Cast aluminum base material

【China Aluminum Network】Choose what kind of solution will be used to brush the bottom layer, which will directly affect the quality of the coating. According to different substrates, select the appropriate solution. Special nickel has a very high bond strength to most of the metals on the substrate. It is commonly used on substrates such as steel, iron, copper, chromium, and stainless steel. For a substrate with a relatively high hardness, a low-stress solution should be selected. For materials such as cast aluminum and cast aluminum alloys, the materials are relatively loose and the porosity is relatively high. It is not appropriate to use a solution with strong acidity to brush the substrate, and the alkaline copper solution is selected for comparison. Suitable for. The specific process flow is as follows:

1) Electrolytic degreasing with 2# electrocleaning to remove oil.

2) Rinse with tap water.

3) activation with 1 # activation liquid, reverse, l0 ~ 15V, the amount of electricity is 0.7 ~ 1A h / dm2.

4) Rinse with water.

5) Basic copper bottoming. Positive. 6 ~ 8V, 1 ~ 2μm.

6) Rinse with tap water.

7) Brush the working layer.

Hook And Loop Backing Pad

Polishing Pads are use with Fibre Discs, PSA Discs and Discs,stone polishing pad,wool pad,etc.Backing pads are Widely used in grinding and polishing artificial stone, furniture and wood products, metals, cars and other items.Sanding disc backing pads are used beneath sanding discs to provide cushioning for contoured work and to provide the attachment surface for hook and loop or quick change discs. Pads may be solid or contain hole patterns to match sanding disc vacuum holes. Choose from soft to firm density depending on the degree of flexibility desired.
