1)  Properties

Detonation-synthesized polycrystalline diamond powder

The structure resembles the rare natural polycrystalline black diamond, metallic-grey, superior toughness, self-sharpening.

The lapping and polishing efficiency of the detonation-synthesized polycrystalline diamond micro-powder is 2 to 4 times better compared with that of the mono-crystalline diamond that is naturally occurred or synthesized via the static pressure method, Silicon Nitride, Corundum, and other abrasive materials.

polycrystalline diamond micro-powder allows the manufacturing of the smoothest surface possible:

1.  When using diamond micro powderof size 2-4micron to the polishing surface, Ra(roughness)<1.6nm
2.  When using polycrystalline diamond micro-powder of size 0-0.5micron to the polishing surface, Ra(roughness)<1.3-1.4nm
3.  When using polycrystalline diamond micro-powder of size 0-0.125micron to the polishing surface, Ra(roughness)<0.1nm

polycrystalline diamond can maintain its dull mono-crystalline structure by releasing the outer layer, hence will produce the most scratch free surface possible.

When applied to the surface of a workpiece (for example, the inner surface of a cylinder in an engine) via chemical plating method, the wearability of the surface is superior to that of a surface treated with any other materials.

Via after-sinter technique, polycrystalline diamond micro-powder can be turned into polycrystalline diamond particles of a large size that are highly valuable in a variety of industries.

Pesticides with trichlorethylene as the solvent include trichlorfon and dimethoate which are popular pesticides in China. The application of trichloroethylene being used as the extractant agent for purification of the pharmaceutical intermediates-methoxy-phthalic acid has also increased largely in recent years.Application of trichlorethylene in other areas of consumption includes expanding agent, coating of unsaturated resin, which accounts for 5%; application of PCE and refrigeration agents accounts about 10%.

CAS NO.:79-01-6

Trichloroethylene (TCE) is hard to dissolve in water but soluble in ethanol, ether and so on. TCE is a flammable liquid that can cause fire and explosion when exposed to open flame or high heat.

Hazardous characteristics: In case of fire and high heat energy, TCE is likely to explode. It can react with strong oxidants. When exposed to ultraviolet light or decomposed during combustion or heating, toxic phosgene and corrosive hydrochloric acid fumes are generated.

Combustion (decomposition) products: carbon monoxide, carbon dioxide, hydrogen chloride, and phosgene.

TCE was used as an analgesic and a metal degreaser. It can also be used as an extracting agent, bactericide and refrigerant, and a clothing dry cleaner. Prolonged exposure can cause trigeminal nerve palsy and other illnesses. As an excellent solvent, it is used as a metal surface treatment agent, a cleaning agent before plating and painting, and a metal degreaser and extracting agent of fats, oils and paraffin. It is applied in the organic synthesis and pesticide production. TCE is used in the production of tetrachloroethylene as an anthelmintic and hexachloroethane as an anthelmintic for veterinary use. It is utilized in chemical cleaning and industrial degreasing, and as chemical raw materials.

 Invasion routes: by inhalation, ingestion, and percutaneous absorption.

 Respiratory protection: You should wears self-priming filter gas masks (half masks) when you may be exposed to TCE vapors. You should rescue oxygen breathing apparatus in emergency rescue or evacuation.

 Eye protection: Wear chemical safety glasses.

 Physical protection: Wear anti-poison infiltration workwear.

 Hand protection: Wear protective gloves.

 Others: No smoking, eating and drinking on job sites. After completing work, get bathed and have clothes changed. Store clothes that are contaminated with TCE alone as spare clothes. Pay attention to personal hygiene.

Exothermic welding, also called hot melt welding, fire-clay welding, thermite welding and explosion welding, is a high-heat principle that utilizes the redox reaction between metals, the operation of which is simple, easy to learn, safe and efficient, and it has significant results in the production of high quality permanent welded joints between homogeneous metals and metals of different materials and is now well known to the public, becoming more popular in more and more architectural designs, and widely required to replace the connection method using conventional metal fixtures.

Exothermic welding products require high-quality graphite to form a cavity mold with a certain shape, such as line style (butt), T-joint (three-way), cross-type joint (four-way) and so on. The mold can be used multiple times, effectively saving costs.

Exothermic Welding Advantanges:

1. Good electrical conductivity: the current-carrying capacity of the welded joint surface is almost the same as that of the metal conductor, and the electrical conductivity is strong.

Experiments have shown that the the change rate of DC resistance before and after welding is close to zero, which is incomparable with any traditional connection mode.

2. Long and durable life: due to the high temperature fusion between the metal conductors during exothermic welding, an integrated permanent joint is formed, which is very strong and difficult to break and damage.
3. Strong corrosion resistance: the material of the welded point is mainly copper, and the corrosion resistance is almost the same as that of copper.
4. The operation is convenient and simple with no need for professionals but can be performed only after pepole are simply trained by professionals.
5. The requirement for operating environment is low, and no external power source or heat source is required for welding.

Operation flow of hot-melt welding

1. First, the mold and the copper clad steel groundingshould be cleaned, and then the welded conductor should be fixed at the center of the mold cavity.
2. Close the mold and steadily place a metal protective gasket on the bottom of the mold furnace.
3. Pour in the exothermic welding flux, and evenly spread the starting powder on the surface of the flux and place it in an environmentally friendly starting powder.
4. Cover the mold, expose a part of the pyrophoric wrap at the mold opening, and then ignite the starting powder with an igniter.
5. After the hot-melt flux is ignited, a high temperature reaction occurs in the mold.
6. After the reaction is completed and cooled, the mold is opened and the welded conductor has been permanently connected.

Welding For Grounding Precautions Flammable and explosive articles shall not be placed within 2 meters of the site during construction operation. Unrelated personnel shall not stay and operators must wear heat insulation gloves and related protective equipment.
