This paper has studied the technological process for preparation of grain potassium picrate (PK), which can meet the requirements of production in batches.
The machine can finish the moulding and processing of heteromorphosis iron craftwork with good consistency, and can process parts in batches and high efficiency.
The welding machine has strong anti-electricity fluctuation ability,it is available to produce in small quantity.At the same time,further research should be held on accurancy accouplement.
The experiment show that this algorithm divides the image into a lot of unit grids,rectifies grid one by one,guarantees the rectificative precision,improves the rectificative efficiency.
This paper compared with several ways of yeastiness, determined the yeasty method using old pickle to add matural water,which suits large quantity of production in industrialization.
The PP armchair produced by this special compound has a good impact resistance, high strength, good ageing resistance, good corrosion resistance and dimensional stability and good lighteness.
