Abstract:
An inner surface super-finishing apparatus includes: an inner surface grinder (200) including: a film grinding material (202) grinding a surface of the object; a feeding roller (204) for feeding the film grinding material (202); a collecting roller (206) for collecting the film grinding material (202) used for grinding the object; supporting rollers (208) and (208') for supporting the film grinding material (202); a grinding head (210) protruding to one side and supporting the film grinding material (202) such that the film grinding material (202) contacts an inner surface of the object; a plunger (220) for supporting the grinding head (210); and a shaking member (230) installed on a right side of the plunger (220), for allowing the plunger (220) to reciprocate in a predetermined interval; a horizontal transferring member (110) for forcing horizontal movement of the inner surface grinder (200); a back- and- forth transferring member (130) for forcing back- and- forth movement of the inner surface grinder (200); and an object supporting member (280) installed on one side of the inner surface grinder (200), for supporting and rotating the object (W).
Abstract:
The present invention provides a bleach activator which is at least one macroyclic manganese comple selected from the group consisting of [Mn III (rac-14-decane)X 2 ]Y, [Mn III (mes-14-decane)X 2 ]Y.H 2 O and [Mn III (mes-14-decane)X 2 ]Y represented by Formulas 1-3, as well as a preparation method thereof. Also, the invention provides a bleaching composition and bleaching detergent composition comprising the bleach activator. The bleach activator comprising the manganese complex is used in a granulated form. Wherein X is at least one selected from chlorine (-Cl) and acetate (-OOCCH 3 ), and Y is an anion selected from Cl - , Br - , F - , NO 3 - , ClO 4 - , OH - , NCS - , N 3 - , and PF 6 - .
