　　The dimensional errors of the slabs produced by asbestos tile equipment are mainly influenced by four types of factors:equipment accuracy,raw material characteristics,process parameters,and operation management.The specific factors are as follows:

asbestos tile equipment

　　1.Equipment accuracy and wear

　　Dimensional deviations and insufficient flatness of the forming mold will directly result in the length,width and thickness of the asbestos tile not meeting the standards.Uneven clearance between the pressure rollers and deviation of the conveyor belt can cause inconsistent thickness of the slabs.After long-term use,the wear and deformation of the mold and the blunting of the cutting knife will further magnify the dimensional error.Loose gears and chains in the transmission system will affect the stability of the equipment's operating speed and indirectly lead to dimensional deviations in cutting.

　　2.Raw material characteristics and ratios

　　Unstable ratios of asbestos fibers,cement and quartz sand can cause fluctuations in the consistency and moisture content of the slurry,inconsistent curing shrinkage rates of the slab,and dimensional deformation after drying or curing.Uneven particle size of raw materials and fiber agglomeration can lead to uneven distribution of slurry,significant differences in local density of the slab,and subsequently cause warping and dimensional deviations at the edges and corners.

　　3.Process parameter control

　　Insufficient or excessive forming pressure will cause deviations in the thickness of the slab.If the speed of the slurry distribution does not match that of the conveyor belt,it will lead to dimensional errors in the length and width of the sheet.Improper control of temperature and humidity during the curing stage,large fluctuations in environmental humidity during natural curing,or insufficient temperature and time during steam curing can cause uneven shrinkage of the board,affecting dimensional accuracy.

　　4.Manual operation and management

　　In semi-automatic production lines,unstable manual feeding and offset positioning of the slabs will directly affect the forming dimensions.Errors in manually adjusting the position of the cutting knife during the cutting process can also lead to the size of the finished product exceeding the standard.
