Ailete anaerobic adhesive is a one component sealing adhesive based on the principle of oxygen inhibiting free radical polymerization. It can be used for both bonding and sealing. When the coated surface is isolated from air and can be polymerized and cured at room temperature under catalysis. The composition of anaerobic adhesive is complex, with unsaturated monomer as the main component, aromatic amines, phenols, aromatic hydrazine, peroxide and so on. In recent years, foreign anaerobic adhesive formulations continue to launch new products, favored by the machinery industry.
Anaerobe is also known as anaerobic adhesive, air repellent adhesive, thread adhesive and mechanical adhesive. It does not solidify when it comes into contact with oxygen or air. Once it is isolated from air, it polymerizes rapidly and becomes a cross-linked solid polymer. The so-called "anaerobic" refers to the use of this glue does not need oxygen. Excellent performance, heat resistance, pressure resistance, low temperature resistance, drug resistance, impact resistance, shock absorption, anti-corrosion, anti fog and other good performance. The overflow glue is not solidified and easy to remove. No solvent, low toxicity, little harm and no pollution. Widely used, sealing, locking, fixation, bonding, plugging, etc. can be stored stably, glue storage period is generally three years.
Because of its unique curing characteristics, anaerobic adhesive can be used in locking, sealing, fixing, bonding, plugging and other aspects. Anaerobic adhesive has become an indispensable liquid tool in machinery industry. It is widely used in aerospace, military industry, automobile, machinery, electronics, electrical and other industries. The traditional mechanical locking method is not ideal, but the chemical locking method is cheap and effective. If the screw is assembled after being coated with anaerobic adhesive, a strong plastic film will be formed in the thread gap after curing, so that the screw will not be loosened. The traditional method is to use rubber, asbestos, metal and other gaskets, but due to aging or corrosion will soon leak, so anaerobic adhesive is used to replace the solid gasket, which can achieve close contact after curing, making the sealing more durable.
Anaerobic adhesive is used for sealing of threaded pipe joint and threaded plug, sealing of flange matching surface, sealing of mechanical box joint surface, etc. Fixed positioning cylindrical row components, such as bearing and shaft, pulley and shaft, gear and shaft, bearing and seat hole, bushing and hole and other hole shaft combination accessories, before without exception, using hot sleeve, cold pressing and other dimensional interference method for re assembly, supplemented by keys and pins. This fixing method requires strict machining accuracy, and it is easy to loose due to wear and corrosion due to different coefficient of thermal expansion. The use of anaerobic adhesive can fill the gap, and it is firm and durable after curing. With the method of anaerobic adhesive fixation, the requirements of machining accuracy are reduced, the assembly operation is simple, the production efficiency is improved, and the energy consumption and processing cost are saved.
