The carbon can be removed or partially removed by heating the catalyst to 500°C in fresh air and holding it for 2-4 hours.
The organic synthetic material anti-skid agent is slightly more expensive, but it has suitable hardness and elasticity, has no sharp edges and corners, can withstand frictional impact, and is not easy to break. The organic synthetic anti-skid agent has good adhesion to the coating base material, is not easy to fall off, and the relative density is close to that of the commonly used coatings, so it is not easy to settle in the coating, and it can still remain suspended in the coating for easy construction. Choose suitable particle size, spray coating can be used, and it is easy to get a non-slip coating film with evenly distributed anti-slip agent particles.
Polyvinyl chloride resin particles (80~120um in size) and sand particles were used as anti-skid agents, and spray coating was used for construction. The anti-skid and wear resistance properties of the same coating were compared.
Comparison of anti-slip and abrasion resistance of two types of anti-slip agents. Polyvinyl chloride resin particles H particles
The coating film with sand as the anti-slip agent has great anti-slip performance and obvious anti-slip effect in the initial stage of use, but as the number of frictions increases, its anti-slip performance is greatly reduced. On the contrary, the coating film using polyvinyl chloride resin particles as the anti-slip agent, although the anti-slip performance is worse than the use of sand particles at the initial stage of use, but with the increase of the number of frictions, its anti-slip performance hardly decreases, indicating that its anti-slip effect can be long-term Keep, have persistence. It is also known from Table 13-12 that the coating film with polyvinyl chloride resin particles as the anti-skid agent has better abrasion resistance than the coating film with sand particles as the anti-skid agent.
With the continuous development of polymer chemicals and synthetic organic chemicals, the use of anti-skid agents for organic synthetic materials will become more and more widespread, and new varieties of anti-skid agents for organic synthetic materials will continue to appear. But it is what people want to avoid as much as possible.
