Use: This product is a heavy metal removal agent, developed to protect the good environment and avoid heavy metal pollution in wastewater, even if the amount is small, it also shows a very high removal efficiency of heavy metals. Other existing heavy metal eliminators also tend to react selectively with some heavy metals, and have odor and toxicity. This product obviously overcomes these problems. Na3T is a triazine component that can precipitate almost all monovalent and divalent metals, such as copper, cadmium, mercury, silver, lead and tin. Similarly, heavy metals converted into complexes can be removed, especially for precipitation of mercury, copper, cadmium, silver, lead, nickel and tin. The significance of this product lies in a series of advantages, such as non-toxicity, odorless, convenient use, no secondary pollution, etc. Especially for heavy metal ions which can not be treated by traditional alkali neutralization method, it has a good removal effect, so it has been widely used in wastewater treatment industry containing heavy metal ions, especially in power plants with desulfurization wastewater treatment system.
Use method: TMT-NA water treatment agent is a high-tech water treatment agent. The product TMT-NA dilutes with water at 1:10-20 to form a stable liquid. It can react rapidly with various heavy metal ions (mercury, lead, copper, cadmium, nickel, manganese, zinc, chromium, etc.) in wastewater at room temperature to form water-insoluble chelates with good chemical stability, so as to achieve capture and removal. The purpose of heavy metals is to be an ideal substitute for importing similar products. Even for the coexistence of heavy metals and complex salts (such as EDTA, NH3, citric acid, etc.) in wastewater, they can play a full role, and have the characteristics of coagulation, rapid precipitation, fast dewatering, easy post-treatment, less sludge and stable non-toxic, no discoloration of water body after dosing, no secondary pollution, etc.

As a good lubricant, olefin-carbon composite nano-copper has been widely recognized by international authorities, and has been applied in some advanced projects in the United States and developed countries in Europe. Its lubricating effect and self-repairing function are not comparable to those of general lubricating oil products and organic additives, and the potential application of this technology is very wide. For example, equipment under various high-load working conditions such as automobiles, ships, aircraft, tanks and mining machinery can greatly improve the wear resistance of high-speed running parts such as precision machinery and aviation.
The olefin-carbon composite nano-copper powder lubricating oil additive developed by this technology adopts completely different ideas compared with the lubricating oil organic additive commonly used in the market at present. The nano-copper powder in the olefin-carbon composite nano-copper powder lubricant additive is adhering to the surface of friction workpiece during the oil circuit cycle, which plays a buffer role. At the same time, the nano-copper powder has better chemical stability at high temperature than the organic additive. Therefore, the possible caking and carbonization problems of lubricant at high temperature are fundamentally solved. More importantly, nano-copper powder is fine and soft, which can fill friction defects at any time and play a self-repairing role.
The functions of nano-copper lubricating oil additives are as follows:
1. Reduce the friction resistance, improve the effective power of the engine and prolong the life of the engine.
2. Eliminate the damage of initial start-up to engine and save fuel consumption.
3. Improve the efficiency of lubricating oil and ensure the power output of engine.
Nano-copper powder in olefin-carbon composite nano-copper powder lubricant additive belongs to ultrafine metal powder material.
Technical index
The experimental results show that adding 0.1% olefin-carbon composite nano-copper powder additive to lubricating oil can reduce friction coefficient by 30%, wear by 34%, fuel economy by 5% and average fuel consumption by 3%.
The technology has reached the level of industrial scale production. The average particle size of nano-copper powder can be adjusted in the range of 2-30 nm. The product repeatability between batches is good and the quality is stable.
Application scope
The application of this technology has a wide range of applications, which can greatly improve the wear resistance of high-strength and high-load equipment such as precision machinery and high-speed components such as aviation, such as automobiles, ships, aircraft, tanks and mining machinery.
When nano-copper or Nano-Bismuth alloy powders were added into lubricating oil as lubricant additives, the lubrication performance was increased by more than 10 times, and the wear of components was significantly reduced,

3. Chlorinated butyl rubber and chloroprene rubber can be vulcanized effectively by MTT, so it is very suitable to use MTT to vulcanize them together.
4. The co-vulcanization of chlorinated butyl rubber (CBR) and natural rubber (NR) compounds is of particular significance to the tire industry. Good co-vulcanization bonding is required between the lining and matrix of CBR.
Advantage:
1. Compared with sulfur curing system, MTT can obtain excellent physical properties, lower compression set and heat generation, and excellent hot air aging properties in chlorobutyl rubber.
2. The hot air aging property of rubber products vulcanized by MTT is also better than that of resin vulcanization system. The product has a low melting point and is easy to disperse. It can be mixed efficiently even in an open smelter.
3. The scorching time and vulcanization time of MTT in chlorinated butyl rubber can be delayed by MBTS or CTP or accelerated by TMTD or ZDMC. It is not appropriate to use clay alone, but it can be used with carbon black. Silica is very easy to burn, whether it is used with carbon black or with carbon black.
4. In the blend of chlorinated butyl rubber and natural rubber, MTT vulcanization can be used if the content of natural rubber is not more than 20%. When blended with chloroprene rubber, it shows excellent vulcanization characteristics and maintains the unique advantages of MTT vulcanization system.
The chlorinated butyl rubber compound containing MTT can be co-vulcanized with natural rubber, and co-vulcanization improves the adhesion of chlorinated butyl rubber/natural rubber blends.

Because it contains polysulfide bonds, it can form sulfide film with metal surface, which effectively inhibits the catalytic effect of metal ions on oil products. Therefore, T561 is a very effective lubricant additive in improving the performance of oil products. Adding 0.03-0.05% T-561 metal deactivator to the formulation of alkaline high zinc antiwear hydraulic oil, the oil can pass the hydrolysis stability test of Denison HF-2. Adding 0.4-0.5% T-561 metal deactivator to the formulation of internal combustion engine oil can increase the TFOUT induction period of oil by more than 60 minutes. In addition, T-561 metal deactivator can also be used in industrial gear oil and high-quality gasoline engine oil.

Introduction: Dimercapto-1,3,4-thiadiazole (DMTD), trimercapto-triazine (TMT) sodium salts have thiadiazole in their molecular structure. Triazine heterocycles also have highly acidic thiol groups. Thiadiazole and sodium triazine salts form conjugation effects with thiadiazole heterocycles. Therefore, thiadiazole and sodium triazine salts have certain charge attraction to some copper-bearing gold ores and can be used as flotation reagents for copper ores. Azole and triazine salts have obvious activation effect on the flotation of copper oxide minerals. A new flotation reagent TMTN-2 was prepared by flotation of copper oxide ore with DMTD alkali metal salt as activator and xanthate as collector. On this basis, a lot of popularization and application work has been carried out, and the flotation agent TMTN-2 for copper oxide ore has been produced in batches for use in mines. DMTD salts and triazine salts have been successfully used in the flotation production of copper oxide ores, so that the concentrator can obtain better benefits.
