Description

Glass fiber reinforced plastic sand inclusion pipe

Technical Field

The utility model belongs to a material conveying pipeline specifically is a glass fiber reinforced plastic sand inclusion pipe.

Background

The glass fiber reinforced sand inclusion pipe is a novel composite material pipeline which is made by taking resin as a base material, taking glass fiber and products thereof as reinforcing materials and taking quartz sand as a filling material, and has the advantages of high corrosion resistance, compactness, water resistance, high strength, light weight, large conveying flow, convenience in installation, long service life and the like, so that the glass fiber reinforced sand inclusion pipe is widely applied to drainage pipes in the chemical industry and urban sewage drainage engineering.

Present widely used glass fiber reinforcement sand inclusion pipe all is simple adoption glass fiber, resin and quartz sand mix and make, though make tubular product have certain structural strength and corrosion resisting property like this, but its toughness is relatively poor, easily cracked when receiving the impact again, its tensile shear strength is not enough in some special environment in addition, has restricted the popularization and application of sand inclusion pipe, consequently need the not enough of the sand inclusion pipe that a toughness is good to remedy current sand inclusion pipe urgently to improve its application scope.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a glass fiber reinforced plastic sand inclusion pipe to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a glass fiber reinforced plastic sand inclusion pipe comprises a framework, wherein an adhesive layer is coated on the framework, a structural layer is arranged on the outer side of the adhesive layer, and an outer layer is arranged on the outer side of the structural layer; the inner side of the adhesive layer is provided with an inner layer.

As a further aspect of the present invention: the framework is a tubular steel wire mesh formed by mutually and alternately weaving a plurality of high-strength steel wires.

As a further aspect of the present invention: the structural layer comprises a mortar layer and a winding layer, the mortar layer is arranged on the outer side of the adhesive layer, and the winding layer is arranged on the outer side of the mortar layer.

As a further aspect of the present invention: the mortar layer is formed by mixing and injection molding of glass fiber and bisphenol A epoxy resin.

As a further aspect of the present invention: the inlayer includes barrier layer and anticorrosive coating, and the barrier layer sets up the inboard at the gluing layer, and the anticorrosive coating sets up the inboard at the barrier layer.

As a further aspect of the present invention: the anticorrosive coating is formed by injection molding of phenolic resin.

Compared with the prior art, the utility model discloses novel structure, it is durable, through setting up the skeleton, increase the toughness and the structural strength of pressing from both sides the sand pipe, avoid pressing from both sides the sand pipe in the transportation, installation and use are cracked because of receiving the impact, improve the application range and the life-span of pressing from both sides the sand pipe, through setting up the gluing layer, can be with structural layer and nexine adhesion on the skeleton, improve the structure compactness between each constitution layer of pressing from both sides the sand pipe, avoid pressing from both sides each layer of sand pipe and break away from and damage, through setting up anticorrosive coating and barrier, the leakproofness and the durability of pressing from both sides the sand pipe have been increased, make simultaneously press from both sides the sand pipe and can be used for carrying various corrosivity and the strong liquid of pollution nature.
