Hot Melt Adhesive Used For Air Filter Product

The filter products we are familiar with are divided into two categories: air filter and liquid filter according to the filter medium. Binding Agent often used in these two types of filter products, and the main function is to solve the process needs of the filter in the manufacturing process of bonding, shaping, sealing and so on. Hot Melt adhesive is widely used in the filter manufacturing industry because of its environmental protection, safety, temperature resistance, fast curing speed, high production efficiency and simple gluing operation.

Introduction to the gluing process in the manufacturing process of automotive engine intake filter:
In the manufacturing process of the automobile engine intake filter, the whole roll of filter paper is first installed on the origami machine, and the width of the origami paper is set according to the size specifications of the filter product; After the folding and forming of the filter paper, the Hot Melt Glue quickly enters the spraying process of the hot melt glue on the folded and forming filter paper, and the hot melt glue spray fixed glue line at a uniform speed on each side, which plays the function of sealing, and the hot melt glue quickly solidifies and bonds, so that the folded filter paper is fixed and formed without springing open; Then according to the specifications of the filter cut into a specific size, into the mold, and then PU foam bonding and filling.

Application characteristics of automotive engine intake filter:
With conventional tolerance, usually the engine air intake filter, in terms of high temperature: the softening point of 85 ° C is required, and the high temperature passing test of 60 ° C is required, and there are special requirements to reach 110 ° C high temperature passing test; In terms of low temperature: it is required to meet the natural preservation safety in the environment of -10~-20℃. With the improvement of quality and product matching requirements of engine air filter manufacturers, they will put forward color requirements for hot melt adhesives, generally choose two kinds of light yellow and yellow, in order to improve the beauty of the product, there are also light-colored filter paper with white hot melt adhesives, such hot melt adhesives have good thermal stability and excellent quality.
