[0024] (1) Preparation of lightweight partition board mixture

[0025] Weigh 65 parts of Portland cement, 3 parts of polypropylene fiber, 2 parts of cellulose, 1.5 parts of polyvinyl alcohol, 4 parts of waterproofing agent, 8 parts of foaming agent and 3 parts of non-burning ceramic powder by weight; Put the raw materials other than the foaming agent into the cement mixing tank, add an appropriate amount of water, and stir evenly to obtain a mixed slurry; add an appropriate amount of water to the foaming agent, mix evenly, and then put it into a foaming machine for foaming to obtain a stable structure. After foaming, the obtained foam and the prepared mixed slurry are poured into a foam mixing machine, during which the stirring is continued to obtain a lightweight partition wall board mixture.

[0026] The waterproofing agent is made by mixing stearic acid, soda ash, sodium hydroxide and sodium alkylbenzene sulfonate with a mass ratio of 50:6:1.5:1; the foaming agent is made b...

Embodiment 1

[0029] A maintenance method for a lightweight partition board, comprising a steam curing stage and a curing stage after demoulding, the specific steps of the steam curing stage are as follows: send the forming mold filled with the lightweight partition board mixture to In the steaming room, it is divided into heating, constant temperature and cooling stages according to the temperature. The heating stage is also divided into three stages in turn: the first stage is heated to 30°C, the relative humidity is 70%, and the temperature is kept for 25 minutes; the second stage is heated to 45°C. ℃, relative humidity is 80%, keep warm for 15min; in the third stage, the temperature is raised to 50℃, the relative humidity is 80%, and then enters the constant temperature stage; The relative humidity is 60%; the three stages of heating, constant temperature and cooling stage are cured for 20 hours in total, and then the demoulding is carried out, and the curing stage after demoulding is en...

Abstract

The invention discloses a lightweight partition board maintenance method which comprises a steam maintenance phase and maintenance phase after demolding; the steam maintenance phase comprises the following steps of sending a forming mold into which a lightweight partition board mixing material is injected to a steam maintenance room, dividing the phase into a temperature raising phase, a constanttemperature phase and a cooling phase according to the temperatures, performing the three phases of the temperature raising phase, the constant temperature phase and the cooling phase for maintenancefor 20-24h, then performing demolding, and entering the maintenance phase after demolding, wherein the temperature raising phase is also sequentially divided into three phases, in a first phase, a temperature is raised to 30-35 DEG C, a relative humidity is 70-80 percent, and heat preservation is performed for 20-25min; in a second phase, the temperature is raised to 45-55 DEG C, a relative humidity is 80-85 percent, and heat preservation is performed for 10-15min; and in a third phase, the temperature is raised to 50-60 DEG C, a relative humidity is 80-85 percent, and the constant temperaturephase is entered. The maintenance method is simple in process and low in cost, solves the problems of low strength, poor water resistance, buckling deformation, internal cracking and the like of a partition board and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of wall body processing and production, in particular to a maintenance method for lightweight partition boards. 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. [0003] The maintenance stage of the lightweight partition board is an important period for the formation of the strength of the partition board, and the hydration reaction continues to occur inside it. The faster the hydration rate and the more hydration products, the higher the ...
