If the liquid ring vacuum pump chamber is not dry inside the state, in a long period of time, the pump chamber will rust. At this point, when we use it, it may not open, so we will rust. Schindler vacuum pump below to give you a brief introduction of two kinds of derusting methods.

1, manual rust

This measure is the most cost-effective insurance. Artificial rust, we can use their own tools to get rid of rust, our artificial rust, do not need to use other chemicals to rust, so save some costs. Why is insurance? Because the liquid ring vacuum pump cavity, if the chemical rust remover to rust, then pump more or less will be damaged.

2, with derusting rust

This measure is very clean rust but the pump chamber damage.

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.
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.
