mono ethylene glycol siv
Polyester qib MEG yog qhov yuav tsum tau ua rau PET ntau lawm, qib kev lag luam yog siv los tiv thaiv khov, thiab qib txuj ci tsim nyog rau tus nqi -sensitive non- daim ntawv thov tseem ceeb.
- Polyester qib MEG (Ntau dua lossis sib npaug li 99.9%) yog xav tau rau PET fiber ntau, zaj duab xis, thiab lub raj mis ntau lawm vim yog qhov yuav tsum tau ua kom huv huv thiab tsis muaj dej noo (<0.05%).
- Muaj qib MEG (Ntau dua lossis sib npaug li 99.0%) feem ntau yog siv rau hauv cov tsheb tiv thaiv kab mob uas cov qauv tiv thaiv corrosion thiab thermal stability txaus.
- Kev kawm qib MEG (98–99%) yog qhov tsim nyog rau kev siv tsis yog- tseem ceeb hauv kev lag luam xws li roj lub cev qhuav dej thiab deicing, qhov kev ua tau zoo ntawm tus nqi yog qhov tseem ceeb tshaj ultra- siab purity.
