How to produce precast terrazzo stair treads

The production process of precast terrazzo stair treads can be described as follows:

Firstly, about the raw material preparation.

The main raw materials for producing precast terrazzo stair treads are cement, stones, pigments, and other materials.

Cement is used to increase the strength and hardness of the stair boards, while stones provide a rough texture to the stair boards for better anti-skid performance.

Pigments are used to adjust the color and pattern of the stair boards to meet different design requirements.

Secondly, Mixing .

During the mixing stage, the mixed raw materials are put into a mixer, along with an appropriate amount of water, and mixed thoroughly to ensure a homogeneous mixture.

Next is the pressing stage.

The mixed material is poured into a pressing machine and pressed under high pressure to form stair boards with certain strength and density. The pressure and time during pressing need to be strictly controlled to ensure that the hardness and density of the stair boards meet the required standards.

After that is the curing stage.

The pressed stair boards need to be placed in a cool and ventilated place for natural drying and hardening. This stage is crucial for ensuring the strength and quality of the stair boards.

Next is the polishing stage.

After curing, the stair boards are polished using a grinding machine to make the surface smooth and even, achieving the desired gloss. During polishing, care needs to be taken to control the speed and force of the grinding machine to avoid damaging the stair boards.

Finally, there is the sealing stage.

After polishing, the stair boards need to be sealed using a special sealing agent to prevent pollution and moisture from penetrating into the stairs. This step ensures the waterproof performance and service life of the stair boards.

It should be noted that during the production of precast terrazzo stair treads, it is necessary to strictly control the quality and proportion of raw materials, as well as the time and temperature of pressing and curing to ensure stable quality and excellent performance of the produced stair boards. At the same time, it is necessary to adjust the production process and parameters according to the actual situation to meet different customer needs and requirements.
