3.Used in shaping process of brick production , the treatedclay will be plastic extruded by up stage then via vacuum room into down stage, estruding into solid or hollow clay column of required cross section and shape which then cut into greenbrecks by green breck cutter.
6.For the machine-squeezed oil, it was first degummed 20 min by 0.04% H3PO4 at 90℃, and neutralized 10 min by 0.15% CaCO3, then treated with 15% bleaching clay, and refined oil could be obtained.
7.The results for rubber seed oil refining were as follows: For the crude solvent-extracted oil, it was first degummed 20 min by 0.04% H3PO4 at 60℃, and neutralized 10 min by 0.15% CaCO_3, then treated with 5% bleaching clay, and refined oil could be obtained.
8.Lube oil distillates,which were from the mixture of Daqing crude oil and Russian crude oil in the different proportion at 350～400℃,400～450℃ and 450～500℃,were treated by acetone-benzol dewaxing,furfural refining and clay refining. The typical base oils were obtained and evaluated.
9.Based on a large oil tank engineering, a design method of composite ground treated with 27m long deep mixing piles in 22m thick mucky clay is discussed and the design formula,which has reference to designer,is put forward with the help of the calculated results and the inspected results.
