Abstract
The magnetic PE pipe is made of PE plastic containing magnetic ferrite powder. It is produced with magnetic ferrite powder 17-27 wt%, PE plastic 70-80 wt%, silane coupler 1-2 wt%, and plasticizer 1-2 wt%, and through mixing magnetic ferrite powder silane coupler and alcohol in a stirrer; mixing with PE plastic powder and plasticizer; pelletizing in a pelletizer; mixing with PE plastic grain in a stirrer; drying and extruding through an extruder to obtain pipe; and final magnetizing in a magnetizer. The magnetic PE pipe possesses permanent magnetism, and after it is laid underground, it may be detected with magnetic detecting instrument for convenient construction.
Description
Technical field
The present invention relates to pipeline tubing, particularly a kind of PE plastic tube, and the manufacture method of this plastic tube.
Background technique
PE (polyethylene) pipe since corrosion-resistant, easy construction, advantage such as with low cost have a wide range of applications in municipal water supply, gas transmission and distribution field.Can't be detected by instrument owing to being layed in underground plastic article at present, can only set up mark, in urban construction, easily be damaged, cause and leak even the gas leakage incident, affect the people's life and life safety on ground.
In order to address this problem, be around plastic pipe, to lay a flat copper spike silk at present, utilize metal detector to survey.But wire is embedded in the soil, and is perishable, grown service time just not have the detection effect, and can not indicate the diameter of pipeline, thereby inconvenience promoted.
Summary of the invention
The solution of the present invention is: a kind of magnetic PE pipe is to contain ferromagnetic oxide powder in the PE base-material, and its quality than ratio is: ferromagnetic oxide powder 17-27%, plastics 70-80%, silane coupler 1-2%, plasticizing agent 1-2%.
Its manufacture method is: earlier ferromagnetic oxide powder, silane coupler and alcohol are put into stirrer for mixing; mix back adding PE plastic powders and plasticizing agent by the tablet machine granulation; the well back material adding of granulation PE plastic granule is put into stirrer and is evenly stirred; it is dry that raw material after stirring is put into baking oven; extrude production tubing by extruder; and cutting into gage length, last tubing magnetizes by magnetizer.
Advantage of the present invention is: owing to having added ferromagnetic oxide powder in the tubing and it being magnetized, make tubing have permanent magnetism, pipe laying is underground, available magnetic detecting instrument is surveyed, and tubing integral body has magnetic, and the detectable diameter that goes out pipeline is for construction provides convenience.
Embodiment
The invention will be further described according to embodiment below.
Embodiment's magnetic PE pipe, employing PE is a base-material, mixes ferromagnetic oxide powder and adopts Fe
2O
3, the mass ratio of each component is: ferromagnetic oxide powder 22%, plastics 76%, silane coupler 1%, plasticizing agent 1%.
Manufacturing process is:
1. ferromagnetic oxide powder Fe just
2O
3, silane coupler and alcohol puts into stirrer for mixing.Wherein the silane coupler ratio is 1%, can improve the cohesiveencess of organic and inorganic material interface, and alcohol adopts an amount of, plays diluting effect.
2. pass through the tablet machine granulation after in mixed material, adding PE plastic powders and plasticizing agent.
The mixture volume ratio that flow process 1 makes is 45%, plastic powders 54%, and plasticizing agent 1%, plasticizing agent are dibutyl phthalate.
Granulation well back material 1: 1 by volume add the PE plastic granule and put into stirrer and evenly stir.
4. it is dry that the raw material after will stirring is put into baking oven; Drying temperature is 80 ℃, and the time is 4-5 hour.
5. extrude production tubing by extruder, and cut into gage length.
6. tubing is magnetized by magnetizer.
7. test package.
During detection, adopt RD135 magnetic detecting instrument, this magnetic detecting instrument has adopted the magnetic field balancing technique, can detect the magnetic field around the magnetic bodies, when survey meter during near the magnetic PE pipe road, just obtain peak response, thereby can determine size, shape and the position of pipeline, this equipment is a megnetic instrument, detection be the magnetic of object, so it responds to magnetic metal, and be not subjected to copper, the influence of nonmagnetic metal such as aluminium.
Claims (2)
1. a magnetic PE pipe is characterized in that containing ferromagnetic oxide powder in the PE base-material, and its quality than ratio is: ferromagnetic oxide powder 17-27%, plastics 70-80%, silane coupler 1-2%, plasticizing agent 1-2%.
2. magnetic PE pipe as claimed in claim 1; its manufacture method is: earlier ferromagnetic oxide powder, silane coupler and alcohol are put into stirrer for mixing; mix back adding PE plastic powders and plasticizing agent by the tablet machine granulation; the well back material adding of granulation PE plastic granule is put into stirrer and is evenly stirred; it is dry that raw material after stirring is put into baking oven; extrude production tubing by extruder, and cut into gage length, last tubing magnetizes by magnetizer.
