mankhwala makhalidwe

Chilinganizo cha mankhwala: (CH2OH)2 Kulemera kwa maselo: 62.068 CAS: 107-21-1 EINECS: 203-473-3 [5 Malo osungunuka: -12.9 ℃ Malo otentha: 197.3 ℃

Chiyambi cha malonda ndi mawonekedwe ake

CH2OH 2, yomwe ndi diol yosavuta kwambiri.Ethylene glycol ndi madzi opanda mtundu, opanda fungo, okoma omwe ali ndi kawopsedwe kakang'ono kwa nyama.Ethylene glycol imatha kusungunuka ndi madzi ndi acetone, koma kusungunuka kwake mu ethers kumakhala kochepa.Amagwiritsidwa ntchito ngati zosungunulira, antifreeze ndi kupanga polyester yaiwisi.Polima wa ethylene glycol, polyethylene glycol (PEG), ndi chothandizira kusamutsa gawo ndipo amagwiritsidwanso ntchito pophatikiza ma cell.

ntchito

Amagwiritsidwa ntchito popanga poliyesitala, poliyesitala, poliyesitala utomoni, kuyamwa chinyezi, plasticizer, pamwamba yogwira wothandizila, kupanga CHIKWANGWANI, zodzoladzola ndi zophulika, ndi ntchito monga zosungunulira utoto, inki, etc., kukonzekera injini antifreeze wothandizila, mpweya dehydrating wothandizira, kupanga utomoni, itha kugwiritsidwanso ntchito ngati cellophane, CHIKWANGWANI, zikopa, zomatira kunyowetsa wothandizira.Itha kupanga PET yopangira utomoni, CHIKWANGWANI PET chomwe ndi poliyesitala CHIKWANGWANI, kagawo ka botolo PET popanga mabotolo am'madzi amchere ndi zina zotero.Itha kutulutsanso utomoni wa alkyd, glyoxal, ndi zina zambiri, zomwe zimagwiritsidwanso ntchito ngati antifreeze.Kuphatikiza pa kugwiritsidwa ntchito ngati antifreeze pamagalimoto, imagwiritsidwanso ntchito kunyamula mphamvu zoziziritsa za mafakitale, zomwe zimatchedwa carrier refrigerant, ndipo zitha kugwiritsidwanso ntchito ngati condensing agent ngati madzi.
Ethylene glycol methyl etha mndandanda mankhwala ndi apamwamba organic solvents, monga inki yosindikiza, mafakitale kuyeretsa wothandizila, ❖ kuyanika (nitro CHIKWANGWANI utoto, vanishi, enamel), mkuwa TACHIMATA mbale, kusindikiza ndi utoto solvents ndi diluents;Itha kugwiritsidwa ntchito ngati zopangira zopangira mankhwala monga intermediates mankhwala, intermediates mankhwala ndi kupanga ananyema madzimadzi.Monga electrolytes kwa electrolytic capacitors, mankhwala CHIKWANGWANI utoto wothandizila pofufuta, etc. Ntchito monga nsalu zothandizira, kupanga madzi utoto, komanso fetereza ndi mafuta kuyenga popanga desulfurizer zopangira.
Ethylene glycol iyenera kudziwidwa ikagwiritsidwa ntchito ngati chonyamulira firiji:
1. Kuzizira kumasintha ndi kuchuluka kwa ethylene glycol mu njira yamadzimadzi.Pamene ndende ili pansi pa 60%, kuzizira kumachepa ndi kuwonjezeka kwa ndende ya ethylene glycol mu njira yamadzimadzi, koma pamene ndende idutsa 60%, kuzizira kumawonjezeka ndi kuwonjezeka kwa ndende ya ethylene glycol, ndi kukhuthala. kumawonjezeka ndi kuwonjezeka kwa ndende.Pamene ndende ifika 99.9%, kuzizira kwake kumakwera kufika -13.2 ℃, chomwe ndi chifukwa chofunika kwambiri chomwe antifreeze (antifreeze mayi wamadzimadzi) sichingagwiritsidwe ntchito mwachindunji, ndipo chiyenera kukopa chidwi cha wogwiritsa ntchito.
2. Ethylene glycol lili hydroxyl gulu, amene oxidized kuti glycolic asidi ndiyeno asidi oxalic, ndiye glycolic asidi (oxalic acid), munali 2 carboxyl magulu, pamene ntchito pa 80-90 ℃ kwa nthawi yaitali.Oxalic acid ndi zotuluka zake zimakhudza choyamba chapakati mitsempha, kenako mtima, kenako impso.Ethylene glycol glycolic acid, kuchititsa dzimbiri ndi kutayikira kwa zida.Choncho, pokonzekera antifreeze, payenera kukhala chotetezera kuteteza dzimbiri, aluminiyamu ndi mapangidwe a sikelo.

phukusi ndi transport

B. Izi angagwiritsidwe ntchito,, 25KG, 200KG, 1000KGBAERRLS.
C. Sungani chosindikizidwa mu malo ozizira, owuma ndi mpweya wokwanira m'nyumba.Zotengera ziyenera kutsekedwa mwamphamvu mukatha kugwiritsa ntchito chilichonse musanagwiritse ntchito.
D. Mankhwalawa ayenera kusindikizidwa bwino panthawi yoyendetsa kuti ateteze chinyezi, alkali wamphamvu ndi asidi, mvula ndi zonyansa zina kuti zisasakanike.
