Colourless Clear 99.5% Liquid Ethyl Acetate Kwa Gulu Lamakampani
Kugwiritsa ntchito
Ethyl acetate ndi zosungunulira zabwino kwambiri zamafakitale ndipo zitha kugwiritsidwa ntchito mu ulusi wa nitrate, ulusi wa ethyl, mphira wa chlorinated ndi vinyl resin, cellulose acetate, cellulose butyl acetate ndi mphira wopangira, komanso mu inki zamadzimadzi za nitro fiber kwa opanga mafotokopi. Itha kugwiritsidwa ntchito ngati zosungunulira zomatira, zosungunulira utoto. Amagwiritsidwa ntchito ngati reagenti yowunikira, chinthu chokhazikika ndi zosungunulira pakuwunika kwa chromatographic. Mu mafakitale nsalu angagwiritsidwe ntchito ngati wothandizira kuyeretsa, mu makampani chakudya angagwiritsidwe ntchito ngati wapadera kusinthidwa mowa kukoma m'zigawo wothandizila, komanso ntchito ngati ndondomeko mankhwala ndi organic acid m'zigawo wothandizira. Ethyl acetate imagwiritsidwanso ntchito popanga utoto, mankhwala ndi zonunkhira.
Kusungirako kumakhala kotentha kwambiri ndipo kuyenera kukhala kokhala ndi mpweya wabwino komanso kouma, kupewa kutenthedwa ndi dzuwa ndi chinyezi. Ethyl acetate ikhoza kuipitsidwa ndi zoyaka, zotsekemera, ma asidi amphamvu ndi maziko, choncho ziyenera kulekanitsidwa ndi zinthu izi zikasungidwa ndikugwiritsidwa ntchito kuti zisawonongeke.
Zochitika za Ntchito
Ethyl acetate ili ndi ntchito zambiri. Zina zazikulu zopangira ndikugwiritsa ntchito ndizo:
1. Kupanga m'madera monga zodzoladzola, chisamaliro chaumwini ndi mafuta onunkhira.
2. Kupanga utoto, resin, zokutira ndi inki monga zosungunulira.
3. M'makampani opanga mankhwala, amatha kugwiritsidwa ntchito ngati zosungunulira komanso zotulutsa.
4. Amagwiritsidwa ntchito kwambiri m'makampani azakudya ndi zakumwa, mu mowa, vinyo, zakumwa, zonunkhira, madzi a zipatso ndi minda ina ngati zokometsera.
5. Nthawi zambiri amagwiritsidwa ntchito ngati zosungunulira m'ma laboratories ndi kupanga.
