Abstract
The invention provides underground polyvinyl chloride (PVC) tubing for coal mines, which is formed by adding a proper amount of promoter to PVC resin as the main material and extrusion molding. The invention overcomes the defects of higher specific gravity, greater task difficulty, low corrosion resistance, potential safety hazards easily caused by leakage and sparks generated by striking, high construction cost, inconvenient installation and maintenance and the like in the conventional tubing. In addition to the physical and mechanical properties of common tubing, the plastic tubing for coal mines and other high-risk environment is generally required to have the antistatic and self-extinguishing properties as well as the property that the combustion products of the plastic tubing have no hyper-toxicity. The PVC tubing of the invention for coal mines has the advantages of long service life, ageing resistance, low frictional resistance, no toxicity, corrosion resistance, impact resistance, high-pressure resistance, superior mechanical properties, good sealing performance, light weight, convenient installation construction and stable flame resistance and antistatic performance, and constitutes ideal tubing for substituting plastics for steel and optimizing resources.
Description
Technical field
The present invention relates to a kind of polychloroethylene pipes, particularly a kind of underground polyvinyl chloride tubing for coal mines and preparation method thereof.
Background technique
In the prior art, there are two big classes in traditional colliery with tubing.Wherein first class is a steel pipe, and there is the following generally acknowledged shortcoming in it: proportion is bigger, is 7 times of PE tubing, and the underground work difficulty is big; Corrosion-resistant, bump easily produces spark and has potential safety hazard; Cost height, installation and maintenance inconvenience.Second largest class is a Glass Steel Tube, though its corrosion resistance is better than steel pipe, and interface requirement height, easy to leak; Install and use simultaneously and also have many difficulties in the process; The cost height.In recent years, country widelys popularize the application plastic tube, and plastic tube develops very rapid with its excellent properties and the just continuous alternative metals of power conservation feature and other traditional material pipes.So through under the years of researches, made novel underground mine use tubing polychloroethylene pipes one by one, well overcome the defective of traditional piping material.
The model utility content
The invention provides a kind of underground polyvinyl chloride tubing for coal mines, is that main raw material adds appropriate amount of addition agent with the Corvic, through extruding and moulding, is applicable to underground mine use water supply, draining, pressure wind, whitewashing and gas extraction.The colliery is used for the contour hazardous environment in colliery with the plastic tube pipe, and the colliery except the physical and mechanical properties that should possess general plastic tube, also must have antistatic behaviour, self-extinguish ability with plastic tube, and products of combustion must not have characteristics such as hypertoxicity.This underground polyvinyl chloride tubing for coal mines has following excellent characteristics: the life-span is long, ageing-resistant, surface friction drag is little, nontoxic, corrosion-resistant, shock-resistant, anti-high pressure, mechanical property are superior, good seal performance, light weight, installation are convenient, flame retardant property and anti-static electricity property are stable, is " to mould Dai Gang ", the desirable tubing of realizing resource optimization.
Description of drawings
Fig. 1 is this underground polyvinyl chloride tubing for coal mines structural representation
Embodiment
With Corvic (1) is main raw material, adds appropriate amount of addition agent, then through extruding and moulding, makes this underground polyvinyl chloride tubing for coal mines, can be used for operations such as water supply under the coal mine, draining, pressure wind, whitewashing and gas extraction.The pipe material inner wall of making is smooth, smooth, does not have bubble, breach and tangible rill, depression etc., and appearance luster is a black even.
Except that above-mentioned mode of execution, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
Claims (2)
1, a kind of underground polyvinyl chloride tubing for coal mines is characterized in that this tubing adds appropriate amount of addition agent by Corvic (1) for main raw material, makes through extruding and moulding.
2, underground polyvinyl chloride tubing for coal mines according to claim 1, it is characterized in that every tubing both ends of the surface and axis normal, the wall thickness deviation in the same cross section of tubing is no more than 14%, and the out of roundness of tubing is not more than 5%, and the tensile strength of tubing is more than or equal to 35Mpa.
