Why is it necessary to deal with it before using Shandong color steel composite board adhesive?
(1) Before the surface treatment of the bonded parts, there are oil stain, film remover, weathering layer, carbonization layer or rust layer, etc. These unclean and unsound surface layers, if not removed, will affect the bonding performance.
For example, sandblasting can increase the bonding area of the polished metal surface by 20 times. In addition, the rough surface can make the solidified adhesive form more meshing structure with the object to be adhered, which is proved by theory and
(3) Surface treatment can improve the surface properties. For example, chemical treatment of metal surface can increase the surface tension on the surface of the object to be adhered, so as to improve the adhesive strength. For some hard
to stick low-energy surfaces, plastics and rubber, effective bonding can only be carried out after surface treatment (such as using sodium naphthalene solution to treat tetrafluoroethylene), and the surface treatment with coupling agent can also improve
the bonding performance So the surface treatment is very important in the bonding process.
Shandong color steel composite board black and white glue is mainly used in the adhesion of color steel and stainless steel objects, in addition to the adhesion
of building materials. With the emergence of these industries, the use of color steel black and white glue is also surging, these industries are driving the use efficiency of these black and white, in order to produce more industrial products, in some
processing areas also need to be rectified, so the practical characteristics of color steel black and white glue meet their production needs. So the following is a brief introduction to some characteristics of color steel black and white glue.
It is used in many fields of industrial production
In many industrial production, Shandong color steel composite board black and white glue is used, 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, which makes it closely related to industrial production.
2. It overcomes the limitation of poor toughness
of traditional glue
Its change makes the tenacity and strength of glue meet the needs of workers. It also overcomes the limitation of the poor hydrolysis performance of traditional glue, making the current glue has better anti hydrolysis performance.
This glue has a strong viscosity.
3. Not easy to aging
Using this kind of black and white glue for color steel, the aging will be slowed down, and its activity will be maintained to a great extent, so that the adhered objects will maintain
more lasting cohesiveness.
4. The flow of the product is good
Glue in the use of the process will be inadvertently blocked by the glue extension, but this color steel glue does not have this worry, because its smooth performance is particularly
good. It will not be blocked.
