Its three because described flange plate is through acidification and rubberizing, winding steel wire is fastening in the joint of flange plate and enhancement layer, has improved the decay resistance of flange plate, and strengthens greatly with the join strength of enhancement layer.
Utilize the performance parameter of the mud suction and drainage hose that technology provided by the present invention is prepared into to be:
1, wherein the water absorption rate of inner tube less than 15%;
2, resistance to low temperature is good, can be long-term used in the subzero 20 ℃ environment;
3, elongation at break is 〉=400%;
4, tensile strength 〉=12Mpa;
5, abrasion loss≤1.0cm
3
6, can reach more than 2 years working life.
Embodiment
Be described further below in conjunction with the concrete structure and the principle of the drawings and specific embodiments mud suction and drainage hose provided by the present invention.
As depicted in figs. 1 and 2, mud suction and drainage hose provided by the present invention comprises the flange plate 3 at inner glue layer 1, outer glue-line 2 and two ends, described inner glue layer 1 and outside be provided with enhancement layer 4 between the glue-line 2, enhancement layer 4 preferably adopts cord fabric to be wrapped in the outside of inner glue layer 1 in the shape of a spiral according to 52 °-57 ° angle.Cord is by warp (cord) and parallel (yarn), is interwoven in length and breadth, and its equator is to be used for connecting and to protect evenly distributed (density) of warp in cord.Like this, when in bearing, pressing load, almost all bear, can effectively bring into play the function of framework material, therefore have the compressive strength height by the cord warp, shock-resistant and advantage that flexural property is good, certainly, enhancement layer 4 also can adopt other structures.
