MEG (Mono Ethylene Glycol) Kev Siv Tshuaj
Polyester Kev Lag Luam:
- PET Resins: Ethylene Glycol (EG) yog cov khoom siv raw rau PET ntau lawm -reacting nrog terephthalic acid los ua PET resins siv nyob rau hauv lub hwj yas, ntim khoom noj, thiab textile fibers. Tshaj li 60% ntawm MEG thoob ntiaj teb cov khoom siv tau siv hauv kev tsim PET.
- Polyester Fibers: Siv los ua polyester staple fibers thiab filaments, dav siv nyob rau hauv khaub ncaws, tsev textiles, thiab industrial fabrics.
Antifreeze & Coolant: Formulated rau hauv automotive thiab industrial antifreezes/coolants; txo qis qhov dej khov ntawm dej thiab nce qhov kub ntawm qhov kub, tiv thaiv lub cav lossis cov khoom puas tsuaj los ntawm khov rau lub caij ntuj no thiab overheating nyob rau lub caij ntuj sov.
Chemical Synthesis: Siv nyob rau hauv kev tsim cov diethylene glycol, triethylene glycol, thiab lwm yam glycol ethers.
Lwm yam kev siv:
Hauv kev lag luam ntawv, raws li tus neeg sawv cev softening los txhim kho daim ntawv yooj; nyob rau hauv tawv ua, raws li ib tug humectant los tiv thaiv cracking; kuj tseem siv nyob rau hauv hydraulic kua thiab deicing agents.
