Sealant is a kind of sealing material that deforms with the shape of sealing surface and is not easy to flow. It is an adhesive used to fill the configuration gap and play a sealing role. It has the functions of anti leakage, waterproof, anti vibration, sound insulation and heat insulation. It is widely used in construction, transportation, electronic instruments and components sealing. Due to a wide range of sealant, strict operation methods, and poor competition in the market, the sealing effect of sealant is poor. Next, I will analyze the phenomenon and reasons of unqualified sealant.

The service life of construction engineering is generally more than 50 years, and the component bears large complex stress, which is directly related to the life and property safety of personnel. Structural adhesive should be used for bonding. Structural adhesive is widely used in engineering, mainly for the reinforcement, anchoring, bonding, repair of components, such as steel bonding, carbon fiber bonding, steel planting, crack reinforcement, sealing, hole repair, spike bonding, surface protection, concrete bonding, etc.

Glue machine is a kind of automatic equipment, which is used to control adhesive and other coatings and apply them on the surface of products. It is through the compressed air to send the coating into the hose, and then through the program control, the coating is dripped or coated according to the preset path.

The price of sealant is not the higher the better. There are many kinds of sealant, such as silicone sealant, polyurethane sealant, polysulfide sealant and so on. And the classification of each sealant is different, it has different classification standards, can be classified according to the base material, can also be classified according to the use, can also be classified according to the performance. But the price of sealant is not the higher the better, sealant only suitable is good, according to their own method of use, use purpose to choose the required sealant, this is good. Secondly, remind consumers to pay attention to whether the capacity of the product is sufficient when buying sealant. If the capacity of sealant is less than the marked capacity, such sealant should be eliminated first, because such enterprises have problems and the product is not much better. If the capacity is too much, it is also a problem, proving that the purchased products are not strictly controlled in the production process, and the quality may not be very good.
