Ib feem ntawm Cov yam ntxwv ntawm fluorine roj hmab daim hlau
Mar 23, 2023| Compression deformation yog qhov tseem ceeb ntawm cov ntawv fluororubber siv rau kev sib khi ntawm qhov kub thiab txias. Daim ntawv thov dav ntawm Viton fluororubber yog sib cais los ntawm nws cov kev txhim kho compression deformation.
Lub zog haum ntawm fluororubber yog {{0}}Mpa; Elongation 150-300 feem pua ; Lub zog tsim kua muag nyob nruab nrab ntawm 20-40KN / m, tab sis nws elasticity tsis zoo. Kev sib txhuam coefficient ntawm fluororubber (0.8) yog me dua li ntawm nitrile roj hmab (0.9 ~ 1.5).
Qhov kub tsis kam ntawm fluororubber yog qhov dav dav, thiab qhov txwv qhov kub ntawm qhov uas nws tuaj yeem tswj tau elasticity yog {{{0}}} ~ - 20 degree . Raws li qhov kub thiab txias, nws lub zog tensile nce thiab zoo nkaus li muaj zog thiab tawv ntawm qhov kub thiab txias. Thaum ntsuas 2 hli tuab qauv qauv, nws qhov kub thiab txias yog nyob ib ncig ntawm - 30 degree ; - 45 degree rau thickness 1.87 hli; - 53 degree rau thickness ntawm 0.63mm; - 69 degree rau lub thickness ntawm 0.25 hli. Feem ntau, kev siv qhov kub thiab txias ntawm fluororubber tuaj yeem qis dua li qhov kub thiab txias. Raws li tau teev tseg hauv Teb Chaws Asmeskas tus qauv tub rog MIL-25879D, kev ua haujlwm kub yog - 40 ~ 205 degree . Qhov ntsuas kub txwv rau kev siv fluororubber hauv cov tshuab dav hlau txawv teb chaws yog - 35 degree .
Fluorine roj hmab muaj cov roj solubility zoo heev, tus nqi qis dua, thiab cov roj permeability tsawg. Hauv fluororubber, qhov sib ntxiv ntawm cov fillers ua rau cov voids hauv cov roj hmab, yog li txo cov huab cua permeability ntawm vulcanizate, uas yog qhov zoo heev rau lub tshuab nqus tsev sealing. Yog tias tsim nyog, fluororubber tuaj yeem daws qhov teeb meem ntawm 10-7Pa lub tshuab nqus tsev sealing.
