Abstract: The present invention discloses a metal wire armored optoelectronic hybrid cable, which comprises an optoelectronic hybrid unit, a metal wire armoring and an outer protection casing. The optoelectronic hybrid unit comprises an electrical unit and an optical unit which are mixed. The metal wire armoring wraps the optoelectronic hybrid unit. The outer protection casing wraps the metal wire armoring. In the present invention, due to the use of the metal wire armoring, the bending performance is favorable, the production and processing processes are simple, and the production cost of the hybrid cable is greatly reduced.

Abstract: The present invention discloses an eco-friendly road surface material for thawing ice and snow and the methods of preparing and using the same. The preparation method includes the following steps: 1) adding 10-50 parts of snow thawing substances into 50-100 parts by weight of water, after dissolving the snow thawing substances completely, adding sodium hydroxide solution to adjust the pH value of the mixture to be 8-10, then adding 10-50 parts by weight of support material, and stirring, baking, milling and sieving the mixture to obtain a support powder loaded with snow thawing substances; 2) adding 15-40 parts by weight of the support powder loaded with snow thawing substances into 10-30 parts by weight of cation emulsified asphalt, then adding 10-30 parts by weight of aqueous epoxy resin, 10 to 50 parts by weight of water and the curing agent of aqueous epoxy resin to obtain the coating material for thawing ice and snow.
