为提高手工涂膜质量,使膜剂厚度均匀、含量准确、易于操作,我们制作了可调式涂膜工具。膜具由5mm厚有机玻璃粘合成一长方形槽,(其长度可按玻璃板宽度而定)其控制厚度面由定片b和动片a组成。a片延长的锐角α的正弦为0.1(即Sinα=0.1),a片可沿b片下斜面滑动,上行1mm时,下边可上升0.1mm。见附图 In order to improve the quality of hand-painted film, film thickness uniform, accurate content, easy to operate, we have made adjustable coating tools. Membrane with 5mm thick plexiglass bonded into a rectangular groove, (its length according to the glass width may be) the thickness of its control by the fixed film b and a dynamic film. A piece of extended acute angle α sine 0.1 (ie Sinα = 0.1), a film can slide along the slope of b under the board, the uplink 1mm, the bottom can be increased 0.1mm. see Attachment
