Zovala zamtundu wakuda za zinc: zolimba? 

Ngati mukufunsa ngati ma bolts akuda a zinc-plated countersunk ndi olimba, yankho lalifupi ndiloti: zimatengera komwe mumazigwiritsa ntchito. Ndawonapo ma specs ambiri akuyitanitsa zinki wakuda ngati chogwira-zonse zolimbana ndi dzimbiri komanso kukongola, kuti magawowo alephere msanga m'malo olakwika. Chophimba chokha sichiri chofooka; ndikuyembekeza kuti ndi yankho lachilengedwe chonse.

Zomwe Zinc Wakuda Amatanthauza Pansi

M'malo mwake, zinki wakuda nthawi zambiri amatanthauza njira yopangira zinki yotsatiridwa ndi zokutira zakuda za chromate. Ichi si chotchinga chokhuthala, cholimba ngati phala la dip yotentha. Ndi gawo laling'ono lansembe. Chromate yakuda imapereka mtundu ndikuwonjezera kagawo kakang'ono ka corrosion resistance, koma ntchito yake yaikulu nthawi zambiri imakhala yokongola - kupereka yunifolomu, mapeto amdima omwe amawoneka ngati mafakitale kapena amachepetsa kuwala. Chitetezo chenicheni chimachokera ku zinc yomwe ili pansi, yomwe idzawonongeka kuti iteteze gawo lachitsulo. Chifukwa chake, kulimba apa ndikokhudza kuthekera kwa zinc kudzimana pang'onopang'ono.

Ndikukumbukira gulu la polojekiti zaka zapitazo, zomwe zimagwiritsidwa ntchito m'mipanda yamagetsi yamkati mu chipinda cha seva choyendetsedwa ndi nyengo. Iwo anachita bwino kwa zaka zambiri—popanda dzimbiri, mitu inakhala yoyera. Koma ndiwo malo abwino. Mukangoyambitsa chinyezi, mchere, kapena matenthedwe pafupipafupi, nkhaniyo imasintha. Kupaka kwakuda kumatha kubisa magawo oyamba a dzimbiri loyera (zinc oxide), lomwe ndi vuto. Simungathe kuwona kulephera kukubwera mpaka zitapita patsogolo.

Kapangidwe kamutu ka countersunk kumawonjezera gawo lina ku funso lokhazikika. Kuti mutsirize, nthawi zambiri mumagwiritsa ntchito makina kapena kupondereza mutu, zomwe zimatha kuonda kapena kuphwanya choyikapo m'mphepete. Ngati plating sikugwirizana pamenepo - ndipo nthawi zambiri zimakhala - ndiye poyambira dzimbiri lofiira. Ndayang'ana mbali zomwe dzimbiri lidayambira m'mphepete mwa mutu wa countersunk, malo olephera omwe amakhala okhudzana ndi geometry kuposa kupanga chemistry.

The Cross Recess: Chinthu Chobisika Chokhazikika

Aliyense amayang'ana pakupanga kwakunja, koma makina oyendetsa ndi ofunikira kuti azigwira ntchito molimba. Mutu wa Phillips (wopuma pamtanda), makamaka pa bolt ya countersunk, uli ndi mfundo zopanikizika. Pakuyika, ngati dalaivala sakhala bwino bwino kapena torque ndi yokwera, mutha kutuluka-kutsetsereka pang'ono ndikuchotsa chopumira. Bawuti yovulidwa sikhala yolimba ngakhale kuti kukana kwake kwa dzimbiri kuli kwabwino bwanji. Izi zimapangitsa mtundu wa mapangidwe a recess kukhala wofunikira. Mtanda wosapangidwa bwino, wosazama, kapena wapakati udzalephera pakuyika, kupangitsa bawuti kukhala yopanda ntchito.

Tinaphunzira izi movutikira kwambiri pamizere yolumikizirana pogwiritsa ntchito madalaivala ongodzipangira okha. Maboti akuda okhala ndi zinki, opangidwa pamtengo wotsika, anali ndi kuya kosagwirizana. Madalaivala anapitirizabe kutsetsereka, kuvula mitu, ndi kuimitsa chingwecho. Kukana dzimbiri kunalibe ntchito; mabawuti analephera pa siteji yoyendetsa. Zinatikakamiza kuyang'anira ogulitsa osati pa plating cert, koma pamutu wawo wozizira komanso kulekerera kwawo pakupuma. Kampani ngati Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd., yochokera ku malo opangira makina opangira magetsi ku China, nthawi zambiri imakhala ndi ukadaulo wopangira zida zopangira mawonekedwe osasinthika, omwe ndi ofunikira ngati kumaliza.

Ichi ndichifukwa chake pa ntchito iliyonse yovuta, ndingatchule galimoto yoyendetsa bwino kwambiri ngati Pozidriv kapena Torx ya mitu ya countersunk, koma sikuti nthawi zonse ndi njira yopangira cholowa kapena miyeso yeniyeni yomwe imayitanitsa mtanda wa Phillips.

Zachilengedwe Zapadziko Lonse: Kumene Amagwirira Ntchito ndi Kumene Sagwira

Tiyeni tione zenizeni. Pazinthu zamkati, zowuma - zamagetsi, mipando yamkati, zomangira zowuma m'nyumba zoyendetsedwa ndi nyengo - mabawuti awa ndi olimba kwambiri. Kumaliza kwakuda kumakhazikika, ndipo zinki imapereka chitetezo chokwanira ku chinyezi chamwadzidzidzi. Ndawagwiritsa ntchito kuchokera kumitundu ngati ITW Shakeproof kapena kuchotsedwa kwa ogulitsa ambiri ku Yongnian pantchito zotere popanda zovuta.

Malo otuwa amatetezedwa ndi ntchito zakunja - monga pansi pa nthiti, m'malo otsekera, kapena mkati mwagalimoto. Apa, mutha kupeza condensation, chinyezi cha apo ndi apo. Kukhalitsa kumakhala ntchito ya nthawi. Ndawawona zaka 2-3 zapitazo asanawonetse dzimbiri loyera, ndipo mwina 4-5 isanawonekere m'mphepete mwa dzimbiri. Ndi yolimba kwa chinthu chosamangika, chosinthika, koma osati kuyika kokhazikika.

Malo ovuta ndi ovuta ayi. Madera a m'mphepete mwa nyanja okhala ndi kupopera mchere, misewu yokhala ndi mchere wa de-icing, kapena malo okhala m'mafakitale omwe ali ndi chinyezi chambiri amadya kudzera muzitsulo zakuda zakuda m'miyezi. Chophimba chakuda chikhoza ngakhale kukhala ndi micropore, kufulumizitsa dzimbiri. Muzochitika izi, kuzitcha kuti zolimba ndi kulakwitsa. Mufunika zokutira zolemera monga plating, galvanizing yotentha, kapena kusinthana ndi chitsulo chosapanga dzimbiri.

Kusiyanasiyana kwa Ma Supplier ndi Vuto Labwino la Gulu

Kukhalitsa sikungokhudza zokhazikika; ndi za kupanga kosasintha. Kuchuluka kwa zinki wosanjikiza (kuyezedwa mu ma microns) ndi mtundu wa njira yosinthira chromate zimasiyana mosiyanasiyana pakati pa ogulitsa. Wopanga wodziwika bwino amatsatira miyezo ngati ASTM B633 pakupanga zinki, kutchula makulidwe ochepera (mwachitsanzo, ma microns 5 ogwiritsira ntchito malonda a SC2). Zambiri zotsika mtengo zimadumpha kuwongolera koyenera.

Mutha kuwona tsamba lawo, monga https://www.zitaifasteners.com, kuti awone ngati akufotokozera mwatsatanetsatane njira zawo ndi kuwongolera khalidwe. Wopanga yemwe amakhala pamalo opangira zinthu ngati Yongnian, wokhala ndi mwayi wopeza maunyolo ophatikizika, nthawi zambiri amakhala osasinthasintha. Kutchulidwa kwa Handan Zitai kukhala pagawo lalikulu kwambiri kukuwonetsa kuti ali ndi zomangamanga, komabe muyenera kutsimikizira zowongolera zawo. Ndakhala ndi ma bolts ofanana kuchokera ku maere awiri osiyana amachita mosiyana pamayeso ofanana a kupopera mchere.

Zotengera? Nthawi zonse funsani satifiketi yoyeserera ya gulu la plating, makamaka pama projekiti akunja. Musaganize kuti zinc wakuda amatanthauza chinthu chomwecho paliponse.

Kotero, Kodi Ndizokhazikika? Chigamulo Chothandiza

Ndi zovomerezeka inde. Zoyenera, zoyendetsedwa bwino, zinki wakuda-yokutidwa countersunk mtanda mabawuti perekani bwino kukana dzimbiri, kukongola, ndi mtengo. Kukhalitsa kwawo ndikovomerezeka. Koma si njira imodzi yokha yothetsera vutolo. Chophimbacho ndi chochepa thupi komanso chopereka nsembe; mtanda wopuma ukhoza kukhala wofooka ngati khalidwe ndi losauka.

Lamulo langa la chala chachikulu: zigwiritseni ntchito m'nyumba popanda lingaliro lachiwiri. Kuti mugwiritse ntchito panja, yembekezerani moyo wautumiki wa zaka 3-5, ndikukonzekera kuyendera kapena kusintha. Pantchito iliyonse yovuta kapena yovuta, tchulani kumaliza kapena zinthu zina zonse. Ndipo musamachitepo kanthu, perekani mtundu uliwonse wamtundu wamtengo wotsika mtengo - bawuti yovulidwa ndi bawuti yolephera, mosasamala kanthu za zokutira zake.

Pamapeto pake, kulimba ndi katundu wadongosolo, osati chinthu chokha. Zimatengera chilengedwe, njira yokhazikitsira, komanso kapangidwe kake kokhazikika kumbuyo kwa bawuti yomwe ili m'manja mwanu. Mapeto a zinc wakuda ndi mtundu umodzi wokha mu equation imeneyo.
