Problems solved by technology

During transportation, hoisting, impact, and sudden temperature changes, it is easy to explode porcelain, and it is difficult to repair. Moreover, under the conditions of high temperature, high pressure and strong acid, the material of the reactor is easy to corrode and wear, and its service life is greatly shortened.
