Raw Khoom Xaiv thiab Kev Npaj
Kev tsim khoom pib nrog kev xaiv cov khoom siv silicone. Nyob ntawm qhov xav tau ntawm cov khoom siv, cov pos hniav silicone nrog cov kev ua tau zoo sib txawv raug xaiv. Tom qab ntawd, cov additives tsim nyog tau muab tso rau hauv qhov sib tov los kho nws cov xim, hardness, lossis lwm yam khoom siv lub cev.
Txheej txheem molding
Qhov no yog cov kauj ruam tseem ceeb uas muab cov khoom siv rau lawv cov duab tshwj xeeb. Cov txheej txheem molding muaj xws li compression molding, txhaj tshuaj molding, thiab extrusion molding. Compression molding yuav tsum tau muab ib qho hnyav ntawm cov silicone sib tov rau hauv cov pwm hlau, qhov uas nws kho tau thiab zoo li ntawm daim ntawv thov ntawm tshav kub thiab siab; Txoj kev no yog tsim rau cov khoom siv nrog cov duab zoo. Kev txhaj tshuaj molding yuav tsum tau txhaj cov silicone sib tov rau hauv pwm kab noj hniav, ua rau nws zoo tagnrho rau cov khoom siv nrog cov qauv nyuaj lossis cov uas yuav tsum tau ua kom siab - ntim ntau lawm. Extrusion molding cuam tshuam tsis tu ncua yuam cov silicone sib tov los ntawm kev tuag nrog ib tug ntoo khaub lig tshwj xeeb -sectional profile; Txoj kev no feem ntau yog siv los tsim cov ntawv txuas ntxiv xws li cov hlab thiab cov hlua.
Kev kho Vulcanization
Tom qab molding, cov khoom siv silicone tau dhau los ua cov txheej txheem vulcanization. Qhov no yog tshuaj lom neeg cov tshuaj tiv thaiv uas tau tsav los ntawm tshav kub, thaum lub sij hawm hla - kev sib txuas yog tsim los ntawm silicone molecular chains. Lub hom phiaj yog los hloov cov khoom siv los ntawm lub xeev yas mus rau hauv lub xeev elastic, yog li ua tiav cov yam ntxwv ua tau zoo kawg nkaus. Ob qhov kub thiab lub sijhawm ntawm cov txheej txheem vulcanization yuav tsum tau tswj kom meej.
Post{0}}Kev ua haujlwm
Tom qab vulcanization, cov khoom yuav xav tau trimming kom tshem tawm ntau dhau flash los yog burrs generated thaum lub sij hawm molding txheej txheem. Raws li cov kev xav tau tshwj xeeb, kev kho saum npoo- xws li tshuaj tsuag txheej lossis luam ntawv logo- kuj tuaj yeem siv tau. Tsis tas li ntawd, qee qhov precision Cheebtsam yuav raug kuaj xyuas qhov ntev.
Kev soj ntsuam zoo
Tom qab ua tiav ntawm kev tsim khoom, cov khoom tau raug kuaj xyuas los yog kuaj tag nrho. Cov txheej txheem tshuaj ntsuam xyuas muaj xws li qhov tseeb qhov tseeb, qhov pom kev pom (kuaj xyuas qhov tsis xws luag), kev ua raws li hardness, thiab kev sim ua haujlwm tsim nyog-xws li kev ntsuas kub thiab tensile zog-kom ntseeg tau tias cov khoom ua tau raws li txhua qhov kev xav tau.
