Khoom noj khoom haus ntim yob zaj duab xis yob tsis siv neeg ntim tshuab yas ntim zaj duab xis

Ib zaj yeeb yaj kiab sib xyaw ua ke uas tsim los ntawm ob lossis ntau txheej yuav tsum tsis sib cais zoo li ib zaj yeeb yaj kiab. Qhov no cuam tshuam ntau dua li tsuas yog cov nplaum ntawm ob zaj yeeb yaj kiab. Kuj tseem muaj feem cuam tshuam nrog zaj duab xis number case. Cov nplaum yog cov khoom siv hluavtaws Feem ntau cov nplaum yog ob-component polyurethane (PU) nplaum. Cov tshuaj lom neeg ntawm cov txheej txheem drilling kho cov nplaum. Cov nplaum ntawm qhov chaw ntawm lub substrate feem ntau yog cov txheej txheem lub cev thiab tsuas yog ib feem me me yog cov txheej txheem tshuaj lom neeg. Lub sijhawm no, cov khoom ntawm cov nplaum raug tho ua ke nrog cov khoom hauv zaj duab xis yas thiab kho ntxiv.
Yog tias zaj duab xis sib xyaw twb tau luam tawm thaum lub sijhawm ua cov txheej txheem sib txuas ces cov nplaum thiab cov kua mem yuav tsum ua tau raws li qhov yuav tsum tau ua ntxiv. Ib qho yuav tsum tau ua yooj yim heev yog tias txheej sab hauv yuav tsum muaj kev nplaum zoo thiab qhuav ua ntej lamination. Qhov no txhais tau tias tsis muaj cov kuab tshuaj seem hauv cov ntawv luam tawm. Tab sis cov kuab tshuaj lossis cawv feem ntau tshuav nyob hauv cov khoom sib txuas ntawm cov kua mem. Vim li no, cov khoom ntawm cov nplaum yuav tsum muaj peev xwm khi rau cov dawb radicals (-OH pawg). Txwv tsis pub, cov nplaum thiab cov neeg sawv cev kho yuav ua rau lawv tus kheej thiab poob lawv cov khoom qub.
Ntawm cov nplaum, cov nplaum uas muaj cov kuab tshuaj sib txawv ntawm cov nplaum uas tsis muaj kuab tshuaj xws li cov nplaum UV. Cov khoom sib xyaw uas muaj cov kuab tshuaj xav tau lub qhov kom qhuav kom cov kuab tshuaj ua pa. Thaum siv cov nplaum UV, lub teeb UV mus ncig los ntawm zaj duab xis sib xyaw mus rau cov nplaum kom ua cov nplaum ua ke.
1. Cov khoom qhuav
Nws yog hais txog ib txoj kev uas cov nplaum tau sib xyaw ua ke hauv lub xeev qhuav. Ua ntej, cov nplaum tau coated rau ntawm ib lub substrate. Tom qab ziab hauv qhov ziab, tag nrho cov kuab tshuaj hauv cov nplaum tau qhuav. Cov txheej txheem ntawm kev yaj cov nplaum, txuas lwm lub substrate rau nws, txias, thiab kho kom tsim cov khoom sib xyaw nrog cov khoom zoo.
2. Cov khoom sib xyaw ua ke
Nws tseem hu ua casting compounding, uas yog ib qho ntawm cov txheej txheem tseem ceeb ntawm kev tsim cov khoom ntim khoom sib xyaw ua ke. Nws yaj cov thermoplastics xws li polyethylene thiab polypropylene hauv lub tshuab extrusion compounding, thiab ntws tawm sib npaug hauv ib zaj duab xis nyias los ntawm lub taub hau tiaj tus, thiab txuas ntxiv coated rau ntawm cov khoom siv hauv paus, zaj duab xis sib xyaw ntawm ob lossis ntau txheej yog tsim los ntawm kev nias nrog lub log siab thiab txias nrog lub log txias.
Extrusion lamination muaj qhov zoo ntawm kev ceev ceev ntau lawm, cov txheej txheem yooj yim ntau lawm, ib puag ncig huv si, kev ua haujlwm siab, kev ua haujlwm yooj yim, tus nqi qis, thiab tsis muaj cov kuab tshuaj seem. Qhov chaw tseem ceeb.
