Kupereka kwa Factory CAS 110-63-4 1,4-Butanediol Colourless Liquid yokhala ndi Kuyera Kwambiri
Kugwiritsa ntchito
1, 4-butanediol imagwiritsidwa ntchito kwambiri.Ku United States ndi kumadzulo kwa Ulaya kwa zaka zoposa theka la kupanga tetrahydrofuran, kutsatiridwa ndi kupanga γ-butanolactone ndi polybutylene terephthalate, yotsirizirayi ndi mapulasitiki opangidwa mofulumira;1, 4-butanediol imagwiritsidwa ntchito ngati unyolo wowonjezera ndi poliyesitala yaiwisi yopanga ma polyurethane elastomers ndi mapulasitiki ofewa a thovu a polyurethane;Ma esters a 1, 4-butanediol ndi zowonjezera zabwino za cellulose, polyvinyl chloride, polyacrylates ndi polyesters.1, 4-butanediol ili ndi kusinthasintha kwabwino kwa hygroscopic, ingagwiritsidwe ntchito ngati chofewa cha gelatin ndi madzi otsekemera, cellophane ndi mankhwala ena omwe si a pepala.Angathenso kukonzekera N-methylpyrrolidone, N-vinyl pyrrolidone ndi zina zotumphukira pyrrolidone, komanso ntchito yokonza vitamini B6, mankhwala, herbicides ndi zosiyanasiyana ndondomeko solvents, plasticizers, lubricants, humidifiers, softness, zomatira ndi electroplating makampani brightener.
A reagent kwa kusanthula mankhwala;amagwiritsidwa ntchito ngati njira yoyima ya chromatography ya gasi.Amagwiritsidwa ntchito ngati zosungunulira, zopanda poizoni antifreeze, emulsifier chakudya, kuyamwa chinyezi, popanga organic synthesis.Pharmaceutical, food industry.

Zosungirako
Kusungidwa mu ozizira, mpweya wokwanira, malo yosungirako kutali ndi nyumba, anakhalapo.Zida zozimitsa moto ndi zotengera zamadzi zomata zoyenera zilipo.Zitsulo zocheperako, aluminiyamu kapena zotengera zamkuwa zilipo.
Gwiritsani ntchito aluminiyamu, chitsulo chosapanga dzimbiri, chitsulo kapena matanki apulasitiki kapena zinthu zoyaka moto posungira ndi kunyamula.Chipinda chokhala ndi kutentha kwakukulu kwa 20 ° C chiyenera kudzazidwa ndi zotengera ndi machubu.
