Maboti opangira malata: okhazikika pakumanga? 

Mumaona ‘zosonkhezera’ pa pepala lodziŵika bwino, ndipo lingaliro laposachedwa ndilo ‘losachita dzimbiri, lokhalitsa, labwino.’ Koma kodi imeneyo ndiyo nkhani yonse yokhazikika? Ndakhala ndikufufuza ndikutchula zomangira zamafakitale ndi zamalonda kwazaka zopitilira khumi, ndipo zokambirana zokhala ndi malata okhala ngati kusankha 'zobiriwira' nthawi zambiri zimakhala zosavuta. Sikuti zimangokhala zokutira zinc. Zili pafupi ndi moyo: mphamvu zopangira zokutira zimenezo, moyo wautali umene umapereka m'madera osiyanasiyana, ndi zomwe zimachitika ku bolt pambuyo pa moyo wa mapangidwewo. Timakonda kuphatikizira zokometsera zonse pamodzi, koma kuthirira kotentha-kuviika pambuyo pa kupanga ndi electroplating ndikosiyana kwambiri padziko lonse lapansi pakuchita komanso momwe chilengedwe chimakhalira. Tiyeni tifufuze izo.

Funso la Zinc: Zoposa Zovala Zokha

Hot-dip galvanizing (HDG) ndi heavyweight. Mumaviika bawuti yopangidwa m'bafa la zinki wosungunuka. Zotsatira zake ndi zokutira zokhuthala, nthawi zina zowawa pang'ono zomwe zimapanga mgwirizano wazitsulo. Pamalo onyowa kwambiri, okhala ndi mchere wambiri - ganizirani zomanga m'mphepete mwa nyanja kapena malo opangira madzi otayira - izi ndi zomwe mungapite. Itha kukankhira moyo wautumiki mpaka zaka 50+ ndikukonza pang'ono. Ndilo mtsutso wamphamvu wokhazikika: kuyika kumodzi, palibe kupentanso, palibe cholowa m'malo mwa mibadwo. Mphamvu yophatikizidwa imakhala yodzaza kutsogolo, koma imalipira.

Ndiye pali electro-galvanizing. Ndizochepa thupi, zonyezimira, zotsika mtengo. Zikuwoneka bwino m'bokosi. Koma polumikizana ndi nyengo yokhazikika, zimatha kukupatsani zaka 10-15 kuti dzimbiri liyambe kutuluka magazi. Ndaziwonapo pama projekiti otsika mtengo osungiramo katundu pomwe zomwe zidali zosadziwika bwino, ndikungoyitanitsa 'malata.' Wopanga makontrakitala adapeza njira yotsika mtengo, ndipo tidalamula kuti tilowe m'malo olumikizirana ovuta tisanasaine. Izi ndizosiyana ndi zokhazikika-ndizowonongeka zobisika ngati yankho.

Chiweruzo chenicheni chimabwera m'malo ovuta kwambiri. Kwa chimango chachitsulo chamkati m'nyengo youma, kodi HDG yachuluka? Mwina. Komano mumaganizira zotha kusintha m’tsogolo. Ngati nyumbayo ikasinthidwa, bawutiyo imatetezedwabe. Wothandizira yemwe ndagwira naye ntchito, Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd. kuchokera ku Yongnian, Hebei (malo opangira cholumikizira chachikulu), nthawi zambiri amawonetsa mfundoyi. Zolemba zawo zaukadaulo zikugogomezera kuti kufotokoza njira yoyenera yogwirira ntchito yomwe ikuyembekezeredwa ndi gawo loyamba lothandizira kugwiritsa ntchito bwino zinthu. Malo omwe ali pafupi ndi misewu yayikulu yoyendera ngati Beijing-Guangzhou Railway amatanthauza kuti amawona zinthu zambiri zotumizira kunja komwe mafotokozedwe amayenera kukhala omveka bwino.

Zowona Patsamba ndi Mtengo Wobisika

Nayi mutu wothandiza: hydrogen embrittlement. Maboti amphamvu kwambiri (Giredi 8.8 ndi pamwambapa) omwe amapangidwa ndi electroplated amatha kutenga kachilomboka. Kuyeretsedwa kwa asidi pakumangirira kumatha kuyambitsa haidrojeni muchitsulocho, kupangitsa kuti ikhale yolimba komanso kuti ikhale yolephereka kwambiri pamavuto. Ndi nkhani yodziwika, koma patsamba lofulumira, ndani amayang'ana ziphaso zamagulu a chithandizo cha hydrogen? Ndikukumbukira ntchito ya mlatho pomwe tinayenera kukana kutumizidwa kwa malata olimba kwambiri chifukwa ziphaso zoyeserera zinalibe zofunikira zowotcha ma hydrogen. Kuchedwetsako kumawononga ndalama zambiri kuposa mabawuti okha.

Wina nuance ndi kulolerana kwa ulusi. Chophimba chakuda cha HDG chingakhudze zoyenera. Nthawi zambiri mumayenera kugunda mtedza kapena kugwiritsa ntchito kupopera kwakukulu. Ngati izi sizikuwerengedwa pazithunzi zamapangidwe, mumapeza antchito pamalo omwe akuvutika kuti agwetse mabawuti kunyumba, zomwe zimatha kuwononga ulusi ndikusokoneza chitetezo cha dzimbiri. Ndikanthu kakang'ono komwe kamayambitsa kukangana kwakukulu - kwenikweni. Chisankho chokhazikika chimagwa ngati sichingayikidwe bwino.

Ndiye pali kusamvana. Simungangomenyetsa bolt muchitsulo chosamalidwa bwino. The galvanic reaction idzafulumizitsa dzimbiri wa membala wachitsulo. Ndaziwona izi pa fa?ade support system. Womangayo ankafuna mawonekedwe a dzimbiri a Corten zitsulo, koma tsatanetsatane wolumikizana adatchula zida zamagalasi. Mkati mwa zaka ziwiri, panali mikwingwirima yonyansa komanso maenje apakati. Tidasinthiratu zomangira zitsulo zosapanga dzimbiri pazigawo zenizenizo - kukonza kokwera mtengo koma kogwirizana.

Lifecycle ndi Masewera Omaliza

Chifukwa chake, timaganiza kuti bolt yopangidwa ndi malata imakhala moyo wanyumbayo. Koma kodi moyo umenewo ndi chiyani? Nyumba yosungiramo katundu ikhoza kugwetsedwa m'zaka 30 kuti imangidwenso. Pakadali pano bolt ikadali yowoneka bwino. Ndi zabwino? Tsopano ndi gawo la mtsinje wazitsulo zachitsulo. Chophimba cha zinki chidzatayika kwambiri mu ng'anjo yobwezeretsanso - chimasungunuka. Chitsulocho chimatha kubwezeretsedwanso bwino, koma zinc yapita. Kumeneko ndiko kutayika kwa zinthu zopanda malire.

Apa ndipamene kuyerekeza ndi zitsulo zosapanga dzimbiri kumakhala kosangalatsa. Stainless (A4-80, mwachitsanzo) ili ndi mawonekedwe apamwamba kwambiri a carbon popanga. Koma ngati zilola kusokoneza kosavuta ndikugwiritsanso ntchito bawuti yonse m'njira yatsopano, kawerengero kamasintha. Sitinakhalepobe ndi machitidwe okhazikika, koma m'mabwalo osinthika, ndi mkangano wamoyo. Ndi a bawuti ya malata kugwiritsa ntchito kamodzi kokha chifukwa nthawi zambiri kumadulidwa kapena kuwonongeka panthawi yogwetsedwa? Nthawi zambiri, inde.

Ndimayang'ana zovomerezeka zokhazikika monga LEED kapena BREEAM. Amapereka mbiri pazinthu zobwezerezedwanso. Chitsulo mu bawuti kanasonkhezereka nthawi zambiri amakhala mkulu zobwezerezedwa kagawo kakang'ono, amene ndi kuphatikiza. Koma nthawi zambiri amalanga kuopsa kwa zinc kuthamangitsidwa m'moyo wake (zochepa ngati zomangidwa bwino) kapena mphamvu yamphamvu ya ndondomeko yokhayokha. Dongosolo loyezera silimajambula chithunzi chonse, kotero kuweruza kwathu kwa akatswiri kuyenera kudzaza mipata.

Nkhani: Kulephera kwa Coastal Walkway

Chitsanzo konkire. Msewu wa m'mphepete mwa nyanja wa tauniyo unkagwiritsa ntchito malata kuti atetezere njanji zamatabwa m'malo a konkire. Zolembazo zinangonena kuti ‘dip-dip galvanized.’ Sizinatchule makulidwe a zokutira. Maboliti omwe adatuluka anali ocheperako. M'dera la splash zone, ndi kupopera mchere kosalekeza, zokutira zidatha pasanathe zaka zisanu ndi ziwiri. Mitu ya bolt idachita dzimbiri ndikukulitsidwa, ndikuphwanya nyumba za konkriti.

Kubwezera kunali kosokoneza. Tinkafunika kuchotsa mabawuti akale ndikuyika zatsopano, nthawi ino kutchula gulu lazovala zokulirapo (mwachitsanzo, mpaka ISO 1461, Class 4) ndipo zimafuna kukhudza malo aliwonse okhala ndi utoto wapamwamba wa zinki. Kodi tikuphunzirapo chiyani? Kukhazikika sizinthu zokha; ndiko kulondola kwatsatanetsatane. Kuitana kwachibadwa kwa 'malabati’ ndi pafupifupi wopanda pake. Mufunika ndondomeko, makulidwe, ndi ndondomeko yotetezera pambuyo poika.

Apa ndipamene opanga omwe ali ndi chithandizo cholimba chaukadaulo ali ofunikira. Kampani yomwe imangokugulitsirani bokosi la mabawuti sikukuthandizani. Imodzi yomwe imapereka matebulo a dzimbiri, maupangiri ogwiritsira ntchito, ndi deta yomveka bwino ya makulidwe okutikira m'malo osiyanasiyana. Ikusintha kugula kwazinthu kukhala kachitidwe kachitidwe.

Kusuntha Kupitilira Kusankha Kwa binary

Ndiye kodi mabawuti amalati ndi okhazikika? Ndi funso lolakwika. Funso loyenera ndilakuti: Kodi ndi kusankha kokhazikika, koyenera, komanso kogwiritsa ntchito bwino pa kulumikizana komweku m'malo omwe akuyembekezeka kwa moyo uno? Nthawi zina, yankho limakhala inde. Kwa nyumba yokhazikika yachitsulo m'malo amtawuni, ma bolts a HDG ndi njira yolimba, yotsimikiziridwa yomwe imachepetsa kukonzanso kwa moyo wonse.

Nthaŵi zina, yankho likhoza kukhala ‘ayi.’ Mwinamwake ndi bawuti yopangidwa ndi malata yoyeretsera, yoyendetsedwa mkati mwa mkati. Kapena mwinamwake, chifukwa cha zovuta, zolumikizira zosafikirika m'malo owononga kwambiri, zokutira ziwiri (zitsulo zosapanga dzimbiri zokhala ndi malata akunja) ndiye njira yokhazikika, ngakhale mtengo wake, chifukwa umatsimikizira kulowererapo kwa zero.

Zotengera zanga pambuyo pa zaka zonsezi? Musanyengedwe ndi chizindikiro chosavuta. Kumba mu ndondomeko. Tchulani ndi tsatanetsatane wowawa. Ganizirani za unyolo wonse, kuchokera ku mphamvu yopanga malo ngati Handan Zitai Fastener (mutha kuwona zolemba zawo patsamba lawo, https://www.zitaifasteners.com) kwa ogwira ntchito yogwetsa omwe pamapeto pake adzayenera kuthana nawo. Ndiko komwe kukhazikika kwenikweni pakumanga kumakhala-muzinthu zopanda pake, zosasangalatsa za bawuti yosavuta.
