Ifomula yamakhemikhali: (CH2OH)2 Isisindo sama-molecule: 62.068 CAS: 107-21-1 EINECS: 203-473-3 [5 Iphuzu lokuncibilika: -12.9 ℃ Iphuzu lokubila: 197.3 ℃

Isingeniso somkhiqizo kanye nezici

I-CH2OH 2, okuyi-diol elula kakhulu. I-Ethylene glycol iwuketshezi olungenambala, olungenaphunga, olumnandi olunobuthi obuphansi ezilwaneni. I-Ethylene glycol ingancibilika ndawonye ngamanzi kanye ne-acetone, kodwa ukuncibilika kwayo kuma-ether kuncane. Isetshenziswa njenge-solvent, i-antifreeze kanye nezinto zokwenziwa ze-polyester. I-polymer ye-ethylene glycol, i-polyethylene glycol (PEG), iyisikhuthazi sokudlulisa isigaba futhi isetshenziswa nasekuhlanganiseni amaseli.

sebenzisa

Isetshenziswa kakhulu ekwenzeni i-polyester, i-polyester, i-polyester resin, into emunca umswakama, i-plasticizer, i-surface active agent, i-synthetic fiber, izimonyo kanye nezinto eziqhumayo, futhi isetshenziswa njengesithambisi samadayi, i-ink, njll., ukulungiswa kwe-ejenti yokulwa nokuqandisa injini, i-ejenti yokuqeda amanzi ngegesi, i-resin yokukhiqiza, ingasetshenziswa futhi kwi-cellophane, i-fiber, isikhumba, i-adhesive wetting agent. Ingakhiqiza i-synthetic resin PET, i-fiber PET okuyi-polyester fiber, i-bottle slice PET yokwenza amabhodlela amanzi amaminerali nokunye. Ingakhiqiza futhi i-alkyd resin, i-glyoxal, njll., esetshenziswa futhi njenge-antifreeze. Ngaphezu kokusetshenziswa njenge-antifreeze yezimoto, isetshenziselwa futhi ukuthutha amandla okupholisa ezimbonini, ngokuvamile abizwa ngokuthi i-carrier refrigerant, futhi ingasetshenziswa njenge-condensing agent njengamanzi.
Imikhiqizo yochungechunge lwe-ethylene glycol methyl ether iyizinyibilikisi zekhwalithi ephezulu, njenge-inki yokunyathelisa, i-ejenti yokuhlanza yezimboni, i-coating (upende we-nitro fiber, i-varnish, i-enamel), ipuleti elimbozwe ngethusi, izinyibilikisi zokunyathelisa nokudaya kanye ne-diluents; Ingasetshenziswa njengezinto zokusetshenziswa zemikhiqizo yamakhemikhali njengezinto zokuxuba izibulala-zinambuzane, izinto zokuxuba zemithi kanye noketshezi lwamabhuleki okwenziwa. Njengezinto zokuxuba ze-electrolytic capacitors, i-ejenti yokudaya i-fiber yamakhemikhali yokushiswa kwesikhumba, njll. Isetshenziswa njengezinsiza zendwangu, udayi woketshezi wokwenziwa, kanye nomanyolo kanye nokuhluzwa kwamafutha ekukhiqizweni kwezinto zokusetshenziswa ze-desulfurizer.
I-ethylene glycol kufanele iqashelwe uma isetshenziswa njengesiqandisi sokuthwala:
1. Iphuzu lokuqandisa liyashintsha ngokuhlushwa kwe-ethylene glycol esixazululweni samanzi. Uma ukuhlushwa kungaphansi kwama-60%, iphuzu lokuqandisa liyancipha ngokuhlushwa kwe-ethylene glycol esixazululweni samanzi, kodwa uma ukuhlushwa kudlula ama-60%, iphuzu lokuqandisa liyanda ngokuhlushwa kwe-ethylene glycol, futhi i-viscosity iyanda ngokuhlushwa. Lapho ukuhlushwa kufinyelela kuma-99.9%, iphuzu layo lokuqandisa likhuphuka lifike ku--13.2℃, okuyisizathu esibalulekile sokuthi kungani i-antifreeze egxilile (i-antifreeze mother liquid) ingasetshenziswa ngqo, futhi kumele idonse ukunaka komsebenzisi.
2. I-Ethylene glycol iqukethe iqembu le-hydroxyl, elizoguqulwa libe yi-glycolic acid bese kuba yi-oxalic acid, okungukuthi, i-glycolic acid (i-oxalic acid), equkethe amaqembu amabili e-carboxyl, uma isebenza ku-80-90 ℃ isikhathi eside. I-Oxalic acid kanye nemikhiqizo yayo engaphansi kwayo kuqala kuthinta uhlelo lwezinzwa oluphakathi, bese kuba yinhliziyo, bese kuba yizinso. I-Ethylene glycol glycolic acid, ebangela ukugqwala nokuvuza kwemishini. Ngakho-ke, ekulungiseleleni i-antifreeze, kumele kube nesivikelo sokuvimbela ukugqwala kwensimbi, i-aluminium kanye nokwakheka kwesikali.

iphakheji kanye nokuthuthwa

B. Lo mkhiqizo ungasetshenziswa,,25KG，200KG,1000KGBAERRLS。
C. Gcina kuvaliwe endaweni epholile, eyomile futhi enomoya opholile ngaphakathi. Izitsha kufanele zivalwe kahle ngemva kokusetshenziswa ngakunye ngaphambi kokusetshenziswa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuthuthwa ukuze kuvinjelwe umswakama, i-alkali enamandla ne-asidi, imvula nokunye ukungcola ekuxubeni.
