What is Basic Zinc Carbonate?

Fundamental zinc carbonate is white amorphous powder with a loved one density of 4.42-4.45. Soluble in thin down acid and also alkali, somewhat soluble in ammonia and ammonium salt, insoluble in water, ethanol and also acetone. It decomposes into co2 as well as zinc oxide at 300 ° C. It reacts with H2O2 to release carbon dioxide and form peroxide. Fluorescence can occur when heated at 250-500 ° C for different amount of times as well as cooled down to room temperature. Its uses consist of: making latex film items, pigments, rayon, catalytic desulfurizer, and made use of as light astringent, antibacterial, disinfectant and also skin protection agent in medicine.

Use and Preparation Method of Basic Zinc Carbonate

When zinc touches with damp air having co2, a thick film will certainly be based on the surface to protect its inside from oxidation. This flick is standard zinc carbonate (ZnCO3 3Zn( OH) 2), fundamental zinc carbonate It is a tighter safety film. Response formula: CARBON DIOXIDE +4 Zn +2 O2 +3 WATER= ZnCO3 · 3Zn( OH) 2
. The all-natural essential zinc carbonate mineral is called “hydrozinc ore”. The chemical formula is ZnCO3 · 2Zn( OH) 2 · WATER. Molecular weight 342.15. White amorphous powder. The member of the family density is 4.42 ~ 4.45. Soluble in thin down acid as well as also antacids, slightly soluble in ammonia as well as ammonium salt, insoluble in water, ethanol as well as also acetone. It decomposes into co2 as well as zinc oxide at 300 ° C. It responds with H2O2 to release CO2 and kind peroxide. Fluorescence can take place when heated up at 250-500 ° C for different period as well as cooled to room temperature level.
Production method: Essential zinc carbonate is likewise called transparent zinc white. When zinc white ZnO is created by moist approach, its calcination temperature is controlled to produce it as a by-product. It is named as a result of the truth that it is a white clear powder. In industry, the soda ash service is consisted of in the zinc sulfate choice to create a white standard zinc carbonate accelerate. It is cleaned with water and additionally filtered to obtain the item. 4ZnSO4 +4 Na2CO3+ WATER → 3ZnCO3 · Zn( OH) 2 +4 Na2SO4+ CO2, in addition, it can additionally be prepared by steaming zinc carbonate with water.
Essential zinc carbonate usage: It can be taken advantage of to make latex movie items, pigments, rayon, as well as also catalytic desulfurizer. In medicine, standard zinc carbonate is made use of as a light astringent, preservative, baby powder, anti-bacterial and additionally skin protection representative. Considering that the visibility of basic zinc carbonate is close to that of all-natural rubber, it is made use of as a reinforcing representative along with vulcanization accelerator in clear rubber products.

Drying Method of Basic Zinc Carbonate

The traditional basic zinc carbonate drying method uses mostly coal, fuel oil or natural gas as the source of thermal energy. By burning these fuels, the basic zinc carbonate is dried directly or indirectly. This method often causes a lot of energy waste and discharges a large amount of carbon dioxide. Sulfur dioxide and other polluting gases are not conducive to energy conservation and environmental protection.

For example, some manufacturers of basic zinc carbonate use coal-fired boiler steam to dry basic zinc carbonate indirectly. It consumes 0.7 tons of standard coal for drying one ton of basic zinc carbonate products, and emits 2.6 tons of standard coal for each ton of standard coal burned. tons of carbon dioxide and 8.5 kg of sulfur dioxide. If a factory produces 3 tons of basic zinc carbonate per day, it needs to emit 5.6 tons of carbon dioxide waste gas and 18 kg of sulfur dioxide waste gas every day. Carbon dioxide and sulfur dioxide waste gas are the main reasons for the formation of haze weather, which deviates from the current energy conservation and environmental protection policies.

CN201410401834.3 proposes a kind of basic zinc carbonate drying device, which solves the problems of energy waste, waste gas emission and environmental protection in the basic zinc carbonate drying process in the prior art. The technical scheme of the present invention is achieved in that a kind of basic zinc carbonate drying device comprises: a drying chamber and a solar water heater, a drying bed is arranged below the drying chamber; It consists of a heat-conducting metal plate, a heat dissipation water pipe and a foam insulation board; the output end of the solar water heater is connected to one end of the heat dissipation water pipe through a hot water delivery pipe, and the other end of the heat dissipation water pipe is connected to the input of the solar water heater through a return pipe. end connection.

The working principle of the present invention is as follows:

Put the basic zinc carbonate material containing moisture on the heat-conducting metal plate of the drying bed in the drying room, and spread the material, and the outdoor sunlight radiates to the basic zinc carbonate material through the plastic film or glass on the top and surrounding of the drying room At the same time, under the action of the hot water circulation pump, the hot water in the solar water heater enters the cooling water pipe in the drying bed through the hot water delivery pipe, and the heat generated by the cooling water pipe is transferred to the alkaline type through the heat-conducting metal plate. The lower surface of the zinc carbonate material.

In this way, the upper and lower surfaces of the basic zinc carbonate material are heated and dried at the same time, and the wet steam generated during the drying process is discharged through the windows on the top and both sides of the drying chamber, which speeds up the drying speed.

After being cooled by heat conduction, the hot water in the cooling water pipe flows back to the solar water heater through the return pipe and is reheated. This cycle is repeated to continuously heat and dry the materials on the drying bed.

Since the basic zinc carbonate product is not high in temperature and does not decompose under sunlight, it will not change the quality of the product after drying.

Preparation of Basic Zinc Carbonate

A production method of basic zinc carbonate, comprising the following steps:

(1) secondary zinc oxide is added in the sulfuric acid solution, and the stirring reaction produces the zinc sulfate solution;

The chemical equation for the reaction between zinc oxide and sulfuric acid is:


During this reaction process, some by-products are generated, and the chemical equation of the reaction is:

PbO+HSO=PbSO↓+HO (PbSO is precipitated in the form of precipitation)





(2) adding potassium permanganate and zinc powder to the zinc sulfate solution for impurity removal, obtaining impurity removal zinc sulfate solution;

The addition of potassium permanganate can remove divalent iron ions and divalent manganese ions in the reaction solution, that is, remove FeSO and MnSO in the reaction solution. The reaction equation is:



MnSO reacts with potassium permanganate to form manganese dioxide precipitate, which removes manganese ions; FeSO reacts with potassium permanganate to form iron hydroxide precipitate, which removes iron ions;

(3) Add sodium carbonate aqueous solution to the impurity-removing zinc sulfate solution, and stir the reaction until the pH of the solution is 6.5-7.5 at a temperature of 50-55° C., and then continue at a temperature of 45-65° C. Stir the reaction for 0.5-1h;

The chemical equation for the reaction of zinc sulfate and sodium carbonate is:


When the pH of the solution reaches 6.5-7.5, then continue to stir and react for 0.5-1h at a temperature of 45-65°C, so that zinc sulfate and sodium carbonate can be fully mixed for reaction;

(4) Filter the reaction solution, wash the filter cake with purified water until the filtrate does not contain sulfate ions, dry the filter cake and pulverize to obtain basic zinc carbonate. Because basic zinc carbonate is insoluble in water, washing the filter cake with water can remove impurities soluble in water, that is, remove sulfate radicals.
