Kev siv
Ib qho ntawm cov yam ntxwv tseem ceeb thiab kev siv ntawm ethylene glycol yog nws cov versatility raws li hnyav hnyav. Raws li ib tug txhim khu kev qha thiab npaum solubilizer, nws yog dav siv nyob rau hauv ntau yam lag luam. Nws muaj peev xwm ua kom yaj ntau yam khoom ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv hluavtaws polyesters. Txawm hais tias koj yuav tsum tau yaj dyes, tshuaj lossis lwm yam tshuaj, glycols muab cov kev daws teeb meem zoo tshaj plaws los xyuas kom meej cov txiaj ntsig zoo tshaj plaws rau koj cov txheej txheem tsim khoom.
Lwm qhov tseem ceeb ntawm ethylene glycol yog nws lub luag haujlwm los tiv thaiv kev khov. Nrog nws qhov qis qis qis, nws tiv thaiv cov dej khov los ntawm kev tsim cov cua txias, ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv hauv tsheb antifreeze formulations. Qhov no ua kom ntseeg tau tias koj lub cav thiab lub tshuab ua kom txias yuav nyob twj ywm txawm tias nyob rau hauv qis-zero kub. Tsis tas li ntawd, nws cov toxicity tsawg rau cov tsiaj guarantees kev nyab xeeb siv nyob rau hauv ob qho tib si industrial thiab domestic daim ntaub ntawv.
Ethylene glycol plays lub luag haujlwm tseem ceeb hauv cov khoom siv raw rau kev sib txuas ntawm polyester. Nws yog cov khoom siv yooj yim rau polyester ntau lawm thiab muaj cov thermal stability zoo thiab txhua yam khoom. Txawm hais tias koj xav tau cov fibers hluavtaws, cov yeeb yaj kiab lossis cov resins, glycols muab lub hauv paus rau kev tsim cov ntaub ntawv ua tau zoo uas ua tau raws li cov kev xav tau ntawm ntau yam kev lag luam.
Nyob rau hauv cov ntsiab lus, ethylene glycol yog ib tug multifunctional compound nrog zoo heev solvency thiab antifreeze zog, thiab yog ib qho tseem ceeb raw khoom nyob rau hauv zus tau tej cov hluavtaws polyesters. Nws qhov tsis muaj xim, tsis muaj ntxhiab tsw, ua ke nrog cov tshuaj lom neeg tsawg, ua kom muaj kev nyab xeeb thiab ua haujlwm zoo hauv koj daim ntawv thov. Glycol sib tov seamlessly nrog dej thiab acetone, ua rau nws zoo meej tov rau koj hnyav thiab antifreeze xav tau. Paub txog cov txiaj ntsig zoo tshaj ntawm ethylene glycol thiab coj koj cov txheej txheem tsim khoom mus rau qhov siab tshiab.
