Incazelo
I-Mono ethylene glycol iyinhlanganisela yezinto eziphilayo enefomula yamakhemikhali (CH2OH)2. esetshenziswa kakhulu njengezinto zokusetshenziswa ekukhiqizeni i -polyester fiber kanye nezindlela zokuvimbela ukuqandisa . I-MEG yaqala ukukhiqizwa yisokhemisi saseFrance. Ngokuhamba kwesikhathi, ngenxa yezakhiwo ezifiselekayo zalesi sinyibilikisi , njengamandla aphezulu kanye nokungabanda kwamanzi, ukusetshenziswa kwaso kuye kwanda kakhulu.
Isicelo
I-Ethylene glycol iyinhlanganisela yezimboni ewusizo etholakala emikhiqizweni eminingi yabathengi. Izibonelo zifaka phakathi i-antifreeze, uketshezi lwamabhuleki e-hydraulic, ama-inki athile e-stamp pad , amapeni e-ballpoint, izinyibilikisi, upende, ipulasitiki, amafilimu.
I-ejenti epholisayo neyokudlulisa ukushisa
Ukusetshenziswa okukhulu kwe-ethylene glycol kufana ne-antifreeze ejenti endaweni epholile.
Ukumisa okokuqandisa
I-ethylene glycol ehlanzekile iba yiqhwa cishe ku-−12 °C (10.4 °F) kodwa, lapho ixutshwa namanzi, ingxube iba yiqhwa ezingeni lokushisa eliphansi.Ngenxa yamazinga okushisa abandayo acindezelayo, i-ethylene glycol isetshenziswa njengoketshezi olususa uqweqwe lweqhwa kumawindi omoya nendiza, njengesinqanda-qhwa ezinjinini zezimoto.
