Abstract
The utility model discloses a tungsten boat with a cover. The tungsten boat is provided with a tungsten boat cover and a tungsten boat body, wherein the tungsten boat cover is provided with evaporation holes. According to the tungsten boat with the cover, raw materials can be effectively prevented from splashing out of the tungsten boat, so that the quality of finished products is guaranteed and the raw materials are saved.
Description
Technical field
The utility model relates to a kind of tungsten boat with cover, is applied to the film preparation field.
Background technology
In the film preparation process, need very strong power just can make raw metal from the solid state carburation by evaporation.But existing tungsten boat container is often superficial short, raw metal often easily spills outside the tungsten boat in heat-processed like this, make like this insufficient raw material in the tungsten boat, may cause coating film thickness inadequate, perhaps surplus stock (as the silver material) blackening flavescence, both waste valuable raw metal, affected again effective workpiece.
Therefore, need a kind of new product to address the above problem.
The utility model content
The purpose of this utility model is the deficiency that exists for prior art, and a kind of easy to use, economical and practical tungsten boat product with cover is provided.
For achieving the above object, the utility model tungsten boat with cover can adopt following technical scheme:
A kind of tungsten boat with cover has tungsten boat lid and tungsten boat body, and the tungsten boat covers and is provided with evaporation apertures.
Beneficial effect: the utility model can prevent effectively that raw material from spilling the tungsten boat, has both guaranteed final product quality, has saved again raw material.
Preferably, evaporation apertures is circular hole, and the aperture of circular hole is 1mm, and pitch of holes is 2mm.
Preferably, evaporation apertures is window shutter, the wide 1mm of the window of window shutter, and the window spacing is 2mm.
Description of drawings
Fig. 1 is the structural representation of tungsten boat with cover of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
See also shown in Figure 1ly, a kind of tungsten boat with cover has tungsten boat lid 1 and tungsten boat body 2, and tungsten boat lid 1 is provided with evaporation apertures.Evaporation apertures is circular hole, and the aperture of circular hole is 1mm, and pitch of holes is 2mm.Evaporation apertures is window shutter, the wide 1mm of the window of window shutter, and the window spacing is 2mm.
All greater than 1mm, therefore, this set can prevent effectively that material from spilling the tungsten boat due to the cross section of the material that adopts in the coating process process.
As mentioned above, the utility model can prevent effectively that raw material from spilling the tungsten boat, has guaranteed final product quality, has saved again raw material.
