Furthermore, the design of the crushing assembly effectively improves the grinding efficiency of the grinding equipment.

The application relates to the technical field of coil coating, and discloses a radiation refrigeration coil coating composition, a coating and application, the coating composition comprises a basecoat composition and a topcoat composition which are arranged independently. The basecoat composition comprises polyvinylidene fluoride resin slurry, hydroxy acrylic resin, heat-reflecting filler and blocked polyisocyanate curing agent; the topcoat composition comprises polyvinylidene fluoride resin slurry, hydroxy acrylic resin, heat-emitting filler and topcoat crosslinking agent. The application sets the unblocking starting temperature of the basecoat curing agent to be lower than the starting temperature of the topcoat crosslinking reaction, realizes gradient crosslinking of a multilayer coating film from bottom to top, and solves the exhaust blistering defect during baking of a thick coating film. The glass transition temperature of the multilayer coating body is controlled to be 35 DEG C to 50 DEG C, the deformation requirement of warm stamping processing is met, and the coating film is prevented from cracking.

The invention relates to the technical field of water body sampling, and discloses a water body stratified sampling device for water quality detection, the water body stratified sampling device comprises a support column, the top of the support column is fixedly connected with a fixing ring, one end, far away from the support column, of the fixing ring is fixedly connected with a shell, and the outer wall of the shell is fixedly connected with a fixing block; the fixing block is fixedly connected with the fixing ring, the end, away from the fixing ring, of the supporting column is rotationally connected with a fixing assembly, a telescopic rod is arranged in the shell and fixedly connected with the top of the shell, and the bottom of the telescopic rod is fixedly connected with a fixing rod. The end, away from the telescopic rod, of the fixing rod is fixedly connected with a connecting rope, and the end, away from the fixing rod, of the connecting rope is fixedly connected with a traction ball, so that water bodies with three different depths can be sampled at the same time, the working efficiency of equipment is improved, the impact resistance of the sampling pipe is improved, and the sampling pipe is prevented from inclining in the sampling process; the sampling precision is improved.

The application discloses a winding and tensioning equipment for production and processing of scientific veneer, which comprises a traction part, the traction part comprises a machine base, the machine base is rotationally connected with a traction stick through a frame arranged on the top of the machine base, and a winding part, the winding part comprises a rotating stick, the rotating stick is fixedly connected with a rotating shaft through a limiting plate arranged on the outer end of the rotating stick, and the application relates to the technical field of scientific veneer winding. The winding and tensioning equipment for production and processing of scientific veneer can effectively solve the problem that tension adjustment is a very critical step when veneer is wound in the prior art, proper tension can ensure the flatness and curling degree of the veneer, and can avoid wrinkles or loose phenomenon, and general common winding equipment does not have an independent tensioning structure, and can only control the rotating speed of a winding roller motor or a frequency converter to control the winding tension, and thus cannot maintain stable rotating speed, thereby reducing the problems of veneer roll neatness and tightness.
