Ua npuas ncauj gasket lub luag hauj lwm hauv ntsuab tech? 

Koj paub, thaum tib neeg tham txog ntsuab tech, lawv tam sim ntawd dhia mus rau lub hnub ci vaj huam sib luag, cua turbines, los yog tej zaum hydrogen hlwb. Tsis tshua muaj leej twg nqa tau cov npuas ncauj gasket. Qhov ntawd yog thawj qhov kev xav tsis zoo. Hauv kev muaj tiag, yog tias koj tau nyob rau hauv lub Hoobkas hauv pem teb sib sau ua ke lub roj teeb ntim lossis ntim cov khoom siv hluav taws xob, koj yuav paub tias lub gasket xaiv tsis zoo tuaj yeem ua rau tag nrho lub cev ua haujlwm tau zoo. Nws tsis yog hais txog kev sib khi; Nws yog hais txog kev tswj thermal, kev co damping, thiab cov khoom siv ntev. Kuv tau pom tej yaam num uas qhov kev tsom xam engineering yog tag nrho ntawm cov ntsiab lus tseem ceeb, tsuas yog kom muaj qhov ua tsis tiav ntawm qhov chaw rov qab mus rau gasket degradation los yog outgassing uas paug qhov chaw rhiab heev. Qhov ntawd yog qhov kev sib tham tiag tiag yuav tsum pib.

Lub Overlooked Interface

Hauv cov tshuab ntsuab ntsuab-xav tias kev lag luam-teev roj teeb lub zog cia tshuab (BESS) lossis sab nraum zoov photovoltaic inverter txee-kev sib khi ib puag ncig yog qhov tseem ceeb. Tab sis nws tsis yog tsuas yog khaws cov dej tawm. Nws yog hais txog kev tswj hwm micro-ib puag ncig sab hauv. Ib lub voj kaw kaw rau cov kua ua kom txias hauv lub pob roj teeb, piv txwv li, tso siab rau cov gaskets kom tswj tau qhov siab thiab tiv thaiv cov dej xau. Yog tias cov npuas compresses teeb tsis raug, lossis cov khoom siv tsis sib haum nrog lub coolant, koj tau txais seepage. Lub coolant, feem ntau yog ib tug tshwj xeeb dielectric kua, yog kim thiab nws poob ncaj qha hits efficiency metrics. Kuv nco qab qhov kev sim uas tus neeg sib tw chav ua tsis tiav IP67 daim ntawv pov thawj tsis yog vim tsim, tab sis vim tias cov khoom siv ua npuas ncauj muaj cov qauv ntawm tes tsis sib xws, ua rau muaj kev cuam tshuam hauv cheeb tsam. Qhov kev kho tsis yog kev tsim kho dua tshiab, tab sis cov khoom siv spec hloov mus rau ib qho zoo sib xws, hla-txuas polyethylene ua npuas ncauj.

Tom qab ntawd muaj qhov thermal nam. Ntau tus xav tias hlau los yog roj hmab yog qhov mus-rau rau thermal pads. Tab sis nyob rau hauv daim ntawv thov uas yuav tsum tau ob qho tib si rwb thaiv tsev thiab sealing, zoo li lub vaj tse rau ib tug cua kub twj tso kua mis tswj chav tsev, ib tug silicone-coated urethane ua npuas ncauj gasket ua ob lub luag hauj lwm. Nws seals lub txee tiv thaiv plua plav thiab ya raws thaum muab cov thermal so kom tsis txhob muaj qhov sib txuam ntawm cov khoom siv hluav taws xob sab hauv. Qhov tseem ceeb yog txheej txheej permeability thiab ua npuas ncauj tus nqi rov qab. Yog hais tias qhov rov qab qeeb dhau tom qab compression thaum lub sij hawm sib dhos, lub foob tau so ntawm lub voj voog thermal. Peb tau kawm qhov no txoj kev nyuaj ntawm qhov project thaum ntxov, siv cov txheej txheem rebond ua npuas ncauj uas ua tau zoo hauv kev sim zoo li qub tab sis ua tsis tiav tom qab rau lub hlis ntawm txhua hnub thermal cycling. Qhov sib txawv tsim tso cai rau huab cua huab cua nkag mus, ua rau corrosion ntawm lub davhlau ya nyob twg blocks.

Kev xaiv cov khoom yog lwm qhov pitfall. "Green" yuav tsum tsis yog tsuas yog xa mus rau daim ntawv thov tab sis lub gasket nws tus kheej. Chlorinated los yog brominated nplaim taws retardants nyob rau hauv foams, feem ntau rau lub rooj sib tham UL 94 V-0 nyob rau hauv electronics, yuav muaj kev sib txawv nrog rau tag nrho-lifecycle ethos ntawm ntsuab tech yog hais tias lawv complicate recycling. Muaj kev thawb mus rau halogen-dawb, silicone-based intumescent foams. Lawv nthuav dav hauv qab cua sov kom kaw qhov khoob zoo dua, cov cuab yeej tseem ceeb rau cov tswv yim tiv thaiv hluav taws kub. Qhia cov no tsis yog ib txwm ncaj nraim; lawv cov nqi yog siab dua thiab kev ua tsis tau thaum lub sij hawm tuag-txiav yog nruj dua. Tus neeg muag khoom muaj peev xwm ntawm no yog ua-lossis-tawm.

Hauv av: Tsheb thauj mus los thiab Cov Khoom Siv Hluav Taws Xob tiag tiag

Qhov no coj kuv mus rau tej yam tswv yim: geography thiab logistics. Kev tsim cov khoom tshwj xeeb no tsis sib npaug. Rau cov ntim siab, precision-tuag-txiav ua npuas ncauj qhov chaw, koj xav tau ib tus neeg muag khoom nrog cov ntaub ntawv pov thawj zoo thiab kev tsim khoom sib xws. Kuv tau ua haujlwm nrog cov neeg koom tes hauv cov chaw lag luam loj uas lub ecosystem txhawb qhov no. Piv txwv li, HANDAN ZITAI FREWER RAUG UA MOV., Ltd., kev khiav hauj lwm los ntawm cov txheej txheem loj tshaj plaws nyob rau hauv Tuam Tshoj nyob rau hauv Yongnian, Handan, coj ib tug tseem ceeb foundations. Thaum paub txog fasteners, xws li cov hubs feem ntau muaj cov kws tshaj lij nyob ib sab hauv kev sib khi kev daws teeb meem vim qhov sib xyaw ua ke ntawm kev sib dhos. Lawv qhov chaw nyob ze cov hlab ntsha tseem ceeb xws li Beijing-Guangzhou Railway thiab National Highway 107 tsis yog ib txoj kab ntawm lub vev xaib (https://www.zitaifasteners.com); Nws txhais tau hais tias kev siv logistics efficiency. Thaum koj tab tom tswj hwm lub sijhawm sib dhos rau cua turbine nacelle cov rooj sib txoos hauv Tianjin chaw nres nkoj, muaj lub chaw xa khoom gasket uas tuaj yeem txhim kho cov khoom lag luam ntawm txoj kev thiab kev tsheb ciav hlau yam tsis muaj kev ncua yog qhov tsis sib tham ntawm qhov sib npaug ntawm kev ntseeg tau. Lub gasket zaum hauv chaw nres nkoj warehouse tsis kaw dab tsi.

Tab sis kev sib thooj tsis yog txhua yam. Kuv tau pom cov neeg muag khoom hauv cov chaw sib txuas zoo uas tseem tsis txaus ntseeg ntawm cov khoom siv traceability. Nyob rau hauv ntsuab tech, tshwj xeeb tshaj yog rau cov khoom nyob rau hauv kev sib cuag nrog coolants los yog nyob rau hauv cov huab cua txoj kev (xws li nyob rau hauv electrolyzer stacks), koj xav tau tag nrho cov ntaub ntawv ntawm polymer muaj pes tsawg leeg thiab muaj peev xwm leachables. Tus neeg xa khoom xav tau kev qhuab qhia los muab cov ntawv pov thawj tshwj xeeb. Qhov no yog qhov chaw ua haujlwm kab lis kev cai ntawm pawg tsim khoom tseem ceeb. Qhov ntom ntom ntawm cov tuam txhab tsim khoom hauv thaj chaw xws li Yongnian tuaj yeem txhawb nqa kev sib tw ntawm qhov zoo, tsis yog tus nqi xwb. Rau ib qhov project uas muaj PEM roj hlwb, peb tau txais kev cai-zoo li tus, conductive carbon-loaded ua npuas ncauj gaskets rau bipolar phaj sealing. Cov qauv thawj zaug los ntawm lub rooj cob qhia hauv zos ua tsis tau qhov kev sim ntsuas tom qab kev laus hauv cov roj simulated hloov pauv. Qhov teeb meem yog binder migration. Peb tau hloov mus rau tus txheej txheem tsim dua tshiab uas tuaj yeem tswj cov txheej txheem daim ntawv teev npe zoo dua, thiab lawv tau tshwm sim nyob rau hauv tib cheeb tsam kev lag luam dav, leveraging cov khoom siv chains muaj.

Kev tsis ua haujlwm feem ntau yog los ntawm kev sib tshuam ntawm lub gasket thiab lub fastener, lus. Ib tug npaus gasket compressed los ntawm ib tug ntsia liaj qhov rooj nyob ib ncig ntawm ib tug kev pab cuam hatch ntawm lub hnub ci tracker tsav. Yog hais tias lub fastener lub torque tsis tau teev nyob rau hauv ua ke nrog rau lub gasket lub compression kev nyuaj siab-strain nkhaus, koj yog nyob rau hauv-compression (xws li) los yog over-compress (mus tas li crush lub npuas, poob rov qab thiab foob). Qhov no yog vim li cas cov tuam txhab uas nkag siab ob qho tib si fastening thiab sealing, zoo li a fastener chaw tsim tshuaj paus diversifying rau hauv cov khoom sealing, tuaj yeem muaj kev nkag siab zoo. Lawv tau txais cov tshuab tshuab. Lub vev xaib rau Zitai Fasteners hais txog lawv txoj kev tsom mus rau cov qauv tsim khoom; qhov kev paub hauv paus yog qhov tseem ceeb. Lub gasket tsis tshua muaj kob; nws yog ib feem ntawm kev sib koom ua ke fastened.

Case hauv Point: Lub Roj Teeb Module Leak

Cia kuv piav qhia txog kev tshawb nrhiav tshwj xeeb. Ib tus neeg siv tau tshaj tawm qhov kev poob qis hauv kev ua haujlwm txias hauv lawv cov lithium-ion roj teeb modules rau cov tsheb npav hluav taws xob. Cov modules tau ua kua-txias ntawm lub phaj txias. Thermal imaging pom qhov kub tsis sib xws. Peb disassembled ib chav tsev thiab pom lub coolant channel gasket - ib tug nyias, tuab EPDM ua npuas ncauj nrog ib tug nplaum txheej - tau ib feem delaminated thiab tso cai rau ib feeb los mus. Lub coolant tau maj mam ua phem rau hauv cov npuas npuas uas nyob ib sab, degrading nws cov khoom thermal. Lub hauv paus ua rau tsis yog cov nplaum ua ntej, tab sis qhov kev npaj saum npoo ntawm aluminium txias phaj. Nws muaj ib lub zeb tiav uas yog du heev rau cov nplaum los ua ib daim ntawv cog lus ntev, ua ke nrog thermal expansion mismatch. Qhov "kho" hauv daim teb yog siv cov hlaws silicone, uas yog nkig thiab tsis ntseeg. Txoj kev daws teeb meem yog hloov mus rau lub gasket nrog cov nplaum sib txawv thiab qhia txog lub teeb abrasive pretreatment rau txhuas. Cov khoom siv gasket nws tus kheej zoo; qhov tsis ua haujlwm yog qhov teeb meem kev sib koom ua ke. Qhov no yog ib txwm-tus Ua npuas dej gasket coj lub txim, tab sis qhov teeb meem yog feem ntau nyob rau hauv tus tsim rau kev sib dhos los yog nto specs.

This experience pushed us to look more closely at closed-cell foams versus open-cell for liquid interfaces. Kaw-cell yog intuitive rau kua sealing, tab sis yog hais tias nws yog ib tug roj (xws li nyob rau hauv ib tug compressed cua zog cia lub nkoj foob), tus nqi diffusion los ntawm cov npuas matrix tseem ceeb dua. Rau hydrogen compressor, peb tau sim ntau fluorosilicon foams. Hom kev ua tsis tiav tsis yog xau rau ib tus se, tab sis hydrogen embrittlement ntawm cov npuas dej khi rau lub sijhawm, ua rau lub gasket nkig thiab nquag plua plav thaum lub sij hawm disassembly rau kev kho. Qhov kev paug paug ntawd yog ib qho teeb meem loj heev. Peb tau mus rau PTFE-raws li nthuav dav ua npuas ncauj, uas muaj cov tshuaj tiv thaiv zoo dua tab sis yog npau suav phem kom tuag-txiav kom huv tsis muaj kua muag. Tus neeg muag khoom yuav tsum tau nqis peev rau cov cuab yeej tshiab. Txhua qhov kev xaiv muaj qhov cuam tshuam ripple.

Tshaj Sealing: Acoustic thiab Vibration Damping

Lub luag haujlwm tsis sib tham yog suab nrov thiab kev co. Loj ntsuab tech installations - cua gearboxes, hydroelectric turbine halls, industrial compressors rau carbon capture - yog nrov. Ua npuas ncauj gaskets ntawm kev nkag mus rau hauv vaj huam sib luag thiab nruab nrab ntawm cov txheej txheem ua rau acoustic damping. Tab sis nws tsis yog tsuas yog hais txog kev nplawm ntawm cov npuas tuab tshaj plaws. Loj-loaded vinyl nrog ib tug npuas thaub qab yog ib txwm muaj, tab sis cov npuas qhov ntom thiab tuab yuav tsum tau kho rau lub hom phiaj zaus. Hauv qhov project rau lub tshuab hluav taws xob tidal lub tshuab hluav taws xob tswj lub txee, qhov pib tsim siv lub tshuab hluav taws xob acoustic. Nws damped high-frequency suab nrov zoo tab sis tsis ua dab tsi rau lub low-frequency hum los ntawm transformers, uas yog lub ntsiab tsis txaus siab. Peb yuav tsum ua qauv rau lub kaw lus thiab hais kom muaj ntau txheej ua npuas ncauj nrog ib qho thaiv septum. Tus nqi nce, tab sis qhov kev ua tau zoo spec tau ntsib. Qhov no yog ntsuab tech ib yam nkaus: txhim kho qhov chaw ua haujlwm thiab txo cov suab nrov.

Vibration damping yog qhov tseem ceeb rau kev ua neej ntev. Nyob rau hauv lub hnub ci taug qab cov tshuab, cov tsav tsheb thiab cov actuators yuav raug mus tas li, me ntsis txav thiab cua-induced vibration. Lub tshuab ua npuas ncauj ntawm cov ntsiab lus mounting tuaj yeem tiv thaiv fretting corrosion thiab looseness. Kuv nco qab tshuaj xyuas lub hnub ci ua liaj ua teb qhov twg ntsia liaj qhov rooj sib txuas ntawm cov kab tracker tau loosened. Tus qauv tsim muaj ib lub tiaj tiaj tiaj tiaj. Retrofitting nrog lub tshuab ntxhua khaub ncaws uas muaj EPDM ua npuas ncauj txheej ntawm ib sab daws qhov teeb meem. Ua npuas ncauj ua raws li lub caij nplooj ntoos hlav xauv lub tshuab ntxhua khaub ncaws, tswj tuav clamp load. Nws yog ib qho me me, tab sis thoob plaws ntau txhiab tus neeg taug qab, nws tiv thaiv O&M mob taub hau loj. Qhov no yog hom kev ua tau zoo, unglamorous daim ntawv thov uas ua npuas ncauj gaskets khwv tau lawv khaws cia.

Lub Sustainability Loop

Thaum kawg, cia peb tham txog qhov kawg ntawm lub neej. Cov khoom siv thev naus laus zis tiag tiag suav nrog kev tshem tawm thiab cov khoom siv rov qab. Pressure-sensitive Adhesive (PSA) ua npuas ncauj gaskets yog npau suav phem rau recyclers. Lawv kis tau txhuas los yog yas kwj. Muaj kev txaus siab rau cov thermoplastic ua npuas ncauj gaskets uas tuaj yeem ua kom sov-tev los yog sib xws nrog cov khoom siv hauv qab cov kwj deg. Piv txwv li, polyolefin ua npuas ncauj gasket ntawm polypropylene roj teeb vaj tsev yuav raug tsim los yaj thiab sib tov thaum lub sij hawm PP cov txheej txheem rov ua dua yam tsis muaj qhov tsis zoo. Qhov no yog txiav-ntug thiab tseem tsis tau tus qauv. Peb tau koom nrog kev tsav tsheb nrog EV cov chaw tsim khoom saib qhov no. Qhov kev sib tw yog nrhiav cov npuas dej uas tau ntsib cov nplaim hluav taws, kev ua haujlwm sib khi, thiab rov ua dua trifecta. Kev sib haum xeeb tam sim no yog siv cov qauv sib cais: ib qho clip-in foam strip tsis muaj nplaum. Nws ua haujlwm yog tias tus qauv tsim vaj tsev muaj qhov zawj kom zoo, tab sis ntxiv cov kauj ruam sib dhos. Nws yog kev sib pauv.

Yog li, qhov kev txiav txim yog dab tsi? Lub luag hauj lwm ntawm cov ua npuas ncauj gasket hauv ntsuab tech Nws yog ib qho tseem ceeb hais txog kev ncaj ncees thiab kev ua haujlwm ntawm cov interfaces. Nws yog ib qho kev nthuav dav uas ntsuas. Kev xaiv gasket tsis zoo tuaj yeem ua rau lub zog poob (kub, kua dej), tsis ua haujlwm ntxov ntxov, muaj kev saib xyuas ntxiv, thiab rov ua dua cov teeb meem. Cov kev coj ua zoo tshaj plaws suav nrog kev xav txog nws raws li kev tiv thaiv los ntawm qhov pib, nkag siab txog nws cov khoom siv sib cuam tshuam, thiab nrhiav los ntawm cov neeg muag khoom uas nkag siab txog cov ntsiab lus ntawm kev siv tshuab thiab ib puag ncig. Nws tsis yog cov khoom lag luam. Hauv kev thawb rau kev siv tshuab ntsuab, qee zaum lub foob me tshaj plaws yog tus tuav rov qab qhov xau loj tshaj plaws - hauv kev ua haujlwm, kev ntseeg siab, thiab thaum kawg, kev cog lus ib puag ncig nws tus kheej.
