Qhov twg yuav eco-phooj ywg expansion bolts? 

Saib, thaum feem ntau cov neeg cog lus lossis qee tus kws tsim vaj tsev nug txog eco-friendly expansion bolts, lawv feem ntau pom cov khoom siv rov ua dua lossis tej zaum biodegradable. Qhov ntawd yog thawj qhov kev xav tsis zoo. Nyob rau hauv cov qauv fastening, "eco-friendly" tsis yog hais txog lub bolt dissolving rau hauv compost. Nws yog hais txog tag nrho lub neej voj voog: kev nrhiav cov khoom siv raw, kev tsim tawm emissions, txheej txheem txheej, thiab txawm tias logistics hneev taw. Yog tias koj tab tom nrhiav rau "ntsuab" ntsia liaj qhov rooj yam tsis nkag siab cov specs, koj yuav xaus nrog cov khoom siv tsis zoo, tsis zoo, lossis phem dua, ib yam dab tsi uas tau ntxuav. Kuv tau pom nws tshwm sim ntawm qhov project façade nruab nrab hauv Portland - spec'd lub bolt sau "eco" raws li tus neeg muag khoom daim ntawv, tsuas yog kom paub tias nws cov txheej txheem zinc plating yog dab tsi tab sis huv. Nqi peb ob lub lis piam nyob rau hauv ncua. Yog li, qhov twg koj yeej pom qhov tiag tiag? Nws tsawg dua ntawm ib lub khw muag khoom thiab ntau ntxiv txog kev taug qab cov saw hlau uas tuav tau nyob rau hauv kev tshuaj xyuas.

Redefining "Eco-Friendly" hauv Fasteners

Cia peb tawg lub sij hawm. Rau kev nthuav dav ntsia liaj qhov rooj, kev cuam tshuam ib puag ncig pib ntawm lub zeb. Puas yog cov hlau rods tau txais los ntawm cov neeg tsim khoom nrog kev kuaj xyuas cov pa roj carbon tsawg? Ib txhia European mills, piv txwv li, muab EPDs (Environmental Product Declarations) uas qhia txog cov pa roj carbon ntau ib tuj. Tom qab ntawd muaj txheej txheej. Txheem galvanization lossis zinc plating feem ntau suav nrog cov hlau hnyav thiab cov kua qaub. Cov eco-phooj ywg expansion bolts Kuv tau txais kev vam meej feem ntau muaj cov txheej txheej geometric-xws li cov khoom siv galvanizing uas siv cov chemistry tsawg-lossis cov ntawv pov thawj organic zoo li Qualicoat Class I. Nws tsis yog ci, tab sis nws tsis leaching.

Tom qab ntawd koj muaj lub zog tsim khoom. Lub Hoobkas khiav ntawm hnub ci lossis cua tau txiav cov pa roj carbon monoxide hauv txhua chav. Kuv nco qab ntsuam xyuas cov chaw tsim khoom hauv Suav teb, HANDAN ZITAI FREWER RAUG UA MOV., Ltd., ib pliag rov qab. Lawv nyob hauv Yongnian, qhov chaw nrawm nrawm hauv Hebei. Dab tsi sawv tawm tsis yog lawv qhov ntsuas xwb, tab sis lawv txoj kev hloov mus rau hluav taws xob induction rauv taws los ntawm cov hluav taws xob hluav taws xob. Qhov ntawd yog ib qho tangible, txawm tias incremental, kauj ruam. Lawv qhov chaw nyob ze cov kev thauj loj xws li Beijing-Guangzhou Railway txo cov roj tsheb thauj mus los yog tias koj tab tom sib sau cov thawv xa khoom. Tab sis cov lus nug tiag tiag yog: lawv puas muaj kev tshuaj xyuas thib peb rau lawv qhov kev thov ib puag ncig? Qhov ntawd yog qhov uas cov roj hmab ntsib txoj kev.

Kev ua tau zoo tsis tuaj yeem txi. Ib qho kev nthuav dav uas ua tsis tau yog qhov tsawg tshaj plaws uas xav tau - nws txhais tau tias hloov pauv, pov tseg, thiab muaj peev xwm ua rau muaj kev pheej hmoo. Yog li cov khoom siv tseem ceeb yuav tsum ua kom tau raws li lossis dhau ISO 898-1 cov qauv khoom siv tshuab. Kuv tau sim bolts qhov twg "ntsuab" version muaj lub zog tensile qis vim yog siv cov hlau tsis huv. Kev daws tsis yog kom zam cov ntsiab lus rov ua dua tshiab, tab sis kom ntseeg tau tias cov hlau ua kom zoo zoo. Nws yog qhov sib npaug, thiab ob peb tus neeg muag khoom tau pob tshab txog qhov kev sib pauv no.

Nrhiav cov khoom siv channel

Koj yuav tsis pom tiag tiag vetted eco-friendly expansion bolts ntawm lub khw muag khoom loj. Cov neeg muag khoom tseem ceeb feem ntau tsis muaj qhov tob tob los teb cov lus nug txog lub neej. Kuv pib nrog cov chaw tsim khoom tshwj xeeb uas ua rau kev tsim kho kom ruaj khov. Cov tuam txhab xws li Fastenal lossis Grainger tuaj yeem nqa ib txoj kab, tab sis koj yuav tsum tau khawb rau hauv lawv cov ntaub ntawv cov ntaub ntawv thiab feem ntau hu rau cov chaw tsim khoom ncaj qha. Online B2B platforms zoo li Thomasnet lossis txawm Alibaba tuaj yeem pib cov ntsiab lus, tab sis lawv yog minefields ntawm kev tsis lees paub.

Txoj kev txhim khu kev qha ntau dua yog mus ncaj qha rau cov chaw tsim khoom nrog cov pov thawj ib puag ncig kev tswj hwm (ISO 14001 yog lub hauv paus zoo). Piv txwv li, thaum kuv xav tau M12 stainless hlau expansion bolts nrog ib puag ncig tsis tshua muaj hneev taw rau txoj haujlwm taug kev ntug hiav txwv, kuv hla txhua tus neeg nruab nrab. kuv hu rau HANDAN ZITAI FREWER RAUG UA MOV., Ltd. ncaj qha tom qab pom lawv cov ncauj lus kom ntxaws txheej txheem piav qhia ntawm lawv lub vev xaib. Lawv qhov zoo dua yog nyob rau hauv cov txheej txheem loj tshaj plaws ntawm kev tsim khoom hauv Suav teb, uas txhais tau hais tias lawv tau nkag mus rau cov khoom siv sib xyaw ua ke, muaj peev xwm txo qis kev thauj mus los. Tab sis kuv tseem yuav tsum tau thov cov ntawv ceeb toom tshwj xeeb ntawm cov txheej thickness thiab corrosion kuj (xws li tshuaj tsuag ntsev). Lawv muab rau lawv, uas yog ib qho cim zoo.

Lwm channel yog los ntawm architects los yog specifiers uas muaj pre-vetted khoom. Qee lub tuam txhab engineering loj tuav cov ntaub ntawv sab hauv ntawm cov ntaub ntawv pom zoo. Kuv tau txais kuv cov thawj coj zoo tshaj plaws los ntawm kev sib cuag ntawm cov rooj sib tham hauv kev lag luam, tsis yog los ntawm kev tshawb nrhiav lub vev xaib. Qee tus neeg yuav hais tias, "Peb siv cov ntsia hlau no los ntawm lub chaw tsim khoom German, fischer, ntawm Passivhaus project, thiab lawv muaj EPD tag nrho." Qhov ntawd yog kub. Tom qab ntawd koj taug qab rov qab mus rau lawv tus neeg faib khoom hauv cheeb tsam.

Daim Ntawv Pov Thawj Maze thiab Dab Tsi Tiag Tiag

Cov ntawv pov thawj tuaj yeem pab tau lossis tsuas yog kev lag luam xwb. Nrhiav Hom III ib puag ncig declarations (EPDs) uas yog quantifiable. Lub ntsia liaj qhov rooj muaj EPD txhais tau hais tias ib tug neeg tau tshawb xyuas nws lub voj voog ntawm lub txaj mus rau lub rooj vag. LEED lossis BREEAM cov ntsiab lus feem ntau khawm ntawm cov ntaub ntawv no. Tom qab ntawd muaj cov ntaub ntawv pov thawj tshwj xeeb-xws li Lub Luag HaujlwmSteel rau cov khoom siv raw. Tab sis ntawm no yog qhov ntes: rau cov haujlwm me me, tau txais cov ntaub ntawv no los ntawm tus neeg muag khoom tuaj yeem zoo li rub cov hniav. Ntau lub tuam txhab, tshwj xeeb hauv Asia, tseem tab tom txhim kho cov ntaub ntawv no.

Kuv nco qab tus neeg muag khoom los ntawm Is Nrias teb zoo siab nthuav tawm "Eco-Pro" daim ntawv lo ntawm lawv cov bolts nthuav dav. Thaum thov daim ntawv pov thawj, lawv tau xa ib nplooj ntawv hauv txoj cai. Qhov ntawd tsis muaj txiaj ntsig. Hauv qhov sib piv, qee cov tuam txhab European muaj tag nrho cov pob tab sis ntawm 40-50% tus nqi hwm. Koj yuav tsum txiav txim yog tias qhov project pob nyiaj siv thiab kev tuav pov hwm kev ruaj ntseg ua pov thawj rau nws. Qee zaum, qhov ua tau zoo tshaj plaws eco-phooj ywg expansion bolts yog cov uas koj muab qhov tseem ceeb rau ib lossis ob yam tseem ceeb-xws li cov txheej huv si thiab cov khoom siv hauv zos los txiav kev thauj mus los-tsis yog kev daws teeb meem zoo tag nrho.

Tsis txhob hnov ​​qab txog kev ntim khoom. Nws suab me me, tab sis kuv tau txais bolts xa hauv ntau lub hnab yas hauv lub thawv ntim styrofoam. Cov khoom yuav zoo heev, tab sis cov pov tseg negates ntau qhov txiaj ntsig. Tam sim no kuv qhia meej meej me me, ntim khoom rov ua dua tshiab hauv kev yuav khoom. Qee cov neeg siv khoom siv tau siv cov duab los qhia thiab cov ntawv sib cais. Nws yog ib qho me me uas qhia tau hais tias kev cog lus tiag tiag.

Tus nqi vs. Tus nqi: Lub Ntiaj Teb Kev Ua Lag Luam Tiag Tiag

Wb tham txog nyiaj txiag. Ntsuab fasteners yuav luag ib txwm raug nqi ntau dua. Lo lus nug yog: dab tsi yog tus nqi? Yog tias koj tab tom ua haujlwm ntawm lub tsev ntsuab uas muaj ntawv pov thawj, tus nqi yog nyob rau hauv kev ua raws thiab pab txhawb rau qhov kawg plaque ntawm phab ntsa. Rau ib txoj haujlwm ua lag luam tus qauv, tus nqi yuav nyob rau hauv qhov kev pheej hmoo txo ​​qis - zam kev lav ris yav tom ntej los ntawm kev txwv ib puag ncig ntawm cov khoom siv. Kuv tau txheeb xyuas tus nqi rau tus neeg siv khoom xyoo tas los: lub eco-phooj ywg expansion bolts ntxiv txog 15% rau cov khoom siv fastener. Tab sis thaum muab xam rau hauv tag nrho cov nqi project, nws yog tsawg dua 0.1%. Cov lus piav qhia thiab kev tswj hwm yav tom ntej-pov thawj muag nws.

Txawm li cas los xij, muaj kev lag luam cuav. Ib tug pheej yig "eco" ntsia liaj qhov rooj uas corrodes nyob rau hauv tsib lub xyoos yuav raug nqi koj kaum npaug ntau dua nyob rau hauv kev kho mob. Kuv kawm qhov no txoj kev nyuaj ntawm ib qhov project rwb thaiv tsev sab nrauv. Peb txuag tau $0.20 rau ib chav ntawm bolts nrog cov lus nug txog cov txheej txheem organic. Tsis pub dhau peb xyoos, xeb stains tshwm rau ntawm cladding. Kev tshawb nrhiav thiab kev hloov pauv tus nqi dwarfed thawj zaug txuag. Tam sim no, kuv xav them nyiaj rau lub bolt los ntawm ib lub koom haum paub zoo li Zitai, uas tsawg kawg muaj cov txheej txheem kev lag luam thiab cov txheej txheem tswj, thiab tom qab ntawd nws tus kheej txheeb xyuas nws cov lus thov ntsuab tshwj xeeb rau kuv daim ntawv thov.

Kev yuav khoom ntau yog koj tus phooj ywg. Chav tsev tus nqi sib txawv me me me thaum koj xaj lub thawv ntim puv. Qhov no yog qhov uas cuam tshuam ncaj qha nrog cov chaw tsim khoom hauv lub hub zoo li Yongnian ua rau kev nkag siab. Koj tuaj yeem sib sau ua ke ntau hom fastener rau hauv ib qho kev xa khoom, txo cov pa roj carbon monoxide per-unit los ntawm kev thauj mus los thiab muaj peev xwm sib tham txog cov ntsiab lus zoo dua rau cov khoom siv siab dua.

Cov kauj ruam tswv yim rau koj qhov kev yuav khoom tom ntej

Yog li, ua li cas koj thiaj yuav lawv? Ua ntej, sau cov lus qhia meej. Tsis txhob hais tias "eco-friendly." Qhia meej txog qhov yuav tsum tau muaj: "M10 expansion bolts, mechanical property class 8.8, with a geometric coating or certified organic coating (muab tus qauv), los ntawm cov hlau uas muaj yam tsawg kawg nkaus ntawm 50% recycled cov ntsiab lus, nrog rau EPD los yog zeb daim ntawv pov thawj qhia cov pa roj carbon hneev taw. Ntim yuav tsum yog 100% recyclable." Qhov no lim tawm 80% ntawm cov khoom tsis tsim nyog tam sim ntawd.

Qhov thib ob, thov cov qauv thiab sim lawv. Txhua tus neeg muag khoom muaj npe nrov yuav muab cov qauv. Ua koj tus kheej cov tshuaj tsuag ntsev yog tias ua tau, lossis xa lawv mus rau chav kuaj hauv zos. Txheeb xyuas qhov ua tau zoo ntawm kev siv tshuab. Kuv ib txwm sim cov txheej txheem teeb tsa-qee zaum cov txheej ntsuab cuam tshuam rau kev sib txhuam hauv lub tes tsho, ua rau kev teeb tsa tsis yooj yim. Qhov no tshwm sim nrog cov khoom Dutch; lub txheej yog slick heev, thiab lub bolt spun thaum zawm. Lawv yuav tsum tau hloov kho.

Thaum kawg, tsim kev sib raug zoo. Nrhiav qhov chaw txhim khu kev qha rau eco-phooj ywg expansion bolts tsis yog ib qho xwm txheej ib zaug. Thaum koj pom ib tus neeg muag khoom uas pob tshab thiab zoo ib yam, nrog lawv. Seb nws yog ib hom tshwj xeeb nyob sab Europe lossis cov neeg tsim khoom loj xws li HANDAN ZITAI FREWER RAUG UA MOV., Ltd. uas nquag txhim kho nws cov txheej txheem, txuas ntxiv txuag lub sijhawm thiab txo kev pheej hmoo ntawm cov haujlwm yav tom ntej. Lub hom phiaj tsis yog nrhiav cov khoom lag luam zoo meej, tab sis nrhiav tus khub txhim khu kev qha hauv cov saw hlau uas nkag siab txog kev sib tshuam ntawm kev ua tau zoo thiab kev ruaj khov, thiab txaus siab los ua pov thawj nws.
