Mavara-akapfachukira gaskets: inogoneka innovation? 

Kutendeseka, pandakatanga kunzwa izwi richikandwa-kandwa pashow yekutengeserana makore mashoma kumashure, kuita kwangu kwekukurumidza kwaive kukahadzika. Imwe yekushambadzira buzzword, ndakafunga. Nyika yegasket izere nezvirevo zvehupenyu hurefu uye eco-hushamwari izvo kazhinji hazvibatike pasi pekumanikidzwa chaiko, kuratidzwa kwemakemikari, kana kungoita mamiriro ekunze ekare. Munhu wese anotaura nezvazvo galvanized gaskets yekudzivirira ngura, asi kurova jira rejasi pamusoro? Izvo zvaigara zvichinzwa senge yekushongedza, nzira yekuchaja yakawanda kune chikamu chinogona kutadza nekuti machipisi ekuputira kana kukanganisa chisimbiso. Iyo yakajairika indasitiri fungidziro - imwe yandakagovera - yaive yekuti wanga uchiwana chisimbiso chinoshanda kana chakanaka. Iyo pfungwa yekuti iyo color layer pachayo inogona kubatsira mukuita uye kusimba yaiita seyakatambanudzwa.

Iyo Yakarasika Kusanzwisisa: Rura seKungopedza

Apa ndipo panotanga chiitiko chinobatika. Chikanganiso ndechekuona plating yeruvara sechinhu chisingaiti, chekushongedza. Mune yakajairwa zinc plating, iwe unowana chibayiro chekudzivirira corrosion, chokwadi. Asi ruvara, runowanzo wanikwa kuburikidza nekushandura chromate machira (blues, yero, matema, nezvimwewo), harisi rekuona zvikamu kana machina ekufananidza. Iyo yakaonda chromate layer inonyatso kusimudzira kushorwa kweiyo yepasi zinc. Icho chisimbiso chegadziro yemarara. Saka, a color-plated galvanized gasket haina galvanized + pendi. Iyo yakazara yakazara pamusoro pekurapa system. Iyo kona yekusimudzira inotangira pano: kana iyi combo ikawedzera hupenyu hwesevhisi zvakanyanya munzvimbo dzine hukasha (funga mapuratifomu ekumahombekombe ane munyu wekupfapfaidza kana makemikari emiti yemhepo), uri kuderedza kutsiva frequency, nguva yekudzikira, uye tsvina yezvinhu pamusoro pehupenyu hwese.

Asi heino-chaiyo-yepasirese kubata, iyo yaunongodzidza nekutsanangura izvi zvezvirongwa kana kubata nekutadza. Haasi ese mavara eplating akaenzana. Ukobvu uye mhando ye zinc layer ndeye hwaro. Ndakaona ma gaskets apo ruvara rwakanga rwuine simba asi iyo zinc substrate yaive yakatetepa, zvichitungamira kumarara tsvuku kubuda mushure memwaka. Iyo yekutadza nzvimbo yanga isiri iyo gasket zvinhu pachayo, asi iyo yakakanganiswa corrosion barriers. Chipikirwa chakasimba chinodonha kana chigadzirwa chikasaunza pane chayo chekusimba chekudaidzira. Zvinokumanikidza kuti utarise kupfuura iyo spec sheet uye kubvunza nezve process control. Mutengesi akafanana Handan Zitai Fastener Kugadzira Co, Ltd., yakavakirwa muChina's hombe fastener hub muYongnian, Hebei, kazhinji ine mukana weiyo yakabatanidzwa kugadzirwa. Kudzora matanho ekuputira uye ekuputira mukati-mumba, pane kuburitsa kunze, zvinogona kureva kuenderana kuri nani - chinhu chakakosha asi chinowanzo furatirwa mukuita chaiko kwehupenyu.

Ipapo pane chemistry yechromate pachayo. Indasitiri iri kufamba, kunyangwe zvishoma nezvishoma, kure nehexavalent chromium (yemhando yepamusoro, inoshanda zvakanyanya asi ine muchetura uye yakadzorwa goridhe iridescent kupera) yakananga kune trivalent chromates. Aya maitiro matsva emavara haana ngozi shoma. Kana mugadziri akadyara mumitsetse ine chromate mitsara, iro inhanho inobatika yakananga kune yakagadzikana yekugadzira maitiro, kuderedza nharaunda uye yevashandi njodzi dzehutano. Saka, hutsva hausi nguva dzose mune chigadzirwa chaunobata muruoko rwako, asi mumagadzirirwo kumashure pafekitari pasi. Paunenge uchiongorora, zvakakodzera kubvunza kuti ndeupi rudzi rwechromate inoshandiswa. Mhinduro inokuudza zvakawanda nezve izvo zvinokosheswa nekambani nhema.

Nyaya Iripo: The Valve Bank Retrofit

Rega ndikupe muenzaniso wekongiri kubva kune yekuchenesa mvura chirimwa retrofit yatakabvunza pane imwe nguva kumashure. Vaive nenyaya dzinodzokororwa neyakajairwa zinc-plated gaskets pane ekunze mavharuvhu manifolds. Corrosion yaikonzera kubatwa nekudonha, zvichikonzera kurasikirwa nemvura uye kutemwa nemusoro mwedzi 18 yega yega. Takaronga kutongwa nebatch ye color-plated galvanized gaskets uchishandisa yebhuruu trivalent chromate kupera. Ruvara rwacho rwakakumbirwa neboka rekuchengetedza kuti rizivikanwe zviri nyore kutarisana nezvikamu zvekare zvesirivha zinc.

Makore matatu zvichienda mberi, iwo manifolds achiri musevhisi pasina kana imwe kutadza kunoenderana negasket. Mutengo wacho waive pamwe 15-20% yakakwira payuniti pakutanga. Asi kana iwe uchitarisa mumutengo wevashandi wechikwata chevanhu vaviri vanopedza zuva kutsiva bhanga remagasi, pamwe nemutengo wekugadzira kuderera kana kurasikirwa kwemvura, hupfumi hunochinja zvakanyanya. Iko kuhwina kwekusimudzira kwaive kwakapetwa kaviri: kuderedzwa kukuru kwekushandisa kwasara uye kwakabatana kugadzira / chekufambisa tsoka, uye kudzivirira kwekubuda kunosvibisa kubva kune zvisimbiso zvakakundikana. Urwu ndirwo rudzi rwekuenderera mberi kunokosha - kushanda zvakanaka uye kuderedzwa kwemarara kunotungamirwa nechikamu chakasimba.

Chidzidzo chakanga chisiri icho chine ruvara-chakapfava ndiyo nguva dzose mhinduro. Kune yakakwirira-tembiricha kana yakanyanyisa makemikari basa, iwe unenge uchiri kutarisa kune isina tsvina kana PTFE. Asi kune yakakura yakawanda yekushandiswa kwemaindasitiri mune ine corrosive renji, musanganiswa uyu unobaya pamusoro pehuremu hwawo. Yakashandura maonero angu kubva pakuiona segimmick kusvika pakuiona sechombo chiri pamutemo chekuwedzera nguva dzekugadzirisa.

The Manufacturing and Supply Chain Reality

Kunyura zvakadzika, mubvunzo wekusimudzira hausi wechigadzirwa chiri kushandiswa chete. Zviri pamusoro pekuti inogadzirwa sei uye inofambiswa sei. Apa ndipo panopinda geography uye logistics. Kambani iri munzvimbo yakabatikana yekugadzira, senge Handan Zitai iri muYongnian nekuwana kwayo yakananga njanji huru uye nzira dzekubatanidza (iyo Beijing-Guangzhou Railway uye National Highway 107 dziri ipapo), ine yakavanzika mukana. Efficient logistics zvinoreva kuderera kwekabhoni emissions pane imwe neimwe yekutakura kana mbishi ichipinda uye zvinhu zvapera zvichibuda. Kune mutengi wepasi rose, kubatanidza odha ye galvanized gaskets uye zvimwe zvigadziriso kubva kune imwechete, yakanyatsobatanidzwa sosi inogona kuderedza iyo yese yezvakatipoteredza mutengo wekutenga. Iyo systemic chinhu chisingawanzo kutaurwa mumabhurocha echigadzirwa asi yakakosha muhuwandu hwekuverenga tsoka.

Pasi pefekitari, kukanganisa kwezvakatipoteredza kunotsamira pakurapwa kwemarara. Zinc plating uye chromating inoburitsa tsvina. Vagadziri vanotungamira mumatunhu akaita seYongnian vava pasi pemitemo yakasimba yezvakatipoteredza, vachimanikidza kudyara mune yakavharwa-loop kana epamberi kurapwa masisitimu. Kana iwe uchibva kune ane mukurumbira mugadziri, iwe unotsigira zvisina kunanga kugadzirwa kwakarongeka, kwakachena. Icho chimiro chekuchengetedza cheni. Iyo imwe nzira - kutenga iyo yakachipa sarudzo kubva kuchitoro chisina kunyoreswa - inogona kuchengetedza masendi pachidimbu asi inoburitsa kunze mutengo wezvakatipoteredza nenzira yakaoma. Iyi inyanzvi yekutonga yekufona yatinofanira kuita nguva dzose: mutengo wakaderera maringe nemutengo wakaderera chaiwo.

Iko Innovation Ichiri Kudonha Pfupi

Ngatirege kutakurwa, zvakadaro. Kuzvidaidza kuti hunyanzvi hwakasimba hunoda humwe hunhu hunorema. Iyo nzira ichiri simba-yakawanda (kudziya plating mabhati) uye inoshandisa makemikari. Ihwo hutsva hwechokwadi hunenge husiri hwehupfu, hune simba hushoma hunofanana kana kudarika kushanda kwezinc + trivalent chromate. Isu hatisati tasvika. Mamwe ma bio-based kana epamberi polymer coatings anoratidza vimbiso mumaLab asi achishaya makumi emakore ekuvimbika-kwakasimbiswa mumunda izvo zvinoda indasitiri yezvisimbiso zvakakosha.

Imwe hiccup inoshanda ndeye galvanic corrosion. Kubatanidza a color-plated galvanized gasket nesimbi isinganyanyi kushanda (sesimbi isina tsvina) munzvimbo ine mvura inogona kukurumidza kuonda kwezingi. Iwe unofanirwa kurangarira nezve kubatanidza kwezvinhu. Ndakaona gasket rakarongedzwa zvakanaka richikundikana nekukurumidza nekuti rakaiswa pakati pemafurange maviri asina tsvina mugomba rinogara rakanyorova. Iyo gasket yakazvipira pachayo zvine hungwaru, asi iyo haisi mhedzisiro inoenderera. The takeaway? Hapana zvinhu zvinogadziriswa pasi rose. Kuitsanangura nemazvo ihafu yehondo.

Mhedziso: Nhanho yePragmatic, Kwete Panacea

Saka, kudzokera kumubvunzo wekutanga. Ko magasi akaiswa mavara ane mavara chinhu chitsva chakasimba here? Kubva pane zvinongoita, bhutsu-pa-pasi-maonero, ndingati ivo vanomiririra shanduko ye pragmatic kune mamwe maitiro ekugadzirisa akasimba. Ivo havasi revolutionary green tech. Mupiro wavo wekusimudzira unowanikwa kuburikidza nekuwedzera hupenyu hunoonekwa, shanduko yeindasitiri kune yakachengeteka trivalent chromates, uye nekushanda kwekuita kwavanogonesa kana ikashandiswa nemazvo.

Chinokosha ndechekuvaona sehurongwa: yemhando zinc base, yemazuva ano chromate layer, uye yakasimba yekugadzira zvigadziriso. Vatengesi vanonzwisisa izvi, sevaya vane zvivakwa zvakabatanidzwa munzvimbo dzekugadzira, ndivo vari kupa chivimbiso. Icho chishandiso. Uye sechishandiso chero chipi zvacho, kukosha kwayo - uye kusimba kwayo - kunotemerwa neruzivo uye chinangwa chemunhu arikushandisa. Regedza iyo hype, tarisa pane zvakatemwa zvekushandisa, uye zvinogona zvechokwadi kuve diki asi zvine musoro chikamu chekuvaka chakasimba, chisinga tambise maindasitiri maindasitiri. Ndihwo hutsva chaihwo: kushandura mafungire atinoita nezvechikamu chakazvininipisa mumufananidzo mukuru.
