3,3′,4,4′-Biphenyltetracarboxylic dianhydride CAS: 2420-87-3 3

Imikoreshereze

3,3',4,4'-Biphenyltetracarboxylic dianhydride (BPDA)ni ingenzi mu guhuza imikorere y’ibinyabuzima kandi ifite uburyo bwinshi bwo kuyikoresha:

Ikorwa rya poliimide

• Filimi zifite imikorere myiza: Zishobora kunyura mu buryo bwa polycondensation hamwe n’ibinyabutabire bya diamine kugira ngo zikore filime za polyimide. Izi filime zifite ubushobozi bwo kurwanya ubushyuhe bwinshi. Ndetse no mu bushyuhe buri hejuru ya 200 °C, zishobora gukomeza kugira imiterere myiza ya mekanike n’ubushyuhe bw’amashanyarazi. Kubwibyo, zikunze gukoreshwa mu rwego rw’indege mu kurinda ubushyuhe bwa moteri n’ibikoresho by’amashanyarazi cyangwa nk'ibikoresho by'ibanze ku mbaho ​​zoroshye zacapwe.
• Plastike z'ubwubatsi: Plastike z'ubwubatsi za polyimide zikozwe mu buryo bwa pulasitiki zifite imbaraga nyinshi, ziramba neza, kandi ntizipfa kwangirika. Zishobora gushingwa mu buryo bwa pulasitiki kugira ngo zikore ibice bimwe na bimwe bifite ibisabwa cyane ku miterere ya mashini, nk'udukingirizo duto dukikije moteri z'indege n'ibice byo kohereza ibintu mu masaha ya mashini agezweho.
• Aho gutwikira: Imyambaro ya polyimide ikorwa hashingiwe kuri BPDA ifite ubushobozi bwo kurwanya ingese. Iyo ishyizwe ku nkuta z'imbere z'ibigega byo kubikamo imiti n'ibikoresho bya réaktori, ishobora kurwanya isuri ya aside zitandukanye, bases, na organic solvents igihe kirekire, bigatuma ibikoresho bimara igihe kirekire. Muri icyo gihe, ifite kandi ubushobozi bwo kurwanya ubushyuhe. Iyo ishyizwe ku miyoboro isohora umwuka irimo ubushyuhe bwinshi n'udusanduku twa moteri, ntabwo izigera icika byoroshye kubera ubushyuhe bwinshi.
• Ibikoresho bya fibre: Ikoreshwa mu gukora fibre zikora neza cyane. Fibre za polyimide zikorwa zifite imbaraga nyinshi, modulus nyinshi, kandi zituma ubushyuhe buhora buhagaze neza. Akenshi zikoreshwa mu gukora imyenda idashya, imigozi yihariye yo mu kirere, nibindi, zitanga uburinzi bwizewe ku bakozi n'ibikoresho mu bihe by'ubushyuhe bwinshi n'ibyago byinshi.

Gupakira no Kohereza

20KG/Ingoma cyangwa nk'uko umukiriya abikeneye.
Ni iy'ibicuruzwa rusange kandi ishobora gutangwa binyuze mu nyanja no mu kirere

Bika kandi ubibike

Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
