Txheej txheem cej luam
Cov kev faib tawm cov khoom siv uas nquag siv hauv O-ring specification yog tej zaum "Txheem Kev Ntsuas Cov Txheej Txheem rau Cov Khoom Roj Hmab hauv Kev Siv Tsheb." lossis ASTM D 2000. Lub kaw lus no yog tsim los pab xaiv cov khoom siv roj hmab tsim rau cov chaw ib puag ncig tshwj xeeb thiab muab "kab hu-tawm" tsim rau cov lus piav qhia ntawm elastomer cov khoom ntim.
Yuav ua li cas nyeem ASTM D 2000 Kab Hu-Tawm
Kev Hloov Kho Tshwj Xeeb
ASTM-D2000-99 M 2 HK 7 14 A1-10, B38, C12, EF31, EO88, F15, Z1
Qhov no qhia tau tias qhov kev hloov kho xyoo ntawm 02000 uas tus xov tooj hu-tawm ua rau siv.
Ntsuas Chav Nyob
ASTM D2000-99 M 2 HK 7 14 A1-10, B38, C12, EF31, EO88, F15, Z1
Yog tias ib qho M tam sim no, cov metric yuav siv rau lub zog tensile, kub, thiab tsim kua muag (MPa, ° C, thiab kN / m feem). Yog tias tsis muaj tus M no, peb yuav siv lus Askiv (psi, ° F, thiab ppi ua ke).
Qib Naj Npawb
ASTM D2000-99 M 2 HK 7 14 A1-10, B38, C12, EF31, EO88, F15, Z1
Qhia txog theem kev xeem uas yuav tsum muaj rau cov khoom siv. Piv txwv li, Qeb 1 qhia tau tias tsuas yog
yuav tsum muaj cov khoom yooj yim, thaum Qeb 2-9 xav tau cov kev sim ntsuas ntxiv xws li tsis kub thiab ua kom tsis kub tshwj xeeb. Hauv peb qhov piv txwv, peb yuav saib cov khoom fluorocarbon uas yuav tsum tau ua raws li qee yam lossis tag nrho qib 2 cov tseev kom muaj. Nco ntsoov tias Cov lej Qeb yuav tsis cuam tshuam nrog txhua yam Khoom Ntaus thiab Chav Kawm.
