Description
[technical field]
The present invention relates to the modification of ore materials, particularly be the method for tourmalinite modification.
[background technology]
In recent years, along with the sustained and rapid development of China's economy, the people's standard of living is greatly improved, for the development of building and ornament materials industry provides the huge market space.But decorating and renovating material does not meet environmental requirement, the limit standard that surpasses the objectionable impurities of national regulation, cause the room behind the finishing can not move in for a long time, or move in the back HUMAN HEALTH is worked the mischief, and cause that the dispute of owner and developer, decoration company is continuous.
It is found that natural anion-generating material the eighties in 20th century, the wherein the most noticeable tourmalinite that surely belongs to.At present by in various building decorations, art work, adding tourmalinite and modified mineral powder thereof, with the release air negative ion, kill bacteria, decomposing harmful substances, release have begun to sell on market to the product of human body beneficial's far infrared rays, and have caused concern widely.But, consume a large amount of energy, and the releasability of negative ion is low, shortcomings such as tooling cost height because the restriction of prior art to the modification processing technology more complicated of tourmalinite, much will be used high-temperature firing.
[summary of the invention]
The method that the purpose of this invention is to provide a kind of tourmaline powder modifying, this method can strengthen the ability that the tourmaline powder powder material discharges negative ion, and simplify technology, reduce production costs.
A kind of method of tourmaline powder modifying comprises the steps:
F, grinding: the tourmaline powder of inciting somebody to action is ground to D
90≤ 5 μ m;
G, slurrying: the powder after will grinding with deionized water is modulated into slurry, and powder is 10%～50% with the slurry weight ratio;
H, modification: slurry is put into the ultrasonic machining groove, under 40～200kHz ultrasonic wave, shook 1～12 hour;
I, drying: the powder slip 100～200 ℃ of oven dry down, is sloughed the moisture in the slip;
J, grinding again: be ground to D again
90≤ 5 μ m can obtain the tourmaline powder of modification.
Further, among the method steps C of above-mentioned tourmaline powder modifying, preferred ultrasonic frequency 100～170kHz, 6～10 hours time.
Use the tourmaline powder of above-mentioned tourmaline powder modifying method preparation.
Tourmalinite method of modifying energy consumption of the present invention is low, and working method is simple, and modified effect is obvious, and can not introduce harmful heavy metal ion, radioactive substance makes property-modifying additive.
[embodiment]
The present invention introduces ultrasonic technique in tourmalinite material processing modified. the chemical effect that ultrasonic wave causes, mainly from cavitation effect and other non-linear phenomenas, expand and compression through ultrasonic wave radiating liquid medium cavitation bubble generation, produce the focus of localization, thereby cause the sonochemistry reaction in the liquid medium, for a heterogeneous solid liquid system, action of ultrasonic waves produces cavitation bubble in medium, produce microjet at solid surface, cause liquid at high speed to impact solid surface, cause the pitting and the localization heating of solid surface, the turbulent flow that causes because of microjet can be improved the mass transfer process between liquid medium and solid surface significantly. the formation of bubble in the liquid, collapse and consequent localized hyperthermia in growth and a few microsecond suddenly, high pressure. the temperature in gas-phase reaction district can reach more than the 5200K, the significant temp in liquid phase reaction district is about 1900K, and local pressure is 5.05 * 10
7More than the Pa, rate of temperature change is up to 10
9K/s is equivalent to provide TRANSIENT HIGH TEMPERATURE high pressure microreactor.This just provides very special physicochemical condition for the modification of tourmaline powder.Among the present invention, tourmaline powder is after accepting ultra-sonic oscillation, crystalline structure is more regular, the moment of dipole that structure cell has is arranged consistent more along same direction, make crystal be in the high degree of polarization state, thereby improve the self power generation intensity of field that produces around the crystal greatly, stronger with the compound ability of other material.
Main component of the present invention: tourmalinite, chemical general formula are NaR

Because the positive and negative charge-site of each structure cell of tourmalinite can't overlap, so two ends form positive pole, negative pole, constitutes a permanent electrode.Thereby make crystal be electriferous state, form 10 around
4～10
7It is the individual ball-types of tens μ m that the electric field of V/cm (crystalline size is 3 μ m), electric field action scope are radius.Water molecules (H
2O) in case after touching this material, because its electrostatic field can make water molecules on every side that electrolytic action takes place immediately, water molecules will resolve into the hydrogen ion (H that has positive electricity

The negative ion that discharges can neutralize, wrap up obnoxious flavour particles such as the positively charged formaldehyde of free, ammonia, benzene class, makes it become macroparticle group and precipitates, and no longer floating forms injury to human body in air.And have good go peculiar smell, sterilization and antimicrobial effect.
Because the tourmalinite that exists of moment of dipole has good far infrared performance, can produce 4～14 μ m, the far infrared rays of emittance＞90%.
Because the ultrasonic energy quantitative limitation, the change of tangible property takes place in the tourmalinite that is difficult to make particle diameter surpass 5 μ m, so the preferred D of the present invention
90The tourmaline powder of≤5 μ m is modulated into 10%～50% slurry with deionized water, puts into the ultrasonic machining groove, under 40～200kHz ultrasonic wave, shook 1～12 hour, then the powder slip is dried down at 100～200 ℃, slough the moisture in the slip, be ground to D again
90≤ 5 μ m can obtain efficient anion powder.Preferred ultrasonic frequency is 100～170kHz, and the concussion time is 6～10 hours.
For the content of better explanation this patent, the spy is described further with following example, but example is not that content of the present invention is made restriction.All use elbaite in an embodiment, ultrasonic generator adopts must believe 8500HF, and the negative ion generation all is at powder surface 2cm place, the data that record with DLY-4 type negative ion detector
Embodiment:
The tourmaline powder consumption is 1000g, and each embodiment, Comparative Examples preparation condition and gained data such as following table are listed:
| Tourmaline powder D 90(μm) | Deionized water (g) | Powder: slurry (weight ratio) | The slip bake out temperature (℃) | Ultrasonic frequency (kHz) | The concussion time (h) | Negative ion number/cm 3 | |
