我们采用有机玻璃制做了一套化工生产流程投影片。按生产流程图把有机玻璃粘成双层或三层,使带有气泡的液体在原料的入口处流进,按化工生产流程线在夹层中川流不息,最后在形成产品或废料的地方排出。将以上过程投影在银幕上,可把构造原理、生产流程形象生动地展现在面前。下面以硫酸的工业制法为例,介绍制做和使用方法如下:
We used plexiglass to make a chemical production process slide. According to the production flow chart, the plexiglass is glued into two or three layers, so that the liquid with air bubbles flows into the inlet of the raw material, flows in the interlayer through the chemical production flow line, and is discharged at the place where the product or the waste is formed. Projecting the above process on the screen can vividly show the principle of construction and the image of the production process. The following is an example of the industrial production method of sulfuric acid. The methods of production and use are described as follows:
