Chero simbi yakafumurwa kumhepo kwenguva yakareba inoita kuti oxidize nekufamba kwenguva. Mushure memakore eruzivo rwakaratidzwa, Fasteners Engineering yakagadzira uye yakagadzira nhevedzano yekurapa inokwanisa kugadzirisa dambudziko reoxidation pamabhaudhi. Pazasi tinonyora maitiro akasiyana ekugadzira anoshandiswa uye akagadziridzwa pahwaro hwezvinodiwa nevatengi vedu.

Seimwe yeakakosha fasteners, screws anowanzo shandisa akasiyana epamusoro ekurapa maitiro kusangana nezvinodiwa nevatengi. Tariro kuti ruzivo runotevera ruchakubatsira iwe.

1. Zinc plating.

Galvanizing inogona kukamurwa kuita inotonhora galvanizing, mechanical galvanizing uye inopisa galvanizing, iyo inopisa galvanizing ndiyo inonyanya kufarirwa. Kupisa galvanizing, inozivikanwawo sehot-dip galvanizing, ndeyekunyudza mativi esimbi anobviswa ngura muzinc solution inosvika 500 ℃. Nenzira iyi, pamusoro pe workpiece yakabatanidzwa ne zinc layer, iyo inoshandisa chinangwa chekudzivirira-corrosion. Zvakanakira zvekupisa dip galvanizing ndezvizvi:

• Simba rinopesana nekuora.
• Zvirinani kunamatira uye kuoma kweiyo galvanized layer.
• Huwandu hwezinc hwakakura, uye ukobvu hwezinc layer ine gumi nembiri dzenguva dzekutonhora kwe galvanizing.
• Zvakachipa uye zvakanyanya kushamwaridzana kwezvakatipoteredza.

2.Surface phosphating.

Surface phosphating ndeye isingadhure yepamusoro kurapwa inoshandiswa seprimer isati yapenda.

• Chinangwa chikuru ndechekupa dziviriro kune simbi uye kudzivirira simbi kubva pakusvibiswa kusvika pamwero wakati.
• Kuvandudza kusungirirwa kwepende yefirimu.
• Deredza friction uye lubrication panguva yesimbi inotonhora kushanda.

3.Dacromet rudzi rutsva rwe-anti-corrosion coating, iyo ndiyo yakanakisa tekinoroji yekutsiva yechinyakare electro-galvanizing uye inopisa-dip galvanizing iyo ine yakakomba kusvibiswa kwezvakatipoteredza. Zvayakanakira ndezvizvi:

• Superior corrosion resistance: iyo ngura yekudzivirira mhedzisiro ndeye 7-10 nguva yakakwira kupfuura yechinyakare galvanizing.
• Iko hakuna hydrogen embrittlement phenomenon, iyo yakanyatsokodzera kupfekedzwa kwezvikamu zvakamanikidzwa.
• Kupisa kupisa kwepamusoro, tembiricha yekupisa inogona kusvika pamusoro pe300 ℃.
• Kubata kwakanaka uye kudzokorora kuita
• Hapana mvura yakaraswa uye gasi remarara richagadzirwa panguva yekugadzira.

4. Gonye

Ruspert imhando yejasi yakatangwa yekuvaka screws, iyo ine hushamwari yakagadziriswa yakagadziriswa mushure meDacromet. Kuenzaniswa neDacromet, zvakanakira ruspert ndezvizvi:

• Yakasimba corrosion kuramba, inogona kumira munyu yekupfapfaidza bvunzo kwemaawa 500-1500
• Harder coating
• Zvirinani kupedzwa kwepamusoro uye kunamatira
• Mamwe mavara aripo

DD Fasteners ine makore makumi maviri ekugadzirisa kugadzirwa uye ruzivo rwekutengesa.

Kana iwe uine chero screw zvinodiwa, ndapota taura nesu, isu tichakushandira nemoyo wese.
