Maboti amagetsi: okhazikika kuti agwiritse ntchito panja? 

Mukuwona funsoli likutuluka muzolemba ndi ma RFQ nthawi zonse. Yankho lalifupi, loyesa nthawi zambiri limakhala inde, lokutidwa ndi zinc, zili bwino. Koma ngati mwakhala mukuyang'ana zaka zamapangidwe, kapena zoyipitsitsa, mukukumana ndi kuyimba foni pamalumikizidwe olephera, mukudziwa kuti sikophweka. Yankho lenileni limakhala mwatsatanetsatane wa chilengedwe, mtundu wa plating, ndipo kunena zoona, zomwe kukhazikika kumatanthauza pa moyo wa polojekitiyi motsutsana ndi kungokhala mawu otsuka obiriwira. Tiyeni tifufuze izo.

Kukopa ndi Zowona Zagawo la Zinc

Electro-galvanizing ndi yokongola pazifukwa. Nthawi zambiri imakhala yotsika mtengo kuposa kuyika galvanizing yotentha ndipo imapereka kumaliza koyera, kosalala komwe kumawoneka mwaukhondo kunja kwa bokosi. Njirayi imaphatikizapo kuyika chingwe cha zinki pazitsulo zachitsulo. Chofunikira chomwe aliyense amaponya ndikuchikuta, chomwe nthawi zambiri chimafuna pafupifupi ma microns 5-8 a ma bawuti opangidwa ndi ma elekitirodi. Gawoli limapereka chitetezo chotchinga. Zimateteza chitsulo ku chinyezi ndi mpweya.

Koma nayi chinthu choyamba chothandiza: wosanjikizawo ndi woonda. Ndipo sichimangiriridwa ndi zitsulo monga kuviika kotentha. Ndawonapo magulu omwe zokutira zinali zosagwirizana, makamaka mu ulusi ndi pansi pamutu - malo omwe amapanikizika kwambiri. Wothandizira atha kunena kuti akugwirizana ndi ASTM B633, titi, SC Type 2, koma popanda kuwongolera machitidwe, mumapeza malo ofooka. Kampani ngati Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd., yochokera m'malo opangira zida zazikulu zaku China ku Yongnian, Hebei, ikhoza kukhala ndi ndalama zambiri, koma udindo uli pa wogula kuti atsimikizire kusasinthasintha kwa zinthu zakunja, osati kungoganiza.

Kotero, kwa munda okhetsedwa mu nyengo youma? Mwina zabwino kwa zaka. Kwa njanji ya m'mphepete mwa nyanja, chowonjezera mlatho kudera lamvula, kapena nyumba iliyonse yokhala ndi mikombero yowuma nthawi zonse? Chotchinga chowondacho, chomwe chingakhale chopanda ungwirocho chimakhala cholumikizira chofooka kwambiri. Chidziwitso chokhazikika chimayamba kuwonongeka pamene chinthucho chiyenera kusinthidwa m'zaka 5.

Njira Zowononga: Si Dzimbiri Basi

Anthu amaganiza panja ndipo amajambula dzimbiri lofanana. Chowonadi ndi chodziwika bwino komanso chankhanza. Zopha ziwiri zazikulu zomangira zomangira magetsi panja ndi dzimbiri loyera komanso dzimbiri lagalasi.

Dzimbiri loyera ndilo gawo loyera la ufa lomwe mumawona pa zinki. Zimachitika pamene zokutira zinki zimakhala zonyowa nthawi zonse ndipo sizingathe kupanga patina yake yotetezeka (zinki carbonate). M'malo otetezedwa omwe madzi amakhala - monga pakati pa malo otchingidwa kapena mabowo osakhetsedwa - zinki zimaonongeka mwachangu komanso mwachangu. Ndalekanitsa maulumikizidwe pakatha nyengo ziwiri kuti ndipeze zinki nthawi zambiri imasinthidwa kukhala ufa woyera, ndikusiya chitsulocho chilibe kanthu.

Galvanic corrosion ndi wakupha mwakachetechete. Gwirizanitsani bawuti yachitsulo yamagetsi yokhala ndi aluminiyamu, kapena choyipa kwambiri, mkuwa kapena chitsulo chosapanga dzimbiri, pamaso pa electrolyte (madzi amvula ndi okwanira), ndipo mumapanga batire. Zinc, pokhala anodic kwambiri, amawononga mofulumira kuteteza chitsulo chinacho. Ndimakumbukira ntchito ina ma bolts a electro-galvanized kuti muteteze chitsulo chamkuwa. The spec anafulumira. M'miyezi 18, mitu ya bawuti idawonongeka kwambiri, zomwe zidasokoneza kukonza. Kukonza kunali kodzaza, kokwera mtengo m'malo ndi insulated zitsulo zosapanga dzimbiri. Zosungirako zoyamba zidathetsedwa.

Kuphimba Kukhulupirika ndi Vuto la Ulusi

Malo opweteka enieni ndi ulusi. Njira yopangira ma electroplating imatha kusiya zokutira zolimba, zomangika kwambiri pazingwe za ulusi. Pakuyika, zokutira izi zimatha kugwedezeka kapena kuphulika. Tsopano muli ndi chowonjezera kupsinjika ndi zero dzimbiri zoteteza. Tinayamba kutchula zokutira zosintha za chromate (yellow iridite kapena buluu wowoneka bwino) pamaboliti opangidwa ndi ma electro-galvanized kuti titetezeke pang'ono, koma ngakhale chimenecho ndi gawo losanjikiza pazinki, osati kukonza kuwonongeka kwamakina. Kugwetsa bawuti kumatha kukwapula ndi nati kapena dzenje loponyedwa.

Nkhani Yofunika Kwambiri: Pulojekiti Yotsika mtengo ya Fence

Chitsanzo konkire kuyambira zaka zingapo mmbuyo. Paki ina yamatawuni idafuna kuyika mipanda yachitsulo yotalika mamita mazanamazana. Bajeti inali yolimba. Chomwecho chinafuna mabawuti amalatisi. Kontrakitala, pofuna kupeza ndalama zotsika mtengo, adapeza mabawuti otsika mtengo amagetsi, mwina kuchokera kwa wopanga zinthu zambiri. Iwo ankawoneka chonyezimira pa kuika.

Fast patsogolo zaka zitatu, m'dera ndi zolimbitsa mafakitale m'mlengalenga ndi msewu mchere kutsitsi mu dzinja. Mafelemu a mpanda anali abwino (wothira-kuviika malata), koma mutu uliwonse wa bawuti ndi nati zinali zonyansa za dzimbiri lofiira ndi kutumphuka koyera. Kudzimbirika kunali koipa kwambiri kotero kuti mtedza wina unagwidwa, zomwe zimafuna kuti ma angle grinders achotsedwe panthawi yobwezera. Mbali yokhazikika inali zero-kuwonongeka kwakukulu kwa ntchito ndi zipangizo zokonzekera msanga. Zikadakhala kuti zomangira za hot-dip galvanized (HDG) kuti zifanane ndi nsalu ya mpanda, kapenanso bwinoko, zokometsera zamakina kuti zokutira ulusi wosasinthasintha, moyo ukanatha kuwirikiza kawiri kapena katatu.

Apa ndipamene tsatanetsatane wa zopezera ndizofunikira. Malo omwe amapanga, monga Zitai Fastener kukhala moyandikana ndi mayendedwe akuluakulu (Beijing-Guangzhou Railway, Expressway), amalankhula za kayendetsedwe kabwino, osati kukwanira kwazinthu. Muyenera kukumba mumayendedwe awo enieni opangira ma electro-galvanizing akunja, ngati atapereka ngati mzere wodzipatulira wazinthu.

Kodi Ma Electro-Galvanized Angagwire Ntchito Panja Liti?

Si zonse zoipa ndi zachisoni. Pali ma niches. Chigamulochi chimabwera chifukwa cha kuuma kwa chilengedwe komanso kupezeka kwa chisamaliro.

Pazinthu zamkati kapena zotetezedwa bwino (monga mkati mwa denga lolowera mpweya wotetezedwa ku nyengo yachindunji), magetsi opangira magetsi ndi okwanira. Kukana kwake kwa dzimbiri ndikokwanira motsutsana ndi chinyezi cha mumlengalenga chokha.

Chitsanzo china ndi cha nyumba zosakhalitsa zomwe zakonzedwa kuti ziwonongeke ndikugwiritsanso ntchito pakanthawi kochepa, tinene zaka 1-3. Kutsirizitsa kosalala kumapangitsa kugwira ntchito mosavuta. Komanso, ngati chomangiracho chidzapakidwa utoto kapena kupachikidwa ngati gawo la msonkhano, wosanjikiza wa electro-galvanized amapereka fungulo labwino, loyera la dongosolo la utoto ndikuwonjezera chitetezo chowonjezera. Koma dongosolo la penti liyenera kukhala losasunthika ndikugwiritsidwa ntchito moyenera - zokopa panthawi yoyika kapena ntchito zimapanga malo opangira dzimbiri.

Chigamulo: Sustainable is a Function of Lifecycle

Choncho, kubwerera ku funso lofunika. Kodi mabawuti opangidwa ndi ma elekitirodi ndi okhazikika kuti agwiritsidwe ntchito panja? Kutenga kwanga, polimbana ndi chisankho ichi mobwerezabwereza, ndi ichi: akhoza kukhala, koma pokhapokha pamikhalidwe yopapatiza kwambiri yomwe nthawi zambiri sichimakumana ndi zofunikira zakunja.

Kukhazikika kwenikweni kumatanthauza kusankha zinthu zoyenera pa moyo wautumiki woyembekezeredwa ndi chilengedwe kuti tipewe kulephera msanga ndikusintha. Pazinthu zambiri zomwe zimafunikira panja - m'mphepete mwa nyanja, chinyezi chambiri, mafakitale, kutulutsa mchere wamchere, kapena zomangira zokhazikika - zomangira zama electro-galvanized ndizomwe zimakhala pachiwopsezo chachikulu. Zosankha zokhazikika ndi malata otentha, malata, kapena zitsulo zosapanga dzimbiri (monga 304 kapena 316, kutengera kukhudzana ndi kloridi). Mtengo wawo wapamwamba kwambiri umachepetsedwa pa moyo wautali, wopanda kukonza.

Lingaliro lomaliza: tchulani nthawi zonse molondola. Osangolemba malata. Tchulani ndondomekoyi (mwachitsanzo, ASTM A153 ya dip yotentha), makulidwe okutira, ndi chithandizo chilichonse chowonjezera. Ndipo pamalumikizidwe ovuta, lingalirani zakuyang'anira pamalopo gulu loyamba la zomangira. Mayeso opopera mchere mwachangu pa ASTM B117, ngakhale atangoyang'ana maola 96, amatha kuwulula zambiri zamtundu wa ogulitsa motsutsana ndi zomwe amalemba. Zimapulumutsa dziko lakumutu pambuyo pake, kutembenuza zonena zokhazikika kukhala zenizeni, zenizeni.
