Cov txheej txheem tsim khoom thiab kev tsim khoom ntawm EPDM strips feem ntau suav nrog cov kauj ruam hauv qab no:
1. Kev npaj cov khoom siv: Npaj cov khoom siv raw khoom EPDM thiab cov khoom pabcuam raws li cov khoom yuav tsum tau ua.Qhov no suav nrog EPDM, fillers, plasticizers, stabilizers, thiab lwm yam.
2. Formula modulation: Raws li tus qauv piv ntawm cov khoom, sib tov EPDM roj hmab nrog rau lwm yam additives nyob rau hauv ib tug tej yam kev faib ua feem.Qhov no feem ntau yog ua nyob rau hauv cov roj hmab tov khoom los yog tov khoom los xyuas kom meej tias cov ntaub ntawv sib tov sib npaug.
3. Extrusion molding: Xa cov khoom sib xyaw EPDM roj hmab sib xyaw rau hauv extruder, thiab extrude qhov xav tau strip zoo los ntawm lub taub hau extrusion.Lub extruder heats, pressures thiab extrudes lub compound los ntawm ib tug extrusion tuag los tsim ib tug nruam hlaws.
4. Kev tsim thiab kho: cov roj hmab extruded strips raug txiav los yog tawg kom tau qhov ntev ntawm cov roj hmab strips.Tom qab ntawd, muab cov nplaum nplaum rau hauv qhov cub lossis lwm yam khoom siv cua sov rau kev kho kom tau txais qee qhov hardness thiab elasticity.
5. Kev kho deg: Raws li kev xav tau, qhov saum npoo ntawm cov roj hmab sawb yuav raug kho, xws li txheej txheej tshwj xeeb los yog kua nplaum, kom nws cov huab cua tsis kam, tshuaj tiv thaiv corrosion thiab adhesion.
6. Kev tshuaj xyuas thiab kev tswj xyuas zoo: Kev tshuaj xyuas thiab kev tswj xyuas zoo ntawm cov khoom tsim tawm EPDM strips, suav nrog kev tshuaj xyuas zoo li, ntsuas qhov loj me, kuaj kev ua haujlwm ntawm lub cev, thiab lwm yam, kom ua tau raws li cov khoom yuav tsum tau ua thiab cov qauv zoo.
7. Ntim thiab khaws cia: ntim cov EPDM strips uas ua tau raws li qhov yuav tsum tau ua, xws li yob lossis strips, thiab tom qab ntawd kos thiab khaws cia, npaj rau kev xa khoom lossis xa khoom mus rau lub khw.
Nws yuav tsum raug sau tseg tias cov txheej txheem tsim khoom tshwj xeeb thiab cov txheej txheem tsim khoom yuav txawv nyob ntawm cov chaw tsim khoom thiab cov khoom lag luam, tab sis cov kauj ruam saum toj no feem ntau npog cov txheej txheem ntau lawm ntawm EPDM strips.Hauv kev tsim khoom tiag tiag, nws tseem yuav tsum tau ua raws li kev tswj hwm thiab kev hloov kho raws li cov khoom xav tau thiab kev tswj hwm kev tswj hwm kom ntseeg tau tias cov khoom lag luam zoo uas ua tau raws li cov neeg siv khoom xav tau.
