Cov txheej txheem ntawm cov roj hmab self-adhesive daim kab xev feem ntau suav nrog cov kauj ruam tseem ceeb hauv qab no:
Raw khoom npaj:
Cov khoom siv roj hmab: feem ntau yog roj hmab lossis hluavtaws roj hmab, xws li roj hmab butyl, EPDM roj hmab, thiab lwm yam.
Filler: xws li carbon dub, dawb carbon dub, titanium dioxide, thiab lwm yam.
Plasticizer: xws li roj paraffin, DOP (dioctyl phthalate), thiab lwm yam.
Accelerator thiab vulcanizer: xws li sulfur, zinc oxide, stearic acid, thiab lwm yam.
Lwm yam additives: xws li antioxidants, anti-aging agents, thiab lwm yam.
Batching thiab mixing:
Ntsuas cov ntaub ntawv raw saum toj no raws li tus qauv piv.
Muab cov khoom hnyav hnyav rau hauv ib qho khoom siv sab hauv lossis ib qho qhib tov khoom rau kev sib tov kom lawv sib npaug sib npaug los tsim cov roj hmab sib xyaw.
Extrusion tshuab:
Cov roj hmab sib xyaw ua ke yog extruded rau hauv qhov yuav tsum tau strip semi-tiav khoom los ntawm extruder. Qhov kub thiab siab yuav tsum tau tswj thaum lub sij hawm extrusion txheej txheem los xyuas kom meej qhov zoo ntawm cov roj hmab siv.
Vulcanization:
Cov roj hmab extruded yog xa mus rau vulcanizer rau vulcanization. Cov txheej txheem vulcanization feem ntau yog ua tiav ntawm qhov kub thiab txias, kom cov roj hmab molecules tsim cov qauv sib txuas, yog li txhim kho nws cov khoom siv kho tshuab thiab ua haujlwm ntev.
Txhawm rau tiv thaiv tus kheej-nplaum txheej los ntawm kev ua raws thaum lub sijhawm khaws cia thiab kev thauj mus los, txheej txheej ntawm daim ntawv rov qab lossis tso tawm zaj duab xis feem ntau yog them rau ntawm tus kheej-nplaum txheej.
Slitting thiab ntim:
Cov yob loj ntawm cov roj hmab nws tus kheej-nplaum daim kab xev yog txiav rau hauv cov yob me me ntawm qhov sib txawv dav thiab ntev raws li cov neeg siv khoom xav tau.
Cov roj hmab txiav nws tus kheej-nplaum daim kab xev yog kev soj ntsuam zoo kom ntseeg tau tias cov khoom ua tau raws li qhov yuav tsum tau ua.
Thaum kawg, cov ntaub nplaum uas tsim nyog rau nws tus kheej nplaum yog ntim thiab npaj rau lub Hoobkas muag.
