Acid cleaning is a key link in the purification of high-purity quartz placer, especially in the preparation of high-purity quartz sand raw materials for glass manufacturing. This process mainly makes use of the characteristic that quartz is insoluble in acid, while other impurity minerals can be effectively dissolved by acid solution, so as to realize the purification of quartz. Common acids include hydrofluoric acid, * * *, hydrochloric acid, oxalic acid and * * *, etc. The specific acid concentration depends on the type and content of impurities in quartz sand. In the process of treatment, pickling wastewater is a major treatment focus, which includes pickling sediment, deacidification wastewater, tank washing wastewater, dehydration wastewater after washing, and filtration wastewater from quartz sand storage

The traditional thermal insulation materials rely on the principle of static air, and its obvious advantage is that low thermal conductivity can effectively reduce heat conduction loss. However, the obvious disadvantage of such materials is that they have voids inside and lack good waterproof, moisture-proof, anti-corrosion and oxidation resistance characteristics, so they are not suitable for environments with high permeability such as liquid, steam, underground, acid alkali dissolved gas and liquid. In order to make up for these shortcomings of traditional thermal insulation materials, Beijing Zhisheng Weihua Chemical Co., Ltd. has successfully developed ZS-111 waterproof, anti-corrosion, thermal insulation coating based on long-term experience in research, development and application of thermal insulation coating. This paint can withstand temperature up to

Zhisheng Weihua has successfully developed a series of high-end thermal insulation coatings through in-depth research on three basic ways of heat exchange - heat conduction, heat convection and heat radiation, providing more efficient energy-saving materials for the public and industry. Thermal insulation coating, which is a chemical polymer energy-saving material, can effectively prevent external heat from entering the interior of the object and maintain a constant internal temperature after its surface is painted. But this is only part of its principle and application. Let's explore different types of thermal insulation coatings and their applications in detail: first, thermal reflective thermal insulation coatings, whose coatings have excellent visible light and infrared reflectance, can transfer the light carrying heat

Ozone, with chemical formula of O3, is a special form of oxygen. Although its molecular weight is only 47.998, it contains huge energy. It has strong oxidation, which is very rare in the chemical world. Compared with oxygen, ozone shows a stronger oxidation capacity, which can play a role even at lower temperatures. Its strong oxidation makes ozone widely used in many fields. As an efficient bleaching agent, ozone can quickly remove organic pollutants in water, and decompose into oxygen after reaction, which will not cause secondary pollution to the environment. This makes it in industrial sewage, pharmaceutical wastewater, petrochemical wastewater, etc

Magnesium reduction tank plays a vital role in the smelting process of Pidgeon process. Its working environment is extremely harsh. It has been under high temperature, high negative pressure and oxidation environment for a long time, which leads to the frequent reaction of metal elements on the tank wall, which is then oxidized and corroded, and finally scrapped due to insufficient strength. This short life phenomenon not only causes a lot of steel waste, but also affects the long-term stability of production. In order to solve this problem, ZS-822 composite ceramic high-temperature anti-corrosion coating developed by Zhisheng Weihua Group has shown remarkable effect. The coating has been successfully applied to the inner and outer walls of the reduction tank after field coating test, significantly extending the

Corrosion prevention of pickling tank plays an important role in ensuring continuous and safe production of photovoltaic quartz sand. In the pickling process, the mixed acid solution used, such as * * *, * * * and hydrofluoric acid, has strong corrosivity and oxidizability. Especially in the high-temperature environment, these acid solutions put forward almost harsh requirements for anti-corrosion materials. Especially hydrofluoric acid, in which the fluorine ion has a small radius and strong permeability, makes the impermeability of anti-corrosion materials face a big test. Although there are a variety of anti-corrosion materials on the market, their performance in relieving reaction and anti fluoride ion penetration is often not as good as

In the field of combustion technology, energy-saving technology plays an important role. Among them, high temperature air combustion technology and oxygen enriched combustion technology are particularly outstanding, which are better than many industrial furnaces. The oxygen enriched combustion technology realizes multiple advantages such as reducing exhaust heat loss and increasing flame temperature by increasing the gas with oxygen concentration higher than 21% to participate in combustion. However, this technology also brings about the problem of uneven temperature field in the furnace and regional temperature. In order to solve this problem, it is an effective solution to paint ceramic infrared coating inside the furnace. High temperature far-infrared radiation coating ZS-1061, with its high temperature resistance, strong radiation rate

In order to prevent the electrolyte from corroding the outer wall of the storage tank, a series of anti-corrosion measures need to be taken. For metal storage tanks, surface treatment can be carried out to improve their corrosion resistance. For example, the metal surface is sprayed with strong acid oxidation resistant heavy anti-corrosive paint, ZS-1032 strong oxidation resistant anti-corrosive paint. The coating can form a protective layer to prevent the electrolyte from directly contacting with the metal, thus reducing the occurrence of corrosion. In addition, attention should be paid to the sealing of storage tanks. Ensure good sealing performance of the tank to avoid electrolyte leakage, thus reducing the risk of corrosion. The corrosivity of electrolyte for lithium ion battery is one of the most important factors
