Kukhazikika kwa gasket kwa zinki zamitundu? 

Tiyeni tidutse muyeso wa malonda. Munthu akafunsa za kulimba kwa a zinki wakuda yokutidwa gasket, nthawi zambiri amajambula mapeto abwino a buluu, achikasu, kapena akuda akugwira mpaka kalekale. Kuwona zenizeni: mtundu nthawi zambiri umakhala wofooka kwambiri. Si zida zamatsenga; ndi topcoat pamwamba pa maziko a zinc wosanjikiza, ndipo njira zake zolephereka ndizokhazikika ndipo, mwachidziwitso changa, nthawi zambiri samamvetsetseka pakugula.

Lingaliro Lolakwika Lachikulu: Mtundu Monga Magwiridwe

Ndawona zojambula zambiri zomwe zimangoyitanitsa buluu wa zinc gasket, poganiza kuti mtunduwo umatanthauza kukana kwa dzimbiri. Sizikutero. Maziko nthawi zonse amakhala zokutira zinki - nthawi zambiri zimakhala zokutira zosinthika zamtundu wa buluu pamwamba pake. Utoto umachokera ku utoto kapena mankhwala achiwiri oviikidwa mu chromate wosanjikiza. Chifukwa chake, kulimba kumagawika m'nkhondo ziwiri: chitetezo cha zinc cha nsembe, komanso kukana kwa mtundu wosanjikiza kuvala, UV, ndi kukhudzana ndi mankhwala.

Kumene kumakhala kovuta ndi kusonkhana. Wogwira ntchito yomangitsa bawuti, kapena gasket akusisita panyumba pakuyika, amatha kukanda mosavuta wosanjikiza wamitunduyo. Mwadzidzidzi, muli ndi malo onyezimira asiliva pomwe maziko a zinki amawonekera. Sikuli kulephera kwa chitetezo cha dzimbiri pano, koma chikuwoneka ngati chimodzi, ndipo zokometsera ndizofunikira pamagwiritsidwe omwe amayang'ana ogula. Ndikukumbukira gulu la zinki zakuda zokutidwa ndi flange zotchinga panja pomwe oyikapo amagwiritsa ntchito madalaivala amagetsi. Cholumikizira cha socket chidavala mphete kumapeto kwakuda pamipando yamutu ya bawuti isanawone mvula. Makasitomala sanasangalale ndi mawonekedwe ochita dzimbiri.

Zotsatira za mayeso opopera mchere zimafotokoza nkhani yolakwika. Chromate ya buluu yokhazikika pamwamba pa zinki imatha kugunda maola 96 mpaka dzimbiri loyera. Mitundu yamitundu, makamaka yakuda ngati drab yakuda kapena azitona, imatha kuwonetsa kufota kapena kuipitsidwa ngakhale kale, ngakhale zinc yomwe ili pansi ikugwirabe ntchito. Ngati dzina lanu limangoganizira za dzimbiri lofiira, muli bwino kwakanthawi. Koma ngati kukhulupirika kwa mtundu ndi gawo lazogulitsa - polemba kapena kuyika chizindikiro - mwalephera kale.

Zowona Zachilengedwe vs. Catalog Claims

Iwalani labu. Tiyeni tikambirane za malo otentha, onyowa a injini, kapena nyumba yakunja pafupi ndi gombe. Kuwonekera kwa UV ndikupha kwa utoto wachilengedwe. Buluu wonyezimira pa chochapira chomata pa bulaketi ya solar imatha kusintha mtundu wabuluu wamkaka, chokochoko munyengo imodzi. Chromate pansi ikugwira ntchito yake, koma mawonekedwe apita. Kuwonekera kwa mankhwala ndi chirombo china. Ndawonapo ma gaskets ofiira a zinki omwe amagwiritsidwa ntchito m'makina momwe kupopera kwamadzimadzi amadzimadzi nthawi zina kumasintha mtundu kukhala nyansi zopindika, zapinki. Madziwo sanawononge zinc, koma amasungunula utoto.

Apa ndipamene kusankha zinthu kumakulumani. A zinki wakuda yokutidwa gasket nthawi zambiri amasankhidwa ngati njira yotsika mtengo yosinthira chitsulo chosapanga dzimbiri kapena malata otentha opangira malo ocheperako. Koma zapakati ndizofunikira. Pamalo owuma, amkati momwe nthawi zambiri amazizindikiritsa? Kusankha bwino kwambiri. Pa chilichonse chokhala ndi condensation, kupalasa njinga pafupipafupi, kapena abrasion, muli pa nthawi yobwereka. Mtengo wosankha suyenera kuyamba pomwe tikufuna buluu, koma udzakhudza chiyani?

Tidayesa mayeso ofananiza zaka zingapo mmbuyo ndi magawo ochokera kumalo opangira zinthu ngati Yongnian ku Hebei. Tinali ndi zinki wamba, chromate ya buluu, ndi ma gaskets akuda okhala ndi okosijeni pamalo oyesera pamalo otetezedwa ndi theka. Chophimba chakudacho chinawonetsa kuzimiririka mkati mwa miyezi inayi. Mtundu wa buluu umakhala wabwinoko koma umapanga zoyera zoyera m'mphepete mwachangu. Zinc wamba amawoneka osasunthika koma sanapitirire ku dzimbiri lofiira mwachangu. Linali phunziro lomveka bwino: chowonjezera chamtundu nthawi zina chimatha kupanga ming'alu yaying'ono mosadziwa kapena kusiyanasiyana kwa chromate wosanjikiza komwe kumakhala malo oyambitsira dzimbiri.

Zosintha Zopanga: Zonse Zili mu Njira

Kukhalitsa sikungokhudza zakuthupi; zimamangirizidwa kwambiri pakuwongolera ndondomeko. Wodziwika bwino wogulitsa ngati Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd., kutengera malo ake mu gawo lalikulu kwambiri la China, nthawi zambiri amakhala ndi sikelo ndi njira yotsika. Koma ngakhale apo, satana ali mwatsatanetsatane. Masitepe ofunikira ndikukonzekera pamwamba musanaphike, makulidwe ndi kufanana kwa gawo la zinki, nthawi ndi kukhazikika mu bafa la chromate, komanso kutentha ndi kusindikiza kwa bafa la utoto.

Masitepe othamanga a chromate kapena utoto wosasindikizidwa bwino umabweretsa kulephera msanga. Ndalandira magulu omwe mtunduwo unachotsedwa ndi kukakamiza kwa chala. Ndilo vuto losindikiza pambuyo pa plating. Gawo lapansi ndilofunikanso. Gasket yosindikizidwa kuchokera kuchitsulo chotsika cha carbon motsutsana ndi chimodzi kuchokera ku alloy yapamwamba kwambiri idzakhala ndi mawonekedwe osiyana pamwamba pambuyo poyeretsa, zomwe zimakhudza plating adhesion. Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd. ndi opanga akuluakulu ofanana ali ndi mwayi wokhala ndi mitsinje yosasinthika yamafuta ndi mizere yodzipangira, zomwe zimachepetsa kusiyana kumeneku poyerekeza ndi masitolo ang'onoang'ono ogwira ntchito.

Langizo limodzi lothandiza lomwe ndimapereka nthawi zonse: funsani magawo odutsa kapena kuyesa matepi osavuta (pa ASTM D3359) pazitsanzo. Sizomwe zimapangidwira zomangira, koma zimakuuzani za kumamatira. Kanikizani chidutswa cha tepi yomatira yolimba pamtunda wachikuda, ndikung'amba. Ngati mtundu ubwera nawo, muli ndi vuto lolumikizana lomwe lingawonekere pamayendedwe kapena msonkhano.

Nthawi Yoyenera Kuigwiritsa Ntchito, ndi Nthawi Yoyenera Kuchokapo

Kotero, kodi zonse ziri zoipa? Ayi. Ndizokhudza ziyembekezo zoyendetsedwa. Pazigawo zamkati zomwe zimakhala zowuma, zoyendetsedwa bwino - lingalirani zoyika ma seva, mipando yaofesi, kapena mapanelo amakina amkati - zopaka utoto za zinki ndizosangalatsa kuzizindikiritsa zina komanso zimawoneka mwaukadaulo. Kukhalitsa kwake ndi kokwanira. Komanso, pamapulogalamu omwe amafunikira kutetezedwa kwa EMI/RFI, maziko a zinc amapereka ma conductivity, ndipo mtunduwo ukhoza kugwiritsidwa ntchito kutanthauza njira zoyambira kapena zolumikizira.

Kulephera kumabwera chifukwa chogwiritsa ntchito molakwika. Ndinalangiza kuti ndisamagwiritse ntchito makina opangira magalimoto kamodzi, koma gulu lojambula lidayikidwa pamtundu wakuda wa aesthetics. Anachiyesa m'chipinda ndipo chinapambana mayeso a corrosion waufupi. Dziko lenileni? Mchere wamsewu, kugwedera miyala, ndi chinyezi chosalekeza, zinapangitsa kuti zodzikongoletsera zisamalephereke pakapita chaka chimodzi. Tinayamba kugwiritsa ntchito malata opangira malata okhala ndi jasi lakuda, lomwe linali lokwera mtengo koma lokhalitsa. Phunziro: Fananizani zomwe zafotokozedwa ndi malo enieni, ovuta kwambiri, osati abwino.

Chinthu chinanso koma chofunikira: kuyanjana kwa galvanic. Chitsulo chachitsulo chopangidwa ndi zinc chotsutsana ndi nyumba ya aluminiyamu chimapanga banja la galvanic, koma zinki ili pafupi ndi aluminiyumu pamlingo wolemekezeka, choncho imakhala yaukali kuposa, kunena, gasket yachitsulo. Kupaka utoto kumawonjezera chotchinga chowonda, chosasunthika, chomwe chingathe kuchepetsa pang'ono galvanic current ngati ili bwino. Koma mukangomaliza, mumabwereranso ku zinc-aluminium contact. Ndichinthu chaching'ono, koma m'mipanda yamagetsi yamagetsi, ili pamndandanda.

Pambuyo pa Mbale: Njira Zina

Pamene chilengedwe chimafuna mtundu komanso kulimba kwambiri, muyenera kuyang'ana kupyola muyeso wamtundu wa electroplated zinc. Ma geometries ngati ma gaskets, okhala ndi m'mphepete mwake ndipo nthawi zambiri amakhala ndi masitampu ovuta, amakhala ovuta kuvala mofanana. Njira ina ndiyo kuyika makina ndi utoto, komwe kungapereke makulidwe abwino m'mbali. Chinanso ndi kupaka ufa, koma izi zimawonjezera makulidwe ndipo zimatha kukhudza kupsinjika mu pulogalamu ya gasket-ndizowonjezera zophimba kapena mabulaketi.

Kuti ukhale wolimba kwambiri, yankho nthawi zambiri ndikuchotsa ntchitoyo kuchokera kumtundu. Gwiritsani ntchito mapeto olimba kwambiri ngati Geomet? kapena Dacromet? pofuna kuteteza dzimbiri, kenaka yikani chigamba chamitundu, chochapira cha aluminiyamu cha anodized, kapena chizindikiro chopenti kuti mudziwe. Ndizokwera mtengo kwambiri, koma ndiukadaulo wowona mtima. Nthawi zina, njira yabwino kwambiri ndiyo kugwiritsa ntchito gasket yosalala, yapamwamba kwambiri ya zinc-nickel ndikuvomereza mtundu wosalowerera wa silver-gray. Kukana kwake kutsitsi kwa mchere kumatha kukhala maola 500+, kukulitsa chromate yamitundu iliyonse.

Pomaliza, kufotokoza a zinki wakuda yokutidwa gasket ndi kulinganiza kwa mtengo, kukongola, ndi kuwonekera kwenikweni. Ndiwomaliza bwino kwambiri mukagwiritsidwa ntchito ndi maso owoneka bwino. Musadalire chiwongola dzanja chambiri chamndandandawu pamtengo wamawonekedwe. Pezani zitsanzo, zikhazikitseni kumayendedwe anu enieni - chipinda cha chinyezi, bokosi la UV, zopukuta pang'ono zosungunulira - ndikuwona zomwe zimalephera poyamba. Maso anu ndi galasi lokulitsa losavuta lidzakuuzani zambiri kuposa pepala lililonse lachidziwitso kuchokera kwa ogulitsa, ngakhale lolimba lokhazikika pabwalo lalikulu ngati Handan Zitai. Kusasinthika kwawo kumakupatsirani poyambira bwino, koma kugwiritsa ntchito kwanu kumatanthauzira mzere womaliza.
