Description
Technical field
The present invention relates to low iron-stone sand and purify field, generally refer to quartz sand in floatation process with the use of floating
Select medicament.It is specifically related to a kind of PPM level low ferrum glass sand floating agent.
Background technology
Glass sand generally refers to Si02Content 99.5%～99.999% silica flour, glass sand has fabulous
Chemical stability, high insulation voltage endurance capability and the extremely low coefficient of volume expansion, be photovoltaic glass, quartz glass, silica crucible, system
Make the primary raw material of silicon single crystal rod container.
China is one of country of enriching the most of quartz reserves, and exploitation utilizes quartz mine preferably to have Donghai Area, Jiangsu, Anhui
The ground such as Fengyang, Hong'an, Hubei, xiushui, Inner Mongol Wuhai, these quartz mine reserves are big, of high grade, easily exploit, but exploit at present
Most of quartz mines both function as and produce low-grade quartz ware: such as silicon powder, glass, refractory material, carborundum, ferrosilicon, molten
Melt quartz, quartz glass tube etc..
The domestic mineral resources that can be used for glass sand is a lot, but owing to processed means fall behind, product can not reach
The requirement of glass sand raw material, so that high grade ore is used as low-grade product, causes the serious waste of resource.
The domestic quartz raw material consumed that produces for quartz glass product of China, what the overwhelming majority produced is low and middle-grade products
Product, its medium-to-high grade electric light source quartz sand, silica crucible (polycrystalline, monocrystal silicon) quartz sand, quasiconductor and optical-fibre communications are used
Quartz raw material is still based on import quartz raw material.
In recent years, along with China's electronics and IT industry, the developing rapidly of electric light source industry, particularly solar photovoltaic industry
Growth, along with the fast development of domestic solar cell industry, it is contemplated that in the coming five years China's quartz glass industry will keep
The speed sustainable growth of more than 15-20%.
Producing high-quality quartz products, not only Technology wants advanced person, requires the highest to material purity.Present stage China
Produce the raw material Duo Shi import U.S. UNIMIN(You Niming of high purity quartz) glass sand of company, although its raw materials quality
Good, but price goes up again and again.Therefore improve quartz products quality and yield, promote the industrial development of HIGH-PURITY SILICON material, reach
High-end quartz raw material domesticizes, and is the instant thing of high purity quartz raw material production enterprise of China.
The prescription of PPM level low ferrum glass sand is the strictest, it is desirable to chemical analysis: SiO2(99.5%～
99.999%) , Fe2O3(1PPM～100PPM).In order to high efficiency, low cost produces satisfactory PPM level low ferrum high purity quartz
Sand, needs to set up floatation process production line, and with the use of the floating wash agent of high-efficiency low-pollution.
Glass sand is the primary raw material of quartz glass.Quartz glass is become " glass king " by people, because it has
A series of special physics, chemical property.It has excellent resistance to elevated temperatures, and temperature tolerance is up to 1100 ~ 1200 DEG C, and ratio is commonly
Glass is high 800 DEG C, and its fusing point is close with the fusing point of platinum (platinum).Coefficient of thermal expansion is minimum, and the evenly heat between 0～1000c is swollen
Swollen coefficient a-5.4 × 10-7, is equivalent to the 1/6 of pottery, is equivalent to the 1/20 of simple glass, mixes a certain amount of in quartz glass
Titanium, quartz glass have splendid spectral characteristic ' be possible not only to through visible ray, and infrared ray, ultraviolet can be passed through.Stone
English glass is good acid resisting material, is equivalent to 30 times of acid-proof ceramics, is equivalent to 150 times of rustless steel (nichrome).Stone
English glass is fabulous electrically insulating material, and its resistance is equivalent to 10,000 times of simple glass, and when 20 DEG C, resistivity is 1018 Q.
Cm, dielectric strength is 250KV/cm, and vacuum is up to (10-6Mpa).Because it is high temperature resistant, light transmission is good, good leak tightness, it is novel
The optimal material of electric light source, is also the optimal material manufacturing integrated circuit.
The major product of quartz glass includes: large scale integrated circuit high-purity high temperature resistant quartz glass tube, arc process stone
English crucible (solar level and semiconductor grade), optical communication quartz glass, electric light source quartz glass.All trades and professions are nearly all used
To quartz glass, but because of quartz glass product complex process, cost of material is expensive, and the price causing quartz glass is the most expensive, constrains
Being widely used of quartz glass.
