How to distinguish between genuine and fake leather?

To understand how leather has to know how to distinguish between true and false, “leather” is the most common word in the leather goods industry. It is also a customary name for people to distinguish between synthetic leather and leather. The variety of leather is different and the quality varies. There is also a great disparity.

Here are some common ways to identify the dermis

First, feel

If the surface of the leather is touched by hand, it feels smooth (the grain is processed into thick skin), and the soft, full and elastic feeling is the leather.

Second, the eye

It is mainly used to identify the type of leather and the quality of leather grain, observe the surface of the dermis has more obvious pores and patterns, and synthetic leather, although it also imitates pores, but it is not really clear. In addition, the opposite side of the synthetic leather has a layer of textiles as the bottom plate. This textile bottom plate is used to increase its tensile strength, and the reverse side of the leather is not such a layer of textiles. This identification is the simplest and most practical method.

Third, smell

Good quality skin does not have any unusual odor. All dermis have the smell of leather. If there is a pungent odor, it may be handled badly during the tanning process and a certain chemical raw material is used excessively.

Fourth, light

The odor of the genuine leather is almost the same as the odor after the hair is ignited, and it does not scab after burning. It can be grinded with a finger; the artificial leather emits a pungent odor and burns.

Coal Activated Carbon For Recycling Of Solvents

Using high quality coal as raw material for solvent recovery, coal is mainly used in the recovery of benzene, toluene, ether, alcohols, gasoline, three, methyl chloride, organic solvents and other hydrocarbons, as well as the vapor recovery of hydrocarbon compounds.

Use: Used in the seperation and recycling of aethers, ketons, alcohols, tetrahydrofuran, methylene dichloride, trichloromethane, trichloroethylene, chlorinated polyvinyl chloride, carbon bisulfide, benzene, gasoline etc.
