Barta karkarinta ee Ethylene Glycol iyo falanqaynta hantida kiimikada
Warshadaha kiimikada, ethylene glycol (Ethylene Glycol) waa walxo kiimiko ah oo ceeriin ah oo muhiim ah oo si weyn loogu isticmaalo meelo kala duwan sida soosaarka antifreeze iyo resin. Fahamka sifooyinka physicochemical ee Ethylene Glycol, gaar ahaan barta karkaraya, ayaa muhiim u ah codsigeeda warshadaha. Maqaalkan, barta karkaraya ee glycol ethylene iyo arrimaha la xidhiidha saamaynta ayaa si faahfaahsan looga hadli doonaa.
Astaamaha Aasaasiga ah ee Ethylene Glycol iyo Barteeda Karkari
Ethylene glycol waa dareere viscous ah oo aan midab lahayn, ur lahayn, ur macaan leh oo leh qaacidada kiimikada C₂H₆O₂. Diol ahaan, ethylene glycol waxay leedahay hygroscopicity xoog leh iyo sifooyin milmayn wanaagsan. Meesha karkaraya ee ethylene glycol waa 197.3 ° C. Qiimahan, oo lagu cabbiro cadaadiska atmospheric, ayaa ka tarjumaysa xasilloonida qaab-dhismeedkeeda kelli iyo xoogga curaarta hydrogen-ka intermolecular.
Qodobbada saameeya barta karkarinta iyo muhiimada warshadaha
Barta karkaraya ee glycol ethylene waxaa saameeya dhowr arrimood. Isku-xidhka hydrogen-ka ee qaab-dhismeedka molecular waxay saameyn weyn ku leedahay barta karkarinta. Unugyada ethylene glycol molecule waxa ay ka kooban yihiin laba kooxood oo hydroxyl (-OH), kuwaas oo ay ku xidhan yihiin curaarta hydrogen, taas oo ka dhigaysa xoogaga intermolecular ee ethylene glycol mid xoog leh oo u horseedaya meel karkarinaysa. Miisaanka molecular ee glycol ethylene wuxuu kaloo saameeyaa barta karkarinta, iyadoo miisaannada unugyadu ay u baahan yihiin tamar badan si uumi u baxo.
Codsiyada warshadaha, barta karkaraya ee glycol ethylene waxay saameyn weyn ku leedahay waxqabadkeeda sida dareeraha, qaboojiyaha iyo alaabada kale. Tusaale ahaan, barta karkarinta sare waxay ka dhigaysaa glycol mid deggan oo aan isbeddelayn heerkulka sare, sidaas darteed hubinta waxtarkeeda qaboojiyeyaasha iyo barafka ka-hortagga.
Taxadir in codsiga dhabta ah
Markaad isticmaasho ethylene glycol, fiiro gaar ah ayaa loo baahan yahay in la bixiyo isdhexgalka barta karkarinta ee walxaha kale. Tusaale ahaan, isku-dhafka ama xalalka isku dhafan, walxaha kale waxay saameyn karaan barta karkarinta ee glycol ethylene iyo sidaas sifooyinka ugu dambeeya ee alaabta. Aqoonta barta karkaraya ee ethylene glycol waxay sidoo kale gacan ka geysan kartaa hagaajinta hababka wax soo saarka warshadaha, sida xakamaynta heerkulka inta lagu jiro qulqulka iyo xoojinta.
Marka la soo koobo, fahamka barta karkarinta ee ethylene glycol ayaa muhiim u ah codsigeeda warshadaha. Iyadoo la fahmayo hantida jireed ee ethylene glycol, waxqabadkeeda wax soo saarka iyo codsiga si fiican ayaa loo xakameyn karaa si kor loogu qaado tayada iyo xasiloonida alaabta.
