Zvikamu zvakaiswa mugreen tech? 

Kana vanhu vachitaura nezve green tech, vanowanzo fananidzira solar panel, wind turbines, kana EV mabhatiri. Hapana anofunga nezvazvo zvikamu zvakabatanidzwa - zvibatiso, zvinoiswa, tambo dzakarukwa dzinobata aya makuru makuru pamwe chete. Ndiyo nzvimbo yebofu yakajairika. Muchokwadi, kana izvi zvikamu zvikatadza, iyo yese 'yegirini' system inogona kuuya ichidonha, chaizvo. Chiitiko changu chave chekuti kusimba kwepurojekiti kunowanzoenderana neaya asina kunaka, akavigwa zvimedu zvehardware. Haisi kungoshandisa simbi yakadzokororwa; ndezvekuvainjiniya kuti vagare makore makumi matatu munzvimbo inoparadza yekumahombekombe kana pasi pekugara vachichovha bhasikoro. Ndipo pane dambudziko chairo.

Kusanzwisisana kwe 'Ingori Bolt'

Ndakagara mumisangano uko kutenga kunosundidzira iyo yakaderera-inodhura fastener ye solar purazi rekuisa system. Iyo pfungwa iri nyore: ingori simbi, yakavigwa mukongiri, ingave yakakosha sei? Izvi zvinoderedza zvine njodzi. A galvanized chikamu chakaiswa muvhu rine high chloride content inogona kuora nekukurumidza kupfuura zvanga zvichitarisirwa. Ndakaona mapurojekiti ekudzoreredza uko hurongwa hwese hwaifanira kubviswa nekuti zvibatiso zvepasi zvakakanganiswa. Mutengo wekutsiva iwo zvikamu zvakabatanidzwa yakapfuura mari yekutanga yakachengetwa nekagumi. Icho chidzidzo mumutengo wakazara wevaridzi iyo indasitiri ichiri kudzidza zvishoma nezvishoma.

Iyo yakatarwa ndeye zvese. Kune ichangoburwa agro-voltaic purojekiti, hatina kukwanisa kushandisa standard hot-dip galvanizing. Iyo ammonia inonyungudika kubva muminda yepurazi pasi pemapanera yakagadzira njodzi yekuora kwemhepo. Takazopedzisa kutsanangura duplex coating system - zinc pamwe nepolymer sealant - kune vese simbi yakadzikwa zvikamu. Hwaiva hudzama, asi kuhukanganisa kungadai kwakatungamirira kukukundikana nokukurumidza uye ivhu rakasvibiswa. Iyo yakasvibira chimiro haisi simba rinogadzirwa chete; iri kuona kuti kuiswa hakugadziri dambudziko remarara remangwana kana dambudziko rekusvibisa.

Apa ndipo pane zvakakosha vagadziri. Iwe unoda mutengesi anonzwisisa izvi zvinonetsa kwezvakatipoteredza, kwete iye chete anobaya kunze kwakajairika M20 tsvimbo. Ndakashanda nemafekitari anozviwana. Semuyenzaniso, Handan Zitai Fastener Manufacturing Co., Ltd., yakavakirwa muChina hombe yekugadzira chinomisikidza hub muYongnian, Handan, inowanzoita nezveizvi zvikumbiro, zvinoenderana nenharaunda. Nzvimbo yavo padhuze nemigwagwa mikuru yekufambisa ndeye mukana unoshanda wezvinhu, asi kugona kwavo kuita pamachira ehunyanzvi uye mamakisi emidziyo anovaita mutambi akakodzera. Hazvirevi zve-off-the-sherufu zvigadzirwa; inyaya yekudyidzana kugadzirisa matambudziko embedded applications.

Case in Point: Iyo Inoyangarara Solar Headache

Inoyangarara PV chikamu chiri kukura. Wese munhu anotarisa pane iyo pontoon zvinhu uye nepaneru kushanda zvakanaka. The nightmare? The simbi isina tsvina mabhuraketi anobatanidza mafuremu epaneru kumadhoko anoyangarara. Mvura yakachena chinhu chimwe, asi mudura rebrackish, une dutu rakakwana: unyoro hunogara huripo, oxygen, uye chlorides. Isu takatsanangura 316 isina tsvina yepurojekiti, tichifunga kuti ndeyekuchengetedza.

Makore maviri mukati, takawana kushushikana kwecorrosion kutsemuka panzvimbo dzeweld dzemabhuraketi akaiswa. Iyo nyaya yanga isiri iyo yekutanga zvinhu, asi iyo yekupisa mhedzisiro kubva kune welding panguva yekuungana, iyo yakashandura iyo microstructure munzvimbo yakakanganiswa nekupisa, ichiita kuti ive nyore munzvimbo iyoyo chaiyo. Kugadziriswa kwacho kwaive kusiri kudiki: kuchinjika kune premium-giredhi isina tsvina ine yakakwira molybdenum zvemukati uye kumanikidza yakasimba post-weld kurapwa mapuroteni kune vese. zvikamu zvakabatanidzwa. Yakapaza gomba mubhajeti asi yakachengetedza chirongwa.

Izvi zvinosvika kune yakakosha musimboti: zvikamu zvakabatanidzwa mune green tech masisitimu, kwete zvigadzirwa. Kuita kwavo kwakabatana nesainzi yezvinhu, kugadzira, nzira yekuisa, uye chaiyo nharaunda-yavanogara. Haukwanise kuaongorora ari ega kubva kune mamwe einjiniya dhizaini. Iyo inoyangarara solar kesi yakandidzidzisa kuti ndigare ndichibatanidza yekusimbisa kana yakamisikidzwa zvikamu nyanzvi padanho reCAD, kwete nhanho yekutenga.

Huremu hweZvinotarisirwa uye Chokwadi

Pane kudzvanyirira kukuru kuita ese egirinhi tekinoroji chirongwa 'girinhi,' kusanganisira iyo zvikamu zvakabatanidzwa. Izvi zvinotungamira mukusundirwa kwezvinhu zvitsva senge bio-based composites kana zvakanyanya nyowani alloys. Ini ndiri zvese zvekuvandudza, asi ndakaonawo kutadza kwemutyairi. Takaedza danda resimba repamusoro-soro mumunda wepombi yekupisa yegeothermal. Dzidziso yacho yakanga yakakwana: isina-corrosive, yakaderera-embodied carbon.

Mukuita, kusiyanisa kwekuwedzera kwekupisa pakati pemudonzvo weboka uye yakapoteredza kongiri grout yakagadzira micro-fractures pamusoro pemwedzi 18 chete, zvichibvumira mvura kupinda uye zvichiita kuti kurasikirwa kwemaitiro ekubata. Takadzokera kune imwe simbi yechinyakare, inodzivirirwa nesimbi. Chidzidzo chaive chisiri chekudzivisa zvinhu zvitsva, asi kuzviyedza pasi pesero yakazara, chaiyo-yepasirese kushushikana uye kutenderera kwezvakatipoteredza, kwete chete mamiriro emurabhoritari. Iyo 'greenness' yechikamu chinotadza kutanga i zero.

Dzimwe nguva, sarudzo yakasimba ndeye yakasimba, yakanyatsotsanangurwa yechinyakare zvinhu. Kureba kwayo kunodzivirira kutsiva, kuchera, uye kugadzirisa zvinhu zvitsva. Iyi ongororo yehupenyu iri kuve yakakosha. Tave kutanga kukumbira Environmental Product Declarations (EPDs) zvehukuru zvinhu zvakaiswa, iyo iri kusundira vagadziri kuti vape data rakajeka pane maitiro avo. Iko kushanduka kunononoka, asi iri kufambisa tsono kubva kune zvisina kujeka zvirevo kuenda kune zvinogoneka specs.

Logistics uye iyo On-Site Gamble

Tsanangudzo hapana anotaura nezvayo kudzamara vasvika pasaiti iri kure: kurongedza uye kuzivikanwa. Iwe unohodha 50 mapallets etsika zvibatiso zvakadzikwa yepurazi remhepo. Ivo vanosvika, uye iwo kupisa-nhamba ma tag ekuteedzera zvinhu anogezwa kubva kumvura panguva yekufambisa, kana zvivharo zvekudzivirira zvemigumo yakarukwa zvisipo. Ikozvino une batch yezvinodhura, mishoni-yakakosha zvikamu zvine kuchengetedzwa kwecorrosion uye hapana nzira yekusimbisa chitupa chavo. Iwe unovaisa uye unotarisira, kana kunonoka nheyo inodururwa nemavhiki?

Ndakatarisana neizvi. Takasarudza kunonoka. Ngozi yekuisa chikamu chisina kusimbiswa, kunyanya mukuneta-yakakosha application senge mhepo turbine base, iripo. Ikozvino, chinhu chemutsara muzvibvumirano zvedu zvevashambadziri: edziviriro yekurongedza zviyero uye zvachose, yemamiriro ekunze-uchapupu nzira dzekuzivikanwa. Kutarisisa kwemutengesi kune aya emazuva ese ruzivo kazhinji kacho dhizaini yemhando yavo yese tsika. Kureruka kwenzvimbo yemutengesi, senge Handan Zitai Fastener ari padyo nemigwagwa mikuru nenjanji, zvine basa chete kana zvikamu zvasvika panzvimbo yagadzirira.

Izvi zvinowedzera kusvika pakuiswa. Isu takave nevashandi vakashandisa zvisizvo mawrenches pane yakapfava zvakaiswa mukati yakagadzirirwa kusungirirwa kwemaoko, kubvisa tambo uye kuita kuti zvive zvisina maturo. Mukana wekudzidzira pakati peinjiniya yezvimiro, mugadziri wezvikamu, uye vashandi vemunda injodzi chaiyo. Takatanga kugadzira mapfupi, ane mifananidzo ekuisa madhairekitori mumitauro yakawanda kune yega yega yakamisikidzwa chikamu. Zvinoita sezviri pachena, asi zvakazvarwa kubva kune zvinodhura zvikanganiso zvemunda.

Kutarisa Mberi: Kubatanidzwa ndicho Kiyi

Ramangwana re zvikamu zvakabatanidzwa mune green tech haisi yekungopfeka zviri nani. Zviri pamusoro pekubatanidza zvine hungwaru. Ndiri kuona kufarira kwakawanda kune 'zvakaridzwa' anchors kana tsvimbo ine yakavakirwa-mukati fiber optics yekutarisa kusagadzikana uye ngura munguva-chaiyo, kunyanya mune geothermal kana offshore application. The chikamu chakaiswa inova murindi wehutano hwese chimiro.

Imwe nzira ndeyekugadzira yekubvisa. Can the simbi yakadzikwa kubviswa nyore nyore uye kudzokororwa pamagumo-e-hupenyu, kana kuti yakarongerwa kuraswa kwemarara? Tiri kuyedza nezve zvibayiro corrosion link uye mechanical anchor masisitimu anobvumira disassembly, ichifamba kupfuura echinyakare 'cast-in-and-forget' mafungiro. Uyu ndiwo muganho unotevera wekutenderera mumunda wedu.

Pakupedzisira, basa rezvikamu izvi riri kutsanangurwa patsva. Ivo vari kushandura kubva pane passive, zvakavanzika zvinhu kuenda kune zvinoshanda, zvinoratidzwa zvinhu zvegirinhi asset. Izvi zvinoda hukama hwepedyo pakati pegirinhi tekinoroji vanogadzira, mainjiniya ezvimiro, uye rudzi rutsva rwevagadziri vezvikamu zvehunyanzvi vanofunga mumasystem, kwete zvidimbu chete. Makambani anonzwisisa shanduko iyi - anoona mabhaudhi uye zvibatiso zvawo seakakosha pakugara kwenguva refu uye kusimba kwechokwadi kweprojekiti - ndiwo anozoiswa mukati, pun yakarongwa, mune ramangwana reindasitiri.
