Embodiment Construction
[0042] The present invention will be described below in conjunction with specific embodiments.
[0043] Such as Figure 1 to Figure 5 As shown, a neutron-absorbing laminate manufacturing process with a large-radius end face angle of 135 degrees includes the following process steps, specifically:
[0044] a. Select an aluminum plate 1 with a thickness of 1mm and send the aluminum plate 1 to the shearing machine for cutting and cutting. The aluminum plate 1 cut by the shearing machine is rectangular;
[0045] b. Grinding the filler contact surface of the cut aluminum plate 1 with a grinding wheel grinder so that the filler contact surface of the aluminum plate 1 becomes rough, and the roughness of the filler contact surface after grinding is 12.5 μm;
[0046] c. Send the polished aluminum plate 1 into a CNC bending machine for bending treatment. The aluminum plate 1 after being bent by the CNC bending machine includes an arc-shaped base 11 curved in a circular arc shape, and the ...

Abstract
The invention discloses a manufacturing technique for a neutron absorbing laminate with a large-radius end face angle at 135 degrees. The manufacturing technique comprises the following steps: (a) cutting an aluminum plate; (b) polishing a padding contact surface of the aluminum plate; (c) bending the aluminum plate; (d) preparing an absorbing laminating mold; (e) arranging the absorbing laminating mold on a 80T four-column hydraulic press; (f) cleaning with alcohol; (g) uniformly attaching a teflon protecting film on an arc-shaped forming surface of an upper forming mold; (h) coating vaseline; (i) putting the aluminum plate into a lower forming tank and then coating with glue; (j) putting the boron carbide padding into the lower forming tank and then pre-pressing a stainless steel roller; (k) closing the mold and maintaining pressure; (l) statically solidifying; and (m) de-molding and completing the preparation of the neutron absorbing laminate. Through the technical steps, the arc-shaped neutron absorbing laminate can be effectively produced and prepared. The manufacturing technique provided by the invention is effectively suitable for the production processing of a large-radius neutron absorbing device.
Description
technical field [0001] The invention relates to the technical field of neutron absorbing devices, in particular to a manufacturing process of a neutron absorbing laminate with a large-radius end face angle of 135 degrees. Background technique [0002] In nuclear devices, in order to prevent nuclear radiation, neutron materials and technologies are often used for shielding protection; currently commonly used neutron absorbing materials are lead-boron polyethylene and boron-containing polypropylene, which have the advantages of simple shielding structure and low weight Light and small in size; however, lead-boron polyethylene is easy to age and has a short life, which limits its application; cadmium plates can also be used as neutron absorbing materials, but cadmium is toxic and carcinogenic; boron steel can also be used as neutron absorbing materials, However, the boron content of boron steel is too low to meet the shielding requirements. [0003] Further explanation is requ...
