Light-weight partition wall board blended with pharmaceutical waste salt residues and preparation method of light-weight partition wall board

Abstract

The invention discloses a light-weight partition wall board blended with pharmaceutical waste salt residues and a preparation method of the light-weight partition wall board. The light-weight partition wall board is prepared from cement, the pharmaceutical waste salt residues, coal ash, sand, a water reducing agent, an air entraining agent, a foaming agent, calcareous materials, light-weight particles and water. The preparation method comprises the following steps: mixing and stirring the pharmaceutical waste salt residues and the calcareous materials according to a stoichiometric ratio in a reaction kettle and carrying out water mist spraying; drying a mixed material of the pharmaceutical waste salt residues and the calcareous materials; mixing the foaming agent and the water according to the stoichiometric ratio and preparing physical foams by utilizing a foam generator; mixing the mixed material of the pharmaceutical waste salt residues and the calcareous materials, the cement, the coal ash, the sand, the water reducing agent, the air entraining agent and the light-weight particles according to the stoichiometric ratio and stirring by adding the water and the physical foams so as to obtain a homogeneous material slurry; and injecting the homogeneous material slurry into a molding die and demolding, thereby obtaining the light-weight partition wall board. According to the method, the pharmaceutical waste salt residues are fully utilized, so that the pharmaceutical waste salt residues have a coagulating function and an early age strengthening function during a production process, thereby not only improving the early age strength of the board material and shortening the cycle period of the molding die but also realizing environmental friendliness and waste utilization so as to decrease the cost.

Description

technical field [0001] The invention relates to the field of novel wall materials, in particular to a lightweight partition wall board mixed with pharmaceutical waste salt slag and a preparation method thereof. Background technique [0002] With the advancement and deepening of wall material innovation, building energy conservation and housing industrialization, lightweight partition panels are characterized by their light weight and high strength, thermal insulation, fire and flame retardant, waterproof and moisture-proof, and time-saving, manpower-saving, and increased energy consumption. The incomparable advantages of other types of wall materials, such as large indoor use area, have been widely used in building enclosures. Cement-based lightweight partition boards are usually cured under natural conditions after forming. The advantage of this curing condition is to save energy and reduce costs, but the disadvantage is that when the ambient temperature is low, such as in ...

Problems solved by technology

Cement-based lightweight partition boards are usually cured under natural conditions after forming. The advantage of this curing condition is to save energy and reduce costs, but the disadvantage is that when the ambient temperature is low, such as in winter production, the board needs a long time. The maintenance cycle can only be demoulded, which seriously affects the turnover of the mold and the continuity of production, and even affects the quality of the product due to freezing
