Roj Hmab O-rings yog ib qho tseem ceeb hauv kev siv roj hmab foob uas tau siv ntau hauv ntau daim ntawv thov kev lag luam. Linde Polymer yuav muab cov lus qhia dav dav rau koj cov txheej txheem ntawm cov roj hmab O-ring manufacturing txheej txheem.Los ntawm kev xaiv cov khoom siv raw mus rau kev tshuaj xyuas cov khoom kawg, txhua kauj ruam tseem ceeb heev los tsim cov khoom zoo O-rings. Nyeem los ntawm tsab xov xwm no los ntawm Linde Polymer vam tias yuav muab koj lub tswv yim ntawm cov txheej txheem nyuaj koom nrog hauv kev tsim cov ntsaws ruaj ruaj ntau yam.
Kev xaiv cov khoom siv raw rau roj hmab O-rings
Thawj kauj ruam hauv kev tsim cov roj hmab O-rings yog xaiv cov khoom tsim nyog raws li kev xav tau. Kev xaiv cov khoom siv roj hmab feem ntau yog nyob ntawm cov ntawv thov tshwj xeeb, xws li qhov kub thiab txias tsis kam, tshuaj lom neeg sib raug zoo, hardness, thiab lwm yam yuav tsum tau ua. Cov khoom siv roj hmab feem ntau siv rau O-rings yog cov roj hmab nitrile (NBR), silicone roj hmab (VMQ), fluororubber (FKM), ethylene propylene diene monomer (EPDM), thiab lwm yam. Cov txheej txheem ntawm kev xaiv cov khoom siv raw muaj xws li ib puag ncig kev ua haujlwm, kua dej. compatibility, thiab kev cia siab rau kev ua tau zoo.
Kev sib xyaw ua ke
Thaum cov ntaub ntawv raw raug txheeb xyuas, cov kauj ruam tom ntej yog kev sib xyaw ua ke, cov txheej txheem uas suav nrog kev sib xyaw cov roj hmab sib xyaw nrog ntau yam khoom ntxiv xws li cov tshuaj tua kab mob, cov tshuaj tua kab mob, thiab cov tshuaj ntxiv. Cov txheej txheem sib tov feem ntau yog ua nyob rau hauv ib qho khoom siv sab hauv. Lub hom phiaj yog kom tau ib homogeneous sib tov, thiaj li hais tias cov additive yog tusyees dispersed thoob plaws hauv cov roj hmab compound. Ua tib zoo tswj lub sijhawm sib xyaw thiab qhov kub thiab txias yuav tsum tau ua kom ntseeg tau tias qhov kev ua tau zoo tshaj plaws thiab cov khoom sib xws.
Preformed
Tom qab qhov sib xyaw ua ke, nws tuaj txog rau theem preforming. Preforming yuav tsum tau ua cov roj hmab sib tov rau hauv ib qho zoo thiab siv cov pwm uas twb muaj lawm los ua kom cov O-ring zoo li xav tau. Feem ntau, qhov no yog ua los ntawm compression molding los yog kev txhaj tshuaj molding. Compression molding ua haujlwm los ntawm kev muab cov khoom sib xyaw rau hauv pwm kab noj hniav thiab siv cov cua sov thiab siab los ua kom nws zoo. Txhaj tshuaj molding, ntawm qhov tod tes, txhaj cov compound nyob rau hauv siab siab mus rau hauv lub kaw pwm. Ob txoj kev tsim cov preforms uas tuaj yeem siv rau hauv cov txheej txheem kawg.
tsim
Cov txheej txheem molding yog txheej txheem ntawm kev hloov cov roj hmab preformed rau hauv qhov kawg O-ring zoo. Nws yog ua tiav los ntawm kev sib xyaw ua ke ntawm cov cua sov thiab lub siab. Lub preform yog thawj zaug tso rau hauv pwm kab noj hniav thiab rhuab kom soften cov roj hmab. Cov pwm yog tom qab ntawd kaw thiab lub siab yog siv los xyuas kom meej tias cov roj hmab sau tag nrho cov kab noj hniav thiab tsim cov duab uas xav tau. Nyob rau lub sijhawm no, nws yog ib qho tsim nyog los tswj cov xwm txheej xws li qhov kub thiab txias, siab thiab lub sijhawm, thiab thaum kawg ua tiav cov txheej txheem kho thiab qhov tseeb.
Tom qab kho
Cov kauj ruam no yog txhawm rau txhim kho lub cev muaj zog ntawm cov roj hmab O-ring. Tom qab-kho exposes molded O-rings mus rau qhov kub thiab txias rau ib lub sij hawm tshwj xeeb ntawm lub sij hawm, ib tug txheej txheem uas yuav pab txhim kho cov khoom cua kub kuj, tshuaj tiv thaiv, thiab compression txheej. Cov txheej txheem tom qab kho yog ib kauj ruam tseem ceeb hauv kev muaj peev xwm ntawm cov khoom kom ua tau raws li qhov xav tau tshwj xeeb thiab muab lub foob zoo rau hauv daim ntawv thov zaum kawg.
Deburring thiab tshuaj xyuas
Tom qab cov txheej txheem tom qab kho tiav, O-rings yog deburred kom tshem tawm cov roj hmab ntau dhau los yog burrs uas tau tsim thaum lub sij hawm molding. Deburring tuaj yeem ua tau manually lossis siv cov khoom siv tsis siv neeg, nyob ntawm qhov ntim ntau lawm. Tom qab deburring, cov khoom raug tshuaj xyuas kom zoo rau qhov tsis xws luag lossis blemishes. Kev tshuaj xyuas suav nrog qhov tseeb qhov tseeb, qhov chaw tiav thiab tag nrho qhov zoo. Txhua yam khoom muaj teeb meem yuav raug txiav txim raws li cov khoom tsis ua raws thiab yuav tsis tawm hauv lub Hoobkas, thiab O-rings tsim nyog yuav nkag mus rau theem kawg.
Ntim thiab khaws cia
Cov kauj ruam kawg yog ntim thiab khaws cia, ua tib zoo ntim kom tsis txhob muaj kev puas tsuaj thaum thauj khoom thiab khaws cia. Feem ntau muab khaws cia rau hauv ib puag ncig tswj kom tswj tau lawv lub cev lub cev thiab txuas ntxiv lub neej txee, tsim nyog daim ntawv lo thiab cov ntaub ntawv kom paub meej cov khoom lag luam thiab kev txheeb xyuas yooj yim thaum xav tau.
