Problems solved by technology

[0002] Welding steel plate is to use electric welding machine to weld and mend steel plate outside the equipment or pipeline that leaks due to wear and tear. The method of repair welding can hardly solve the problem, even if it is forced to repair welding, it cannot solve the problem of enhanced wear resistance
[0003] Pasting wear-resistant ceramics is to paste aluminum oxide ceramic sheets with epoxy resin on the inner wall of equipment or pipelines that leak due to wear and tear. The absence of spare parts does not solve field problems
[0004] With the rapid development of the coal washing and washing industry in coal mines, the workload caused by the wear and tear of coal washing and washing equipment is increasing, which delays production time, and at the same time causes serious environmental pollution in the workshop due to on-site leakage.
[0005] At present, there is no product that can better solve this maintenance problem

Embodiment 1

[0033] A ceramic fiber modified wear-resistant adhesive, comprising the following components (by mass percentage):

[0034] Component A (main agent):

[0035]

[0036]

[0037] Component B (curing agent):

[0038]

[0039] In the coal centrifuges commonly used in coal washing plants, the outer opening of the casing screen is often severely worn. For a coal washing plant with an annual washing capacity of 5 million tons, after the centrifuge shell is worn out, it is repaired with a 30mm thick 16 manganese steel plate, which wears out after 20 days, resulting in coal slime water leakage. After 10 days, the worn-off steel plate fell and caused the conveyor belt under the centrifuge to tear.

[0040] The beneficial effects of this embodiment are: use the ceramic fiber modified wear-resistant adhesive of the present invention to cooperate with wear-resistant ceramics for repairing, fill the worn holes and grooves with the ceramic fiber modified wear-resistant adhesive, a...

Embodiment 2

[0043] A ceramic fiber modified wear-resistant adhesive, comprising the following components (by mass percentage):

[0044] Component A (main agent):

[0045]

[0046] Component B (curing agent):

[0047]

[0048] The beneficial effects of this embodiment are: the concentrator is an important equipment for coal slime water treatment and recycling in coal washing plants, the feed pipeline is an overhead pipeline, the diameter is usually 327mm-800mm, the medium is coal slime water, and there are more points after 2 years of use The bit is worn out, and then repaired by replacement and welding methods, which cannot solve the wear problem, and cause problems that affect the appearance of the workshop equipment.

[0049] Use the material ceramic fiber modified wear-resistant adhesive of the present invention to repair, use the material ceramic fiber modified wear-resistant adhesive of the present invention to repair directly from the inner wall, mixing ratio: weight ratio / vo...

Embodiment 3

[0051] A ceramic fiber modified wear-resistant adhesive, comprising the following components (by mass percentage):

[0052] Component A (main agent):

[0053]

[0054] Component B (curing agent):

[0055]

[0056] The beneficial effect of this embodiment is: the feed pipe of the filter press in the coal washing plant, the internal medium is coal slime water, the medium leaks due to the wear of the elbow joint and the flange, and the thickness of the pipe wall is only 2mm, which cannot be welded.

[0057] Use the ceramic fiber modified wear-resistant adhesive material of the present invention to repair, and use the ceramic fiber modified wear-resistant adhesive material of the present invention to directly apply the repair from the outer wall, mixing ratio: weight ratio / volume ratio (main agent: curing agent) 1.5:1 / 1.2:1; the viscosity after mixing is paste; the operating time is 45-60 minutes; the curing time is 9 hours; the hardness (Shore D) after curing is 87; the sh...

Abstract

A ceramic fiber modified wear-resistance adhesive comprises components (in weight percentage) including components A comprising 17-19% of modified epoxy resin E44, 1.7-1.9% of silane coupling agent A-1160, 1.9-2.1% of diluents 690, 1.3-1.5% of liquid polysulfide rubber, 2.9-3.1% of ceramic fibers, 4.9-5.1% of organic bentonite, 0.75-0.85% of flame retardant, 7-9% of 160-mesh quartz sand and 28-32% of 1.5mm wear-resistant aluminum oxide ceramic balls, and components B comprising 7-9% of curing agent T31, 0.18-0.22% of DMP-30 promoter, 0.9-1.1% of ceramic fibers, 0.75-0.85% of organic bentonite, 4-6% of 160-mesh quartz sand and 14-16% of 1.5mm wear-resistant aluminum oxide ceramic balls. The ceramic fiber modified wear-resistant adhesive has the advantages of high maintenance efficiency, short maintenance time, low construction difficulty and fine wear resistance effect.

Description

technical field [0001] The invention relates to an adhesive, in particular to a ceramic fiber modified wear-resistant adhesive used for wear-resistant repair and protection of equipment maintenance. Background technique [0002] Welding steel plate is to use electric welding machine to weld and mend steel plate outside the equipment or pipeline that leaks due to wear and tear. The method of repair welding can hardly solve the problem, even if it is forced to repair welding, it can not solve the problem of enhanced wear resistance. [0003] Pasting wear-resistant ceramics is to paste aluminum oxide ceramic sheets with epoxy resin on the inner wall of equipment or pipelines that leak due to wear and tear. The absence of spare parts cannot solve field problems. [0004] With the rapid development of the coal washing and washing industry in coal mines, the workload caused by the wear and tear of coal washing and washing equipment is increasing, which delays production time, an...
