Nyob zoo cov neeg siv khoom thiab cov neeg koom tes: Hauv peb cov kev sib tham txhua hnub, peb tau pom tias ntau ntawm koj txaus siab rau "kev ntsuas kub" ntawm cov khoom siv silicone ua npuas ncauj, tseem muaj lus nug. Qhov no txhais li cas tiag? Vim li cas nws tseem ceeb heev? Koj tuaj yeem xaiv qib zoo rau koj cov khoom li cas? Raws li koj tus khub ntseeg siab, peb lub hom phiaj los pab koj nkag siab tag nrho "kub cai" ntawm cov ntaub ntawv silicone ua npuas ncauj los ntawm cov lus qhia meej thiab siv tau.
Qhov ntsuas kub yog dab tsi?
Nws tsis yog ib tus lej xwb, tab sis yog "zones kev nyab xeeb". Cias muab tso, qhov ntsuas kub ntawm cov khoom siv silicone ua npuas ncauj hais txog qhov kub thiab txias uas nws tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev thiab tswj nws cov khoom tseem ceeb (xws li elasticity, sealing, rwb thaiv tsev).
Nco ntsoov ob lub ntsiab lus tseem ceeb:
Ntev -lub sijhawm ua haujlwm kub ntau:qhov kub thiab txias uas cov khoom siv tuaj yeem ua haujlwm tsis tu ncua rau 7 hnub thiab 24 teev yam tsis muaj kev puas tsuaj loj. Qhov no yog lub hauv paus tseem ceeb rau peb tsim thiab xaiv.
Luv -lub sij hawm peak kub:Cov khoom siv tuaj yeem tiv taus cua sov rau lub sijhawm luv luv (piv txwv li, ob peb teev lossis kaum feeb), tab sis nws yuav tsum tsis txhob siv los ua tus qauv ntsuas kub. Rau peb lub tuam txhab cov khoom siv silicone ua npuas ncauj, qhov ntev ntev -lub sijhawm ua haujlwm kub yog -60℃rau +200℃. Qhov no txhais tau tias nws tuaj yeem tswj tau txhua yam los ntawm qhov txias txias ntawm Arctic mus rau qhov cub zoo li cua sov.
Vim li cas qhov ntsuas kub tseem ceeb rau koj cov khoom?
Qhov ntsuas kub muaj qhov cuam tshuam loj rau kev nyab xeeb. Nyob rau hauv siab - daim ntawv thov kub (xws li sealing pads rau lub zog tshiab lub tsheb roj teeb packs thiab tshav kub rwb thaiv tsev rau cov khoom siv), yog hais tias cov khoom tsis kub resistant, nws yuav decompose, hmoov, los yog hlawv, ua rau sealing tsis ua hauj lwm, luv luv Circuit Court los yog hluav taws kub, thiab kev nyab xeeb tsis tuaj yeem lav.
Kev ntsuas kub muaj qhov cuam tshuam tseem ceeb rau kev ruaj ntseg ntawm cov khoom lag luam: xyuas kom meej tias lub foob tseem nruj nyob rau hauv kev sib hloov ntawm txias thiab cua sov, xyuas kom meej tias lub suab rwb thaiv tsev paj rwb tsis shrinkage nyob rau hauv lub kub kub ntawm lub cav compartment, thiab xyuas kom meej tias lub buffer ncoo tsis harden thiab tawg nyob rau hauv qis kub.
Kev ntsuas kub tuaj yeem pab koj txuas ntxiv lub neej ntawm cov khoom: Siv nyob rau hauv qhov ntsuas kub tuaj yeem ncua sijhawm thermal aging txheej txheem ntawm cov khoom, thiab zam kev hloov ntxov ntxov thiab kev saib xyuas cov nqi los ntawm kev ua haujlwm tsis zoo.
Silicone ua npuas ncauj VS lwm yam ntaub ntawv: Vim li cas nws yog qhov zoo tshaj plaws rau kev siv kub ntau?
Cia peb ua qhov kev sib piv intuitive:
|
khoom |
Ntev -lub sij hawm kub ntau (kwv yees.) |
Feature Analysis |
|
Cov khoom siv silicone |
-60℃~ +200 degree |
Nws muaj ntau yam ntawm qhov kub thiab txias, zoo heev yooj thiab sealing zog; roj kuj yog feem ntau |
|
EPDM ua npuas ncauj khoom |
-50℃~ +150 degree |
Zoo huab cua tsis kam, tsis kub resistant. |
|
Chloroprene ua npuas ncauj |
-40℃~ +100 degree |
Zoo nplaim taws retardant, nqaim kub ntau, yooj yim rau compress mus tas li deformation. |
|
Polyurethane ua npuas ncauj |
-30℃~ +100 degree |
Zoo elasticity, tab sis tsis tiv taus kub thiab av noo, yooj yim rau hydrolysis thiab hmoov. |
Tshaj li qhov tseem ceeb: Plaub yam cuam tshuam rau qhov ntsuas kub ntawm qhov ntsuas kub yog qhov ntsuas ntsuas, tab sis hauv kev siv tswv yim, cov hauv qab no yuav tsum tau xav txog:
Ua npuas ncauj qauv:Peb cov txheej txheem kaw ntawm tes ua npuas ncauj tuaj yeem thaiv kev hloov pauv cua sov thiab cua ncig, txhawm rau txhim kho cov rwb thaiv tsev thiab cov cua sov ua haujlwm.
Kev pab lub neej: Cov khoom siv kev ua haujlwm degradation txawv thaum ua haujlwm ntawm 200℃rau 1000 teev piv rau 5000 teev. Peb tuaj yeem muab cov kev daws teeb meem customized raws li koj qhov kev pab cuam lub neej.
Environmental nruab nrab:Cov khoom siv qhov kub thiab txias kuj yuav raug txo thaum raug cov roj cav, coolant, los yog tshuaj nyob rau hauv high kub. Thov qhia rau peb ntawm koj qhov kev ua haujlwm tshwj xeeb.
Mechanical stress:Qhov kub tsis kam ntawm silicone ua npuas ncauj nyob rau hauv lub xeev ntawm nruam compression los yog nro kuj yuav cuam tshuam me ntsis.
Phau Ntawv Qhia Tswv Yim: Yuav Ua Li Cas Xaiv Cov Khoom Zoo rau Koj Daim Ntawv Thov?
Cov khoom siv hauv tsev (lub qhov cub qhov rooj, lub qhov cub hluav taws xob): Xaiv qhov ntev - lub sij hawm ntsuas kub ntawm 200℃los tswj cov cua sov txhua hnub.
Lub zog tshiab tsheb (roj teeb gasket, lub cev muaj zog tiv thaiv npog): Cov nplaim hluav taws kub hnyiab tau +200℃kub tsis kam qib yuav tsum raug xaiv kom muaj kev nyab xeeb kiag li.
Cov cuab yeej siv hluav taws xob (pipeline rwb thaiv tsev, kev sib khi ntawm cov cuab yeej thermal): lub thermal voj voog zaus thiab nruab nrab yuav tsum tau txiav txim siab xaiv cov qauv kev ruaj ntseg zoo tshaj plaws.
Kev sib txuas lus sab nraum zoov (lub txee kaw, tsis muaj kav hlau txais xov npog): xav tau kev tiv thaiv lub caij ntuj sov lub hnub thiab lub caij ntuj no txias, qhov kub ntawm qhov dav yog qhov tseem ceeb.
Peb cov lus pom zoo: Thaum txiav txim siab koj qhov xwm txheej thov, xav txog tsis yog "kev ua haujlwm kub", tab sis kuj yog qhov siab tshaj plaws / qis kawg, qhov ntev, kev sib cuag nruab nrab, kev ntxhov siab, thiab lwm yam.
Peb pab neeg ua haujlwm yeej ib txwm npaj los muab kev pabcuam rau koj xaiv.Tiv tauj peb rau cov qauv dawb thiab cov ntaub ntawv qhia tam sim no.
