CAS 107-21-1 Monethylene Glycol (MEG)yog ib qho ntawm cov khoom tseem ceeb tshaj plaws hauv kev lag luam chemical thiab petrochemical, ua lub luag haujlwm tseem ceeb hauv kev tsim cov polyethylene terephthalate (PET), polyester, thiab hluavtaws fibers. Vim nws cov khoom siv tshuaj lom neeg tshwj xeeb, MEG tau dav siv tsis yog hauv kev lag luam textile nkaus xwb, tab sis kuj tseem siv hauv kev tsim cov raj mis PET, ntim cov yeeb yaj kiab, thiab txawm tias cov tshuaj tiv thaiv kab mob. Nrog kev loj hlob thoob ntiaj teb kev thov, ntau dua 59% ntawm lub ntiaj teb MEG ntau lawm yog mob siab rau polyester fiber ntau lawm.
Kev siv tseem ceeb ntawm Monoethylene Glycol hauv PET Resin Production
Txog70% ntawm thoob ntiaj teb MEG ntau lawmyog siv los ua polyester thiab PET resins. Yog tsis muaj MEG, ntau yam khoom siv niaj hnub xws li khaub ncaws kis las, lub raj mis dej ntxhia, thiab ntim cov yeeb yaj kiab tsis tuaj yeem tsim tawm.
Polymerisation intermediates: Mono Ethylene Glycol MEG yog lub hauv paus tsev thaiv uas ua ke nrog PTA / DMT los ua ib qho ntev - saw polyester polymers. Nws yog ib qho tseem ceeb raw khoom nyob rau hauv synthesis ntawm PET resin.
PET resin ntau lawm: Monoethylene Glycol yog siv ncaj qha los tsim polyethylene terephthalate (PET) resin, uas yog siv dav hauv kev tsim cov pob tshab thiab glossy fwj rau zaub mov, dej haus thiab tshuaj pleev ib ce.
Polyester fiber ntau manufacturing: MEG yog siv los ua ib qho tseem ceeb, siab -purity tivthaiv los tsim polyester fibers rau textiles, imparting zog, durability thiab wrinkle kuj.
Kev hloov kho kev ua haujlwm (PETG): Hauv cov ntawv thov tshwj xeeb, MEG txhim kho qhov cuam tshuam tsis kam, yoog raws thiab thermal stability los ntawm kev hloov kho cov qauv polymer.
Kev tswj cov txheej txheem: Nws pab kom ntseeg tau tias PET zoo ib yam, uas yog qhov tseem ceeb rau kev ua tau zoo molding thiab kev tsim khoom.
Raws li kev ntseeg siab siab -Purity Ethylene Glycol EG/MEG cov chaw tsim khoom thiab cov chaw muag khoom, peb muab Monoethylene Glycol (CAS 107-21-1) nrog kev tswj xyuas nruj, ruaj khov ntim khoom loj, thiab cov ntaub ntawv xa tawm thoob ntiaj teb rau cov neeg yuav khoom.
