Description

Novel silicon dioxide microbead spheroidizing equipment and spheroidizing method thereof

Technical Field

The invention relates to the technical field of production of silicon dioxide microbeads, in particular to novel spheroidizing equipment and a spheroidizing method of silicon dioxide microbeads.

Background

Silica has both crystalline and amorphous forms. Silica such as quartz, quartz sand, etc. existing in nature are collectively called silica. Sand is a fine grain of quartz mixed with impurities. The opal and diatomite are amorphous silica. Silica is mainly used for manufacturing glass, water glass, cement and the like, and common stones are mainly composed of silica and calcium carbonate.

Silica can be reduced by coke, magnesium, etc. at high temperatures. At normal temperature, the strong alkali solution and SiO2 will react slowly to produce silicate, and the silica has important use in daily life, production, scientific research, etc, including silica microsphere.

Silica microspheres refer to spherical particles having a diameter of 0.1mm or less, and such spherical particles are classified into two types, i.e., crystalline silica microspheres and amorphous (glassy) silica microspheres, which have different spheroidization temperatures. The spheroidization temperature of the crystalline silicon microspheres is generally more than 1500 ℃, and the spheroidization temperature of the amorphous silicon microspheres is more than 1800 ℃.

When the content of the spherical silica contained in the filler of the plastic package material is higher, namely the content of the silica microspheres is higher, the filling property, the fluidity and the insulating property of the plastic package material are improved, the thermal conductivity and the mechanical strength of a packaged device are finally improved, the thermal expansion rate and the moisture absorption rate of the packaged device are reduced, and the damage to an integrated circuit during packaging is reduced. Therefore, spherical silica is often used as a filler in high-end molding compounds, and in order to produce silica microspheres, silicon microsphere spheroidizing equipment is generally adopted at present, and the related structure is basically sound.

The existing silicon microsphere spheroidizing equipment adopts a vertical arrangement. The silicon micro powder is added into the spheroidizing equipment from top to bottom by oxygen, and the flame also from top to bottom. Because the high-temperature flue gas is upward and is just opposite to the direction of flame, the probability that the particles in a plastic state in the high-temperature airflow collide with each other is greatly increased, and in order to solve the problem, the power of an induced draft fan is only greatly increased, the high-temperature particles are extracted under the working condition of high negative pressure, and therefore great heat loss is caused. The technology is originally sourced from abroad sixty years ago, the patent is wasted, and the technology is still used in China at present in a large amount.
