Precipitated Calcium Carbonate
Uses: Can be used as filler in rubber, plastics, paper, paint and ink industries. Widely used in organic synthesis, metallurgy, glass and asbestos production. It can also be used as a medium seeding agent for industrial waste water, a antacid for stomach and duodenal ulcers, a detoxifying agent for acidosis, a SOâ‚‚ eliminating agent in SOâ‚‚-containing exhaust gas, a dairy cattle feed additive and an anti-sticking agent for oil felt . It can also be used as a raw material for tooth powder, toothpaste and other cosmetics.
Usually used as a filler, widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc., as a filler to increase products The volume is reduced, and the production cost is reduced.

There are many types of cutting technology, such as hobbing, grinding, gear shaping, shaving and so on. In the hobbing process, the length of the common normal is changed due to the eccentricity of the machine tool worm wheel, and the tooth profile of the gear is cut by the cutting edge of the hob cutting edge. The cutting edge deviates from the spiral surface of the basic worm and the base section and the tooth profile error occur. According to statistical analysis, the deviation of the base of the cut gear is 80, and the tooth profile error is 60 due to the manufacturing error of the hob. In the grinding process, the pitch error is generated due to the indexing mechanism error.
Adopting the gear shaping process, the gear insertion error is mainly the eccentricity of the indexing worm wheel mounted on the spindle by the gear shaping cutter, which has a great influence on the variation of the gear common normal length and often produces an out-of-tolerance phenomenon. The gear should specify ΔFw. For the small size gears that are commonly used in the shaving process, there is no forced movement between the shaving cutter and the shaved gear, which will cause the distortion of the front and rear gears of the shaving, such as the △Fr before shaving is converted into △ Fw. In addition to the shaving process, such as caries, grinding teeth, cold-rolled and hot-rolled gears, there are similar conversion rules for the anti-explosion electric drum shaving error.
Different inspection groups should be selected for different cutting processes. Gear geometry size (diameter, modulus) The gear with small diameter can be placed on the instrument for measurement. In this case, the gear mounting reference (fit hole) can be used as the measurement reference to measure the error with respect to the gear reference axis. For the project, it is also easier to achieve comprehensive measurement of gears.
Light Calcium Carbonate is made of limestone, and can be used in daily chemical products such as tooth powder, toothpaste, cosmetics, etc. It can also be used in organic synthesis, metallurgy, glass and asbestos production.
The particle size of light calcium is smaller than that of Heavy Calcium Carbonate, the oil absorption is larger than that of heavy calcium carbonate, and the price is higher than that of heavy calcium carbonate. They are all commonly used fillers in latex paint, and they are best used together. Light calcium is better in terms of sedimentation, but its oil absorption is greater than that of heavy calcium, and the price is generally more expensive than heavy calcium. Although it is not as stable as heavy calcium, it is stable. Even for exterior wall paint, its application amount is also very large. of.
