The glue on the market is called "adhesive" in the industrial field. There are many kinds of glue with different performance. Many consumers may be dazzled and don't know how to start. Today, let me help you to figure out the types and uses of various glues, so that you can quickly understand the glue and buy without stepping on the pit.
Instant drying glue: most commonly used
The main component of instant drying adhesive is cyanoacrylate adhesive, which has good bonding ability to most materials and is most suitable for emergency repair and assembly positioning. It is widely used in electronic components, household appliances and other aspects. Its curing speed is very fast, and it can be completed in a few seconds. It is a common choice for families and enterprises.
Anaerobic adhesive: small helper for part locking
Anaerobic adhesive refers to the adhesive that will solidify in the absence of oxygen/air, and is generally used for bonding metal to metal. Anaerobic adhesive can be used for thread locking, pipe sealing, plane sealing, and parts fixing. According to different use scenarios, anaerobic adhesives are often divided into four types: thread locking adhesive, pipe thread sealant, retaining adhesive and flange seal.
1. Thread sealant
As the name implies, screw thread sealant is an important locking tool used to avoid mechanical thread looseness. The machine will inevitably be worn and loose in the daily operation. The traditional thread locking cannot avoid the vibration problem caused by the existence of clearance, and the screw thread sealant is born to solve this problem.
2. Retaining glue
Cylindrical assembly of shaft and shaft sleeve has always been a classic combination of traditional mechanical assembly methods, which tests the processing accuracy and interference control of shaft assemblies. In addition, there will be a lot of clearance between the shaft and the kit, which may cause fretting corrosion and wear, leaving a potential safety hazard.
Fixing glue is a kind of glue to solve this problem. It can fill the gaps between parts to achieve maximum load transmission capacity and uniform stress distribution, and eliminate fretting corrosion. Loctite retaining adhesive can effectively fill the gap, evenly distribute the load, and its high shear strength can enhance or even replace the traditional mechanical assembly method.
3. Flange (plane) seal
Flange is the most common connection method for connecting pipes, pipe fittings, valves, instruments and equipment in petrochemical plants. It has the advantages of convenient disassembly and no hot work. However, flange sealing is achieved through the joint action of flange, bolt and gasket, and any problem in any part will cause leakage and loss.
Structural adhesive: commonly used in industry
Structural adhesive refers to a kind of adhesive with high strength, large load, aging resistance, fatigue resistance and corrosion resistance. Structural adhesive has stable performance and is widely used as adhesive for bonding structural parts with strong strength.
UV curing adhesive
The UV curing adhesive can be cured rapidly under the irradiation of appropriate wavelength and light intensity, with high transparency and high adhesion, and can significantly reduce the process cost.
UV curable adhesives have a wide range of applications. In addition to rapid bonding, fixation and sealing of transparent materials, they can also be used for rapid assembly of medical consumables, and fixation or encapsulation of electronic components.
