Hot-kuviika kanasonkhezereka mankhwala bolts durability? 

Tiyeni tidutse muyeso wa malonda. Wina akafunsa za kulimba kwa ma bawuti amadzi otentha, nthawi zambiri amakhala akuyembekezera yankho lamuyaya. Chowonadi ndi messier, ndipo funso lenileni silimangokhudza zokutira zinki, koma zomwe zimachitika pamawonekedwe pomwe bolt, zomatira, ndi chilengedwe zimakumana.

Lingaliro Lolakwika la Chotchinga

Zambiri zimangolemba makulidwe a malata, titi, ma microns 85 mbali iliyonse. Ichi ndi chiyambi chabwino, koma ndi nambala chabe. Kumene ndikuwona mapulojekiti akugwedezeka ndikuganiza kuti makulidwe ndi chishango chofanana, chosasunthika. Si. Ganizirani za geometry ya bolt - mizu ya ulusi, utali wapansi pamutu, mabala ophwanyika. Kutuluka kwa zinki pakuviika kumatha kukhala kocheperako m'malo awa. Ngati dzenje lanu laling'ono lili lolimba kapena muli ndi makina othamangira omwe amachotsa ulusiwo poyikapo, mwangopanga tsamba laling'ono loyambitsa dzimbiri, mosasamala kanthu za dzina. Wotchi yokhazikika imayamba kugunda mwachangu pomwepo.

Ndiye pali zomatira za nangula wamankhwala wokha. Sikuti ma resin onse amapangidwa mofanana. Ma vinyl ester kapena epoxy formulations atha kukhala ndi pH kapena amakhala ndi ma amines omwe, m'malo onyowa nthawi zonse, angakhudze zinc wosanjikiza kwazaka zambiri. Sindinawonepo kulephera kowopsa kuchokera ku izi zokha, koma m'malo okhala ndi chloride-monga garaja yoimikapo magalimoto pomwe mchere wa de-icing umagwiritsidwa ntchito - kuphatikiza ndikokupha. Mcherewu umapanga electrolyte yonyowa, yoyendetsa bwino yomwe imachokera ku njira ya konkire ya pore kupita ku bolt. Zinc imadzipereka yokha, yomwe ndi ntchito yake, koma mlingowo ukufulumira.

Mutu weniweni womwe ndidakumana nawo unali pa coastal boardwalk retrofit. Mabotiwo adanenedwa kuti ndi HDG, ndipo zomatirazo zinali zapamwamba kwambiri. Komabe, mkati mwa zaka 7, tinali ndi dzimbiri ndikulira pamalo a konkriti mozungulira chochapira. Kusanthula pambuyo pochotsa (ntchito yosokonekera, yokwera mtengo) idawonetsa kuti zinki zidali bwino pa shank, koma zidapita pamizere ingapo yoyambirira yomwe idayikidwa mu konkire. Njira yolephera? Chinyezi chodzaza ndi mchere chimadutsa m'ming'alu yaing'ono ya konkriti, ndikukhazikika pamawonekedwe omatira ku ulusi. Zinkiyo inkateteza boliti yachitsulo, koma inachita dzimbiri pomwe inafunikira kwambiri. Phunziro silinali kuti HDG ndiyoyipa, koma kuti kulimba kwake kumadalira dongosolo.

Chomangira Chomangira & Chobisika Chobisika

Ichi ndiye crux yomwe ma catalogs samalankhula. Mphamvu ya bolt ya mankhwala imachokera ku mgwirizano pakati pa utomoni ndi chitsulo. Malo osalala, atsopano a zinki ndi abwino kuti ateteze dzimbiri, koma kodi ndi malo abwino kwambiri omangira zomatira? Ena opanga zomatira angakuuzeni kuti muchotse zokutira za zinki pamalo omangira kuti mugwire bwino ntchito. Izi zikuwoneka ngati zosagwirizana, sichoncho? Mukuchotsa chitetezo kuti mupeze mphamvu. Ndiko kusinthanitsa komwe kumafunikira chigamulo chaumisiri potengera gulu lachidziwitso.

Ndikukumbukira supplier, Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd. (mutha kuwona kusiyanasiyana kwawo https://www.zitaifasteners.com), kamodzi kukambirana mfundo imeneyi. Kutengera ku Yongnian, malo olumikizirana kwambiri ku Hebei, amawona zinthu zambiri zopangira ndikusintha. Iwo adanenanso kuti chifukwa cha ma bawuti awo otenthetsera amakasitomala opita kumalo ankhanza, nthawi zina amalimbikitsa kuyatsa kokulirapo, kolamuliridwa ndi kusesa pambuyo pa malata kuti apititse patsogolo mawonekedwe ake omangika, osasokoneza chitetezo chambiri cha dzimbiri. Ndi gawo laling'ono lomwe limawonjezera mtengo, kotero kuti silingalowe muzolemba zilizonse, koma limalankhula ndi kumvetsetsa kwapadziko lapansi kwazomwe zikuchitika padziko lapansi.

Mpata wobisika ndi wakupha wina wokhazikika wokhazikika. Ngati dzenjelo silikutsukidwa bwino-kwenikweni, moyenera, ndi burashi ndi mpweya-mumapeza fumbi pakati pa zomatira ndi konkire. Kapena, ngati chomatiracho sichinabayidwe bwino, kusiya malo ozungulira bolt. Mpata umenewo umakhala nkhokwe ya chinyezi. Ngakhale ndi wandiweyani otentha-kuviika kanasonkhezereka kuyanika, madzi otsekeka okhala ndi okosijeni angayambitse dzimbiri, kuukira komweko komanso mwaukali. Ndadula mabawuti omwe amawoneka bwino kunja koma anali ndi zoboola kwambiri m'matumba obisika awa.

Kuchita Kwanthawi Yaitali vs. Kuyesa Kwambiri

Zotsatira za mayeso opopera mchere - ngati dzimbiri lofiira la maola 1000 - ndi chida chabwino chofananira koma cholosera bwino za kukhazikika kwapadziko lapansi kwazaka zambiri. Mayesowa ndi osalekeza komanso ankhanza. Malo enieni amakhala ndi mikombero yonyowa-youma. Panthawi youma, zinki zowonongeka zimatha kupanga patina yoteteza, kuchepetsa kuukira kwina. Kulimba kwake nthawi zambiri kumakhala kwabwinoko kuposa momwe mayeso opopera mchere amasonyezera, malinga ngati pali nthawi zowumitsa izi.

Komabe, m'malo onyowa kosatha, okwera njinga zamoto, monga pansi pa mlatho, nkhaniyo imasintha. Kukhazikika, kusowa kwa madzi, ndi kusinthasintha kwa kutentha komwe kumapangitsa kuti bolt ipume kumatulutsa chinyezi mkati ndi kunja. Apa ndipamene ndawona kuti kuchepa kwa zinc ndikokulirapo. Tinayang'anira malo ena olowera makwerero pamadamu. The otentha-kuviika kanasonkhezereka mankhwala mabawuti adawonetsa zodziwikiratu, ngakhale kutayika kwa zinki pazaka 15, kulola dongosolo lokonzekera lokonzekera. Chinsinsi chake chinali kuti chilengedwe chinali chovuta koma chokhazikika, osati chapakatikati.

Mayeso ofulumira amaphonyanso kuwonongeka kwamakina. Kugwedezeka, kusinthika pang'ono, kukulitsa kutentha kwa bolt yachitsulo motsutsana ndi konkriti. Kayendedwe kakang'ono kameneka kamatha kuthyola zigawo zachitsulo zachitsulo, ndikuwonetsetsa chitsulo chatsopano. Izi zikachitika, chiwopsezo cha zinc chimakhala chokhazikika komanso champhamvu pakusweka kwake.

Pamene Kukwanira Kwabwino Kulibe - Mtengo Wofotokozera Mochulukira

Kuthamanga kwa kulimba kumatha kubweretsa mainjiniya opitilira muyeso. Ndawonapo ma specs akuyitanitsa ma bolts a mankhwala a HDG m'malo owuma, mkati, oyendetsedwa ndi nyengo. Mukulipira chitetezo cha dzimbiri chomwe sichidzatsegulidwa. Kulimba kwake ndi kosatha, koma momwemonso kungakhale boti yachitsulo ya kaboni pamalopo. Zinc sichimawonjezera phindu pamenepo.

Mosiyana ndi zimenezi, m'malo owononga kwambiri mafakitale (zomera za mankhwala, mphero zamapepala), HDG yokhazikika ikhoza kukhala chisankho cholakwika kuyambira pachiyambi. Denga lake lolimba ndilotsika kwambiri. Apa, mungafunike kachitidwe ka duplex: dip-dip galvanized kuphatikiza malaya apamwamba a epoxy powder. Zinc imapereka chitetezo cha cathodic ngati zokutira zawonongeka (kuphatikiza kwakukulu), ndipo epoxy imapereka chotchinga chokulirapo, cholimba kwambiri. Ndizokwera mtengo kwambiri, koma zokhudzana ndi kupanga moyo wautumiki wofunikira. Kuyesera kupanga bawuti wamba wa HDG kukhala zaka 50 m'malo amenewo ndi njira yolepherera msanga.

Apa ndipamene mtengo wa opanga odziwa bwino umafika. Kampani ngati Handan Zitai Fastener, yomwe ili m'chigawo chachikulu kwambiri cha China chopanga magawo omwe ali ndi maulalo ake, si fakitale chabe. Amakonza madongosolo osawerengeka amadera osiyanasiyana. Kukambitsirana kwaukadaulo ndi iwo kungakupangitseni kutalikirana ndi kugwiritsa ntchito mankhwala amkati ku projekiti ya m'mphepete mwamadzi, kapena kugwiritsa ntchito mopitilira muyeso pamayendedwe apanyanja posungira shelufu. Kawonedwe kawo, kozikidwa pa kuchuluka kwake komanso kusiyanasiyana, kumawonjezera gawo lothandiza pazambiri zokhazikika.

Chigamulo: Ndi Dongosolo, Osati Chigawo

Kotero, kubwerera ku funso loyamba. Kukhazikika kwa a otentha-kuviika kanasonkhezereka mankhwala bawuti palibe nambala imodzi. Ndi zotsatira za: khalidwe ndi kugwirizana kwa galvanizing ( ❖ kuyanika makulidwe, kuphimba), ngakhale ndi bwino unsembe wa zomatira, kukonzekera gawo lapansi konkire, ndi kukhudzana mwachindunji chilengedwe (chlorides, m'zinthu chinyezi, kutentha).

Kuchokera pa zomwe ndaziwona pamasamba ndi m'ma post-mortems, bolt yokhala ndi malata bwino (yomwe imayang'aniridwa ndi kuphimba ulusi), yophatikizidwa ndi zomatira zoyenera zomwe zimayikidwa bwino m'malo ocheperako, zidzapereka moyo wautumiki wazaka 30+ mosavuta. Zolephera nthawi zambiri zimabwereranso ku kunyengerera mu umodzi mwa maulalo amtunduwu-nthawi zambiri kuyika, nthawi zina kusagwirizana kwatsatanetsatane.

Chifukwa chake, musangoyang'ana satifiketi ya bolt. Ganizilani za msonkhano wonse. Tchulani njira zoyeretsera mabowo. Lingalirani za chilengedwe moyenera. Ndipo mvetsetsani kuti nthaka ikudzipereka yokha kuti iteteze chitsulo; kukhazikika kwake kumatanthauzidwa ndi kuchuluka kwa zomwe mukulolera kuti ziwonongeke. Konzani ndikulongosola ndikugwiritsa ntchito m'malingaliro, ndipo mupeza zomwe mukulipira.
