Intshayelelo
I-4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid) yi-organic compound. Ingumgubo omhlophe we-crystalline kunye nokuzinza okuphezulu kwe-thermal kunye nokumelana nesimo sezulu.
I-compound ingasetyenziselwa ukulungiselela izinto eziphezulu ze-polyester ezinokumelana ne-oxidation ephezulu kunye nokumelana nobushushu, kwaye inoluhlu olubanzi lwezicelo. Ingasetyenziswa njengesilungisi ukuphucula iimpawu zepolyester, ezifana ne-ductility, amandla, kunye nokumelana nemozulu. Isenokusetyenziswa njenge-photosensitizer kunye ne-additive for polymerization catalysts.
Indlela yokulungiselela i-4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid) inzima kwaye idinga ukufunyanwa ngokusabela kwamanyathelo amaninzi. Indlela eqhelekileyo esetyenziswayo kukusabela i-phthalic acid kunye ne-methylene trifluoride phantsi kweemeko ze-alkaline ukunika i-4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid).
Ulwazi lokhuseleko: Iindlela ezifanelekileyo zokuphatha kunye nezilumkiso kufuneka zithathwe ngexesha lokulungiswa kunye nokusetyenziswa kwale khompawundi. Inetyhefu ethile kunye nokucaphuka, kwaye kufuneka ithintelwe ekusezeleni uthuli kwaye idibane nolusu, amehlo, njl.njl. Nxiba iiglavu ezikhuselayo, iimaski, kunye nezibuko ukuqinisekisa ukungena komoya okulungileyo ngexesha lokusebenza.
