Classification of printing light source

In the printing process, special light sources can be used for UV light curing of coatings on printing surfaces, color printing, paper packaging, decorative materials, printed tin cans, etc .; also used for non-silver salt negative film, diazonium salt film, film, resin plate, PS Exposure, exposure, etc. There are many special light source products, which are applied to different printing links according to their respective parameter characteristics. Here are three special light sources for plate making, printing, and light curing. Now let's take a look at their style.

One: plate making light source

Common plate-making light sources are mainly divided into five categories. The first category is incandescent lamps, infrared lamps, tungsten halogen lamps; the second category is mercury lamps; the third category is metal halide lamps; the fourth category is xenon lamps; the fifth category is lasers for plate making.

Two: printing light source

Commonly used light sources for printing are: carbon lamp, high-pressure mercury lamp, hernia lamp, fluorescent lamp (cold light lamp), metal halogen lamp.

Three: UV light curing light source

There are two types of light sources for UV hardening materials: electrode type UV light source (ArcUVLamp), electrodeless type UV light source (Electrode-lessUVLamp).

The electrode-type UV light source is made of a quartz tube. After evacuation, a certain amount of mercury is injected or filled with some special materials. One electrode is placed at each end and sealed. The electrodes at the two ends are then insulated with ceramic wires or directly connected with metal connectors. The power supply is connected.

The electrodeless UV light source is made of a quartz tube, after evacuating, injecting a certain amount of mercury or filling some special materials and sealing. There are no electrodes in the lamp. UV light is generated by the microwave excitation of mercury or special materials in the lamp tube.

Technics: Spun-bonded Raw material: 50% polyethylene and 50% polyester chips(slices) Pattern: Embossed Style: Dot Width: 130''(3.3m, can be split) Feature: Hydrophobic, water-resistant, breathable, anti-tear, anti-pull, high-temperature resistant, high-strength, eco-friendly. Use: High-end medical and hygineic products,various kinds of protective clothing, interlining for military garments, auto-upholstery, the backing of composite, lamination, composite materials. Weight rang: 10-120g/m2 Place of origin:China Model No.: ET-Z Supply ability: Around 30 tons each day. This means 12,000tons each year. PE/PET Bicomponent Spunbonded Nonwoven Fabric.easy self-sealing, high tensile strength, good handfeeling, and etc... Good physical properties: 1. We adapted the PE as the component of the sheath. Its has lower melting point than PET. In some way, itself is a binder. It could be self-sealing without need any glue. Softness and pleasant feeling in lightweight basis weight make your products fashionable and attractive. 2.Higher elasticity. 3. No residue, no shedding. 4. Good sealing performance. Higher possibilities of binding(polyethylene) with other materials for composite fabric in automotive or building industies. 5. Good laminating properties. 6. Excellent hydrophobic properties. 7. Excellent, comfort qualities in contact with the most sensitive parts of human skin. 8. Non-toxic, non-stimulated, can effectively protect the human skin. Our soft Soft PE/PET sheath-core spunbonded bicomponent nonwoven fabrics are hydrophobic, it is uesed as the protecting media of LCD screen, digital product and etc... Specification: Product Name PE/PET sheath-core bicomponent Spunbond Nonwoven Fabric(filament nonwoven fabric) Article No ET-Z Basis Weight 10-120g/m2 Max Width 3.3m(130'')-we can cut it into small rolls for free Roll Length According to customers' request Color Original color is white. Any color is available but with addtional cost. Melting Point Around 130 Centigrade Minimum Order 1 ton in white and 5 tons in other color Price Term FOB Ningbo or Shanghai Port Payments Our payments are delivery against the payment with 30% deposite or L/C at sight Delivery Cycle 7 to 30 days Characteristics: The products inherited the advantages of the traditional textile methods and also developed it. Sheath-core bicomponent filament fibers are those fibers where one of the components (core) is fully surrounded by the second component (sheath). The filament fibers are bonded together by hot thermally calendaring. This largely increased the softness and tensile strength. Softness: The sheath of the sheath-core bicomponent nonwovens is polyethylene. It has lower melting point and softness properties. Excellent hydrophobic properties: The raw materials of the spunbonded nonwovens are hydrophobic polyethylene, polypropylene and polyester. No additives are added during the production processing. Good laminating properties: Bicomponent PE/PET nonwovens are sheath-core structure. The component of the sheath is polyethylene. It has lower melting point. The component of the core is polyester. Just because these two materials have higher melting point. So, it maintains the high tensile strength and also has good laminating properties. The melting point of the sheath and core difference between 30 to 130 degrees centigrade. Hence, the production process is easy to control. Composite processing is including cast, ultrasonic and thermal compound method and others. Applications: special bags for protecting electronic products, composite material, coating, substrate material,Disposable Baby Diapers, feminine hygiene, surgical gowns, various protective clothing, composite packaging materials, clothing interlinings infiltration media and so on. Because no spinning additives are added during the process, so it has no harm to human skin. We can produce ET bicomponent nonwoven fabric with thickness of 0.8 denier, in the weight of 10 to 150gsm and the width of 5 to 320cm.
