摘要:
The invention relates to a powder substantially consisting of boron nitride aggregates. Said powder has an overall chemical composition of 40 to 45 wt.% boron, 53 to 57 wt.% nitrogen, less than 400 ppm calcium, less than 5 wt.% other elements in total, and more than 90 wt.% boron nitride, limits included, and, in weight percent and on the basis of all the crystallized phases, mean circularity greater than or equal to 0.90, a median pore size less than or equal to 0.5 µm, and open porosity less than or equal to 55%.
摘要:
The present invention provides marble chips produced by hardening resin composition containing binders and reactive monomers, wherein said binders contain halogenated alkoxylated diacrylate oligomers. The marble chips of the present invention can be formed into a uniform pattern, regardless of the time taken for hardening or molding. Therefore, an artificial marble using the marble chips of the present invention may have an outer appearance and texture the same as those of engineered stone, and also present theremoformability and workability characteristics which are advantages of an artificial acrylic marble.
