Cement production line equipment management can be refined into operational links such as inspection management, lubrication management, maintenance management, spare parts management, and site management. Intelligent point inspection operations have the ability to quickly and accurately determine faults. Through vibration measurement, temperature measurement, image acquisition etc. , a large number of point inspection data are obtained, and the data is analyzed on the server, and the potential abnormal situation in the operation of the equipment can be alerted, which greatly reduces the incidence of equipment failure.Equipment lubrication should be managed in a professional and centralized way. The production department should be responsible for the leadership. Each workshop should establish the corresponding equipment lubrication account, and regularly sample and test the oil station of large-scale host equipment, and do a good job in oil quality monitoring. Equipment repair and maintenance should be carried out in strict accordance with the overhaul operating procedures. For large mainframe equipment, professional maintenance teams should be properly introduced. Spare parts management should ensure reasonable inventory and control the proportion of spare parts reserve funds. On-site management should vigorously promote 6S management to create a clean and tidy workplace.

SiO₂ aerogel/foam cement composites were prepared by the vacuum impregnation method. Subsequently, the composition of pore structures, microstructure, hydrophobicity, density, mechanical properties and thermal conductivity of the composites have been systematically studied by SEM, FTIR and contact angle measuring instrument. The results show that SiO₂ aerogels were gelled and dried in the surface pores of the foam cement, finally fill with foam cement pores in the form of particles; according to the FTIR curve, there is no significant change in the groups of aerogels after the aerogels were gelled and dried on the alkaline surface of foam cement; the hydrophobic angle on the surface of modified foam cement is 141°; the density of the foam cement after impregnation is 309.4kg/m³, the compressive strength is 0.56MPa, and the coefficient of thermal conductivity is 0.046W/(m·K).
