I-Ethylene glycol CAS 107-21-1 isithekelisi

Incazelo emfushane:

I-Ethylene glycol iyinhlanganisela yemvelo enefomula (CH2OH)2.Isetshenziselwa ikakhulukazi izinhloso ezimbili, njengempahla eluhlaza lapho kwakhiwa imicu ye-polyester kanye nokwakhiwa kwe-antifreeze.Iwuketshezi olungenaphunga, olungenambala, olunambitheka kamnandi, olunama-viscous.

Isicelo somkhiqizo

1. I-ejenti yokupholisa neyokudlulisa ukushisa:Ukusetshenziswa okukhulu kwe-ethylene glycol kufana ne-antifreeze ejenti endaweni epholile njengesibonelo, ezimotweni nezinhlelo zokupholisa umoya.

2. I-anti-freeze:Isetshenziswa njengoketshezi lokususa uqweqwe lwe-icing kumawindshieldi nasezindizeni, njengesinqamuleli sokuqanda ezinjinini zezimoto.

3. Isandulela sama-polymers:Embonini yepulasitiki, i-ethylene glycol iyisandulela esibalulekile semicu ye-polyester nama-resin.I-Polyethylene terephthalate, esetshenziselwa ukwenza amabhodlela epulasitiki eziphuzo ezithambile, ilungiswa kusuka ku-ethylene glycol.

4. I-ejenti yokuqeda amanzi emzimbeni:Isetshenziswa embonini yegesi yemvelo ukususa umhwamuko wamanzi kugesi yemvelo ngaphambi kokucubungula okwengeziwe.

5. Ukuvimbela amanzi:Isetshenziselwa ukuvimbela ukwakheka kwegesi yemvelo clathrates (hydrates).
