Zovala zamtundu wa zinc-zokutidwa ndi flange: luso lokhazikika? 

Mukuwona 'zachikuda' ndi 'zokhazikika' palimodzi papepala, ndipo lingaliro lanu loyamba mwina ndikutsatsa. Ndinaganizanso choncho. Mu masewerowa, bawuti ndi bawuti-mpaka italephera pamalopo chifukwa zokutira zachita matuza, kapena kasitomala amadandaula kuti mitundu ya mutu wa hex imayamba kukhala pinki pakadutsa miyezi isanu ndi umodzi m'nkhokwe ya m'mphepete mwa nyanja. Funso lenileni siliri ngati plating zinki plating ndi luso, koma ngati ndi yolimba, yothandiza imene imasuntha singano pa zinyalala, kukonzanso, ndi moyo. Tiyeni tibwererenso zigawo.

Chikoka ndi Kukayikira Pompopompo

Mlanduwu ndi wolunjika: tengani muyezo zinc-yokutidwa ndi flange bawuti, yendetsani njira yosinthira chromate, ndipo pezani mitundu yosiyanasiyana - yabuluu, yachikasu, yakuda, utawaleza. Ndizodziwikiratu, kukana dzimbiri, nthawi zina ngakhale zokongoletsa pamapangidwe owonekera. Nthawi yokhazikika imakhazikika pa: moyo wautali umatanthauza kusintha kochepa, kugwiritsa ntchito zinthu zochepa. Koma apa pali vuto. Standard yellow zinc dichromate yakhalapo kwa zaka zambiri. Kuchitcha kuti 'chobiriwira' chifukwa chikhoza kukhala nthawi yayitali ngati plating siinasinthe kuchokera ku mizu yake yamankhwala.

Ndikukumbukira gulu lochokera kwa ogulitsa zaka zingapo mmbuyo, mabawuti okongola a yunifolomu abuluu opangira ma solar panel mounting structure. Kuyika kwamitundu kumapangidwa kuti kukhale kosavuta kukhazikitsa ma torque osiyanasiyana. Zowoneka bwino m'bokosi. Koma pulojekitiyi inali m'dera lomwe lili ndi chiwerengero chachikulu cha UV. M'miyezi 18 yokha, buluu pamitu ya flange inali itazimiririka kwambiri, pomwe maboti a zinc omwe anali pafupi ndi iwo amangowonetsa dzimbiri zoyera. Mtunduwu sunalephere mwadongosolo, koma cholinga chake - chizindikiritso chokhazikika - chidachitika. Kumeneko sikukhazikika; ndicho kupanga kutha kwa chinthucho.

Chifukwa chake, gawo lazatsopano liyenera kukhala lochulukirapo kuposa mtundu. Zimakhudza kukonzekera kwa gawo lapansi, chemistry yopangira, komanso pambuyo pa chithandizo. Njira zina zatsopano za trivalent chromate, zomwe sizowopsa kuposa hexavalent, zimatha kupereka kukhazikika kwamtundu. Koma ntchito zomatira ndi dzimbiri, moona mtima, zimatha kugunda kapena kuphonya. Mukugulitsa katundu wina wa 'kudzichiza' wa zopangira zinki zachikhalidwe za mtunduwo. Ndi kusagwirizana, osati kukweza koyera.

Kumene Kukhazikika Kumakhala Yeniyeni: Njira ndi Zopangira

Kwa ine, nkhani yowoneka bwino yokhazikika imatuluka mumayendedwe ndi zinthu. Apa ndi pomwe kampani imakonda Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd. zimabwera m'maganizo. Kutengera ku Yongnian, chomwe chili pakatikati pakupanga kofulumira ku China, kuchuluka kwawo kumalola kuti masitolo ang'onoang'ono azitha kuchita bwino: mizere yodzipatulira, yowongoleredwa. Mukapita kumalo ngati amenewo (tsamba lawo zitaifsteners.com imapereka chidziwitso cha momwe ntchitoyi ikuyendera), mukuwona kuthekera kochepetsera chilengedwe pa bolt.

Taganizirani izi. Ngati ntchito yopanga ku Europe ikufunika M12, M16, ndi M20 mabawuti a flange mu chikasu kwa msonkhano umodzi ndi wakuda kwa wina, sourcing iwo chisanadze amitundu kuchokera lalikulu, Integrated wopanga amachepetsa katundu angapo, angapo plating magulu, ndi akuchitira kugwirizana ndi ma CD. Malo a Zitai pafupi ndi njira zazikulu zoyendera simalo ogulitsa okha; amatanthauza katundu wophatikizidwa. Chidebe chimodzi chokhala ndi zomangira zomalizidwa kale, zokhala ndi mitundu yochokera kumalo opangira zinthu zazikulu zimakhala ndi mtengo wotsika wa kaboni kuposa kupeza mabawuti osavuta kuchokera pamalo amodzi ndikuwatumiza ku mbale zosiyanasiyana zakumaloko.

Mayesero enieni ali mu kasamalidwe ka thanki ya plating. Opanga ma voliyumu ambiri ali ndi chithunzithunzi chabwino chosungira chemistry, kuyeretsa bwino madzi oyipa, ndi kubwezeretsanso zitsulo. Ndiko kupindula kosasunthika komwe kulibe chochita ndi mtundu womwewo koma chilichonse chokhudzana ndi momwe bolt wachikuda amapangidwira. Kasitolo kakang'ono, kopanda ntchito bwino kotayira zinyalala za chromium ndikotsutsana ndi kukhazikika, mosasamala kanthu kuti mtundu womaliza umagulitsidwa 'wobiriwira' bwanji.

Njira Zolephera ndi Zowonera M'munda

Tiye tikambirane komwe mabawuti angakugwetseni. Hydrogen embrittlement ndi yachikale yokhala ndi bawuti yamphamvu kwambiri ya electroplated, koma njira yopangira utoto imawonjezera kupsinjika kwina. Ngati zokutira za chromate ndi zokhuthala kwambiri pofunafuna mtundu wowoneka bwino, zimatha kukhala zolimba komanso zong'ambika. Ndaziwona izi pansi pa maikulosikopu pamaboti ena ofiira omwe adalephera msanga pakugwiritsa ntchito makina onjenjemera. Ming'aluyo inakhala malo oyambitsira dzimbiri, kugonjetsa cholinga chonse.

Mutu wina wothandiza ndi kugwirizanitsa kwa galvanic. Mtundu wa chromate wamitundu umasintha mphamvu zamagetsi. Pamsonkhano wokhala ndi mabulaketi a aluminiyamu, bawuti wamba ya zinki ikhoza kukhala yabwino, koma yakuda yokhala ndi mawonekedwe osiyanasiyana imatha kufulumizitsa dzimbiri la aluminiyamuyo. Muyenera kudziwa ndondomeko yeniyeni ya chithandizo cha pambuyo pobisala, osati kungoganiza kuti ndi ‘zinki yokhala ndi utoto.’ Tinaphunzira izi movutikira pa ntchito ya kunja kwa kabati ya telecom. Maboti akuda amawoneka bwino, koma chassis ya aluminiyamu yowazungulira idawonetsa kuphulika kwakukulu mkati mwa zaka ziwiri. Maboti a zinc omveka pagawo lomwelo sanabweretse vuto lomwelo.

Ndiye pali torque kusasinthasintha. Bawuti yamtundu wa flange yokhala ndi wosanjikiza wosalala, wandiweyani wa chromate pamwamba pake imatha kukhala ndi mikangano yosiyana ndi zinki wamba. Ngati oyika sadziwa ndikugwiritsa ntchito mtengo womwewo wa torque, mutha kumangirira kapena, choyipitsitsa, kuthamangitsa kwambiri ndi kuvula ulusi. Zikumveka zazing'ono, koma pamzere wokhala ndi maulaliki zikwizikwi, ndizovuta zowongolera bwino. Njira yothetsera vutoli nthawi zambiri imakhala sera kapena mafuta, zomwe zimasintha maonekedwe ndipo zimatha kukopa dothi. Ndiko kutsagana kwa zigwirizano zazing'ono.

Nkhani Yofunika Kwambiri: Kugwiritsa Ntchito Bwino

Ndiye pali malo okoma? Mwamtheradi. Kumene achikuda zinc-yokutidwa zomangira zowala zili m'malo olamulidwa, osawoneka bwino pomwe phindu lawo lachiwiri limagwiritsidwa ntchito mokwanira. Chitsulo chamkati chamkati chokhala ndi mabawuti okhala ndi utoto wamitundu yosiyanasiyana kapena madongosolo oyendera. Magawo omanga opangidwa kale omwe ma bolt amawonekera komanso mtundu ndi gawo la kapangidwe kake, koma amatetezedwa ku nyengo yachindunji ndi UV.

Ndikukumbukira kugwiritsa ntchito bwino m'makina akuluakulu osungiramo katundu. Makasitomala adagwiritsa ntchito mabawuti a buluu polumikizira kugwedezeka kwamphamvu ndi achikasu pamitengo yokhazikika. Idapanga zowunikira pambuyo poyika komanso zosintha zamtsogolo mwachangu kwambiri. Chilengedwecho chinali chouma, m'nyumba, komanso kutentha kokhazikika. Maboti amenewo atha kupitilira makina ojambulira okha ndi kukonza zero. Munthawi imeneyi, mtunduwo umawonjezera mtengo weniweni, wokhazikika ndikuletsa zolakwika - ndiko kupanga kokhazikika.

Chofunikira ndikuwongolera zomwe kasitomala amayembekeza. Simuwagulitsa ngati m'malo mwachindunji ma bolts opaka malata otentha m'malo opangira madzi oyipa. Mumawayika ngati omaliza anzeru, owonjezera mtengo wamalo oyenera. Zofuna zawo zokhazikika zimakhala zamphamvu kwambiri zikamalepheretsa kusokonekera, kuchepetsa nthawi yoyika, ndikupangidwa munjira yabwino, yoyendetsedwa bwino yomwe imachepetsa zinyalala. Utoto wokha siwopanga zatsopano; kugwiritsa ntchito mozama kwa chigawo chomalizidwa ndi.

Kutsiliza: Chida, Osati Kusintha

Kukulunga izi, mabawuti amtundu wa zinc-plated flange ndi chinthu chosasinthika. Kuzitcha kuti 'zatsopano zokhazikika' ndikopanda malire. Iwo ndi a njira yokhazikika pokhapokha pazikhalidwe zenizeni: pamene plating ndondomeko ndi yoyera komanso yothandiza, pamene mapangidwe amtundu amakhala okhazikika komanso okhazikika kwa moyo wautumiki womwe ukufunidwa, ndipo mtunduwo umapereka phindu lowoneka, losatha lomwe limachepetsa zinyalala kapena zolakwika pamzere.

Makampaniwa akuyenera kupitilira zithunzi zonyezimira zam'ndandanda. Ntchito yeniyeni ili m'mapepala a data-maola oletsa dzimbiri muutsi wamchere, kukhazikika kwa UV, ma coefficients amakangana pakumaliza kwake. Opanga ngati Handan Zitai ali ndi kuthekera koyendetsa izi popereka mawonekedwe owonekera ndikusunthira kunjira zobiriwira ngati mulingo, osati mtengo.

Pomaliza, ndi chida china. Yothandiza ikagwiritsidwa ntchito ndi ukatswiri komanso kuwona bwino za malire ake. Zatsopano sizili mu bawuti yomwe mwagwira m'manja mwanu, koma pakudziwa nthawi yoti mugwiritse ntchito, komanso nthawi yoti muchoke. Chisankho chimenecho, chozikidwa pa zomwe zachitika komanso maphunziro ovuta, ndizomwe zimamanga mchitidwe wokhazikika.
