Polyimide hmoov Synthesis txujci

SOLVER POLYIMIDE | Updated: Oct 12, 2015

Muaj ntau ntau hom kev polyimide, kev ua lag luam rau lawm tus lag luam tsawg kawg yog 50 los sis ntau, qhov txawv uas tseem ceeb tshaj yog kev siv hluavtaws khoom los yog siv ib ntu hybrid thiab lwm cov tshuab, tuav seb yam.
Polyimide synthesis yeej siv tshuaj polycondensation txoj kev siv ib ob synthesis, cov thawj hluavtaws polyamide acid rau polyimide imide lawm. Txawm ib kauj ruam Txuag khoom raw thiab lub sij hawm, tiam sis cov kawm tag nrho cov khoom uas yuav raug txo, feem ntau yeej tsis siv.
Tam sim no nyob rau tom tsev khw polyimide cob hmoov synthesis nug lub ntsiab sib txawv rau sab imidization, muab faib ua ob pawg: tshuaj imidization, thermal imidization.
PI100-2 (ether anhydride ntaus) yog raug tshuaj imidization txoj kev, cov thawj hluavtaws polyamide kua qaub, ntxiv tseem tus neeg saib xyuas, catalysts, nag lossis daus thiab cov zoo li no. Khoom ncaj nraim ntawm hmoov ntawd, ces muab so kom qhuav.
PI00-1 (heterocyclic ntaus) yog kub imide mus ua hmoov, cov khoom cua polyamide acid thawj, ntxiv rau qhov nyiaj ntawm catalyst, precipitating kab mob los yog lub cev qhuav dej kub. Tawm hauv cov hmoov ntxhib, tom qab so qhuav, pulverization tau.
Yog vim li cas lub ntsiab polyimide hmoov puab yuav tshwm sim tom qab tej taw tes liab floc:
1. iminated tsis tag vim li cas, ib txhia tsis imidized polyamic kua qaub, qhwv hauv, zaub imidization, crosslinking sij hawm ntawm kev kub muaj peevxwm thiab lwm phenomena;
2. ib txhia ntawm qhov PI ntxhib hmoov, uas ib txhia qhov hnyav qhwv, qhov hnyav yuav ib pa sov siab, yog cov nyhuv rau PI generated lysing (qhov no yog lub tseem tos cov ntseeg).
Thaum ntshiab ua khoom khoom, tej ob yam zoo rau cov neeg kho tshuab khoom ntawm qhov khoom tsis zoo kawg thiab, tab sis muaj feem coob tus cov khoom puas, dispersing nyhuv yog qhov zoo tshaj yuav biggest. Li ntawd, tom qab tau kuaj kom tob, xws li cov ntxaij 100 los yog tshaj, uas tau rhuav tshem ntawm tej yam zoo li ob tug. Muaj ntau ntau hom kev polyimide, kev ua lag luam rau lawm tus lag luam tsawg kawg yog 50 los sis ntau, qhov txawv uas tseem ceeb tshaj yog kev siv hluavtaws khoom los yog siv ib ntu hybrid thiab lwm cov tshuab, tuav seb yam.
