The difference between rubber anti-static mat and PVC anti-static mat
The rubber material used in the rubber anti-static mat is called nitrile rubber. The characteristics of this material belong to natural semiconductors, 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.
PVC anti-static mats are relatively inexpensive to produce. 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. , causing the anti-static effect to decline. In recent years, due to the rising price of rubber, some
The rubber mat of the manufacturer is more or less mixed with some PVC materials, but it can not exceed 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. The two can be distinguished by the following points: First, smell the odor, cut the two mats into thin strips, ignite with fire, if the smoke is very dark, and the plastic smell with the thorn is PVC mat. Second, look at the flames. After the ignition, the rubber mats have been very strong. When the PVC burns, it will produce a creaking sound.
Because the composition of PVC contains a polyvinyl chloride, this element is anaerobic. Third, look at the gray gravel. After burning, the rubber ash has no hard block, and vice versa. Fourth, the surface is scratched, and the object is scratched on the surface of the table mat several times, the PVC material will not leave scratches, and the surface of the rubber table mat has scratches. Fifth, resilience, cut two pieces of table mats of different materials, firmly grip, the fastest return flat, no deformation, and the soft touch is a high quality table mat. Sixth, the softness, the rubber mat is relatively soft, and the PVC mat is relatively hard. If you add some softener in the production process of PVC, the same feel is very soft, even softer than rubber, but if you cut it, you will see PVC foam pad with many foamed holes, and rubber mat Then no.
