Midab la'aan cad 99.5% dareeraha Ethyl Acetate ee darajada warshadaha
Isticmaalka
Ethyl acetate waa dareere warshadeed oo aad u fiican waxaana loo isticmaali karaa fiber nitrate, fiber ethyl, caag chlorinated iyo vinyl resin, cellulose acetate, cellulose butyl acetate iyo caag synthetic, iyo sidoo kale khadadka nitro dareeraha dareeraha ah ee sawirqaadayaasha.Waxa loo isticmaali karaa sidii dareere xabag ah, rinji khafiif ah.Loo isticmaalo sidii reagent gorfaynta, walaxda caadiga ah iyo dareeraha falanqaynta chromatographic.Warshadaha dharka waxaa loo isticmaali karaa sida wakiilka nadiifinta, warshadaha cuntada waxaa loo isticmaali karaa sida wakiilka soo saarista dhadhanka khamriga oo wax laga beddelay, laakiin sidoo kale loo isticmaalo habka dawooyinka iyo wakiilka soo saarista aashitada organic.Ethyl acetate sidoo kale waxaa loo isticmaalaa in lagu sameeyo midabyo, daawooyin iyo uunsi.
Kaydinta waxay ku taal heerkulka qolka waana in lagu hayaa hawo iyo engegan, iska ilaali soo-gaadhista qorraxda iyo huurka.Ethyl acetate waxaa ku wasakhaysan kara gubasho, oksaydhiyeyaasha, acids xooggan iyo saldhigyada, sidaas darteed waxay u baahan tahay in laga saaro walxahan marka la kaydiyo oo loo isticmaalo si looga fogaado khataraha.
Xaaladaha Codsiga
Ethyl acetate waxay leedahay codsiyo badan oo kala duwan.Qaar ka mid ah meelaha waaweyn ee wax soo saarka iyo isticmaalka waxaa ka mid ah:
1. Wax-soo-saarka meelaha sida isqurxinta, daryeelka qofka iyo cadarka.
2. Soo saarista midabada, resins, dahaarka iyo khadadka, sida dareerayaasha.
3. Warshadaha dawooyinka, waxa loo isticmaali karaa sida dareere iyo soosaar.
4. Si weyn loogu isticmaalo warshadaha cuntada iyo cabitaanka, biirka, khamriga, cabitaannada, xawaashyada, casiirka khudradda iyo beeraha kale sida walxaha dhadhanka.
5. Waxaa inta badan loo isticmaalaa sida dareere ah shaybaarada iyo wax soo saarka.
