How to determine if the stability of calcium silicate board
To determine if the stability of calcium silicate board equipment has deteriorated,the key is to look at four major signals:"product consistency,operational continuity,energy consumption efficiency,and component status".If two or more of these signals are present,it can be determined.The specific details are as follows:
The consistency of product quality has declined
The thickness deviation of the sheet exceeds±0.3mm,and the flatness error is±0.3mm.2mm/m³,with uneven density within the same batch;The proportion of corner cracking and surface sanding has increased,the strength of the plates fluctuates greatly,and the pass rate of random inspection has dropped by more than 10%.
2.The continuity of equipment operation deteriorates
The number of shutdowns due to faults has increased by more than 50%compared to the initial stage,and PLC alarms,hydraulic leakage,and abnormal motor noises occur frequently.The equipment is difficult to start up,operates stably,the formed mesh belt deviates,and the autoclave is not sealed tightly,requiring frequent manual adjustments.
3.Abnormal energy consumption and efficiency
The electricity/steam consumption per unit capacity increases by 10%to 20%(excluding changes in raw materials and processes).The efficiency of stirring dispersion and forming dehydration has declined,and the production cycle of plates of the same specification has been extended by more than 15%.
4.Abnormal status of key components
The forming pressure rollers and stirring blades are severely worn,the mesh belt is stretched and deformed,and the pressure-bearing components show corrosion and leakage.Sensor data drift(requiring frequent calibration),aging of electrical components,and delay in automation response.
After eliminating external factors such as raw materials,processes,and operations,if the above signals are obvious,timely maintenance(replacing vulnerable parts,calibrating the system,and anti-corrosion treatment)is required.
