Chitsulo chilichonse chomwe chimawululidwa ndi mpweya kwa nthawi yayitali chimakonda kukhala oxidize pakapita nthawi. Pambuyo pazaka zambiri zotsimikiziridwa, Fasteners Engineering yapanga ndi kupanga mankhwala angapo omwe amatha kuthetsa vuto la okosijeni pamaboti. Pansipa tikulemba njira zosiyanasiyana zopangira zomwe zimagwiritsidwa ntchito ndikusinthidwa malinga ndi zosowa za makasitomala athu.

Monga chimodzi mwazomangira zofunika, zomangira nthawi zambiri zimagwiritsa ntchito njira zosiyanasiyana zochizira kuti zikwaniritse zosowa za makasitomala. Tikukhulupirira kuti mfundo zotsatirazi zidzakuthandizani.

1. Zinc plating.

Galvanizing akhoza kugawidwa mu ozizira galvanizing, makina galvanizing ndi otentha galvanizing, amene otentha galvanizing ndi otchuka kwambiri. Hot galvanizing, yomwe imadziwikanso kuti hot-dip galvanizing, ndikumiza zitsulo zochotsa dzimbiri mu njira ya zinki pafupifupi 500 ℃. Mwa njira iyi, pamwamba pa workpiece imamangiriridwa ndi zinc wosanjikiza, zomwe zimagwira ntchito yotsutsa-kutu. Ubwino wa dip galvanizing ndi motere:

• Mphamvu zotsutsana ndi dzimbiri.
• Bwino kumamatira ndi kuuma kwa kanasonkhezereka wosanjikiza.
• Kuchuluka kwa nthaka ndi kwakukulu, ndipo makulidwe a nthaka wosanjikiza ndi kangapo kozizira kozizira.
• Zotsika mtengo komanso zokonda zachilengedwe.

2. Phosphating pamwamba.

Surface phosphating ndi mankhwala otsika mtengo kwambiri omwe amagwiritsidwa ntchito ngati choyambira asanapente.

• Cholinga chachikulu ndicho kupereka chitetezo ku zitsulo ndikuletsa zitsulo kuti zisawonongeke pamlingo wina.
• Kupititsa patsogolo kumamatira kwa filimu ya utoto.
• Chepetsani kukangana ndi mafuta pakugwira ntchito kuzizira kwachitsulo.

3.Dacromet ndi mtundu watsopano wa anti-corrosion №, yomwe ndi teknoloji yabwino kwambiri yosinthira ma electro-galvanizing ndi otentha-dip galvanizing omwe ali ndi kuwonongeka kwakukulu kwa chilengedwe. Ubwino wake ndi motere:

• Kukana kwamphamvu kwa dzimbiri: mphamvu yolimbana ndi dzimbiri ndiyokwera nthawi 7-10 kuposa kupangira malata.
• Palibe chodabwitsa cha hydrogen embrittlement, chomwe chili choyenera kwambiri pakupaka magawo opsinjika.
• High kutentha kukana, kutentha kukana kutentha akhoza kufika pamwamba 300 ℃.
• Kumamatira kwabwino komanso kuyambiranso ntchito
• Palibe madzi otayira komanso gasi wotayidwa adzapangidwa panthawi yopanga.

4. Mbozi

Ruspert ndi mtundu wa zokutira zomwe zidakhazikitsidwa pazomangira, zokutira zoteteza zachilengedwe zomwe zidapangidwa pambuyo pa Dacromet. Poyerekeza ndi Dacromet, ubwino wa ruspert ndi awa:

• Kukana kwamphamvu kwa dzimbiri, kumatha kupirira mayeso opopera mchere kwa maola 500-1500
• Chophimba cholimba
• Kumaliza bwino pamwamba ndi kumamatira
• Mitundu yambiri ilipo

DD Fasteners ali ndi zaka 20 zakupanga mwachangu komanso zogulitsa.

Ngati muli ndi zomangira zofunika, chonde tilankhule nafe, tidzakutumikirani ndi mtima wonse.
