1,2-Propylene Glycol CAS NO.57-55-6
Huahana Huahana
- 1,2 Propylene glycol he mea waena o ka bactericide difenoconazole a he mea maka nui no ka polyester unsaturated, epoxy resin, a me ka resin polyurethane. ʻO ka nui o kēia ʻāpana e pili ana i ka 45% o ka nui o ka hoʻohana ʻana o 1,2 propylene glycol. Hoʻohana nui ʻia kēia poly Ester unsaturated i ka uhi ʻili a me nā plastic i hoʻoikaika ʻia. ʻO 1,2 propylene glycol he viscosity maikaʻi a me ka hygroscopicity, a ʻaʻohe mea ʻawaʻawa, no laila ua hoʻohana nui ʻia e like me ka moisture absorbent, antifreeze, lubricant a me ka solvent i ka meaʻai, lāʻau lapaʻau a me nā ʻoihana hoʻonaninani. I ka ʻoihana meaʻai, hoʻohana nui ʻia e like me ka emulsifier meaʻai; i ka manawa like he mea hoʻoheheʻe maikaʻi loa ia no nā mea hoʻonani a me nā puaʻa.
- ʻO ke kaʻina hana o ka 1,2 propylene glycol no ke kahua ʻenehana o ka hoʻokaʻawale kemika. Hoʻohana kēia kaʻina hana i nā hiʻohiʻona i maʻalahi ka paʻakai mineral acid e crystallize, ʻoiai ʻaʻole maʻalahi nā paʻakai ʻakika organik i loko o ka propylene glycol fermentation broth. Hoʻohui ʻia ka nui kūpono o ka waikawa inorganic i ka broth fermentation propylene glycol e hoʻololi i nā paʻakai ʻakika organik i loko o ka hupa fermentation me nā waikawa organik. Hoʻokumu ʻia ka paʻakai mineral acid; ʻO ka hupa fermentation ka paʻakai, no laila e hoʻokaʻawale ʻia ka paʻakai mineral acid, a hoʻokaʻawale ʻia mai ka broth fermentation; ʻO ka broth fermentation concentrated e lilo i propylene glycol, succinic acid, lactic acid, acetic acid, glycerol a me 2,3-butane ʻO ka hui ʻana o ka waiʻona, ka distillation vacuum o ka hui e loaʻa nā huahana o kēlā me kēia ʻāpana. I ka ʻoihana lāʻau lapaʻau, hoʻohana pinepine ʻia ka propylene glycol ma ke ʻano he solvent, softener a excipient no ka hana ʻana i nā ʻano ʻaila a me nā ʻaila. Ma muli o kona kūpono maikaʻi me nā meaʻala likeʻole, hoʻohanaʻiaʻo ia ma keʻano he mea hoʻoheheʻe a me ka palupalu no nā mea hoʻonani. ʻO kahi hopena wai o propylene glycol kahi antifreeze maikaʻi.

- Ma keʻano he mea hoʻoheheʻe, hiki iā ia ke hoʻopau i nā meaʻai meaʻai i hikiʻole ke hoʻololi i ka wai e like me nā preservatives, pigments, antioxidants, etc., a laila hoʻohui i ka meaʻai; he hygroscopicity ikaika, a he moisturizing a anti-freezing hopena ma ka ai.
- Ma keʻano he mea lawe lāʻau a me ka lāʻau lapaʻau granular. Hiki ke hoʻohana ʻia e like me ka humectant, softener, solvent, etc.
- I ka ʻoihana paka, hiki ke hoʻohana ʻia e like me ka ʻono paka, ka moisturizer paka, preservative, etc.
- I ka ʻoihana meaʻai, hoʻohana ʻia ia e like me ka solvent no nā mea ʻono, kala meaʻai, nā mea hoʻomaʻemaʻe ʻai meaʻai, a me nā mea ʻai anti-sticking agents.
