ʻO ka propylene glycol kahi mea hoʻohuihui me ke ʻano kemika C3H8O2, hiki ke hui ʻia me ka wai, ethanol a me nā mea hoʻoheheʻe ʻokoʻa like ʻole.ʻO ka propylene glycol kahi wai ʻeleʻele kala ʻole ma lalo o nā kūlana maʻamau, aneane ʻaʻohe ʻala a ʻono iki.ʻO 76.09 ka paona molekala.
ʻO ka Propylene Glycol nā waiwai a me ka paʻa
1. Ka wai wela.He hygroscopic a ʻaʻole e ʻino i ka metala.
2. He liʻiliʻi loa ka ʻona a me ka huhū.
3. Aia i loko o nā lau paka a me ka uahi.
Hoʻohana ʻia ʻo Propylene Glycol
Hiki ke hoʻohana ʻia ka propylene glycol ma ke ʻano he humectant i hui pū ʻia me ka glycerin a i ʻole sorbitol i loko o nā mea hoʻonaninani, nā niho niho a me ke kopa.I nā lauoho lauoho, hoʻohana ʻia ia ma ke ʻano he moisturizing a leveling agent, ma ke ʻano he antifreeze, a me ka cellophane, plasticizer a me ka ʻoihana lāʻau.
(1) He mea waiwai nui ka propylene glycol no nā polyesters unsaturated, resins epoxy, resins polyurethane, plasticizers, a me surfactants, a ʻo ka nui i hoʻohana ʻia ma kēia ʻano he 45% o ka pau ʻana o ka propylene glycol.No ka uhi ʻana o ka ʻili a me nā plastic i hoʻoikaika ʻia.
(2) He maikaʻi ka viscosity a me ka hygroscopicity propylene glycol, a ua hoʻohana nui ʻia e like me ka hygroscopic agent, antifreeze agent, lubricant a me ka solvent i ka meaʻai, pharmaceutical a me nā ʻoihana hoʻonaninani.
(3) I ka ʻoihana meaʻai, hoʻopili ʻia ka propylene glycol me nā mea momona e hana i ka propylene glycol fatty acid esters, i hoʻohana nui ʻia e like me nā emulsifiers meaʻai;ʻO propylene glycol kahi mea hoʻoheheʻe maikaʻi loa no nā condiments a me nā puaʻa.Ma muli o kona ʻona haʻahaʻa, hoʻohana ʻia ʻo ia i mea hoʻoheheʻe no nā mea ʻala a me nā kala meaʻai i ka ʻoihana meaʻai.
(4) Hoʻohana pinepine ʻia ka propylene glycol i ka ʻoihana lāʻau lapaʻau ma ke ʻano he solvent, softener a excipient no ka hana ʻana i nā mea ʻala like ʻole, a ma ke ʻano he mea hoʻoheheʻe no ka hui ʻana i nā mea hoʻohui, nā preservatives, nā ʻaila, nā huaora, penicillin, etc.
(5) No ka mea he maikaʻi ka hoʻoheheʻe ʻana o ka propylene glycol me nā ʻano ʻala like ʻole, hoʻohana ʻia ʻo ia e like me ka solvent a me ka palupalu no nā mea hoʻonaninani, etc.
(6) Hoʻohana pū ʻia ka propylene glycol ma ke ʻano he mea hoʻomaʻamaʻa paka, ka mea hoʻoheheʻe wai, ka ʻaila lubricating no nā mea hana meaʻai a me ka mea hoʻoheheʻe no ka ʻīnika māka meaʻai.
(7) ʻO nā ʻano wai o propylene glycol he mau mea antifreeze maikaʻi.Hoʻohana ʻia hoʻi e like me ka mea hoʻomaʻemaʻe paka, ka mea hoʻoheheʻe i ka maʻi, ka mālama ʻana i ka hua, antifreeze a me ka lawe wela, etc.
