Kana mumwe munhu akakumbira akanakisa gasket mugadziri mune yakasvibira tech mamiriro-angave mahydrogen masisitimu, electrolyzers, masero emafuta, kana yakakwirira-inoshanda yekupisa kupisa-pfungwa yangu yekutanga ndeyekusundira kumashure. Iko hakuna kunaka kwepasirese. Iwo musungo, zvakangofanana nekukumbira chishandiso chakanakisa pasina kutsanangura kana uri kucheka huni kana kuumba simbi. Mubvunzo chaiwo ndewekuti: ndechipi chisimbiso chinoita zvakavimbika pasi pechakanyanya, kazhinji kuranga, mamiriro achienderana nemamiriro ekunze uye kusimba kwesimba regirinhi tekinoroji? Ndiko uko iyo hurukuro inoshatisa, uye uko generic Hardware chitoro mhinduro dzinokundikana nenjodzi.

Iyo Core Dambudziko: Haisi Kungoti Nekuisa Chisimbiso

Green tech application inotsanangura kukundikana. Muinjini yechinyakare yemotokari, gasket rekuchema rinogona kureva kudonha kwemafuta kunononoka. Mune hydrogen mafuta cell stack, kutadza kudiki kwechisimbiso kunogona kutungamira kune gasi crossover, catalyst poisoning, kana yakakosha kuchengetedza chiitiko. Nhepfenyuro dzine hutsinye: mvura yakasvibiswa, haidrojeni (zvose gasi uye proton fomu), kupisa kwemhepo kubva ku cryogenic kusvika 90 ° C +, uye dzimwe nguva mild acids kana mabhesi. Chisimbiso chako chinofanira kunge chiri chemikemikari inert, iine kunamatira kwenguva refu, uye kuchengetedza elasticity pasi pekumanikidza set. Ndakaona zvikwata zvisingaite kune yakakwira-temp RTV silicone, kungoiwana ichiora mushure memaawa 500 mune yakateedzerwa PEM mafuta cell nharaunda, leaching silicone mu membrane. Ndiyo $50k stack yakaparadzwa ne $ 10 chubhu.

Kuenderana kwezvinhu ndiro gedhi rekutanga. Nezve hydrogen sevhisi, kunyanya ine esimbi zvikamu, iwe unofanirwa kudzivirira sealants izvo zvinogona kukonzera hydrogen embrittlement kana ine chlorides, sulfides. Mazhinji flange sealants kubva kuoiri & gasi nyika ari kunze. Kune ma electrolyzer anobata KOH kana deionized mvura, unoda kuramba saponification uye hydrolysis. Epoxy-based form-in-place gaskets (FIPGs) inogona kuve yakanakira kuomarara, simbi-kune-metal flanges mune kupisa kunopisa, asi iwo ari brittle. Kana paine chero kuchinjika kana kupisa kwekuwedzera kusawirirana, vanotsemuka. Iko kutengeserana.

Ipapo pane kurapa profile. Mukugadzira, haugone kugara uchitenga 24-awa yakazara kurapa pane tembiricha. Zvimwe zvivako zvinoshandisa kupisa-kukurumidza kuporesa. Asi iwe unofanirwa kuve nechokwadi chekuti tembiricha yakakwira haigadziri kubuda kunze kunosvibisa nzvimbo yegungano yakachena. Ndinoyeuka mutsetse wekunhonga solar thermal sealant apo yakasarudzwa anaerobic sealant yakarapa nekukasira papombi dzemhangura dzinodziya panguva yekusangana kwechirimo, zvichitungamira kune kusakwana kuzara uye kudonha kwaingooneka mushure mekumanikidza bhasikoro mumunda. A hope dzewaranti mari.

Chigadzirwa Landscape: Kupfuura iyo Data Sheet

Iwe uchaona mazita makuru seHenkel (Loctite), ThreeBond, Permatex. Mapepa avo ehunyanzvi ekutanga, asi iwo magwaro ekushambadzira. Kiyi ndeyekutaura kune avo mainjiniya ekushandisa uye kuwana bvunzo masampula eYAKO chaiyo kusimbiswa. Zvezvisimbiso zvakamira mumapureti ekutonhodza bhatiri, ndave nemhedzisiro yakanaka ine chaiyo Loctite silicone, iyo 5900 yakatevedzana, yakagadzirirwa kupisa kupisa. Iyo ine yakanaka kunamatira kune aluminium uye kushoma acetic acid kuburitswa panguva yekurapa (saka kushomeka kwengozi yekuora panzvimbo dzakasimba).

Kune mashandisirwo ane chekuita nehydrogen, kune niche iri kukura yefluorosilicones uye perfluorinated elastomers. Iwo anodhura, asi kupikisa kwavo kwemakemikari hakuenzaniswi. Kambani yakadai Handan Zitai Fastener Kugadzira Co, Ltd.-Kunyange ari mugadziri anomhanyisa muchikamu chikuru cheChina chikamu-anonzwisisa padyo iyi. Ivo vanoona kudiwa kweakasarudzika ekusimbisa mhinduro mumagirini tekinoroji magungano uye kudiwa kweanoenderana nzira dzekuisa chisimbiso. Kushanyira saiti yakadai zitafasteners.com, iwe unowana pfungwa yeindasitiri ecosystem; haisi kungoita bhoti, ndeyekutendeseka kwese kwakabatana, izvo zvisingadzivisiki zvinosanganisira gasket kana sealant. Kubatsira kwenzvimbo yavo padhuze nemigwagwa mikuru yekufambisa inoratidza pachiyero chekupa chinodiwa kumapurojekiti makuru egirinhi tekinoroji.

Usatarise pre-yakaumbwa gaskets zvakare. Dzimwe nguva mvura ndiyo mhinduro isiri iyo. Kune hombe, flat flanges mumafuremu eelectrolyzer, shizha rakachekwa rekuwedzera PTFE (ePTFE) seGore's kana laminated graphite sheet rinogona kukunda chero rakaiswa sealant, kunyanya kugadzirisa uye disassembly. Asi iwe unobhadhara.

The Validation Quagmire

Apa ndipo panosangana dzidziso neguyo. Iwe unoda test protocol inotevedzera chaiyo sevhisi hupenyu, inokwidziridzwa asi isiri yechokwadi. Chikanganiso chakajairika kungoita static pressure hold test pakamuri temp. Izvo hazvikuudze chero chinhu. Iwe unoda kupisa bhasikoro, kuratidzwa kwenhau, uye vibration kana zvichibvira. Isu takagadzira jig yekuyedza yakapfava yaibata makuponi akavharwa mubhavhu remvura inotenderera yakasvibiswa pa80 ° C, nevhiki nevhiki kupisa kudzika kusvika 5 ° C. Takazvimanikidza kuita bhasikoro zuva nezuva. Sealant yaitaridzika zvakanaka mushure memwedzi dzimwe nguva yaizodzikisira uye inodonha nemwedzi wechitatu. Ndiyo nguva yauri kushanda nayo.

Chimwe chakakosha, chinowanzo kanganwa, chinhu chiri pamusoro pekugadzirira. Iyo yakanakisa sealant ichakundikana pane yakasvibiswa kana isina kunaka yakashongedzwa nzvimbo. Kune simbi, chiedza chinoputika chinoputika chinoteverwa nekupusika kwe solvent (se isopropyl alcohol) ndiyo yakajairwa. Asi kune mamwe macomposites anoshandiswa mune lightweight hydrogen matangi, solvent inogona kurwisa resin. Ungangoda kurapwa kweplasma. Ndakadzidza izvi nenzira yakaoma pane kabhoni fiber composite kumanikidza mudziyo wepurojekiti. Iyo sealant bead yakangosvuuka mushure mekurapwa. Dambudziko rakanga risiri chigadzirwa; yakanga iri glossy, mold-release agent residue isu hatina kubvisa zvizere.

Mutengo vs. Kuvimbika: Iyo chaiyo Green Calculation

Mugreen tech, girinhi zvakare inoreva hupenyu hurefu uye kushoma tsvina kubva mukukundikana. A acrylic gasket maker yakachipa inogona kuchengetedza madhora makumi mashanu pachikamu chimwe chete asi ichikonzeresa kukundikana kwechikamu che5%. Mutengo wekugadzirisa, kukuvadzwa kwemhando, uye tsvina yezvishandiso (kutsiva iyo module yese) inoderedza kuchengetedza kwekutanga. Mari yako yese yekuongorora muridzi inofanira kusanganisira izvi. Dzimwe nguva, kutsanangura premium, chigadzirwa chakapupurirwa seTatuBond 1215 (yemafuta emafuta) kana yakasarudzika epoxy ndiyo yega kufamba kwemari.

Supply chain resilience zvine basa zvakare. Munguva pfupi yapfuura kushomeka kwechip, takaona zvakare kukanganisa mune yakakosha makemikari zvinhu. Kana iwe ukagadzira chigadzirwa chinotsamira pane imwechete-sosi, exotic sealant, unoisa panjodzi mutsara wako wekugadzira. Kuve nenzvimbo yechipiri inokwanisa, kunyangwe zvishoma zvishoma, zvine hungwaru. Apa ndipo panobatanidzwa nevagadziri vane nzvimbo yepasirese uye zvidyarwa zvakawanda, kana vatengesi vakakura maindasitiri vakaiswa mumahubs akaita seYongnian District, kunogona kupa kugadzikana.

Saka, Chii Mhinduro?

Izvo zvinoshungurudza zvisiri izvo, asi ndezvechokwadi: akanakisa gasket mugadziri ndiye anopfuudza yako yakaomesesa, application-chaiyo yekusimbisa bvunzo. Tanga nekutsanangura iyo midhiya chaiyo, tembiricha yemhando (min, max, uye mbiri yebhasikoro), kudzvanywa (static uye kusimba), substrate zvinhu, hupenyu hwesevhisi hunodiwa, uye zvimhingamipinyi zvegungano. Wobva waedza vaviri kana vatatu vanokwikwidza kubva kune vane mukurumbira vagadziri munzvimbo iyoyo chaiyo.

Kune gwara rakakasharara: kune general low-pressure, mvura-based masisitimu mune yakapfava temps, yemhando yepamusoro, isina kwayakarerekera-kurapa silicone inogona kukwana. Kune hydrogen uye makemikari ane hukasha, tarisa kune fluorosilicones kana fluoropolymers. Kune dzakaomarara, dzakakwirira-kudzvanywa simbi flanges, funga anaerobic kana epoxy FIPGs. Uye usambofa wakasvetuka iyo yepamusoro prep protocol.

Haisi mhinduro inonaka. Hazvina kukwana mumusoro wenyaya. Asi mumigero yegreen tech kugadzira, uko kuvimbika ndicho chinhu chete chinoita kuti tekinoroji ishande, iyi ndiyo mhinduro chete inobata mvura-kana hydrogen, kune iyo nyaya. Chinangwa hachisi chekutsvaga chigadzirwa chemashiripiti, asi kugadzira chisimbiso chekuvhara chinonyangarika, chichishanda zvakakwana uye chisingaonekwe kwehupenyu hwechigadzirwa. Ndiyo yakanyanya kunaka.
