The utility model discloses a UV pressing and curing device applied to BC battery pieces and a series connection machine. The UV pressing and curing device comprises a lifting assembly. The welding lamp assembly is movably arranged on the lifting assembly, the lifting assembly drives the welding lamp assembly to do linear lifting motion in the longitudinal direction, and the welding lamp assembly can do transverse linear motion relative to the lifting assembly; and the pressing needle assembly is fixedly arranged below the welding lamp assembly, and the pressing needle assembly is used for carrying out flexible pressing operation on the welding strip arranged on the curing area. The welding lamp assembly and the pressing needle assembly are sequentially driven by the lifting assembly to move downwards, so that a welding strip on a BC battery piece is flattened and tightly attached to a BC battery piece grid line, and the problem of head warping or insufficient welding and missing welding in the solidification and series connection process of an existing BC battery piece and the welding strip is effectively solved.

The application discloses a recyclable blow molding grade thermoplastic polyester elastomer and a preparation method thereof, which is prepared from the following components according to weight parts: thermoplastic polyester elastomer 92-99 parts, isocyanate chain extender 1-3 parts, difunctional epoxy resin 0.8-2.4 parts, and antioxidant 0.1-0.8%. In the blow molding process, the chain extender dimer and the epoxy group become the source of chain extension slow release, part of the dimer decomposes into monomers, and the monomers are chain-extended again, and meanwhile the remaining epoxy groups also participate in chain extension. The loss of chain scission degradation at high temperature is made up, the melt index and other performance changes are still small, and 100% secondary material is independently used. Through 5 times of double screw extrusion test, the melt index of the thermoplastic polyester elastomer changes very little, which provides reliable guarantee for the separate multiple recycling of the blow molding grade thermoplastic polyester elastomer in the factory.

This invention discloses a power amplifier with partial modulation, relating to the field of wireless communication technology. It includes a Doherty power amplifier for partial modulation and a balanced power amplifier for global modulation. The Doherty power amplifier for partial modulation includes an RF signal input terminal, a power divider, sub-amplifiers D3 and D4, and a load modulation network. The RF signal input terminal inputs the RF signal to sub-amplifiers D3 and D4 through the power divider, and after amplification by the sub-amplifiers, it is synthesized by the load modulation network. The balanced power amplifier includes an RF signal input terminal, an input coupler, sub-amplifiers D1 and D2, and an output coupler. The output of the Doherty power amplifier is connected to the isolation port of the balanced power amplifier's output coupler. This invention achieves an extended dynamic range, solves the main path oversaturation phenomenon in timing modulation power amplifiers, establishes a systematic and complete technical foundation for the design of broadband large dynamic load modulation power amplifiers, and expands the application scenarios of wireless communication networks.

The invention discloses fiber polymer titanium gypsum mortar and a preparation method thereof. The fiber polymer titanium gypsum mortar is prepared from the following raw materials in parts by weight: 40 to 60 parts of titanium gypsum, 40 to 60 parts of sand, 10 to 15 parts of alkaline additive, 0.5 to 1 part of sodium sulfate, 2 to 3 parts of quick lime, 0.1 to 3 parts of plant fiber, 1 to 2 parts of cellulose ether, 0.2 to 2 parts of water reducing agent, 1 to 5 parts of redispersible latex powder and 0.1 to 2 parts of retarder. The doped plant fiber raw material is wide in source, so that the impermeability and the crack resistance of the gypsum mortar are effectively improved, and meanwhile, the construction performance is improved. The titanium gypsum is only dried and does not need to be calcined, certain additives and plant fibers are added, the high-water-resistance gypsum mortar with the titanium gypsum as a main cementing material is obtained, an energy-saving and environment-friendly product with good mechanical properties is provided, and meanwhile the high-water-resistance gypsum mortar has the advantages of being low in production cost, wide in raw material source and good in water resistance.
