Abstract
The invention discloses a kind of production method of package specific tekite sand, which belongs to quartzy finishing field；The present invention is equipment by producing encapsulation tekite sand to processes such as the broken of vitreous silica block, classification, magnetic separation using crusher, vibrating screen, magnetic separator using 10-20 millimeters of granularity of vitreous silica block as raw material；The production method include equipment investment is few, production cost is low, without sewage exhaust gas discharge, can be mass, the package specific tekite sand of high quality can be produced；Product is that semiconductor integrated circuit industry encapsulates the proprietary material used.
Description
Technical field
The invention belongs to quartzy finishing field more particularly to a kind of production methods of package specific tekite sand.
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 high grade quartz sand of choosing melts in electric arc furnaces, resistance furnace or high temperature sintering furnace, and melting temperature is 1800 DEG C -1900 DEG C and melts about
Become molten condition after 12 hours, become vitreous silica after cooling, due to its atomic structure longrange disorder, three-dimensional structure is intersected
It is low using temperature height, thermal expansion coefficient that link can be such that vitreous silica has, and does not react with other materials under room temperature, wear-resisting property
Good, hardness is higher, high temperature resistance is strong, and light transparent refractive performance, piezoelectric property are excellent.Encapsulation is with the specification of tekite sand
1.5-3.0 millimeters, appearance is white or translucent crystalloid, its main feature is that SiO2 content is 99.99% or more；Produce the production
Product are process using 10-20 millimeters of granularity of vitreous silica block as raw material by series of process such as broken, screening, magnetic separation,
The major advantage of the technique is: device therefor is few, investment is small, without toxic and harmful gas and liquid discharge, good product quality, can criticize
Amount produces and produces the package specific tekite sand of high quality.
Summary of the invention
Present invention mainly solves the problem of be to provide the production method of package specific tekite sand a kind of, this method is with grain
The vitreous silica block of 10-20 millimeters of degree is raw material, and encapsulation tekite is produced as equipment using crusher, vibrating screen, magnetic separator
Sand.
The present invention can be achieved through the following technical solutions:
It (1) is that 10-20 millimeters of vitreous silica blocks feeding crushers are crushed by specification, being crushed the time is 0.3-0.4 hours,
Broken all particles, which are sent into, carries out sifting vibrating sieve, and removal is greater than 3 millimeters and the quartz sand less than 1.5 millimeters, obtains
1.5-3.0 the quartz sand of millimeter.
(2) 1.5-3.0 millimeters of quartz sand is sent into magnetic separator, magnetic, metalliferous will be contained using the magnetic field in magnetic separator
Quartz sand carries out separation removal, and the magnetic separation time is 0.35-0.40 hours, obtains glass sand encapsulation tekite sand.
Preferably, the vitreous silica block is high-quality, high-purity vitreous silica block, and SiO2 content is miscellaneous 99.99% or more
Matter content is lower than 0.001%.
The beneficial effects of the present invention are: providing a kind of production method of package specific tekite sand, which is included
Equipment investment is few, production cost is low, discharges, can be mass without sewage exhaust gas, can produce the package specific melting of high quality
Quartz sand；Product is that semiconductor integrated circuit industry encapsulates the proprietary material used.
