• Influence of different nonmineral powders on the rheological properties of fluids

    Test results show that: viscosity comparison, nano-calcium > heavy calcium carbonate > low oil-absorbing activated calcium. 1, generally the finer the powder, the higher the oil-absorbing value, the higher the viscosity, by the nano-calcium particle size between 60-100nm, has an excellent thickening effect, can effectively improve the stability of the fluid; 2, at the same time, as can be seen above, low oil-absorbing active calcium viscosity rate slower than the heavy calcium carbonate, that is, in the same proportion of its viscosity is smaller, and the other by the right figure can be seen in the high proportion of low oil-absorbing active calcium in the addition of a certain amount of shear viscosity effect, similar to the rheological properties of talcum powder, with the production and construction of a friendly features; 3、At the same time, generally with the different additive ratio of the powder filler, the system viscosity will also appear different changes, the follow-up Division I will start a new share for this.

  • Analysis and evaluation method of surface modification effect of powder (Part 1)

    In recent years, surface modification is one of the most active and fastest developing technologies in the field of non-metallic mineral powder processing, and it is also an important means to improve its application performance, expand the market and consumption. Therefore, it has received much attention from the non-metallic mineral powder industry and downstream application industries.

  • Talcum Powder in Paints

    As a natural mineral with many excellent properties, talc is widely used in coatings and paints. It can improve the quality and performance of substances and reduce the production cost, therefore, talc will be more and more widely used in the manufacture of coatings and paints in the future.

  • Application and role of talcum powder in paper

    Talc at room temperature is a white powder, with a certain degree of smoothness and stability, its density of about 2.7g/cm³, melting point of 1390 ℃, heated to 800 ℃ above the decomposition of magnesium oxides and silica. In addition, the particle size of talcum powder is usually between 1-20 microns, with good dispersibility and plasticization, plays an important role in paper.

  • Talc masterbatch in polypropylene applications

    Polypropylene (PP) is made of propylene as the main component in the catalyst under the action of the product of addition polymerization, because of its excellent mechanical properties, non-toxic, heat, chemical resistance and easy processing properties, and raw materials from a variety of sources, low prices, so it is widely used in a variety of fields, to become a general group of five of the fastest-growing varieties of synthetic resins.

  • Application of inorganic fillers in rubber industry

    The rubber industry is currently called more complex, the original rubber only refers to natural rubber or synthetic rubber, but there are also some elastomers called rubber. Rubber in modern industry because of its large pollution, many conventional rubber products have been gradually replaced, but many such as tires, conveyor belt and other rubber products, still have not found a suitable alternative products, rubber materials are widely used in automotive products, footwear, conveyor and other industries.

  • Application status of talc powder in coatings

    In recent years, due to the production of more fine-grade talc grinding equipment, talc powder has smoothly entered the application of water-based coating systems, and is currently used in a variety of priming, intermediate coating, road marking paint, industrial paint, as well as internal and external architectural coating, due to the soft texture of talc powder, good dispersion, suspension, in the coating industry filling material occupies a large proportion.

  • Application of modified calcium carbonate in adhesive

    Adhesive is generally made of bonding material (matrix resin), curing agent, toughening agent, diluent and filler, etc. It is widely used in packaging, electronic and electrical appliances, building materials, automobiles and transportation, machinery manufacturing, new energy, medical health, aerospace and other fields.

  • Application of talc masterbatch in polyethylene blown film and ABS resin

    The lamellar structure of talc makes certain properties of talc-filled plastics greatly improved, and talc is a reinforcing filler in plastics. First of all, talc can improve the stiffness of the filler material and creep resistance at high temperatures. When the talc particles are arranged along the direction of material flow during processing, according to the principle of least resistance, the arrangement is basically flaky, from small pieces of refining into large pieces. Thus, it can significantly improve the material stiffness in a specific direction. Secondly, talc can significantly improve the filler material heat resistance. Used to measure the heat resistance of the material heat distortion temperature refers to the specimen under a certain load bending to a certain degree of temperature, sheet talc in a specific direction to improve the thermal deformation temperature of the material.
