Taw qhia
Xaiv cov roj hmab gasket zoo yuav zoo li tsis tseem ceeb, tab sis nws yog ib qho tseem ceeb hauv ntau yam lag luam thiab kev siv, xws liroj hmab gasketsua lub luag haujlwm tseem ceeb ntawm kev sib khi. Tshwj xeeb tshaj yog nyob rau hauv huab cua txias, muaj zog corrosion, thiab siab siab, kev xaiv tsis raug tuaj yeem ua rau lub foob tsis ua hauj lwm, xau, downtime, thiab cov nqi tu siab. Kab lus no yuav tham txog yuav ua li cas xaiv cov roj hmab gasket zoo tshaj plaws rau kev ua haujlwm huab cua.
Kev khiav hauj lwm hnyav rau roj hmab Gaskets
Tus yuam sij rau kev xaiv cov roj hmab gasket rau ntau yam huab cua yog nkag siab txog cov teeb meem uas lub gasket yuav ntsib nyob rau hauv ntau yam kev khiav hauj lwm huab. Qhov no yuav pab txo qis cov txheej txheem xaiv thiab zam kev xaiv tsis raug. Hauv cov ntawv thov, cov kev ua haujlwm hnyav hauv qab no feem ntau ntsib:
• Qhov kub thiab txias heev
• Siab -kev sib khi ib puag ncig
• Sib cuag nrog cov kua qaub, roj, cov kuab tshuaj, thiab lwm yam tshuaj lom neeg
• Raug rau sab nraum zoov ultraviolet hluav taws xob thiab ozone
• Dynamic hnav lossis txhua yam cuam tshuam
Yam Tseem Ceeb Thaum Xaiv Roj Hmab Gaskets
Kub Resistance
Cov roj hmab feem ntau degrade ntawm qhov kub siab tshaj 150℃thiab ua nkig thiab tawg ntawm qhov kub qis. Rau cov ntawv thov uas muaj qhov kub thiab txias, Viton tuaj yeem tiv taus qhov kub txog li 250 degree, thaum silicone roj hmab tswj kev ua haujlwm zoo ntawm qhov kub thiab txias.
Tshuaj Media Compatibility
Nyob rau hauv ib puag ncig uas muaj corrosive ntau yam xws li hydraulic roj, muaj zog acids, muaj zog bases, thiab fuels, xws li cov nyob rau hauv refineries, tshuaj nroj tsuag, thiab roj systems, roj hmab tuaj yeem o thiab degrade. Cov roj hmab gasket tsim nyog yuav tsum raug xaiv rau cov tshuaj sib txawv. Nitrile roj hmab muaj kev sib raug zoo nrog ntau cov roj, thaum FKM muaj kev tiv thaiv zoo rau cov roj, cov kua qaub muaj zog, thiab cov kuab tshuaj muaj zog heev.
UV thiab Ozone Resistance
Ultraviolet lub teeb ua rau cov roj hmab molecular chains, ua rau saum npoo tawv; ozone ua rau tawg hauv cov roj hmab. Rau sab nraum zoov raug, xaiv EPDM, cov khoom siv roj hmab uas muaj UV thiab ozone tsis kam, ua kom lub gasket ntev - lub sijhawm ua haujlwm ruaj khov sab nraum zoov.
Mechanical Strength thiab Dynamic Load Performance
Thaum ua hauj lwm tej yam kev mob muaj zog vibrations, cuam tshuam, los yog dynamic reciprocating tsab ntawv tsa suab, lub gasket yuav tsum muaj siab kua muag zog thiab hnav tsis kam los tswj nws kev ncaj ncees thaum lub sij hawm tas mus li txav thiab load hloov. HNBR muaj zog hnav tsis kam thiab feem ntau ua tau zoo nyob rau hauv siab loads lossis reciprocating motion.
Siab Resistance
Lub sealing interface feem ntau withstands sab hauv lossis sab nraud. Nyob rau hauv siab - lub tshuab siab, yog tias lub gasket tsis tuaj yeem tiv taus qhov sib txawv ntawm qhov sib txawv, nws yuav raug extruded lossis tshuab tawm. FKM feem ntau muaj kev ua haujlwm siab zoo thiab cov qauv kev ruaj ntseg, ua rau nws haum rau siab - kev siv siab. Qee lub sij hawm, lub nplhaib thaub qab yog siv ua ke nrog cov roj hmab sib txuas.
Dimensions thiab Tolerances
Tau kawg, kom hloov mus rau ntau qhov chaw huab cua, peb yuav tsum siv cov khoom siv roj hmab sib txawv, tab sis kom ntseeg tau tias lub foob zoo kuj nyob ntawm qhov ntev. nruj dhau tuaj yeem ua rau kev txhim kho deformation, thaum xoob dhau yuav tsis tsim kom muaj zog clamping txaus.
Kev sib piv ntawm cov khoom siv roj hmab rau cov xwm txheej hnyav

Ua tiav Cov Txheej Txheem Qhia Txog Kev Xaiv Roj Hmab Gaskets hauv Ib puag ncig hnyav
Hauv kev ua haujlwm tsis zoo, kev xaiv kom raug ntawm cov roj hmab gaskets ncaj qha cuam tshuam rau lub neej, kev nyab xeeb, thiab kev ntseeg siab ntawm kev sib khi. Cov txheej txheem hauv qab no yuav pab koj tshawb fawb xaiv cov roj hmab gasket zoo tshaj plaws rau qhov chaw huab cua.
Txhais cov kev ua haujlwm tseem ceeb
Txhua qhov kev xaiv roj hmab gasket yuav tsum pib nrog kev nkag siab zoo ntawm cov kev ua haujlwm tiag tiag, suav nrog kev ua haujlwm tsis tu ncua, qhov kub siab tshaj plaws, lub zog siab, kev sib cuag nrog cov roj los yog kua qaub / alkaline cov kuab tshuaj, thiab seb lub foob puas zoo li qub lossis dynamic. Cov kev ua haujlwm sib txawv yuav tsum muaj cov yam ntxwv sib txawv ntawm kev ua haujlwm gasket; Yog li ntawd, cov roj hmab gasket tsim nyog yuav tsum tau xaiv raws li qhov tseem ceeb tshaj plaws ntawm kev ua haujlwm.
Xaiv cov khoom siv roj hmab sib txuam raws li kev sib cuag nruab nrab
Chemical compatibility yog ib qho tseem ceeb ntawm seb cov roj hmab gasket puas tuaj yeem ua haujlwm ntev -. Kev xaiv cov khoom siv tsis raug tuaj yeem ua rau cov roj hmab softening, o, los yog hardening, yog li sai sai poob nws lub peev xwm sealing.
Txheeb xyuas qhov kub thiab txias
Cov kub kub tuaj yeem ua kom cov roj hmab laus thiab tawv tawv, ua rau nws poob nws elasticity; Qhov kub tsis tshua muaj peev xwm ua rau cov roj hmab nkig thiab poob nws lub peev xwm los ua raws li lub sealing nto. Yog li ntawd, thaum xaiv lub gasket, nws yog ib qho tseem ceeb kom ntseeg tau tias qhov kub thiab txias ntawm cov khoom siv roj hmab nyob deb tshaj qhov kev ua haujlwm yuav tsum tau ua.
Xaiv qhov tsim nyog Hardness
Roj hmab hardness ncaj qha txiav txim siab nws compression deformation peev xwm. Tsis tshua muaj hardness tuaj yeem ua rau lub gasket raug nyem los yog deformed ntau dhau, thaum lub hardness siab dhau yuav tiv thaiv kev sib khi zoo. Qhov tseeb hardness zoo tiv thaiv to thiab extrusion puas.
Xyuas kom qhov sib piv qhov ntev, compression ratio, thiab sealing Structure
Txawm hais tias cov khoom raug xaiv kom raug, yog tias lub gasket loj lossis compression piv tsis tau raws li cov qauv kev cai, nws yuav ua rau kev sib khi tsis ua haujlwm. Nyob rau hauv siab -siab los yog dynamic tej yam kev mob, txuam thickness, tsim nyog compression piv, thiab anti{2}}extrusion tsim yog ib qho tseem ceeb heev.
Xav txog Aging Factors
Rau cov khoom siv ua haujlwm rau lub sijhawm ntev, kev laus yuav tsum tau xav txog. Kev tiv thaiv zoo heev - cov khoom laus tuaj yeem txuas ntxiv lub neej kev pabcuam ntawm lub foob, yog li txo cov khoom siv poob qis.
Ua Kev Ntsuas Kev Ntsuas Thaum Tsim Nyog
Rau cov khoom siv uas muaj kev kub siab, muaj zog corrosion, los yog muaj kev nyab xeeb, nws raug nquahu kom ua qhov kev sim ua ntej xaiv qhov kawg ntawm cov roj hmab gasket kom tsis txhob muaj kev xav tsis thoob los yog cov khoom tawg thaum lub sijhawm ua haujlwm.
Xaus
Xaiv cov roj hmab gasket uas tsim nyog nyob rau hauv kev ua haujlwm hnyav yuav tsum muaj kev nkag siab txog ntau yam khoom ntawm cov roj hmab sib txawv, suav nrog lawv qhov siab thiab qis -kub tsis kam, tshuaj lom neeg sib raug zoo, kev laus ua haujlwm, thiab lub zog txhua yam. Tsuas yog los ntawm kev xaiv cov khoom siv roj hmab uas tsim nyog thiab qhov loj me raws li kev ua haujlwm tiag tiag tuaj yeem ua tiav qhov ntev - sealing nyhuv.
Zhonggao yog lub chaw tsim khoom uas tuaj yeem muab rau koj nrog siab -cov roj hmab gaskets zoo. Thovtiv tauj pebkom tau txais kev cai roj hmab gaskets rau koj cov kev khiav hauj lwm huab.
