers often use A large number of additives are added to phosphorus-free washing powder, such as the use of fluorescent whitening agents, etc. The use of these additives will have adverse effects on the human body and the environment

Abstract

There is a kind of oxygenic detergent and the manufacturing method, which is is mainly made up of bleacher and aid detergent. Its characters lie in that the bleacher is one of sodium superborate, sodium supercarbonate and painted sodium supercarbonate or compound with more of them; aid detergent is one of sodium carbonate, sodium sulfate and sodium silicate or compound with more of them; the invention still may add alkaline protease, anti-dirt sediment agent, bleaching and activating agent. The manufacturing method is: bleacher, aid-detergent, alkaline protease, anti-dirt sediment agent, bleaching and activating agent are put into mixing machine, then the machine starts to mix them about 5-25 minutes, after that, it gives out materials, oxygen detergent is obtained.
