The invention relates to a manufacturing method and a manufacturing system for a solar cell back plate. The method is to use a reactive hot-melt adhesive to composite a first film material and a second film material into one body by pressing. The manufacturing system includes a heating type coating device and a hot-melt adhesive machine connected to the heating type coating device. The hot-melt adhesive machine conveys the reactive hot-melt adhesive heated to a fluid state to the heating type coating device. Compared with the prior art, the manufacturing method of the invention does not need the addition of a solvent to prepare the adhesive, no solvent volatilization exists in the compounding process, and drying process and drying equipment are not needed, which can reduce the energy consumption and the production cost, reduce the land occupation area of the equipment and improve the production efficiency and the product quality. The manufactured back plate has good weatherability, which prevents the back plate from peeling off and effectively prolongs the service life of a solar cell.

The invention relates to a glass steel ship and boat with a PP composite board. The ship body PP composite board and a function area are included. The function area is arranged on the inner side of the ship body PP composite board. A ship resin mixture layer is arranged on the surface of a honeycomb plate in a brush application manner, and a horsehair roller is utilized for repeated piercing typerolling.
