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 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
It wasonly after the 1940s that titanium was fully understood and utilized by humanbeings. The special strength of pure titanium and titanium alloys isrespectively 2.3 times and 3.8 times of low carbon steel, 1.8 times and 3 timesof stainless steel. So titanium is a lightweight, high-strength metalstructural material, and was widely used in the aerospace, marine, chemical,pharmaceutical and other fields. This characteristic of titanium is also widelyused in general industry and everyday items, such as high-end bicycles, golfclubs, upscale eyeglass frames and so on, also known as "all-roundmetal" or "third metal". Asearly as 1908, Norway andthe United Statesbegan to produce titanium dioxide by the sulfuric acid method. To 1948, the United Stateshas begun to produce tons of titanium sponge, which is also the beginning ofthe titanium industrial production. However, due to the important value of titanium powder in the military, aviation and other fields, the global technologyblockade is extremely tight, Chinadevelops titanium industry can only through the approach of independentinnovation or purchased from a third party, while purchase from third party isnot only cost too much, but also the purchased technology will be greatlyreduced. Titanium'smemory function refers to one kind of titanium alloy has the ability toremember their shape. If use this alloy to manufacture car shell, after hittingdeflated, just pouring with boiling water, it can be intactly restored. Thisamazing features of titanium makes it become irreplaceable metal materials inspecial projects, aerospace, medical. In addition, one kind of titanium alloyin close to absolute zero will be showing zero resistance, the wires made from it can passany large current and without heating, without energy consumption, it is thebest material for transmission power. Titaniumis not only resisting high temperature, low temperature performance is alsogood. Titanium alloy can still maintain good mechanical properties at about 500,under the low temperature of -253to -196 can maintain good ductility andtoughness, particularly suited to the requirements of the space environment onthe materials, which is also known as "space metal". Titanium alsohas the properties of non-magnetic, non-toxic, in a large magnetic field willnot be magnetized, ships shell which made of titanium can prevent magneticmines explode. Titanium is non-toxic and has good blood compatibility withhuman tissue, Bone and pacemaker made of titanium not only have a strong affinity with the human bodyonly, but also not subject to a strong magnetic field environment, also called"Biology metal". Titanium'soxide - titanium dioxide, is a kind of white powder, the best white pigment,commonly known as titanium dioxide. Metal powder supplier said that former people mining titanium ore are mainly to obtaintitanium dioxide. Titanium dioxide has strong adhesive power, uneasy to causechemical change and always keep white. What especially valuable is thattitanium dioxide without toxicity. Its melting point is high, being used tomanufacture fire-resistant glass, glaze, enamel, clay and other heat resistingexperiments utensils, etc. Titaniumdioxide is the whitest things in the world, 1g of titanium dioxide can be painted more than 450cm2 area to snow-white. Itis 5 times whiter than the commonly used white pigment - lithopone, so that itis the best pigment to modulate white paint. In the world, there are tens oftons titanium dioxide used as pigments every year. Titanium dioxide added in apaper can make the paper white and opaque, the effect is 10 times larger thanthe other substances. Therefore, banknote paper and art paper should be plustitanium dioxide. Furthermore, in order to lighten the color of the plastic,make the rayon sheen to soften, sometimes it also needs to add titaniumdioxide. In the rubber industry, titanium dioxide is also used as white rubberfiller. ArticleSource:http://www.mhcmp.com
