Los ntawm cov khoom siv raw mus rau cov khoom tiav, cov nplaum nplaum tau dhau los ua cov txheej txheem molding, txhua kauj ruam shaping nws cov tsos, kev ua tau zoo, thiab kev siv tau.Cov txheej txheem molding tsis tsuas yog cuam tshuam rau kev tsim khoom, tab sis kuj ncaj qha txiav txim siab qhov flatness ntawm lub substrate, uniformity ntawm nplaum tis, thiab stability thiab kev ntseeg siab ntawm cov khoom kawg. Kev nkag siab txog cov txheej txheem no yuav pab kom nkag siab txog cov peev txheej ntawm cov kab xev zoo sib txawv thiab muab cov ntaub ntawv siv rau cov khoom siv kho kom haum rau cov ntawv thov tshwj xeeb.
Thawj kauj ruam hauv molding yog kev npaj substrate thiab pretreatment. Cov substrates sib txawv xav tau cov txheej txheem tsim khoom sib xws. Piv txwv li, polypropylene los yog polyester films feem ntau yog tsim los ntawm extrusion casting, qhov twg molten resin yog uniformly extruded rau hauv ib zaj duab xis ntawm kub kub thiab ces zoo li tus thiab mob los ntawm txias rollers. Fabric substrates undergo weaving, impregnation, thiab ziab kom muab cov fibers qhov yuav tsum tau yooj yim thiab lub zog. Daim ntawv substrates yuav tsum tswj cov fiber ntau thiab txheej txheej kom ntseeg tau tias flatness thiab printability. Ua ntej nplaum txheej, lub substrate feem ntau ua rau corona los yog plasma kho kom muaj zog saum npoo, tso cai rau kom ntub dej zoo dua thiab adhesion ntawm cov nplaum tom ntej.
Tom ntej no yog cov nplaum txheej, uas yog cov kauj ruam tseem ceeb hauv molding. Nyob ntawm cov txheej txheem nplaum thiab daim ntawv thov, txheej txheej txheej muaj xws li comma- hom kws kho hniav txheej, micro- gravure txheej, cov menyuam txheej, thiab tshuaj tsuag txheej. Comma- hom kws kho hniav txheej tso cai rau kev tswj hwm ntawm cov nplaum txheej tuab, haum rau siab - precision ob npaug - sab lossis ib sab - daim kab xev; micro- gravure txheej tswj kev sib xws thaum lub sij hawm siab - ceev ntau lawm thiab feem ntau yog siv rau bulk sealing tapes; cov menyuam txheej ua kom yooj yim rau kev sib txuas ntawm cov nplaum nplaum rau cov ntaub substrates; thiab tshuaj tsuag txheej tuaj yeem npog cov duab nyuaj lossis cov substrates tsis zoo. Thaum lub sij hawm txheej txheej txheej, kub thiab ceev yuav tsum tau sib koom ua ke los xyuas kom meej ib tug nruam, npuas -dawb nplaum txheej ntawm lub substrate thiab kom tsis txhob muaj viscosity tsis sib xws vim evaporation ceev heev.
Tom qab txheej txheej, ziab thiab kho theem pib. Feem ntau cov kuab tshuaj-raws li lossis dej-raws li cov nplaum nplaum yuav tsum tau cua sov hauv qhov cub kom tshem tawm cov kuab tshuaj los yog cov dej noo thiab ib txhij txhawb kev hloov ntawm cov nplaum txheej los ntawm cov kua hauv lub xeev mus rau ib nrab ntawm - lub xeev muaj zog nrog thawj tack. Qhov ntsuas kub ntawm qhov profile thiab airflow tus nqi yuav tsum tau teeb tsa raws li cov yam ntxwv thermal cov yam ntxwv ntawm cov nplaum nplaum kom tiv thaiv bubbling, cracking, los yog ua ntej lub sij hawm hla - txuas ntawm cov nplaum txheej. Qee qhov kub- cov nplaum nplaum yog nyob rau hauv lub xeev molten thaum lub sij hawm txheej thiab tau kho sai heev los ntawm cov cua txias, tsis tas yuav ziab ntxiv. Tom ntej no yog rewinding thiab slitting. Tom qab dhau kev soj ntsuam, qhov dav- dav dav master yob yog rewound mus rau tus qauv txoj kab uas hla ntawm lub tshuab rewinding, thiab tom qab ntawd txiav longitudinally los yog transversely kom tau cov yob tiav ntawm qhov sib txawv thiab qhov ntev. Cov kauj ruam no yuav tsum tau ua kom lub ntsej muag zoo huv si thiab tsis sib xws, tsis txhob nruj heev uas tuaj yeem ua rau substrate stretching thiab deformation, los yog overly xoob winding uas yuav ua rau interlayer slippage. Lub sharpness thiab pub ceev ntawm lub slitting hniav kuj muaj feem xyuam rau cov txiav zoo; du, burr- cov khoom tiav tiav yog yooj yim khaws thiab siv.
Thaum kawg, muaj kev tshuaj xyuas, winding, thiab ntim khoom, suav nrog kev tshuaj xyuas qhov muag, ntsuas qhov tuab, cov qauv nplaum lub zog, thiab kev ntsuas huab cua tiv thaiv, kom ntseeg tau tias txhua pawg ntawm cov khoom ua tau raws li qhov yuav tsum tau ua. Kev ntim khoom suav nrog kev tiv thaiv kev ya raws, kev tiv thaiv siab, thiab daim ntawv qhia meej kom tswj tau qhov zoo thaum khaws cia thiab kev thauj mus los.
Cov txheej txheem tsim daim kab xev muaj xws li kev npaj substrate, kev kho deg, nplaum txheej, ziab thiab kho, rov qab thiab slitting, thiab tshuaj xyuas thiab ntim. Kev tswj hwm ntawm cov tsis muaj nyob rau hauv txhua txoj kev tso cai rau kev ruaj khov ntawm cov kab xev ntawm cov khoom sib txawv thiab kev ua haujlwm, ua rau lawv ua tau raws li qhov xav tau hauv ntau qhov chaw.
