1.Category of Mineral Materials
Mineral materials generally refer to all kinds of materials. It includs powders and various types of products, which are prepared without destroying the crystal structure of non-metallic Minerals. With the development of technology and national economy, the non-metallic mineral industry has been extended from resource industry to new material industry, and its value has doubled and increased exponentially.
2.Functional Nonmetallic Mineral
Adsorption Function: Bentonite, sepiolite, attapulgite, diatomite, opal, expanded graphite, illite, Yimeng clay, expanded vermiculite, expanded Perlite, etc.
Fireproof function: Gypsum, expanded Perlite, asbestos, expanded vermiculite, expanded graphite, etc.
Release Of Negative Oxygen Ions: Tourmaline;
Fiber Reinforcement: Acicular Wollastonite, Asbestos, Fiber Sepiolite, Fiber Attapulgite;
REPLACEMENT OF SILICA REINFORCEMENT: illite, Montmorillonite, diatomite and so on;
3.Functional Nonmetallic Mineral
Medicinal Minerals: Gypsum, TALC, calcium carbonate, Montmorillonite;
Conduction: Graphite;
Insulation: Quartz, Mica;
ACID AND ALKALI CORROSION RESISTANCE: Quartz, Barite, etc.
Radiation protection: Barite.
Health function: Maifanshi, Yangqi Stone, tourmaline;
4.Selection of Functional Minerals
ADSORPTION FUNCTION:
DIATOMITE: Most organic matter and heavy metal ions, can not adsorb ammonia; resistant to high temperature, pickling, expensive transport distance
Bentonite: Most organic matter and heavy metal ions; after adsorption regeneration and application needs outlet; can inhibit bacteria; thickening
ATTAPULGITE clay, sepiolite: CIGARETTE, etc.
Expanded Graphite: Organic pollutants have special effects, including those used in oil spills
ZEOLITE: Molecular Sieve, the type of Zeolite adsorption of heavy metal ions have different effects. Note the hole size and the heavy metal ion size match.
HOW TO CHOOSE:
The properties of the target adsorbate match the pore size of our mineral;
The effect of Ph on the electrical properties of minerals and contaminants (generally, it takes a suitable pH value to deal with)
Before starting, pay attention to how the adsorption regeneration or treatment
5.Selection of Function Minerals
Electrical insulation: Large Piece of Muscovite; High Purity Silica powder, attention to defects
Fiber reinforcement: Wollastonite, sepiolite, various synthetic fiber
Thickening function: Attapulgite Clay, sepiolite clay, Bentonite Clay, Kaolin clay. High dispersibility and special particle shape. The less spherical the better;
Catalyst support: Zeolite, Bentonite, diatomite, attapulgite and so on
Requirements: ACID and Alkali resistance, high temperature resistance, porous, high purity.
It is usually refined first and then chemically precipitated
6.Mineral and Selection of Food and Frug Function
Calcium carbonate, Montmorillonite, magnesium carbonate, Zeolite, gypsum and so on.
Natural high purity, low content of heavy metals, low toxicity, less cristobalite (Montmorillonite)
Choose natural crystallinity is very high, no heavy metal around the ore body production enterprises (within 30 km)
All right, that's all for today, and then we'll have time to talk about any problems.
