Embodiment 1
[0030] Embodiment 1 The production of the used stone of the application method
[0031] Mix various powders according to the ratio of 90% aluminum oxide, 9% silicon dioxide, 0.5% magnesium oxide, 0.3% iron oxide, and 0.2% calcium oxide by weight, pass through a 200-mesh sieve, and place In a spherical mold, it is sintered at 1500±50 degrees Celsius to set the shape. Add 95 porcelain alumina ceramic grinding balls and grind in a ball mill for 12 hours.
[0032] The stones made are smooth white spheres of uniform size, with a bulk density of about 3.6g / cm 3 , the Mohs hardness is about 9Mohs (the Mohs hardness of the general river pebble is about 7), the water absorption rate is ≤0.01%, the self-wear is ≤0.015%, and the rebound height after free falling from a height of 80cm to the polished floor tile surface is not less than 40cm (the general river pebble Its height does not exceed 20cm) (see figure 2 ).
Embodiment 2
[0033] Embodiment 2 The production of the application's stone cake product and contrast product
[0034] Production adopts the stone produced in the automatic stone cake production equipment described in CN 207411379 U and embodiment 1
[0035] Stone cake products for this application:
[0036] Kneading dough: take 800 parts of wheat flour, 200 parts of milk powder, and 200 parts of water, mix well and ferment naturally for 12 hours, add 100 parts of wheat flour, 80 parts of palm oil, 50 parts of eggs, 20 parts of salt, and sodium carbonate to the fermented dough 15 parts, 100 parts water, beating in water at about 40 degrees Celsius for 10 minutes;
[0037] Forming 1: The dough is automatically rolled and molded into a circular dough with a thickness of 2mm and a diameter of about 80mm;
[0038] Forming 2: use the production equipment in CN 207411379 U to bake stone cakes, the stone preheating temperature is 300 degrees Celsius, the baking temperature is 150 degrees Celsius...
Embodiment 3
[0043] Embodiment 3 crispness test
[0044] Since there is no standard characterization method for the indicator of crispness, the crispness of stone cake products is evaluated according to the following quantitative methods with reference to the practices commonly used in the industry and related literature:
[0045] Each stone cake sample is a round product with a diameter of about 80mm produced in the same production equipment;
[0046] The testing equipment uses the TA-XT2i physical property tester of British SMS company;
[0047] The HDP base of TA-XT2i is used for detection, and the stone cake erected is pressed down with the BSK probe along the diameter direction, and the force curve is analyzed with TA-XT2i's own software to obtain the number of space ruptures (times / mm, the ratio of the number of positive peaks to the distance) ) to characterize crispness, the maximum force corresponds to strain (the ratio of the distance corresponding to the maximum force to the she...
