The present disclosure relates to a treating method of a metal surface, and a coating method thereof using the same. A treating method of a metal surface may include grinding solid carbon dioxide and then spraying the ground solid carbon dioxide onto a metal surface. After spraying the ground solid carbon dioxide, irradiating short-wavelength ultraviolet rays on the metal surface, thereby removing foreign substances attached to the metal surface, reforming the metal surface into a hydrophilic surface and improving wettability of a coating material.

The drain-unclogging straw is a chemical device. The drain-unclogging straw comprises a drain clearing device and a domestic DWV system. The domestic DWV system further comprises a drain. The drain contains biochemically-generated material that inhibits the flow of wastewater through the drain. The drain clearing device is a chemical device that is formed as a kit. The drain clearing device breaks the biochemically-generated material down into components that will flow through the drain. The drain clearing device comprises a straw and a chemical compound. The chemical compound is in a solid phase. The straw contains the chemical compound. The straw is placed directly in the drain. Once in the drain, the straw dissolves such that the chemical compound is released into the drain. The chemical compound chemically interacts with the biochemically-generated material such that the biochemically-generated material is broken down.

A polymer may have a molecular mass of less than 8,000 g/mol and a polymolecularity index PI of less than 3, produced by free radical polymerization, in water, and at a temperature higher than 50 C., of at least one anionic monomer comprising at least one polymerizable olefinic unsaturation and at least one carboxylic acid function, in the presence of phosphorus with a degree of oxidation I, phosphorus with a degree of oxidation III and a radical-generating compound. Such polymers may be produced and use for grinding mineral matter, as a detergent agent, or as an anti-scaling agent.
