Ka whakamahia te propylene glycol mo nga tono rite ki etahi atu glycols.
Ko te propylene glycol he rauemi mata nui mo te polyester haunga, te kapia epoxy, me te kapia polyurethane.Ko te nui o te whakamahi i tenei waahi mo te 45% o te paunga katoa o te propylene glycol.Ka whakamahia nuitia taua polyester haunga mo nga kirihou whakakaha me te paninga mata.He tino pai te propylene glycol i roto i te viscosity me te hygroscopicity me te kore paitini, no reira ka whakamahia nuitia hei kaihoko hygroscopic, antifreeze, lubricants me te whakarewa i roto i te ahumahi kai, ho'oraa me te Paku.I roto i te ahumahi kai, tauhohe propylene glycol ki te waikawa ngako ki te hoatu hākawa propylene o waikawa ngako, me te te nuinga whakamahia rite emulsifier kai;Ko te propylene glycol he whakarewa pai mo nga mea kakara me nga poaka.Ko te propylene glycol te nuinga o te wa e whakamahia ana hei whakarewa, hei whakangawari, hei awhina, me etahi atu i roto i te umanga rongoa mo te hanga momo momo hinu me te salves.Ka whakamahia ano te propylene glycol hei whakarewa me te whakangawari mo te whakapaipai na te mea he pai te whakarewatanga o tetahi ki tetahi me nga momo mea kakara.Ka whakamahia ano hoki te propylene glycol hei kaiwhakamakuku tupeka, hei taputapu antifungal, hei whakahinuhinu taputapu tukatuka kai me te whakarewa mo te waituhi tohu kai.Ko te wairewa wai o te propylene glycol he kaihoko whakatio whai hua.
I te taha o te wai, ko te propylene glycol te waka kawe makuku e whakamahia ana i roto i nga hanganga whakapaipai.He pai ake te uru o te kiri i te glycerin, a ka hoatu he ahua pai ki te iti ake o te hinu i te glycerin.Ka whakamahia te propylene glycol hei humectant na te mea ka mimiti te wai mai i te hau.Ka mahi ano hei whakarewa mo nga anti-oxidants me nga kaitiaki.I tua atu, he taonga tiaki ki te huakita me te harore ina whakamahia ki te 16 paiheneti teitei ake ranei.He awangawanga kei te whakapataritari te propylene glycol ki nga kukū teitei, ahakoa te ahua he tino haumaru ki nga taumata whakamahi i raro i te 5 ōrau.
Ko te Propylene Glycol he whakangao me te wairewa kakara he waipiro polyhydric (polyol).he wai maramara, he wai kakao me te tino memehatanga i roto i te wai i te 20°c me te pai o te whakarewa hinu.ka mahi hei humectant, pera i te glycerol me te sorbitol, hei pupuri i te makuku me te kakano e hiahiatia ana i roto i nga kai penei i te kokonati kua kowhatu me te hukapapa.ka mahi hei whakarewa mo nga reka me nga tae e kore e rewa ki te wai.ka whakamahia ano ki nga inu me te monamona.
