Hāʻawi hale hana CAS 110-63-4 1,4-Butanediol wai kala ʻole me ka maʻemaʻe kiʻekiʻe
Hoʻohana
Hoʻohana nui ʻia ka 1, 4-butanediol.MaʻAmelika Hui PūʻIa a meʻEulopa Komohana no ka hapa nui o ka hanaʻana o ka tetrahydrofuran, a ma hope o ka hanaʻana o γ-butanolactone a me polybutylene terephthalate,ʻo ka mea hope he mea hoʻomohala wikiwiki i nā plastics engineering;Hoʻohana ʻia ʻo 1, 4-butanediol ma ke ʻano he kaulahao a me ka polyester raw material no ka hana ʻana i nā elastomers polyurethane a me nā plastic polyurethane foam palupalu;ʻO nā esters o 1, 4-butanediol nā mea hoʻohui maikaʻi no cellulose, polyvinyl chloride, polyacrylates a me nā polyesters.1, 4-butanediol he hygroscopic flexibility maikaʻi, hiki ke hoʻohana ʻia e like me ka gelatin softener a me ka wai absorbent, cellophane a me nā mea lapaʻau ʻole-pepa ʻē aʻe.Hiki ke hoʻomākaukau ʻia ʻo N-methylpyrrolidone, N-vinyl pyrrolidone a me nā derivatives pyrrolidone ʻē aʻe, i hoʻohana ʻia i ka hoʻomākaukau ʻana i ka huaora B6, pesticides, herbicides a me nā ʻano ʻano mea hoʻoheheʻe, plasticizers, lubricants, humidifiers, softness, adhesives a me electroplating industry brightener.
He reagent no ka nānā ʻana i nā kemika;hoʻohana ʻia ma ke ʻano he hopena paʻa no ka chromatography kinoea.Hoʻohana ʻia e like me ka solvent, non-toxic antifreeze, food emulsifier, moisture absorbent, for organic synthesis.ʻOihana lapaʻau, ʻoihana meaʻai.

Nā Kūlana Waihona
Mālama ʻia i loko o kahi ʻoluʻolu, hoʻoheheʻe ʻia, waiho ʻia ma kahi mamao aku o ka hale.Loaʻa nā lako hana ahi a me nā ipu wai i hoʻopaʻa ʻia.Loaʻa nā pahu kila māmā, aluminika a keleawe paha.
E hoʻohana i ka aluminika, ke kila kila, ke kila a i ʻole nā pahu palaki a i ʻole nā mea hiki ke ahi no ka mālama ʻana a me ka lawe ʻana.Pono e hoʻopiha ʻia ke keʻena me kahi mahana kiʻekiʻe o 20 ° C me nā pahu a me nā paipu.
