Embodiment 1
[0015] Step 1: Slurry Preparation
[0016] Firstly, sort the waste high-silica glass fibers from the waste products, remove the plastic and metal objects, and cut them into waste high-silica glass fiber short filaments with a length less than 2 mm;
[0017] Then, put 95% of waste high-silica glass fiber short filaments with a length less than 2 mm by mass fraction, 1% calcium carbonate, 3% kaolin and 1% lactic acid into the ball mill jar, then according to 45ml distilled water / 100 grams of batch material, Then add distilled water to the ball mill jar;
[0018] Finally, put in zirconia balls of the same weight as the batch and mill for 36 hours, pour the slurry out of the ball mill tank, and pass through a 100-mesh standard sieve to obtain the molding slurry;
[0019] The second step: grouting and trimming
[0020] Slowly pour the prepared slurry into the gypsum mold, and constantly vibrate the gypsum mold. When the thickness of the slurry absorbed by the inner wall of the gy...

[0024] Step 1: Slurry Preparation
[0025] Firstly, sort the waste high-silica glass fibers from the waste products, remove the plastic and metal objects, and cut them into waste high-silica glass fiber short filaments with a length less than 2 mm;
[0026] Then, put 96.5% of waste high-silica glass fiber short filaments whose length is less than 2 mm by mass fraction, 0.3% calcium carbonate, 2.7% kaolin and 0.5% lactic acid into the ball mill jar, then according to 45ml distilled water / 100 grams of batch material, Then add distilled water to the ball mill jar;
[0027] Finally, put in zirconia balls of the same weight as the batch and mill for 36 hours, pour the slurry out of the ball mill tank, and pass through a 100-mesh standard sieve to obtain the molding slurry;
[0028] The second step: grouting and trimming

[0033] Step 1: Slurry Preparation
[0034] Firstly, sort the waste high-silica glass fibers from the waste products, remove the plastic and metal objects, and cut them into waste high-silica glass fiber short filaments with a length less than 2 mm;
[0035] Then, put 96% of waste high-silica glass fiber short filaments whose length is less than 2 mm by mass fraction, 0.1% calcium carbonate, 3.5% kaolin and 0.4% lactic acid into the ball mill jar, then according to 45ml distilled water / 100 grams of batch material, Then add distilled water to the ball mill jar;
[0036] Finally, put in zirconia balls of the same weight as the batch and mill for 36 hours, pour the slurry out of the ball mill tank, and pass through a 100-mesh standard sieve to obtain the molding slurry;
[0037] The second step: grouting and trimming
[0038] Slowly pour the prepared slurry into the gypsum mold, and constantly vibrate the gypsum mold. When the thickness of the slurry absorbed by the inner wall o...
