Sealing thev naus laus zis yeej ib txwm ua lub luag haujlwm tseem ceeb hauv kev lag luam thiab kev tsim khoom, thiab cov chaw sib txawv thiab cov ntawv thov yuav tsum muaj cov ntawv sib txawv sib txawv. Raws li cov khoom siv sib khi, silicone O-ring yog tsim rau ntau hom kev sib khi. Linde Polymer yuav sib tham txog nws cov ntaub ntawv sib khi, qhov zoo, thiab cov ntawv thov hauv qhov tob.
Hais txog silicone rings
Silicone roj hmab yog cov khoom siv siab molecular polymer nrog cov khoom zoo xws li kub tsis kam, oxidation tsis kam, tshuaj tiv thaiv corrosion, thiab kev laus ua haujlwm. Silicone roj hmab yog ib qho tseem ceeb tshaj plaws elastic ntaub ntawv nyob rau hauv tam sim no engineering, thiab yog dav siv nyob rau hauv lub tsim ntawm industrial roj hmab cov khoom, electronics Cheebtsam, khoom siv kho mob, ntim khoom noj, thiab lwm yam. muaj pes tsawg leeg. Silicone roj hmab molecules yog peb-txoj kev covalent bond network uas muaj silicon, hydrogen, thiab oxygen. Lawv muaj qhov sib txawv ntawm qhov sib txuas siab heev thiab tsis muaj zog txaus nyiam ntawm cov molecules. Qhov no ua rau cov roj hmab silicone muaj qhov kub thiab txias tsis kam thiab tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev hauv qhov kub ntawm -60 degree rau +300 degree .
Common sealing forms
- Dynamic foob: Silicone rings tuaj yeem siv rau cov ntsaws ruaj ruaj, xws li piston ntsaws ruaj ruaj, piston pas nrig ntsaws ruaj ruaj, thiab lwm yam. Hauv kev sib khi zoo, lub nplhaib silicone tuaj yeem ua tau zoo sealing kev ua tau zoo nrog kev txav ntawm cov khoom txav thaum tuav qee qhov kev sib txhuam.
- Kev sib khi zoo li qub: Silicone rings kuj tsim nyog rau kev sib khi zoo li qub, xws li kev sib khi npog, sealing gaskets, thiab lwm yam. Nyob rau hauv lub foob zoo li qub, lub nplhaib silicone muab tso rau ntawm ob qhov chaw tiaj tus thiab ua tiav cov foob zoo los ntawm nws cov khoom elastic rov qab. Daim ntawv no yog tsim rau sealing kua, gases thiab lwm yam xov xwm.
- Threaded kev twb kev txuas sealing: Silicone O-ring yog tsim rau sealing threaded kev twb kev txuas, xws li cov yeeb nkab kev twb kev txuas, valve kev twb kev txuas, thiab lwm yam. Lub nplhaib silicone yog muab tso rau ntawm lub threaded kev twb kev txuas thiab sau cov xov sib txawv nrog nws elasticity los tiv thaiv tawm los.
- Flange sealing: Silicone rings feem ntau yog siv rau kev sib khi flange, xws li cov yeeb nkab flanges, thawv flanges, thiab lwm yam. Nws tuaj yeem sau qhov sib txawv ntawm flanges thiab xyuas kom meej sealing kev ua tau zoo ntawm kev sib koom ua ke.
Qhov zoo
- Hluav taws xob rwb thaiv tsev: Silicone yog ib qho khoom siv hluav taws xob zoo heev. Silicone rings kuj tseem siv tau los ua insulating sealing Cheebtsam hauv cov khoom siv hluav taws xob thiab hluav taws xob.
- Plasticity thiab processability: Silicone muaj cov yas zoo thiab cov txheej txheem, thiab tuaj yeem ua rau hauv silicone rings ntawm cov duab sib txawv thiab ntau thiab tsawg kom tau raws li cov kev cai sib txawv.
- Kev kub siab ua haujlwm: Silicone rings muaj qhov tshwj xeeb ntawm qhov kub thiab txias, tuaj yeem tswj tau elasticity thiab sealing kev ua tau zoo nyob rau hauv qhov kub thiab txias ib puag ncig, thiab tsim nyog rau sealing kub xov xwm.
- Corrosion tsis kam: Silicone O-ring muaj kev tiv thaiv zoo rau ntau cov tshuaj lom neeg, tsis cuam tshuam rau corrosion thiab tawg, thiab yog tsim rau sealing acid thiab alkali media.
- Kev laus ua haujlwm: Silicone rings muaj kev laus zoo heev, tuaj yeem tuav elasticity thiab sealing kev ua tau zoo rau lub sijhawm ntev, thiab tsim nyog rau kev siv mus ntev hauv kev sib khi ib puag ncig.
- Elastic rov ua tau zoo: Lub nplhaib silicone muaj kev ua haujlwm zoo elastic rov qab thiab tuaj yeem rov qab mus rau nws qhov qub zoo nyob rau hauv siab thiab tuav lub foob zoo.
Cov chaw thov
Kev sib txuas lus hauv hluav taws xob: Silicone O-rings yog siv rau kev tiv thaiv dej thiab rwb thaiv tsev hauv cov khoom siv hluav taws xob sib txuas kom ruaj ntseg ntawm cov khoom siv.
- Cov khoom siv kho mob: Silicone rings yog siv rau kev sib khi cov cuab yeej kho mob, ua raws li kev nyiam huv, thiab tuaj yeem siv tau ruaj khov hauv qhov chaw kho mob.
- Kev lag luam tsheb: Silicone rings tau dav siv rau kev sib khi lub tsheb cav, cov tshuab xa hluav taws xob thiab lwm qhov chaw kom ntseeg tau tias lub tsheb ua haujlwm li qub.
- Aerospace: Silicone rings yog tsim rau sealing cov cuab yeej aerospace thiab tuaj yeem tswj xyuas kev sib khi hauv qhov chaw huab cua.
- Kev lag luam khoom noj khoom haus: Silicone rings yog tsim rau kev sib khi hauv kev lag luam khoom noj khoom haus, ua raws li cov qauv kev noj qab haus huv, thiab yuav tsis ua paug rau zaub mov.
Silicone rings yog sealing tus neeg sawv cev nrog dav daim ntawv thov kev cia siab. Nws tuaj yeem hloov mus rau ntau hom kev sib khi. Ua ke nrog nws cov kev ua tau zoo, nws tuaj yeem ua tau zoo sealing hauv ntau qhov chaw.
