Zatsopano Zotentha Zogulitsa Polyimide Resin Material Pyromellitic Dianhydride Pmda CAS 89-32-7
Pogwiritsa ntchito njira yabwino kwambiri yoyendetsera zinthu, khalidwe labwino komanso chipembedzo chabwino kwambiri, timapeza mbiri yabwino ndipo timagwiritsa ntchito njira imeneyi ya Hot New Products Supply Polyimide Resin Material Pyromellitic Dianhydride Pmda CAS 89-32-7, Labu yathu tsopano ndi "Labu Yadziko Lonse yaukadaulo wa injini ya dizilo ya turbo", ndipo tili ndi gulu la akatswiri ofufuza ndi chitukuko komanso malo oyesera kwathunthu.
Pogwiritsa ntchito njira yabwino kwambiri yoyendetsera zinthu, khalidwe labwino komanso chipembedzo chabwino kwambiri, timapeza mbiri yabwino ndipo timagwira ntchito imeneyi. Cholinga cha kampani yathu ndikupereka zinthu zabwino komanso zokongola pamtengo wabwino komanso kuyesetsa kupeza mbiri yabwino 100% kuchokera kwa makasitomala athu. Tikukhulupirira kuti ntchitoyo imakwaniritsa zabwino kwambiri! Tikukulandirani kuti mugwirizane nafe ndikukulira limodzi.
Pyromellitic dianhydride (yofupikitsidwa ngati PMDA), yomwe imagwiritsidwa ntchito makamaka popanga polyimide, chifukwa polyimide ili ndi kukana kutentha kwambiri, kukana asidi ndi alkali, yabwino kwambiri Chifukwa cha mphamvu zake zamakaniko, mphamvu zamagetsi komanso kukhazikika kwa magawo, imagwiritsidwa ntchito kwambiri m'magawo apamwamba monga ndege, ndege, ma microelectronics ndi mphamvu ya atomiki, zomwe zimakhala ndi zofunikira kwambiri pazinthu zakuthupi.

Pyromellitic dianhydride (PMDA) ndi chinthu chofunikira kwambiri pakupanga zinthu zachilengedwe, komanso chinthu chofunikira kwambiri popanga zinthu zatsopano zamakemikolo ndi zinthu zabwino kwambiri. Chimagwiritsidwa ntchito kwambiri popanga ma polyimide monomers, ndipo chingagwiritsidwenso ntchito ngati chothandizira kuchiritsa ma epoxy resin ndi chothandizira kulumikiza ma polyester resin, chomwe chimagwiritsidwa ntchito popanga utoto wabuluu wa phthalocyanine ndi zinthu zina zofunika, ndi zina zotero, ndipo chimagwiritsidwa ntchito m'njira zosiyanasiyana. Pyromellitic dianhydride, yomwe imadziwikanso kuti homoanhydride, ili ndi kapangidwe kapadera ka mamolekyulu ndipo ingagwiritsidwe ntchito kupanga zinthu zomwe zimakana kutentha, kutchinjiriza magetsi komanso kukana mankhwala, zomwe zimagwiritsidwa ntchito kwambiri ngati polyimide monolayer. Imapangidwa ndi aromatic diamine kuti ipange polyimide plastic, koma kuyera kwa pyromellitic dianhydride ndi kwakukulu kwambiri, komwe kuyenera kukhala kopitilira 99%.

Pogwiritsa ntchito njira yabwino kwambiri yoyendetsera zinthu, khalidwe labwino komanso chipembedzo chabwino kwambiri, timapeza mbiri yabwino ndipo timagwiritsa ntchito njira imeneyi ya Hot New Products Unilong Factory Supply Polyimide Resin Material Pyromellitic Dianhydride Pmda CAS 89-32-7, Labu yathu tsopano ndi "Labu Yadziko Lonse yaukadaulo wa injini ya dizilo ya turbo", ndipo tili ndi gulu la akatswiri ofufuza ndi chitukuko komanso malo oyesera kwathunthu.
Zogulitsa Zatsopano Zotentha Kwambiri Zoyera Kwambiri ndi Pmda Yokonzedwa Bwino Kwambiri, Cholinga cha kampani yathu ndikupereka zinthu zapamwamba komanso zokongola pamtengo wabwino komanso kuyesetsa kupeza mbiri yabwino 100% kuchokera kwa makasitomala athu. Tikukhulupirira kuti Katswiriyu amakwaniritsa zabwino kwambiri! Tikukulandirani kuti mugwirizane nafe ndikukulira limodzi.
