Qhov kawg qhia rau cov roj hmab ntsaws pov khoom: 5 cov ntsuas yuam sij txiav txim siab cov khoom lag luam lub neej
Hauv cov cuab yeej siv khoom siv, kev lag luam Automotive, thiab lwm cov ntaub ntawv siv tshuaj, ua tsis tau zoo ntawm cov roj hmab ntsaws ruaj ruaj tuaj yeem ua rau 40% ntawm kev ua tsis tiav. Raws li kev yuav lub ntiaj teb kev txiav txim siab, koj puas ntsib kev pheej hmoo siab, kev pheej hmoo, lossis tus nqi sib kis vim lub neej tsis txaus lub neej? Kab lus no yuav muab kev ntsuas kom tob tob ntawm tsib lub neej ntawm cov kev xaiv roj hmab, thiab cov nqi kev lag luam tshwj xeeb los ntawm ntau tshaj 30%.
Cov Khoom Haum tawv: Kev kos duab ntawm ntsuas cov khoom sib txuas ua tau zoo nrog kev hnav tsis kam
Hardness (Ntug Dej Ib / IHD) muaj qhov cuam tshuam ncaj qha rau lub haum thiab durability ntawm lub foob. Cov kev tshawb fawb tau pom tias:
Tsawg Hardness (40-60 degree): Tsim nyog rau cov chaw sib txuas (xws li yooj yim hnav hauv cov xwm txheej sib txuas
Nruab nrab thiab siab tawv ({{{0}}}} degree, thiab cov extrusion tsis kam nce ntxiv los ntawm 50%
Super-hard material (>90 degree): Tshwj xeeb tsim los siv rau hauv cov tshuab siab hydraulic, tab sis nrog lubricating saum lubricating txheej kom tiv thaiv brittleness
Kev lag luam customized cov ntsiab lus:
Automotive: 60 ± 5 IRHD raug pom zoo rau qhov rooj ntsaws ruaj ruaj kom sib npaug suab thiab lub sijhawm ruaj khov
Kev Chip Ciav: Xaiv {75-85 degree corrosion-resistant fluoroelomastomer kom tawm tsam cov yaig ntawm cov kua qaub thiab alkali media
Kub Kuj Ntau Yam: Txoj cai lij choj limhiam ntawm 50% kev ua kom lub neej rau txhua 10 degree nce hauv qhov kub
Cov Khoom Siv Hluav Taws Xob Thermerynamic ntawm cov roj hmab ntsaws ruaj ruaj Qhia cov kab sib txawv tseem ceeb nonlinear txawv:
EPDM roj hmab: {-50 degree rau 150 degree rau txhua qhov xwm txheej, tab sis lub compression teeb tus nqi surges los ntawm 300% saum toj no 120 degree
Silicone roj hmab (VMQ): {{}} degree rau 230 degree ultra-dav ultra-dav ultra-dav ultra-dav ultra-dav ultra-dav ultra-dav ultra-dav ultra-dav ultra-dav ultra-dav Ultra 2011
Fluorooelastomer (FKM): tuav<20% compression set at a high temperature of 200°C, but is easy to harden and fail below -20°C Extreme
Environment Validation Data: Arctic Circle equipment: Hydrogenated nitrile rubber (HNBR) has an elastic retention rate of >85% ntawm -55 degree
Cov roj av ncu xa hluav taws xob: roj hmab fluorosneone roj hmab (FVMQ) muaj lub neej pabcuam ntau tshaj 8000 teev ntawm 180 tus lej / 5MPA
Kev teeb tsa kev teeb tsa: tus tua hluav taws xob tsis pom kev
Qhov ntsuas no cuam tshuam txog kev rov qab los ntawm cov khoom siv, uas yog qhov yuav tsum tau los ntawm cov qauv haujlwm thoob ntiaj teb tsawg dua lossis sib npaug nrog 50%. Cov kev sim tau qhia tias:
Dynamic sealing scenario: 400% increased leakage risk at 3>0% deformation tus nqi
Kev Ntsuas Siab nrawm nrawm: 72 teev ntawm 125 degree, qhov tsis txaus ntseeg ntawm cov tsis taus NBR yog 65%, thaum lub sijhawm hloov EPDM tsuas yog 28%
Txoj Kev Txhim Kho:
1. Ua ntej-COMPression Tsim: Lub compression tus nqi ntawm O-Ring Cross-Scomer Interner yog tswj hwm ntawm {4%
2. Kev muab cov hloov kho: ntxiv graphene tuaj yeem txhim kho lub resilience ntawm silicone roj hmab los ntawm 32%
Lub zog tensile: Qhov taw qhia ntau ntawm lub kua muag yeem
Lub tensile lub zog ntau dua los yog sib npaug rau 15mpa yog cov benchmark rau cov ntsaws ruaj ruaj. Cov Ntawv Thov Kom Yooj Yim Zem Tshaj Plaws:
Tsuas yog cov tshuab tsuas: loj dua los yog sib npaug rau 22mpa super roj hmab, tiv taus pob zeb nti cuam tshuam
Cov Khoom Siv Kho Mob: Platinum vulcanized silicone, elongation thaum so> 600%
Lub Cim Ceeb Toom:
When a crack of >{{0 {0}}. 5mm tshwm nyob rau saum npoo ntawm lub foob, lub tensile cov cuab yeej tau muaj kev tswj hwm 40%
Kev Tiv Thaiv Kev Nyab Xeeb: Kev ua si ntawm qhov zoo nyob rau lub sijhawm ntev
Cov roj hmab laus yog tus cwj pwm los ntawm kev hloov tawv (ΔH) thiab elongation poob (ΔE). Cov ntsaws ruaj ruaj yuav tsum ntsib:
Sab Nrauv kis rau 5 xyoo: δh tsawg dua lossis sib npaug rau 15%, ΔE tsawg dua lossis sib npaug rau 30%
Ozone concentration 50pphm Kuaj: Tsis muaj kab nrib pleb saum npoo
