Ukunikezwa kwefekthri CAS 110-63-4 1,4-Butanediol Uketshezi Olungenambala Olungenabalabala
Ukusetshenziswa
1, 4-butanediol isetshenziswa kabanzi.E-United States naseNtshonalanga Yurophu ngaphezu kwengxenye yokukhiqizwa kwe-tetrahydrofuran, okulandelwa ukukhiqizwa kwe-γ-butanolactone kanye ne-polybutylene terephthalate, lesi sakamuva siyipulasitiki yobunjiniyela ethuthuka ngokushesha;I-1, i-4-butanediol isetshenziswa njenge-chain extender kanye ne-polyester impahla eluhlaza ekukhiqizeni ama-polyurethane elastomers namapulasitiki athambile e-polyurethane foam;I-esters ye-1, 4-butanediol iyizithasiselo ezinhle ze-cellulose, i-polyvinyl chloride, i-polyacrylates ne-polyester.I-1, i-4-butanediol inokuguquguquka okuhle kwe-hygroscopic, ingasetshenziswa njenge-gelatin softener kanye nokumunca amanzi, i-cellophane kanye ne-ejenti yokwelapha engeyona iphepha.Kungalungiswa futhi i-N-methylpyrrolidone, i-N-vinyl pyrrolidone nezinye izinto eziphuma ku-pyrrolidone, nazo ezisetshenziselwa ukulungiswa kwe-vitamin B6, izibulala-zinambuzane, ama-herbicides kanye nezinqubo ezihlukahlukene zokuncibilikisa, ama-plasticizers, ama-lubricant, ama-humidifiers, ukuthamba, ukunamathela kanye ne-electroplating industry brightener.
I-reagent yokuhlaziywa kwamakhemikhali;esetshenziswa njengesixazululo esimile se-gas chromatography.Isetshenziswa njenge-solvent, i-antifreeze engeyona enobuthi, i-emulsifier yokudla, imunca umswakama, ukuhlanganiswa kwezinto eziphilayo.Ezemithi, imboni yokudla.

Izimo Zokugcina
Igcinwe endaweni epholile, engenamoya, nendawo yokugcina kude nendlu, yaba khona.Imishini yokucisha umlilo kanye neziqukathi zamanzi ezivaliwe ezifanelekile ziyatholakala.Iziqukathi zensimbi, i-aluminium noma zethusi ezithambile ziyatholakala.
Sebenzisa i-aluminium, insimbi engagqwali, insimbi noma amathangi epulasitiki noma izinto ezivutha umlilo ukuze ulondoloze futhi uhambe.Igumbi elinokushisa okuphezulu kuka-20 ° C kufanele ligcwaliswe ngeziqukathi namashubhu.
