Problems solved by technology

The traditional curing method is natural curing. Natural curing is to put the formed cement products in the natural environment, use the ambient temperature, and sprinkle water to keep them moist. The disadvantage of this method is that it requires a lot of manpower and can only be produced at room temperature. Continuous production, poor control of temperature and humidity, high production costs, and unguaranteed product quality

Abstract

The invention discloses a preparation method of a cement product. The preparation method comprises the following steps: (1) preparing raw materials for a cement product, mixing the raw materials with water, stirring the mixture, then adding the mixture into a die, and carrying out wet plate moulding; (2) placing the wet plate into a curing kiln to carry out first curing, and controlling the curing temperature in a range of 25 to 30 DEG C and the humidity more than 85%; (3) performing demoulding, after demoulding, placing the sheet into a curing kiln to carry out secondary curing, and controlling the curing temperature in a range of 25 to 30 DEG C and the humidity in a range of 70 to 85%; and (4) covering a film on the sheet in the outdoor and carrying out curing to obtain the finished product. The provided preparation method has the advantages that the quality of the prepared cement product is controllable, labor and time are saved, and the operation method is safe and reliable. The prepared cement product can be used as an exterior wall cladding of a building, has the advantages of low carbon, environment-friendliness, energy saving, deformation resistance, and recyclable property, and has the characteristics of quick moulding, short production period, good stability, fireproof property, corrosion resistant performance, and durability.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a method for preparing cement products. Background technique [0002] The curing process of cement products is an extremely important process link in the production process of cement products. It determines the quality of the product, and at the same time, it also has an important impact on the production cycle, production efficiency and energy consumption indicators. The traditional curing method is natural curing. Natural curing is to put the formed cement products in the natural environment, use the ambient temperature, and sprinkle water to keep them moist. The disadvantage of this method is that it requires a lot of manpower and can only be produced at room temperature. Continuous production, poor control of temperature and humidity, high production costs, and unguaranteed product quality. [0003] The information disclosed in this Background section is only for enhancing ...
