Title: Formation of thermally sprayed film
Inventor: SAKURADA TSUKASA
IPC: C04B35/00
Filed: 1986-04-30
Abstract: PURPOSE:To easily form a thermally sprayed film having good adhesive strength and excellent characteristics by forming the sprayed film on a backing film, then adhering the front side of the sprayed film onto a base material and stripping the film. CONSTITUTION:The thermally sprayed film 12 is first formed by thermal spraying a thermal spraying material onto the backing film 10. The front side of the sprayed film 12 is then adhered and fixed onto the necessary base material 14 by using an adhesive agent. The backing film 10 is stripped from the sprayed film 12 to expose the rear side of the sprayed film 12. Then, the surface of the sprayed film on the backing film is strongly adhered to the base material consisting of plastic, etc., even if said surface is rough. In addition, the use of the film by exposing the rear side having high smoothness is also possible. The sprayed film on the backing film is freely cuttable and the sprayed film of an optional shape is easily formable on the base material.

IPC: B01D53/04
Filed: 1981-06-29
Abstract: PURPOSE:To prevent active carbon from being separated off, by a method wherein a part of the surface of particulate active carbon is adhered to the surface of a porous sheet with a glueing material which substantially does not penetrate into pores of the active carbon. CONSTITUTION:The glueing material is preferably a synthetic resin having a low melting point, while the porous sheet is preferably made of a cloth, paper, a nonwoven fabric or a foamed synthetic resin. Particulate active carbon having an average particle  diameter of 50-2,000mu is used. The particulate active carbon is adhered to the surface of the porous sheet preferably in such a manner that each particle 1 of the active carbon is embedded in the glueing material 2 to a depth equal to 1-10% of the particle diameter and the particles are spaced from each other by an appropriate distance of  up to several times of the particle diameter so that they do not overlap with each other. The part of each carbon particle adhered to the glueing material corresponds to about 1/6 of the surface area of the particle, namely, only a small part of the total volume which contributes to the adsorbing capability, so that the adhesion scarcely damage the adsorbing capability. In addition, there is no evidence of damage on the active carbon due to penetration of the glueing material into the pores of the active carbon.
