       Dryer is one of the necessary equipment for papermaking enterprises, and the main loss is wear and corrosion. Wear includes blade wear, felt wear, slurry wear and corrosion. Jinan Tianmeng New Material Technology Co., Ltd. has successfully developed "a drying cylinder with tungsten carbide wear-resistant ceramic + nano-composite non-stick coating" in the continuous thermal spraying technology construction experience and innovation, which effectively solves the wear and tear of the drying cylinder. Corrosion problem.

Tungsten carbide: is a compound composed of tungsten and carbon. The molecular formula is WC and the molecular weight is 195.85. It is a black hexagonal crystal, with gray powder with metallic luster, the hardness is similar to that of diamond, and it is a good conductor of electricity and heat. Tungsten carbide is chemically stable. Teflon: Also known as polytetrafluoroethylene (abbreviated as PTFE), generally referred to as "non-stick coating" or "easy-to-clean material". This material has the characteristics of acid and alkali resistance, resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of high temperature resistance, and its friction coefficient is relatively low, so it can be used for lubrication, and it has also become an ideal coating for easy cleaning.


"A dryer with tungsten carbide wear-resistant ceramic + nanocomposite non-stick coating" developed by wococarbide.com, its main features are as follows:

1. A combination of equipment components and two new materials.

2. The quality and efficiency of paper will be doubled. Improve the bonding ability of the coating to the surface of the workpiece by applying a bonding agent. After sintering, it forms a network structure with the bonding agent. The drying cylinder surface is coated with Teflon coating instead of the original dryer blade device. Under the condition of ensuring the normal drying and peeling performance of the paper sheet, the operation and maintenance costs of the equipment are reduced, and the cost of spare parts is reduced. It can reduce product cost and improve production efficiency in many aspects. Effectively solve the problems of cleaning and maintenance of machinery and equipment caused by material adhesion or corrosion in the production process
