SIL silicone roj hmab O-ring:
Cov cua kub zoo heev, tiv thaiv txias, tiv thaiv ozone, thiab atmospheric aging kuj. Nws muaj cov khoom siv rwb thaiv tsev zoo heev. Txawm li cas los xij, lub zog tensile qis dua li cov roj hmab zoo tib yam thiab nws tsis tiv taus roj.
Haum rau cov khoom siv hauv tsev xws li hluav taws xob cua sov, hluav taws xob hlau, thiab microwave ncu. Nws kuj tseem tsim nyog rau ntau yam khoom uas tuaj yeem cuam tshuam rau tib neeg lub cev, xws li cov fwj dej, cov dej haus, thiab lwm yam. Tsis pom zoo siv nrog cov kuab tshuaj feem ntau, roj, concentrated acids thiab sodium hydroxide. Qhov dav dav qhov kub thiab txias yog -55 degree ~ 250 degree .
VITON fluorine roj hmab O-ring:
Nws muaj qhov kub thiab txias zoo dua li cov roj hmab silicone thiab muaj huab cua tiv thaiv zoo, ozone tsis kam thiab tshuaj lom neeg ua haujlwm, tab sis tsis zoo txias. Resistant rau feem ntau cov roj thiab cov kuab tshuaj, tshwj xeeb tshaj yog acids, aliphatic hydrocarbons, aromatic hydrocarbons, thiab tsiaj thiab zaub roj.
Sealing yuav tsum tau rau diesel xyaw, roj systems thiab tshuaj nroj tsuag. Tsis pom zoo siv cov khoom hnyav molecular hauv ketones, esters thiab cov khoom sib xyaw uas muaj nitrates. Qhov dav dav qhov kub thiab txias yog -20 degree ~ 250 degree . (Ceeb toom: roj resistant, acid thiab alkali resistant, tsis muaj)
FLS silicone roj hmab O-ring: Nws muaj qhov zoo ntawm ob qho tib si fluorine roj hmab thiab silicone roj hmab, thiab muaj cov roj zoo, hnyav tsis kam, roj tsis kam thiab siab thiab kub tsis kam. Resistant erosion los ntawm oxygenated compounds, aromatic solvents thiab chlorinated solvents.
Feem ntau siv nyob rau hauv aviation, aerospace thiab tub rog teb. Kev sib cuag nrog ketones thiab cov kua nres tsis pom zoo. Qhov dav dav qhov kub thiab txias yog -50 degree ~ 200 degree .
EPDM EPDM roj hmab O-ring:
Nws muaj huab cua tsis zoo, tiv thaiv ozone, dej tsis kam thiab tshuaj lom neeg. Nws tuaj yeem siv rau cov dej cawv thiab ketones, thiab tseem tuaj yeem siv rau sealing qhov kub thiab txias dej vapor ib puag ncig.
Haum rau cov khoom siv hauv chav dej, lub tsheb radiators, thiab lub tsheb nres tsheb. Tsis pom zoo siv nrog cov zaub mov lossis kev sib cuag nrog cov roj ntxhia. Qhov dav dav qhov kub thiab txias yog -55 degree ~ 150 degree . (Ceeb Toom: Tsis tiv taus roj, acid, thiab alkali)
