Tungsten boat can also be called evaporation boat, evaporation tungsten boat or coating tungsten boat, by tungsten sheet through high temperature stamping molding, stamping boat, folding boat, welding boat, riveting boat and other types.
Tungsten boat has good conductivity, thermal conductivity, high temperature resistance, wear resistance, corrosion resistance, such as performance, and therefore is widely used to control mirror, gold-plated, evaporator, imaging heating container, spray paint of electron beam, household appliances (shell), mobile phones, toys, and various accessories such as vacuum coating industry and sintering furnace for sintering or vacuum annealing in ship industry.
In the ideal (vacuum, dry) state, wire is connected to both ends of the tungsten boat and electricity is energized. The metal with low melting point is placed in the middle of the concave. When the temperature rises below 2000 degrees, the metal will evaporate into gas and be plated on the surface of the metal workpiece.
The brand name of Tungsten boat was named WZO according to the Chinese phonetic alphabet of "Tungsten" and "zhou". The type of tungsten boat is represented by "V" and "U", and the different types under each type are represented by Roman numerals ⅰ, ⅱ, ⅲ... To represent. Tungsten boat specifications are represented by numbers in the format of "-boat wall thickness -boat width". Use and brand, model corresponding. For example, WZO-V- ⅰ -02-17, the name of the tungsten boat is WZO, V-type without blank holder, 0.3mm tungsten boat wall thickness, 15mm tungsten boat width. The second is the surface quality of tungsten boat. The surface of the tungsten boat shall always be clean and the color shall be silver-white metallic luster. The area of unpolished points in the electrolytically polished tungsten boat shall be less than 2mm3. Tungsten boat surface should not have cracking, delamination, cracking, missing edge, Angle and other defects. All parts of the tungsten boat should not have burrs. The performance of tungsten plate used for making tungsten boat should meet the requirements of national TUNGSTEN plate GB3875. To use the precision of 0.02mm and 0.01mm caliper and micrometer tungsten boat size for measurement. Tungsten boat standard is measured according to national GB4196 standard. The weight of the tungsten boat should be weighed by a balance, and the weight of the balance should be 0.2g. When the chemical composition of tungsten boat is qualified, the melting point of tungsten boat can not be measured.
