Dikirim ing 22-06-2016 Lapisan serpihan seng minangka jinis lapisan tahan karat sing anyar, wis akeh digunakake, proses lapisan serpihan seng utamane yaiku bahan dasar, degreasing, derusting, coating, preheating, curing, cooling.
1. Degreasing: lumahing workpiece kudu degreased, umume wis telung cara: organik solvent degreasing, banyu basis degreasing agen, suhu dhuwur carbonization degreasing.Whether degreasing sak tenane efektif, bakal langsung mengaruhi adhesion saka nutupi.
2. Derusting lan deburring: workpiece karo teyeng utawa Burr sing strictly dilarang nutupi langsung, kudu ngliwati proses derusting lan deburring, proses iki wis luwih nggunakake cara mechanical, supaya asam kanggo nyegah embrittlement hidrogen.
3. Coating: workpiece sawise degreasing lan derusting kudu dipping, nyemprotake utawa brushing asap.
4. Pre-heating: workpiece karo seng flake coating Paint ing lumahing kudu wis dadi panas 10-15 menit asap ing suhu 120 + 20 ℃, kanggo nggawe lapisan Cairan penguapan banyu.
5. Curing: workpieces sawise pra-panas kudu ngobati ing 300 ℃ suhu dhuwur, ngruwat wektu 20-40 menit, uga bisa jumbuh mundhakaken suhu kanggo shorten ngruwat wektu.
6. Cooling: Workpieces sawise ngruwat kudu kebak digawe adhem dening cooling sistem kanggo reprocessing utawa rampung pengawasan barang.
