Embodiment 1

[0066] This embodiment provides a filter net, which is obtained in the following manner. According to the mass ratio of silicon oxide: aluminum oxide: boron oxide: calcium oxide: magnesium oxide: bismuth oxide: titanium oxide = 40:16:12:8:8:10:6, weigh the raw materials and mix them evenly to obtain metal oxides Powder. The metal oxide powder is heated up to 1550 degrees Celsius with the furnace, and melted at 1550 degrees Celsius for 2.5 hours to obtain molten glass. Pour the molten glass into the mold, anneal at 200 degrees Celsius for 2.5 hours, and then cool with the furnace to obtain a glass body. The glass body is subjected to drawing treatment at a temperature ranging from 500 degrees Celsius to 510 degrees Celsius to obtain glass fibers. By glass fiber: polyethylene terephthalate resin: polycarbodiimide: polybenzobisoxazole: bisphenol A phosphite: polytetrafluoroethylene = 30:65:1:1:1: 2 mass ratio, weigh glass fiber, polyethylene terephthalate resin, polycarbodiimi...

Embodiment 2

[0068]This embodiment provides a filter net, which is obtained in the following manner. According to the mass ratio of silicon oxide: aluminum oxide: boron oxide: calcium oxide: magnesium oxide: bismuth oxide: titanium oxide = 48:14:10:6:6:10:6, weigh the raw materials and mix them evenly to obtain metal oxides Powder. The metal oxide powder is heated up to 1600 degrees Celsius with the furnace, and melted at 1600 degrees Celsius for 3 hours to obtain molten glass. Pour the molten glass into the mold, anneal at 250 degrees Celsius for 3 hours, and then cool with the furnace to obtain a glass body. The glass body is subjected to drawing treatment at a temperature ranging from 530 degrees Celsius to 540 degrees Celsius to obtain glass fibers. By glass fiber: polyethylene terephthalate resin: polycarbodiimide: polybenzobisoxazole: bisphenol A phosphite: polytetrafluoroethylene = 55:40:3:0.5:0.5: 1 mass ratio, weigh glass fiber, polyethylene terephthalate resin, polycarbodiimid...

Embodiment 3

[0070] This embodiment provides a filter net, which is obtained in the following manner. According to the mass ratio of silicon oxide: aluminum oxide: boron oxide: calcium oxide: magnesium oxide: bismuth oxide: titanium oxide = 40:16:12:8:8:10:6, weigh the raw materials and mix them evenly to obtain the first metal oxide powder. The first metal oxide powder was heated up to 1550 degrees Celsius with the furnace, and melted at 1550 degrees Celsius for 2.5 hours to obtain the first molten glass. Pour the first molten glass into the mold, anneal at 200 degrees Celsius for 2.5 hours, and then cool with the furnace to obtain the first glass body. The first glass body is subjected to drawing treatment at a temperature ranging from 500 degrees Celsius to 510 degrees Celsius to obtain first glass fibers. According to the mass ratio of silicon oxide: aluminum oxide: boron oxide: calcium oxide: magnesium oxide: sodium oxide: yttrium oxide: thulium oxide = 40: 16: 12: 8: 8: 10: 4: 2, w...

Abstract

The invention provides a filter screen and a manufacturing method thereof. The manufacturing method of the filter screen comprises the following steps: step S101, weighing organic materials and uniformly mixing to obtain a mixed material; step S102, carrying out mixing, extrusion and granulation on the mixed material obtained in the step S101 and an inorganic toughening agent in a temperature range of 220-240 DEG C by adopting double-screw extrusion equipment to obtain a composite material; and step S103, melting the composite material obtained in the step S102 in a temperature range of 200-220 DEG C by adopting injection molding equipment, and then feeding the molten composite material into a mold for molding and cooling to obtain the filter screen. The filter screen with high mechanical strength and excellent quality can be obtained.

Description

technical field [0001] The invention relates to the field of plastic material manufacturing, in particular to a filter net and a manufacturing method thereof. Background technique [0002] The filter screen is an essential and important component in air purification equipment and sewage treatment equipment. It usually uses a polymer material such as polyethylene terephthalate (English name: polyethylene terephthalate, English abbreviation: PET) as a raw material. One of the deficiencies in the related art is that the mechanical strength and wear resistance of the filter screen made of polyethylene terephthalate plastics are not ideal enough. Contents of the invention [0003] One of the technical problems to be solved by the present invention is to improve the mechanical strength and wear resistance of the filter screen using polyethylene terephthalate plastic as raw material. [0004] To solve the above problems, the present invention provides a filter net and a manufac...
