Cov gaskets siv nyob rau hauv cov kav hlau kav hlau yog qhov tseem ceeb ntawm cov khoom sib khi hauv cov kav dej sib txuas, tsim los tiv thaiv kev xau ntawm cov yeeb nkab txuas. Xaiv cov khoom siv gasket uas tsim nyog thiab ua kom muaj kev txhim kho kom zoo yog qhov tseem ceeb kom ntseeg tau tias lub sijhawm ntev -kev nyab xeeb ntawm cov kav xa dej thiab txo cov nqi xau.
Standards thiab Specifications
Rubber rings yuav tsum ua raws li GB / T 21873-2025 tus qauv, uas qhia txog qhov ntev, kam rau ua, thiab lub cev ntawm cov roj hmab nplhaib.
Hom thiab cov khoom ntawm Sealing Ring Materials
⏩ Hauv cov khoom siv dej, cov nplhaib sib khi feem ntau yog ua los ntawm SBR (styrene-butadiene roj hmab) lossis EPDM (ethylene propylene diene monomer roj hmab).
⏩ Hauv cov dej ntws, cov nplhaib sib khi feem ntau yog ua los ntawm NBR (nitrile roj hmab).
Styrene-Butadiene Roj Hmab (SBR)
Ib tug txheej txheem accessory rau ductile hlau kav thiab lub neej ntawd accessory nrog rau xa los ntawm cov yeeb nkab manufacturers.
Styrene-Butadiene Rubber (SBR) gaskets, hu ua Suav li SBR gaskets, muaj lub cev thiab txhua yam khoom, kev ua tau zoo, thiab cov khoom lag luam zoo ib yam li cov roj hmab ntuj. Txawm li cas los xij, lawv muaj kev hnav zoo dua, tiv thaiv tshav kub, thiab kev laus ua haujlwm, nrog rau cov nqi vulcanization sai dua piv rau cov roj hmab ntuj. Lawv tuaj yeem siv ua ke nrog cov roj hmab ntuj thiab ntau yam hluavtaws roj hmab. Lawv feem ntau yog siv rau hauv cov dej hauv nroog zoo tib yam kev sib txuas ua haujlwm ntawm chav tsev kub thiab tsis muaj zog corrosive.
Nitrile Roj Hmab (NBR)
Nitrile roj hmab rings, tseem hu ua nitrile roj hmab rings, yog tsim los ntawm butadiene thiab acrylonitrile los ntawm emulsion polymerization. Nitrile roj hmab feem ntau yog tsim los siv qis-kub emulsion polymerization, ua rau cov roj ua haujlwm zoo, muaj kev sib txhuam siab, ua haujlwm kub zoo, thiab muaj zog adhesion. Nws qhov tsis zoo suav nrog qhov tsis zoo - kub tsis kam, tsis zoo ozone kuj, tsis zoo rwb thaiv tsev ua haujlwm, thiab qis elasticity me ntsis. NBR rings feem ntau pom zoo rau cov kav dej thiab cov kav dej phwj tuaj.
Ethylene Propylene Diene Monomer (EPDM)
Ethylene Propylene Diene Monomer (EPDM) O-rings, paub hauv Suav li EPDM roj hmab O-rings, yog copolymer ntawm ethylene, propylene, thiab ib qho me me ntawm tsis yog{2}}conjugated diene. Raws li hom ethylene-propylene roj hmab, EPDM muaj kev tiv thaiv zoo rau ozone, tshav kub, huab cua, thiab kev laus. Nws tuaj yeem ua haujlwm hauv ib puag ncig xws li -40℃txog 120℃thiab tsim nyog rau cov ntawv thov uas yuav tsum tau ua haujlwm siab -O-rings.
T-zoo li tus tuav lub nplhaib
Lub nplhaib roj hmab sealing siv los kaw cov pob qij txha hloov tau yooj yim hauv cov kav dej hlau thiab tiv thaiv cov yeeb nkab ntawm qhov chaw ntawm qhov chaw yog feem ntau hu ua lub nplhaib tiv thaiv -slip roj hmab.
Kev sib piv ntawm T-zoo li tus tiv thaiv-slip roj hmab nplhaib thiab tus qauv T- zoo li cov roj hmab rings: Ntxiv nrog rau muaj tag nrho cov yam ntxwv ntawm kev ua tau zoo ntawm tus qauv T-zoo li tus qauv roj hmab, T-zoo li tus tiv thaiv-slip roj hmab nplhaib muaj qhov zoo dua: nws tiv thaiv lub qhov (socket) qhov chaw ntawm kev sib tw. Cov hlau txhuam hniav uas muab tso rau hauv lub nplhaib roj hmab yog ruaj khov rau lub nplhaib lub cev. Ib zaug ntsia ntawm cov yeeb nkab sib txuas, cov hniav hlau tuav cov phab ntsa ntawm cov yeeb nkab kom ruaj ntseg, kom ntseeg tau tias qhov sib koom ua ke tsis tuaj yeem yooj yim dislodged. Qhov no ua rau lawv haum rau cov kav dej uas tiv thaiv kev sib koom ua ke yog qhov yuav tsum tau ua.
