Abstract
The invention discloses a kind of production method of gum filler silicon powder, which finishes field；The present invention is using high-quality high purity quartz block as raw material, gum filler silicon powder is produced by techniques such as broken, magnetic separation, two-stage grinding, classifications, the production method includes the gum filler silicon powder that equipment investment is few, production cost is low, discharges without sewage exhaust gas, can be mass out high quality, and product is mainly used as filler when rubber production.
Description
Technical field
The invention belongs to quartz finishing field more particularly to a kind of production methods of gum filler silicon powder.
Background technique
Vitreous silica is the amorphous state of silica, and the content of silica must not be less than 99.8%, and when production will be smart
The natural stone diamond stone of choosing is melted in furnace high-temperature, and melting temperature is 1800 DEG C -1900 DEG C, becomes molten after about 12 hours melting times
Melt state, become solid-state vitreous silica after cooling, vitreous silica have using temperature is high, thermal expansion coefficient is low, wear-resisting property is good,
The series of advantages such as hardness is high, light transparent refractive is good, piezoelectric property is excellent.The product of vitreous silica has: various specifications and difference
Tekite sand, vitreous silica block and the vitreous silica silicon powder of purposes.Vitreous silica silicon powder is by tekite diamond stone through broken
The silicon powder that the multiple tracks technique such as broken, magnetic separation, grinding, classification is process is a kind of nontoxic, tasteless, free of contamination inorganic non-gold
Belong to material, gum filler silicon powder is that a kind of granularity is a kind of special between normal melt silicon powder and ultra-fine melting silicon powder
It is used as the silicon powder of gum filler, in production because it is thinner compared with ordinary silicon powder size, is ground in production using increase level-one
Grinding process keeps product granularity thinner.The present invention is a kind of gum filler silicon powder, the content of silica 99.9% or more,
For granularity at 2-10 microns, which selects high-purity natural quartz, and through high melt, the vitreous silica block formed after cooling is carried out
Micro mist made of attrition process twice has many advantages, such as that purity is high, thermal expansion coefficient is small, low-activity, resistant to chemical etching, outside
Seeing is white powder, and bulk density is 200-250 kilograms per cubic meter, widely used.The present invention using high-quality high purity quartz block as raw material,
It is process by techniques such as broken, magnetic separation, two-stage grinding, classifications, the major advantage of the process flow is: simple process, nothing
The gum filler silicon powder that toxic and harmful gas and liquid discharge, can be mass and produce high quality.
Summary of the invention
Present invention mainly solves the problem of be to provide the production method of gum filler silicon powder a kind of, this method is with high-quality height
Pure quartz wedge is raw material, produces gum filler silicon powder by techniques such as broken, magnetic separation, two-stage grinding, classifications.
The present invention can be achieved through the following technical solutions:
(1) high-quality high purity quartz block is sent into broken crusher machine, obtains tekite sand of the diameter less than 3 millimeters.
(2) tekite sand is sent into magnetic separator, will be divided containing magnetic, the tekite sand containing metal and metal oxide
It leaves away and removes, the magnetic separation time is 0.3-0.4 hours.
(3) the tekite sand after magnetic separation is sent to grinder to grind, controls charging and the discharging speed of grinder
Equilibrium, keeping milling time is 2.5-3.0 hours.
(4) powder after the grinding of first order grinder, which is sent to second level grinder, is ground, milling time 1.5-
2.0 hours, vibrating screen is sent to be sieved after grinding, the biggish return second level grinder of granularity repeats to grind, and granularity conforms to
Ask the discharging of silicon powder.
Preferably, the granularity of the gum filler silicon powder is 2-10 microns.
The beneficial effects of the present invention are: providing a kind of production method of gum filler silicon powder, which is included
The gum filler silicon powder that equipment investment is few, production cost is low, discharges without sewage exhaust gas, can be mass out high quality, product
It is mainly used as filler when rubber production.
