Metal
There are copper mesh belt, mesh belt conveyor, nickel, chrome mesh belt, memory, mesh belt, stainless steel, open gold conveyor, conveyor and so on platinum.
Copper mesh with a mixture of copper and other metal materials. There are zinc copper-nickel alloy (copper nickel zinc mesh belt), brass, copper and nickel zinc tin belt, bronze, nickel, copper mesh belt.
Monel mesh belt material produced by this belt conveyor easy processing, and is highly resistant to erosion of the mesh belt, the less flexible, generally as a high-grade mesh belt conveyor materials.
Ni-Cr-mesh belt, also known as the new mesh belt, glory as silver white, are less flexible.
Memory mesh belt with a super-elastic, bending or tension when the force after relaxation, shape forgetfulness will network with restitution.
Titanium conveyor kinds of ultra-lightweight titanium is the metal, there are no other material compared to lightweight, flexible, than any other metal is more resistant to erosion, on the sweat, is more wear resistant than steel. Corrosion of titanium can block out 100 percent more effective than platinum.
Kaijin is golden conveyor belt as raw material in the mesh-belt conveyor. Because pure gold is very soft, so do with gold mesh belt conveyor, generally you want to add silver, steel or other metals to increase strength and toughness. Now, Kaijin commonly used as a conveyor of metal surface treatment material.
Platinum conveyor conveyor Platinum is a kind of white metal heavier and the price of expensive quality and purity of 95%.

Stainless Steel
Mainly acetate fiber mesh belt conveyor, according to the different manufacturing process can be divided into plate conveyor, plastic conveyor.
Plate conveyor with cellulose acetate sheet cutting the mesh-belt conveyor. Plate is characterized by easy burning, relatively light, almost no exposure to UV discoloration, hardness greater good gloss, durable, easy to heat processing, the more beautiful style, wearing not easily deformed.
Molding conveyor with cellulose acetate particles using extrusion and injection molding machines.
Conveyor belt material quality requirements are as follows:
* Mesh belt conveyor various parts of a flexible and robust
* Light
* Anti-erosion function fine, which will be mesh belt conveyor is not easy getting old, but also to protect the mesh belt conveyor from the corrosion of chemical substances (which can also plated with the appropriate film)
1, the metal mesh belt conveyor
(1) Processing Method
Mainly by the parts processing, assembly, polishing and surface treatment composed of four processes. A mesh belt conveyor is usually two, composed of 30 kinds of parts, mainly mesh belt ring, mesh belt feet, nose care, hinges, locking block and screws and so on.
Part of materials directly determine the functional and dimensional accuracy of the latter working procedure of the processing technology and the ultimate product quality, and therefore part machining process is essential. Constitutes a part of the net with a choice of metallic materials, mainly based on material indicators of strengths and weaknesses, namely: mechanical function (including strength, elasticity, plasticity), craft-oriented (including cold, heat processing formability), resistance to erosion, welding, machining, wear resistance, electroplating sex, color and so on. Network with metal materials, the continuous development of research centered around the above function, progress to be achieved.
(2) Surface treatment
Metal mesh belt conveyor is generally based on the manufacture of a metal as the substrate, and then its surface treatment, surface treatment methods basically are as follows:
1) Package Gold: also known as laced with gold, that is, the substrate on the packets (paste) gold belt (on gold) of the sheet, a thickness of 10 ~ 5Oum.
Gold-representation of two ways, one of the pack to open gold accounts for mesh belt conveyor weight ratio, like 1 / 10 l2K, This shows that the mesh belt conveyor 12 to open one-tenth of the weight of gold; the second is to use pure Gold weight accounted for mesh belt conveyor, said the ratio of the weight is like 50/1000, which indicates that the Internet gold belt conveyor weight of 5%.
2) Plating: The principles of electrochemistry will be a metal coating on the substrate surface treatment methods, like gold, Ti-coated, black chrome plating and so on. With gold-plated, for example, in the other metal materials made of mesh-belt conveyor gold, Ti-coated, black chrome plating and so on. To improve the appearance, at the same time to make it resistant to erosion characteristics of gold. Gold-plated and gold color with one of them to open other types of metals related to the partial quantity zinc white, and copper content and more yellowish.
3) Coloring: also known as the spray painted, spraying right through the mesh belt conveyor of the substrate surface treatment methods. Like epoxy resin powder coating, stainless steel spray coloring and so on. This approach can be fruitful not only glory, but also multiple layers of shading.
2, stainless steel mesh belt conveyor
(1) Processing Method
1) In the stainless steel plate on the frame and put the net with a mesh belt legs cut out and put together with hinges. Such processing methods and good quality products, but the capital high, suitable for small quantities produced.
2) injection molding, the stainless steel softened, forging into a vacuum mold. A high degree of automation of such processing methods, capital is low, suitable for high-volume producer.

2, mesh belt mesh belt sheet materials, the development of
Preface: a living thing there is no hard and fast alone a permanent is change. It is progressive, innovative incentives to promote the social wheels forward. Mesh belt mesh belt exactly the history of film material is of such. At present, in Western countries, as a medical tool, mesh belt usage rate second only to aspirin; in our country, the need to wear a belt around more than 400 million persons. Mesh belt mesh belt sheet materials can be divided into a natural medium, optical mesh belt conveyor, resin. Natural optical media has long been replaced by conveyor belt. This article only on the optical mesh belt conveyor, resin history, classification, characteristics and prospects for future development to be brief.
1. Optical mesh belt conveyor
(A) optical mesh belt conveyor History
Around the end of the thirteenth century, because of the lack of homogeneity of high-quality optical mesh belt conveyors, mesh with the invention is limited to correction of presbyopia. Until 1608, Calileo invention of long-term perspective mesh belt, mesh belt conveyor optical raised very high quality requirements, thus contributing to the Net with a sheet material manufacturing process breakthrough. The seventeenth century, Fraunhofer study the mesh belt conveyor of the solar spectrum of the refraction, dispersion, and long-term perspective mesh belt mesh belt piece of dispersion corrected. In 1757, Dolland with the crown mesh belt conveyor, chert belt conveyor belt system became a non-color sheet. In 1880, Abbe Xian-rong, a high refractive index optical mesh-belt conveyor, there was no significant corresponding increase in the dispersion. Since then, the German company Carl Zeiss to produce such a mesh belt conveyor belt penetration. Into the twentieth century, optical mesh belt conveyor mass produced and variety, as the mesh belt mesh belt piece of material, its quality requirements in order to have good optical function-based, such as refractive index, dispersion and so on.
(B) optical mesh belt conveyor varieties
Optical mesh belt conveyor of the most important feature is the refractive index n, dispersion (with Abbe number to represent the reciprocal of V) and the proportion of SG.
nd = the speed of light in vacuum helium / optical media in helium the speed of light.
Vd = (nd-1) / (nf-nc)
Where c, f two lines for the red and blue two-color, with a wavelength of 486nm, 656nm. V value is high, then low dispersion.
SG is the volume of objects such as the ratio of the weight of the water. At present, the Abbe number "50 optical mesh belt conveyor belt commonly known as crown conveyor, while the Abbe number" 50 optical mesh belt conveyor belt conveyor known as flint, but not all optical network with a conveyor are here to classify the most commonly used method is to use six-digit mark, the former three-digit decimal that the refractive index of the sector, said the Abbe, after three-digit number, such as the mesh belt mesh belt conveyor crown logo 523.59 thousand .
Market, extensive use of optical mesh belt conveyor belt is mainly crown mesh belt conveyor, chert belt conveyor and conveyor belt corona, No. 3 kinds of material. Crown mesh belt conveyor, the refractive index of 1.523, Abbe number of 59, mainly for optical networks with single-, double-optical network with a focus on networks and multi-band, as the far-zone. Flint mesh belt conveyor, a high refractive index (about 1.580 ~ 1.690), large dispersion (Abbe number is small, about 30 ~ 40), mainly for the production of fusion pairs of optical network with a sub-film, a high percentage of net zone plate (high refractive index can mesh belt thickness thinning, although the weight increase). No. Mian mesh belt conveyor, refractive index 1.541 ~ 1.616, Abbe number 55 ~ 59, mainly for the production of integrated dual-band sub-chip optical networks. In recent years, a number of high refractive index optical mesh belt conveyor belt pile up and absorption of penetrating into the market, the former n-as 1.60,1.70,1.80, can reduce the number of nets with a high degree of film thickness; the latter is in the original optical mesh belt conveyor machine materials by adding metal oxides to absorb ultraviolet light.
(C) optical mesh belt conveyor features and defects
Optical mesh belt conveyor should have the following characteristics:
1. Homogeneity (chemical composition and physical state of uniformity) if the net with a sheet material existence of fissures, bubbles, impurities, turbidity, deformation and so on, will be the severe impact of optical functions.
2. The appropriate refractive index and wavelength dispersion values of the refractive index decreased with the increase, the refractive index is usually the higher the dispersion is gradually increasing. For example, optical mesh belt conveyor refractive index of 1.80, Abbe number of 32 ~ 35.4, patients often complain of vision when wearing a belt of interference by the color stripes. The refractive index also increased the proportion of increase is usually so high refractive index belt thickness is thinner, but the weight is heavier.
3. A transparent optical mesh belt conveyor of the light transmission rate of 92%, high refractive index optical mesh belt conveyor increased due to reflections caused by light transmission rate has dropped, in addition, the thicker the belt piece, because light absorption, light transmission rate will be reduced.
4. Institute of Chemical Physics chaos of optical mesh belt conveyor should be effective and durable to withstand the impact of weather and does not color, not fading. In terms of dual-band optical networks, sub-piece with the main sheet should have the same expansion rate.
(D) optical mesh belt conveyor of the hardness
Optical mesh belt conveyor theoretical tensile strength is very high, more than 4 million lbs / square inch, but in fact in 2000, and 10000 lb / square inch occurs when the rupture, and the optical mesh belt conveyor without toughness, brittle high - . Optical mesh belt conveyor of the impact force depends on its surface and edge quality. The U.S. FDA on the net with a sheet strength to make a strict delineation of scale in order to minimize or avoid the net with a broken piece caused a severe eye injury.
(E) optical mesh belt conveyor gradually being replaced by resin
Along with the increasing development of science and technology, ophthalmology, optical, manufacturing processes such as knowledge and learning has improved steadily, in-depth information on the eye as a light receiving infected with emotion experienced by the optical devices are increasingly being familiar with the mechanisms of injury, UV radiation, with only solar energy 5%, but the eye of the most damaging. Eye refractive medium can absorb UV-largest sector, but there is still a small sector ultraviolet light reach the retina, leading to a chronic retinal light damage. Therefore, the net belt as the correction of refractive errors, presbyopia and other medical tools, the ideal network should not only have a perfect zone plate optical functions, light weight, thin, and must have the absorption of UV light, sufficient impact resistance and so on. Optical mesh belt conveyor belt mesh belt as a film material, there are many insurmountable shortcomings, therefore, currently on the market year by year, according to the rate of decline in net with a resin film is emerged.
二. Resin net zone plate
(A) History
With optical mesh belt conveyor analogy, resin net with a very short history of film. As the First World War contributed to the U.S. optical mesh belt conveyor industry, the development of World War II, the United States promoted the resin industry. In 1947, Colombia resin (Columbia Resin 39, CR-39) has begun as a mesh belt mesh belt sheet material application; in 1978, the metal mesh belt (Polycarbonate Resin) come out. Because the U.S. FDA on the net with a piece of the impact resistance of the testing requirements, large net with a piece of the epidemic, as well as fashion can be effectively dyed resin net with a piece of the growing demand, the market year after year, according to the rate of expansion.
(B) optical and physical properties
1. Columbia resin CR-39 refractive index of 1.498, Abbe number of 58, accounting for 1.32. It has the following advantages: ① light weight (low weight), its weight is about other specifications crown half of the mesh belt conveyor; ② has a strong impact resistance, even if broken, debris than the blunt edge; ③ inert chemical function ; ④ due to the low thermal conductivity, has good anti-fog function; ⑤ net zone plate design diversity; ⑥ anti-depression, because of the surface elasticity, the impact of high-speed particles could be rebound, not easy to damage the surface. However, CR-39 also has some disadvantages: ① net zone plates surface, easy to wear, to go through to improve the coating; ② due to the refractive index is relatively low net with a piece of relatively thick, mesh with the larger piece, the thicker the edge, wearers often complain not pretty; ③ index of refraction affected by temperature. 80 years, CR-39 in the U.S. market, according to a rate of about 90%.
2. Wire mesh belt (Polycarbonate Resin) refractive index of 1.586, specific gravity of 1.20, lighter, thinner thickness. Because the metal mesh belt mesh belt-chip surface is relatively soft and easy to wear, so net surface to be coated with a film of anti-friction film. The material net zone plate can absorb UV light to help prevent eye damage. Network with on-chip refractive index of the material, hence the reflection rate is high, will have to be AR coated membrane. Its biggest strengths is a very good impact resistance. The disadvantage is mainly a low Abbe line, dispersion, hence easy to lead around the chromatic aberration. While consumers rarely complain chromatic aberration, but still should tell consumers to color the title and the possibility of decline in peripheral vision. Into the 90's, in the U.S. market, the metal mesh belt is gradually replacing the CR-39's dominant position, has been widely used in optical networks with single-and multi-mesh belt and the focus of multi-focal gradient mesh belt, it has better security.
三. Mesh belt mesh belt sheet materials, the development of long-term
At present, the metal mesh belt is ideal net zone plate material. However, change is eternal, and society is continually improving, mesh belt mesh belt sheet material development will continue to tend to idealize. At present, because the metal mesh belt mesh belt feature film is superior to other network zone plate material, therefore, have a better market prospects
