During this five-day and four-night trip to Xi'an, we not only tasted the authentic food, but also appreciated the historical flavor and humanistic style of the ancient capital; every attraction was unforgettable, and every moment was unforgettable.

CHINAPLAS 2024 will be held for 4 days It ends on April 26th!

On June 26-27, 2024, a two-member expert group from China Quality System Certification Center visited our company and conducted on-site audits of our quality management system, environmental management system and occupational health and safety management system. At the meeting, the head of the audit expert group introduced the purpose and basis of the audit, verified the scope of the audit, determined the audit plan, and explained the audit principles, procedures and practices.

As mentioned in the last issue, talc, diatomaceous earth, kaolin, fumed silica, etc. are functional fines specially used as matting agent, which belongs to inorganic filled matting agent. When the film is drying, their tiny particles will form a micro-rough surface on the surface of the film, reducing the reflection of light to obtain the appearance of matting. However, the matting effect of such matting agents is subject to the constraints of many factors.

Previously mentioned in the soft, now different industries for the increasing demand for transparent inorganic filler, transparent inorganic filler filler modified plastics, coatings and other industries, in order to meet the physical and chemical properties of the decline in the case of a small amount, but also has a good light transmittance.

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.

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.

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.
