The manufacturer of calcium hydroxide explains the specific advantages of the product
Calcium hydroxide, also known as carbon dioxide absorbent, is slaked lime produced by calcium hydroxide manufacturers. It is a white powdery solid. It is mainly used for compressed oxygen self-rescuer, positive pressure oxygen respirator and other rescue equipment to absorb the carbon dioxide exhaled by miners.
The application of calcium hydroxide produced by calcium hydroxide manufacturers Calcium hydroxide is suitable for sewage treatment, power plant desulfurization, paint filler, putty powder filler, chemical industry, paint and other new building materials. Calcium carbonate, concentrates, disinfectants, acid stimulants, astringents, hard water softeners, soil acidity inhibitors, depilatory agents, buffers, neutralizers, curing agents and drugs; used in rubber and petrochemical additives, such as It is added to lubricating oil in the petroleum industry to prevent coking, sludge deposition, neutralization and anticorrosion.
Advantages of calcium hydroxide produced by calcium hydroxide manufacturers:
1. The whiteness is blue and white, and the appearance is good;
2. No impurities, high purity;
3. Good solubility, no precipitation, the solution will drip after standing for more than a month, shake gently;
4. After soaking in water, it is smooth and has good processability, which is unmatched by ash calcium produced in other places.
Calcium hydroxide product index:
1. Whiteness: >90 degrees;
2. Fineness: >325 mesh;
3. Calcium content: >95%;
4. Moisture content: <2%.
Currently, the calcium hydroxide production method produced by the existing calcium hydroxide manufacturers mainly uses lime as raw material, which is calcined to obtain calcium oxide, and then crushed, boiled, filtered, and dehydrated to obtain calcium hydroxide, but the energy consumption of calcination is too high and the productivity is low , and the obtained calcium hydroxide is not graded, and further sorting is required, and the process is cumbersome.
The calciner adopts a gas kiln and is completed by a drying device. The drying device includes: an outer cylinder and an inner cylinder, and the inner cylinder is provided with a rotating shaft for driving the rotation of the inner cylinder. There are several intermediate cylinders with sieve holes, and the outer cylinder and inner cylinder are divided into filter residue layer and several sorting layers from inside to outside. The bottom of the cylinder is closed, and the bottom of the sorting layer is provided with a collection tank, and there is a gap between the collection tank and the outer cylinder and the middle cylinder; the exhaust gas generated by the gas-fired kiln first preheats the crushed materials at s, and then guides them into the inner cylinder. cylinder.
The calcium hydroxide production line adopting the above-mentioned calcium hydroxide production process includes a crusher, a calciner, a digestion reactor, a filter dehydrator and a drying device in sequence, and the raw materials pass through the crusher, the calciner, and the digestion reactor. , and filters. The exhaust gas produced by the calciner passes through the crusher and drying device in sequence.
The limestone raw materials produced by calcium hydroxide manufacturers are crushed in s1, calcined in s2, digested in s3, filtered in s4, dehydrated in s5, dried in s6 and sorted in s7 to obtain finished calcium hydroxide powders of different fineness. Reduce calcination time and increase yield; digest after calcination, separate solid calcium oxide from other solid impurities, filter to remove impurities, obtain a relatively pure calcium hydroxide solution, and then process calcium hydroxide solution. Calcium hydroxide powder is obtained by dehydration and drying, and its purity is higher than that of ordinary processes, and then separated to obtain calcium hydroxide powder of different fineness.
