Kev tsim cov txheej txheem ntawm Polyimide Film

Kev tsim cov yeeb yaj kiab polyimide yog ob-kauj ruam txoj kev, thawj kauj ruam: Synthesis ntawm polyamide acid, theem ob: Zaj duab xis-forming imidization. Txoj kev ua yeeb yaj kiab feem ntau suav nrog txoj kev impregnation (los yog txhuas ntawv ci nplaum txoj kev), txoj kev casting thiab salivation stretching method (biaxial directional stretching method). Lub polyimide membrane uas ua los ntawm salivation txoj kev yuav siv tau nyob rau hauv ib tug me me ntawm fccl. Cov yeeb yaj kiab uas tsim los ntawm txoj kev ncab (biaxial orientation method) tau txhim kho nws cov khoom zoo, tab sis cov khoom siv ntau lawm, kev nqis peev loj thiab cov khoom lag luam siab tuaj yeem tau txais cov khoom siv yeeb yaj kiab zoo xws li kev ruaj ntseg zoo, tsis tshua muaj dej nqus thiab lwm yam.

Cov cuab yeej tseem ceeb, cov kauj ruam npaj, thiab cov khoom kuaj ntawm Polyimide Film uas ua los ntawm txoj kev salivation yog raws li hauv qab no.

Cov cuab yeej tseem ceeb

Stainless hlau resin tov cia tank, salivation nozzle, salivation tshuab, imidization rauv, winder thiab kub cua system, thiab lwm yam.

Cov kauj ruam npaj
Cov tshuaj defoamed polyamic acid (PAA) yog nias los ntawm stainless hlau tov cia tank los ntawm cov raj xa mus rau hauv lub salivation nozzle cia tank rau pem hauv ntej lub taub hau. Txoj siv hlau khiav ntawm qhov sib txawv ntawm qhov ceev ntawm cov kev taw qhia hauv daim duab, thiab cov kev daws teeb meem hauv lub tank tau muab tshem tawm los ntawm scraper nyob rau hauv pem hauv ntej ntawm cov qaub ncaug nozzle los tsim cov yeeb yaj kiab ua kua nrog cov tuab tuab, thiab tom qab ntawd nkag mus rau hauv qhov ziab kom qhuav. kom qhuav.

Cov huab cua huv thiab qhuav raug xa mus rau lub tshuab cua sov los ntawm lub tshuab cua kom preheated rau ib qho kub thiab ces nkag mus rau sab sauv thiab qis kom qhuav. Cov kev taw qhia ntws ntawm cov cua kub yog qhov sib txawv ntawm cov kev taw qhia ntawm cov hlau sawb, yog li qhov kub ntawm cov kua zaj duab xis yuav maj mam nce thaum lub sij hawm ziab, thiab cov kuab tshuaj yuav maj mam volatilize kom qhuav cov nyhuv.
Cov zaj duab xis polyamic acid khiav ntawm txoj siv hlau rau ib lub lim tiam, thiab cov kuab tshuaj evaporates los ua ib zaj duab xis, thiab cov yeeb yaj kiab tev tawm ntawm txoj siv hlau yog coj mus rau qhov cub imidization los ntawm kev qhia cov menyuam.
Lub tshuab hluav taws xob imidization feem ntau yog nyob rau hauv daim ntawv ntawm ntau cov menyuam, thiab cov ntawv qhia cov menyuam ntawm lub synchronous ceev ntawm lub tshuab casting coj cov polyamic acid zaj duab xis rau hauv lub cub tawg imidization. Tom qab qhov kub thiab txias imidization, polyimide zaj duab xis yog rewinded los ntawm lub tshuab winding los ntawm kev sib sib zog nqus txias. 269 degree mus rau qhov kub siab +400 degree, nws tseem tuaj yeem pom lub cev zoo, txhua yam thiab hluav taws xob.

Kev kuaj khoom
Tom qab cov khoom tsim, nws yuav tsum tau sim rau nws lub zog tensile, elongation ntawm so, lub zog zaus hluav taws xob lub zog, nto resistivity, ntim resistivity, thiab lwm yam.
Polyimide Zaj duab xis tsim los ntawm txoj kev salivation muaj qhov ntev ntev, yooj yim tev, zoo flatness thiab tuab tuab. Txawm li cas los xij, qhov tseeb ntawm cov khoom siv kuj yog siab; Thiab qhov viscosity ntawm PAA cov tshuaj yog qhov loj, defoaming pom yog qhov nyuaj dua, thiab cov khoom lag luam qeeb qeeb. Yog li ntawd, txoj kev salivation feem ntau yog siv rau cov yas uas tsis haum rau extrusion los yog calendering, xws li kub melting kub thiab siab yaj viscosity, los yog yas uas nws decomposition kub yog heev ze rau lub melting kub.

Ob, Salivation-ob-txoj kev Stretching Method
Nyob rau hauv cov cua kub, cov zaj duab xis yog stretched raws ib tug (uniaxial) los yog ob (biaxial) cov lus qhia nyob rau hauv lub dav hlau coordinates, thiaj li hais tias cov macromolecular chains yog stretched thiab teem raws li stretching kev taw qhia kom hloov tej yam khoom ntawm Polyimide zaj duab xis. Cov txheej txheem no hu ua PolyimideStrech orientation ntawm zaj duab xis. Feem ntau hais lus, ncab yog tsim rau kev txhim kho cov khoom ntawm cov khoom siv thermoplastic. Txoj kev ncab rau kev npaj Polyimide zaj duab xis tuaj yeem muab faib ua uniaxial stretching thiab biaxial (biaxial) stretching.

Cov khoom siv uniaxial stretching yog qhov yooj yim. Txawm li cas los xij, txawm hais tias nws ntxiv dag zog rau cov khoom siv dag zog ntawm cov khoom siv hauv cov kev taw qhia ncab, nws kuj ua rau cov khoom siv dag zog ntawm cov khoom siv nyob rau hauv txoj kab ntsug txawm phem dua li qhov tsis muaj zog. Yog li ntawd, tib neeg xav paub ntau ntxiv txog biaxial stretching. Biaxial (biaxial) ncab tuaj yeem ua rau cov saw hlau molecular taw qhia raws lub dav hlau, kom cov khoom muaj cov khoom zoo. Ob txoj kev (biaxial) tuaj yeem muab faib ua theem nrab stretching thiab thawj stretching. Lub thiaj li hu ua kev ncab theem nrab yog siv cov txheej txheem sib txawv nrog qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib npaug mus rau qhov kev taw qhia axial (longitudinal stretching), thiab tom qab ntawd siv qhov maj mam qhib lub kaum sab xis ntawm cov lus qhia kev tsheb ciav hlau kom ncav cuag qhov ntev. qee qhov nyiaj perpendicular rau axial kev taw qhia. Ntau yam (transverse stretch).

Txoj kev biaxial stretching feem ntau ntxiv ib qho kev ncab taw qhia tom qab txoj kev salivation. Cov zaj duab xis yog rhuab mus rau ib tug tshwj xeeb kub thiab stretched mus rau ib tug loj npaum li cas, thiaj li hais tias cov molecular chains yog teem kom zoo zoo raws li stretching kev taw qhia mus rau ib tug loj npaum li cas, thiab ib tug kev taw qhia yog unidirectional. Kab rov tav thiab ntsug yog ob txoj kev ncab. Tom qab ncab, lub zog yog 3-5 lub sij hawm zoo dua, qhov kub thiab txias kuj tau txhim kho, thiab lub cev muaj zog zoo dua qub. Cov kua nplaum zoo siv txoj kev no. FCCL, uas muaj cov kev xav tau siab nyob rau hauv cov nqe lus ntawm kev ua tau zoo (stabilization, thiab lwm yam), txhua tus siv Polyimide films uas tsim los ntawm txoj kev taw qhia biaxial.
