Abstract
The invention discloses a method for producing lightweight shale opal powder. The method comprises the following steps: carrying out magnetic separation on 80-325mesh lightweight shale opal powder, charging into a roasting box or a roasting tank after removing impurities, putting into a tunnel kiln to roast, and accurately grinding into 400-3,000mesh powder after roasting, wherein the roasting temperature is 580-1,000 DEG C, and the roasting time is 2-3 hours; carrying out secondary magnetic separation and purification again, and adding a modifier after purifying for 60 minutes and modifying for 12 hours to obtain the lightweight shale opal powder, wherein the ratio of the modifier to the lightweight shale powder in mass percent is (0.2-2) to 100 and the modifier is a titanate coupling agent, a silane coupling agent or an aluminic acid coupling agent. The lightweight shale opal powder produced by the method has high purity, simple production process and low production cost.
Description
Technical field
The present invention relates to a kind of production method of opal powder, specifically a kind of light shale is prepared the method for opal powder through removal of impurities, purification and roasting.
Background technology
Opal shale is a kind of country's two class rare mineral resources of in recent years finding, mainly, by cristobalite, phosphorus quartz, is only made up of a small amount of quartz and clay mineral.Cristobalite, tridymite are also changed and are formed by opal.
This kind of ore contains a large amount of Fossil Conchostracas at abundant lobe cheek class limnobios fossil, rarely found in Sedimentary Rock.Opal shale is evenly distributed, and has light weight, proportion (2:1 left and right) the low aluminium of high silicon, and active silica, without joint, laminated bedding, good integrity, water-absorbent is extremely strong.Reach 74.4% and water-intake rate does not reach and full close front shale and do not seem moist, percent of decolourization reaches 96%, the low 15g/cm of density
3, bulk density 0.98 g/cm
3, the loose porous of pore texture.Aperture forms amorphous amorphous body porous at physical environment, and porosity is high, specific surface area 105 m
2after/g-roasting, can reach 277.3 m
2/ g, is a kind of desirable, and inorganic materials is combined difficult friendly materials with organic materials.
The opal shale place of production and performance:
Opal rock originates from northeast Nenjiang, Xinjiang Bei Tun, the ground such as Jilin.Its main chemical SIO
2, H
2o is that one contains noncrystalline or colloid active silica.Ore is canescence, detects through national building materials department, nonpoisonous and tasteless, "dead", there is the tensile strength of enhancing flexural capacity, anti-impact force, as be added in plastics organic materials, can increase wear-resisting, resistance to bending, ageing-resistant, the material short period of time return function after depression bending.
Summary of the invention
Object of the present invention, is to provide a kind of production method of lightweight shale opal powder, and the lightweight shale opal powder purity that the method is produced is high, and production technique is simple, and production cost is low.
The technical scheme adopting is:
A production method for lightweight shale opal powder, comprises ore dressing, rinsing, pulverizing, magnetic separation, roasting, grinding, purification and modified technique step.Ore dressing and rinsing are known technology, it is characterized in that:

2) the 80-325 order lightweight shale opal powder of step 1 being made carries out magnetic separation, removes impurity, and magneticstrength is 18000-20000 Gauss.
3) after the light shale powder after the removal of step 2 magnetic is assorted is packed in roasting casket case or roasting pot, put into cellar for storing things, tunnel and carry out roasting, after roasting, refine to 400-3000 order powder.Maturing temperature is 580-1000 DEG C, and roasting time is 2-3 hour.
4) the lightweight shale opal powder after step 3 roasting is carried out again to magnetic separation for the second time and purify, magneticstrength is 18000-20000 Gauss, purifies 60 minutes, and whiteness reaches 85%, silicone content reaches >=and 90%.
5) add properties-correcting agent to carry out modification the light shale powder of purifying through step 4 magnetic separation for the second time, the mass percent of properties-correcting agent and light shale powder is 0.2-2:100(mass percent).Modification time is 12 hours, to obtain final product.Can be by setting metering packing, warehouse-in.Properties-correcting agent is titanate coupling agent, silane coupling agent, aluminic acid coupling agent.
Described properties-correcting agent comprises:
Opaline composition before and after table 1 roasting
Table one %
In table one, per-cent is mass percent.
The lightweight shale opal powder of producing by the inventive method, whiteness reaches 85%, and silicone content reaches 90%, and technique is simple, good energy-conserving effect, production cost is low.
