Raws li cov khoom siv roj hmab ib txwm siv, roj hmab sealing nplhaib yuav tsum muaj elasticity zoo, lub zog, siab hnav tsis kam, tensile zog thiab elongation ntawm tawg.Cov ntsuas no muaj cov kev xav tau siab thiab tuaj yeem siv los tsim cov roj hmab ntsaws ruaj ruaj uas ua haujlwm hauv qhov chaw tsis muaj roj thiab tsis muaj corrosive nruab nrab ntawm -20 ° C txog 100 ° C.Ntawm lawv, qhov hnav tsis kam cuam tshuam ncaj qha rau kev pabcuam lub neej ntawm lub nplhaib sealing thiab cov nyhuv sealing.Yog li yuav ua li cas ntxiv txhim kho qhov hnav tsis kam ntawm cov roj hmab sealing nplhaib hauv kev tsim khoom tiag?
1. Tsim nyog ua kom cov roj hmab hardness
Nyob rau hauv txoj kev xav, nce hardness ntawm cov roj hmab tuaj yeem txhim kho cov roj hmab tsis kam rau deformation.Cov roj hmab sealing nplhaib thiab qhov chaw sib cuag tuaj yeem sib npaug sib npaug ntawm kev ua haujlwm ntawm kev ntxhov siab, yog li txhim kho qhov hnav tsis kam.Feem ntau, ntau cov roj hmab sealing nplhaib manufacturers feem ntau nce cov ntsiab lus sulfur los yog ntxiv ib tug npaum li cas ntawm lub zog tus neeg sawv cev los txhim kho lub hardness ntawm cov roj hmab.
Nws yuav tsum tau muab sau tseg tias lub hardness ntawm cov roj hmab sealing nplhaib yuav tsum tsis txhob siab dhau heev lawm, txwv tsis pub nws yuav cuam tshuam lub elasticity thiab cushioning nyhuv ntawm sealing nplhaib, thiab nws thiaj li ua rau ib tug txo nyob rau hauv hnav tsis kam.
2. Kho cov roj hmab elasticity
Txhawm rau txo cov nqi ntawm cov khoom siv roj hmab, cov khoom siv roj hmab yuav ua rau cov roj hmab ntau ntau, tab sis cov roj hmab ntau dhau yuav txo cov elasticity ntawm cov roj hmab.Nws yog ib qho tsim nyog yuav tsum tswj hwm qhov ntau npaum li cas, ua kom cov roj hmab elasticity kom zoo, txo cov viscosity thiab hysteresis ntawm roj hmab, thiab txo cov coefficient ntawm kev sib txhuam los txhim kho cov hnav tsis kam ntawm cov roj hmab seals.
3. Kho qhov degree ntawm vulcanization
Raws li cov yam ntxwv ntawm cov roj hmab vulcanization kev ua tau zoo, roj hmab cov khoom lag luam tsim nyog kho cov txheej txheem vulcanization thiab vulcanization tsis ntawm cov roj hmab ntsaws ruaj ruaj kom nce qib ntawm vulcanization thiab txhim kho cov hnav tsis kam ntawm cov roj hmab seals.
4. Txhim kho lub zog tensile ntawm roj hmab
Thaum cov roj hmab siv los ua cov roj hmab sealing rings, kev siv cov khoom siv roj hmab zoo hauv cov txheej txheem tuaj yeem ua rau muaj zog intermolecular los ntawm kev txhim kho lub zog tensile thiab tensile kev nyuaj siab ntawm cov roj hmab, thiab rau qee qhov kev txhim kho cov hnav tsis kam ntawm cov roj hmab.
5. Txo qhov kev sib txhuam coefficient ntawm cov roj hmab sealing nplhaib
Ntxiv cov khoom xws li molybdenum disulfide thiab ib qho me me ntawm graphite rau cov qauv ntawm cov roj hmab sealing nplhaib tuaj yeem txo qhov kev sib txhuam coefficient ntawm cov roj hmab sealing nplhaib thiab txhim kho qhov hnav tsis kam ntawm lub nplhaib sealing.Thaum cov neeg tsim khoom siv roj hmab siv cov roj hmab los ua cov roj hmab sealing nplhaib, lawv tuaj yeem siv cov roj hmab rov qab los txo cov nqi ntawm cov khoom siv roj hmab thiab zam qhov teeb meem ntawm cov khoom siv dag zog thiab hnav tsis kam ntawm cov roj hmab los ntawm cov roj hmab ntau dhau.Tsim nyog tsim qauv ntawm cov roj hmab sealing nplhaib cov mis, kev kho kom zoo ntawm cov txheej txheem vulcanization tsis, thiab xaiv cov khoom siv zoo thiab zoo heev roj hmab tsis tuaj yeem txo tus nqi ntawm cov roj hmab sealing nplhaib raw cov ntaub ntawv, tab sis kuj txhim kho cov hnav tsis kam ntawm roj hmab sealing rings.
