Khoom siv

1. Coolant thiab heat-transfer agent:Kev siv loj ntawm ethylene glycol yog ib qho tshuaj tiv thaiv kab mob hauv lub tshuab ua kom txias, piv txwv li, tsheb thiab tshuab cua txias.

2. Anti-freeze:Siv los ua cov kua dej de-icing rau lub tshuab cua thiab lub dav hlau, ua cov tshuaj tiv thaiv kab mob hauv tsheb.

3. Precursor rau polymers:Hauv kev lag luam yas, ethylene glycol yog ib qho tseem ceeb ua ntej rau polyester fibers thiab resins.Polyethylene terephthalate, siv los ua lub raj mis yas rau cov dej qab zib, yog npaj los ntawm ethylene glycol.

4. Dehydrating agent:Siv rau hauv kev lag luam roj av kom tshem tawm cov dej vapor los ntawm cov nkev roj ua ntej ua haujlwm ntxiv.

5. Hydrate inhibition:Siv los tiv thaiv kev tsim cov roj clathrates (hydrates).
