| Siv NBR hauv siab -siab hydraulics | Tsis txaus extrusion kuj | O-ring extrusion puas |
| Siv FKM hauv cov nqi qis- | Tus nqi ntau dhau | Tshaj - engineering, tus nqi tsis zoo- kev ua tau zoo |
| Tsis quav ntsej txog kev tshaj tawm xov xwm | Khoom siv o | Foob tsis ua hauj lwm, ntim expansion |
- Khoom Siv Lub Npe
HNBR sib txuas peb lub peev xwm uas tsis yog NBR lossis FKM muaj ib leeg: roj tsis kam + kev laus tsis kam + extrusion tsis kam ntawm 150℃kev pabcuam txuas ntxiv. Rau cov tshuab hydraulic thiab lub cav, qhov kev sib xyaw ua ke no ua rau nws cov khoom pom zoo tshaj ob qho kev xaiv.
Khoom zoo
Khaws elasticity ntawm -40℃mus rau 150 degree.
Resistant thermal aging, tiv thaiv hardening thiab tawg.
Ua kom muaj qhov ruaj khov nyob hauv cov khoom siv roj.
Sealing Performance
Muab nruam sealing ntawm 10% -30% compression.
Retains kev sib cuag kev nyuaj siab thaum caij tsheb kauj vab.
Minimizes to los ntawm ntev - lub sij hawm compression teem.
Mechanical Adaptability
Zoo heev rebound nyob rau hauv standard grooves.
High extrusion kuj nyob rau hauv nruab nrab / siab -siab tshuab.
Tau tshaj hlau thiab tsis yog -hlau interfaces.
Teeb meem -Kev Muaj peev xwm daws tau
Tiv thaiv NBR siab -temp aging tsis ua hauj lwm.
Nres siab-kev caij tsheb kauj vab hauv hydraulics.
Tshem tawm qhov seem tsis ruaj khov los ntawm roj o.
daws qhov deformation mus tas li hauv cov ntsaws ruaj ruaj.
FAQ
Q1: Cov khoom ntim li cas?
A:Cov ntim khoom txheem muaj xws li kev lag luam- qib ib lub hnab ntim cov hnab ntim khoom, ntxiv nrog cov thawv sab nraud lossis lub hnab ntim rau kev nyab xeeb. Txhua batch tau sau meej meej nrog cov lus qhia tshwj xeeb, hom khoom siv, thiab ntau lawm batch naj npawb los xyuas kom meej tag nrho traceability.
Q2: Lub sijhawm ua haujlwm yog dab tsi?
A:Txuj hauv- qhov ntau thiab tsawg: Shipped nyob rau hauv 1-3 hnub.Custom non- qhov ntau thiab tsawg: Ntau lawm yuav siv sij hawm 5-7 hnub.(Lub sij hawm txhuas txhuas nyob ntawm qhov ntev thiab kev txiav txim kom muaj nuj nqis.)
Q3: Txoj kev thauj khoom twg tau txais kev txhawb nqa?
A:Peb muab cov kev xaiv shipping thoob ntiaj teb hauv qab no:
- DHL / FedEx Express (rau cov khoom me me)
- Air Freight (rau nruab nrab - ntim xaj)
- Hiav txwv Freight (rau loj - ntim xaj)
