Malangizo othana ndi dzimbiri a nyundo

Nyundo ndi imodzi mwa zida zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale ndi m'nyumba zosiyanasiyana. Ngakhale kuti amapangidwa mosavuta, amapatsidwa ntchito zolemetsa, zomwe zimawapangitsa kuti azivala ndi kung'ambika. Chimodzi mwazinthu zazikulu zomwe nyundo zimakumana nazo, makamaka zopangidwa ndi chitsulo, ndi dzimbiri. Kuwonongeka sikungochepetsa kukongola kwa nyundo komanso kumachepetsa kulimba kwake komanso kugwira ntchito kwake. Pofuna kuthana ndi izi, opanga amagwiritsa ntchito njira zingapo zothana ndi dzimbiri kuti atalikitse moyo wa nyundo. Nkhaniyi ikuwunikira njira zina zotsutsana ndi dzimbiri zomwe zimagwiritsidwa ntchitokupanga nyundo.

1.Kusankha Zinthu

Kulimbana ndi dzimbiri kumayambira posankha zinthu. Nyundo zambiri zimapangidwa kuchokera kuzitsulo za carbon high, zomwe zimakhala zamphamvu koma zomwe zimachita dzimbiri. Kuti achepetse izi, opanga nthawi zambiri amasankha zitsulo za aloyi zomwe zimakhala ndi zinthu monga chromium, faifi tambala, ndi molybdenum. Zinthu izi zimathandizira kukana kwachitsulo ku dzimbiri. Chitsulo chosapanga dzimbiri, mwachitsanzo, ndi chisankho chodziwika bwino chifukwa cha zinthu zake zabwino zotsutsana ndi dzimbiri, ngakhale ndizokwera mtengo kuposa chitsulo chokhazikika cha carbon.

2.Zophimba Zoteteza

Imodzi mwa njira zodziwika bwino komanso zothandiza zopewera dzimbiri ndikugwiritsa ntchito zokutira zoteteza ku nyundo. Pali mitundu ingapo ya zokutira zomwe zingagwiritsidwe ntchito:

• Zinc Plating: Izi zimaphatikizapo kuvala nyundo ndi chitsulo chochepa kwambiri cha zinki, chomwe chimakhala ngati chopereka nsembe chomwe chimawononga m'malo mwa chitsulo pansi. Nyundo zokhala ndi zinc zimagonjetsedwa kwambiri ndi dzimbiri ndipo nthawi zambiri zimagwiritsidwa ntchito m'madera omwe chidacho chimakhudzidwa ndi chinyezi.
• Kupaka Powder: Kupaka ufa ndi njira yowuma yomaliza yomwe ufa (kawirikawiri ndi thermoplastic kapena thermoset polima) umagwiritsidwa ntchito pamwamba pa nyundo ndikuchiritsidwa pansi pa kutentha. Izi zimapanga mapeto olimba, olimba omwe amalimbana ndi dzimbiri ndi kuvala.
• Galvanization: Kuchita zimenezi kumaphatikizapo kuviika nyundo mu zinki yosungunuka kuti ikhale yokhuthala, yoteteza. Nyundo zamagalasi ndizothandiza kwambiri polimbana ndi dzimbiri ndipo ndizoyenera kugwiritsidwa ntchito panja kapena m'mafakitale.

3.Mafuta ndi Sera

Kwa nyundo zomwe zimafunika kusunga mawonekedwe achikhalidwe, makamaka omwe ali ndi matabwa, mafuta ndi sera amagwiritsidwa ntchito nthawi zambiri. Zinthuzi zimalowa pamwamba pazitsulo ndikupanga chotchinga chomwe chimatulutsa chinyezi komanso chimachepetsa ngozi ya dzimbiri. Mafuta a linseed, phula, ndi mafuta a tung amagwiritsidwa ntchito kwambiri pochiza izi. Ngakhale kuti sizolimba ngati zokutira, mankhwalawa ndi osavuta kugwiritsa ntchito ndipo angagwiritsidwenso ntchito nthawi ndi nthawi kuti ateteze chitetezo.

4.Kutentha Chithandizo

Njira zochizira kutentha, monga kuzimitsa ndi kutentha, sikuti zimangowonjezera mphamvu ndi kulimba kwa nyundo; atha kukhalanso ndi gawo lothandizira kuti zisawonongeke. Mwa kusintha microstructure yachitsulo, chithandizo cha kutentha chikhoza kuchepetsa chiwopsezo cha chitsulo kuti chiwonongeke. Komabe, njirayi nthawi zambiri imaphatikizidwa ndi njira zina, monga zokutira kapena kusankha zinthu, kuti mupeze zotsatira zabwino.

5.Zomangamanga Zazitsulo Zosapanga dzimbiri

Kwa ntchito zomwe kukana kwa dzimbiri ndizofunikira kwambiri, nyundo zachitsulo zosapanga dzimbiri ndi chisankho chabwino kwambiri. Chitsulo chosapanga dzimbiri chimakhala ndi kuchuluka kwa chromium, komwe kumapanga chitsulo chosapanga dzimbiri, chomwe chimalepheretsa dzimbiri kupanga. Ngakhale nyundo zachitsulo zosapanga dzimbiri zokwera mtengo zimafunikira kusamalidwa pang'ono ndipo ndi zabwino m'malo okhala ndi chinyezi chambiri kapena kukhudzidwa ndi zinthu zowononga.

6.Kusamalira Nthawi Zonse

Kupitilira njira zopangira, kukonza nthawi zonse kumagwira ntchito yofunika kwambiri poletsa dzimbiri la nyundo. Zochita zosavuta, monga kupukuta nyundo pambuyo poigwiritsa ntchito, kuisunga pamalo owuma, ndi kuyika mafuta nthawi ndi nthawi, imatha kukulitsa moyo wa chidacho. Ogwiritsanso ntchito ayang'ane ngati ali ndi dzimbiri kapena kutha ndikuthana nawo mwachangu kuti apewe kuwonongeka kwina.

Mapeto

Kuwonongeka ndizovuta kwambiri pakusunga moyo wautali komanso magwiridwe antchito a nyundo, koma ndi njira zoyenera, zitha kuyendetsedwa bwino. Kuchokera pa kusankha zinthu ndi zokutira zoteteza mpaka kukonza nthawi zonse, pali njira zingapo zomwe opanga ndi ogwiritsa ntchito angagwiritse ntchito kuteteza nyundo ku dzimbiri ndi dzimbiri. Pogwiritsa ntchito njira zotsutsana ndi dzimbirizi, mutha kuonetsetsa kuti nyundo yanu imakhalabe chida chodalirika komanso chokhazikika kwazaka zikubwerazi.
