탄산칼슘에 일반적으로 사용되는 표면 개질제 5가지는 무엇입니까?
Calcium carbonate is a water-loving inorganic compound. It has many hydroxyl structures on its surface. It has little affinity for organic polymers. It forms aggregates easily but disperses unevenly within them. This creates defects at the interfaces between composite materials. Direct application has poor results. These flaws become more obvious as the filling amount increases. […]
입자 밀도에 대해 얼마나 알고 계십니까?
Density is a crucial characteristic of powders (particles). It is widely used to evaluate the fluidity and compressibility of particles. This greatly impacts all parts of making drugs. For example, early product design depends on drug particle density. So do equipment selection and accessories. Specific drugs need the right disks and needles. They are used […]
분산 후 안료 입자를 안정적인 분산 상태로 유지하려면 어떻게 해야 할까요?
Pigment dispersion is the key to creating coatings. External forces cause the pigment to become fine particles. Then, it spreads evenly in the continuous phase to create a stable suspension. It requires resins, pigments, and solvents to function properly. It also requires a wetting dispersant. Dispersants improve dispersion and storage. It prevents pigment from settling […]
석영 모래의 산세척 효과를 향상시키고 황변 현상을 방지하는 방법은 무엇일까요?
High-purity quartz sand processing requires pickling. This is accurate under current mineral processing conditions. Pickling has various effects and functions. These are difficult to replace with water washing, flotation, or other methods. It can remove impurities. They are located on the surface of quartz sand particles. They are formed as inclusions or embedded within particles. […]
표면 개질이 필요한 분말은 어떤 종류인가요?
High-end powders that require surface modification are mainly inorganic powders and ultrafine powders. Here are specific examples and why: Inorganic powder Porous silica and silica powder are inorganic powders. They can increase their surface hydroxyl through surface modification. This enhances the hydration effect of the powder. It enhances their strength and is compatible with composites. […]
모래 분쇄기 vs. 볼밀, 제트밀!
The sand mill works by stirring together the grinding medium and the material. This is done by the high-speed rotating dispersion disc in a fixed cylinder. It causes strong shearing, scraping, and collisions. They are between the solid particles and the grinding medium. This achieves crushing, grinding, and dispersion. Sand mills can be divided into […]
