3,3 ', 4'-BiphenyltetRARBOXYYICY BININHYDRIDE CAS: 2420-87-3 3

Umsebenzi

I-3,3 ', 4'-BiphenyltetracBoxexyylic dianhydride (BPDA)kungumkhawulo obalulekile ekuhlolweni kwe-organic futhi unezicelo ezahlukahlukene:

Synthesis polymide

• Amafilimu asebenza kakhulu: Kungabhekana nokusabela kwe-polycondenation ngamakhompiyutha e-diamene ukukhiqiza amafilimu e-polymide. Lawa mafilimu anokumelana okuhle kakhulu kwezinga lokushisa. Noma endaweni yokushisa ephezulu ngenhla kwama-200 ° C, asakwazi ukugcina izakhiwo ezinhle zemishini kanye nokufakelwa kukagesi. Ngakho-ke, zivame ukusetshenziselwa insimu ye-aerospace yokuvikelwa kwezinto ezifakayo zama-motors kanye nemishini kagesi noma njengezinto eziyisisekelo zamabhodi wesifunda axhumene nezimo.
• I-Engineering Plastics: Amapulasitiki we-Polthesside Engineerics anamandla aphezulu, ubulukhuni obuhle, futhi futhi agqoke - agqoke. Bangakwazi ukudweba imijondolo ukuze bakha izingxenye ezithile ezinembile ngezidingo eziqinile zezakhiwo zemishini, njengamabakaki amancane azungeze izinjini zezindiza nezingxenye zokudlulisela ngaphakathi kwamawashi angena ngaphakathi.
• Inkambu ye-Coating: I-Polymide Coatings eyenziwe ngokusekelwe ku-BPDA ivelele ukumelana kwamakhemikhali. Uma isetshenziswa ezindongeni zangaphakathi zamathangi okugcina amakhemikhali nama-reactors, zingamelana nokuguguleka kwama-acid ahlukahlukene, izisekelo, kanye nezinto eziphilayo isikhathi eside, ziqinisekisa impilo yenkonzo yemishini. Ngasikhathi sinye, banokumelana nokushisa okuhle. Lapho ehlanganiswe kumapayipi okushisa okushisa aphezulu kanye nokukhangwa kwenjini, ngeke baphuze kalula ngenxa yokushisa okuphezulu.
• Izinto zefiber: Kusetshenziselwa ukwenza imicu yokusebenza okuphezulu. Imicu ye-polymide ekhiqizwa inamandla aphezulu, i-modulus ephezulu, nokuqina okuhle kakhulu okushisayo. Imvamisa isetshenziselwa ukukhiqiza amasudi okushisa umlilo, izintambo ezikhethekile ze-aerospace, njll., Ukuhlinzeka ngokuvikelwa okuthembekile kwabasebenzi nemishini yokushisa ephezulu kanye nezimo ezinobungozi obukhulu.

Ukupakisha nokuthumela

I-20KG / DRUM noma njengezidingo zamakhasimende.
Kungokwezimpahla ezijwayelekile futhi kungahambisa ngo-Ocean nomoya

Gcina futhi ugcine

I-Shelf Life: Inyanga engama-24 kusukela ngosuku lokwenziwa ekuphaketheni kwasekuqaleni okungavunyelwe okugcinwe endaweni epholile eyomile ngaphandle kokukhanya kwelanga, amanzi.
I-Warehouse evutha umoya, ukomisa okushisa okuphansi, okuhlukaniswe nama-oxidants, ama-acid.
