A hot-dip aluminum-silicon-zinc steel plate production process, a pre-treatment method for aluminum-silicon alloy plating, a double-coordinating agent acidic zinc dip solution and its preparation method, a method for plating a ternary alloy layer on aluminum-silicon alloy, and a method for making its products, electrostatic spraying Anti-rust oil and its production method. Method for making a hot-dip aluminum plating tank. Method for making an environmentally friendly hot-dip aluminum plating flux.

The galvanized wire must be equipped with pre-treatment with electrolytic degreasing, and undergo comprehensive processes such as alkali brushing, water brushing, and rinsing to remove impurities such as oil, rust, iron filings, and dust on the surface of the steel plate to a maximum extent. Question: What are the requirements for the smelting process of hot-dip aluminum-zinc-silicon alloy? The process requirements for hot-dip aluminum-zinc-silicon alloy smelting are much higher than those of galvanizing.

This document specifies the terms and definitions, technical requirements, evaluation index system and evaluation methods for the product standard evaluation of hot-dip aluminum-silicon alloy coated steel plates and steel belt runners. This document is applicable to home appliances and automobiles with a thickness of 0.30mm ~ 00mm "Leader in corporate standards for continuous hot-dip aluminum-silicon alloy coated steel plates and steel strip products."

Hot-dip plating alloys can be used for surface coating of continuous hot-dip plated steel plates, surface protection of metal pipes, high-speed guardrails, street light poles, automobile bodies, solar brackets, ships and other products, and have a wide range of applications. In particular, the new ZnAlMg alloy has very excellent corrosion resistance and can greatly increase the service life of related products.

The results show that point defects generated on the surface of aluminum-silicon coated steel plates are mainly divided into four categories. The components of type I point defects are mainly AlSi oxide and zinc oxide, which are caused by aluminum slag and adhesion to the coating surface; type II point defects The reason is that aluminum slag or foreign matter is pressed into the surface of the coating; Type III point defects are composed of AlFeSi oxide, AlSi oxide and WC and CoC compounds.
