Surface Preparation and Adhesive Application

Vibriso The surface must be prepared to provide the desired corrosion resistance and rubber adhesion strength. These processes vary according to material properties. It definitely changes the adhesion performance between surface-treated material and non-treated material.

1 • Pre degreasing (Metal products; Steel, aluminum, bronze, brass, castings)

2 • Sandblasting (Metal products; Steel, aluminum, bronze, brass, castings)

It is made with special materials that look like sand but are actually different from the sand we know, which are specially manufactured for this job, called Grit, and have different usage places. In short, we can say that sand is thrown onto the part with the help of high pressure air (in different grain sizes according to the purpose) and abrades the layer on the part.

Silica:

Silica sand, which is available in very fine varieties, is generally used for light sandblasting of thin sheet metal.

Basalt:

This sand, which is considered to have low dusting, is generally used in indoor environments where sand can be recycled.

Grit:

This he type of sand with the least dusting and the best sandblasting power. It is not actually sand but iron slag.

APPLICATION OF THE SANDBLASTING PROCESS;

Sandblasting is the throwing of the sand described above onto the metal surface with high pressure air to cause an impact on the surface. During this impact, the sand abrades the metal surface at the micron level while at the same time scraping and cleaning all kinds of unwanted substances from the surface.

AUTOMATIC SANDBLASTING;

This process is usually performed on steel structural elements that have not yet been cut or welded, or on steel material that has been cut and welded to a certain extent in automatic machines. The advantage of this system is that material large enough to enter the machine can be blasted quickly and economically.

1 • Degreasing line (Plastic and Metal products)

2 • Zinc phosphating (Metal and vulcanized parts)

3 • Zinc-Nickel plating (Metal and vulcanized parts)

Although the iron content that will participate in the coating provides the coating with exceptional corrosion resistance; it is not recommended as ratios above 1% make it difficult to passivate. Zinc Iron Plating Features: Suitable for drum and hanger and with very good metallic dispersion, Iron content adjustable from 0.3 to 1.0% (1% not recommended), Working range from semi-gloss coating to high gloss zinc coatings, Cyanide free, easy waste water treatment, No hydrogen embrittlement on heat treated and hardened parts, very ductile, suitable for uniform coating and chrome skipping, excellent metal dispersion and wrapping power.

As a result of corrosion problems and the prolongation of warranty periods in the automotive sector, surface protection processes are being renewed according to the conditions of the age in order to make longer-lasting parts every day. The zinc nickel process is one of them. In order to make this process work, strong technical staff and equipment consisting of control instruments are required.

This process, which is a necessity in today's conditions, is arguably the best process for Zinc Nickel alloy coating with its excellent adhesion and high corrosion resistance for parts operating at high temperatures. The process, which was originally introduced about 20 years ago, has been developed in today's technology and has become an indispensable alternative especially for automotive manufacturers with its bath dominance in many applications, coating quality and excellent distribution in low amperage areas.

There are two types of zinc nickel applications;

1 • Low nickel alloy 4-9 %

2 • High nickel alloy 8-15 %

Zinc Nickel Plating Properties;

1 • Alkaline zinc coating (Cr+3 passivation for metal and vulcanized parts) Non-alloy zinc coating with homogeneous metal distribution and blue, yellow, black and green passivation. The problems of fullness and sediment in fasteners such as Bolts, Nuts, Torque, Imbus, Allen, Washers have been eliminated with this system.

2 • 12-16% Nickel content

3 • Compliant with automotive standards

4 • High abrasion resistance

5 • Homogeneous coating thickness over the entire surface

6 • Environmentally friendly coating

7 • High corrosion resistance

8 • Uniform coating thickness over the entire surface of the part

9 • Price/Performance suitability

10 • High corrosion resistance

11 • Passivation and Lacquer applications

12 • Environmentally friendly coating

13 • Degreasing (related to finished products)

Adhesive Application 

1 • Gun Spraying

2 • Automatic robotic Spraying

3 • Spraying with the apparatus system

4 • Boiler type spraying
