Abstract
The invention discloses a plastic flow guide net sizing technology. The technology is characterized in that after a plastic net is extruded out, dry type vacuum cooling sizing is carried out on the plastic net in a sizing device, and then the plastic net is cooled in a cooling water tank; in the dry type vacuum cooling sizing process, the vacuum degree is controlled to be minus 0.5 barometric pressure to minus 0.8 barometric pressure; water cooling is carried out on the periphery of a sizing frame, and the cooling temperature is controlled to range from 20 DEG C to 30 DEG C; the roughness of the contact portion of the sizing device and the plastic net is controlled to be 1 micrometer to 1.5 micrometers; the vacuum cooling sizing time is 9 seconds to 21 seconds. According to the technology, the plastic net with the mesh diameter of 0.5 mm to 4 mm can be produced; the thickness stability of the plastic net is quite high, the surface of the plastic net is stable, the warp and weft shape of the meshes is stable, and the technology completely meets the high-standard requirement of the antiosmosis water industry.
Description
Technical field
The present invention relates to plastics flow-guiding screen setting process.
Background technology
The expressing technique of plastic wire shaping and the 1950's.Invented by the Frank Bryan Mercer of Britain.Traditional extrudes net after rotating head is extruded, and it cruelly leaked and naturally cool in atmosphere, then rolling, forms latticed plastic products.These latticed plastic products are mainly used as fence, the purposes such as packaging.Due to the restriction of shaping system, traditional handicraft can only produce the macrolattice plastic wire that Mesh Diameter is greater than 5mm, and the thickness of net can not accurately control, the shape of grid graticule and surface property also cannot accurately control, these coarse products can only be used as plastic fence, the low value purposes such as the packaging string bag, cannot meet the high request of water treatment field.
Summary of the invention
The object of the present invention is to provide a kind of plastics flow-guiding screen setting process, can the plastic wire of production department's Mesh Diameter between 0.5mm-4mm, and this plastic wire thickness stability is high, surface-stable, grid graticule dimensionally stable, meets the high standard requirement of reverse osmosis water industry completely.
For achieving the above object, the present invention redesigned plastic grid from rotating head out after sizing process for cooling, in shaping equipment, carry out dry vacuum cooling and shaping after plastic net extrusion, then cool in bosh; In the process of described dry vacuum cooling and shaping: vacuum degree control is at-0.5 ~-0.8 atmospheric pressure, and this will make the dimensionally stable of product, controlled; Water cooling is carried out in the periphery of shaping rack, and controlled cooling model temperature is at 20 ~ 30 degree, and this will be a significant benefit to the stability of improving the quality of products; The position roughness that shaping equipment contacts with plastic wire controls at 1-1.5 μ, and the surface roughness of shaping equipment can affect the roughness of final products graticule; Vacuum cooled shaping time is 9 ~ 21 seconds.
Advantage of the present invention and beneficial effect are: provide a kind of plastics flow-guiding screen setting process, can the plastic wire of production department's Mesh Diameter between 0.5mm-4mm, and this plastic wire thickness stability is high, surface-stable, grid graticule dimensionally stable, meets the high standard requirement of reverse osmosis water industry completely.
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
The technical scheme that the present invention specifically implements is:
The present invention redesigned plastic grid from rotating head out after sizing process for cooling, in shaping equipment, carry out dry vacuum cooling and shaping after plastic net extrusion, then cool in bosh; In the process of described dry vacuum cooling and shaping: vacuum degree control is at-0.5 ~-0.8 atmospheric pressure, and this will make the dimensionally stable of product, controlled; Water cooling is carried out in the periphery of shaping rack, and controlled cooling model temperature is at 20 ~ 30 degree, and this will be a significant benefit to the stability of improving the quality of products; The position roughness that shaping equipment contacts with plastic wire controls at 1-1.5 μ, and the surface roughness of shaping equipment can affect the roughness of final products graticule; Vacuum cooled shaping time is 9 ~ 21 seconds.
The plastic grid that present invention process is produced has following characteristic:
Web thickness uniformity good (demand comes from the process for machining and manufacturing of membrane component, otherwise it is large to roll out the membrane component diameter difference come, and in the assembling of terminal client place and cannot use)
Grid graticule surface roughness is stablized;
Grid graticule dimensionally stable and controlled;
The most I of Mesh Diameter reaches 0.5mm.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
