The production and main use of silicon metal powder Business Articles | November 8 T.J. Green Color Rush Jersey , 2012
Metal silicon is a brittle material, sieve residue in the grinding process can not be well controlled, serious over-grinding phenomenon caused by silica fume waste, high production costs, product size standards, not only makes the product yield not competitive.?


Equipment of grinding silica fume has extrusion mill, disc mill, raymond mill Marlon Mack Color Rush Jersey , jaw crusher, etc. These devices not only to high energy consumption and low efficiency. Makes the production of silica fume stagnant. But the column mill is a new type of vertical mill. Use medium speed pulsating, continuous repeated low-pressure roll grinding principle and scientific structure design, so it has both high pressure roller press roller mill performance, and with no defects. Reduction gear device so that the spindle is rotated when the motor driven, mounted on the spindle bearing and of several rollers mounted on the carriage to rotate in the ring tapered liner adjustable gap between the rollers and the inner liner, when the material from the inlet into the mill, due to the force of gravity and upper pusher role Tarell Basham Color Rush Jersey , the material uniformly from top to bottom by lining four weeks, and roller repeated rolling into powder, the last from the mill lower part of the automatic nesting. As the roller wheel relative to the revolution and rotation of the liner for the rule, and can vary with the size of the material layer thickness and the material particles flexible fluctuations, and the rollers and the liner no contact, thus avoiding both between subject to reasonable impact on energy consumption and wear, the materials repeatedly rolling and grinding here, plus grinding roller and the liner material is selected to wear better wear-resistant alloy multi-element steel Quincy Wilson Color Rush Jersey , to minimize the extent of the contamination of material processing machinery iron powder processing.


Silicon metal powder, also known as industrial silicon powder, is silver gray or dark gray powder, with metal luster. Its high melting point, good heat resistance, high resistivity, is highly resistant to oxidation, known as the "Industrial MSG" indispensable basic raw material for many high-tech industries. Silicon large for smelting ferrosilicon alloy as a reducing agent for the iron and steel industry as an alloying element in a variety of metal smelting. Good silicon or aluminum alloy Malik Hooker Color Rush Jersey , the vast majority of cast aluminum alloy containing silicon. Silicon is the raw material of ultra-pure silicon electronics industry, ultrapure semiconductor silicon electronic devices do have advantages of small size, light weight, good reliability and long life. Silicon single crystal doped with specific trace impurities made of high-power transistors, rectifiers and solar cells is better than germanium crystal .


The main uses of silicon metal powder: silicon metal powder is widely used in refractories, powder metallurgy industry, in order to improve the high temperature, abrasion and oxidation resistance. Its products are widely used in steel-making furnaces Tyquan Lewis Color Rush Jersey , kilns, kiln furniture. In organic silicon chemical industry, metal powder is the basic raw material of the silicone polymer synthesis, such as for the production of silicon monomers, silicone oil, silicone rubber, preservatives, so as to improve the heat resistance Kemoko Turay Color Rush Jersey , electrical insulation properties, corrosion resistance, waterproofing other characteristics.Industrial silicon powder made by pulling monocrystalline silicon processed is widely used in high-tech fields, integrated circuits, electronic components essential raw materials. The metallurgical foundry industry, silicon metal powder as a non-iron-based alloy additives, silicon steel alloy agent, and thus to improve the steel hardenability. Industrial silicon powder can also be applied to some metal reducing agent for the new ceramic alloy. Silicon metal powder is mainly used for the basic raw material of silicone polymer materials (such as silicon Braden Smith Color Rush Jersey , trichlorosilane, silicon, etc.).

Emergency Room Events


A female came to the emergency room with severe stomach pain. She told the nurse that she had felt bad for some time, and had recently lost weight Darius Leonard Color Rush Jersey , yet not decreased her caloric intake. The patient told her nurse she had been concerned for some time, but was embarrassed, as her bowel habits had changed as well, with what she described as a stringy mucus substance. The nurse assured her there was nothing to be embarrassed of, and the testing proceeded. Within an hour the attending physician informed the patient that she had a tapeworm, and that it was quite long. Medication was given, and the nurse monitored her until the worm passed. The nurse was instructed to measure the parasite. She had to have assistance to do so, this tape worm was 16-12 feet long. The patient was fine.

e all was fine.


Foreign Accent Syndrome is a very strange condition that makes no sense at all, and really cannot be explained. With this condition, a patient may.
