Sealant is a primer with the shape of the sealing surface deformation, not flowing, there is a certain adhesion of the sealing material. Configuration is used to fill the gap , in order to play the role of the adhesive seal . Typically bituminous , natural resins or synthetic resins such as natural rubber or synthetic rubber or dry dry viscous material as the base material , with talc , clay , carbon black, titanium dioxide and inert fillers such as asbestos , then add plasticizers, solvents , curing agent and catalyst is made. Sealant has good sealing performance , and good heat resistance, pressure resistance, dense medium characteristics, use of simple , commonly used in mechanical and electrical products still seal between joints , as well as more complex threaded joints sealing , etc. , sealants, liquid sealant is generally divided into two categories with anaerobic ,security seals and more commonly used liquid sealant role has the following five effects:
1 , the surface effect
No matter how solid gasket compression , it will not completely fill the joints on uneven, there will always be a gap at the interface , and the liquid sealant was able to fill all depressions , showing a good sealing effect.
2 , adhesion results
Liquid sealant in liquid form , has a certain viscosity , having a joining surface of the metal adhesion , sealing beneficial .
3 , the thin film effect
In the joints between the liquid sealant is screw fastening , the formation of a film with the same space at the same time is very consistent with the surface . Meanwhile , the thinner the film , the greater resilience , the better seal.
4 , flow and pressure resistance
Using liquid metal sealant joints , gaps are generally less than 0.1mm , and the liquid sealant is a liquid of high viscosity , it is difficult to flow , thereby maintaining its good sealing .
5, the volume change and mobility
Solid gasket leak-proof effect is the compression of the cushion sheet elastic deformation . The liquid sealant is leakproof volume in the compression and stretching deformation , it does not exist solid gasket compression deformation, so there is no compression fatigue , pull tight seals elastic failure , stress relaxation and other phenomena , and it is always connected adhesion of the interface , the interface can be prevented leakage .
security seal labels cylinder made of metal, plastic Outsourcing ABS plastic, for clip spring lock body structure, lock body surface using blanching, laser type and serial number, bar code, color can be customized according to user requirements, wire diameter φ1. 8, the length can be produced according to user requirements, pulling up to F ≥ 250KG. Scope: For Customs containers, tankers, container trucks and other purposes.
