The refined mineral is characterized by the borosilicate structure and the anomalous thermal-electro-piezo-physical effects—Tourmaline becomes excellent function additive which is capable of rendering remarkable effect of excellent properties on the composition materials. Hebei Province which abound in mineral resources is the production base of many new material industries. Hebei Hezhen Industrial Co., Ltd. have more than 60 engineers and technicians for the development and innovation of new material products of non-metallic minerals such as the high quality tourmaline powder for composites, etc. Below is the important reason why the manufacturers add tourmaline powder into their composites.
Generation of Negative Ions and Air Purification
The negative ions generating capacity of tourmaline are the most marvelous properties. As an additional compound for the composite material, tourmaline powder functions as a permanent natural power generator and is able to release natural negative ions from the electric field it generates. As a result, the overall product has functions for environmental remediation. Tourmaline composites used in decorative furniture paper have been shown to release approximately 1,000 negative oxygen ions per cm³, significantly improving indoor air quality. Negative ions in tourmaline/wood polyester composites showed the capacity to absorb smoke, bacteria and dust particles. It is therefore considered suitable for manufacturing composite for home decoration, wall covering or inside automobile use.
Antibacterial and Antimicrobial Protection
Aside from tourmaline's ability to produce negative ions to help purifying the air, tourmaline possesses a strong bacteriostatic action. In the research of tourmaline, its bacteriostatic action can be easily transplanted to another material. When a specific proportion of tourmaline was incorporated into carrageenan/tourmaline film food packaging, the inhibition zone of Staphylococcus aureus in the film increased to an average diameter percentage as high as 39.80%. Thus, incorporating tourmaline powder as an addition can significantly help the manufacturer to produce packaging materials that inhibit growth of microbes, extend product’s shelf life and reduce food waste. Tourmaline can be widely used in food packaging, healthcare products or anti-microbial coating manufacturing as an additive with an inherent capacity of keeping microbes away from the final products.
Enhanced Mechanical Strength and Durability
Tourmaline powder acts as an efficient inorganic filler which enhances the mechanical strength of the composite product. Its hard property and great durability (Mohs hardness 7.5, roughly) would naturally upgrade wear resistance and dimensional stability of composite material. Studies on tourmaline-reinforced κ-carrageenan films showed significant improvements in mechanical properties, with tensile strength reaching 8.952 MPa and elongation at break reaching 39.356%. This mechanical enhancement is particularly valuable for Hebei Hezhen's clients in the construction and furnishings industries, where durability is a primary concern.
Thus, tourmaline powder is a powerful reinforce which improves tensile strength, hardness and wear resistance. Tourmaline is an ideal raw material for manufacturers in construction and furnishing industry where mechanical properties are one of the most critical requirements for products’ quality and durability.
Far-Infrared Radiation and Thermal Performance
The unique tourmaline mineral could naturally emit far infrared rays at room temperature, which could serve multiple functions in the composite. Tourmaline/alumina composites exhibit a high infrared radiation rate of 0.89, higher than that of the individual components. Furthermore, the thermal stability of composite film including tourmaline also increases, and has lower permeability to gases.
This makes the products with tourmaline be useful in applications with certain temperature changes, such as heat-insulating materials or fire retardant coatings. As such, Hebei Hezhen, in producing a series of products ranging from heat insulating material, fire resistant coating and more—finds tourmaline powder the most favorable additive.
Conclusion
It is apparent tourmaline powder has more abilities than filler, and transforms general composite products into creative products to protect the environment as well as the human beings, not only to realize negative ion and anti-microbe to improve the physical health of the consumer, not only to improve the resistance and prolong the product’s life cycle of the strength, not only to radiate infrared light rays to bring the extra health to life, tourmaline powder is just a necessary part in the composite products of today, which would be the pleasure to get co-operation with you who are the end users or agents or dealers of the composite materials from the one who supply the good quality non-metallic mineral as a whole supplier – the company, withISO9001:2000 quality system certificate, Hebei Hezhen Industrial Co., Ltd. Wishes to have co-operation with any one who are ready for co-operation, for making the best world’s leading composite products by the top quality of tourmaline powder.
