Intshayelelo yemveliso kunye neempawu zayo

I-CH2OH 2, eyona diol ilula. I-Ethylene glycol lulwelo olungenambala, olungenavumba, olumnandi olunetyhefu encinci kwizilwanyana. I-Ethylene glycol inokunyibilika kunye namanzi kunye ne-acetone, kodwa ukunyibilika kwayo kwi-ethers kuncinci. Isetyenziswa njenge-solvent, i-antifreeze kunye ne-polyester yokwenziwa. I-polymer ye-ethylene glycol, i-polyethylene glycol (PEG), sisincedisi sokudlulisa i-phase kwaye ikwasetyenziswa ekuhlanganiseni iiseli.

sebenzisa

Isetyenziswa kakhulu ekwenzeni i-polyester, i-polyester, i-polyester resin, i-moisture absorbent, i-plasticizer, i-surface active agent, i-synthetic fiber, izinto zokuthambisa kunye neziqhushumbisi, kwaye isetyenziswa njengesinyibilikisi sedayi, i-inki, njl.njl., ukulungiswa kwe-engine antifreeze agent, i-gas dehydrating agent, i-manufacturing resin, ingasetyenziselwa ne-cellophane, i-fiber, isikhumba, i-adhesive wetting agent. Ingavelisa i-synthetic resin PET, i-fiber PET eyi-polyester fiber, i-bottle slice PET yokwenza iibhotile zamanzi amaminerali njl.njl. Ingavelisa ne-alkyd resin, i-glyoxal, njl.njl., ekwasetyenziswa njenge-antifreeze. Ukongeza ekusetyenzisweni njenge-antifreeze kwiimoto, ikwasetyenziselwa ukuthutha amandla okupholisa kwimizi-mveliso, abizwa ngokuba yi-carrier refrigerant, kwaye ingasetyenziselwa njenge-condensing agent efana namanzi.
Iimveliso zochungechunge lwe-ethylene glycol methyl ether zizinto ezinyibilikisa izinto eziphilayo ezikumgangatho ophezulu, njenge-inki yokuprinta, i-arhente yokucoca imboni, i-coating (ipeyinti ye-nitro fiber, i-varnish, i-enamel), ipleyiti egqunywe ngekopolo, izinyibilikisi zokuprinta nokudaya kunye ne-diluents; Ingasetyenziswa njengezinto eziluhlaza kwiimveliso zeekhemikhali ezifana nezinyibilikisi zezinambuzane, izinto ezinyibilikisa amayeza kunye ne-brake fluid yokwenziwa. Njengee-electrolytes zee-capacitors ze-electrolytic, i-arhente yokudaya i-fiber yekhemikhali yokutshisa, njl.njl. Isetyenziswa njengee-auxiliaries zelaphu, iidayi zolwelo zokwenziwa, kunye nesichumiso kunye nokucocwa kweoyile kwimveliso yezinto eziluhlaza ze-desulfurizer.
I-ethylene glycol kufuneka iqatshelwe xa isetyenziswa njenge-carrier refrigerant:
1. Inqanaba lokuqandisa liyatshintsha xa i-ethylene glycol ikwisisombululo samanzi. Xa uxinzelelo lungaphantsi kwama-60%, inqanaba lokuqandisa liyancipha xa i-ethylene glycol inyuka xa ikwisisombululo samanzi, kodwa xa uxinzelelo ludlula ama-60%, inqanaba lokuqandisa liyanda xa i-ethylene glycol inyuka, kwaye i-viscosity iyanda xa ikwinqanaba lokuqandisa. Xa uxinzelelo lufikelela kuma-99.9%, inqanaba layo lokuqandisa linyuka liye kuma--13.2℃, nto leyo esona sizathu sibalulekileyo sokuba i-antifreeze egxininisiweyo (i-antifreeze mother liquid) ingasetyenziswa ngokuthe ngqo, kwaye kufuneka itsale ingqalelo yomsebenzisi.
2. I-ethylene glycol ineqela le-hydroxyl, eliza kunyibilikiswa libe yi-glycolic acid lize emva koko libe yi-oxalic acid, oko kukuthi, i-glycolic acid (i-oxalic acid), equlathe amaqela amabini e-carboxyl, xa isebenza kwi-80-90 ℃ ixesha elide. I-oxalic acid kunye neemveliso zayo zichaphazela kuqala inkqubo ye-nervous central, emva koko intliziyo, ize emva koko ibe zizintso. I-ethylene glycol glycolic acid, ebangela ukubola nokuvuza kwezixhobo. Ke ngoko, xa kulungiselelwa i-antifreeze, kufuneka kubekho isigcini sokuthintela ukubola kwentsimbi, i-aluminium kunye nokwenziwa kwesikali.
