Embodiment Construction

[0011] Examples are given below: in order to prepare 250 kilograms of wind-blown sand curing polymerization agent finished products. Such as figure 1 As shown, under normal temperature and pressure, dissolve 60 kg of magnesium chloride with 125 kg of water to make liquid A; fully mix 2.5 kg of formaldehyde, 60 kg of urea, and 1 kg of sodium hydroxide to make liquid B; age 5 hours. Put the two solutions of A and B into a miscible, mix them and then fully stir them to obtain the wind-sand solidification polymerization agent. When in use, mix 250 kg of this wind-blown sand solidifying polymer with 3,000 kg of wind-blown sand and 350 kg of magnesium oxide, then add a certain amount of glass fiber filaments (other fiber filaments are also available), and use a 350-type mixer to stir evenly. Then use the HXQT4WS-20 block forming machine to load the blocks, vibrate, compact and finally form them. The compressive strength is 28.5MPa, the flexural strength is 6.6MPa, the compressive...

Abstract

The invention discloses a preparation method of wind sand solidification paver bricks, comprising: at normal temperature and normal pressure, dissolving magnesium chloride with water to prepare A liquid; fully dissolving formaldehyde, urea and sodium hydroxide to prepare B liquid; mixing and fully stirring above two solutions to obtain a wind sand solidification polymerizer; then, evenly mixing and stirring the wind sand solidification polymerizer, magnesium oxide and aeolian sand, and feeding to a building block shaping machine; and preparing the wind sand solidification paver bricks by shaking, ramming and shaping. The preparation method has simple technology, the main raw material of manufactured building bricks is aeolian sand, which authentically realizes that sand is changed into valuables and provides a new path for radical treatment of desert. When manufacturing building bricks, the preparation method of the invention can save a great quantity of coal, natural gas and water, has low cost, is easy to popularize and has wide application prospect.

Description

technical field [0001] The invention relates to a method for preparing bricks, in particular to a method for preparing pavement bricks solidified by wind and sand. Background technique [0002] Aeolian sand is also called aeolian sand. my country has 1.74 million square kilometers of desertified land, of which the real treatable area is about 500,000 square kilometers, and 1.2 million square kilometers are untreatable native deserts. Sand prevention and control have become the long-term struggle direction of human beings, and how to use deserts to benefit human beings is an ideal goal pursued by people. The "sand industry" that has emerged in recent years is a concrete action to achieve the above goals. At present, the production of ceramic bricks and cement requires a large amount of natural gas, coal and other resources to complete the sintering process. For example, if the calculation is based on the production of 10 square meters of ceramic tiles, the energy cost is 5...
