Aojin Chemical's Ethylene Glycol (MEG) tab tom raug thauj khoom thiab xa khoom! Cov kev siv ethylene glycol feem ntau yog dab tsi?
Ethylene glycol (MEG)yog ib qho khoom siv tshuaj lom neeg tseem ceeb, thiab nws cov kev siv tseem ceeb yog tsom mus rau cov hauv qab no:
1. Kev tsim cov polyester yog qhov tseem ceeb ntawm ethylene glycol, suav rau feem ntau ntawm nws cov kev siv:
Ethylene glycol reacts nrog terephthalic acid (PTA) los ntawm polycondensation los tsim polyethylene terephthalate (PET), uas tom qab ntawd siv los tsim cov polyester fibers (xws li polyester, siv rau hauv textiles thiab khaub ncaws), polyester resins (siv rau hauv lub raj mis yas, cov thawv ntim khoom, thiab lwm yam), nrog rau cov yeeb yaj kiab thiab cov yas engineering.
2. Cov tshuaj tiv thaiv kev khov thiab cov tshuaj txias yog lwm qhov kev siv tseem ceeb ntawm ethylene glycol. Vim nws qhov chaw khov qis thiab kev ruaj khov zoo, nws feem ntau siv rau hauv cov tshuaj txias cav tsheb (antifreeze), cov tshuab tshem dej khov hauv dav hlau, thiab ua cov tshuaj txias hauv cov voj voog tub yees hauv kev lag luam.
3. Lub luag haujlwm hnyav thiab nruab nrab:Ethylene glycolsiv tau ua cov kuab tshuaj rau cov tshuaj pleev xim, cov kua mem, cov xim pleev, thiab cov resins, thiab kuj yog ib qho nruab nrab rau kev tsim cov khoom siv tshuaj ntau yam, xws li hauv kev tsim cov surfactants, plasticizers, thiab cov roj nplua nyeem.
Lwm yam kev siv hauv kev lag luam suav nrog ua cov tshuaj humectant, desiccant, roj dehydrating agent (xws li hauv kev ua cov roj ntuj), thiab ua cov tshuaj moisturizer lossis viscosity modifier hauv cov tshuaj pleev ib ce.
