O Ntiv Nplhaib Khoom Rau Kub Kub

Loj: Standard, customized ua

Khoom siv: FKM, Silicone, Fluorosilicon, HNBR, thiab lwm yam.

Muaj cov khoom sib txawv o nplhaib rau qhov kub thiab txias. Hauv qab no teev qee cov ntaub ntawv nrog nws qhov kub thiab txias.

Muaj ob lub ntsiab lus los tshaj tawm. Ua ntej yog qhov kub thiab txias yog nws qhov ntau yam. Qhov thib ob, thaum koj xaiv cov khoom siv, koj kuj yuav tsum xav txog lwm yam kev ua haujlwm xws li kev tshaj tawm thiab lub siab.

Thaum tshav kub kub tsis kam ntawm butyl roj hmab (IIR)

Feem ntau, qhov kev pabcuam kub ntawm butyl roj hmab tsis siab tshaj 150 degree. Tsuas yog cov roj hmab vulcanized butyl roj hmab tuaj yeem ua haujlwm ntev ntawm 150 degree txog 180 degree. Feem ntau chlorinated butyl roj hmab, qhov kub siab tshaj plaws rau kev siv mus sij hawm ntev yog 130 degree txog 150 degree. 160 degree rau 170 degree tsis muaj cua.

Thaum tshav kub kub tsis kam ntawm chlorosulfonated polyethylene roj hmab (CSM)

Chlorosulfonated polyethylene roj hmab tuaj yeem siv rau 1000h ntev, thiab qhov siab tshaj plaws siv yog 130 degree. Nws tuaj yeem tso cai kom nce mus rau 160 degree hauv lub sijhawm luv luv.

Thaum tshav kub kub tsis kam ntawm acrylate roj hmab

Nws qhov kub tsis kam yog siab dua li ntawm nitrile roj hmab thiab qis dua li ntawm fluororubber. Lub sijhawm ntev (1000h) kev pabcuam kub yog 170 degree Kev ua haujlwm kub tuaj yeem nce mus rau 200 degree rau lub sijhawm luv luv (70h).

Thaum tshav kub kub tsis kam ntawm fluororubber (FKM)

Feem ntau, nws qhov kub thiab txias yog 220 degree, thiab luv luv hauv 250 degree. Nws tuaj yeem txuas ntxiv tau los ntawm kev kho tshwj xeeb.

FFKM tseem muaj peev xwm ua haujlwm ntawm 316 degree, thiab tuaj yeem tuav lub zog zoo thiab elongation tom qab ntau txhiab teev ntawm 260 degree thiab ntau pua teev ntawm 288 degree

Silicone roj hmab

Tom qab cov roj hmab silicone muaj hnub nyoog ntawm 315 degree rau 24h, lub zog tsis hloov pauv.

Ntawm cov roj hmab silicone, boron-silicon roj hmab muaj qhov ua kom sov zoo tshaj plaws. Nws tuaj yeem ua haujlwm ntawm 400 degree rau lub sijhawm ntev. Nws tuaj yeem ua haujlwm tsis tu ncua rau ob peb teev ntawm 420 degree txog 480 degree.

Nitrile roj hmab (NBR)

Feem ntau, qhov kub tsis kam ntawm nitrile roj hmab tsis siab. Lub sijhawm ua haujlwm kub yog 100 degree. Txawm hais tias cov roj hmab butadiene vulcanized nrog peroxide yog siv, nws qhov kev pab cuam lub sij hawm ntev kub tsuas yog 120 degree. Nws yog qhov nyuaj kom ncav cuag 150 degree.

Hydrogenated nitrile roj hmab (HNBR)

Lub tshav kub tsis kam ntawm HNBR roj hmab tuaj yeem ncav cuag 175 degree.
