Ethylene Glycol (MEG) ya Aojin Chemical ikukwezedwa ndikutumizidwa! Kodi ntchito zofala za ethylene glycol ndi ziti?
Ethylene glycol (MEG)ndi chinthu chofunikira kwambiri chopangira mankhwala, ndipo ntchito zake zazikulu zimagwiritsidwa ntchito m'magawo otsatirawa:
1. Kupanga kwa polyester ndiko kugwiritsa ntchito kwakukulu kwa ethylene glycol, komwe kumabweretsa kugwiritsidwa ntchito kwakukulu:
Ethylene glycol imakumana ndi terephthalic acid (PTA) kudzera mu polycondensation kuti ipange polyethylene terephthalate (PET), yomwe imagwiritsidwa ntchito popanga ulusi wa polyester (monga polyester, yomwe imagwiritsidwa ntchito mu nsalu ndi zovala), ma polyester resins (omwe amagwiritsidwa ntchito m'mabotolo apulasitiki, zotengera zopakitsira, ndi zina zotero), komanso mafilimu ndi mapulasitiki aukadaulo.
2. Ethylene glycol yoletsa kuzizira ndi yoziziritsa ndi njira ina yofunika kwambiri yogwiritsira ntchito. Chifukwa cha kuzizira kwake kochepa komanso kutentha kwake kokhazikika, nthawi zambiri imagwiritsidwa ntchito mu zoziziritsa injini zamagalimoto (zoletsa kuzizira), makina ochotsera icing mu ndege, komanso ngati choziziritsira mu nthawi yozizira m'mafakitale.
3. Udindo wa solvent ndi wapakati:Ethylene glycolingagwiritsidwe ntchito ngati chosungunulira cha zokutira, inki, utoto, ndi utomoni, komanso ngati chothandizira pakupanga zinthu zosiyanasiyana za mankhwala, monga popanga zinthu zosungunulira, zopaka pulasitiki, ndi mafuta odzola.
Ntchito zina zamafakitale zimaphatikizapo monga chonyowetsa mpweya, choyeretsera mpweya, chochotsera madzi m'magesi (monga pokonza gasi lachilengedwe), komanso ngati chonyowetsa kapena chosinthira kukhuthala kwa khungu mu zodzoladzola.
