Abstract
A method for processing electromagnetic shielding plate for building includes such steps as cutting substrate according to needed size, grinding, roughening the surface of substrate, removing floating dust, smelting the metallic material with electromagnetic shielding function by hot spraying device, atomizing the molten metallic material, and spraying it onto the ground substrate to form a shielding layer. The shielding coating is made of metal material with electromagnetic shielding effect, and has sufficient attenuation effect on electromagnetic wave energy, so that the electromagnetic shielding plate can be directly installed on the light steel keel member to form a shielding wall with electromagnetic shielding effect, thereby shortening the labor hour consumed by building installation and reducing the cost consumed by building materials.
Description
Technical field
The present invention relates to the working method of a kind of working method of building board, particularly a kind of electromagnetic shielding plate for construction.
Background technology
Existing building board is chosen substrate according to size cutting earlier usually, and then the surface of substrate carried out anti-oxidant and refractory process, so that building board adapts to the universal demand of building trade, but its electro-magnetic screen function of building board that goes out according to present processes a little less than, when building board is applied to construct shield wall, this building board is installed in usually and forms wallboard on the Lightgage Steel Joist, also need to install again shielding slab in the interior outside of wallboard with electromagnetic shielding action, to form shield wall, its installation process is cumbersome, and can cause increasing of material of construction cost.
Summary of the invention
The object of the invention provides a kind of working method of electromagnetic shielding plate for construction, can process the building board with stronger electro-magnetic screen function.
Technical scheme of the present invention is: a kind of working method of electromagnetic shielding plate for construction, and it comprises the following steps,
1., size cutting substrate according to demand;
2., substrate surface is carried out grinding, with the surface of hacking substrate, and remove the floating dust that stays after the grinding;
3., the metallic substance that will have an electromagnetic shielding action with thermal spraying apparatus melts, then with the melt metal atomising material and be ejected into through the substrate surface after the ground, to form curtain coating at substrate surface.
Step 2. in, adopt the abrasive band that substrate surface is carried out grinding.
Step 3. in, the thickness of the curtain coating of described substrate surface is processed as 0.10～0.50mm.
The present invention compared with prior art, have following advantage: curtain coating adopts the metallic substance with electromagnetic shielding action to make, it has enough attenuations to electromagnetic wave energy, make this electromagnetic shielding plate can be directly installed on the shield wall that formation has electromagnetic shielding action on the Lightgage Steel Joist member, both the man-hour that construction and installation consume can be shortened, the cost that material of construction consumes can be reduced again.
Embodiment
A kind of working method of electromagnetic shielding plate for construction, it comprises the following steps:
1., size cutting substrate according to demand;
2., adopt the abrasive band to carry out grinding, with the surface of hacking substrate, and remove the floating dust that stays after the grinding to substrate surface;
The metallic substance thawing that 3., will have electromagnetic shielding action with thermal spraying apparatus, then with the melt metal atomising material and be ejected into through the substrate surface after the ground, to form curtain coating at substrate surface, the thickness of formed curtain coating must be controlled at 0.10～0.50mm.
Following mask body is introduced a specific embodiment of the present invention:
According to the order requirement of client to fiber cement board, fiber reinforced calcium silicate board (hereinafter to be referred as substrate), at first substrate to be cut, the overall dimension of cutting substrate is 3050mm
*1220mm
*(4～14) mm, then to selecting the abrasive band of 40#～80# to carry out grinding and remove floating dust by sprayed surface, purpose is that substrate surface is carried out hacking and clean, helps combining of curtain coating and substrate.Then the thermospray shielding processing is implemented on the surface.This method is selected the metallic substance (as: copper, zinc, stainless steel, lead etc.) that hertzian wave is had shielding effect for use, utilize spray gun to produce short circuiting arc, the high heat energy that is produced by electric arc melts wire or powder, then by the compressed air of per second more than 600 meters with melt metal silk or dust cloudization, accelerating jetting is to the pretreated plate surface of process, the translational speed speed is controlled, with substrate curtain coating than high bond strength is arranged with what obtain required 0.10～0.50mm thickness.And then to the surface of plate seal, antioxidation treatment, make it both to have electromagnetic shielding action, meet building board versatility characteristics again.
Claims (3)
1, a kind of working method of electromagnetic shielding plate for construction is characterized in that: it comprises the following steps,
1., size cutting substrate according to demand, described substrate is fiber cement board or fiber reinforced calcium silicate board;
2., substrate surface is carried out grinding, with the surface of hacking substrate, and remove the floating dust that stays after the grinding;
3., the metallic substance that will have an electromagnetic shielding action with thermal spraying apparatus melts, then with the melt metal atomising material and be ejected into through the substrate surface after the ground, to form curtain coating at substrate surface.
2, the working method of electromagnetic shielding plate for construction according to claim 1 is characterized in that: step 2. in, adopt the abrasive band that substrate surface is carried out grinding.
