Anti-static mat material analysis
ESD rubber material used in the anti-static rubber table mat is called nitrile rubber. The characteristics of this material belong to the natural semiconductor, and it has anti-static function. Its molecular structure is composed of numerous carbon chains. The carbon chain stores a certain amount of static electricity, so the static electricity generated on the surface of the table mat can be introduced into the inner layer in a short time, and the residual static electricity passes through the conductive layer smoothly. Introduce the ground with the ground. The rubber mat is characterized by the ability to store a large amount of static electricity and discharge and electricity in an instant, and the service life is generally more than 5 years.
Anti-static mat
The cost of PVC mat is relatively low. The reason why it can prevent static electricity is because it is mixed with antistatic agent in the production process. This product is a chemical. After 3 to 6 months of use, it will slowly evaporate, resulting in Anti-static effect is declining.
In recent years, due to the rising price of rubber, some manufacturers have more or less PVC mats, but not more than 30%, otherwise it will affect the quality and service life. Some manufacturers will use recycled rubber as a substitute, but the carbon chain in the recycled rubber has been destroyed, and there is no effect of storing static electricity.
5 Identification skills of rubber table mats and PVC table mats
5.1 Resilience
Cut two mats of different materials, hold them tightly, and quickly return to the flat, no deformation, and the soft feel is a high-quality table mat.
5.2 smell
Cut the two mats into thin strips and ignite them with fire. If the smoke is very dark, and the pungent plastic smell is PVC mat.
5.3 Look at the flame
After the ignition, the rubber table mat flame has been very prosperous, and the PVC will produce a creaking sound when it burns. At that time, because the PVC component contains a kind of polyvinyl chloride, the element is anaerobic.
5.4 Look at the ash
After burning, the ash of the rubber has no hard block, whereas the ash of PVC has a hard block.
5.5 Surface scratches
Use the object to make a few times on the surface of the table mat, the PVC material will not leave scratches, and the surface of the rubber table mat will be scratched.
5.6 Softness
The rubber mat is softer and the PVC mat is harder. If you add some softener in the PVC production process, the same feel is very soft, even softer than rubber, but if you cut it, you will see that the PVC table mat has many foaming holes, the rubber mat does not .
