CN105754502A - Bonding repair process of rubber sealing ring - Google Patents

Abstract

The invention discloses a bonding repair process of a rubber sealing ring. The process is characterized by including the requirements of: 1) an adhesive: a cyanoacrylate 496 glue is adopted as the adhesive, and the shear strength of the adhesive reaches 16.7Mpa; 2) bonding process: (1) an O-type ring notch: in order to ensure the smoothness of the O-type ring notch, stuffing a to-be-repaired rubber ring strip into a corresponding diameter hole on a fixture, using a sharp blade to perform cutting along the fixture wall in a direction perpendicular to the axial direction of the round strip to obtain a 90-degree plane notch; (2) surface treatment: polishing the notch surface slightly with abrasive cloth, and wiping the notch surface clean with acetone; (3) bonding: coating two bonding surfaces both with a thin layer of 496 glue, putting the strip into a V-shaped groove on the fixture to perform positioning, carrying out aligning bonding and tight squeezing, and necessarily applying a layer of mould release agent or laying a layer of polyethylene film in the V-shaped groove; and (4) curing time: performing preliminary curing for 10-20s, and then conducting curing for 2h, thus being able to put the rubber seal ring into use. 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

A kind of vertex-gluing graph technique of rubber seal

Technical field

The present invention relates to the vertex-gluing graph technique of a kind of rubber seal.

Background technology

Maintenance of equipment is frequently encountered by O type rubber seal damage, if be normally carried out affecting production without suitable spare part, especially for common nesperene washers such as fourth fat rubber, neoprenes, existing maintenance program, and its procedure arrangement is unreasonable, operation is various, 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 rubber seal of low cost of manufacture.

For achieving the above object, the invention provides the vertex-gluing graph technique of a kind of rubber seal, it is characterized in that, including following requirement:

(1) adhesive: adopting 496 glue of cyanoacrylate, its shear strength reaches 16.7Mpa；

(2) technique for sticking: 1. O otch: smooth in order to ensure O otch, fills on fixture in the hole of respective diameters by rubber ring bar to be repaired, axially imposes uniformity without examining individual cases down along holder wall vertical circular bar with fast blade, can cut Plane Notch in 90 °；2. surface treatment: cut surface can be beaten slightly close with emery cloth, and uses acetone wiped clean；3. bonding: two gluing of surfaces are all coated with a thin layer 496 glue, it is placed on above fixture and V-groove positions, align bonding and jam-packed, must coating releasing agent or pad layer of polyethylene thin film in described V-groove；4. 10-20s hardening time can primary solidification, then can come into operation after 2h.

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, improves and keeps in repair service life, and then the loss of the time of minimizing and cost, repaiies O with this Faville 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 rubber seal, is characterized in that, including following requirement:

(1) adhesive: adopting 496 glue of cyanoacrylate, its shear strength reaches 16.7Mpa；

(2) technique for sticking: 1. O otch: smooth in order to ensure O otch, fills on fixture in the hole of respective diameters by rubber ring bar to be repaired, axially imposes uniformity without examining individual cases down along holder wall vertical circular bar with fast blade, can cut Plane Notch in 90 °；2. surface treatment: cut surface can be beaten slightly close with emery cloth, and uses acetone wiped clean；3. bonding: two gluing of surfaces are all coated with a thin layer 496 glue, it is placed on above fixture and V-groove positions, align bonding and jam-packed, must coating releasing agent or pad layer of polyethylene thin film in described V-groove；4. 10-20s hardening time can primary solidification, then can come into operation after 2h.

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.
