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 ngokufanayo ngamanzi ne-acetone, kodwa ukunyibilika kwayo kuma-ether kuncane.Isetshenziswa njenge-solvent, i-antifreeze kanye ne-synthetic polyester impahla eluhlaza.I-polymer ye-ethylene glycol, i-polyethylene glycol (PEG), iyisisusa sokudlulisa isigaba futhi isetshenziselwa ukuhlanganisa amaseli.

sebenzisa

Ikakhulukazi isetshenziselwa ukwenza i-polyester, i-polyester, i-polyester resin, imunca umswakama, i-plasticizer, i-ejenti esebenzayo, i-synthetic fiber, izimonyo neziqhumane, futhi isetshenziswa njenge-solvent yodayi, oyinki, njll. ukukhiqiza i-resin, ingasetshenziselwa i-cellophane, i-fiber, isikhumba, i-adhesive wetting agent.Ingakhiqiza i-PET resin yokwenziwa, i-fiber PET eyi-polyester fiber, i-PET slice yebhodlela yokwenza amabhodlela amanzi amaminerali nokunye.Ingaphinda ikhiqize i-alkyd resin, i-glyoxal, njll., iphinde isetshenziswe njenge-antifreeze.Ngaphezu kokusetshenziswa njenge-antifreeze ezimotweni, iphinde isetshenziselwe ukuthutha umthamo wokupholisa wezimboni, ngokuvamile obizwa nge-carrier refrigerant, futhi ingasetshenziswa njenge-ejenti yokujiya njengamanzi.
Imikhiqizo yochungechunge lwe-Ethylene glycol methyl ether iyizincibilikisi zemvelo ezisezingeni eliphakeme, njengeyinki yokunyathelisa, i-ejenti yokuhlanza izimboni, ukugqoka (upende we-nitro fiber, i-varnish, i-koqweqwe lwawo), ipuleti eliboshwe ngethusi, izincibilikisi zokunyathelisa nokudaya kanye nezihlanzi;Ingasetshenziswa njengezinto zokusetshenziswa emikhiqizweni yamakhemikhali njengezibulala-zinambuzane, ama-intermediate emithi kanye ne-synthetic brake fluid.Njengama-electrolyte ama-electrolytic capacitor, i-chemical fiber dyeing agent yokushuka, njll. Isetshenziswa njengezinsizi zendwangu, odayi boketshezi bokwenziwa, kanye nokucwengwa kukamanyolo nokucwengwa kukawoyela ekukhiqizeni izinto ezingavuthiwe ze-desulfurizer.
I-Ethylene glycol kufanele iqashelwe uma isetshenziswa njengesiqandisi esithwalayo:
1. Iphuzu lokuqandisa liyashintsha ngokugxila kwe-ethylene glycol kusisombululo esinamanzi.Lapho ukuhlushwa kungaphansi kwama-60%, indawo yokuqandisa iyancipha ngokukhula kokuhlushwa kwe-ethylene glycol esixazululweni esinamanzi, kepha lapho ukugxila kudlula ama-60%, indawo yokuqandisa iyanda ngokwanda kokuhlushwa kwe-ethylene glycol, kanye ne-viscosity. iyanda ngokukhula kokugxila.Lapho ukugxilisa ingqondo kufinyelela ku-99.9%, iphoyinti layo lokuqandisa likhuphukela ku--13.2℃, okuyisizathu esibalulekile esenza ukuthi i-antifreeze egxilile (i-antifreeze mother liquid) ingakwazi ukusetshenziswa ngokuqondile, futhi kufanele idonse ukunaka komsebenzisi.
2. I-Ethylene glycol iqukethe iqembu le-hydroxyl, elizokwenziwa i-oxidized ku-glycolic acid bese kuba i-oxalic acid, okungukuthi, i-glycolic acid (i-oxalic acid), equkethe amaqembu angu-2 e-carboxyl, lapho isebenza ku-80-90 ℃ isikhathi eside.I-Oxalic acid kanye nemikhiqizo yayo ithinta kuqala isimiso sezinzwa esimaphakathi, bese kuba inhliziyo, bese kuba izinso.I-Ethylene glycol glycolic acid, ebangela ukugqwala nokuvuza kwemishini.Ngakho-ke, ekulungiseleleni i-antifreeze, kufanele kube ne-preservative ukuvimbela ukugqwala kwensimbi, i-aluminium kanye nokwakheka kwesikali.

iphakethe kanye nezokuthutha

B. Lo mkhiqizo ungasetshenziswa,,25KG,200KG,1000KGBAERRLS.
C. Gcina kuvaliwe endlini epholile, eyomile futhi engenamoya.Iziqukathi kufanele zivalwe ngokuqinile ngemva kokusetshenziswa ngakunye ngaphambi kokusetshenziswa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuthutha ukuvimbela umswakama, i-alkali enamandla ne-asidi, imvula nokunye ukungcola ekuxubeni.
