A cleaning system for removing abrading material adapted to remove and keep separated the abrasive contaminants from a wash rag, mitt, or brush which is capable of being mounted within a standard 5 gallon bucket for the purposes of washing a car, boat, recreational vehicle or the like. The cleaning system is a lattice structure including a scrubber grate which is positioned within the bucket such that a wash rag, mitt, or long handled brush is capable of being vigorously rubbed against the scrubber grate such that any abrasive grit or contaminants within the wash rag, mitt, or long handled brush will become dislodged and settle to the bottom of the cleaning fluid within the bucket. The lattice structure also has a receiver base to support the scrubber grate and is located near the bottom of the bucket. The lattice structure receiver base allows abrasive contaminants and debris to settle to the bottom of the bucket. The lattice structure receiver base cross-bar structure results in dampening the agitation of the cleaning fluid below the receiver base causing the abrasive contaminants to remain near the bottom of the bucket.

The invention discloses a microcellular foaming injection molding technology capable of realizing high surface glossiness and high bubble density as well as a mold. The technology comprises steps as follows: a physical foaming agent or a chemical foaming agent is evenly mixed with polymer melt in a high-pressure environment by the aid of a microcellular foaming injection molding machine; the temperature of a mold is increased, high-pressure gas is introduced into a cavity of the mold, the polymer melt smaller than the total volume of the cavity of the mold is injected into the cavity of the mold, and foaming space is reserved; the high-temperature state of the wall surface of the cavity of the mold is kept, gas channels located on a moving mold side wall surface of the cavity of the mold and a parting surface of the mold are opened in a matched manner, a gas is controlled to enter and leave the cavity of the mold, and the polymer melt is controlled to flow, so that the reserved foaming space is transferred to the moving mold side of the cavity of the mold; the mold is cooled, when the temperature of the melt is decreased to the foaming temperature, all gas channels of the mold are opened, gas inside the reserved space is exhausted, and a polymer foams and fills rest space of the cavity of the moving mold. The technology can prevent dynamic foaming and promote static foaming and can be used for producing plastic products with the high surface glossiness and the high inside bubble density.

[Problem] An object is to provide a polishing composition which can improve smoothness of a surface of an alloy material to obtain a highly glossy surface, and can obtain a high-quality mirror surface having significantly reduced scratches or the like.[Solution] There is provided a polishing composition which is used for polishing an alloy material, and which comprises abrasive grains and an additive which does not form a complex with specific metal species and is adsorbed on a surface of the alloy to exhibit an anticorrosive effect.

A terpolymer composition is described that contains a statistical amount of 50-98 wt % of a first repeating AA-BB comonomer unit; 1-25 wt % of a second repeating AA-BB comonomer unit; and 1-25 wt % of a repeating lactam comonomer unit or 1-25 wt % of a third repeating AA-BB comonomer unit, where the terpolymer composition exhibits a high melting point similar to that of PA66 while also exhibiting a significantly reduced crystallization rate and crystallization temperature.
