Question 10

Cellulose and acrylic paint application

Answer 10

The surface of the metal is cleaned and decrease to ensure that the primer has a surface to grip to. The primer is followed by an undercoat in a similar colour to the topcoat.

Paints can be applied by brush or spray.

Question 11

Electroplating application

Answer 11

The product and donor material are placed in a container with an electrolyte solution. As the direct current is applied the product attracts the donor metal and the product is electroplated.

Question 12

Polymer dip coating application

Answer 12

The metal product is heated to 230°C. The hot product is dipped into a tank of fine polymer powder which has air flowing through it to provide an even coating to the product. The retained heat from the product melts the polymer powder over the product which is an air code to allow the coaching to set evenly.

Question 13

Metal dip coating application

Answer 13

Metals are coated by dipping the product into a tank of molten plating metal. The metals must be clean and decreased.

Question 14

Powder coating application

Answer 14

The product to be coted is negatively statically charged. Do set polymer resin is positively charged and is sprayed through an air gun. The use of charge results in a strong traction between the powder and the product. The product is them baked in an oven which melts the powder over the product give an even coating.

Question 15

Metal varnishing application

Answer 15

The metal is polished to shine and any surface grease removed. The varnish is then applied by either spray or fine brush.

Question 16

Sealants application

Answer 16

Applied with a cloth or machine pad to produce a film that is allowed to cure for up to 15 minutes. It is then buffed with a cloth to shine.

Question 17

Preservatives application

Answer 17

Applied by wiping with a cloth spray or immersion of the product.

Question 18

Anodising application

Answer 18

The electric current passes through the sulphuric acid electrolyte solution from the part be treated to the negative cathode.

As the current flows from the part be treated, which is the anode to the cord, the aluminium oxide layer buildup on the treated part producing an anodised finished.

it can then be finished with a varnished to provide further protection against surface scratches
