Uzithenga phi iibholithi zokwandiswa kwe-eco-friendly? 

Jonga, xa uninzi lweekontraka okanye abanye abayili bezakhiwo bebuza malunga ne-eco-friendly bolts yokwandiswa kweebholithi, bahlala bebonisa into ephinda isetyenziswe okanye inokubola. Leyo yimpazamo yokuqala. Ekuqinisweni kolwakhiwo, "i-eco-friendly" ayithethi malunga nebholithi enyibilikayo ibe ngumgquba. Imalunga nomjikelo wobomi uphela: ukufunwa kwemathiriyeli ekrwada, ukukhutshwa kwezinto ezikhutshwayo, iinkqubo zokugquma, kunye nesiseko solungiselelo. Ukuba ukhangela nje ibholithi "eluhlaza" ngaphandle kokuqonda i-specs, uya kuphelela ngexabiso elingaphezulu, i-hardware engasebenziyo, okanye okubi ngakumbi, into ehlanjwe luhlaza. Ndiyibonile isenzeka kwiprojekthi ye-facade ephakathi e-Portland-spec'd i-bolt ebhalwe "eco" esekwe kwiphepha lomboneleli, kuphela ukufumanisa ukuba inkqubo yayo yokucoca i-zinc yayingacocekanga. Kusidle iiveki ezimbini zokulibaziseka. Ke, uyifumana phi eyona nyani? Incinci malunga nevenkile enye kwaye ngaphezulu malunga nokulandela ikhonkco lokubonelela elibambe phantsi koqwalaselo.

Ukuchaza kwakhona "i-Eco-Friendly" kwiiFasteners

Makhe sihlolisise igama. Kwibholithi yokwandisa, impembelelo yokusingqongileyo iqala kwindawo yokusila. Ingaba iintonga zentsimbi zithathwe kubavelisi abaneendlela eziqinisekisiweyo ezinekhabhoni ephantsi? Ezinye izixhobo zokusila zaseYurophu, umzekelo, zibonelela ngee-EPDs (Izibhengezo zeMveliso yokuSingqongileyo) ezichaza imveliso yekhabhoni ngetoni nganye. Emva koko kukho i-coating. I-galvanization eqhelekileyo okanye i-zinc plating ihlala ibandakanya isinyithi esinzima kunye ne-asidi. I iibholithi zokwandisa eco-friendly Ndiyifumene ngempumelelo ngokuqhelekileyo i-geometric coating-like galvanizing mechanical esebenzisa i-chemistry encinci-okanye i-certified organic coating efana ne-Qualicoat Class I. Ayinakukhanya, kodwa ayifuni.

Emva koko unamandla okuvelisa. Umzi-mveliso osebenza kwilanga okanye emoyeni usika kakhulu ikhabhoni edibeneyo kwiyunithi nganye. Ndikhumbula ndivavanya umenzi waseTshayina, I-Sunnian Zitai Festener Fishaner Comment Com., umzuzwana emva. Bazinze eYongnian, ihabhu yokuqinisa eHebei. Eyona nto yayibalasele yayingengomlinganiselo wabo kuphela, kodwa ukutshintshela kwabo kwiziko lombane lokusebenzisa amalahle. Eli linyathelo elibambekayo, nangona liyakhula. Indawo yabo kufutshane neendlela ezinkulu zezothutho ezifana neBeijing-Guangzhou Railway iyawanciphisa amafutha ezithuthi ukuba udibanisa ukuthunyelwa kweenkonkxa. Kodwa owona mbuzo ngulo: ngaba banalo uphicotho lomntu wesithathu ngamabango abo okusingqongileyo? Kulapho irabha idibana khona nendlela.

Ukusebenza akunako ukuncama. Ibholithi yokwandisa engaphumeleliyo yeyona nto incinci inokucingeleka-ithetha ukutshintshwa, inkcitho, kunye nomngcipheko onokubakho wesakhiwo. Ngoko ke imathiriyeli engundoqo kufuneka ihlangabezane okanye idlule imigangatho yepropathi yoomatshini ye-ISO 898-1. Ndiye ndavavanya iibholiti apho inguqulelo “eluhlaza” ibinamandla asezantsi okuqina ngenxa yobumdaka obusetyenzisiweyo bentsimbi. Isisombululo asikokuphepha umxholo ohlaziyiweyo, kodwa kukuqinisekisa ukuba i-alloy icocwe ngokufanelekileyo. Kuyibhalansi, kwaye bambalwa ababoneleli abaselubala malunga nolu rhwebo.

Ukujonga kwimijelo yokuBonelela

Awuyi kufumana iibholithi zokwandiswa kwe-eco-friendly ngokwenene kumthengisi webhokisi enkulu. Abasasazi abaqhelekileyo bahlala bengenabo ubunzulu bobugcisa bokuphendula imibuzo yobomi. Ndiqala ngababoneleli bemizi-mveliso abakhethekileyo ababonelela kwi-niche yokwakha ezinzileyo. Iinkampani ezinjengeFastenal okanye iGrainger zinokuthwala umgca, kodwa kufuneka umbe kumaphepha edatha yemveliso kwaye uhlala unxibelelana ngqo nomenzi. Amaqonga e-B2B akwi-Intanethi afana noThomasnet okanye i-Alibaba inokuba ngamanqaku okuqalisa, kodwa ziindawo zemigodi yamabango angaqinisekiswanga.

Indlela ethembeke ngakumbi kukuya ngqo kwiifektri ezineenkqubo zolawulo lokusingqongileyo eziqinisekisiweyo (ISO 14001 sisiseko esilungileyo). Umzekelo, xa ndandifuna iibholithi zokwandiswa kwentsimbi engenastainless M12 enendawo ephantsi yokusingqongileyo kwiprojekthi yolwakhiwo lwaselunxwemeni, ndagqitha kubo bonke abalamli. Ndaqhagamshelana I-Sunnian Zitai Festener Fishaner Comment Com. ngqo emva kokubona inkcazo yenkqubo eneenkcukacha kwi iwebhusayithi yabo. Inzuzo yabo ikukuba kweyona ndawo inkulu yomgangatho wemveliso e-China, okuthetha ukuba banokufikelela kuthungelwano lonikezelo olugxininisiweyo, okunokunciphisa uthutho olunyukayo. Kodwa bekusafuneka ndicele iingxelo zovavanyo ezithile malunga nobukhulu bokugquma kunye nokumelana nomhlwa (iiyure zovavanyo lwesitshizi setyuwa). Bazilungiselela, nto leyo eyayiluphawu oluhle.

Elinye ijelo lenziwa ngabayili bezakhiwo okanye abacacisi abaneemveliso ezivavanyiweyo kwangaphambili. Ezinye iifemu ezinkulu zobunjineli zigcina ugcino-lwazi lwangaphakathi lwemathiriyeli evunyiweyo ezinzileyo. Ndifumene izikhokelo zam ezilungileyo kubafowunelwa kwiinkomfa zeshishini, hayi kukhangelo lwewebhu. Omnye umntu unokukhankanya, "Sisebenzise ezi bholiti zivela kumenzi waseJamani, i-fischer, kwiprojekthi yePassivhaus, kwaye babene-EPD epheleleyo." Yigolide leyo. Emva koko ubuyela emva kumthengisi wabo wengingqi.

Imaze yezatifikethi kunye neyona nto ibalulekileyo

Izatifikethi zinokuba luncedo okanye ukuthengisa nje. Khangela uHlobo lwe-III lwezibhengezo zokusingqongileyo (EPDs) ezinokulinganiswa. Ibholithi ene-EPD ithetha ukuba umntu uphicothe umjikelo wobomi bakhe ukusuka kwimbeleko ukuya esangweni. Amanqaku e-LEED okanye e-BREEAM ahlala exhomekeke kumaxwebhu anjalo. Ke kukho ii-certs ezicacileyo-ezinje ngeResponsibleSteel yemathiriyeli ekrwada. Kodwa nantsi into yokubamba: kwiiprojekthi ezincinci, ukufumana la maxwebhu kumthengisi kunokufana nokutsala amazinyo. Abavelisi abaninzi, ngakumbi e-Asiya, basawanyusa la maxwebhu.

Ndikhumbula umthengisi ovela eIndiya ngokuzingca ebonisa ileyibhile "Eco-Pro" kwiibholithi zabo zokwandisa. Emva kokucela isiseko sesatifikethi, bathumela umgaqo-nkqubo wangaphakathi wephepha elinye. Loo nto ngamampunge. Ngokwahlukileyo, abanye abavelisi baseYurophu banephakheji epheleleyo kodwa ngexabiso leprimiyamu ye-40-50%. Kuya kufuneka ugwebe ukuba uhlahlo lwabiwo-mali lweprojekthi kunye nesigunyaziso sozinzo siyayithethelela. Ngamanye amaxesha, eyona isebenzayo iibholithi zokwandisa eco-friendly zezo apho ubeka phambili into enye okanye ezimbini eziphambili-njengengubo ecocekileyo kunye nokukhangela kwendawo ukusika ukuthutha-kunokuba isisombululo esipheleleyo, esiquka zonke.

Musa ukungayihoyi ukupakishwa. Kuvakala kuncinci, kodwa ndifumene iibholiti ezithunyelwe kwiingxowa ezininzi zeplastiki ngaphakathi kwebhokisi ezaliswe yi-styrofoam. Imveliso inokuba nkulu, kodwa inkunkuma iyala inzuzo eninzi. Ngoku ndicacisa ngokucacileyo ukupakishwa okuncinci, okunokuphinda kusetyenziswe kwi-oda lokuthenga. Abanye ababoneleli ngenkqubela basebenzisa ikhadibhodi ehlaziyiweyo kunye nezahluli ezisekelwe ephepheni. Yinkcukacha encinci ebonisa ukuzinikela kwangempela.

Iindleko vs. Ixabiso: Urhwebo lweHlabathi lokwenyani

Masithethe ngemali. Iifasteners eziluhlaza phantse zihlala zibiza ngaphezulu. Umbuzo ngulo: yintoni ixabiso? Ukuba usebenza kwisakhiwo esiluhlaza esiqinisekisiweyo, ixabiso lihambelana nokuthotyelwa kunye negalelo kwi-plaque yokugqibela eludongeni. Kwiprojekthi yorhwebo eqhelekileyo, ixabiso linokuba kukuncitshiswa komngcipheko-ukuphepha uxanduva lwexesha elizayo kwimimiselo ethintelayo yokusingqongileyo kwizinto eziphathekayo. Ndenze uhlalutyo lweendleko kumthengi kunyaka ophelileyo: i iibholithi zokwandisa eco-friendly yongezwe malunga ne-15% kwinto yomgca we-fastener. Kodwa xa kubalwa kwiindleko zeprojekthi iyonke, ibingaphantsi kwe-0.1%. Ibali kunye nokulawula ikamva-proofing wayithengisa.

Nangona kunjalo, kukho uqoqosho lobuxoki. Ibhawunti yexabiso eliphantsi "ye-eco" ebolayo kwiminyaka emihlanu iya kukubiza ngokuphindwe kalishumi kumsebenzi wokulungisa. Oku ndikufunde kabuhlungu kwiprojekthi yokugquma yangaphandle. Sigcine i-0.20 yeedola kwiyunithi nganye kwiibholiti ezinombala othandabuzekayo wendalo. Kwisithuba seminyaka emithathu, kwavela amabala omhlwa kwintsimbi. Uphando kunye neendleko zokubuyisela ziye zanciphisa ulondolozo lokuqala. Ngoku, ndingathanda ukuhlawulela ibholithi evela kwiziko elaziwayo elinjengeZitai, elinomlinganiselo weshishini kunye nolawulo lwenkqubo, kwaye ke ngokuzimeleyo ndiqinisekise amabango alo aluhlaza kwisicelo sam.

Ukuthenga izinto ezininzi ngumhlobo wakho. Umahluko wexabiso leyunithi ucutheka kakhulu xa u-odola umthwalo ogcweleyo wesikhongozeli. Kulapho ukujongana ngqo nomvelisi kwindawo efana neYongnian kunengqiqo. Ungadibanisa iindidi ezahlukeneyo zokuqhoboshela kuthutho olunye, unciphise iyunithi nganye yekhabhoni yonyawo ukusuka kuthutho kunye nokubanakho uthethathethwano ngemibandela engcono yezinto eziphezulu.

Amanyathelo asebenzayo okuthenga kwakho okulandelayo

Ngoko ke, uzithenga njani ngokwenene? Okokuqala, bhala iinkcukacha ezicacileyo. Musa nje ukuthi "i-eco-friendly." Cacisa iimfuno: "Iibholithi zokwandisa i-M10, iklasi yepropathi ye-mechanical 8.8, ene-geometric coating okanye i-certified organic coating (ubonelelo olusemgangathweni), oluthathwe kwintsimbi enomxholo ohlaziyiweyo we-50%, ehamba ne-EPD okanye isatifikethi sokusila esichaza i-carbon footprint. Ukupakishwa kufuneka kube yi-100% enokuphinda isetyenziswe." Oku kucoca i-80% yababoneleli abangenaziqinisekiso ngoko nangoko.

Okwesibini, cela iisampuli kwaye uzivavanye. Nawuphi na umthengisi othembekileyo uya kunika iisampuli. Yenza olwakho uvavanyo lwesitshizi setyuwa ukuba kunokwenzeka, okanye uzithumele kwilebhu yendawo. Jonga ukusebenza koomatshini. Ndihlala ndivavanya inkqubo yokumisela-ngamanye amaxesha i-coating eluhlaza ichaphazela i-friction kwi-sleeve, okwenza ukufakela kube nzima. Oku kwenzeka ngemveliso yaseDatshi; Ukwaleka kwakutyibilika kakhulu, kwaye ibholithi yajikeleza ngexesha lokuqina. Kwakufuneka bahlengahlengise.

Ekugqibeleni, yakha ubudlelwane. Ukufumana umthombo othembekileyo we iibholithi zokwandisa eco-friendly ayisosiganeko sexesha elinye. Xa ufumana umthengisi ocacileyo kwaye ongaguqukiyo, namathela kuye. Nokuba luphawu olukhethekileyo lwaseYurophu okanye umvelisi omkhulu onjalo I-Sunnian Zitai Festener Fishaner Comment Com. leyo iphucula ngenkuthalo iinkqubo zayo, ukuqhubeka konga ixesha kwaye kunciphisa umngcipheko kwiiprojekthi ezizayo. Injongo ayikukufumana imveliso egqibeleleyo, kodwa ukufumana iqabane elithembekileyo kwikhonkco lokubonelela eliqonda ukuhlangana kokusebenza kunye nokuzinza, kwaye uzimisele ukungqina.
