The process for micro foaming of the assembly type building light wallboard has the advantages that the light materials such as the ceramsite and the cocoanut cellulose are adopted and prepared into the light wallboard high in combination property together with the ordinary Portland cement, the coal cinder, the fly ash and other auxiliaries according to a certain proportion.

Disclosed herein is a process for preparation of a secondary battery module. The process includes forming coupling through-holes having specific shapes at plate-shaped electrode terminals of a plurality of unit cells, stacking the unit cells one on another, and inserting coupling members through the coupling through-holes to couple the unit cells with each other. Consequently, the secure coupling and the electrical connection between the unit cells is accomplished without using additional members, such as cartridges, and therefore, a compact battery module having high coupling force is prepared.

The invention belongs to the technical field of biomedical dressings and relates to an end-capped modified polyethylene glycol cross-linking agent having an ultraviolet light response function, a preparation method and a hydrogel dressing containing the cross-linking agent and a preparation method thereof. The technical problem is solved that wound pain and secondary wounds care caused by when anexisting hydrogel dressing is removed for secondary wound treatment. The modified polyethylene glycol cross-linking agent having the ultraviolet light response function is formed by adopting an injectable in-site gel forming mode, and the gel forming mode has very good adaptability to wound shapes and meanwhile has better fitting property compared with a blocky dressing to be gelled without auxiliary fixing materials. When wounds need to be further treated, regional selective irradiation can be performed through 10 mw / cm<2> ultraviolet light of 365 nm, gel softening and degradation are achieved. Compared with other dressings, the function can prevent wound pain during gel removal and prevent newly growing tissues from being physically harmed to cause secondary wounds.
