The present invention provides a purification device for solar ammonia decomposition hydrogen production, comprising: several energy collection portions, wherein a lower 5 half portion of the energy collection portion is buried in the ground, and an upper half portion of the energy collection portion is exposed to the ground to reflect sunlight, and a reaction tower capable of receiving sunlight reflected by the energy collection portions for hydrogen production by a thermochemical method. The energy collection portions are provided around the reaction tower, and adjacent energy collection 10 portions located in the front-rear direction are provided in a fitting manner so that the energy collection portions can support each other in wind sand. By the arrangement of the energy collection portions, a completed heliostat field can be obtained so that sunlight is reflected to the reaction tower, and the reaction tower can acquire energy for hydrogen production.

Cubierta de muros y método para producir la misma

Un revestimiento de paredes, un método para producirlo y un método para revestir una pared. El revestimiento de pared comprende un sustrato plano, tal como un sustrato base no tejido, que tiene un frente y una parte posterior enfrentados al frente. Hay una capa de barrera en la parte posterior del sustrato y una capa adhesiva superpuesta a la capa de barrera. La capa adhesiva comprende un primer componente polimérico, un segundo componente polimérico, siendo el primer componente polimérico un polímero no reticulado y siendo dicho segundo componente polimérico un polímero reticulado que presenta propiedades de superabsorbencia. El adhesivo presenta, cuando se expone al agua, una resistencia suficiente para unirse a un sustrato de pared y una resistencia al deslizamiento lo suficientemente baja como para permitir el reposicionamiento del revestimiento de pared deslizando el revestimiento de pared sobre la pared sin tener que levantarlo durante un período de tiempo de al menos menos 5 minutos.
