1 Application of bonding materials in petrochemical machinery
1.1 Application of adhesive in petrochemical machinery
In the process of petrochemical production, bonding materials mainly play different roles, such as filling mechanical metal materials, improving the corrosion resistance of mechanical equipment, emergency repair of mechanical equipment, etc. According to the chemical composition, different adhesives can be used in different mechanical equipment. For example, in the process of repairing the easily damaged area of mechanical equipment, adhesive can be used to repair the mechanical equipment. The repair of mechanical equipment is relatively simple. First, the surface of worn mechanical equipment shall be treated to ensure that the cleanliness of the mechanical surface meets the actual repair requirements. Apply the repair agent to the treated surface and grind the cured repair agent to a standard height.
At the same time, the adhesive is applied to the corrosion repair of petrochemical machinery and equipment. Due to the different areas and depths of the corroded parts of the equipment, polymer bonding materials can be selected to repair the equipment surface and prolong the service life of the equipment.

1.2 Application of anaerobic adhesive in petrochemical machinery
The anaerobic adhesive is an early polymer adhesive used in the petrochemical industry. It first appeared in the 1950s. It can be effectively used in the bonding, fixing, and sealing of petrochemical machinery and equipment. Affected by the composition and year of anaerobic glue, the application range of different anaerobic glue is different. Because anaerobic glue will not react in the air, it can be stored in an indoor environment for a long time. At the same time, the anaerobic adhesive can solidify rapidly in an anaerobic environment, so it can effectively improve the maintenance efficiency of petrochemical machinery and equipment. At present, commonly used anaerobic adhesives are mainly divided into acrylic acid, diethylpropion acid, and other types. Professional anaerobic glue for bolts.
Under the action of peroxide, the anaerobic machine can produce a free radical reaction in the bonding and sealing process of petrochemical mechanical equipment, so it can be more suitable for the anti loosening treatment of bolts in mechanical equipment. The anaerobic adhesive is applied to the bolt. During the tightening process, the air between the bolt and nut is squeezed and discharged, so that the anaerobic adhesive can give full play to its due curing effect, enhance the tightness between the bolt and nut, and fundamentally improve the applicability of mechanical equipment to the complex production environment.
2 Application of sealing materials in petrochemical machinery
In the process of petrochemical production, the mechanical equipment required for production has the structure of rigid components bonded to each other, so it is necessary to use sealing materials to treat the rigid components of the petrochemical industry. Specifically, the liquid gasket is applied to the mechanical sealing process, the liquid adhesive is applied to the surface of metal mechanical materials, and the coating with uniformity and elasticity is formed after drying and curing treatment. After the liquid is applied to the surface of the equipment, the elasticity of the gasket will not increase, so the adhesive will not fill the gap in the metal parts.
3 Application prospect analysis of bonding and sealing materials in petrochemical machinery
At present, there are many kinds of bonding and plugging materials used in petrochemical machinery with different properties. At present, bonding and sealing materials tend to be polymer-based. By continuously optimizing polymer bonding and sealing technology, we can effectively improve the operation quality and efficiency of petrochemical machinery and equipment. Due to the short time of applying bonding and sealing materials in China, it is necessary to actively introduce advanced bonding and sealing materials in the future development process and strengthen the bonding of new bonding and sealing materials. Promote the rapid development of the polymer industry, closely combine polymer technology with the production of bonding and sealing materials, and ensure that the produced bonding and sealing materials can better meet the production requirements of the petrochemical industry.
4 Application cases of bonding and sealing materials in petrochemical machinery
During the sealing process of bonding and sealing materials in petrochemical machinery and equipment, it is necessary to select appropriate sealing methods according to different leakage conditions of the equipment. Specifically, the plugging methods of petrochemical machinery and equipment are mainly divided into two types: static plugging and pressurized plugging. Among them, the sealing technology under pressure mainly uses polymer sealing materials and sealing technology to block the leaking mechanical equipment and leaking pipeline without stopping the operation of the equipment, to fundamentally avoid leakage. At the same time, the sealing technology under pressure will not affect the normal operation of production machinery and equipment in the process of practical application, and the surface sealing material is very easy to be removed during equipment maintenance.
The materials used in the plugging process of mechanical equipment shall be properly selected according to the properties of equipment medium, temperature, pressure, and other factors. To meet the requirements of petrochemical production, specially prepared plugging materials can also be used to control the amount of filler.
5 Concluding remarks
In a word, bonding and sealing materials directly affect the production level of the petrochemical industry. To fundamentally prolong the operation life of petrochemical machinery and equipment, more advanced bonding and sealing materials should be selected in combination with the operation characteristics and requirements of the equipment . Actively introduce more advanced production processes, strengthen the research on polymer bonding and sealing materials, ensure that polymer bonding and sealing materials can play an important role in ensuring the mechanical production level of the petrochemical industry, and promote the petrochemical industry to move in a better direction.See more: Buy silicone rubber products
