Preparation method of fiber additive for concrete and mortar

Abstract

The invention provides a preparation method of a fiber additive for concrete and mortar. A storage frame, a control device, a connecting cylinder, a pressing device and a support are matched to complete operation. The preparation method of the fiber additive for concrete and mortar can solve the problems that in the fiber additive processing process, a prepared fiber additive needs to be conveyedto the edge of a packaging bag through a conveying belt, then the fiber additive is placed into a bag in a push-in mode, due to the fact that short fiber filaments are prone to expanding, it is difficult to put in a large amount of short fiber filaments when the short fiber filaments are pushed into the bag, a person usually pushes the short fiber filaments while pressing the short fiber filamentsmanually so as to guarantee that the amount of the short fiber filaments placed in the bag is larger, but only a part of the short fiber filaments are pressed down in the manual pressing mode, an effective press-down area is difficult to form, and the working efficiency is difficult to improve by a manual push-in and press-down mode.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing fiber additives for concrete and mortar. Background technique [0002] Fiber additive for concrete mortar belongs to a kind of building material. It is a kind of high-strength bundled monofilament organic fiber formed by special processing. Its strength directly affects its use effect in concrete. Generally, the stronger the strength The larger the size, the more ideal the use effect can be. Mixing fiber additives into the concrete can greatly enhance the flexibility and crack resistance of the concrete. [0003] During the processing of fiber additives, the prepared fiber additives need to be transported to the edge of the packaging bag through the conveyor belt, and then put into the bag by pushing. It is difficult to put a large amount into the bag, and the personnel usually press it manually while pushing it in to ensure that the amount of s...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a method for preparing fiber additives for concrete and mortar, which can solve the problem of transporting the prepared fiber additives to the edge of the packaging bag through a conveyor belt during the processing of fiber additives, and then pass Put it into the bag by pushing it in. Because the fiber short filaments are easy to expand, it is difficult to push it into the bag to fill a large amount. The personnel usually press it manually while pushing it in to ensure that the fiber short filaments placed in the bag are short. The amount of silk is more, but this manual pressing method only presses down a part of the short fiber filaments, it is difficult to form an effective pressing area, and the manual pushing and pressing method is difficult to improve work efficiency and other problems
