Wave-like concaveconvex structure, the depressed area second casting of the wavy concaveconvex structure or gluing more flexible cut can be tight with polyurethane
Other polyurethane fillers of close fusion, so as to reduce building up for compass screen surface material, the utility model composite screen mesh upper strata ripple
Wave-like concaveconvex structure mainly resists material impact, even if because the cutting of sharp material produces miniature wound, but upper strata surge layer is not
The stretching of compass screen surface stretching basic unit is participated in, so these miniature wounds would not produce the expansion under high frequency stretching action, so as to extend
Life-span of screen cloth；Above-mentioned composite screen mesh can be made up of two kinds of processing methods, and the first is that band sieve aperture is poured into a mould, the party
The advantages of method, is sieve aperture forming, is adapted to produce in enormous quantities；Second method is poured into a mould without sieve aperture, pour rear punching or
Person's Water Cutting mode obtains sieve aperture, is only to need a kind of mould the advantages of this method, shortcoming is that punching technology pitch of holes is difficult to
To strict guarantee, and the Water Cutting cost of technology is higher, is adapted to small lot to produce in this way.
The tensile strength of the polyurethane stretching basic unit of the utility model composite screen mesh is higher, second casting or gluing poly- ammonia
The extensibility of the relative stretching basic unit of the extensibility of ester filler is higher and the wearability of polyurethane filler is superior.
In summary, composite screen mesh of the present utility model has the advantages of simple in construction；Composite screen mesh of the present utility model
Service life is grown, and extends the replacement cycle of screen cloth, reduces the parking maintenance cost of manufacturing enterprise；Answered using the utility model
The relaxation sieve for closing screen cloth has large increase to high intensity material screening ability.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
