Indawo yokubilisa ye-Ethylene Glycol kanye nokuhlaziywa kwempahla yamakhemikhali
Embonini yamakhemikhali, i-ethylene glycol (i-Ethylene Glycol) iyinto ebalulekile yamakhemikhali eluhlaza esetshenziswa kabanzi emikhakheni ehlukahlukene efana ne-antifreeze kanye nokukhiqizwa kwe-resin. Ukuqonda izici ze-physicochemical ye-Ethylene Glycol, ikakhulukazi indawo yayo yokubilisa, kubalulekile ekusebenziseni kwayo embonini. Kulesi sihloko, iphuzu elibilisayo le-ethylene glycol kanye nezici zayo ezithonya ezihlobene kuzoxoxwa ngakho ngokuningiliziwe.
Izakhiwo Eziyisisekelo Ze-Ethylene Glycol kanye Nendawo Yokubilisa
I-Ethylene glycol iwuketshezi lwe-viscous olungenambala, olungenaphunga, olunuka kamnandi olunefomula yamakhemikhali ethi C₂H₆O₂. Njenge-diol, i-ethylene glycol ine-hygroscopicity eqinile kanye nezakhiwo ezinhle zokuncibilika. Iphuzu elibilayo le-ethylene glycol lingu-197.3°C. Leli nani, elilinganiswa ngomfutho womkhathi, libonisa ukuzinza kwesakhiwo sayo samangqamuzana namandla amabhondi ayo e-hydrogen aphakathi kwamamolekyuli.
Izinto ezithinta indawo yokubilisa kanye nokubaluleka kwemboni
Iphuzu lokubilisa le-ethylene glycol lithonywa izici eziningi. Ukuhlanganiswa kwe-hydrogen esakhiweni samangqamuzana kunomphumela ophawulekayo endaweni yokubilisa. I-molecule ye-ethylene glycol iqukethe amaqembu amabili e-hydroxyl (-OH), axhunywe ngamabhondi e-hydrogen, okwenza amandla e-intermolecular ethylene glycol aqine futhi aholele endaweni yokubilisa ephakeme kakhulu. Isisindo samangqamuzana e-ethylene glycol siphinde sithinte indawo yayo yokubilisa, ngezisindo zamangqamuzana ezinkulu ezidinga amandla engeziwe okuhwamuka.
Ekusetshenzisweni kwezimboni, indawo yokubilisa ye-ethylene glycol inomthelela omkhulu ekusebenzeni kwayo njenge-solvent, i-coolant neminye imikhiqizo. Isibonelo, indawo yokubilisa ephezulu yenza i-glycol izinze futhi ingaguquguquki kakhulu emazingeni okushisa aphezulu, ngaleyo ndlela iqinisekise ukusebenza kahle kwayo ezintweni ezipholile kanye ne-antifreeze.
Izinyathelo zokuqapha ekusebenziseni okungokoqobo
Uma usebenzisa i-ethylene glycol, ukunakwa kufanele kukhokhwe ekusebenzelaneni kwephuzu layo lokubilisa nezinye izinto. Isibonelo, kuma-composites noma izixazululo ezixubile, ezinye izinto zingase zithinte iphuzu lokubilisa le-ethylene glycol futhi ngaleyo ndlela izakhiwo zokugcina zomkhiqizo. Ulwazi lwephuzu lokubilisa le-ethylene glycol lungasiza futhi ekwandiseni izinqubo zokukhiqiza ezimbonini, njengokulawula izinga lokushisa ngesikhathi sokukhipha isisu nokugxilisa ingqondo.
Kafushane, ukuqonda iphuzu lokubilisa le-ethylene glycol kubalulekile ekusebenzeni kwayo kwezimboni. Ngokuqonda le mpahla ebonakalayo ye-ethylene glycol, ukusebenza kwayo ekukhiqizeni nasekusetshenzisweni kwayo kungalawulwa kangcono ukuthuthukisa ikhwalithi nokuzinza komkhiqizo.
