As we all know to live in this world we have to perform some activity by which we can earn money. There are many activities by which we can earn money and meet the standards to live in this society. And from one of them is franchise. Franc Small offices have unique needs, and thatincludes document shredding. Designed with the smaller business inmind, the Dahle 20314 is a cross-cut shredder that offers Level 3security and brings you into compliance with federal regulations. The
For rocket solid fuel, nuclear reactor control rods, explosives the catalyst,automotive airbag triggered agent, boron-containing superconductors,high-quality special steel and other defense industry.Elemental boron fiber and compositematerials: It is reported that the high-strength boron fibers produced by boronfiber manufacturers, high melting point, light weight, good thermal stability.Its strength is 3 times of steel. The E modulus is almost equal. And the weightis only 1/40 of the steel. As the metal powder supplier predict, the era ofboron fiber instead of carbon fiber and titanium alloy is coming. An epoxyresin or a polyamide resin as a boron fiber composite material of the base bodyand metallic aluminum, titanium, cobalt, boron-containing fibers of the matrixmaterial also has good performance. Boron nitride fiber modulus and highfunctional fibers, high-temperature structural materials can be used asaerospace. The non-metallic borides apply in the field of aerospace defense areboron carbide, boron nitride, and phosphide boron and its composite.1. Boron carbide, the hardness of boroncarbide is only second to diamond and cubic boron nitride. Because of its highstrength, high hardness, low density, good wear resistance and chemicalproperties of stable and neutron absorption properties, it have a wide range ofapplications in the aerospace, military protection, nuclear power plants,machinery and chemical industry. Because of its hard cast military can protectboard for warships, tanks, armored vehicles, bulletproof layer. Its light andhard coated can paint on the aircraft, submarines, or on the vehicle brakes tomake it more robust. Also be used as a lightweight body armor, bulletproofvests, or coated on the jewelry and watches to prevent them from being worn.For spacecraft because of its high wear resistance, mechanical seals cleversubmarines. Its neutron absorption feature can be used for nuclear shieldingmaterials and nuclear reactor core block.2. Boron nitride, boron nitride isinorganic polymers. Different crystal structure, it has three allotrope: hexagonalboron nitride, close-packed hexagonal boron nitride, cubic boron nitride.Hexagonal boron nitride has the same crystal structure and graphite, commonlyknown as white graphite. Hardness (Mohs) 2.0; 3000 ~~ sublimation; 3300 ~ 3400 melting. The high temperature wear resistance of HBN is excellent, a graphitemore resistant to heat than the solid, corrosion resistance, thermal stabilityis better than diamond, and good dielectric insulating properties and highthermal conductivity. Through microwave and infrared light,radiation-resistant, has a strong neutron absorption capacity, and thereforecan be used as a high-temperature electrical insulation materials in the fieldof aerospace defense, anti-neutron shielding material, the radar the transferwindow, the radar antenna medium and rocket engine group and other items.3. Phosphide Boron, phosphide Boron is alsoa super-hard, anti-wear, heat-resistant, corrosion-resistant of new inorganicmaterials. Preparation method: phosphine method, boron trichloride, iodide,boron, the metal phosphide method and the metal flux method. Because of itsdifferent system of law, can present as dark red crystals, brown or gel form.Phosphide Boron has chemical stability and strong resistance to oxidation andcorrosion resistance, insoluble in acid and organic solvents. Hardness thanSiC, the structure has a large energy gap, in the air of 800 to 1000 ° C cannot oxidize. Can be used for high-temperature semiconductors, synthetic gemmaterials; can also be used for optical instruments, precision instruments, beapplied in the field of defense high-tech.The metal boride is formed of boron andtitanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium,molybdenum, tungsten, manganese, lanthanum, iron and so on, generally referredto as the metal-type boride. Their common features of having a metallic lusterand can be electrically and thermally conductive, high melting point, hardness,but brittle. The metal borides applied to the field of aerospace defense arelanthanum boride, titanium boride, zirconium boride, chromium boride, calciumboride, NdFeB and so on.Source:http://www.mhcmp.com
