The invention discloses a preparation process of a double-sided sinusoidal modulation polymer film. The preparation process comprises the following steps: preparing a red copper template; preparing a silicone rubber soft template by using the red copper template; preparing a hard transparent high-temperature-resistant epoxy resin hard template by utilizing the silicon rubber soft template; preparing a preformed polymer film; dividing the epoxy resin hard template into an upper template and a lower template, placing the preformed polymer film between the upper template and the lower template, and using a microscope to assist the upper template, the lower template and the preformed polymer film to align and fix; and copying patterns on the preformed polymer film through vacuum hot pressing, namely copying the patterns on the upper template and the lower template to two surfaces of the preformed polymer film respectively to obtain the double-sided sinusoidal modulation polymer film. The double-sided ...

Anti-shaking sampling device and sampling method for geological coal mine exploration

Номер: CN116067696A
Автор: LI WA, WANG ZHIHUI
Принадлежит:

The invention relates to the field of soil sampling, in particular to an anti-shaking sampling device for geological coal mine investigation, which comprises a drill bit, a support column coaxially connected with the drill bit is arranged on the drill bit, a grip is arranged at the top end of the support column, and a sampling mechanism for driving the drill bit to screw in and taking out sampled substances is further arranged at the joint of the drill bit and the support column. The device further comprises an anti-shaking supporting mechanism, the anti-shaking supporting mechanism is provided with a ground supporting assembly and an abutting assembly, the ground supporting assembly is arranged on the supporting column, and the abutting assembly is arranged between the supporting column and the ground supporting assembly. When the drill bit gradually goes deep into the soil, the abutting assembly is triggered to apply pressure to the ground supporting assembly, so that the ground supporting ...
