Detailed Description
In the following examples, unless otherwise specified, the outer and inner edges are defined as inner and outer edges in relative relation, and refer to the center of the sheath or the wear-resistant ceramic layer being relatively far from the outer edge and the center of the sheath or the wear-resistant ceramic layer being relatively close to the inner edge.
Examples are shown in fig. 1 and 2: the multi-material composite guard board for the slurry pump comprises a rubber layer 10, a wear-resistant ceramic layer 20 and a metal framework 30. A plurality of threaded holes 31 are formed in one side surface of the metal skeleton 30, and are used for screwing in screws to fix the guard plate at a required position.

Typically, the annular groove 32 is filled with an adhesive, which may be resin, rubber or metal (the same applies below), so that the metal skeleton 30 is preferably fixed after solidification. Meanwhile, the wear-resistant ceramic layer 20 and the metal skeleton 30 are embedded in the rubber layer 10 by a vulcanization injection molding process. Generally, there is a gap of 2-3mm between the outer edge of the wear resistant ceramic layer 20 and the corresponding edge of the annular groove 32 to avoid direct contact. Thus, not only the metal framework 30 and the wear-resistant ceramic layer 20 are combined well, but also the elasticity of rubber and the wear resistance of ceramic are organically combined together, and the service life of the guard plate is effectively prolonged.
Optimizing:
as shown in connection with fig. 3 to 5, the wear-resistant ceramic layer 20 includes an inner ring 2a and an outer ring 2b. Obviously, the outer ring 2b is sleeved outside the inner ring 2 a.

And, an adhesive is injected between the inner unit positioning open slot 2a11 and the inner unit positioning open slot 2a11 corresponding thereto. Likewise, the outer ring 2b is uniformly divided into an even number of outer unit sections 2b1, for example, 8 sections each having a fan shape. And the connecting edge of the outer unit section 2b1 is provided with outer unit positioning open slots 2b11, and the outer unit positioning open slots 2b11 on the adjacent outer unit sections 2b1 correspond to each other in pairs. By connecting edges is meant edges of adjacent 2 outer cell segments 2b1 that are close together. And, an adhesive is injected between the outer unit positioning open groove 2b11 and the outer unit positioning open groove 2b11 corresponding thereto. That is, the inner ring 2a and the outer ring 2b are also divided into a plurality of sections, and the solidified adhesive is clamped in the circular hole formed by the corresponding inner unit positioning open slot 2a11 and the circular hole formed by the corresponding outer unit positioning open slot 2b11, so that the processing difficulty is further reduced, and the solidified adhesive enables the inner ring 2a and the outer ring 2b which are designed in a split manner to be combined more tightly.
