Kev piav qhia
Roj hmab O nplhaib yog ib qho khoom siv sib txuas rau qhov sib tsoo ntawm ib lub voj ntawm elastomer nrog ib puag ncig khaub lig-tsho, tsim kom tau zaum hauv lub zawj thiab nias ntawm lub sij hawm los nruab nrab ntawm ob lossis ntau qhov chaw, tsim kom muaj ib lub foob rau ntawm qhov interface.
Kev tsim
Roj Hmab O rings tuaj yeem tsim los ntawm extrusion, txhaj molded, compression molded thiab xa molded.
Qhov loj
Roj Hmo Roj Hmab muaj ntau cov roj hmab o-rings, nrog rau cov qauv AS568 thiab ISO 3601 loj:
u ID: .029 nyob rau hauv (0.74 hli) mus rau 26.0 (658.88 hli)
l CS: .040 nyob rau hauv (1.02 hli) rau .275 nyob rau hauv (6.99 hli)
Daim ntawv thov
O-rings yog ib lub cim tshaj plaws uas siv rau hauv tshuab tsim vim tias lawv zoo dua ntawm pheej yig, yooj yim ua, txhim khu kev ntseeg thiab muaj kev sib dhos yooj yim. Qhov siab lawv tuaj yeem sawv siab yog pliag psi.
Viton (FKM): Nrog rau cov tshuaj tua tsis zoo, cov roj, kub kub (-22 ° F to + 482 ° F), kev ua tau zoo ntawm cov txheej txheem tsawg zaus, cov roj tsawg permeability thiab cov yam ntxwv zoo ntawm cov laus, O rings ua hauv Viton tau loj siv nyob rau hauv cov cav ntoo, tsheb sib txuas hluav taws xob, kev ua tshuaj, thiab kev siv lub tshuab nqus tsev. Tsis muaj zog yog ketones, alkalis, thiab Skydrol ® kua.
Nitrile (NBR): Kuj hu ua Buna-N, yog siv cov khoom siv elastomer dav vim nws txoj hauj lwm tsis zoo rau lubricant thiab roj, thiab nws tus nqi pheej yig. Qhov kub ntau yog -40 ° F rau + 248 ° F. Nws yog ib qho khoom siv rau kev lag luam auto, cov kev tsav tsheb thiab cov pa roj carbon dioxide. Nws txoj kev qaug zog yog tsis kam ua rau nws ua tsis taus pa, huab cua thiab kev laus. Hydrogenated Nitrile (HNBR) tau ua kom zoo dua qub txog kev ua kom muaj cua sov, nws lub cev, thiab kev laus, thiab muab cov khoom ua kom zoo thaum nws nce siab kub mus rau + 300 ° F.
Ethylene-Propylene / EPDM: EPDM qhov kub thiab txias yog -40ºF rau + 30ºF, muaj kev tiv thaiv zoo rau cov dej sov, dej thiab chav, cov tshuaj ntxuav tais diav, cov tshuaj sodium hydroxide, roj kua roj thiab roj ntau ntau, thiab ntau cov tshuaj txhuam thiab cov tshuaj .
Silicone / VMQ: Silicone compounds yog physiologically harmless li ntawd lawv nrov nyob rau hauv cov zaub mov thiab kev kho mob. Yav zoo siab tsis kam mus rau ozone, weathering thiab kev laus, kub ntau -85ºF mus + 400ºF.
Qhia rau peb paub yog tias koj xav tau cov ntaub ntawv kom ua tau raws li cov qauv hauv qab no; UL, MIL, AMS, ASTM, FDA 21 CFR 177.2600, USP Class VI, los yog ISO 10993. Peb muaj ntau qhov tshwj xeeb uas muaj peev xwm ua tau raws li cov lus qhia uas koj tab tom nrhiav.
