Apa perawatan lumahing sisipan Utas?

Perawatan permukaan insert thread nuduhake proses mbentuk lapisan panutup ing permukaan benda kerja kanthi cara tartamtu.. Sawise perawatan permukaan, sisipan benang bisa nampilake tampilan sing luwih apik, lan resistance karat saka insert thread dhewe uga bakal apik. Tujuan sing luwih penting yaiku nggawe benang kasebut dipasang anti karat, supaya bisa nambah linuwih lan adaptasi saka fastener. Electroplating, hot-dip galvanizing, lan plating mechanical minangka telung cara sing paling umum digunakake kanggo perawatan lumahing sisipan Utas.

1. Electroplating
Electroplating saka sisipan benang nuduhake nyemplungake bagean sisipan benang sing kudu dilapisi menyang larutan banyu tartamtu.. The aqueous solution will contain some deposited metal compounds. In this way, after the current passes through the aqueous solution, the metal substances in the solution precipitate and adhere to the thread inserts. on the immersed portion of the firmware. The electroplating of fasteners generally includes zinc plating, copper, nickel, chromium, copper-nickel alloy, lsp. Sometimes boiling black (blue), phosphating, lsp. are also included.

2. Hot dip galvanizing
Hot-dip galvanizing of fasteners is to immerse carbon steel thread inserts into a molten zinc plating bath with a temperature of about 510°C, so that the iron-zinc alloy on the surface of the fastener will be converted into passivated zinc. To obtain surface treatment effect (similar to hot dip aluminum plating)

3. Mechanical plating
Plating mekanik saka sisipan benang nuduhake nggunakake cara fisik lan kimia tartamtu kanggo nyebabake permukaan sisipan benang kanthi bubuk logam sing dilapisi., supaya logam dilapisi mbentuk lapisan ing permukaan fastener liwat welding kadhemen kanggo entuk efek perawatan lumahing. Plating mekanik saka fasteners utamané cocok kanggo spare parts kayata sekrup, kacang lan washers.

Kanggo ngadili kualitas perawatan permukaan insert thread, iku utamané kanggo mriksa apa kemampuan anti-karat saka insert thread wis èfèktif tambah lan apa Tambah meets syarat samesthine. Cara inspeksi yaiku simulasi lingkungan kerja produk, nyetel kahanan test, lan nindakake tes karat ing. Langkah kapindho yaiku mriksa tampilan.
