As the social economy tends to develop more internationally and professionally and with more technology adopted, enterprises need to exchange more with the outside word in the aspect of technology, personnel, information and other materials.
By the application of other advanced technology, IT, software technology and advanced manufacturing technology should be popularized in manufacturing industry so that comprehensive support ability in the aspect of scientific technology, process design, materials and manufacture will be reinforced on the whole.

D. [10, 11] provided a method to isolate isopimaric acid using P. elliottii rosin as raw material and 2-amino-2-methyl-1-propanol as reagent.
Other materials were obtained from commercial sources and used without further purification.
In addition, the isomerization and dehydrogenation of abietic acid in raw material was also observed.

(2) Some of the fluorosilicic acid precipitates during the process with sodium or potassium ions as Na2SiF6,K2SiF6or as more complex compounds.The residual fluoride in solution is distributed between the phosphoric acid and the byproduct during its precipitation.Furthmore,the remaining fluorosilicic acid in the phosphoric acid partly decomposes and evades as SiF4and HF.The reaction equation is described as follows: (3) (4) Through the above analysis showed that in wet process acid the fluoride is assumed to be presented as hydrofluoric and fluorosilicic acid.When adding a certain amount of alkaline solution Fluosilicic acid reacts with sodium ion to generated fluorosilicic acid precipitate,and them due to some synergistic reaction of iron calcium magnesium impurities to form the corresponding precipitate. 2 Experimental procedure 2.1 Raw materials
