Codsiga Alaabta:
1.Ethanol waa dareere dabiici ah oo muhiim ah, oo si ballaaran loo isticmaalo daawada, rinjiga, alaabta nadaafadda, qurxinta, saliidda iyo dufanka iyo hababka kale, xisaabinta qiyaastii 50% isticmaalka guud ee ethanol. Ethanol waa walxo kiimiko ah oo aasaasi ah oo muhiim ah, oo loo isticmaalo soo saarista acetaldehyde, ethylene diene, ethylamine, ethyl acetate, acetic acid, chloroethane, iwm. , sunta cayayaanka, iwm, oo leh in ka badan 300 oo nooc oo badeecooyin ah, laakiin hadda isticmaalka ethanol sida dhexdhexaadinta alaabta kiimikada ayaa si tartiib tartiib ah u sii yaraanaysa, iyo alaabooyin badan, sida acetaldehyde, acetic acid, ethyl alcohol, hadda ma isticmaalin ethanol sida a alaabta ceeriin, laakiin alkolada ethyl sida alaabta ceeriin. Si kastaba ha noqotee, isticmaalka ethanol ee dhexdhexaadinta kiimikada ayaa si tartiib tartiib ah u sii yaraanaya, iyo alaabooyin badan sida acetaldehyde, acetic acid, ethyl khamriga hadda ma isticmaalayaan ethanol sida alaabta ceeriin, laakiin waxaa lagu beddelaa alaabooyin kale oo ceeriin ah. ethanol si gaar ah loo sifeeyay ayaa sidoo kale loo isticmaalaa samaynta cabitaannada. Si la mid ah methanol, ethanol waxa loo isticmaali karaa il tamar ahaan. Wadamada qaar waxay bilaabeen inay ethanol kaligood u isticmaalaan shidaal baabuur ama waxay ku milmeen shidaal (10% ama ka badan) si ay u badbaadiyaan shidaalka.
2.Waxa loo isticmaalaa sida dareere ah xabagta, rinjiga buufinta nitro, varnishes, cosmetics, khadyada, rinjiga, iwm, iyo sidoo kale alaabta ceeriin ah oo loogu talagalay soo saarista sunta cayayaanka, daawooyinka, caagadaha, balaastikada, fiilooyinka synthetic, saabuunta, iwm. , iyo sida barafowga, shidaalka, jeermiska jeermiska iyo wixii la mid ah. Warshadaha microelectronics, oo loo isticmaalo sida wasakhaynta iyo wasakhaynta, ayaa loo isticmaali karaa iyada oo lala kaashanayo wakiilka hoos u dhiga.
3. Loo isticmaalo sida reagent gorfaynta, sida dareeraha. Sidoo kale loo isticmaalo warshadaha dawooyinka.
4. Loo isticmaalo warshadaha elektiroonigga ah, loo isticmaalo sida wasakhaynta iyo wasakhaynta iyo maaddooyinka wakiilada xaalufinta.
5.Used milmi qaar ka mid ah daro organic electroplating aan milmi karin, sidoo kale loo isticmaalo sida hexavalent chromium yaraynta wakiilka in chemistry gorfaynta.
6.Used warshadaha khamriga, synthesis organic, jeermiska iyo sida dareere ah.
Qoraalada Kaydinta Alaabta:
1. Ku kaydi bakhaar qabow oo hawo leh.
2. Ka fogow dabka iyo isha kulaylka.
3. Heerkulka kaydinta waa in aanu dhaafin 37°C.
4.Ka ilaali weelka oo xiran.
5.Waa in si gooni ah loo kaydiyaa oksijiinta, acids, biraha alkali, amines, iwm, ha isku darin kaydinta.
6.Isticmaal nalalka aan qarxin iyo tas-hiilaadka hawo-siinta.
7. Mamnuuci isticmaalka qalabka farsamada iyo qalabka si fudud loo dhalin karo.
8.Aagga kaydinta waa in lagu qalabeeyaa qalab daawaynta degdega ah ee daadsan iyo agab hoy oo ku habboon.
