Ungawathenga kuphi amabhawodi wokunweba alungele imvelo? 

Bheka, lapho osonkontileka abaningi noma abanye abaklami bezakhiwo bebuza mayelana namabhawodi okunweba alungele imvelo, ngokuvamile bafanekisela okuthile okugaywe kabusha noma okungabola. Lowo umbono wokuqala oyiphutha. Ekuqinisweni kwesakhiwo, "i-eco-friendly" ayimayelana nebhawodi elincibilika libe umquba. Kumayelana nawo wonke umjikelezo wempilo: ukutholwa kwezinto ezingavuthiwe, izinto ezikhishwayo ezikhiqizwayo, izinqubo zokumboza, ngisho nesisekelo sezinto ezisetshenziswayo. Uma nje useshela ibhawodi “eliluhlaza” ngaphandle kokuqonda imininingwane, uzogcina une-hardware enenani eliningi, engasebenzi kahle, noma okubi nakakhulu, into ewashiswe luhlaza. Ngikubonile kwenzeka kuphrojekthi ye-facade esezingeni eliphakathi nendawo e-Portland-i-bolt ebhalwe ukuthi "i-eco" esekelwe eshidini lomphakeli, ukuze ngithole ukuthi inqubo yayo yokugqoka i-zinc yayingenasici. Kusibize amasonto amabili ukubambezeleka. Ngakho-ke, uthola kuphi isivumelwano sangempela? Kuncane mayelana nesitolo esisodwa futhi okuningi mayelana nokulandela uchungechunge lokunikezela olubambekayo ngaphansi kokucutshungulwa.

Ukuchaza kabusha “I-Eco-Friendly” kuma-Fasteners

Ake sihlukanise ithemu. Ukuze uthole ibholithi yokunweba, umthelela wemvelo uqala esigayweni. Ingabe izinsimbi zensimbi zitholakala kubakhiqizi abanezinqubo eziqinisekisiwe zekhabhoni ephansi? Ezinye izigayo zase-Europe, ngokwesibonelo, zihlinzeka ngama-EPD (Izimemezelo Zomkhiqizo Wezemvelo) anemininingwane ekhipha ikhabhoni ngethani. Bese kuba ne-coating. I-galvanization evamile noma i-zinc plating ngokuvamile ihilela izinsimbi ezisindayo nama-asidi. I amabhawodi wokunweba alungele imvelo Ngithole ngempumelelo ngokuvamile ukuba ne-geometric coating-njenge-galvanizing yomshini esebenzisa ikhemistri encane-noma i-organic coating eqinisekisiwe njenge-Qualicoat Class I. Ayicwebezeli, kodwa ayishibhi.

Bese uba namandla okukhiqiza. Imboni esebenzisa i-solar noma emoyeni isika kakhulu ikhabhoni eshumekiwe kuyunithi ngayinye. Ngikhumbula ngihlola umkhiqizi waseShayina, I-Handan Zitai Fetesser Comment Co, Ltd., isikhashana emuva. Bazinze e-Yongnian, ihabhu le-fastener e-Hebei. Okwakugqama kwakungesona isikali sabo kuphela, kodwa ukushintshela kwabo ezithandweni zokungenisa ugesi ezivela kwezibaselwe ngamalahle. Lesi isinyathelo esibambekayo, nakuba sikhula. Indawo yabo eduze kwemizila emikhulu yezokuthutha efana ne-Beijing-Guangzhou Railway iyawehlisa uphethiloli wezokuthutha uma uhlanganisa ukuthunyelwa kwamabhokisi. Kodwa umbuzo wangempela uwukuthi: ingabe banalo ukucwaninga okuvela eceleni mayelana nezimangalo zabo zemvelo? Yilapho irabha ihlangana khona nomgwaqo.

Ukusebenza akukwazi ukudelelwa. Ibhawodi yokunweba ehlulekayo yinto esimeme kancane ongayicabanga—isho ukushintshwa, ukumosha, kanye nengozi engaba khona yesakhiwo. Ngakho-ke into esemqoka kufanele ihlangabezane noma yeqe amazinga e-ISO 898-1 mechanical property. Ngike ngahlola amabhawodi lapho inguqulo “eluhlaza” ibinamandla aphansi aqinile ngenxa yokungcola kwensimbi okugaywe kabusha. Isixazululo akukhona ukugwema okuqukethwe okugaywe kabusha, kodwa ukuqinisekisa ukuthi ingxubevange icwengisiswe kahle. Ibhalansi, futhi abahlinzeki abambalwa abafihli lutho ngalokhu kuhwebelana.

Ukuzulazula Eziteshini Zokuhlinzeka

Ngeke uthole amabhawodi okunweba ahlolwe ngempela e-eco-friendly kumthengisi onamabhokisi amakhulu. Abasabalalisi abavamile ngokuvamile abanakho ukujula kobuchwepheshe ukuze baphendule imibuzo yomjikelezo wempilo. Ngiqala ngabahlinzeki bezezimboni abakhethekile ababhekelela i-niche yokwakha eqhubekayo. Izinkampani ezifana ne-Fastenal noma i-Grainger zingase ziphathe umugqa, kodwa udinga ukumba emakhasini azo edatha yomkhiqizo futhi ngokuvamile uxhumane nomkhiqizi ngokuqondile. Izinkundla ze-B2B eziku-inthanethi ezifana ne-Thomasnet noma i-Alibaba zingaba amaphuzu okuqala, kodwa ziyinkundla yezimayini zezimangalo ezingaqinisekisiwe.

Umzila othembeke kakhulu ukuya ngqo ezimbonini ezinezinhlelo zokulawulwa kwemvelo ezifakazelwe (ISO 14001 isisekelo esihle). Ngokwesibonelo, lapho ngidinga amabhawodi okunweba ensimbi engagqwali angu-M12 anendawo ephansi yemvelo yephrojekthi ye-boardwalk yasogwini, ngabadlula bonke abaxhumanisi. Ngithinte I-Handan Zitai Fetesser Comment Co, Ltd. ngqo ngemva kokubona incazelo yenqubo yabo enemininingwane ku Iwebhusayithi yabo. Inzuzo yabo isesigabeni sokukhiqiza sengxenye enkulu kunazo zonke e-China, okusho ukuthi banokufinyelela kunethiwekhi yokuhlinzeka ngokugxilile, okungenzeka kunciphise ezokuthutha ezikhuphuka nomfula. Kodwa kwakusadingeka ngicele imibiko ethile yokuhlola mayelana nokujiya koqweqwe kanye nokumelana nokugqwala (amahora okuhlola isifutho sikasawoti). Bazinikeza, okwakuwuphawu oluhle.

Esinye isiteshi senziwa ngabakhi bezakhiwo noma izicacisi ezinemikhiqizo ehloliwe ngaphambilini. Amanye amafemu amakhulu onjiniyela agcina imininingwane yangaphakathi yezinto ezisimeme ezigunyaziwe. Ngithole ukuhola kwami ​​​​okungcono kakhulu koxhumana nabo ezingqungqutheleni zomkhakha, hhayi oseshweni lwewebhu. Omunye angase athi, "Sisebenzise lawa mabhawodi avela kumkhiqizi waseJalimane, i-fischer, kuphrojekthi yePassivhaus, futhi abene-EPD egcwele." Igolide lelo. Bese ubuyela emuva kumsabalalisi wabo wesifunda.

I-Certification Maze nokuthi Yini Empeleni Okubalulekile

Ukunikeza izitifiketi kungaba usizo noma ukumaketha nje. Bheka izimemezelo zemvelo zohlobo lwesithathu (EPDs) ezingalinganiseka. Ibhawodi eline-EPD lisho ukuthi othile uhlole umjikelezo wempilo yakhe kusukela ekuzalweni kuya esangweni. Amaphuzu e-LEED noma e-BREEAM avame ukuncika kumadokhumenti anjalo. Bese kuba nezitifiketi eziqondene nezinto ezibonakalayo—njenge-ResponsibleSteel yezinto ezingavuthiwe. Kodwa nakhu okubambekayo: kumaphrojekthi amancane, ukuthola lawa madokhumenti kumhlinzeki kungase kufane nokudonsa amazinyo. Abakhiqizi abaningi, ikakhulukazi e-Asia, basahlanganisa le mibhalo.

Ngikhumbula umphakeli ovela e-India ngokuziqhenya ebonisa ilebula ye-“Eco-Pro” kumabhawodi akhe okunweba. Ngemva kokucela isisekelo sesitifiketi, bathumele inqubomgomo yangaphakathi yekhasi elilodwa. Lokho akusizi. Ngokuphambene, abanye abakhiqizi baseYurophu banalo lonke iphakheji kodwa nge-premium yentengo engu-40-50%. Kufanele wahlulele ukuthi isabelomali sephrojekthi kanye negunya lokusimama kuyakuthethelela yini. Ngezinye izikhathi, okusebenzayo kakhulu amabhawodi wokunweba alungele imvelo yilezo lapho ubeka phambili isici esisodwa noma ezimbili eziyinhloko-njengokumboza okuhlanzekile kanye nokutholakala kwendawo ukuze unciphise ezokuthutha-kunokuba isixazululo esiphelele, esihlanganisa konke.

Ungakunaki ukupakisha. Kuzwakala kuncane, kodwa ngithole amabhawodi athunyelwe ngezikhwama zepulasitiki eziningi ngaphakathi kwebhokisi eligcwele i-styrofoam. Umkhiqizo ungase ube muhle, kodwa udoti wenqaba inzuzo enkulu. Manje ngicacisa ngokusobala ukupakisha okuncane, okungagaywa kabusha kuhlelo lokuthenga. Abanye abahlinzeki abaqhubekayo basebenzisa amakhadibhodi agaywe kabusha kanye nezihlukanisi ezisekelwe ephepheni. Kuyimininingwane encane ekhombisa ukuzibophezela kwangempela.

Izindleko vs. Inani: I-Real-World Trade-Off

Sikhulume ngemali. Izibophelelo eziluhlaza cishe njalo zibiza ngaphezulu. Umbuzo uwukuthi: liyini inani? Uma usebenza esakhiweni esiluhlaza esiqinisekisiwe, inani liyahambisana futhi linikela kulelo plaque lokugcina odongeni. Kuphrojekthi yezohwebo evamile, inani lingase libe sekwehliseni ingozi—igweme isibopho sezomthetho sesikhathi esizayo emithethweni evimbelayo yezemvelo ezintweni ezibonakalayo. Ngenze ukuhlaziya izindleko zeklayenti ngonyaka odlule: the amabhawodi wokunweba alungele imvelo wengeze cishe u-15% entweni yomugqa wokubopha. Kodwa uma kuqhathaniswa nengqikithi yezindleko zephrojekthi, yayingaphansi kuka-0.1%. Ukulandisa okulandisayo nokulawula kobufakazi besikhathi esizayo kwakuthengisa.

Nokho, kukhona umnotho wamanga. Ibhawodi “ye-eco” eshibhile egqwala eminyakeni emihlanu izokubiza ngokuphindwe kashumi emsebenzini wokulungisa. Lokhu ngikufunde kabuhlungu kuphrojekthi yokufakelwa kwangaphandle. Silondoloze u-$0.20 ngeyunithi ngayinye kumabhawodi anenamathela ephilayo engabazekayo. Phakathi neminyaka emithathu, kwavela amabala okugqwala esihlokweni. Uphenyo kanye nezindleko zokushintsha zanciphisa ukongiwa kokuqala. Manje, ngincamela ukukhokhela ibhawodi ebhizinisini elaziwayo elinjenge-Zitai, okungenani elinesilinganiso semboni nokulawula inqubo, bese ngiziqinisekisa ngokuzimela izimangalo zayo eziqondile eziluhlaza zesicelo sami.

Ukuthenga ngenqwaba umngane wakho. Umehluko wentengo yeyunithi uyancipha kakhulu uma u-oda umthwalo ogcwele wesiqukathi. Yilapho ukusebenza ngokuqondile nomkhiqizi endaweni efana ne-Yongnian kunengqondo. Ungakwazi ukuhlanganisa izinhlobo ezihlukene zokubopha zibe ukuthunyelwa okukodwa, wehlise i-carbon footprint yeyunithi ngayinye kusukela kwezokuthutha kanye namandla okuxoxisana ngemibandela engcono yezinto ezicaciswe kakhulu.

Izinyathelo Ezisebenzayo Zokuthenga Kwakho Okulandelayo

Ngakho, uzithenga kanjani ngempela? Okokuqala, bhala imininingwane ecacile. Ungamane uthi "eco-friendly." Cacisa izimfuneko: “Amabhawodi wokunweba we-M10, isigaba sendawo engumishini engu-8.8, anembongolo yejiyomethri noma i-organic coating eqinisekisiwe (hlinzeka ngezinga), athathwe kunsimbi enokuqukethwe okungenani okungu-50% okugaywe kabusha, okuhambisana ne-EPD noma isitifiketi sokugaya esichaza umkhondo wekhabhoni. Ukupakishwa kufanele kuphinde kusetshenziswe okungu-100%. Lokhu kuhlunga amaphesenti angama-80 abahlinzeki abangafanelekile ngokushesha.

Okwesibili, cela amasampula futhi uwahlole. Noma yimuphi umphakeli onedumela elihle uzohlinzeka ngamasampula. Zihlolele esakho isifutho sikasawoti uma kungenzeka, noma uzithumele elebhu yendawo. Hlola ukusebenza komshini. Ngihlale ngivivinya inqubo yokusetha-ngezinye izikhathi ukugqoka okuluhlaza kuthinta ukungqubuzana komkhono, okwenza ukufakwa kube nzima. Lokhu kwenzeka ngomkhiqizo waseDutch; ukunamathela kwakushelele kakhulu, futhi ibhawodi laphenduka ngesikhathi liqiniswa. Kwadingeka bahlele kabusha.

Ekugcineni, yakha ubuhlobo. Ukuthola umthombo othembekile we amabhawodi wokunweba alungele imvelo akuwona umcimbi wesikhathi esisodwa. Uma uthola umphakeli osobala futhi ongaguquki, namathela kuye. Kungakhathaliseki ukuthi uhlobo olukhethekile lwaseYurophu noma umkhiqizi omkhulu onjalo I-Handan Zitai Fetesser Comment Co, Ltd. lokho okuthuthukisa ngenkuthalo izinqubo zayo, ukuqhubeka konga isikhathi futhi kunciphisa ubungozi kumaphrojekthi wesikhathi esizayo. Umgomo akukhona ukuthola umkhiqizo ophelele, kodwa ukuthola uzakwethu onokwethenjelwa ochungechungeni lokuhlinzeka oqonda ukuhlangana kokusebenza nokusimama, futhi ozimisele ukukufakazela lokho.
