Bromine is an important flame-retardant element in many products and has been widely used in the world. These products include household appliances, paints, furniture and flame retardants, but the bromine element has been proved by a large number of scientific experiments and is a modern social water. One of the "primaries" of toxic pollution of resources, soil and atmosphere is mainly hormones, genetics and neurotoxins. The European Union has established a directive requiring the ban on the use of bromine in products for a limited period. “Relentless†actively researches and develops fire-extinguishing flame retardant technology that replaces the current bromine elemental composition, and is fully funded and supported by the EU’s Seventh R&D Framework Program (FP7), led by scientists from the IES Institute of Technology, the European Union. The top priority of the European ENFIRO R&D team with the participation of multinational scientists and technicians.
The European Commission has identified three major goals that must be ensured for the alternative technology of bromine: 1) economic feasibility in manufacturing and application; 2) environmental friendliness and safety and reliability; 3) the life cycle of the product should be recycled as much as possible .
Innovative flame retardant technology based on metal, phosphorus or nanoclay developed by the European Commission, compared with current brominated flame retardant technology, its economical performance, flame retardant safety and reliability, and economic society Environmental benefits, completely replace the bromine flame retardant as a "latera" new generation of flame-retardant product technology. Its toxicity studies such as flame retardancy, flammability, toxicity, spread of fire and smoke volume, and no polymer/halogen values ​​are much lower than brominated flame retardants.
Innovative flame retardant technology not only makes important contributions to fire safety, but can be further promoted in the fields of printed circuit boards, polymers and textile coatings.
Hejian Deris are Both manufacturer and distributor, specialize on Core Bit include two type both PDC core bit and Impregnated Diamond Core Bit
PDC Diamond Core Bit Use high-quality steel to make the base material of PDC Bit, the surface of the blade weld high-performance wear-resistant materials, the use of computer software for the overall design of Asymmetric spiral bevel blade, lng parabolic cone structure.
Suitable for low compressive strength homogeneous laminated formations, such as clay, marl, lignite, sandstone and so on.
impregnated diamond bit have the widest range if application. They are the most commonly useful bits from medium to super hard formation in the mineral exploration industry. THE Hardness and abrasive of the rock formation are the key factors to determine the diamond specifications, concentration and matrix hardness.
Toothed bits can get higher
drilling efficiency when it is drilling at dense or abrasive stratum with lower
drilling speed and pressure. It want especially effective arc pal formation,
using toothed bits can get better water flowing and drilling footage effect.
Nowadays, Impregnated diamond bits have been widely used in wire-line drilling
