intengo ephansi yasefektri 3, 3′ , 4, 4′ -Benzophenonetetracarboxylic Dianhydride CAS: 2421-28-5
Inkampani yethu ithembisa bonke abantu abavela ezimpahleni ezisezingeni eliphezulu kanye nenkampani eyanelisa kakhulu ngemuva kokuthengiswa. Siyabamukela ngemfudumalo abathengi bethu abavamile nabasanda kuqala ukuthi bazojoyina nathi.intengo ephansi yefektri 3, 3′ , 4, 4′ -Benzophenonetetracarboxylic Dianhydride I-CAS: 2421-28-5Siyakwamukela ngobuqotho ukuthi uzofika kithi. Ngiyethemba ukuthi manje sizoba nokubambisana okuhle kakhulu ngesikhathi esizayo.
Inkampani yethu ithembisa bonke abantu abavela ezimpahleni ezisezingeni eliphezulu kanye nenkampani eyanelisa kakhulu ngemuva kokuthengiswa. Siyabamukela ngemfudumalo abathengi bethu abavamile nabasanda kuthenga ukuthi bajoyine nathi. Ngaphezu kwalokho, sisekelwe ochwepheshe abanolwazi oluphezulu nabanolwazi, abanobuchwepheshe obukhulu emkhakheni wabo. Laba chwepheshe basebenza ngokubambisana ukuze banikeze amakhasimende ethu uhla lwezinto olusebenzayo.
3,3 ', 4,4′ – i-Benzophenonetetracarboxylic dianhydrideiyimpuphu ekristalu ensundu. Iphuzu lokuncibilika kwalesi sici lingu-218.67 ° C, futhi liyabola ku-360 ° C. Izinga lokushisa lokushisa elizenzakalelayo liphezulu kakhulu, futhi akukho ukusha okubonwe. Ubuningi besici bungu-1.5452g/ml, kanti ingcindezi yomhwamuko ingu-6.53E-011Pa.

I-BTDA isetshenziswa njengesikhungo sokukhiqiza imikhiqizo yepulasitiki noma amakhemikhali amahle emkhakheni wezimboni. I-polymer monomer, esetshenziselwa ukuhlanganisa izinto ze-polymer ezimelana nokushisa okuphezulu.
Ngokuvamile kupakishwe ku-25kg/isigubhu, futhi kungenziwa ngezifiso.
Inkampani yethu ithembisa bonke abantu abavela ezimpahleni ezisezingeni eliphezulu kanye nenkampani eyanelisa kakhulu ngemuva kokuthengiswa. Siyabamukela ngemfudumalo abathengi bethu abavamile nabasanda kuqala ukuthi bazojoyina nathi ngentengo ephansi efektri.3, 3′ , 4, 4′ -Benzophenonetetracarboxylic Dianhydride I-CAS: 2421-28-5Siyakwamukela ngobuqotho ukuthi uzofika kithi. Ngiyethemba ukuthi manje sizoba nokubambisana okuhle kakhulu ngesikhathi esizayo.
Intengo ephansi yefektri i-CAS: 2421-28-5 kanye ne-C17h6o7, Ngaphezu kwalokho, sisekelwe ochwepheshe abanolwazi oluphezulu nabanolwazi, abanobuchwepheshe obukhulu emkhakheni wabo. Laba ochwepheshe basebenza ngokubambisana ukuze banikeze amakhasimende ethu uhla lwezinto ezisebenzayo.
