Soo bandhigida alaabta iyo sifooyinka

CH2OH 2, kaas oo ah diol ugu fudud.Ethylene glycol waa dareere aan midab lahayn, ur lahayn, macaan oo sunta xayawaanka ku yar.Ethylene glycol waxay noqon kartaa mid si wadajir ah ugu milmi kara biyo iyo acetone, laakiin ku milmideeda ethers waa yar tahay.Loo isticmaalo sida dareere, ka-hortagga-freeze iyo alaabta ceeriin ee polyester-ka synthetic.polymerka ethylene glycol, polyetylen glycol (PEG), waa kicinta wareejinta wejiga waxaana sidoo kale loo isticmaalaa isku-dhafka unugyada.

isticmaal

Inta badan loo isticmaalo samaynta polyester, polyester, xabagta polyester, nuuga qoyaan, plasticizer, wakiilka firfircoon dusha, fiber synthetic, isku qurxiyo iyo walxaha qarxa, oo loo isticmaalo sida dareere ah dheeh, khad, iwm, diyaarinta wakiilka antifreeze engine, wakiilka fuuqbaxa gaaska, xabagta wax soo saarka, sidoo kale waxaa loo isticmaali karaa cellophane, fiber, maqaar, wakiilka qoynta xabagta.Waxay soo saari kartaa PET resin synthetic, fiber PET oo ah fiber polyester, jeex dhalada PET ee samaynta dhalooyinka biyaha macdanta iyo wixii la mid ah.Waxa kale oo uu soo saari karaa resin alkyd, glioxal, iwm., oo sidoo kale loo isticmaalo sidii barafka.Marka laga soo tago in loo isticmaalo sida barafowga baabuurta, waxaa sidoo kale loo isticmaalaa gaadiidka awoodda qaboojinta warshadaha, guud ahaan loo yaqaan qaboojiyaha side, waxaana sidoo kale loo isticmaali karaa sida walaxda qaboojinta sida biyaha.
Alaabooyinka taxanaha Ethylene glycol methyl ether waa dareerayaal dabiici ah oo tayo sare leh, sida khad daabacan, wakiilka nadiifinta warshadaha, daahan (Rinjiga fiber nitro, varnish, dhaldhalaalka), saxan dahaarka ah oo naxaas ah, dareerayaasha daabacaadda iyo dheehaynta iyo dareeraha;Waxa loo isticmaali karaa alaab cayriin ah alaabta kiimikaad sida dhex-dhexaadiyeyaasha sunta cayayaanka, dhexdhexaadiyeyaasha dawooyinka iyo dareeraha biriiga synthetic.Sida electrolytes loogu talagalay capacitors electrolytic, wakiilka dheeha fiber kiimikaad for harag, iwm Loo isticmaalo sida kaaliyeyaasha dunta, midabada dareere synthetic, iyo sidoo kale bacriminta iyo sifaynta saliidda ee wax soo saarka ee desulfurizer alaabta ceeriin.
Ethylene glycol waa in la xuso marka loo isticmaalo qaboojiyaha side:
1. Barafka qaboojintu waxay is beddeshaa isku-ururinta glycol ethylene ee xal aqueous ah.Marka fiirsashada ay ka hooseyso 60%, barta barafku waxay hoos u dhacdaa kororka fiirsashada ethylene glycol ee xalka aqueous, laakiin marka fiirsashada ay dhaafto 60%, barta barafku waxay kordhisaa kororka fiirsashada glycol ethylene, iyo viscosity waxay kordhisaa korodhka feejignaanta.Marka fiirsashada ay gaarto 99.9%, barta qaboojintu waxay kor u kacdaa -13.2 ℃, taas oo ah sababta muhiimka ah ee ka hortagga barafka (dareeraha hooyada ka hortagga) aan si toos ah loo isticmaali karin, waana inay soo jiidataa dareenka isticmaalaha.
2. Ethylene glycol waxa ku jira hydroxyl group, kaas oo lagu shubi doono glycolic acid ka dibna oxalic acid, yacni, glycolic acid (oxalic acid), oo ka kooban 2 kooxood oo carboxyl ah, marka ay shaqaynayso 80-90 ℃ muddo dheer.Oxalic acid iyo waxyaabaha ka soo baxa waxay saameeyaan marka hore habka dhexe ee neerfayaasha, ka dibna wadnaha, ka dibna kelyaha.Ethylene glycol glycolic acid, taasoo keenta daxalka iyo daadinta qalabka.Sidaa darteed, diyaarinta antifreeze, waa in ay jiraan wax ilaaliya si looga hortago daxalka birta, aluminium iyo samaynta miisaanka.

xirmo iyo gaadiid

B. Alaabtan waxa loo isticmaali karaa,,25KG,200KG,1000KGBAERRLS.
C. Ku kaydi meel qabow, qalalan oo hawo leh oo gudaha ah.Weelasha waa in si adag loo xidhaa ka dib isticmaal kasta ka hor intaan la isticmaalin.
D. Alaabtan waa in si fiican loo xiraa inta lagu jiro gaadiidka si looga hortago qoyaanka, alkali xooggan iyo aashitada, roobka iyo wasakhda kale ee isku darka.
