Maboti amagetsi: okhazikika pamakampani? 

Mumamva 'electro-galvanized' ndikuganiza 'kuteteza dzimbiri,' mwinanso 'wobiriwira' chifukwa ndi zinki, sichoncho? Ndiko kumene kukambirana kawirikawiri kumayambira, ndipo kawirikawiri kumathera. Koma funsani aliyense amene anafunikira kutchula zomangira zapanja zomwe zimawona mchere wamsewu, kapena chida chosungiramo chinyezi, ndipo nkhani yeniyeni imayamba. Kodi electro-galvanizing ndi chisankho chokhazikika pamafakitale, kapena tikungokakamira njira yodziwika bwino, yotsika mtengo kwinaku tikunyalanyaza mtengo wake? Ndakhala zaka zambiri ndikufufuza ndi kuyesa zinthu izi, ndipo yankho siliri papepala. Zili m'mizere ya dzimbiri pamtengo pakatha miyezi 18, mtengo wosinthira mabawuti chikwi pa makina onyamula katundu, ndikusintha mwakachetechete ogulitsa ena akupanga.

Zokopa ndi Zowona Zaposachedwa

Tinene momveka bwino: mabawuti opangidwa ndi electro-galvanized ali ndi malo awo. Njirayi ndi yowongoka - zinc plating kudzera mu electrodeposition. Ndiwotsika mtengo kwa kuthamanga kwamphamvu kwambiri. Kwa mkati, ntchito zowuma, kapena pamene zokutira zimakhala ndi mawonekedwe ofanana ndi chitetezo chochepa, zimagwira ntchito. Ndayitanitsa matani aiwo m'malo ngati Chigawo cha Yongnian ku Hebei, komwe kuli malo opangira ma fastener. Kampani yomwe ilipo, Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd., ndi maziko awo kumanja kwa mayendedwe akuluakulu (onani malo awo pa https://www.zitaifasteners.com ngati mukufuna kukula kwake), mutha kutembenuza izi ndi katundu wa chidebe. Kusavuta kwake sikungatsutse.

Koma chowonadi choyamba ndi makulidwe. Chophimba chopangidwa ndi electro-galvanized chikhoza kukhala 5-8 microns. Ndizo zoonda. Mutha kuvula ndi chala ngati mutayesa. Yerekezerani izi ndi galvanizing yotentha, komwe mukuyang'ana ma microns 50+, ndipo kusiyana kwa kukhazikika sikuli mzere-ndikofotokozera. Ndidaphunzira izi koyambirira, ndikutchula mabawuti a electro-galvanized M12 othandizira ma tray a chingwe pafakitale yonyowa pang'ono. M’zaka ziŵiri, tinali ndi dzimbiri loyera ndi zina zofiira zofiira pamitsitsi ya ulusi. Osati tsoka, koma mutu wokonza zomwe sitinapange bajeti.

Funso lokhazikika limayambira pomwepa: ngati chinthu chikalephera mwachangu ndipo chikufunika kusinthidwa posachedwa, zosungira zoyambira (zinc zochepa, mphamvu zochepa pakuyika) zimakanidwa mwachangu ndi kupanga, kutumiza, ndikuyika m'malo mwake. Mukugulitsa kaboni wocheperako wam'mwamba kuti mukhale ndi moyo wapamwamba kwambiri. Ndiko kuwerengera komwe sitipanga kawirikawiri pansi pa sitolo tikamayitanitsa.

Mtengo Wobisika: Kuwonongeka kwa Magwiridwe Antchito ndi Malire a Njira

Kumene ma electro-galvanizing amawonetsa malire ake ali m'malo aliwonse okhala ndi ma chloride, ma acid, kapena chinyezi chokhazikika. Zovala za zinc ndi nsembe, zomwe ndi zabwino, koma ndizochepa thupi zomwe zimachepa mofulumira. Ndikukumbukira pulojekiti yokhudzana ndi malumikizidwe a ma bawuti otchinga m'mphepete mwa nyanja. Tidagwiritsa ntchito zomangira zamagetsi za ASTM F1941, poganiza kuti zikhala bwino. Kupopera mcherewo kunkafulumizitsa dzimbiri, ndipo zinkiyo inali itapita m’mawanga m’miyezi ingapo, zomwe zinachititsa kuti chitsulocho chizimbirire. Kulephera kwachikale, kopewedwa.

Nkhani ina yomwe nthawi zambiri imanyalanyazidwa ndi hydrogen embrittlement. Njira yopangira ma electroplating imatha kuyambitsa haidrojeni kukhala chitsulo champhamvu kwambiri (Giredi 8.8 ndi pamwambapa), ndikupangitsa kuti ikhale yolimba komanso yosavuta kusweka mwadzidzidzi. Ichi sichiwopsezo chongoyerekeza. Ndawonapo ma bolts akugwedezeka panthawi ya torque-mmwamba, ndipo pamene kuphika kungathe kuthetsa haidrojeni, ndi sitepe yowonjezera yomwe imawonjezera mtengo ndi zovuta, ndipo sizimachitidwa nthawi zonse modalirika pa zotsika mtengo, zothamanga kwambiri. Chifukwa chake, mutha kugulitsa chitetezo cha dzimbiri pachiwopsezo cha umphumphu wamakina. Osati zambiri.

Ndiye pali nkhani ya kuyanika kufanana. Pazigawo zovuta monga ma bolts okhala ndi ulusi wozama, electrodeposition ikhoza kukhala yosagwirizana, kusiya muzu wa ulusi-wovuta kwambiri - ndi chitetezo chochepa. Ndilo malire a ndondomeko. Mutha kufotokozera zokutira zosinthika za chromate (buluu, chikasu, okusayidi wakuda) kuti muwonjezere, koma izi zimawonjezera mankhwala ochulukira pamndandanda. Mwadzidzidzi, plating yosavuta ya zinc si yosavuta kapena yoyera.

Kuyeza Green mu Zinc

Othandizira amanena kuti zinki ndi chinthu chachilengedwe, chomwe chikhoza kubwezeretsedwanso. Zoona. Koma njira ya electroplating yokha si yabwino. Madzi otayira m'mabafa obirira amakhala ndi ayoni a zinc, ma acid, ndi mankhwala ena. Kuchiza koyenera sikungakambirane kuti kutsatidwe ndi chilengedwe. M'magawo omwe ali ndi zinthu zambiri zopanga, monga Yongnian, kasamalidwe kazachilengedwe ka mazana ambiri ogulitsa plating ndiye vuto lenileni lokhazikika. Wopereka ngati Zitai Fastener ogwira ntchito pamlingo woyenera ali ndi malo apakati, othandizira amakono, koma si chitsimikizo chapadziko lonse lapansi. Kukhazikika kwa bolt kumangiriridwa mwachindunji ndi kukhazikika kwa malo ogulitsira.

Recyclability ndi kuphatikiza. Pamapeto pa moyo, chitsulocho chimagwiritsidwanso ntchito, ndipo wosanjikiza wa zinc wochepa thupi umatayika mu sungunuka, koma siwoipitsidwa. Komabe, phindu lakumapetoli ndilofunika kwambiri pazigawo zazitsulo zolemera za dip-dip. Kwa bawuti yaying'ono, mphamvu yobwezeretsanso mphamvu yachitsulo imayang'anira; chopereka cha zokutira ndi pang'ono. Cholinga chachikulu cha kukhazikika ndikukulitsa moyo wautumiki kuti muchedwetse chochitikacho kwa nthawi yayitali momwe mungathere.

Ndiye, kodi ndi yobiriwira kuposa, titi, bawuti yachitsulo chosapanga dzimbiri? Kwa malo otsika kwambiri, mwinamwake, pamaziko a mphamvu yopangira mphamvu (kupanga zitsulo zosapanga dzimbiri ndizowonjezera mphamvu). Koma m'malo owononga, bawuti imodzi yokha ya 304 kapena 316 yomwe imatha zaka 30 imakhala yokhazikika kuposa kusinthira mabawuti amagetsi zaka 5-10 zilizonse, ngakhale pobwezeretsanso. Masamu amasintha mukaganizira za moyo wonse wokhazikitsidwa.

Kusintha Kothandiza ndi Supplier Evolution

Makampani sali okhazikika. Zokambirana zikuyenda kuchokera pagulu kupita ku zomatira. Ndikuwona mafunso ochulukirapo opangira malata amakina (omwe amapewa kuyika kwa haidrojeni) kapena zokutira zopyapyala za polima zamakanema zomwe zimapereka kukana kwa dzimbiri kuposa ma electro-zinki pa makulidwe ofanana. Othandizira abwino kwambiri akusintha.

Mukalankhula ndi wogulitsa zaukadaulo kwa wopanga wokhazikika - ndipo ndakhala ndi macheza awa ndi anthu omwe amagwira ntchito ngati ija. Handan Zitai Fastener- sakungokankhira manambala amndandanda panonso. Amafunsa za chilengedwe: Kodi ndi m'nyumba? Pali mankhwala aliwonse? M'mphepete mwa nyanja? Angakutsogolereni kutali ndi ma electro-galvanized kupita ku zokutira za zinc-flake kapena njira yothira yotentha ngati chofunikira chanu ndi moyo wautali kuposa mtengo wotsika kwambiri. Ndicho chizindikiro cha kukhwima. Malo awo pamalo opangira zinthu amatanthawuza kuti amawona zolephera zonse ndi zopambana zikuyenda, ndikuti mayankho amalowa m'malingaliro awo.

Tidayesa kusintha kasitomala kukhala bolt yamtundu wa Dacromet (zinc-flake) kuchokera pamagetsi okhazikika amagetsi kuti agwiritse ntchito zida zaulimi. Mtengo unali wa 15-20% kuposa. Zaka ziwiri, mabawuti opangidwa ndi ma electro-galvanized pagulu lakale anali kuwonetsa dzimbiri pamitu ya hex, pomwe zatsopano zimawoneka zatsopano. Wogulayo anasiya kudandaula za mtengo. Kusankha kosasunthika kumawapulumutsa ndalama pakapita nthawi popewa kutsika kwa zinthu zina. Ndiwo umboni weniweni wa dziko.

Ndiye, Chigamulo Ndi Chiyani?

Kuitana ma bolts opangidwa ndi ma elekitirodi kukhala okhazikika kumakampani ndikofuna zambiri. Iwo ndi a zokhazikika kusankha. Kwa malo olamuliridwa, abwino omwe kukana kwa dzimbiri kwa nthawi yayitali sikuli kofunikira, amapereka ndalama zoyenera, magwiridwe antchito, ndi kugwiritsa ntchito zinthu. Kukhazikika kwawo kumakulitsidwa pamene zofooka zawo zenizeni zikulemekezedwa.

Komabe, pakugwiritsa ntchito m'mafakitale - zomwe nthawi zambiri zimatanthawuza kusinthasintha kwa chinyezi, kuyanika, kuipitsidwa, kapena kukhudzana ndi mankhwala mwangozi - kudalira zomangira zama electro-galvanized nthawi zambiri ndichuma chabodza komanso njira yosakhazikika. Imakankhira zolemetsa zachilengedwe ndi zotsika mtengo mtsogolo chifukwa chakulephera msanga.

Njira yokhazikika ndikufananiza ukadaulo wakuphimba mwamphamvu ndi malo ogwirira ntchito, ngakhale zitakhala zokwera mtengo kwambiri. Zimatanthawuza kufunsa mafunso ovuta kwa wogulitsa wanu, kuyang'ana kupyola mtengo wa kilogalamu, ndikuganiziranso mtengo wonse wa umwini. Makampaniwa ali ndi zosankha zabwinoko tsopano. Kukhazikika sikungokhudza zakuthupi; ndi za kupanga chisankho choyenera kotero kuti mankhwalawa safunikira kupangidwanso posachedwa. Ndipo nthawi zina, bolt yokhazikika kwambiri ndi yomwe simuyenera kuganiza zoyisintha.
