Zowonekera zopanda utoto 99.5% madzi ethyl acetate kwa kalasi ya mafakitale
Kugwiritsa ntchito
Ethyl acetate ndi njira yabwino kwambiri yosungunulira ndipo itha kugwiritsidwa ntchito mu nitrate fiber, nthiti ya ethyl, cyyi lulluse acetate isteate inki ya vatiofiers. Itha kugwiritsidwa ntchito ngati zosungunulira zomata, utoto wochepa. Ntchito ngati zowunika, chinthu chokhazikika komanso zosungunulira kwa chromatographic kusanthula. M'makampani opanga malembawo angagwiritsidwe ntchito ngati wothandizira, mu makampani atha kugwiritsidwa ntchito ngati mankhwala apadera osinthika osinthika, komanso amagwiritsidwa ntchito ngati mankhwala opangira mankhwala ndi organic acgent. Ethyl acetate imagwiritsidwanso ntchito popanga utoto, mankhwala ndi zonunkhira.
Kusungidwa ndi firiji ndipo kuyenera kusungidwa ndi mpweya wabwino ndikuuma, pewani kuwonekera ndi dzuwa ndi chinyezi. Ethyl acetate imatha kuipitsidwa ndi zophatikiza, oxidants, zitsulo zamphamvu ndi zitsulo, chifukwa chake zimayenera kulekanitsidwa ndi zinthu izi zikasungidwa ndikugwiritsa ntchito popewa zoopsa.
Zolemba Zogwiritsira Ntchito
Aceyl acetate ali ndi ntchito zingapo. Madera ena akulu opanga ndi kugwiritsa ntchito amaphatikizapo:
1. Kupanga madera monga zodzoladzola, chisamaliro chaumwini ndi zonunkhira.
2. Kupanga utoto, umakulitsa, zokutira ndi inks, monga ma sol sol.
3. M'makampani opanga mankhwala, imatha kugwiritsidwa ntchito ngati zosungunulira ndikuwonetsa.
4.
5. Nthawi zambiri imagwiritsidwa ntchito ngati zosungunulira mu labotaries ndi kupanga.
