A water-absorbing agent according to the present invention includes water-absorbent resin particles having an internal cross-linked structure, wherein a vicinity of a surface of the water-absorbent resin particle is cross-linked with a surface cross-linking agent, and the water-absorbent resin particle has therein a sea-island structure having (i) part containing a first water-soluble multivalent metal salt such as aluminum sulfate and (ii) part not containing the first water-soluble multivalent metal salt. With this arrangement, it is possible to provide a water-absorbing agent having less water-soluble component content, more excellent liquid permeability, and more excellent water retention under pressure than the conventional water-absorbing agent.

The invention belongs to the technical field of clamping and pressing type pipe fittings, in particular to a thick-wall clamping and pressing type pipe fitting. The thick-wall clamping and pressing type pipe fitting comprises a thick-wall pipe fitting body arranged between two thick-wall steel pipe bodies and used for being connected with the thick-wall steel pipe bodies, and a sealing ring used for sealing, a positioning check ring and a gear ring are installed between the thick-wall pipe fitting body and the thick-wall steel pipe bodies; the thick-wall pipe fitting body comprises a connecting section located in the middle, a first flaring section and a second flaring section, wherein the first flaring section and the second flaring section expand and extend towards the two sides; a thick-wall metal pipe design is adopted, a special tool is used for crimping to deform the pipe fitting, so that the pipe fitting and a steel pipe are connected instantaneously, a crimping tool crimps a socket section of the pipe fitting, the socket section is provided with the sealing ring and the high-strength gear ring, and the sealing ring and the high-strength gear ring are compressed at the sametime to force the sealing ring in a socket section groove to cling to the steel pipe to achieve sealing and water-stopping operation; and the high-strength gear ring shrinks to firmly fasten the steelpipe, so that a good tensile effect is achieved. Due to the adoption of the thick-wall design, and good pressure-bearing performance and impact resistance are achieved.
