Hoʻohana
1,4-Butanediol (BDO)he mea maka kemika organik koʻikoʻi me nā ʻano hana like ʻole. ʻO nā ala noi nui penei:
Ka hana ʻana i ka huahana polyester
- No ka hana ʻana o ka polybutylene terephthalate (PBT): He ʻano hana ʻenekinia polyester thermoplastic maikaʻi loa ka PBT. Loaʻa iā ia nā waiwai mechanical maikaʻi, ke kūpaʻa maikaʻi loa i ka palaho kemika, ka insulation uila maikaʻi loa, a me ke kūpaʻa dimensional ikaika. Hoʻohana nui ʻia ia ma ke kahua o nā mea uila a me nā mīkini uila e hana i nā hale a me nā mea hoʻohui uila like ʻole. ʻO kekahi mau ʻāpana i ka ʻoihana kaʻa, e like me nā lima puka kaʻa a me nā bumpers, hana pinepine ʻia me ka hoʻohana ʻana i nā mea PBT.
- No ka hana ʻana o ka polyurethane thermoplastic (TPU): Hoʻohui ʻo TPU i ka elasticity kiʻekiʻe o ka rubber me ka maʻalahi o ka hana ʻana o ka plastic. He kūpaʻa ia i ke kapa, kūpaʻa i ka ʻaila, a kūpaʻa i ke anu. Hoʻohana pinepine ʻia ia e hana i nā kapuaʻi kāmaʻa, nā paipu, nā ʻūpā uea a me nā kaula, nā kāʻei conveyor ʻoihana, a pēlā aku. He mea pono ʻole ka 1,4-Butanediol no ka synthesis o TPU, e hāʻawi ana i ka huahana me ka maʻalahi maikaʻi a me nā waiwai tensile.
Hana ʻana o γ-butyrolactone a me N-methylpyrrolidone (NMP)
- γ-butyrolactone: He mea hoʻoheheʻe maikaʻi loa ia me ka hoʻoheheʻe ikaika, loaʻa ka hopena hoʻoheheʻe maikaʻi ma nā hui organik a me nā polymers he nui. Hoʻohana nui ʻia ia i nā ʻoihana uhi, ʻīnika, a me ka paʻi a me ka hoʻoluʻu ʻana. ʻO ia hoʻi ka mea hoʻomaka no ka synthesis o nā mea ʻala like ʻole a me nā mea waena lāʻau lapaʻau, kahi e hiki ai ke loaʻa nā kemika maikaʻi like ʻole me nā ʻano a me nā hana kūikawā.
- N-methylpyrrolidone: He mea hoʻoheheʻe aprotic polar ia, e hōʻike ana i ka hiki ke hoʻoheheʻe maikaʻi loa no nā mea organik, inorganic, a me polymer he nui. He mea koʻikoʻi loa ia i ka hana ʻana o nā pila lithium, i hoʻohana ʻia e hoʻoheheʻe i nā mea hoʻopaʻa, nā mea hana electrode, a pēlā aku. He mau noi koʻikoʻi nō hoʻi ia i ka hana pesticide, ka hoʻomaʻemaʻe uila, a me nā kaʻina hana unuhi a hoʻokaʻawale.
No ka hana ʻana o ka tetrahydrofuran (THF): ʻO Tetrahydrofuran kahi mea hoʻoheheʻe maikaʻi loa i hoʻohana nui ʻia, nona ka solubility maikaʻi no nā hui organik kūlohelohe a me synthetic. I loko o nā keʻena hoʻokolohua synthesis organik a me nā ʻōnaehana hopena o ka hana kemika, hoʻohana pinepine ʻia ia ma ke ʻano he mea hoʻoheheʻe e hoʻolaha i nā hopena. Eia kekahi, ʻo ia kekahi mea maka no ka synthesis o polytetrahydrofuran (PTMEG). Hoʻohana ʻia ka PTMEG e hana i nā olonā spandex a me nā elastomers polyurethane, e hāʻawi ana i kahi kumu mea elastic kiʻekiʻe no ka lole, nā lole haʻuki kiʻekiʻe, a me nā ʻoihana ʻē aʻe.
Nā noi ma ke kahua lapaʻau: Hiki ke hoʻohana ʻia ʻo 1,4-Butanediol ma ke ʻano he mea hana lāʻau lapaʻau waena e komo i ka synthesis o kekahi mau molekala lāʻau. No ka laʻana, i nā ʻanuʻu synthesis o kekahi mau lāʻau steroid a me nā antibiotics, hoʻohana ʻia kāna hana kemika e kūkulu a hoʻololi i nā ʻano o nā molekala lāʻau, e hoʻomaʻamaʻa ana i ka noiʻi, ka hoʻomohala ʻana, a me ka hana ʻana i nā lāʻau hou.
ʻŌpala a me ka Hoʻouna ʻana
25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
