Dab tsi hloov yuav tshwm sim rau Ambient Kub Radiation ntawm Fluororubber hauv Huab Cua
Mar 17, 2023| Fluoroelastomer nyob rau hauv cov huab cua radiates ntawm chav tsev kub ntawm 5 × ntawm ib koob ntawm 107 rem, kev ua tau zoo hloov pauv ntawm 1 × Ntawm 107 roentgen, hardness nce los ntawm 1 mus rau 3 degrees, lub zog txo los ntawm tsawg dua 20 feem pua, thiab elongation txo. los ntawm 30 mus rau 50 feem pua. Yog li, nws feem ntau ntseeg tias 246 fluororubber tuaj yeem tiv taus 1 × 107 lun, fluorine roj hmab O-ring txwv yog 5 × 107 lun fluororubber muaj lub cev zoo thiab cov khoom siv kho tshuab. Lub zog ntawm hom 26 fluororubber feem ntau yog nyob nruab nrab ntawm 10 thiab 20 MPa, qhov elongation ntawm so yog nyob nruab nrab ntawm 150 thiab 350 feem pua, thiab lub kua muag tsis kam yog nyob nruab nrab ntawm 3 thiab 4 KN / m.
1. Lub zog ntawm fluororubber yog nyob nruab nrab ntawm 15.0 thiab 25MPa, qhov elongation yog nyob nruab nrab ntawm 200 feem pua thiab 600 feem pua, thiab cov kua muag tawm ntawm 2 thiab 7MPa. Feem ntau, cov txheej txheem compression ntawm fluororubber ntawm qhov kub thiab txias yog qhov loj, tab sis yog tias muab piv rau tib lub sijhawm, cov txheej txheem compression ntawm fluororubber O-ring ntawm 150 degree rau tib lub sijhawm yog loj dua rau neoprene thiab neoprene dua li 26 fluororubber, uas yog. ntawm 200 degree × Lub compression deformation ntawm 24 teev yog sib npaug rau cov roj hmab butadiene ntawm 150 degree × Compression deformation rau 24 teev.
2. Fluororubber kuj muaj cov khoom hluav taws xob zoo, thiab nws qhov nqus dej noo qis dua lwm cov elastomers. Nws tuaj yeem siv los ua cov khoom siv hluav taws xob zoo ntawm cov khoom siv hluav taws xob tsawg thiab tsis tshua muaj hluav taws xob. fluorine roj hmab muaj ib tug kuj siab solubility nyob rau hauv gases, tab sis nws diffusion tus nqi kuj me me. Yog li ntawd, tag nrho cov huab cua permeability ntawm fluorine roj hmab O-ring kuj yog me me. Lub permeability ntawm fluororubber rau oxygen, nitrogen, helium, thiab carbon dioxide gases ntawm 30 degree yog piv rau cov roj hmab butyl thiab neoprene, tab sis zoo dua li ntawm neoprene thiab ntuj roj hmab.
