Problems solved by technology

[0002] Nano-calcium carbonate can improve the rheology of plastic masterbatch and improve its formability. It can be used as a plastic filler to enhance toughness and reinforcement, improve the bending strength and bending elastic modulus, heat distortion temperature and dimensional stability of plastics, and at the same time It endows plastic with thermal hysteresis, so it is widely used in industrial production. In the production of nano-calcium carbonate, continuous spray carbonization is used for production, but the current spray tower cannot change the size of spray particles according to needs, thus making the equipment applicable. Low

Abstract

The invention discloses a continuous spraying carbonization process of nano calcium carbonate for polypropylene, and relates to the related field of nano calcium carbonate, the continuous spraying carbonization process comprises a spraying tower, a spraying tower cover is slidably arranged on the spraying tower, five fixing bolts are arranged between the spraying tower cover and the spraying tower in a threaded mode, and an auxiliary mechanism is arranged on the spraying tower cover. A reaction space is arranged in the spray tower, a stirring mechanism is arranged in the reaction space, a spray plate is fixedly arranged in the spray tower cover, a continuous injection mechanism is arranged in the spray plate, a switching mechanism is arranged in the spray tower cover, CO2 gas with the volume concentration of 22%-31% is introduced into the spray tower, the gas concentration is sequentially increased from top to bottom, and the CO2 gas with the volume concentration of 22%-31% is introduced into the spray tower. And an annular rack plate is rotated, so that an annular rack rotates, an iris mechanism rotates, the spraying hole diameter of the iris mechanism is adjusted, the diameter of a sprayed material can be adjusted according to requirements, and the applicability of the equipment is greatly improved.

Description

technical field [0001] The invention relates to the related field of nano-calcium carbonate, in particular to a continuous spray carbonization process of nano-calcium carbonate for polypropylene. Background technique [0002] Nano-calcium carbonate can improve the rheology of plastic masterbatch and improve its formability. It can be used as a plastic filler to toughen and reinforce, improve the bending strength and bending elastic modulus, heat distortion temperature and dimensional stability of plastics, and at the same time It endows plastic with thermal hysteresis, so it is widely used in industrial production. In the production of nano-calcium carbonate, continuous spray carbonization is used for production, but the current spray tower cannot change the size of spray particles according to needs, thus making the equipment applicable. Low. Contents of the invention [0003] The object of the present invention is to provide a kind of continuous injection carbonization ...
