Abstract
The utility model provides an anti-corrosive protective layer applied to chemical equipment, which solves the problems that the processing technique of an anti-corrosive layer is complicated and the anti-corrosive layer can fall off easily under high temperature in the prior art, and is mainly applied to the anti-corrosion aspect of the equipment during a production process of a chemical product. The anti-corrosive protective layer comprises a phenolic resin impregnated graphite layer and an anti-corrosive tetrafluoroethylene coating, wherein a plurality of rectangular bulges which are uniformly distributed are arranged on the inner layer of the phenolic resin impregnated graphite layer. Having good adhesiveness with metals as well as excellent corrosion resistance and ultrahigh heat conductivity coefficient, the phenolic resin impregnated graphite layer is unlikely to fall off from metal surfaces under high temperature. Due to the bulges, the contact area between the phenolic resin impregnated graphite layer and the anti-corrosive tetrafluoroethylene coating can be increased, so that the phenolic resin impregnated graphite layer and the anti-corrosive tetrafluoroethylene coating can be adhered with each other closely, so that the firmness of the anti-corrosive tetrafluoroethylene coating is improved. In addition, the corrosion of the chemical equipment can be prevented effectively by adopting a double-layer anti-corrosive material, so that the chemical equipment is protected.
Description
Technical field
The utility model relates to the corrosion protective covering that a kind of chemical industry equipment is used, and is mainly used in the anticorrosion aspect of equipment in chemical products production process.
Background technology
In chemical products production process, gas or liquid medium are very common to the corrosion of equipment, and it destroys the metal structure of equipment, make equipment occur " run, drip, leak " phenomenon.The corrosion of chemical industry equipment, not only can cause the waste of industrial chemicals, goes back serious environment pollution, even causes a serious accident.Therefore, chemical industry equipment is anticorrosion most important.
At present, for 3 meters of following chemical industry equipments of diameter, conventionally adopt polytetrafluoroethyllining lining or anticorrosion with painting coating to protect.But when chemical industry equipment is more complicated, teflon-lined processing is a difficult problem.Although anticorrosion with painting coating is simple to operate, at high temperature, corrosion-inhibiting coating is easy to come off.Therefore, we are badly in need of the corrosion protective covering that finds a kind of chemical industry equipment simple, firm, favorable anti-corrosion effect to use.
Summary of the invention
The corrosion protective covering that the utility model provides a kind of chemical industry equipment to use, can solve that the Process Technology for Anticorrosion that prior art exists is complicated, caducous problem under high temperature, is mainly used in the anticorrosion aspect of equipment in chemical products production process.
For realizing above-mentioned requirements, the technical solution of the utility model is: the corrosion protective covering that a kind of chemical industry equipment is used, comprises resin impregnating graphite linings and tetrafluoroethene corrosion-inhibiting coating.
Described resin impregnating graphite linings internal layer is provided with some projections.
Described projection is uniformly distributed.
Described projection is rectangle projection.
Effect of the present utility model is: due to resin impregnating graphite linings and metal caking property good, and there is excellent corrosion resistance, the thermal conductivity factor of superelevation, be therefore at high temperature difficult for coming off from metal surface.Described some projections, have increased the contact area of resin impregnating graphite linings and tetrafluoroethene corrosion-inhibiting coating, make both bondings tightr, have improved the fastness of tetrafluoroethene corrosion-inhibiting coating.In addition, adopt double layer anticorrosive corrosion material protection chemical industry equipment, can more effectively prevent the corrosion of chemical industry equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: (1). resin impregnating graphite linings; (2). projection; (3). tetrafluoroethene corrosion-inhibiting coating.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, the corrosion protective covering that a kind of chemical industry equipment is used, comprises resin impregnating graphite linings (1) and tetrafluoroethene corrosion-inhibiting coating (3).
Described resin impregnating graphite linings internal layer is provided with some projections (2).
Described projection (2) is uniformly distributed.
Described projection (2) is rectangle projection.
Claims (3)
1. the double layer anticorrosive protective layer that chemical industry equipment is used, comprises internal layer heat-conducting layer and outer anticorrosive coat, and internal layer heat-conducting layer is resin impregnating graphite linings, and outer anticorrosive coat is tetrafluoroethene corrosion-inhibiting coating, and the internal layer of described internal layer heat-conducting layer is provided with some projections.
2. the double layer anticorrosive protective layer that a kind of chemical industry equipment as claimed in claim 1 is used, is characterized in that: described projection is uniformly distributed.
3. the double layer anticorrosive protective layer that a kind of chemical industry equipment as claimed in claim 1 or 2 is used, is characterized in that: described projection is rectangle projection.
