Abstract: Disclosed are a phosphaphenanthrene-structure reactive flame retardant and an application thereof. The preparation method comprises: enabling 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO), p-hydroxy benzaldehyde (4-HBA), and 5-aminomethyl-1,3-diphenyl-1,3,5-diphosphonitryl heterocycles to react under a certain condition to obtain the reactive flame retardant with a benzene ring rigid structure containing polyhydroxy. Compared with an ordinary flame retardant, the phosphaphenanthrene-structure reactive flame retardant has the characteristics that polyfunctionality is achieved, the molecular structure is stable, the hydrolysis resistance is better, and less migration in epoxy resin, moreover, the flame retardant property of the epoxy resin can be remarkably improved.

Abstract: The present application provides a method for simultaneously synthesizing a biological flocculant with polysaccharide and ?-PGA as the active components by using Bacillus licheniformis. Bacillus licheniformis is inoculated to a slant culture medium to be cultured; a single colony on a fresh plate is inoculated to a seed culture medium to be cultured; and a seed fermentation broth is inoculated to a fermentation culture medium to be cultured, and then the biological flocculant having two different components is obtained. The flocculant synthesized in the present invention is high in activity and good in thermal stability; and especially, the flocculation effect of polysaccharide is relatively superior under acidic and neutral conditions, and the flocculation activity of ?-PGA is relatively higher under neutral and alkaline environments, which can satisfy a relatively large pH application range.

Abstract: The present invention provides a skin penetration enhancing method and its penetration enhancer which is comprised of sponge spicules or a biologically effective amount of sponge spicules or a combination containing sponge spicules.

Abstract: A method for accurately producing the drilled hole in a wall of a component fabricated by investment casting process, such as for use in a blade or steam turbine includes the following steps. The 3D data of actual component is obtained from the measurements or from the numerical simulation. The actual model and the ideal model are aligned and compared, a series of cutting planes are given to establish a series of 2D cross-sections of the actual and ideal models after registration. Each cross-section is dispersed into discrete points, the distance between each corresponding points are calculated and formed into 2D displacement. The accurate parametric model consisting of the depth, hole center, and the nominal vector is obtained on the basis of considering the deviations in geometrical and positional values. The drilled hole is then produced according to the corrected parametric drilled-hole geometrical and positional value.
