1,2,4-Benzenetricarboxylicanhydride CAS:552-30-7

I-1,2,4-Benzenetricarboxylic anhydride (BTCA) isebenza imisebenzi emininzi kumashishini ahlukeneyo ngenxa yeempawu zayo ezahlukeneyo. Kwicandelo le-polymer chemistry, isebenza njenge-arhente yokudibanisa kunye ne-monomer ephendulayo ekuvelisweni kwee-thermoset resins, ezifana ne-polyester kunye ne-epoxy resins. Ezi resins zifumana ukusetyenziswa kwiingubo, izincamathelisi, ii-composites, kunye nee-molding compounds, zinegalelo ekuphuculeni amandla ezinto, ukumelana nobushushu, kunye nokuqina kweekhemikhali. Ngaphezu koko, i-BTCA isetyenziswa ekuvelisweni kwee-polymers ezisebenzayo eziphezulu ezifana nee-polyimides, apho isebenza njengebhloko yokwakha ephambili. Ukufakwa kwayo kwiityathanga ze-polymer kuphucula uzinzo lwazo lobushushu, amandla oomatshini, kunye neempawu ze-dielectric, okwenza ukuba ifaneleke ukusetyenziswa kwi-elektroniki, kwi-aerospace, nakwiifilimu ezikhethekileyo. Ekuqulunqweni kweengubo kunye nee-linings ezimelana nokugqwala, i-BTCA idlala indima ebalulekileyo njenge-arhente yokulungisa kunye ne-crosslinker. Xa idityaniswe neenkqubo ze-epoxy okanye ze-polyurethane, iphucula ukumelana kweekhemikhali kunye nokunamathela kweengubo ezisetyenziselwa ukukhusela umphezulu wesinyithi kwizicelo zaselwandle, kwimizi-mveliso, nakwiziseko zophuhliso. Ngaphezu koko, isetyenziswa njenge-arhente ye-chelating kwiinkqubo zonyango lwamanzi. Amandla ayo okususa ii-ion zesinyithi anceda ekuthinteleni ukwakheka kwesikali kunye nokugqwala kwiinkqubo zokusasazwa kwamanzi, okufaka isandla ekuphuculeni umgangatho wamanzi kunye nexesha elide leziseko. Ukongeza, i-BTCA isebenza njengophawu lokuqala ekuhlanganisweni kwezinto ezidityanisiweyo zamayeza kunye neekhemikhali ezikhethekileyo. Ukusebenza kwayo kunye namaqela asebenzayo kuyenza ibe luncedo ekuphuhlisweni kweekhompawundi zeekhemikhali ezenzelwe iimfuno ezithile zoshishino kunye nezamayeza. Ngaphezu koko, isetyenziswa ekuveliseni izinto ezithintela ilangatye kunye nezongezo ezimelana nobushushu zeplastiki kunye neendwangu, inegalelo ekuphuculeni ukhuseleko lomlilo kunye nokuzinza kobushushu kwizicelo ezahlukeneyo zabathengi kunye nezemizi-mveliso. Ngokubanzi, izicelo ezahlukeneyo ze-1,2,4-benzenetricarboxylic anhydride ziquka i-polymer chemistry, ii-polymers ezisebenzayo eziphezulu, iingubo ezimelana nokugqwala, unyango lwamanzi, amayeza, izinto ezithintela ilangatye, kunye neekhemikhali ezikhethekileyo. Iimpawu zayo eziguquguqukayo zinegalelo ekuphuculeni ukusebenza kwezinto, ukukhusela ekuwohlokeni, kunye nokwenza kube lula ukuveliswa kwezinto eziphambili kumashishini amaninzi.
