Cov ntaub ntawv rau cov ntsaws ruaj ruaj hauv pneumatic ru tsev

I. Roj Hmab Ntsaws Ruaj
1. Nitrile Roj Hmab (NBR)
Muaj feem xyuam nrog cov xwm txheej: Qhov ntsuas kub feem ntau (-20℃~ 80 DEGREE), lub teeb thauj khoom, dej tsis zoo, tus nqi qis.
Cov kev txwv: kev nquag rau kev laus ntawm cov roj kub, feem ntau cov roj tiv thaiv (tsuas yog tsim rau roj {} {{{{1} {{1} {} i}} cov roj ib puag ncig).
2. Fluororubber (FKM)
Cov txiaj ntsig: Cov roj ua tsis tau zoo tshaj plaws (o tus nqi<5%), temperature range -30℃~200℃, suitable for oil-containing media.
Qhov tsis zoo: pluag elasticity, tus nqi siab.
3. Hydrogenated Nitrile Roj Hmab (HNBR)
Nta: muaj zog corrosion resistance (acidic ib puag ncig nrog ph<5), temperature resistance -40℃~150℃.
4. Polyurethane (PU)
Kev Ua Tau Zoo: Puas Ua Haujlwm yog 3 zaug ntawm Nitrile Roj Hmab, Roj Kuj yog 5 zaug siab dua, tab sis nws yog ib qho siab dua rau kev kub siab.
Ii. Engineering Hniav
1. Polytetrafluoroethylene (PTFE)
Cov yam ntxwv: tsis tshua muaj kev sib txhuam qis dua (kwv yees li 0.04), kub tsis kam -273 degree, tab sis tus nqi siab.
2. Perfuluoroelastomer (FFKM)
Daim Ntawv Thov: Ultra - high kub (120℃~ 200 degree) ib puag ncig, compression teeb<10%.
III. Ntawv Sau Khoom
Teflon + Nitrile sib xyaw nplhaib: sib xyaw ua ke tsis tshua muaj kev sib txhuam thiab roj ua kom tsis taus, haum rau cov tshuab hydraulic thiab pneumatic.
Xaiv Kev Xaiv
Cov xwm txheej pa: ua ntej cov roj hmab nitrile lossis polyurethane.
Kev kub siab / roj teeb ib puag ncig: fluororubber lossis perfluoroelomastomer.
Acidic Media: Hydrogenated Nitrile Roj Hmab.
