barium sulfate and ultrafine barium sulfate difference in the end where?


We are also called sodium sulfide, alkali sulfide, also known as smelly alkali, smelly soda, yellow alkali, alkali sulfide. How is such a product formed, and how is it that barite powder is used as a raw material in the production of barium sulfate to produce large amounts of sodium sulfide? With this problem we entered the efficient process of producing precipitated barium sulfate, because the sulfuric acid produced by the chemical reaction will produce some other by-products in the reaction. Pure sodium sulfide is a colorless crystalline powder. Strong moisture absorption, soluble in water. The aqueous solution is strongly alkaline. It can cause burns when touching skin and hair.



Sodium sulfide is commonly known as alkali sulfide. Aqueous sodium sulfide will slowly oxidize in air to sodium thiosulfate, sodium sulfite, sodium sulfate, and sodium polysulfide. Due to the rapid formation rate of sodium thiosulfate, the main product of oxidation is sodium thiosulfate. Sodium sulfide deliquescence in the air, and carbonation and metamorphism, constantly release hydrogen sulfide gas. Industrial sodium sulfide is pink, brownish red and khaki because it contains impurities. Its color is unique to its formation in the production, not we can control, we should use its maximum chemical characteristics for our service, in printing and dyeing, mineral processing, leather application can explain this problem.


For the production of industrial grade sodium sulfide price, regardless of the price of high and low, the quality of good and bad, it is mainly our use in printing and dyeing and leather, but if this product is eaten into the stomach, what will be the consequences of that? This product can decompose hydrogen sulfide in the gastrointestinal tract, and can cause hydrogen sulfide poisoning after oral administration. Corrosive effect on skin and eyes. Environmental hazards: harm to the environment.



How to make us treat alkali sulfide manufacturers correctly in our daily life, or to minimize the damage of sodium sulfide to us, crystalline sodium sulfide is a strong alkaline corrosive product. Anhydrous sodium sulfide is a pyrophoric item. Crystalline sodium sulfide reacts with acids to give off toxic and flammable hydrogen sulfide gas. Slightly corrosive to most metals. When burning, sulfur dioxide gas is released, and sodium sulfide powder can form an explosive mixture with air. Alkali sulfide is easily soluble in water, and the aqueous solution is strongly alkaline, and it is extremely irritating and corrosive when in contact with skin and mucous membranes. Compared with ultrafine barium sulfate, no matter sodium sulfide enters the industrial field or enters our other industries, its purpose to solve the problem is unchanged, and it also provides a better reference and basis for our future application in the industry.


The most advanced production process of precipitated barium sulfate in China is the calcination method, which is mainly made of barite as raw material and produced by more than ten technological processes. A large number of raw materials or fillers used in paints, inks, plastics, advertising pigments, cosmetics and batteries are used as fillers and reinforcing agents in rubber products. Polychloroethane resin is used as fillers and weighting agents, and surface coating agents for printing paper and copper board paper, sizing agents for the textile industry. Glass products are used as a fining agent, which can defoaming and increase gloss.


China's most famous ultrafine barium sulfate can achieve 5000 mesh, relying on the principle of ultrafine use a large number of powder coatings, paint, marine primer, ordnance equipment paint, automotive paint, latex paint, interior and exterior wall architectural coatings, can improve the product light resistance, weather resistance, chemical and electrochemical corrosion resistance and product decoration effect, enhance the impact strength of the coating. Relying on the advantage of price, ultrafine barium sulfate is seen and used by people in most industries, and it is a product that we should promote in large quantities.

Yuan Lei's Little Knowledge | Performance Requirements and Types of Fillers for Coatings


Fillers in coatings are usually white or slightly colored pigments with a refractive index less than 1.7. It has the basic physical and chemical properties of pigments used in coatings, but due to its refractive index being similar to the film-forming material, it is transparent in coatings and does not have the coloring and covering power of coloring pigments. It is an indispensable pigment in coatings.

Yuan Lei's Little Knowledge | Application Effects of Different Mineral Powder Materials in Coatings


In architectural coatings, commonly used mineral materials include barium sulfate, calcium carbonate, kaolin, mica powder, talc powder, quartz powder, silica micro powder, transparent powder, glass powder, wollastonite powder, etc. Reasonable application of various mineral materials can effectively improve or enhance the performance of coatings. Let's take a look at the application of different mineral materials in coatings.

Yuan Lei's Little Knowledge | Characteristics of Mineral Materials


Mineral materials refer to the material products obtained by processing and transforming natural minerals (mainly non-metallic minerals) or rocks as the main raw materials, or minerals or rocks that can be directly used as materials and aim to utilize their main physical and chemical properties. This meaning mainly includes the following four aspects: first, natural minerals and rocks that can be directly utilized or processed to be utilized; Secondly, finished or semi-finished materials made mainly from natural non-metallic minerals and rocks through physical and chemical reactions; Thirdly, artificially synthesized minerals or rocks; Fourthly, the direct utilization targets of these materials are mainly their own physical or chemical properties, not limited to individual chemical elements.
