Ethylene Glycol |107-21-1
Mafotokozedwe Akatundu:
Ethylene glycol ndiye diol yosavuta kwambiri.Ethylene glycol ndi yopanda mtundu, yopanda fungo,fungokumwa madzi okhala ndi kawopsedwe kochepa kwa nyama.Ethylene glycol imasakanikirana ndi madzi ndi acetone, koma imasungunuka pang'ono mu ethers.Amagwiritsidwa ntchito ngati zosungunulira, antifreeze ndi zopangira za polyester yopanga.Polyethylene glycol (PEG), polima wa ethylene glycol, ndi gawo-transfer catalyst ndipo amagwiritsidwanso ntchito kuphatikizika kwa selo;esters ake a nitrate ndi mtundu wa kuphulika.
Ntchito Yogulitsa:
1.Mainly ntchito kupanga poliyesitala, poliyesitala, poliyesitala utomoni, hygroscopic wothandizira, plasticizers, surfactants, kupanga ulusi, zodzoladzola ndi mabomba, ndipo ntchito monga zosungunulira utoto, inki, etc., yokonza antifreeze kwa injini, gasi dehydrating wothandizira, kupanga utomoni, komanso ntchito cellophane, ulusi, zikopa, zomatira, wettability wothandizira.Itha kupanga PET yopangira utomoni, fiber grade PET yomwe ndi polyester fiber, PET grade grade kupanga mabotolo amchere amchere ndi zina zotero.Itha kutulutsanso utomoni wa alkyd, glyoxal, ndi zina. Amagwiritsidwanso ntchito ngati antifreeze.Kuphatikiza pa kugwiritsidwa ntchito ngati antifreeze pamagalimoto, imagwiritsidwanso ntchito poyendetsa kuzizira kwa mafakitale, ndipo nthawi zambiri imatchedwa carrier refrigerant, panthawiyi, itha kugwiritsidwanso ntchito ngati condenser ngati madzi.
2.Glycol methyl etha mndandanda mankhwala ndi apamwamba mlingo organic zosungunulira ndi ntchito kwambiri, ntchito monga zosungunulira ndi diluents kwa inki kusindikiza, mafakitale kuyeretsa wothandizila, utoto (nitrofibre utoto, vanishi, lacquers), matabwa mkuwa cladding, utoto ndi kusindikiza, etc. ;angagwiritsidwe ntchito ngati zipangizo kupanga intermediates mankhwala, mankhwala intermediates, ndi kupanga ananyema madzi ndi mankhwala ena mankhwala;amagwiritsidwa ntchito ngati electrolyte mu electrolytic capacitors, ndipo ngati wodaya wopangira zikopa ndi ulusi wamankhwala, etc. Amagwiritsidwanso ntchito ngati zida zothandizira nsalu, utoto wamadzimadzi opangira, ndi zida zopangira desulphurising popanga feteleza ndi malo opangira mafuta.
Zolemba Zosungira:
Khalani pamalo ozizira ndi owuma.
