Partition wall slats prepared by wind and sand and its preparation method

Abstract

The invention relates to a partition wall slat, in particular to a partition wall slat prepared by wind-blown sand and a preparation method thereof. Made of raw materials including the following percentages by weight: wind sand 40%-65%, light aggregate 15%-30%, aggregate 10%-20% and admixture 5%-20%; the admixture includes the following components by weight : 40-50 parts of silicate, 1-5 parts of borate, 2-10 parts of sulfate, 3-5 parts of phosphate, 3-5 parts of hydroxide, 1-3 parts of halogen salt and lignosulfonic acid 1‑5 parts of salt. The chemical modification of particle surface, the combination of intergranular substances, the formation of gel substance and the formation of crystal structure of sand and light aggregates occurred under the action of admixture. The quality of the prepared partition wall slats is stable, has the characteristics of high bending load self-weight multiple, high compressive strength, high softening coefficient, etc., and has excellent functions such as light weight, heat preservation, high strength, fire prevention, and waterproof; the invention also provides its The preparation method is low in cost and environment-friendly.

Description

technical field [0001] The invention relates to a partition wall slat, in particular to a partition wall slat prepared by wind-blown sand and a preparation method thereof. Background technique [0002] Desert wind and sandstorms deteriorate the ecological environment, destroy living conditions, aggravate natural disasters, restrict economic development, deepen poverty, seriously affect social stability, and cause great harm to my country's national economy and social development. According to estimates, the direct economic loss caused by land desertification in my country reaches 54 billion yuan every year, and desertification also threatens large and medium-sized cities, transportation, water conservancy facilities, and industrial and mining enterprises. At present, there are more than 1,300 kilometers of railways, 30,000 kilometers of roads, thousands of reservoirs and more than 50,000 kilometers of irrigation canals in the country that are always affected by wind and sand...

AI Technical Summary

Problems solved by technology

[0004] The domestic use of desert wind and sand mainly has the following problems: (1) The particle size of desert wind and sand is small, and comprehensive utilization is difficult

(2) The value of wind and sand itself is not high, and it is too far away from the place where there is demand, the cost of transportation is too high, and it is difficult to use

[0005] At present, there are no related patents and reports on the use of desert wind and sand to prepare partition wall slats
