Synthesis Of Monomer

Monomer ntawm polyimide yog Dianhydride (tetracid) thiab diamine. synthesis li ntawm diamine los ntawm ntau cov neeg tshaj mature, diamine ntau tseem yog ib lub mov hauv. Dianhydride yog ib tug hluas tshwj xeeb, ntxiv rau tua tus neeg saib xyuas rau epoxy cob mas siv rau cov synthesis of polyimide. Pyromellitic acid thiab trimellitic anhydride yuav tau muab rho tawm los ntawm peb cov roj uas muaj ntxhiab hnyav refining roj av khoom tau plaub toluene thiab toluene ib feem peb theem roj thiab theem kua oxidation nqis los. Lwm yam tseem ceeb ob anhydride, xws li phenyl 2 ketone 2 anhydride, anhydride biphenyl ob, ob phenyl ether 2 anhydride, 6 f ob anhydride thiab lwm yam los ntawm qhov hau kev synthesis, tiam sis tus nqi yuav kim heev, piv txwv rau ob fluorine anhydride ib kg kom txog qhov lab (million) rau cov. Jiande City Solver Polyimide Co., Ltd. tsim o-xylene chlorination, oxidation thiab isomerization ntawm 4 - yuav ua li cas los ntawm kev sib cais chlorinated anhydride thiab 3-chlorophthalic anhydride ntawm purity siab, nrog no ob yam tebchaw li raw cov ntaub ntawv yuav tsum synthesized series ob anhydride, cov loj tej zaum rau kim txo, khoom cua lawv tseem zoo.
