How are glass balls made?

The ornamental value of the crystal ball is very high, so the asking price is also high. A good crystal ball of 10cm costs 10,000 to tens of thousands of yuan. Driven by economic interests, unscrupulous businessmen often use glass balls to pretend to be crystal balls in order to obtain huge profits, and they will make you hooked with rhetoric. In this case, when consumers can’t figure out whether they are true or not, they can distinguish true from false with just one strand of hair without equipment. The specific operation is to place a hair strand on a piece of white paper, and then carefully press the sphere on the hair strand, continuously rotate the sphere and carefully observe the changes of the hair strand through the sphere. If the hair strand has a double shadow, it is a crystal The ball, if the double shadow can not be seen in any direction when the sphere is rotated, it is a glass ball. This is because crystal is a heterogeneous body with double refraction, while glass is a homogeneous body with single refraction. When it is determined that it is a crystal ball, the above method should be used to distinguish between natural and synthetic crystal balls, because the price of natural crystal balls and synthetic crystal balls of the same size is very different. 1. High dismantling and good flowability. Because hollow glass microspheres are small spheres, they have better flowability in fluid rosin than flake, needle or irregular shape fillers, and thus have excellent filling performance. More importantly, this kind of small microbeads are isotropic, so there will be no inconsistency in the shrinkage rate of different parts due to orientation, which ensures a stable proportion of the product and does not warp. 2. Heat insulation, sound insulation, insulation and low water absorption rate. The hollow glass beads are thin gaseous inside, so it has the characteristics of sound insulation and heat insulation, and is an excellent supplement for various heat insulation and sound insulation products. 3. High specific internal resistance and extremely low water absorption make it suitable for polishing and producing cable insulation materials. 4. The color is pure white. How are glass balls made? The raw material for making glass balls can only be glass. Glass is industrially produced. The raw materials are mainly quartz sand, feldspar, calcite, Glauber's salt, etc. These ores must be heated to more than a thousand degrees before they can react to form molten glass. The diameter of the glass pinballs usually played by children is about 1 cm. Its production method can explain the problem: The raw materials for glass balls are mostly natural ores. Therefore, to make glass balls, all kinds of ores must be crushed and added into powder. Then, according to the composition of the glass, a batch is made and sent to a glass melting furnace for melting to form a molten glass. The qualified molten glass flows through the feeding tank and flows out from the feeding port to form strands. The temperature of the material strands is generally 1150~1170℃ for medium-alkali glass balls and 1200~1220℃ for alkali-free glass. The material strands are cut into ball embryos nearly 200 times per minute. The ball embryo passes through the chute, the ball divider, and is moved by the ball divider plate, rolls into different hoppers, and then falls into the ball groove formed by three rollers with the same rotation direction. The ball embryo is on the roller. The rotation and its own surface tension gradually form a smooth and round glass ball.
