Ukusetyenziswa
I-1,4-Butanediol (BDO)sisixhobo esibalulekileyo sekhemikhali yendalo esineendlela ezahlukeneyo zokusetyenziswa. Iindlela eziphambili zokusetyenziswa zezi zilandelayo:
Ukuveliswa kwemveliso ye-polyester
- Ukuze kwenziwe i-polybutylene terephthalate (PBT): I-PBT yiplastiki yobunjineli ye-polyester egqwesileyo ye-thermoplastic. Ineempawu ezintle zoomatshini, ukumelana nokugqwala kweekhemikhali okugqwesileyo, ubushushu obuhle bombane, kunye nozinzo oluqinileyo. Isetyenziswa kakhulu kwicandelo le-elektroniki kunye nezixhobo zombane ukwenza izindlu ezahlukeneyo zezixhobo zombane kunye nezihlanganisi. Ezinye iindawo kwishishini leemoto, ezifana neziphatho zeengcango zeemoto kunye neebhampa, nazo zivame ukuveliswa kusetyenziswa izixhobo ze-PBT.
- Kwimveliso ye-thermoplastic polyurethane (TPU): I-TPU idibanisa ukuthamba okuphezulu kwerabha kunye nokulula kokuyicubungula kweplastiki. Ayigugi, ayitshisi ioyile, kwaye ayibanda. Ihlala isetyenziselwa ukwenza izihlangu, iipayipi, iintambo kunye neekheyibhile, iibhanti zokuhambisa i-industrial, njl.njl. I-1,4-Butanediol sisixhobo esibalulekileyo sokwenziwa kwe-TPU, inika imveliso ukuguquguquka okuhle kunye neempawu zokuxinana.
Ukuveliswa kwe-γ-butyrolactone kunye ne-N-methylpyrrolidone (NMP)
- I-γ-butyrolactone: Sisinyibilikisi esibalaseleyo esinobushushu obuphezulu esinyibilikayo kakhulu, sinefuthe elihle lokunyibilikisa kwiikhompawundi ezininzi ze-organic kunye neepolymers. Sisetyenziswa kakhulu kumashishini okugquma, i-inki, kunye nokuprinta kunye nokudaya. Sikwayinto yokuqala yokwenza iziqholo ezahlukeneyo kunye nezinto ezidityanisiweyo zamayeza, apho iikhemikhali ezahlukeneyo ezintle ezinezakhiwo kunye nemisebenzi ekhethekileyo zinokufunyanwa khona kamva.
- I-N-methylpyrrolidone: Sisinyibilikisi se-polar aprotic, esibonisa amandla amahle okunyibilikisa izinto ezininzi ze-organic, inorganic, kunye ne-polymer ezinganyibilikiyo. Ibaluleke kakhulu ekuvelisweni kweebhetri ze-lithium, ezisetyenziselwa ukunyibilikisa izihlanganisi, izinto ezisebenzayo ze-electrode, njl. Ikwasetyenziswa kakhulu ekuvelisweni kwezibulali-zinambuzane, ukucoca nge-elektroniki, kunye neenkqubo zokukhupha nokwahlulahlula.
Kwi-synthesis ye-tetrahydrofuran (THF): I-Tetrahydrofuran sisinyibilikisi esibalaseleyo esisetyenziswa rhoqo, esinokunyibilika kakuhle kwiikhompawundi ezininzi zendalo nezenziweyo ze-organic. Kwiilabhoratri ze-organic synthesis kunye neenkqubo ze-reaction zemveliso yeekhemikhali, idla ngokusetyenziswa njengesinyibilikisi ukukhuthaza ii-reaction. Ukongeza, ikwayimathiriyeli yokwenza i-polytetrahydrofuran (PTMEG). I-PTMEG isetyenziselwa ukuvelisa ii-spandex fibers kunye ne-polyurethane elastomers, ibonelela ngesiseko sezinto ezithambileyo kakhulu kwimpahla yelaphu, iimpahla zemidlalo eziphezulu, kunye neminye imboni.
Ukusetyenziswa kwicandelo lezonyango: I-1,4-Butanediol ingasetyenziswa njengesixhobo sokudibanisa amayeza ukuze ithathe inxaxheba ekuhlanganisweni kwezinye iimolekyuli zamayeza. Umzekelo, kumanyathelo okwenziwa kwamanye amayeza e-steroid kunye nee-antibiotics, umsebenzi wayo weekhemikhali usetyenziselwa ukwakha nokuguqula izakhiwo zeemolekyuli zamayeza, okwenza kube lula uphando, uphuhliso, kunye nokuveliswa kwamayeza amatsha.
Ukupakishwa kunye nokuthunyelwa
25KG/Idrama okanye ngokweemfuno zomthengi.
Yeyokwempahla eqhelekileyo kwaye inokuhanjiswa ngolwandle nangomoya
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
