newsBari muyi koyi game da Tween 80 (wanda aka fi sani da Tween 80 ko polysorbate 80) da Tween 20 (wanda aka fi sani da Tween 20) ta hanyoyi guda uku
1。 Kirkirar Tween 80 ya dogara ne akan polymerization na deaturated sorbitol monooleate da ethylene oxide. Kira na tsakanin 20: cakuda polyethylene glycol da sashin polyethylene glycol. Tsakanin 80 wani nau'i ne na polyol nonionic surfactant, wanda aka saba amfani dashi polysorbate. Ana amfani dashi ko'ina cikin ruwa, tsayayyen tsayayye da tsayayyen shiri, kamar su O / W emulsifier, solubilizer, wetting agent, dispersant da stabilizer.
2. Tsakanin 20 yana amfani da: don tanƙwasawar diski da ethylene oxide, saboda ƙwayoyinta suna da ƙarin rukunin polyoxyethylene na hydrophilic, don haka yana da ƙarfi mai ƙarfi, kamar yadda ba mai amfani da ionic. Ana amfani dashi mafi yawa azaman O-W emulsifier, ana iya amfani dashi tare da alkyl sulfate goma sha biyu ko emulsifier iri iri don inganta zaman lafiyar emulsion. Hakanan za'a iya amfani dashi azaman solubilizer don wasu ƙwayoyi. Halin Tween 80: ƙimar peroxide na Tween 80 bai fi 10 ba, wanda yake rawaya ne mai haske zuwa ruwan lemo mai ɗanɗano; yana da ɗan wari. Tasteanɗan ɗanɗano mai ɗanɗano, akwai jin dumi. Yana narkewa cikin ruwa, ethanol, methanol ko ethyl acetate, amma mai narkewa cikin mai ma'adinai.
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.
