peel method
2.A detailed introduction was made to the properties of the wet coated sand suitable for multi-station shell mould shooting machine; the development of a sort of high strength coated sand with low resin content: the shaping index and wetness adjusting process: analysis and prevention of peel back defect of shells made with overturning hopper process; test method of peel back resistance of coated sand: pinhole defect analysis of high Ni ductile iron shell mould castings and application of anti-pinhole coated sand.
5.In order to cleaning up the residue bringing by slewing construction,adopt slurry to wash the scruff in positive circulation craftwork,this method has strict demand of slurry thickness and density, and can easily make the bottom of bore have overfull residue and mud peel,all these would make bearing capacity reduce.
6.The nonwoven fabric,cork paper and the vinylacetate/ethylene(VAE) emulsion are selected as raw materials,using the orthogonal design method to research the influence of the gelatinized quantity,the heating temperature,the heating time,the pressure and the number of the rollings to the peel intensity,the bending intensity and the strength intensity of the nonwoven fabric/cork paper composite product.
