Why do you want to use Shandong color steel composite plate glue before processing?

Why do you want to use Shandong color steel composite plate glue before processing?

(1) before the surface treatment of the adhesive parts, often with oil, stripping agent, weathering layer, carbonization layer or rust layer, these are not clean, not solid surface layer, if not removed, will affect the bonding performance.

(2) The rough grain treatment on the surface of the adherend can increase the actual bonding area of the adherend. For example, sandblasting can increase the bonding area of the polished metal surface by 20 times. In addition, the rough surface can form more meshing structures between the cured adhesive and the adherend-mechanical bonding force and improve the bonding strength, which has been confirmed by theory and practice.

(3) surface treatment can improve the surface properties, such as chemical treatment of metal surface, can improve the surface tension on the surface of the adherend, so as to improve the adhesive bonding strength, some difficult to stick low energy surface, plastic and rubber, after surface treatment can be effective bonding (such as sodium naphthalene solution treatment of tetrafluoroethylene), coupling agent on the surface treatment can also improve the bonding performance, therefore, surface treatment is very important in the bonding process.

Shandong caigang composite plate black and white glue is mainly used in the adhesion of caigang and stainless steel objects, in addition to the adhesion of building materials. With the sudden emergence of these industries, the use of color steel black and white glue is also surging, these industries are driven by the efficiency of the use of these black and white, in order to more production of industrial supplies, in some processing areas of the link to be rectified, so the practical characteristics of color steel black and white glue to meet their production needs. Then the following is a brief introduction of some of the characteristics of the color steel black and white glue.

1, applied to many fields of industrial production

In many industrial production are used in Shandong color steel composite board black and white glue, such as color steel industry, stainless steel industry and the rapid development of building materials wood industry. Therefore, although it is a small object in the production process, it is essential. It involves a lot of industrial production makes it closely related to industrial production.

2. Overcome the limitation of poor toughness of traditional glue in the past

Its change makes the toughness strength of the glue more able to meet the needs of the work. It is also the limitation of poor hydrolysis performance of traditional glue, which makes the hydrolysis resistance of the glue now better. The viscosity of this glue is relatively strong.

3, not easy to aging

The use of this color steel black and white glue aging will slow down, to a large extent to maintain its activity, so that the adhesion of the object to maintain a more durable viscosity and sex.

4. The product has good pouring fluency

Glue in the use of the process will be inadvertently blocked by the glue extension, but this color steel glue is not such a worry because of its smooth performance is particularly good. There will be no blockage.
