Problems solved by technology

[0002] The traditional molding method of asbestos tiles adopts the vibrating scraper method, but the strength of the asbestos tiles made by this method is not high, and the asbestos tiles are prone to cracks
Therefore, the vibratory stamping method to make asbestos tiles came into being. It can improve the strength and compactness of the mortar. Large dimples and more air bubbles and blisters
In this way, on the one hand, the workload of plastering is increased, and on the other hand, since fine sand slurry is added to the general plastering, it is easy to cause shrinkage cracks in the finished asbestos tiles.
2. There is a large adsorption force between the die and the asbestos tile, it is difficult to lift the die, and sometimes even destroys the mortar structure that has been vibrated

Embodiment Construction

[0032] The present embodiment will be described in detail below in conjunction with the accompanying drawings.

[0033] The invention adopts a hollow die structure capable of natural exhaust, which can discharge part of the water and air in the mortar during the vibration compaction process. Die structure includes attached vibrator 1, exhaust pipe 2, additional load block 3, upper cover plate 4, exhaust chamber 5, lower cover plate 6, rib plate 7, guide cone 8, vibration transmission frame 9, lifting hole 10. Attached vibrator 1 is provided with a vibration transmission frame 9, the vibration transmission frame 9 is welded by a steel plate and a channel steel, an additional load block 3 is arranged at the bottom of the vibration transmission frame 9, and the upper cover plate 4 is located below the vibration transmission frame 9, and the upper cover plate 4, the lower cover plate 6 and the rib plate 7 form an exhaust chamber 5, and the rib plate 7 adopts a steel plate with a ...

Abstract

The invention discloses an asbestos tile forming method, which is characterized in that a hollow die structure capable of naturally discharging air is adopted, and partial water and air in mortar can be discharged in the vibrating compaction process; the asbestos tile forming method comprises the following steps: (1) spreading the mortar and pre-vibrating; (2) spreading filter cloth; (3) discharging air, performing vibrating compaction molding, stably putting down the die, enabling a guide cone to fall into a guide hole, and starting a vibrator for discharging air and performing vibrating compaction, wherein during vibration, a frame is tightened by a wedge at any time, and the wedge is not loosened or does not fall off; and (4) trimming a tile shape. By the method, the compactness of an asbestos tile is improved, the breaking strength of the asbestos tile is improved and a shrinkage value is reduced.

Description

technical field [0001] The invention relates to an asbestos tile, in particular to a molding method of the asbestos tile. Background technique [0002] The traditional asbestos tile molding method adopts the vibrating scraper method, but the strength of the asbestos tiles made by this method is not high, and the asbestos tiles are prone to cracks. Therefore, the vibratory stamping method to make asbestos tiles came into being. It can improve the strength and compactness of the mortar. Large areas of dimples and more air bubbles and blisters. In this way, on the one hand, the workload of plastering is increased, and on the other hand, since fine sand slurry is added to the general plastering, it is easy to cause shrinkage cracks in the finished asbestos tiles. 2. There is a large adsorption force between the die and the asbestos tile, it is difficult to lift the die, and sometimes even destroys the mortar structure that has been vibrated. The reason for these situations is...
