Description
Technical field
The present invention relates to a kind of winding structure wall pipe.
Background technique
The China that is applied in of polyethylene spirally enwound structure-wall tubular product has the history more than 10 years, being divided into by standard GB/T 19472.2-2004 of a great variety:
First portion: polyethylene double-wall corrugated pipe material
Second portion: polyethylene spirally enwound structure-wall tubular product
Second portion is divided into " A " type and " B " type (wherein " B " type is called for short a carat pipe) again.
It is that Germany carat company is in late nineteen eighties invention in last century that carat is managed; Be characterized in utilizing poly shaping characteristic; Take special technology to form the smooth tubing of outer surface profiled inner surface; Under the situation of same materials, can reach higher ring stiffness, the production of large diameter tube material is achieved (maximum diameter can reach 4 meters) simultaneously.
Carat is managed the end of the nineties and is introduced China, is still domestic best drainage pipe at present, and proportion reaches more than 80% in key project.
Use carat advantage of pipe a lot, but certain limitation is also arranged,, as reach ring stiffness 8KN/m because the physical and chemical index of polyethylene itself causes the ring stiffness of tubing low
2With using a large amount of raw materials, also caused the waste of material when having improved cost.Particularly large diameter tubing (more than the DN1500mm) is particularly serious; And along with the attention of China to environmental protection; Demand in this field of draining to major diameter tubing is more and more, when therefore improving high-quality major diameter tubing ring stiffness price is improved not significantly and seem very important and urgent.
Summary of the invention
Goal of the invention of the present invention is in order to solve the existing low problem of polyethylene spirally enwound structure-wall tubular product ring stiffness, a kind of method of glass fiber and polyethylene composite reinforced polyethylene spirally enwound structure-wall tubing to be provided.
First kind of glass fiber and polyethylene composite reinforced polyethylene spirally enwound structure-wall tubing of the present invention is made up of support tube and reinforced layer; Said support tube is twined by the molten state ribbon and forms tubular structure; Said reinforced layer is made up of one deck bracing tube; Said bracing tube is wrapped on the molten state ribbon slit, and said bracing tube is made up of polypropylene support tube, fiberglass resin layer and polyethylene clad from inside to outside.
Second kind of glass fiber and polyethylene composite reinforced polyethylene spirally enwound structure-wall tubing of the present invention is made up of support tube and reinforced layer; Said support tube is twined by the molten state ribbon and forms tubular structure; Said reinforced layer is made up of two-layer bracing tube; The first layer bracing tube is wrapped on the molten state ribbon slit, and second layer bracing tube is wrapped between the slit of first layer bracing tube, and said bracing tube is made up of polypropylene support tube, fiberglass resin layer and polyethylene clad from inside to outside.
The third glass fiber and polyethylene composite reinforced polyethylene spirally enwound structure-wall tubing of the present invention is made up of support tube and reinforced layer; Said support tube is twined by the molten state ribbon and forms tubular structure; Said reinforced layer is made up of the multilayer bracing tube; The first layer bracing tube is wrapped on the molten state ribbon slit, and other layers bracing tube is wrapped between the slit of its adjacent layer bracing tube, and said bracing tube is made up of polypropylene support tube, fiberglass resin layer and polyethylene clad from inside to outside.
The material of above-mentioned said molten state ribbon is a polyethylene; The above-mentioned fiberglass resin layer of stating is made up of polyethylene and staple glass fibre, and the weight percentage of staple glass fibre is 15%～18% in the fiberglass resin layer, and the diameter of said staple glass fibre is 0.10mm～0.18mm, and length is 6mm～25mm.
Caliber of the present invention is that the ring stiffness of the glass fiber and polyethylene composite reinforced polyethylene spirally enwound structure-wall tubing of DN2000mm is 8.2KN/m
2(same model employing polyethylene is that the ring stiffness of raw material tubing is merely 3.8KN/m
2), glass fiber and polyethylene composite reinforced polyethylene spirally enwound structure-wall tubing of the present invention has improved the ring stiffness of tubing when keeping carat pipe performance, and particularly evident to major diameter tubing effect especially, ring stiffness improves 2～3 times under the prerequisite of same materials.
