Abstract
The invention discloses a method for maintaining a clay brick surface layer, which comprises the following steps: s1, moving the clay bricks into a curing chamber, placing the formed clay bricks into a goods shelf, conveying the clay bricks into the curing chamber, adjusting the humidity of the curing chamber, wherein the humidity is not lower than 65% rh, S2, increasing the temperature in the curing chamber to 50 ℃, standing for not less than 36 hours, S3, covering a film, curing, closing the fan heater, covering a plastic film on the clay bricks, curing for more than 7 days, S4, spraying a hydrophobic agent, moving a plurality of nozzles to the goods shelf by adopting a movable vertical support, and spraying a mist hydrophobic agent through a Venturi effect; and in the spraying process, overturning the clay bricks to uniformly spray all the surfaces, detecting S5, after the water repellent is condensed, dripping water on the surfaces of the samples to form a ball shape, observing whether water drops penetrate into the test pieces or not, and air-drying and packaging S6. The invention improves the strength of the clay brick, avoids the precipitation of the inorganic salt of the curing agent in the clay brick, ensures the appearance of the clay brick and improves the durability.
Description
Technical Field
The invention belongs to the field of clay brick production, and particularly relates to a clay brick surface layer maintenance method.
Background
In the development process of the domestic economic system, the construction waste gradually becomes a very spotlighted topic. The total amount of recycling, reprocessing and the like of the construction waste is only about 5000 ten thousand tons, and the utilization rate of construction waste resources is about 5 percent. Therefore, the construction waste recycling project becomes the future economic and social development trend, and the current construction waste comprises waste soil, residual mud, silt and the like, and the manufacturing process taking the soil regeneration brick as the visual angle has important research value due to the configuration of the process, the raw materials and the like.
After the existing clay brick is produced, because the strength of a pure clay brick is obviously different in the using amount of a curing agent, when the water content of raw material clay is higher, the addition of a curing agent aqueous solution is insufficient in the stirring process, and the finished clay brick has low strength and is easy to break and crush. When the water content of the raw material soil is low, the curing agent aqueous solution is sufficiently added in the stirring process, the strength of the finished product soil brick can be ensured, but the brick body is subjected to efflorescence phenomenon during the curing period, which is caused by the inorganic salt precipitation of the curing agent.
The efflorescence problem not only can influence the appearance image of the clay brick, but also can influence the on-time delivery acceptance of projects, can also influence the strength and durability of the clay brick in serious cases, has to be reworked, seriously influences the enterprise image and causes economic loss.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a method for maintaining a surface layer of a clay brick, which can reduce the occurrence of the efflorescence phenomenon of the clay brick.
In order to achieve the purpose, the invention adopts the following technical scheme: a method for maintaining a clay brick surface layer comprises the following steps:
s1, moving the product into a curing room,
putting the formed clay brick into a shelf, transporting to a curing room, adjusting the humidity of the curing room to be not less than 65% rh,
s2, the room temperature is increased,
the temperature in the curing room is increased to 50 ℃ by adopting a warm air blower, the standing time is not less than 36 hours,
s3, film covering and maintaining
Closing the warm air blower, covering the plastic film on the clay brick, maintaining for more than 7 days,
s4, spraying a water repellent,
a movable vertical bracket is adopted, a plurality of nozzles are moved to a goods shelf, and the mist water repellent is sprayed through the Venturi effect; in the spraying process, the clay bricks are turned over to ensure that all surfaces are uniformly sprayed,
s5, detecting the position of the target,
after the water repellent is condensed, selecting a clay brick according to the set proportion of the sample block, dripping water on the surface of the sample to be spherical, observing whether water drops penetrate into the test piece or not,
s6, air drying and packaging
Detecting unqualified, and spraying the water repellent again; and (5) detecting to be qualified, and packaging the clay brick.
Further, the water repellent in the step S2 is Dow Corning SHP50 organic silicon.
Further, the clay bricks do not exceed 8 layers when packaged.
Further, in step S2, a plastic film is sleeved on the outside of the shelf, and the shelf is closed.
Further, in the step S5, the extraction ratio is 1% to 2%.
The invention has the beneficial effects that:
the method for curing the surface layer of the clay brick has the advantages that the proper temperature and humidity and curing method are selected, the strength of the clay brick is improved, meanwhile, the water repellent is sprayed, the inorganic salt precipitation of a curing agent in the clay brick is effectively avoided, the appearance of the clay brick is ensured, and the durability is improved.
