Pyromellitic dianhydride(PMDA)
Pyromellitic Anhydride (PMDA) o se mea mataʻutia mo resini polyimide e teteʻe vevela, ata tifaga ma ufiufi.
O le PMDA e masani lava ona faʻaaogaina e avea o se vaeluaga mo ata tifaga polyimide faʻapea foʻi ma mea faʻapipiʻi faʻavae polyimide i laupapa faʻasalalau lolomi fetuutuunai, faʻapipiʻi faʻapipiʻi faʻapipiʻi, faʻamauina uaea maneta, ma isi.
talosaga maualuga faatinoga.
E faʻaaogaina foʻi e fai ma sui faʻamalolo mo resini epoxy o loʻo faʻaaogaina i paʻu paʻu (e gaosia ai vaega mo mama faʻamaufaʻailoga, faʻamau faʻamaʻi, gaskets faʻapitoa poʻo insulators vevela ma eletise), faʻapipiʻi ma ufiufi.
Shanghai Runwu Chemical Technology Co. Ltd o se oloa gaosi oloa gaosi oloa R & D, gaosiga, faʻatau, o se tasi o le mauaina.Matou te faʻalagolago i le malosi o suʻesuʻega ma tekinolosi matua, faʻavavevave le faʻaogaina o vailaʻau, faʻalagolago i le faasaienisi ma le atinaʻeina o tekonolosi, e tuʻuina atu i tagata faʻatau oloa tulaga maualuga o la matou sailiga faifaipea.
E masani lava ona matou feagai ma mea faʻale-aganuʻu, faʻapipiʻi uʻamea mamalu, mea faʻatau, eleele seasea.O nei mea e faʻaaogaina lautele i kemisi, vailaʻau, biology, puipuiga o le siosiomaga, malosi fou, ma isi.
Faatasi ai ma le tulaga muamua-vasega oloa tulaga lelei ma auaunaga faʻapitoa faʻapitoa, Ua matou manumalo i le viia o aganuʻu.I le taimi lava e tasi, i le atinaʻe, o loʻo tausisia e le matou kamupani le galulue faʻatasi ma kamupani faʻapitonuʻu ma fafo, faʻalapotopotoga suʻesuʻe faʻasaienisi, fesuiaiga o iunivesite, ina ia faʻaleleia atili le R & D ma le gaosiga gafatia, tuuto atu i le tuʻuina atu o tagata faʻatau oloa ma auaunaga sili atu.
