Description
Technical field
The present invention relates to the outer adhering resin layer bonding strength method of testing of a kind of steel wire mesh frame plastic composite tube material.
Background technology
Steel wire mesh frame polyethylene compound pipe is the one novel high-tech environmental-protecting chemical tubing of domestic rise nearly ten years.It is for skeleton with the reticulate texture being wound around braiding formation about high strength coppered steel wire, take high density polyethylene as matrix material (tygon is PE100 level special material for pipeline), utilize modified poly ethylene---adhering resin, on a production line by continuously, gradation extrusion molding compound and withstand voltage, the internal and external anti-corrosive chemical building material of new generation that are formed.This product specification is φ 63 ~ φ 630mm, is widely used in the industries such as municipal plumbing, petrochemical complex, electric power, coal and mine.
Although peel strength reflects the bonding stability of composite bed to a certain extent, the result of peel strength test is mean value, just from macroscopically reflecting fastness bonding between composite bed.The stability of industry standard to composite bed separately has regulation, namely in CJT/189-2007, requirement has been done separately to the hydrostatic stability of composite bed, and method of testing is given in industry standard, if but according to the method for testing in industry standard, need to waste a large amount of electrothermal smelting tubes, cost is too high, commercially also there is relevant fixture to replace electrothermal smelting tube at present, but all there are two shortcomings, one, be that sealing property is unstable, two, better can better not carry out pressure test to composite bed, effect is unsatisfactory.
Tubing is in use destroyed, and always from the weakest any or a region, then slowly expands overall destruction to, finally causes tubing to burst.Only judge whether tubing can channeling water be inadequate according to peel strength test result from this point of view, also whether channeling water must can do experiment test separately to tubing, that is to say and require to do in industry standard, in order to the cost of this test and don't too much increase test body can be carried out, the method of testing that can specify rower is carried out equivalence and is replaced, to meet the validity of test result and minimizing of testing cost.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of preparation cost low and can at any time to steel wire mesh frame plastic composite tube material method of testing and the fixture of properties of product and quality monitoring and control.
When meeting test request, adopt the test fixture that can reuse to connect to replace electrothermal smelting tube, the test fixture developed should have: ensure that tube end face and pipe material inner wall bear equal hydraulic pressure; Take radial surface to seal, can adopt multiple tracks rubber seal and raw material band with the use of, water-tight to guarantee; For composite bed stability test, obtain the result of equivalence test, meet the requirement of the outer adhering resin layer bonding strength test of steel wire mesh frame plastic composite tube material.
First object of the present invention is achieved in that the outer adhering resin layer bonding strength method of testing of a kind of steel wire mesh frame plastic composite tube material, it is characterized in that comprising the following steps:
(1) preparation comprises the test fixture of clamp base 1, rubber seal 2, coupling bolt 3, sealing clamp 4, fastening claw 5, sealing clamp holding screw 7, end face back-up block 10 composition, and described clamp base is provided with medium flowing hole; The medial surface of described fastening claw 5 is provided with sawtooth claw;
(2) pressure testing tubing two ends to be tested are distinguished test fixture prepared by installation steps (1), fastening claw 5 cover is stuck on the periphery of pressure testing tubing end, clamp base 1 is nested with by fastening claw 5, rubber seal 2, sealing clamp 4 pipe end being arranged on pressure testing tubing 6, rubber seal 2 is arranged between clamp base 1 and pressure testing tubing 6, sealing clamp 4 is arranged between clamp base 1 and fastening claw 5, rubber seal 2 is compressed in clamp base, between pressure testing tubing and sealing clamp, fastening claw 5 is connected and fixed by fastening bolt and clamp base 1;
(3) step (2) being installed the pressure testing tubing of test fixture, take water as medium, tests the peel strength of pressure testing tubing and compressive resistance.
Second object of the present invention realizes like this, a kind of steel wire mesh frame plastic composite tube material test fixture, it is characterized in that being provided with clamp base 1, rubber seal 2, sealing clamp 4, fastening claw 5, fastening claw 5 cover is stuck on the periphery of pressure testing tubing end, clamp base 1 is by fastening claw 5, rubber seal 2, sealing clamp 4 is nested with the pipe end being arranged on pressure testing tubing 6, rubber seal 2 is arranged between clamp base 1 and pressure testing tubing 6, sealing clamp 4 is arranged between clamp base 1 and fastening claw 5, rubber seal 2 is compressed in clamp base, between pressure testing tubing and sealing clamp, fastening claw 5 is connected and fixed by fastening bolt and clamp base 1.
Described clamp base 1 is provided with the holding screw 7 of fit sealing pressing plate.
The face that described fastening claw 5 contacts with pressure testing tubing 6 is provided with the sawtooth claw strengthening friction factor.
Described clamp base is provided with medium flowing hole (pressure water inlet and exhausr port).
Test mode of the present invention is different from traditional pipeline pressure method of testing, especially specific aim is had more to the withstand voltage properties inspection of compound tubing, in traditional voltage withstanding test fixture, what test is all then by stamper pressure testing by inner hole of pipe sealing, his sealing means is blocked from inwall by pipe, form radial seal, a kind of mode is also had to be sealed end face by the distortion of end face crush seal circle in addition, in test process, the pressure born after when butt-end packing is almost nil.In industry standard, require regulation to voltage-withstand test, the peel strength between requiring tubing composite bed and compressive resistance are tested.In order to improve the quality of products and ensure stable performance, the present invention proposes a brand-new test theory and test fixture, this fixture only by radial seal to tube end face blow-by, make in test process tube end face and pipe material inner wall bear equal pressure, so just judge that tube end face can or can not channeling water when bearing same equal pressure, and better judge that whether tubing is qualified.The present invention, effectively to the withstand voltage properties Inspect and control of steel wire mesh frame plastic composite tube material, makes product withstand voltage more stable.The present invention adopts common iron to process, and sealing means adopts rubber seal to carry out radial seal, makes this fixture more practical and durable.Equipment set low cost of manufacture, but has qualitative leap to the quality improving tubing itself, to be easy to accept by numerous enterprises.
The inventive method is easy, and apparatus structure is simple, easy to operate.Relative to prior art, effect of the present invention and advantage are:
