A method for recycling iron ions and preparing FePO₄ is provided. The method includes: (a) providing an iron ion-containing solution; (b) passing the iron ion-containing solution through a chelating cation exchange resin to obtain an ion-adsorbed resin and a first eluate; (c) desorbing ferric ions from the ion-adsorbed resin using a phosphoric acid solution with a concentration ranging from 10 wt% to 45 wt%, producing an ion-desorbed resin and a second eluate; and (d) heating the second eluate to produce a third solution containing an FePO₄ precipitate. This method efficiently recycles iron ions, prepares FePO₄ with minimal waste, and reduces overall costs.

An injection physical foaming inner boot (100, 200, 300) includes a shaft portion (20) and a foot portion (10) including a forefoot section (11) and a hindfoot section (12). A hardness of the forefoot section (11) is greater than a hardness of the hindfoot section (12). The shaft portion (20) extends upwards from the hindfoot section (12) of the foot portion (10). The foot portion (10) and the shaft portion (20) are integrally formed. Both the foot portion (10) and the shaft portion (20) include a thermoplastic material and do not include a crosslinking agent and a chemical foaming agent. Both a specific gravity of the foot portion (10) and a specific gravity of the shaft portion (20) are 0.1∼0.3g/cm<3>. The hardness of the forefoot section (11) is greater than a hardness of the shaft portion (20). A method of manufacturing an inner boot by injection physical foaming is provided.

A co-molded shoe component (100, 100A) and a method of manufacturing the same are provided. The co-molded shoe component (100, 100A) includes an outsole (10, 40) and a midsole (20). A side of the outsole (10, 40) has a plurality of anchor structures. The anchor structures could be protrusions (13, 13A, 13B, 13C, 13D), recesses (14), or through holes (15, 16). The midsole (20) is formed through physical foaming with a supercritical fluid and is simultaneously engaged with the outsole (10, 40). A part of the midsole (20) is completely engaged with the anchor structures. The method includes placing the formed outsole (10, 40) in a mold (300), controlling an air pressure in the mold (300), and after injecting a thermoplastic foaming fluid, releasing the air pressure to foam the thermoplastic foaming fluid to form the midsole (20) and to integrally engage the midsole (20) with the outsole (10, 40).

The invention relates to a support system for supporting a facade element relative to a wall, wherein the support system comprises a facade support for supporting the facade element in a support plane and one or more consoles for mounting the facade support relative to the wall,wherein the facade support is substantially Z-shaped and comprises a central part, and a support flange and a seating flange that project away from the central part at opposite sides of the central part,wherein the facade support is provided with a plurality of receiving slots that extend through the seating flange, wherein each of the one or more consoles comprises one or more hooks that protrude in a direction normal to the seating plane, and wherein each hook is arranged to be received in a respective one of the receiving slots for retaining the seating flange in the projection direction.

A high-adhesion composition comprises: a thermoplastic material; and a cross-linked rubber; wherein the high-adhesion composition has a toluene insoluble content equal to or higher than 10%.
