Problems solved by technology

Its disadvantages are: the two-liquid casting process is relatively complicated, and the composite quality is unstable; the surface spraying process has a thin composite thickness, high cost, and low bonding strength, which is prone to falling off under high stress
Due to many problems in this process, there is no precedent for large-scale industrialization and batch application in the manufacture of composite liners

preparation example Construction

[0038] The preparation process of the above-mentioned wire mesh composite liner 1 can be realized through the following steps:

[0039] a. Directly weave the overall wire mesh with metal wire (1);

[0040] b. Cut the wire mesh (1) according to the specification and size of the composite liner, and carry out pickling treatment;

[0041] c, prepare composite filler (2);

[0042] d. Place the treated wire mesh (1) in the mould, vibrate on a three-dimensional vibration table or place it on a vulcanizer or press, and inject the composite filler (2) into the wire mesh (1) under high pressure;

[0043] e. After vibration drying, curing molding, demoulding and trimming, the metal mesh composite liner is prepared.

[0044] Form 2: see figure 2 . The nano-structure wire mesh composite liner 2 is composed of a wire mesh (1) and a composite filler (2), and the wire mesh (1) is composed of a single-layer wire mesh into a multi-layer wire mesh. Bolts (3) or other means are fastened as...

[0057] Preparation process of nanostructure wire mesh-rubber composite liner

[0058] The technological process of preparing nanostructure wire mesh-rubber composite liner, see image 3 .

[0059] a. First, weave nanostructured wire mesh 1 according to the size of the liner, and process it according to the process;

[0060] b. Preparation of composite filler-rubber raw material 2, the steps are: the raw rubber is chopped, masticated and mixed with a compounding agent (0.8-1.2% carbon black by weight), and mixed in a mixer;

[0061] c. Putting the assembled, compressed and fixed nanostructure wire mesh 1 into the mold of the vulcanizing machine;

[0062] d. Inject the kneaded raw rubber into the nanostructure wire mesh 1 under high pressure, pressurize 10-50 tons, and keep it warm at 100-120°C for 1-3 hours, the best time is 2 hours; then,

[0063] e. Carry out molding, vulcanization, demoulding and trimming to make qualified products.

Abstract

The present invention discloses a kind of nano structure wire gauze composite lining plate and its preparation process. Said lining plate is made up by using wire gauze and compounded filing materialthrough a compositive process. Said wire gauze can be integrally braided, also can be a multilayer structure pieced by using single-layer of wire gauze, said wire gauze can be placed in the interior of compounded filling material, then they are combined into a whole body. Said composite lining plate possesses high wear-resistance, water-resisting property, vibration-absorbing property and corrosion-resisting property, etc..

Description

Technical field [0001] The invention relates to a metal composite liner in the fields of general crushing, grinding, conveying, flotation, crushing, and environmental protection and a preparation process thereof, in particular to a nanostructure metal wire mesh composite liner and a preparation process thereof. technical background [0002] Lining plates on machinery such as crushing, milling, flotation, and conveying, which are widely used in metallurgy, mining, electric power, building materials, refractory materials, energy, and environmental protection, are the main wear parts. At present, there are three main series of materials that can be used to make liners: (1) Manganese steel series - only under high-load, high-impact wear conditions, its wear resistance can be fully exerted; (2) Multi-element low-alloy steel Series - the hardness of the matrix structure changes in the range of HV500-1000, which is lower than that of cementite and special carbide; (3) chromium seri...
