Abstract
This invention involves one kind to wear the surface to glue the wear-resisting potsherd the method, the characteristic is, including following step: 1. To needs the wear-resisting metal surface to eliminate the rust, damages, causes its surface roughness, scours: 2. Spreads a thickness in the metal surface is the cementing agent which 1-4 millimeter belt powdery ceramics solid particle thick thick liquid normal temperature solidifies; 3. Needs the wear-resisting metal surface the wear-resisting potsherd dependence above cementing agent even position year railroad, after 1-2 hour time solidification then. Because time cementing agent specially develops or selects is the thick thick liquid cementing agent, was equal to levels off originally the rugged metal surface, forms a flexible smooth cementing power greatly strengthened surface to cake the wear-resisting potsherd, therefore, the caking reliable degree is very good; Because develops the thick thick liquid cementing agent intensity which or selects basically with the caking time cakes the thickness to have nothing to do with, in the thick thick liquid cementing agent had the massive wear-resisting solid molecule to overcome the ordinary thin cementing agent because lacked the solid molecule to work as when the cementing agent thickness too was big, the caking intensity dropped, has fallen off shortcoming.
Description
Technical field
The present invention relates to a kind of method that the ash discharge fan blade is facingd the wind the surface or the wear-resistant ceramic sheet is pasted in surface easy to wear such as elbow in the conveying of things such as coal dust, lime-ash, ore in sand form.
Background technique
The ash discharge blower fan facing the wind impeller surface and in things such as coal dust, lime-ash ore in sand form are carried some surface as elbow wear phenomenon especially severe, influence the safety and economic operation of blower fan and conveying mechanism greatly, stop to produce if often overhaul, loss is very huge.Several thousand times of this blower fan or wearout parts value head and shoulders above, even more than up to ten thousand times, therefore to the blade of ash discharge blower fan facing the wind surface and coal dust, lime-ash, surface easy to wear such as elbow often adopted the method for pasting the wear-resistant ceramic sheet to increase wear resistance during ore in sand form was carried, but the surface smoothness that the requirement of stickup ceramic plate is stuck is very high, and the wear-resistant ceramic sheet that not so is stuck just easily comes off and causes the accident.Therefore at building-site wear plate is pasted in the uneven metal surface that is worn and just be difficult to carry out, perhaps sticking effect can not be satisfactory, easily comes off.
Summary of the invention
The objective of the invention is provides a kind of method of pasting the wear-resistant ceramic sheet to the metal surface, the uneven solid difficulty that is pasted not strongly in metal surface that is run into when needing the antifriction metal (AFM) surface to paste the wear-resistant ceramic sheet to solve.
Technological scheme of the present invention is: method may further comprise the steps:
1) iron rust is driven away with emery wheel in the wear-resisting metal surface of need, dirt, and hacking are used the acetone scrub again, make its rough surface;
2) be coated with the Bond of thick normal temperature cure that last layer thickness is the band powdered ceramic solid particle of 1-4 millimeter in the metal surface;
3) rely on wear-resisting ceramic plate above-mentioned Bond entirely to paste the wear-resisting metal surface of palpus, curing got final product through 1-2 hour time.
Since Bond be especial manufacture or what select for use is the thick Bond, equal original rough metal surface is filled and led up, the extremely strong surface of smooth cohesive force that forms the flexibility wear-resistant ceramic sheet that bonds, therefore, the firm degree of bonding is fine, and it is very sensitive that the firm degree that bonds when boning unlike common slim Bond is influenced by the adhesive thickness size.Because development or the thick Bond adhesion strength selected for use during basically with bonding adhesive thickness irrelevant, key is to have in the Bond of thick a large amount of wear-resisting solid tiny particles to overcome common slim Bond owing to lack solid tiny particle when adhesive thickness is too big, adhesion strength decline, caducous shortcoming.
Embodiment
The present invention illustrates its embodiment with an embodiment, and Minhang power plant ash discharge blower fan was the manganese steel blade originally, uses and promptly accuses wearing and tearing (wind speed 24 meter per seconds) in three months.To the blade after the wearing and tearing, then paste the wear-resistant ceramic sheet: 1, with emery wheel rust cleaning, polishing by the step of this method, make its blade coarse, clean with acetone again, remove ash, wet goods foreign material, after the whole volatilizations of acetone, though blade surface is clean and do not have the loose surface, the uneven surface that still has wearing and tearing to cause; 2,, therefore on blade surface, coat one millimeter to two, the three millimeters not Bond of the thick normal temperature cure of the band powdered ceramic solid particle of equal thickness because blade surface is uneven; 3, got on originally covering the coating that has applied with regard to ready alumina ceramic plate composition board, and suitably on the ceramic plate composition board, exert oneself, make the coating that is full of coating between ceramic plate and the original metal blade, make ceramic plate combination cardboard smooth simultaneously, solidified through two hours (be at that time 03 year summer 32 ℃), very firm, smooth, tore up adhesive paper or the plastic film that is attached to the ceramic plate surface in second day again.

2) be coated with the Bond of thick normal temperature cure that last layer thickness is the band powdered ceramic solid particle of 1-4 millimeter in the metal surface;
3) rely on wear-resisting ceramic plate above-mentioned Bond entirely to paste the wear-resisting metal surface of palpus, curing got final product through 1-2 hour time.
