The InfX talc analyzer EDX9000B plus is used for talc composition analysis

Black talc is a kind of silicate mineral, is the general name of black talc and gray black talc, its main chemical composition is silica (acerca de 69%) and magnesium oxide (acerca de 26%) 6, in addition to contains a small amount of potassium, calcium, hierro, sodium and other substances, black talc black is mainly due to the internal contains a small amount of organic matter caused by. Black talc is rich in resource reserves in our country. Actualmente, the proved black talc mining area is mainly distributed in the south-central region of our country and the southwest region. The main producing areas are Guangfeng of Jiangxi, Nantong of Chongqing, Baojing of Hunan, Jinta of Gansu, Jiujiang of Jiangxi, Yichun of Jiangxi, etc.. Entre ellos, Guangfeng black talc ore in Jiangxi Province is the largest black talc ore deposit found in China so far, with proven reserves of 1 billion tons, which is also the largest black talc mining area in the world. China’s black talc products in addition to meet the domestic market demand, but also exported to the United States, Japón, South Korea, the European Union, ASEAN and other countries and regions. The current market demand is strong, short of supply, the application industry is as follows:

Ceramics

Talc has good thermal stability and other physical and chemical properties, widely used in refractory materials, paper making, goma, insulating materials and other fields, black talc because of its head color is black, the chemical composition is relatively simple, a small amount of organic matter in the composition of 1100C high temperature heating conditions, organic carbon can be completely flammable removal, after ultrafine grinding can get high quality white ultrafine talc powder, Whiteness up to 90%, in ceramic production, can improve the thermal stability of ceramics, propiedades mecánicas, and to that number of insulation, protect the ceramic glaze is not easy to change color and crink and other characteristics, so widely used in the ceramic industry

Papermaking filler

Talc has its chemical stability, low hardness and other characteristics, added in the papermaking process, can increase the smoothness and tightness of the paper. Its lubricity can reduce the friction on the surface of the paper, reduce the adhesion phenomenon between the paper, and improve the effectiveness of the manufacturing process. The black talc can be calcined by high temperature white and other processes, so that it has the same characteristics as talc, and the price is low, also in line with the talc standard used in the paper industry (JC161-82).

Polymer filler

Polymer fillers use two types of black talc, one is calcined talc powder. Due to high temperature firing, the loss of crystal water, the layered crystal structure into a chain structure, the hardness increases, can be used in the need to improve the hardness and strength of plastic products. The other is black talc powder, which can be used directly in the production of black plastic. According to research, adding black talc powder (its total carbon black does not exceed 3%6) in the production of HDPE can improve the impact strength, adding black talc powder (its total carbon black does not exceed 5%6) can improve the tensile strength. Because black talc has the inherent characteristics of talc, has a certain hydrophobicity and good dispersion, and the compatibility with polymers is better than that of simple carbon black, so it has broad application prospects in improving polymer properties.

Building material coatings

Due to the hydrophobicity, low hardness and chemical stability of talc, it can be added to the coating to enhance the anti-wear and anti-corrosion effect of the coating. The sheet structure of talc makes it have good adsorption and rheology, which can improve many properties of the paint, such as preventing the paint from hanging and settling when it is painted and stored. According to the study found that the addition of 10% talc in the paint can improve the water resistance of the fireproof paint, adding 20% talc powder can enhance the heat insulation performance of the paint. And the coating with talc powder has higher brightness and smoothness in use. In developed countries such as the United States and Western Europe, the coating industry consumes more than 200,000 tons of talc per year. Black talc is calcined to remove organic matter and obtain talc powder that can be used in coatings.

Other Areas

Black talc due to small particles, through high temperature calcination has the characteristics of talc layer structure, and its low price, contains a lot of silicon elements, can block infrared rays, so it can enhance Rupin’s sunscreen and anti-infrared effects, so that it can be added to sunscreen or eye makeup and other cosmetics. Además, due to its chemical composition is low toxicity, but also has adsorption, can be used as a drug additive, so as to protect the skin and mucous membrane.In addition, the calcined black talc can also be used in paint, cable, medicamento, textil, wall and floor tiles and other industries, with considerable prospects

The content of silicon magnesium calcium iron in black talc will have a certain impact on its performance, of which silicon content has a great impact on its performance. Silicon is one of the main components of black talc, and is also one of the materials widely used in construction, electrónica, optics and other fields. Silicon can increase the hardness and strength of black talc, making it harder and more durable; Al mismo tiempo, it can also increase the corrosion resistance of black talc, making it more durable. Por lo tanto, the higher the silicon content of black talc, the better its performance. Secondly, the iron content of black talc also has a great impact on its performance. Iron is a key element in black talc, which can affect its color, hardness, density and other properties. Al mismo tiempo, iron can also increase the oxidation and reduction of black talc, making it more flexible and stable in chemical reactions. Por lo tanto, the right amount of iron content can increase the beauty and stability of black talc. Finalmente, the content of calcium and magnesium in black talc will also affect its performance. Calcium and magnesium are the two main elements in black talc, which can increase its toughness and durability. Al mismo tiempo, the high content of calcium 1 and magnesium can also affect the color and texture of black talc, making it more beautiful. Por lo tanto, the right amount of calcium and magnesium content has an important role in the performance and beauty of black talc. In summary, the composition content of black talc has a great impact on its performance. Appropriate amount of silicon, hierro, calcium and magnesium content can make black talc have more excellent performance and more beautiful appearance. Por lo tanto, when using black talc, we should pay attention to its composition content and choose the black talc material suitable for their own needs to obtain the best results.
