Tšebeliso
E 'ngoe ea litšobotsi tse ka sehloohong le tšebeliso ea ethylene glycol ke ho feto-fetoha ha eona e le solvent.E le solubilizer e tšepahalang le e sebetsang hantle, e sebelisoa haholo liindastering tse fapaneng.Bokhoni ba eona ba ho qhaqha mefuta e mengata ea lintho bo etsa hore e be motsoako oa bohlokoa haholo tlhahisong ea li-polyester tsa maiketsetso.Hore na o hloka ho qhaqha lidae, meriana kapa lintho tse ling, li-glycols li fana ka solvency e phahameng ho netefatsa litholoana tse ntle bakeng sa ts'ebetso ea hau ea tlhahiso.
Ntho e 'ngoe e hlokomelehang ea ethylene glycol ke karolo ea eona e le antifreeze.Ka sebaka sa eona se tlaase sa leqhoa, se thibela leqhoa ho thekesela ka har'a tsamaiso ea ho tsidifatsa, e leng se etsang hore e be motsoako oa bohlokoa haholo mekhoeng e thibelang leqhoa ea likoloi.Karolo ena e netefatsa hore enjene ea hau le sistimi ea ho pholisa li tla lula li sebetsa le maemong a mocheso a tlase ho zero.Ho feta moo, chefo ea eona e tlase ho liphoofolo e tiisa ts'ebeliso e bolokehileng lits'ebetsong tsa indasteri le malapeng.
Ethylene glycol e bapala karolo ea bohlokoa lihlahisoa tse tala bakeng sa ho qaptjoa ha polyester.Ke thepa ea motheo bakeng sa tlhahiso ea polyester 'me e na le botsitso bo botle ba mocheso le thepa ea mechine.Ho sa tsotellehe hore na u hloka likhoele tsa maiketsetso, lifilimi kapa li-resin, li-glycols li fana ka motheo oa ho theha lisebelisoa tse sebetsang hantle tse finyellang litlhoko tse fapaneng tsa liindasteri tse sa tšoaneng.
Ka kakaretso, ethylene glycol ke motsoako o sebetsang ka bongata o nang le lisebelisoa tse ntle tsa solvency le antifreeze, 'me ke thepa ea bohlokoa e tala tlhahisong ea li-polyester tsa maiketsetso.Sebopeho sa eona se se nang 'mala, se se nang monko, hammoho le chefo e tlase ho liphoofolo, se netefatsa polokeho le katleho ts'ebelisong ea hau.Glycol e tsoakana ntle le moroallo le metsi le acetone, e e etsa tharollo e phethahetseng bakeng sa litlhoko tsa hau tsa solvent le antifreeze.Fumana melemo e phahameng ea ethylene glycol 'me u nke mokhoa oa hau oa ho etsa lihlahisoa holimo.
