Abstract
The invention discloses a manufacturing method for a composite framework screen stencil. A square steel pipe or a piece of flat steel is selected, and the square steel pipe or the piece of flat steel is welded into a framework structure; injection moulding treatment is performed on the framework structure, a three-layered filter screen is manufactured, and the framework structure treated by injection moulding and the three-layered filter screen are placed on a fuse machine for hot-melting treatment; and the framework structure treated by hot-melting and the three layered filter screen are placed at an ordinary temperature for solidification for a period of time to obtain an end product. The manufacturing method for the composite framework screen stencil, provided by the invention, uses hot-melting technology to manufacture the screen stencil, and the screen stencil manufactured through the method has the characteristics of long service life and excellent screening rate.
Description
Technical field
The present invention relates to a kind of manufacture method of compound frame screen cloth.
Background technology
MONGOOSE compound frame screen cloth is made up of framework and filter screen, current screen cloth processing technology is that filter screen binding agent is fixed on framework surface, the wire side adhesive segment using binding agent fixing is more easy to wear, service life is not grown and the wire side out-of-flatness of screen cloth, uses and do not reach due effect under rugged environment.
Summary of the invention
The invention provides a kind of manufacture method of compound frame screen cloth, use the screen cloth that hot-melt technology manufactures, the screen cloth long service life manufactured according to the method, the feature that screening percentage is good.
Present invention employs following technical scheme: a kind of manufacture method of compound frame screen cloth, comprises the following steps: step one: choose rectangular steel tube or band steel, and rectangular steel tube or band steel are welded into frame structure; Step 2: injection process is carried out to frame structure shaping in step one, the injected plastics material chosen in injection process process is according to MODIFIED PP 65%-85%, the proportions of glass fibre 15%-35%, by the frame structure of injected plastics material powder injection moulding after having prepared; Step 3: the making carrying out three metafiltration nets, to choose order number be 20 string diameters is that the stainless steel filtering net of 0.3-0.5mm makes spacer screen, to choose order number be 40-80 string diameter is that the stainless steel filtering net of 0.05-0.1mm makes middle net, to choose order number be 100-325 string diameter is that the stainless steel filtering net of 0.03-0.06mm makes working net, and three forms three metafiltration web frames; Step 4: the frame structure after injection moulding and three metafiltration web frames are placed on fuse machine and carry out hot melt process; Step 5: the frame structure after hot melt process in step 4 and three metafiltration nets are placed in ambient temperature curing a period of time, obtain finished product.
Framework 60-90s is melted by the temperature of 200-245 DEG C during hot melt process in described step 4; Frame structure in described step 5 after hot melt process and three metafiltration nets are placed in ambient temperature curing 60-80s.
The present invention has following beneficial effect: the present invention's features such as intensity is high, solid, firm, wire side is smooth, screen-penetrating performance is good, long service life that use the screen cloth of hot-melt technology manufacture to have.
