Intshayelelo yemveliso kunye neempawu

I-CH2OH 2, eyona diol ilula.I-Ethylene glycol ngulwelo olungenambala, olungenavumba, oluswiti olunetyhefu ephantsi kwizilwanyana.I-Ethylene glycol inokunyibilika ngokudibeneyo ngamanzi kunye ne-acetone, kodwa ukunyibilika kwayo kwi-ethers kuncinci.Isetyenziswa njenge-solvent, i-antifreeze kunye ne-synthetic polyester ekrwada.Ipolymer ye-ethylene glycol, i-polyethylene glycol (PEG), i-catalyst yokudluliselwa kwesigaba kwaye isetyenziselwa ukudibanisa iseli.

sebenzisa

Isetyenziselwa ukwenza i-polyester, i-polyester, i-polyester resin, i-absorbent yokufuma, i-plasticizer, i-agent esebenzayo, i-synthetic fiber, izinto zokuthambisa kunye neziqhushumbisi, kwaye isetyenziswe njengesinyibilikisi sedayi, ii-inki, njl. I-resin yokuvelisa, ingasetyenziselwa i-cellophane, i-fiber, isikhumba, i-adhesive wetting agent.Inokuvelisa i-resin synthetic PET, i-fiber PET eyi-polyester fiber, isilayi sebhotile i-PET yokwenza iibhotile zamanzi ezimbiwa njalo njalo.Inokuvelisa i-alkyd resin, i-glyoxal, njl., ekwasetyenziswa njenge-antifreeze.Ukongeza ekusetyenzisweni njenge-antifreeze kwiimoto, ikwasetyenziselwa ukuthutha umthamo wokupholisa kwimizi-mveliso, ebizwa ngokuba yi-carrier refrigerant, kwaye inokusetyenziswa njenge-ejenti yokupholisa njengamanzi.
Iimveliso ze-Ethylene glycol methyl ether zikumgangatho ophezulu wezinto ezinyibilikayo zendalo, njenge-inki yokuprinta, i-arhente yokucoca i-industrial, i-coating (ipeyinti yefiber ye-nitro, ivanishi, i-enamel), ipleyiti egqunywe ngobhedu, ukuprinta kunye nokudaya izinyibilikisi kunye ne-diluents;Ingasetyenziswa njengemathiriyeli ekrwada kwiimveliso zekhemikhali ezifana neziphakathi zesibulali-zinambuzane, i-pharmaceutical intermediates kunye ne-synthetic brake fluid.Njengoko i-electrolytes ye-electrolytic capacitors, i-agent ye-chemical fiber dyeing for tanning, njl. Isetyenziswa njengezinto ezincedisa i-textile, iidayi zolwelo zokwenziwa, kunye nesichumiso kunye nokucocwa kwe-oyile kwimveliso ye-desulfurizer ekrwada.
I-Ethylene glycol kufuneka iqatshelwe xa isetyenziswe njengefriji ephetheyo:
1. Iqondo lokukhenkceza litshintsha ngokuxinwa kwe-ethylene glycol kwisisombululo samanzi.Xa ugxininiso lungaphantsi kwe-60%, indawo yokukhenkceza iyancipha ngokunyuka koxinzelelo lwe-ethylene glycol kwisisombululo se-aqueous, kodwa xa i-concentration idlula i-60%, indawo yokukhenkceka iyanda ngokunyuka kwe-ethylene glycol, kunye ne-viscosity. kwandisa ngokunyuka koxinzelelo.Xa ugxininiso lufikelela kwi-99.9%, indawo yokukhenkceza iphakama ukuya kwi -13.2 ℃, isizathu esibalulekileyo sokuba i-antifreeze egxininisiweyo (i-antifreeze mother liquid) ayinakusetyenziswa ngokuthe ngqo, kwaye kufuneka itsalele ingqalelo yomsebenzisi.
2. I-Ethylene glycol iqulethe iqela le-hydroxyl, eliya kuxutywa kwi-glycolic acid kwaye emva koko kwi-oxalic acid, oko kukuthi, i-glycolic acid (i-oxalic acid), equkethe amaqela angama-2 e-carboxyl, xa isebenza kwi-80-90 ℃ ixesha elide.I-Oxalic acid kunye neemveliso zayo zichaphazela kuqala inkqubo ye-nervous central, emva koko intliziyo, kunye nezintso.I-Ethylene glycol glycolic acid, ebangela ukubola kunye nokuvuza kwezixhobo.Ngoko ke, ekulungiseleleni i-antifreeze, kufuneka kubekho i-preservative ukukhusela i-corrosion yensimbi, i-aluminium kunye nokubunjwa kwesikali.
