Embodiment

[0019] Embodiment: A kind of method of producing light-weight partition wall slats with industrial slag and construction waste recycling of this example, its steps are as follows figure 1 ,for:

[0020] a. The industrial slag is screened, and the fine material with a particle size of less than 5 mm is selected as the raw material for industrial slag regeneration, which is sent to the first silo through the material conveyor; after screening and separation, the industrial slag over 5 mm is transported to the crusher through the material conveyor After crushing, the crushed industrial slag particles below 5 mm are sent to the first silo through the material conveyor as recycled industrial slag particles for use. The material conveyor is equipped with an iron removal device to absorb the metal substances contained in the industrial slag. clear;

[0021] b. The construction waste is sorted, and then the first coarse crushing is carried out. The coarsely crushed construction was...

Abstract

The invention relates to a method for producing lightweight partition batten, and especially relates to a method for producing lightweight partition batten by recycling industrial slag and building garbage. The technical problem that a part of raw material employs large particles with more than 5mm in a partition batten production method in the prior art, so that agglomeration is easy, water absorption is poor, drying shrinkage value and creep value are less, cracking-resistant performance and extensibility are poor, crack is easily generated during the processing process can be solved. According to the invention, industrial slag and building garbage are sorted and screened, the fine stuff with particle size of less than 5 millimeters is taken as a regenerative raw material, industrial slag regenerative particles, building garbage regenerative particles, industrial waste sands, and ceramsite are placed in a mixer for mixing and stirring, cement and fly ash with certain mass percentage are placed in order for secondary mixing and stirring, water is added after second fully mixing and stirring for third stirring, and a mixture for producing the lightweight partition batten can be finally obtained.

Description

technical field [0001] The invention relates to a method for manufacturing a lightweight partition wall strip, in particular to a method for producing a lightweight partition wall strip by recycling industrial slag and construction waste. Background technique [0002] With the transformation of my country's building materials industry and the country's emphasis on environmental protection, future building materials will be green and ecological building materials with low pollution, low energy consumption, and renewable characteristics, and the new environmentally friendly lightweight partition board is one of the best kind of. The so-called lightweight partition wall panels refer to building wall panels with light and thin components (thickness is generally 90mm and 120mm), low apparent density, non-load-bearing, good heat insulation, sound insulation, and fire prevention effects. According to the characteristics of recycled concrete, it can be used to prepare new lightweigh...
