Why the skull repair with titanium wire mesh?

Titanium has the following several reasons: 1 titanium has a “pro” ‘of biological. In the human body, can resist the corrosive and non-toxic secretions, of any sterilization method. It is widely used for medical devices, artificial hip joint, knee joint, shoulder joint, stress, skull, active valve of the heart, skeletal fixation clamp. When the new muscle fiber ring wrapped in these “titanium bone”, they began to titanium bone maintains the normal activities of the human body. Heat resistance of 2 titanium 3 titanium is better in the body stable performance, not easy to deformation, only in the pressure big obvious place, can obviously feel discomfort. Titanium compared with other metals, has the following advantages: 1 tensile strength can reach 100 ~ 140kgf/mm2, but the density is only 60% of steel. 2 good corrosion resistance, in the atmosphere of titanium surface to form a uniform layer of dense oxide film, have the ability to resist various medium erosion. Usually titanium has good corrosion resistance in oxidizing and neutral medium, corrosion resistance in seawater, wet chlorine and chloride solution is more excellent. But in the reducing medium, such as hydrochloric acid solution, poor corrosion resistance of titanium. 3 low modulus of elasticity, small thermal conductivity, non ferromagnetic. The network without plate, strip, fast, as upstairs said, the skull is in an arc structure, network softness is relatively high, and combined with the bone between the to be intimate. Can quickly bent into suitable for the skull surface anatomy of the other, which is suitable for craniofacial plastic parts of the structure shape cut into the appropriate size, rigidity and toughness to rational balance meet the need of repair and reconstruction of craniofacial surgery www.aphcmetalmesh.com

Stainless steel wire mesh are applied to what the industry scope

Stainless steel wire mesh is a 304 304L 316 316L as raw material woven into a deep processing of wire mesh products by using high quality stainless steel wire SUS302. For stainless steel wire mesh weaving: plain weave, twill, method of dense weaving. Because the stainless steel material to its own characteristics, the processing of stainless steel wire with high strength, long service life, accurate, uniform mesh structure, not curly, easy to use, the screen thickness uniformity, antistatic, acid and alkali resistance, corrosion resistance, products with acid and alkali resistance, temperature resistance, wear resistance and other properties, therefore, in recent years, stainless steel wire mesh is widely used in coal mine, petroleum, chemical, food, medicine, machinery manufacturing industries as the mesh.

Use stainless steel mesh can be used for flood control, transportation, water conservancy construction or safety net, network or network. Because of the use of stainless steel as the metal material, which has the characteristics of corrosion resistance, high strength, soft, good performance. The stainless steel mesh can be divided into: stainless steel mesh, stainless steel dense net (mat shape net) ultra wide network (1.2-3.5 meters 5-8 meters) wide, large shaped net, special specifications can be added according to the needs of the user custom processing, another company also can be made of stainless steel tableware, stainless steel products such as coal washing net.

Use: stainless steel wire mesh is mainly used for acid, alkali conditions screening and filtering. Mainly used as the oil industry for net mud, chemical fiber industry as screen mesh, plating industry as pickling network to use. I plant the production of stainless steel net as the building safety net is not easy to be hard cuts, can adapt to the harsh outdoor environment, can be repeatedly used, only one input can be repeatedly used, reduces the cost. The stainless steel mesh used in engineering water conservancy, can effectively prevent the bank water scour caused the collapse, ensuring full Reservoir River safety. If it is found that the stainless steel welded wire mesh with holes, causes of surface porosity is due to stainless steel containing C, S, Si was easy to porosity. The solution or replacement of stainless steel material, or is the use of low hydrogen welding slag. Welding position is not clean can easily cause stomatal. Therefore, welding parts require cleanup before welding, rust and other dirt. Low hydrogen welding rod when using more rigorous requirements. Welding current is too large. The electrode of drug skin turned red, but also prone to stomatal. Therefore requires a suitable welding specification. The welding current maximum to electrode root without red is appropriate. Low hydrogen electrode is easy to absorb moisture, so before use should be baked at a temperature of 350 ℃ for 1 hours. Or it is easy to appear the blowhole. Welding wave joint porosity: Using low hydrogen electrodes are often prone to surface and the internal pores in the weld joint, and its solution: welding wave joint, should be in the direction of the weld from crater 9 ~ 10mm starting arc, arc burning, first as a reverse operation rod back to the crater position, fully the melting and forward, or at the weld arc can avoid this type of stomata.

The difference between the screen and Grill

The sieve is suspended solids and impurities removal of thick, in order to protect the follow-up treatment facilities to a preprocessing method for the normal operation of the. Member filter consists of parallel rods, bars, metal silk fabric, grid or perforated plate. Which is composed of parallel holding and strip called Ge Shan, a metal fabric, grid or perforated plate is called a screen. The removal of the material is called sieve. The Ge Shan removal are those may clog pump and pipeline closed door coarse suspended matter. And the screen is removed in small fiber anger floating state is difficult to remove by GE shan.

According to the different methods of cleaning, Ge Shan and screen can be design for adult workers slag and mechanical slag removing two. Artificial slag lattice is only applicable to dirt access less with little quantity or interception of occasions, when a large amount of dirt, the general should adopt mechanical slag, in order to reduce the amount of manual labor. Ge Shan is one of the most simple filtration equipment, suspended substance used to intercept sewage gross and floats. The shape and the size of Ge Shan is decided by its use.

Removal of a screen, and effects of primary sedimentation pool. At present, there are two main screen used in wastewater treatment or short fiber recycling, vibrating screen and hydraulic screen. As shown in Figure 2-4 structure of vibrating screen. The sewage from the channel flow of the vibration sieve, separation of water and suspended matter here, and the use of mechanical vibration, vibration screen will show entrapped inclined plane on the fiber and other impurities discharge to the fixed screen, further filter attached to the fiber drop.

As shown in Figure 2-5 structure hydraulic screen. Moving the screen was truncated conical, central axis in a horizontal state, the cone is inclined direction. The small end of the cone into the water, in the water flow from end to end in the flow process, fibrous contaminants being screen cut left, water from the stream of small hole screen people collecting device. Because the entire screen presents a cone, pollutants are trapped and the inclined plane of the screen into a fixed along the screen, in order to further filter the water droplets.

The screen relies on the inlet flow as rotating power, so in the water inlet end hydraulic screen generally do not set the screen, and impervious material wall, when necessary, can be arranged on the wall surface water guide vane is fixed, but should pay attention to, can not be too much exercise sieve weight. In addition to the waste water inlet pipe location and outlet diameter is also to be appropriate, to ensure that the water has a certain velocity into the water guide blade, rotary movement screen using water impact force and gravity.

Design of hydraulic screen generally inlet pipe in the water to maintain a certain pressure, the size and the size of the screen pressure and properties of wastewater. Disposal of pollutants, the screen grid method of entrapped: landfill, incineration (820 ℃) and compost. Can also be grid slag crushing and then return to the wastewater, as the settleable solids into the primary sedimentation tank. Mill is the use of high-speed rotating knife gate slag crushing. Mill has a vertical cylinder grid, mill should be set up in the sand pool, so as to avoid large inorganic particles damage the mill. In addition, in rags and fabric in crushing before removal.www.aphcmetalmesh.com

The difference between cold and hot rolling Perforated Metal Mesh

Cold rolled plate Perforated Metal Mesh and hot rolled plate punching net is made of two kinds of steel rolling technology, as the name suggests, is in cold rolling steel at normal temperature are rolled, the steel hardness. Rolling hot rolling is steel under high temperature.

1 hot rolled paper

With the continuous casting slab or slab as raw material, after reheating furnace heating, descaling entered the roughing mill high pressure water, roughing cut is expected by the head, tail, and then enter the finishing mill, the implementation of the computer controlled rolling, finally after rolling through the laminar cooling (computer controlled cooling rate) and coiler, become straight hair volume. Hair straightener roll head, tail often forms a tongue shape and fishtail, thickness, width of poor accuracy, edge has wavy, folding, tower and other defects. The volume weight heavier, steel coil diameter is 760mm. (general pipe industry like use. ) the straight through cutting head, tail cutting, trimming and multi pass straightening, formation of finishing line processing, cut into boards or heavy volume, namely: hot rolled steel plate, become flat hot rolled steel coil, slitting with other products. Hot finishing rolling by pickling descaling and greased become namely after pickling hot-rolled plate roll. The product has a tendency to partial substitution of cold rolled sheet, moderate price, by the vast numbers of users.

The 2 cold rolled plate

Hot rolled steel coil as raw material, acid pickling descaling after cold rolling, the finished rolling hard volumes, due to continuous cold deformation caused by the cold hardening the volume rolling hard strength, hardness, toughness and plastic index rise decline, so stamping performance will deteriorate, can only be used for simple deformation of parts. Rolling hard volumes can be used as a hot galvanizing plant raw material, because the hot dip galvanizing line are provided with the annealing line. Rolling hard volumes weight in general 6~13.5 tons, steel coil diameter is 610mm.

General cold rolling plate, volume shall be continuous annealing (CAPL unit) furnace annealing or elimination of cold hardening and rolling stress, mechanical performance index reach the corresponding standard.

Cold rolled plate punching net surface quality, appearance, size accuracy than the hot plate, and the thickness of the product right rolling thin to about 0.18mm, so favored by the majority of users. In cold rolled steel as substrate products deep processing, has become a high added value products. Such as galvanized, hot galvanized, fingerprint resistant electro galvanized, color coated steel coils and composite steel plate, PVC Fumo plate, so that the product has beautiful appearance, high corrosion resistance and excellent quality, has been widely applied. Cold rolled steel coil annealing must be carried out after finishing, including cutting head, tail, edge cutting, leveling, leveling, heavy volume, or longitudinal shear panels. Cold rolled plate punching net is widely used in automobile manufacturing, household appliances, instruments, building switch, office furniture and other industries.
