Pyromellitic dianhydride(PMDA)
ʻO Pyromellitic Anhydride (PMDA) kahi mea maka no nā resins polyimide pale wela, nā kiʻiʻoniʻoni a me nā uhi.
Hoʻohana nui ʻia ʻo PMDA ma ke ʻano he waena no nā kiʻiʻoniʻoni polyimide a me nā mea hoʻohui i hoʻokumu ʻia i ka polyimide i loko o nā papa kaapuni paʻi paʻi ʻia, ka hoʻopaʻa ʻana i ka tape automated, insulation wire magnetic, a me nā mea ʻē aʻe.
nā noi hana kiʻekiʻe.
Hoʻohana ʻia ʻo ia ma ke ʻano he lāʻau lapaʻau no nā resins epoxy i hoʻohana ʻia i ka hoʻoheheʻe ʻana i nā pauka (e hana i nā ʻāpana no nā apo sila, nā mea holoi holoi, nā gaskets kūikawā a i ʻole nā mea wela a me nā uila), nā adhesives a me nā uhi.
ʻO Shanghai Runwu Chemical Technology Co. Ltd he huahana ʻoihana kemika R & D, hana, kūʻai aku, e like me kekahi o ka ʻike.Ke hilinaʻi nei mākou i ka hiki ke noiʻi ikaika a me ka ʻenehana makua, ke piʻi wikiwiki i ka ʻoihana kemika, e hilinaʻi ana i ka ʻepekema a me ka hoʻomohala ʻenehana, e hāʻawi i nā mea kūʻai aku me nā huahana kiʻekiʻe kā mākou ʻimi mau.
Kūleʻa nui mākou i nā mea waena organik, catalyst metal noble, nano material, rare earth.Hoʻohana nui ʻia kēia mau mea i ka kemika, lāʻau lapaʻau, biology, mālama kaiapuni, ikehu hou, etc.
Me ka maikaʻi o ka huahana papa mua a me nā lawelawe ʻenehana maikaʻi loa, ua lanakila mākou i ka mahalo o nā kuʻuna.I ka manawa like, i ka hoʻomohala ʻana, pili kā mākou hui i ka hui pū ʻana me nā ʻoihana kūloko a me nā ʻāina ʻē, nā keʻena noiʻi ʻepekema, nā hoʻololi ʻana o nā kulanui, i mea e hoʻomaikaʻi ai i ka R & D a me ka hiki ke hana, hana ʻia i ka hāʻawi ʻana i nā mea kūʻai aku i nā huahana a me nā lawelawe.
