Embodiment 1
[0027] A kind of mud, its preparation raw material is component A and component B, and component A is the following components by mass parts:
[0028] 40 parts of feldspar, 8 parts of white mud, 4 parts of coffee mud, 8 parts of black mud, 14 parts of Yongchun soil, 6 parts of china clay, 20 parts of kaolin and 28 parts of water; component B is water glass, and the amount of water glass is 0.3%-0.5% of the total mass of sub-A.
[0029] Among them, the porcelain clay is Chaozhou porcelain clay; the white clay is Zengcheng white clay; the kaolin is Maoming kaolin.
[0030] The preparation method of above-mentioned mud is:
[0031] 1) Ball milling slurry: adding feldspar, white mud, coffee mud, black mud and water into a ball mill for ball milling to obtain slurry A;
[0032] 2) Add Yongchun clay, china clay, kaolin and water glass to slurry A, and mix evenly to obtain slurry B. Specifically, it can be: add Yongchun clay, china clay, kaolin and water glass to the slurry A, mix...
Embodiment 2
[0051] The difference between this embodiment and Example 1 is: the white clay is Guangxi white clay, the kaolin is Guangxi kaolin, all the other formulas are the same as in Example 1, and the preparation method is also the same as in Example 1.
[0052] The application method of this embodiment mud is:
[0053] Put the mud into the grouting stale storage pool for aging, and after the aging is completed, send the mud to the grouting production line to produce the green body.
[0054] 1), micro-pressure grouting
[0055] Put the mud into the grouting stale storage tank (micro-pressure grouting stale storage tank) for aging. After the aging is completed, send the mud to the micro-pressure grouting production line to produce the green body. During the aging process of the micro-pressure grouting grouting storage pool, the thixotropic index of the mud is controlled to be 70-90, and the temperature is 28-35°C; in the micro-pressure grouting production line, the suction time is 100...
Embodiment 3
[0065] A kind of mud, its preparation raw material comprises component A and component B, and component A comprises the following components by mass parts:
[0066] 35 parts of feldspar, 12 parts of white mud, 6 parts of coffee mud, 12 parts of black mud, 10 parts of Yongchun soil, 10 parts of china clay, 15 parts of kaolin and 28 parts of water; component B is water glass, and the amount of water glass is 0.3%-0.5% of the total mass of sub-A.
[0067] Among them, the porcelain clay is Chaozhou porcelain clay; the white clay is Guangxi white clay, and the kaolin is Guangxi kaolin.
[0068] The preparation method is the same as in Example 1.
[0069] The application method and effect of this embodiment mud are the same as in Embodiment 2.
