Dhibicda Karkari Ethylene Glycol iyo Falanqaynta Arrimaha Saamaynteeda leh
Ethylene glycol (Ethylene Glycol) waa walxo kiimiko ah oo si caadi ah loo isticmaalo, si weyn loogu isticmaalo barafeeyaha, resins, balaastikada, dareeraha iyo meelaha kale. Soo saarista kiimikada iyo codsiga, fahamka sifooyinka jidheed ee Ethylene Glycol, gaar ahaan barta karkarinta ee Ethylene Glycol, ayaa muhiim u ah wanaajinta cabirrada nidaamka iyo hubinta tayada badeecada.
Dulmarka guryaha aasaasiga ah iyo barta karkarinta ee glycol ethylene
Ethylene glycol waa dareere aan midab lahayn, ur lahayn, viscous leh qaacidada kiimikada C2H6O2. waxay leedahay heerkul aad u sarreeya oo ah 197.3 ° C (cadaadiska jawiga caadiga ah). Barta karkarinta sare ee glycol ethylene waxay ku siinaysaa xasilloonida codsiyada warshadaha badan, gaar ahaan hababka u baahan ka shaqeynta heerkulka sare, halkaas oo ay ku sii jiri karto xaaladda dareeraha ah, sidaas awgeed hagaajinta waxtarka habka.
Waxyaabaha saameeya barta karkarinta ee glycol ethylene
Barta karkarinta ee glycol ethylene ma saameynayso oo kaliya qaab dhismeedka molecular iyo xoogagga intermolecular, laakiin sidoo kale waxay si dhow ula xiriiraan arrimaha deegaanka ee dibadda. Waxyaabaha soo socda ayaa ah qaar ka mid ah arrimaha ugu waaweyn:
Saamaynta cadaadiska: Cadaadiska jawiga caadiga ah, barta karkarinta ee ethylene glycol waa 197.3°C. Haddii cadaadiska nidaamku isbeddelo, barta karkaraya sidoo kale way isbedeli doontaa. Caadi ahaan, barta karkarinta ayaa kor u kacda marka cadaadiska uu kordho, tanina waxay si gaar ah muhiim ugu tahay reactors-ka cadaadiska sarreeya ama cadaadiska sare ee cadaadiska sare.

Joogitaanka wasakhda: Meesha karkaraya ee ethylene glycol way isbedeli kartaa haddii ay ku jirto wasakh. Wasakhda qaar ayaa laga yaabaa inay hoos u dhigto barta karkarinta ee glycol ethylene, halka kuwa kalena ay keeni karaan korodhka barta karkarinta. Tani waxay ka dhigaysaa baahida sare ee xakamaynta nadiifinta glycol ee wax soo saarka warshadaha.

Saamaynta Qalabka Xalka: Marka glycol loo isticmaalo sida dareere ama isku-darka, barta karkaraya waxaa saameeya solute. Tusaale ahaan, marka glycol lagu qaso biyo, barta karkaraya ee isku dhafka ayaa laga yaabaa inay ka hooseyso tan glycol saafi ah ama biyo saafi ah. Fahamka hantidani waxay muhiim u tahay naqshadaynta iyo hawlgalka habab ka kooban qaybo badan oo ku lug leh glycols.

Codsiyada barta karkarinta Glycol ee warshadaha
Wax soo saarka warshadaha, barta karkaraya ee glycol ethylene ayaa ah tixraac muhiim ah oo loogu talagalay naqshadeynta reactors, tiirarka distillation iyo qalabka kale. Gaar ahaan falcelinta heerkulka sare, aqoonta saxda ah ee barta karkaraya ee ethylene glycol waxay ka caawisaa in laga fogaado kulaylka badan iyo in la hubiyo xasilloonida falcelinta. Inta lagu jiro habka distillation iyo kala-soocidda, ogaanshaha barta karkarinta ayaa kaa caawin karta in si sax ah loo xakameeyo xaaladaha kala-soocidda iyo hagaajinta nadiifinta alaabta.
Gabagabo
Barta karkarinta ee ethylene glycol waa halbeeg jireed oo muhiim ah oo ay saameeyaan arrimo kala duwan. Fahamka iyo maaraynta sifooyinka barta karkarinta ee ethylene glycol waxay gacan ka geysan kartaa wanaajinta habka wax soo saarka warshadaha iyo hagaajinta tayada alaabta. Ficil ahaan, injineeradu waa inay tixgeliyaan arrimo ay ka mid yihiin cadaadiska, wasakhda iyo guryaha xalalka si ay si buuxda uga faa'iideystaan sifooyinka jireed ee glycol ethylene oo ay u hubiyaan hanaan wax soo saar deggan oo hufan.
