No matter what your high performance computer needs are, there is a PC case designed to fit your needs. In that case, there are computer cases explicitly designed for that as well. Likewise, suppose you need to run multiple high end graphics cards for work that generate tons of heat. If you need to build a server that requires 15 hard drives in a RAID array, it is possible. There are computer cases today that focus on high airflow, tons of space, and plenty of IO options. Many people need to build computers to function as servers or workstations at home. Some PC cases even include options that mount components in non traditional methods so you can showcase things like your graphics card or water cooling system. You can express your style through your computer case in many different ways. For example, if you want a computer case that looks like a V8 engine, you have options. Today, you can get computer cases with tempered glass side panel windows, customizable RGB lighting, and different styles. PC Case Looks and StyleĬomputer cases no longer come in the bland color they did back in the early 2000s. With that said, you can buy a computer case for all sorts of purposes, so picking the proper computer case for you is essential. A computer case stores all of the internal components of a computer while expressing the style, tastes, and functionality of the user.

The density and crush strength of microspheres made from a particular material will depend, in part, on two structural variables, wall thickness and particle size.PC Parts options - 11 groups of items - 50 total selectionsĮlectronics options - 12 groups of items - 60 total selectionsĪccessories options - 10 groups of items - 50 total selections To some degree, there remains a correlation. Historically, crush strength for hollow glass microspheres has been directly linked to density - i.e., a glass sphere with a density of 0.125 g/cc would be rated at 250 psi (1.8 MPa), while one with a density of 0.60 g/cc would be rated at 18,000 psi (124 MPa). Therefore, on an equal weight basis, Q-Cell spheres occupy about five times more volume than the resin, which can reduce compound weight, VOC content and cost.
For example, Potters’ lightweight Q-Cell hollow glass microspheres have a density (from 0.14 to 0.20 g/cc) approximately one-fifth that of most thermosetting resins.
Typical loadings are 1 to 5 percent by weight, which can equate to 25 percent or more by volume. Densities and crush ratings, however, vary dramatically across product lines. For example, at a density of 0.6 g/cc, Sphericel hollow glass microspheres from Potters Industries (Valley Forge, Pa.), an affiliate of PQ Corp., can displace the same volume as talc at one-quarter the weight. Compared to traditional min-eral-based additives, such as calcium carbonate, gypsum, mica, silica and talc, hollow glass microspheres have much lower densities. The most obvious benefit of the hollow glass microsphere is its potential to reduce part weight, which is a function of density. The result is a rigid, hollow glass microsphere manufactured with an eye to increasing crush resistance (that is, the ability to withstand external pressure and avoid fracture of the bubbles) without sacrificing low density. Continued heating activates the blowing agent, which releases minute amounts of sulfur gas that form bubbles within the molten glass droplets. The particles are run through a high-temperature heat transfer process, during which the viscosity of the glass drops and surface tension causes the particles to form perfect spheres. Trace amounts of a sulfur-containing compound, such as sodium sulfate, are then mixed with the glass powder. Glass is initially produced at high temperatures from soda-lime-borosilicate, after which it is milled to a fine particle size. In general, a multistep process is used to produce high-temperature hollow glass microspheres. Composite manufacturers, already adept at making the most of their materials, regularly exploit these benefits - sometimes all at once. Integrated into composite parts, they provide a variety of product enhancements and process improvements - including low density, improved dimensional stability, increased impact strength, smoother surface finish, greater thermal insulation, easier machinability, faster cycle times, and cost savings. Ranging from 12 to 300 µm in diameter (by comparison, a human hair is approximately 75 µm in diameter), microspheres pack a lot of functionality into a very small package. To the naked eye, the small, hollow glass microspheres appear like fine powder. Of the many fillers now available to composites manufacturers, microspheres, also called microballoons, are the most versatile.
