Kub Kub O Rings

Loj: Standard thiab Customized

Khoom siv: Nitrile / NBR / Buna, FKM / FPM, Silicone, EPDM, HNBR, NR, FFKM, FEPM, thiab lwm yam.

Raws li koj qhov kev xav tau ua haujlwm tshwj xeeb, koj yuav tsum xaiv cov txheeb ze thiab tsim nyog kub O rings. Ntawm no yog ib qho kev qhia luv luv. Yog tias koj tsis paub meej tias cov khoom twg haum rau koj, thov hu rau peb.

Qhov kub siab tshaj plaws rau kev siv mus sij hawm ntev ntawm methyl vinyl silicone roj hmab thiab methyl phenyl vinyl silicone roj hmab yog 250 degree. Qhov kub siab tshaj plaws rau kev siv mus sij hawm ntev ntawm ethyl silicone roj hmab yuav tsum tsis pub tshaj 200 degree. Borosilicate roj hmab tuaj yeem ua haujlwm ntev ntawm 350 degree thiab tuaj yeem siv sijhawm luv luv ntawm 410 degree.

Muaj ntau ntau yam ntawm fluororubber (FKM), muaj tsawg kawg yog 12. Nyob rau hauv fluorine roj hmab, lub tshav kub tsis kam ntawm perfluoroether roj hmab ntau tshaj li lwm yam fluorine rubbers, tshwj tsis yog rau perfluorotriazine roj hmab. Nws tseem tuaj yeem ua haujlwm ntawm 316 degree, tuav lub zog zoo thiab elongation tom qab ntau txhiab teev hauv huab cua ntawm 260 degree, thiab ntau pua teev ntawm 288 degree.

Ethylene propylene roj hmab (EPDM) muaj ntau qhov kub thiab txias Qhov kev ua haujlwm yam tsawg kawg nkaus yog -40~-60 degree Nws tuaj yeem siv tau ntawm 130 degree rau lub sijhawm ntev, thiab nyob ib ncig ntawm 150 degree rau lub sijhawm luv.

Feem ntau, qhov kub tsis kam ntawm Nitrile roj hmab (NBR) tsis siab, thiab qhov kub siv mus ntev yog 100 degree; Txawm hais tias peroxide vulcanized Nitrile roj hmab siv, nws qhov kev pabcuam ntev kub tuaj yeem tsuas yog 120 degree, thiab nws nyuaj rau ncav cuag 150 degree.

Lub tshav kub tsis kam ntawm hydrogenated Nitrile roj hmab (HNBR) tuaj yeem ncav cuag 175 degree, uas yog superior rau Butyl roj hmab thiab Ethylene propylene roj hmab, thiab ntawm acrylate roj hmab thiab fluororubber.

Lub tshav kub tsis kam ntawm acrylate roj hmab (ACM) siab dua li ntawm Nitrile roj hmab thiab qis dua li ntawm fluororubber. Lub sijhawm ntev (1000h) siv kub yog 170 degree, thiab lub sijhawm luv (70h) siv kub tuaj yeem nce mus rau 200 degree.
