newsMe ako tatou mo te Tiwa 80 (e mohiotia ana ko Tantara 80 ko te polysorbate 80 ranei) me te Taangata 20 (e mohiotia ana ko Runga i te 20) i roto i nga momo momo e toru.
1。 Ko te whakahiatotanga o te takiwa o te 80 e hangai ana ki te polymerization o te horahanga o te sorbitol monooleate me te ethylene oxide. Te hangahanga o waenga 20: te ranunga o te polyethylene glycol me tetahi waahanga o te polyethylene glycol. Ko te takawaenga o te 80 he momo polyact nonionic surfactant, e whakamahia whānuitia ana i te polysorbate. Kei te whakamahia whānuitia i roto i te whakarite waipiro, totoka-totoka, totoka hoki, penei i te O / W emulsifier, solubilizer, wetting agent, dispersant me stabilizer.
2. Kei waenga i te 20 nga whakamahinga: mo te whakaheke i te kopae me te waikawa o te waikawa, na te mea he maha atu nga roopu polyoxyethylene hydrophilic, no reira he kaha te kaha o te hydrophilicity, hei horoi hopi-kore. Ka whakamahia hei O / W emulsifier, ka taea te whakamahi me te tekau ma rua alkyl sulfate momo emulsifier ranei hei whakapai ake i te pumau o te emulsion. Ka taea hoki te whakamahi hei whakarewa mo etahi raau taero. Pūāhua o Roto 80: ko te wariu peroxide o te takiwa o te 80 kaore i neke atu i te 10, he kowhai kowhai tena ki te waipiro karaka karaka; he paku haunga. He iti te kawa, he ahua mahana. He wairewa i roto i te wai, te etanol, te methanol te etyl acetate ranei, engari ka rewa i te hinu kohuke.
Characteristics of Tween 20: Tween 20 is a yellow or amber transparent oily liquid, with a special smell and weak bitter taste. The relative density is 1.01, boiling point & gt; 100 ° C, flash point 321 ° C, refractive index 1.472, viscosity (25 ° C) 0.25 ー 0.40 passec.
