Mawu Oyamba
4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid) ndi organic pawiri. Ndi ufa wa crystalline woyera wokhala ndi kukhazikika kwapamwamba komanso kutentha kwa nyengo.
Pawiri angagwiritsidwe ntchito kukonzekera mkulu-ntchito polyester zipangizo ndi mkulu makutidwe ndi okosijeni kukana ndi kutentha kukana, ndipo ali osiyanasiyana ntchito. Itha kugwiritsidwa ntchito ngati chosinthira kukonza zinthu za polyester, monga ductility, mphamvu, komanso kukana kwanyengo. Itha kugwiritsidwanso ntchito ngati photosensitizer komanso chowonjezera cha polymerization catalysts.
Njira yokonzekera 4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid) ndi yovuta ndipo imayenera kupezedwa kudzera munjira zambiri. Njira yomwe imagwiritsidwa ntchito nthawi zambiri ndikuchita phthalic acid ndi methylene trifluoride pansi pamikhalidwe ya alkaline kupereka 4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid).
Chidziwitso chachitetezo: Njira zoyenera zogwirira ntchito ndi kusamala ziyenera kuchitidwa panthawi yokonzekera ndikugwiritsa ntchito pagululi. Lili ndi kawopsedwe kena kake ndi kuyabwa, ndipo liyenera kupewedwa pokoka fumbi ndikukhudzana ndi khungu, maso, ndi zina zambiri. Valani magolovesi oteteza, masks, ndi magalasi kuti mutsimikizire kuti mpweya wabwino ukugwira ntchito.
