At present, a zinc pot roller of a hot galvanizing unit at home and abroad is a ceramic element with high performance for pursuing high speed and long service life, and the ceramic element after use is found to have a large number of corrosion holes in a non-friction area along with the lengthening of a single use period and the increase of the use times, and the abrasion loss of the friction area is increased along with the increase of the use times. The investigation and analysis show that the ceramic element adopted at present is still compact although the manufacturing process is improved, so that microscopic small holes still exist, and the microscopic small holes are continuously washed and grown by molten zinc liquid to become small holes in the subsequent high-speed and long-time use process, and even the abrasion loss of friction areas and non-friction areas is increased.
Considering that if the ceramic element production process is optimized, the ceramic porosity is reduced by increasing the density of the ceramic element, the production cost of the ceramic is greatly increased. It is therefore desirable to have a sealer that can seal small pores within a ceramic, thereby reducing the number of small pores and the size of small pores, thereby effectively reducing the amount of wear on the ceramic, extending the service life, and reducing the coefficient of friction, to facilitate high-speed production.
