The main characteristics of nano-titanium nitride ultrafine titanium nitride powder prepared through a special process, high purity, small particle size distribution, large surface area, surface activity, rich nitrogen (> 35%), high temperature, oxidation resistance, high hardness, excellent absorption of infrared performance (80%), UV shield is greater than 85% can be applied to the top of the insulation coatings and automotive ceramic membrane, heat insulation and temperature effects. The material has good electrical conductivity, can be used as a molten salt electrolysis electrodes and electrical contacts and other conductive materials, for toughened ceramics as well as high temperature structural ceramics, the effect is very good.
Applications
Plastic applied to the packaging materials in a nano-titanium nitride barrier solve the yellowing characteristics of the application: the composite of nano-TiN barrier technology, Nano-TiN and composite resin to form a composite material, these nanoparticles were able to block the molecular gap, the gas diffusion is difficult to penetrate, thereby enhancing the barrier properties of the resin, plastic. Added the number of nano-materials is very small, this material can be applied directly on the various existing process, and do not need to update equipment. Add the proportion of one ten thousandth of Du can guarantee transparent, clear polyester appearance, barrier properties increased by more than 8 times, due to the high nitrogen content of titanium nitride, titanium nitride dispersed slurry is light blue without adding any color of spices, can obscure the polyester itself yellowing characteristics (permanent yellowing), reduce customer to add a large number of coloring agents, to reduce costs;
2 PET plastic Applications: a small amount of nano-titanium nitride powder used in engineering thermoplastics such as PET, PA, etc., can be used as a crystallization nucleating agent to use nano-titanium nitride deployment into the nano-dispersed with ethylene glycol slurry, better dispersion of nano-titanium nitride and PET engineering plastics by polymerization of the way, can greatly accelerate the crystallization rate of PET plastic, making it simple molding, to expand the scope of application of the PET engineering plastics. At the same time a large number of nano-titanium nitride particle dispersion and PET has been significantly improved wear resistance, impact resistance of the PET engineering plastics due to nanometer effects;
3 high thermal emissivity coating applications: the key material of high thermal emissivity coating material of high nitrogen content of nano-TiN powder as used in high temperature, add the component to the development of coating materials with coatings prepared by plasma spraying The detected rate of heat radiation performance is greatly improved, the product is mainly used in high temperature furnace energy-saving, military;
4 the development of lead-free solder materials, incorporation of trace titanium nitride nanopowder tin, silver, copper, zinc alloy, the melting temperature lower 200 ° C, generate the alloy is more uniform, reducing the oxide solid solution temperature of 30 ° C, can achieve the original tin-lead solder temperature, if we can further improve the infiltration, the largest application of the difficulty of solving the existing lead-free solder;
5 Preparation of green electronic materials can not use chromium and other harmful elements as lead, cadmium, high-priced, high-temperature bonding of glass phase lead-free, cadmium ceramic media, packaging and glass frit problem is the solid-phase synthesis of high temperature, high softening point, high temperature into a porcelain be able to join the micro titanium nitride nanopowder make solid-phase reaction temperature lower 200 ° C, even if the lower 50 ℃, be able to use the existing process equipment, is also a big breakthrough. Titanium dioxide and its solid solution is the composition of electronic materials, nano-form of the introduction of mutations may be beneficial to bring the performance;
Containing bromine (Br) 6-pollution laws limit the use of benzene polymers, to the electronic flame retardant, plastic pieces of shell skeleton pose difficulties in engineering plastics to add a small amount of silicon nitride, silicon carbide, titanium nitride, carbide titanium nanopowder, not only to increase the mechanical strength, wear, heat and other properties, such as replacing containing bromine flame retardant material properties, the application of organic polymers is a major breakthrough;
Other fields of application: in the nanocomposite hard cutting tools, carbide, high temperature ceramic conductive material, heat resistant materials, dispersion strengthened materials, can be applied to the electrode catalyst for fuel cells, anti-static material and conductive ceramic .
