CN104941887A - Fan painting technique - Google Patents

Abstract

The invention discloses a fan painting technique which comprises the following specific steps that a grinding machine is used for grinding off rust, burrs and welding slag on the outer surface of a fan, a spray gun is used for evenly spraying a layer of fluorocarbon paint used as an undercoat on the surface of the fan, the spray gun is used for evenly spraying a layer of epoxy mica iron paint used as an intermediate coat on the surface of the fan, the spray gun is used for evenly spraying a layer of acrylic paint used as a finishing coat on the surface of the fan, and checking and packaging are carried out. The fan painting technique has the advantage that paint is not prone to being removed.

Description

A kind of blower fan enamelling process

Technical field

The present invention relates to a kind of blower fan enamelling process, be applied to the production and processing field of blower fan.

Background technology

In the process of manufacture of blower fan, need to spray paint to the surface of blower fan, but, existing blower fan lacquer spraying technique is fairly simple, one deck paint is only applied on the surface of blower fan, but PASS can be caused so little, easily occur falling the situation of paint, and alkali resistance, the corrosion resistance of individual layer paint are also poor.

Summary of the invention

For solving the defect of prior art, the invention discloses the reasonable blower fan enamelling process of a kind of paint difficult drop-off, alkali resistance and corrosion resistance.

The invention discloses a kind of blower fan enamelling process, concrete steps are as follows:

Step one: after blower fan integral solder completes, uses abrasive machine to polish off the iron rust on blower fan outer surface, burr, welding slag;

Step 2: be transported in painting booth by the blower fan of having polished, uses the surface uniform of spray gun to blower fan to spray one deck F-C paint as priming paint, then places 30-50 minute;

Step 3: use the surface uniform of spray gun to blower fan to spray one deck epoxy micaceous iron paint as intermediate coat, then place 1-2 hour;

Step 4: use the surface uniform of spray gun to blower fan to spray one deck acrylic paint as finish paint, then place 2-3 hour;

Step 5: test package.

By applying one deck F-C paint as priming paint on blower fan surface; and then apply one deck epoxy micaceous iron paint as intermediate coat; the adhesive force of such acrylic paint finish paint just significantly strengthens; be not easy the situation occurring falling paint; thus provide good protection to blower fan surface; and owing to coating three layers of paint, therefore alkali resistance and corrosion resistance relatively good.
