Modificação de superfície

In recent years, surface modification technology of powders has attracted more and more attention. Surface coating modification is one type of surface modification. Coating, refers to wrapping inorganic or organic matter on the surface of particles to achieve the purpose […]

Barite is the most common mineral of barium, and its main component is barium sulfate. It is usually white and shiny, but it may also appear gray, light red or light yellow due to impurities. Barite has stable chemical properties,

Powder coating modification is a process in which surface modifier does not chemically react with particle surface, but the surface modifier and the particles are connected by van der Waals forces. This method is applicable to the surface modification of

Powder is a collection of many small particles. It has many discontinuous surfaces, with large specific surface area. The particle size is generally less than 1000μm. Powder has some physical properties, such as: fluidity, filling, cohesion and charge-ability. Powder fluidity is the basis of powder

Calcium carbonate is an inorganic compound with chemical formula of CaCO₃. It is the main component of limestone and marble, and it is widely used in industries of paper-making, metallurgy, glass, alkali, rubber, medicine, pigment and organic chemistry. Surface modification

1. Introduction Barite, as an important non-metallic raw material mineral, is mainly composed of barium sulfate (BaSO4). With  characteristics of being insoluble in water, high density, good filling capacity and non-toxicness, barite has shown extremely high application value in many fields. 2.

Reasons for calcium carbonate modification Calcium carbonate is one type of filling materials with multiple functions. It has characteristics of affordable price, high stability, pure color and non-toxicity, and it is widely used in fields of plastics, rubber, paper-making, building materials and wires and

1. Introduction The powder industry is an important basic raw material industry. Powder manufacturing technology occupies a very important position in chemical industry and material industry. In some polymer material industries and polymer composite materials, inorganic mineral powders are usually used as

Carbonato de cálcio leve também é chamado de carbonato de cálcio precipitado, ou cálcio leve para abreviar. Sua fórmula molecular é CaCO₃, e o peso molecular é 100,09. O carbonato de cálcio leve é feito pela calcinação de calcário para gerar cal e dióxido de carbono, então adicione
