Abstract
The invention discloses a bonding repair process of a high pressure plastic air duct. The process is characterized by including the following requirements: (1) an adhesive joint: a casing pipe is made of nylon, and a composite joint using butt joint and sleeve joint is adopted to be able to meet the pressure requirement of more than 0.8MPa; (2) surface treatment: surface treatment is carried out on the inner wall of the 100mm long nylon casing pipe with an inner diameter of more than 12mm, and the 50mm long outer walls respectively at two ends of a high pressure reinforced plastic air duct with an outer diameter of 12mm; (3) gluing: firstly the outer surface and section at one end of a to-be-bonded plastic pipe are brushed with a hairbrush evenly, an adhesive is applied to two ends of a fractured high pressure reinforced plastic air duct, the thickness of the adhesive layer is about 0.05-0.1mm, then the nylon casing pipe is immediately inserted into the high pressure reinforced plastic air duct's glued ends respectively to a depth of 50mm, and the nylon casing pipe is horizontally rotated to make the adhesive attach evenly; and (4) curing: under room temperature, curing can be carried out for 48h, and at a temperature of 100-120DEG C, curing needs to be performed for 2-4h. The process provided by the invention has the advantages of reasonable procedure, low cost, reasonable and coordinating parameter collocation, short time and simple operation.
Description
Technical field
The present invention relates to the vertex-gluing graph technique of a kind of high-pressure plastic airduct.
Background technology
High-pressure plastic airduct is used for industrial and mineral, agricultural and water conservancy, civil engineering, food, oil, chemical industry, the vacuum draw powder of the industries such as health, granule, conveying water, oil, chemical materials, food etc., high flow rate has the grit of abrasive forces very much, rubble, particulate, useless glass and chip, gas and liquid environment, steel plant, pit, shipyard, the conveying pipe in cement plant etc., it is used as tough protection pipe, in field irrigation, industrial and mineral, oil depot, take out sand, sandblasting, food, medical and indoor gas, powder, there is purposes widely in the fields such as dirt absorption discharge.When high-pressure plastic airduct breaks and stops transport, it is necessary to repair in time, and existing maintenance program, and its procedure arrangement is unreasonable, operation is various, the time is long, can not meet requirement, it is necessary to improved to improve performance.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide that a kind of operation is reasonable, simple to operate, the time is short, the vertex-gluing graph technique of the high-pressure plastic airduct of low cost of manufacture.
For achieving the above object, the invention provides the vertex-gluing graph technique of a kind of high-pressure plastic airduct, it is characterized in that, including following requirement:
(1) bonded joint: sleeve pipe material is nylon, adopts docking to add the composite-joint of socket, can meet the pressure requirements of more than 0.8MPa；
(2) surface treatment: be the nylon sleeve inwall more than 12mm by 100mm length, internal diameter, and the outer wall of the High Voltage each 50mm length of plastic air pipe two ends that external diameter is 12mm, coarse with emery cloth polishing, and clean up with acetone, dry；
(3) gluing: first treating that viscous plastic tube one end outer surface and section hairbrush are uniformly brushed, High Voltage plastic air pipe two ends coating adhesive in fracture, glue-line thickness about 0.05-0.1mm, immediately after High Voltage plastic air pipe gluing end is inserted nylon sleeve, the each depth 50mm in two ends, and left rotation and right rotation nylon sleeve, make glue uniform adhesion；
(4) solidify: room temperature 48h；Need at 100-120 DEG C to solidify 2-4h.
Preferred described adhesive is 101 polyurethane adhesives, and 101 polyurethane adhesives are the new photochemical plant produced in Shanghai, and this glue is good to plastic bonding power, and pliability, oil resistant, has excellent water-resistance.
The invention has the beneficial effects as follows: operation of the present invention is reasonable, each parameter collocation reasonable coordination, the time is short, simple to operate, improve and keep in repair service life, and then the loss of the time of minimizing and cost, the high-pressure plastic airduct repairing breakage with this Faville is quick, economical, and effective.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
The vertex-gluing graph technique of a kind of high-pressure plastic airduct, is characterized in that, including following requirement:
(1) bonded joint: sleeve pipe material is nylon, adopts docking to add the composite-joint of socket, can meet the pressure requirements of more than 0.8MPa；
(2) surface treatment: be the nylon sleeve inwall more than 12mm by 100mm length, internal diameter, and the outer wall of the High Voltage each 50mm length of plastic air pipe two ends that external diameter is 12mm, coarse with emery cloth polishing, and clean up with acetone, dry；
(3) gluing: first treating that viscous plastic tube one end outer surface and section hairbrush are uniformly brushed, High Voltage plastic air pipe two ends coating adhesive in fracture, glue-line thickness about 0.05-0.1mm, immediately after High Voltage plastic air pipe gluing end is inserted nylon sleeve, the each depth 50mm in two ends, and left rotation and right rotation nylon sleeve, make glue uniform adhesion；
(4) solidify: room temperature 48h；Need at 100-120 DEG C to solidify 2-4h.
Preferred described adhesive is 101 polyurethane adhesives, and 101 polyurethane adhesives are the new photochemical plant produced in Shanghai, and this glue is good to plastic bonding power, and pliability, oil resistant, has excellent water-resistance.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.All technical staff in the art, all should in the protection domain being defined in the patent claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
