Description

Integrated pulping equipment

technical field

Background technique

Gypsum self-leveling is a new type of floor material developed in the past two years. It is a dry-mixed powdery material composed of a variety of active ingredients. It can be used on site by mixing with water. It has a wide range of uses and can be used in industrial plants, workshops, storage, Commercial stores, exhibition halls, gymnasiums, hospitals, various open spaces, offices, etc., are also used in homes, villas, and small warm spaces. They can be used as veneer layers or as wear-resistant base layers. During self-leveling construction, self-leveling mortar only needs to be laid on the construction ground, and the effect of leveling can be achieved with a little leveling or no leveling. Because of its advantages of convenient construction, fast construction speed and cost saving, its application is more and more widely.

Since the self-leveling mortar needs to be paved in a short time after preparation, it is difficult to transport it through the mixing station over a long distance. Generally, a mixing device is installed at the construction site and prepared as needed.
