Embodiment 1

[0039] The preparation method of the composite sintered board of the present embodiment comprises the following steps:

[0040] 1) Select ultra-high molecular weight polyethylene with a molecular weight of 3.5 million and a particle size of 60-80 meshes as the resin base powder; use 5 fiber filaments (the diameter of a single fiber filament is 1 μm) to form a fiber tow for weaving processing, Made 100 mesh T300 carbon fiber mesh fabric as reinforcement material.

[0041] 2) Place the mold with a cavity height of 6mm horizontally, and spread the resin powder and the mesh fabric at intervals, respectively, from bottom to top, with one to five layers, of which the first, third and fifth layers are resin powder, and the second and fourth layers are made of resin powder. The layer is made of carbon fiber mesh fabric, and the thickness of the resin powder is spread evenly. After each layer is spread, it is vibrated to make the material dense. After the mold is closed, it is placed v...

Embodiment 2

[0045] The preparation method of the composite sintered board of the present embodiment comprises the following steps:

[0046] 1) Select polytetrafluoroethylene resin dry powder with a molecular weight of 10 million and a particle size of 80-120 mesh as the resin base powder; select a stainless steel wire mesh with a diameter of 5 μm and a mesh of 150-200 mesh as the reinforcing material.

[0047] 2) Place the mold with a cavity height of 10mm horizontally, spread polytetrafluoroethylene powder and stainless steel wire mesh at intervals, the first, third, fifth and seventh layers are polytetrafluoroethylene powder, the second and fourth layers And six layers are stainless steel fiber mesh. Spread the resin powder thickness evenly, and vibrate after each layer of paving to make the material compact. After closing the mold, place it vertically according to the actual use direction, and then put it into the sintering furnace after vibrating.

[0048] 3) Carry out four-stage gr...

Embodiment 3

[0051] The preparation method of the composite sintered board of the present embodiment comprises the following steps:

[0052] 1) Select P2 type polyphenylene sulfide with a particle size of 100-150 mesh as the resin base powder; weave the fiber tow formed by 10 fiber filaments (the diameter of a single fiber filament is 17 μm), and make 150 -200 mesh basalt fiber mesh fabric as reinforcement.

[0053] 2) Place the mold with a cavity height of 4 mm horizontally, spread polyphenylene sulfide powder and basalt fiber fabric at intervals, the first and third layers are polyphenylene sulfide powder, and the middle layer is basalt fiber fabric. Spread the resin powder thickness evenly, and vibrate after each layer of paving to make the material compact. After closing the mold, place it vertically according to the actual use direction, and then put it into the sintering furnace after vibrating.

[0054] 3) Carry out three-stage gradient sintering in the sintering furnace. The fir...

Abstract

The invention relates to a composite sinter plate and a preparation method thereof, and a s sinter-plate dust catcher. The composite sinter plate comprises a plastic filter substrate and a reinforcingmaterial compounded in the plastic filter substrate, wherein the reinforcing material comprises one or two selected from reinforcing fibers and a reticular fabric, wherein the reticular fabric is formed by weaving the reinforcing fibers and is arranged in a direction parallel to the length direction of the composite sinter plate. According to the composite sinter plate provided by the invention,the sinter plate is modified by the reinforcing material, so the tensile strength and modulus of the sinter plate can be enhanced; and thus, the sinter plate is prevented from being broken and damagedin the process of repeated back-flushing.

Description

technical field [0001] The invention belongs to the field of plastic-sintered boards (sintered boards), and in particular relates to a composite plastic-sintered board, a preparation method thereof, and a plastic-sintered board type dust collector. Background technique [0002] The existing traditional bag-type dust filter material has a good interception and capture effect on dust, has been widely used in many fields, and has become an important technical means of environmental protection. However, the bag filter also has many shortcomings, such as high emission concentration, short service life, high replacement frequency, and high energy consumption. Moreover, with the country's increasingly strict environmental protection and the gradual increase of emission standards, the bag filter can no longer meet the new requirements. In order to solve these problems, in recent years, people have developed a so-called plastic burning plate dust collector to replace the bag dust co...
