Yuav Ua Li Cas Xaiv Cov Khoom Siv Roj Hmab Zoo
Tso lus
Xaiv cov khoom siv roj hmab kom haum raws li kev thov ib puag ncig yog qhov tseem ceeb, vim nws yuav tsum ua kom haum rau kev ua haujlwm xws li kub, nruab nrab, siab, thiab ib puag ncig sab nraud. Cov ntaub ntawv uas muaj zog adaptability, xws li EPDM (ethylene propylene diene monomer), NBR (nitrile butadiene roj hmab), thiab FKM (fluororubber), raug pom zoo ua qhov tseem ceeb.
Kev xaiv los ntawm qhov kub thiab txias ib puag ncig: Ua kom cov roj hmab tsis poob ntawm qhov kub thiab txias
Qhov kub tsis kam ntawm roj hmab ncaj qha cuam tshuam nws elasticity thiab lifespan. Kev xaiv cov khoom siv yuav tsum npog qhov ntsuas qhov kub thiab txias thiab tso cai rau kev nyab xeeb.
High Temperature Environment (>80 degree)
Haum rau chav kav dej, lub tshuab cua txias, thiab lwm yam.
Cov ntaub ntawv pom zoo: Fluororubber (FKM) tuaj yeem tiv taus qhov kub siab tshaj 200 degree; EPDM yog tsim rau cov dej kub thiab chav dej tsawg dua lossis sib npaug li 150 degree.
Kev Tiv Thaiv Cov Lus Qhia: Ib txwm NBR nquag ua kom tawv thiab tawg saum 120℃thiab tsis haum rau ntev -lub sij hawm siab - qhov kub thiab txias.
Tsawg- qhov kub thiab txias (<-20℃): Commonly used in outdoor equipment and cold chain transportation systems in cold regions.
Cov ntaub ntawv pom zoo: Txias- tiv taus neoprene roj hmab (CR) lossis tshwj xeeb tsim silicone roj hmab (SI), uas tuaj yeem tswj tau yooj yim hauv qab -40 degree.
Lus Cim: Cov roj hmab ntuj ua nkig ntawm qhov kub thiab txias, nws cov peev txheej muaj peev xwm txo qis, thiab muaj kev pheej hmoo ntawm tawg.
Kev xaiv los ntawm hom xov xwm: Tiv thaiv o, corrosion, lossis tshuaj lom neeg. Qhov nruab nrab conveying yog qhov tseem ceeb hauv kev txiav txim siab cov khoom siv roj hmab sab hauv. Kev xaiv cov khoom siv tsis raug tuaj yeem ua rau cov yeeb nkab nthuav dav, tawg, lossis txawm tias xau.
Roj-raws li xov xwm (roj, roj lubricating, roj hydraulic)
Cov khoom nyiam: Nitrile roj hmab (NBR): Cov ntsiab lus acrylonitrile siab dua, cov roj muaj zog dua. Dav siv nyob rau hauv automotive zog tshuab thiab industrial hydraulic khoom.
High-kawg lwm txoj: Fluororubber (FKM): Cov roj zoo heev thiab siab -kub tsis kam, haum rau siab - kev ntseeg siab xws li aerospace thiab precision machinery. Acid thiab Alkali Solutions (pH <5 lossis pH> 9)
Pom zoo: Ethylene Propylene Diene Monomer (EPDM) roj hmab: Kev tiv thaiv zoo rau cov kua qaub, muaj zog alkalis, thiab ozone, haum rau cov nroj tsuag tshuaj thiab cov dej khib nyiab.
Ib puag ncig Corrosive heev: PTFE (Polytetrafluoroethylene) cov kav dej sib xyaw tuaj yeem siv tau, tiv taus yuav luag txhua yam tshuaj corrosion.
Chav thiab Dej Kub
EPDM los yog Silicone Roj Hmab (SI) Roj Hmab yog qhov zoo dua: Cov cua sov zoo tiv thaiv thiab cov pa permeation tsis kam, feem ntau siv hauv tsev cua sov thiab cov tshuab boiler.
Cua thiab Inert Gases
General -lub hom phiaj ntuj roj hmab (NR) los yog styrene-butadiene roj hmab (SBR) tuaj yeem ua tau raws li qhov yuav tsum tau ua, muab tus nqi qis thiab kev sib khi zoo.
