Loj silicone O-rings yog dav siv nyob rau hauv ntau yam khoom siv kho tshuab thiab engineering tej yaam num. Lawv feem ntau ua haujlwm nyob rau hauv thaj chaw muaj kev lag luam, feem ntau yog siv rau kev sib khi thiab dej tsis zoo. Moulding thiab extrusion yog ob txoj haujlwm tseem ceeb uas siv los ua lawv.
Ib qho ntawm txoj kev nrov tshaj plaws rau kev tsim cov khoom loj silicone sealing rings yog cov txheej txheem molding. Siv lub zog thiab cua sov ua los ntawm lub tshuab, cov khoom siv silicone yog thawj zaug tso rau hauv cov pwm tsim tshwj xeeb thiab tom qab ntawd nias rau hauv cov duab ntawm lub foob. Cov hauv qab no yog cov haujlwm tseem ceeb hauv kev tsim khoom lag luam:
Tsim thiab tsim pwm: Ua ntej, tsim cov pwm nrog qhov ntev thiab cov ntaub ntawv raws li cov qauv thiab cov kev cai rau kev sib khi rings. Cov pwm tuaj yeem tiv taus qhov kub thiab txias thoob plaws hauv cov txheej txheem tsim khoom, vim tias nws yog tsim los ntawm cov khoom siv hlau uas tiv taus qhov kub thiab txias.
Silicone filling: Cov khoom siv silicone tau muab tso rau hauv pwm tom qab nws npaj. Tam sim no, feem ntau yog kua, cov khoom hardens thiab solidifies tom qab nws tau ntim rau hauv pwm.
Kev kho cua sov thiab kev kub siab: Txhawm rau txhawb cov khoom siv silicone kom khov, lub siab feem ntau siv rau pwm tom qab nws tau rhuab. Vim lub fact tias kev kub siab thiab kub pab nyob rau hauv cov khoom siv silicone lub peev xwm los coj cov duab ntawm lub foob thiab muab qhov tsim nyog yooj thiab durability.
Txias thiab demoulding: Lub nplhaib sealing yuav txias rau hauv pwm thiab tom qab demoulded kom rho tawm cov khoom tom qab cov txheej txheem kho tiav. Txhawm rau kom paub tseeb tias lub foob tau tsim thiab kho tau zoo, cov txheej txheem no yuav siv sijhawm qee lub sijhawm.
Lwm cov txheej txheem nrov tshaj plaws rau kev tsim cov silicone O-rings loj yog extrusion. Txhawm rau tsim kom muaj kev sib khi zoo, cov khoom siv silicone raug yuam los ntawm kev tuag siv extruder. Cov txheej txheem no cov kauj ruam yog raws li nram no:
Pretreatment ntawm cov khoom siv silicone: Txhawm rau muab cov khoom siv silicone tsim nyog viscosity thiab cov khoom, nws yuav tsum tau pretreated ua ntej extrusion. Txhawm rau kom haum rau ntau qhov ntau thiab tsawg, qhov no yuav tsum tau kho cov extruder, cua sov, thiab kev sib xyaw ua ke.
Extrusion molding: Txhawm rau tsim kom muaj lub nplhaib sib txuas txuas ntxiv, cov khoom siv silicone muab tso rau hauv extruder thiab extruded los ntawm kev tuag. Lub taub hau tuag tej zaum yuav raug kho kom tau raws li ntau lub hom phiaj, thiab feem ntau yog tsim raws li qhov tsim nyog sealing nplhaib hla ntu.
Txiav thiab txias: Lub nplhaib extruded sealing yuav raug txiav mus rau qhov ntev ntawm qhov xav tau tom qab txias thiab khov rau hauv dej lossis cua. Txhawm rau lav qhov precision thiab caliber ntawm lub foob, cov txheej txheem no tuaj yeem xav tau rau cov cuab yeej txiav tshwj xeeb lossis khoom siv.
Kev kuaj xyuas thiab ntim khoom: Txhawm rau kom paub tseeb tias cov seals tiav tiav, lawv feem ntau mus dhau qhov kev kuaj xyuas zoo. Tom ntej no, nws tau ntim rau kev khaws cia thiab kev thauj mus los yooj yim.
Rau kev sib khi rings uas yuav tsum muaj qee qhov loj lossis daim ntawv, txoj kev molding ua haujlwm zoo. Cov ntsaws ruaj ruaj yuav raug tsim raws li cov lus qhia meej vim tias cov pwm tuaj yeem hloov kho. Cov txheej txheem no tsim cov ntsaws ruaj ruaj uas feem ntau muaj tseeb thiab zoo ib yam, ua rau lawv tsim nyog rau cov ntawv thov uas yuav tsum muaj qhov loj me.
Rau kev tsim cov nruam ntev sealing rings-tshwj xeeb yog cov uas muaj qhov ntev ntev thiab cov duab yooj yim-cov extrusion mus kom ze ua haujlwm zoo. Cov txheej txheem no feem ntau yog siv rau hauv kev tsim khoom loj thiab qee qhov kev thov tshwj xeeb vim tias nws tuaj yeem ua tau sai thiab ua tau zoo tsim ntau lub nplhaib sib khi thiab tuaj yeem hloov kho raws li qhov xav tau ntawm ntau hom ntawv hla ntu.
Feem ntau, muaj ob txoj kev nrov rau kev tsim cov silicone O-rings loj: molding thiab extrusion. Txhua txoj hauv kev muaj qee qhov txiaj ntsig thiab siv cov xwm txheej. Xaiv cov txheej txheem tsim khoom uas tsim nyog rau cov txheej txheem muab yuav lav qhov tsim cov nplhaib sib khi ntawm qhov siab tshaj plaws caliber.
