Abstract
The utility model relates to a PVC compound mine pipe, which has the advantages of static electricity resistance, erosion resistance, low cost and secure use. The technical proposal is that the mine pipe is formed by the co-extrusion of a rigid polythene outer layer modified by antistatic agent and a ductility-improved PVC inner layer. The outer layer and the inner layer are combined together firmly and an antistatic agent modified compound pipe the inside of which is an empty cavity is formed. The utility model has simple structure and convenient installation and use, which can improve the advantages of sound insulation, heat insulation, shockproof performance, light weight and the like for a solid wall tubular product, in particular to the shockproof performance, erosion resistance and heat-resistant quality; especially, an inner wall adopts the inner layer formed by the ductility-improved PVC so that the ductility of the inner layer is improved greatly and the antistatic agent and flame retardant effect is good. The utility model has the advantages of long service life, no poison, good security and extensive application range, which is the innovation of the mine pipe and has distinct economic and social benefit.
Description
One, technical field
The utility model relates to plastic tube, and particularly a kind of PVC grandidierite is with managing.
Two, background technique
Envionmental humidity height under the coal mine, and have acid water, corrosive gas and gas cause gas explosion accident because of electrostatic accumulation sometimes.In the prior art, there are metal tube, Glass Steel Tube in traditional colliery with tubing, but the shortcoming that these two kinds of tubing all exist some to generally acknowledge: bigger as proportion, the underground work difficulty is big; Corrosion-resistant, bump easily produce spark and have potential safety hazard; Cost height, installation and maintenance inconvenience; The interface requirement height, easy to leak etc.In recent years, country widelys popularize the application plastic tube, develops very rapid.Tool has following excellent characteristics: antistatic, fire-retardant; Nontoxic, corrosion-resistant, anti-high pressure; Light weight, easily installation are " to mould Dai Gang ", the desirable tubing of realizing resource optimization.The colliery is used for the contour hazardous environment in colliery with the plastic tube pipe, except the physical and mechanical properties that should possess general plastic tube, also must have antistatic behaviour, self-extinguish ability, and products of combustion must not have hypertoxicity.Though existing Vybak mining pipes has antistatic behaviour, characteristics such as self-extinguish ability, its specific (special) requirements applications in the down-hole is restricted.Therefore, the improvement of a mining pipe and innovation technical problem being in the industry to be concerned about.
Three, model utility content
At above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model just provides a kind of PVC grandidierite with managing, can effectively solve antistatic, corrosion-resistant, reduce cost, problem safe in utilization, the technological scheme of its solution is, outer and the improved PVC internal layer of the toughness double-layer coextrusion by the hard polyethylene of anti-static agent modification, in making, outer strong bonded is an one, constituting inside is the antistatic modified compound body of cavity, the utility model is simple in structure, and is easy to install, not only has the sound insulation of general solid wall pipe material, heat insulation, shockproof, and the advantage of aspect such as light weight, and in shock resistance, corrosion resistance, the resistance to heat aspect particularly improves, particularly inwall adopts the improved PVC of toughness to make internal layer, and internal layer toughness is greatly improved, and is antistatic, good flame retardation effect, long service life, nontoxic, safety, wide application, be an innovation on the mining pipe, remarkable economical and social benefit are arranged.
Four, description of drawings
Accompanying drawing is a structural profile plan view of the present utility model.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Shown in accompanying drawing, the utility model is by the hard polyethylene outer 1 and improved PVC internal layer 2 double-layer coextrusions of toughness of anti-static agent modification, and making inside and outside layer strong bonded is one, and constituting inside is the antistatic modified compound body of cavity 3.
Said outer 1 is long-round-shape or the rectangular cavity body of being made by the hard polyethylene of anti-static agent modification; Said internal layer 2 is long-round-shape or rectangular cavity body of being made by the improved PVC of toughness; The thickness of internal layer is not less than outer field thickness.During production, internal layer 2 and outer 1 can adopt the once-through of double-layer coextrusion technology, and strong bonded is as a whole.
The water supply under coal mine of the utility model effective application, draining, pressure wind, whitewash and draw out methane the spy Not the use as drinking-water pipe, gas under coal mine pipe under ventilation duct, the coal mine under the coal mine, more Have outstanding effect, the utility model has been compared with existing technology following good effect (advantage): its surface Resistance is very little, is difficult for producing static, simultaneously, owing to adopted the internal layer of toughness modification, has overcome common poly-Vinyl chloride tubing corrosion resistance difference and heat resistance difference and meet the to impact shortcoming such as easily break, of the present utility model excellent Point also is: technology is simple, produces easily, need not to increase novel device, except possessing common polyvinyl chloride ore deposit Outside the advantage with tubing, also improved the advantage of the aspects such as its original sound insulation, heat insulation and light weight, peace Load connects simple and convenient, can use special-purpose glue to connect, and is safer.
Claims (4)
1, a kind of PVC grandidierite is with managing, it is characterized in that, by the hard polyethylene skin (1) and the improved PVC internal layer of toughness (2) double-layer coextrusion of anti-static agent modification, making inside and outside layer strong bonded is one, and constituting inside is the antistatic modified compound body of cavity (3).
2, PVC grandidierite according to claim 1 is characterized in that with pipe said skin (1) is long-round-shape or the rectangular cavity body of being made by the hard polyethylene of anti-static agent modification.
