Sealant Is Used to Keep Our Safety
Published on October 17 2012
The fundamental characteristics of sealant
Sealant is usually based on dry or non-dry dope such as, asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber, coordinated with talcum powder, caraclazyte, carbon black, titanium dioxide and asbestos, and then mixed with plasticizer, solvent, curing agent and accelerator. It can be divided into elastic sealant, liquid sealing gasket and waterproof sealant which are widely used in the industry of building, transportation, electronic instruments. And it possesses the following features: 1. excellent caulking, stable storage, non-toxic or harmless. 2. The low hyposmosis of liquid, gas and other media. 3. Strong resistance to flexible movement, shifting and transformation. 4. Enough ability to bear pressure, and so on.
The advantages of sealant
The performance of sealant directly affects the package effect, the storage and life of products, even the reputation of products, and it will make sealant an important part in the field of package. According to the form and use method of sealant material, it can be roughly divided into gasket sealing, seal tape sealing and colloid sealing. All of these can prevent liquid from leaking, oxygen, wet air and peculiar smell from entering, and anti counterfeit and sham products. And window sealant is a kind of technology appeared in the recent years, which concludes point sealing by hot melt adhesive or pressure-sensitive adhesive. Once the package is torn down, it cannot be repaired in order to prevent the sham products, and protect costumer's benefits.
Construction method
1. Clean the repaired parts, wipe of greasy dirt and dust. 2. Set the width of joint filling affixed to masking tapes, making sure it smooth and good-looking. 3. Extrude the glue gun smoothly and construct in 45 degree angle and add sealant to the crackles. 4. Floating the surface of modified colloid by steel ball rod in order to erase unnecessary colloid. 5. Tear the masking tape, and the colloid cannot be touched in the three hours of initial solidification. 6. The colloid will be solid next day. In addition, you should pay more attention to the process of usage. The corner of crack is fragile because of the shortage of vibration, so it should be made into oblique angle or back off. The joint bottom cannot limit the transformation of sealant, or it will cause damage after the use of juncture. Juncture sealing depth should be adjusted by inserted to appropriate joint backing materials. If you use the sealant in the correct way, your products absolutely reach the ideal condition.
