Embodiment 1
[0026] A method for producing through-hole ceramsite, which comprises the following steps:
[0027] 1) Add an appropriate amount of water to the industrial clay to make it into a muddy shape (like plasticine, it has a certain strength and can be molded into any shape), and then add lawn grass, kneading, squeezing, rubbing, so that the soil is fully bonded On the lawn grass, a mixed clay material is formed;
[0028] 2) Knead the mixed clay material to make a cylindrical blank, and then cut it into a cylindrical clay section with a diameter of 30mm and a height of 40mm after pre-drying, and then form a through-ceramsite blank;
[0029] 3) Let the ceramsite blank stand for 24 hours to fully disperse the clay particles, then bake it at 120-150°C for 1-2 hours, then put it into the sintering furnace, slowly raise the temperature to 1200-1300°C, heat-preserve and sinter for 15 minutes and then cool it down, that is into through-hole ceramsite.
[0030] The obtained through-hole ce...
Embodiment 2
[0033] A method for producing through-hole ceramsite, which comprises the following steps:
[0034] 1) Take 120kg of industrial clay, grind it to be less than 100 mesh, 80kg of steel slag, 40kg of water glass (due to the large amount of steel slag, the clay has insufficient adhesion), add appropriate amount of water, make it into mud, add appropriate amount of straw, and stir , so that the powder is fully bonded to the straw to form a mixed clay material;
[0035] 2) The mixed clay material is made into a cylindrical blank, and then cut into a cylindrical clay section with a diameter of 25mm and a height of 30mm, and the through-ceramsite blank is formed;
[0036]3) Place the ceramsite blank for 24 hours to fully hydrate the CaO in the steel slag and disperse the clay particles, then bake it at 120-150°C for 1-2 hours, put it into the sintering furnace, and slowly raise the temperature to 1050-1100°C, After heat preservation and sintering for 20 minutes, it is cooled to form ...
Embodiment 3
[0040] A method for producing through-hole ceramsite, which comprises the following steps:
[0041] 1) Add appropriate amount of water to 80kg of planting soil and fly ash mixture, add 4kg of dextrin to make mud, then add appropriate amount of straw, knead, squeeze and rub to make the soil fully adhere to the straw to form a mixed pottery Mud;
[0042] 2) Knead the mixed clay material to form a cylindrical blank, and then cut the blank into a cylindrical clay section with a diameter of 35 mm and a height of 20 mm to form a through-ceramsite blank;
[0043] 3) After the ceramsite blank is left to stand for 24 hours, it is baked at 110-130°C for 1-2 hours, then placed in a sintering furnace, slowly raised to 1100-1150°C, kept for 20 minutes and then cooled to form a through hole Ceramsite.
[0044] The obtained soil through-hole ceramsite consists of a ceramsite shell and pores inside the ceramsite. The pores are open pores or through pores, and the through pores are connected...
