摘要:
The invention relates to an abrasive having a base body and abrasive particles applied to the surface of the base body, characterized in that the base body has a multicellular structure. The invention further relates to a process for producing this abrasive and to a grinding tool based on this abrasive.
摘要:
The disclosure is directed to an abrasive article. The abrasive article includes a backing having a major surface and a make layer. The make layer is disposed over the major surface of the backing. The make layer includes abrasive grains and a photoinitiator that increases the depth of ultraviolet cure of the make layer by at least about 50% compared to bis(2,4,6-trimethyl benzoyl) phenyl phosphine oxide. The disclosure is also directed to a method for forming the abrasive article.
摘要:
A polishing device is provided which is attachable to a tip holder plate of a concrete polishing machine to polish a concrete surface. The polishing device includes a tip holder that is compression-molded using a heat resistant plastic material to include a plurality of tip support portions. A plurality of polishing tips are inserted into and bonded with the tip support portions of the tip holder with the polishing tips protruding out from the tip support portions when unworn. After the polishing tips are worn an initial amount from polishing the concrete surface, the tip support portions of the tip holder and the polishing tips are adapted to collectively grind the concrete surface.

An abrasive article includes a polymer binder, an infrared radiation absorbing dye, and abrasive grains. In particular embodiments, the abrasive articles have been at least partially cured using infrared radiation. The abrasive articles of the present invention can include, for example, coated abrasives, structured abrasives, and bonded abrasives. Methods for manufacturing abrasive articles include at least partially curing an article that includes a polymer binder precursor, an infrared radiation absorbing dye, and abrasive grains using infrared radiation.
摘要:
Superabrasive tools having improved caustic resistance and their methods of manufacture are disclosed. One aspect may include a method of providing caustic resistance along an entire working surface of a superabrasive tool having embedded superabrasive particles. Such a method may include forming a protective layer through reaction between a reactive source and a reactive element in situ along substantially all of the working surface at an interface between the reactive source and a support matrix including the reactive element, and between each of a plurality of superabrasive particles and the support matrix. At least a portion of the reactive source may then be removed to expose the protective layer. In some aspects, the protective layer may be substantially continuous.
摘要:
Provided is a polyurethane polishing pad. More specifically, the present invention provides a polyurethane polishing pad having an interpenetrating network structure of a vinyl polymer with a polyurethane matrix via radical polymerization and having no pores and gas bubbles. The polyurethane polishing pad having an interpenetrating network structure of a vinyl polymer exhibits uniform dispersibility and reduced changes in hardness of the urethane pad due to heat and slurry, thereby resulting in no deterioration of polishing efficiency due to abrasion heat and solubility in the slurry upon polishing, and also enables a high-temperature polishing operation. Further, according to the present invention, the interpenetrating network structure leads to an improved polishing rate and abrasion performance, thereby significantly increasing the service life of the polishing pad.
摘要:
An article of manufacture and apparatus are provided for planarizing a substrate surface. In one aspect, an article of manufacture is provided for polishing a substrate including polishing article comprising a body having at least a partially conductive surface adapted to polish the substrate. A plurality of perforations may be formed in the polishing article for flow of material therethrough. An electrode is also exposed to the polishing surface by at least a portion of the plurality of perforations. The article of manufacture may also include a polishing surface having a plurality of grooves, wherein a portion of the plurality of grooves intersect with a portion of the plurality of perforations.
摘要:
An abrasive article includes a substrate having opposed first and second surfaces, a make coat on at least a portion of the first surface, abrasive mineral particles on at least a portion of the make coat to provide an abrasive surface and a size coat arranged over at least a portion of the abrasive surface, wherein the size coat has a Young's modulus of less than 100,000 psi.
