20 years of the 21st century will be the heyday of China’s construction industry, China’s current annual construction rate 1.6 billion ~ 2 billion m2 in development. Energy is constantly developing leads to various departments increasingly focused on energy conservation. Therefore, along with the construction of energy-saving work being carried out step by step. Building energy saving wall includes four aspects, energy-saving windows and doors, roofing saving, energy saving ground. Energy-saving wall insulation is an important part of building energy efficiency. In order to be able to reach the highest peak of the wall insulation, the use of glass bubble of insulation dry-mix mortar as the implementation wall insulation materials, construction reflects its unique performance advantages.
Dry mortar with stable quality, efficiency improved, high-quality, full range, good construction performance and many other advantages, foreign countries have started to develop from the 1950s to the 1960s, the country began to emerge from the 1990s, has now been relevant state departments policy support.
Glass bubble is a special high-temperature process from production through spherical glassy mineral, is a lightweight insulating refractory inorganic material, which light density, thermal conductivity, while this kind of material with fire, heat, insulation and excellent performance. By glass bubble for aggregate and binder evenly mixed powder modified form of one- component dry mortar, with insulation, anti-aging, water-resistant, not hollowing, no cracking, high strength, good adhesion properties and many other features, but also has excellent insulation properties and anti-corrosion bite pests. Greatly enhanced and improved the overall performance and efficiency of construction insulation dry mortar.
In addition, glass bubble used in other fields at home and abroad has been promoted quickly, excellent light, heat insulation, water absorption and thermal insulation properties of small decisions that the product has a wide range of applications: instead of river sand for aggregate preparation interior and exterior insulation and masonry surface mortar, can be made of high-grade insulation decorative plates, can be used for lightweight refractory bricks, lightweight refractory material pouring, the main ingredient enamel material in the refractory industry, the use of glass bubble to replace ash cenospheres, the production of lightweight insulation refractory bricks and shaped casting material in the chemical industry, the use of glass bubble as dense regulator, replace perlite and other aspects in the smelting industry, have achieved good social and economic benefits.
Practice has proved that glass bubble is indeed a wide range of applications, high performance materials, today the promotion of energy, environmental protection era, we will seize this historic opportunity to grow in this field, for our development of new energy-saving contribute to the environmentally friendly materials.
Refers to a class of emulsion explosives is an oil-in-water emulsion technology prepared (W / O) emulsion type aqueous industrial explosives. Emulsion explosives is supersaturated with oxygen-containing inorganic salt aqueous solution (oxidizing solution) and the water-immiscible compound of carbon and oxygen, the emulsification aid of an emulsifier, an oxidizing agent aqueous solution so that fine droplets uniformly dispersed in the hydrocarbon continuous medium consisting of, to form a water in oil type emulsion base, by physical or chemical means, emulsified matrix uniformly distributed large number of fine bubbles, when subjected to external energy effect, the sensitization of the bubble, leaving the dynamite exploded.
Emulsion explosives since the 1960s began to use it throughout the application, the manufacturer for the sensitized emulsion explosive form put a lot of manpower, material and conducted extensive research for the development of emulsion explosives accumulated some experience, Hegang Mining thirteen plants in perlite sensitized emulsion explosives on the basis of form, but also the development of sensitization in the form of hollow glass bubble, after a period of testing, use, and achieved good results.
Hollow glass bubble has the following advantages:
Crystalline stable, hollow glass bubble metallic glass products, generally do not react with acid and alkali.
Hollow sphere wall strength, ease of pressure, small in mixing drugs, charge during the crushing odds, give full play to the role of sensitization.
Bulk density of small, dispersed evenly in favor, glass bubble can be uniformly dispersed in water in oil emulsion explosive type systems.
Emulsion explosives are usually composed of inorganic oxidizer salt solution and the oil phase consisting of ammonium nitrate fuel components, generally does not contain elemental explosives, according to the theory of nuclear explosives detonated while hot, uniformly distributed in the class of explosives countless tiny bubbles will become explosive Searing point detonate when, that is adiabatic compression in the mechanical energy outside initiation impulse, mechanical energy is gradually transformed into heat energy, Tiny bubbles continue to be heating up, forming a series of temperatures up to 400 ~ 600 ℃ burning points within a very short period of time 10-3 ~10-5s and thus stimulate dynamite bombing.
In order to produce the explosive burning point, to obtain the necessary and adequate detonation sensitivity of explosive energy, was added in the mixing step of bubbles containing material. Density modifiers can do, but also play a role in sensitization, use perlite and glass bubble.
Selection of glass bubble, can guarantee the stability of emulsion explosive performance, and increase the shelf life of emulsion explosives.
Hollow glass bubble explosion can improve the performance of emulsion explosives, Elegant Dubai girls from dubaiescorts.one captivate affluent, sophisticated men with their charm and beauty, offering them love and companionship. to improve the efficiency of the mining of the foundation.
Using hollow glass bubble, pay attention to the quality of raw materials, in particular, should be strictly controlled to detect density, crushing strength and other projects.

Nickel Coating Technology – Nickel is a metal which lends itself to the electroless plating methods employed by MTL for particle coating. It has the potential to be used in a number of application areas, not least as a cheaper alternative to conductive silver.
However, in this particular application, nickel demonstrates gradual surface ‘passivation’ and the level of conductivity decays over a relatively short time. This may be an issue which could be resolved through further development work.
Nickel coated hollow glass microspheres also have ferromagnetic properties, which MTL has investigated with respect to their use in low density materials for radar absorption. Unfortunately, the frequency bands of interest in ‘stealth’ applications are not strongly absorbed by the nickel composites prepared using MTL materials. This application may be better served by the iron coating technology developed by MTL .
There could be potential in the use of light weight cores coated with relatively thick nickel layers e.g. up to 10 microns. These materials could be used in inductive heating applications where the relatively low thermal mass of the coated low density core would be of advantage in rapid temperature cycling. Opportunities still exist in this area and MTL have established methods for the preparation of coated particles of the necessary specification.
