The invention relates to a mica tape manufacturing method with low production cost. With the method, environment pollution is reduced. The method is suitable for energy saving and emission reduction. The method comprises the steps that: a nano-grade material processed through a surface activation treatment is added to mica powder; the nano-grade material and the mica powder are subject to high-speed stirring dispersion, and an obtained uniformly-mixed material is preserved for later use; a first adhesive is coated on a reinforcing material by using a roller; with an electrostatic field, the mica raw material is absorbed onto the reinforcing material; a second adhesive is sprayed onto the mica raw material of the reinforcing material; the one-side reinforced mica tape half-finished product is delivered through a baking oven, such that an organic solvent is removed by baking; the product is cooled, and is rolled and coiled by using a roller, such that a one-side reinforced mica tape finished product is obtained. The invention relates to a novel production technology designed according to natural characteristics of electric charges. Only a small amount of the solvent is required, such that the production cost of the mica tape is reduced, and environment pollution caused by the organic solvent is greatly reduced. Also, production speed can be improved, and baking temperature can be reduced, such that electric energy consumption can be reduced by approximately 1 / 3.

The invention provides a composite fiber reinforced polymer (FRP) rebar preparation device which comprises a yarn feeding device, an impregnation device, a forming device, a heating curing device, a traction device, a cutting device and a length control device. Relative to the prior art, the preparation device has substantive characteristics and progress, particularly, yarn pressing rolling shafts and yarn threading holes are arranged in the yarn feeding device of the composite FRP rebar preparation device, so that fiber bundles are enabled to be in a tension state, and different fiber bundles are prevented from knotting and rubbing; through the adoption of the impregnation device, the fiber bundles are fully and uniformly impregnated, the coating amount is small, the fiber content of a composite FRP rebar is increased, and the standard deviation of the mechanical performance of the composite FRP rebar is reduced; through the adoption of the forming device, the distribution uniformity of the fiber bundles in thermosetting resin is greatly improved; through the adoption of the heating curing device, the curing temperature is enabled to be stable, and the production is facilitated; and through the adoption of a buzzer of the length control device, operators can be reminded to carry out cutting, the FRP rebar is prevented from being over-roasted, and the continuity and safety of production are improved.

The invention relates to a screw type dipping equipment, comprising a dipping sleeve, a dipping shaft fitted inside the dipping sleeve, a glue injection port, a tow inlet and a tow outlet arranged on the same side of the dipping sleeve , the tow inlet and tow outlet are respectively located at the left and right ends of the dipping sleeve. The dipping shaft is a screw type dipping shaft, and the thread length of the dipping shaft is less than the length of the dipping sleeve. The glue is poured from the glue injection port, and the size of the tow inlet and tow outlet can be adjusted by adjusting the block and fastening bolts. By adjusting the size of the tow inlet to ensure that the tow entering the dipping sleeve is neat Generally, the glue content of the fibers coming out of the dipping sleeve after dipping is controlled by adjusting the size of the tow outlet.
