A process for treating a substrate made of stone material, preferably in the form of slabs, is provided which process improves the mechanical, thermal and catalytic properties of the substrate. The process includes applying a protective coating to the outer surface of the substrate made of stone material and, to improve adhesion of the protective coating to the outer surface of the substrate, preliminarily subjecting the substrate to one or more pre-treatment steps that eliminate or reduce the presence of pollutants and porosity on the surface of the substrate. The pre-treatment of the substrate made of stone material comprises at least one step of treatment under vacuum conditions inside an autoclave, preferably under pressure conditions lower than 10.sup.2 mbar. Then, after having brought the substrate back to ambient pressure, it is possible to apply and effectively adhere the protective coating to the surface of the stone material.

The present invention provides a method for preparing an artificial glass surface, which includes the following steps: step A: mixing a glass material and a silane coupling agent to obtain an initial glass material mixture. Step B: heating a silicone resin, mixing with the initial glass material mixture thoroughly to obtain a secondary glass material wrapper. Step C: adding an unsaturated polyester resin, a curing agent, a filler pigment, and a quartz material to obtain a glass surface premade material. Step D: pressing the glass surface premade material, curing to obtain the artificial glass surface. In this invention, the quality of the product is maintained at a high level, mineral resources are conserved, and production cost is lowered.

An adsorption structure unit prevents water leakage from an adsorption structure and improves the durability of the adsorption structure and the durability of the adsorption structure unit. An adsorption structure has a filter portion having a plurality of flow paths divided by a plurality of partition walls and a plugged portion shutting a feed water inflow or outflow end of the plurality of flow paths, a water-impermeable outer tube accommodating the filter portion, and a seal material blocking a gap between the filter portion and the outer tube in at least one end portion of the filter portion. An adsorption structure unit has the adsorption structure, a housing supplying feed water from one end of the adsorption structure, and discharging the feed water from the other end, and a ring member disposed between end portions on both sides of the outer tube and an inner surface of the housing.
