Problems solved by technology

[0004] However, in the Qinghai-Tibet Plateau region in Northwest my country, due to its special geographical location, the temperature is low all year round, the humidity is low, and the temperature difference between day and night is large. Under low temperature conditions, it is difficult for vegetation to survive, especially for vegetation to take root and germinate.

preparation example 1

[0038] Using wet granulation method, firstly grind rice husk, perlite, horse dung and limestone into powder, then mix them evenly in a weight ratio of 2:1:0.3:0.1, add an appropriate amount of water or starch binder, and stir. Kneading, and then mechanically extruding through a 10-mesh sieve to obtain wet brewing hot particles, and then using fluidized bed drying method to dry and vibrate to remove moisture, prevent caking or deformation under pressure, and dry the dried granules. The fermented heat particles are passed through a 10-mesh screen again, and finally the fermented heat particles with a diameter of 2 mm are obtained.

preparation example 2

[0040]Using wet granulation method, firstly grind rice husk, perlite, horse dung and limestone into powder, then mix them evenly in a weight ratio of 2:1:0.3:0.1, add an appropriate amount of water or starch binder, and stir. Kneading, and then mechanically extruding it through a 2-mesh sieve to obtain wet brewing heat particles, and then using the fluidized bed drying method to dry and vibrate to remove moisture, prevent caking or deformation under pressure, and dry the dried granules. The fermented heat particles are passed through a 2-mesh screen again, and finally the fermented heat particles with a diameter of 8 mm are obtained.

[0041] Preparation of self-heating particles

preparation example 3

[0043] According to the weight ratio of 1:7:2:3, weigh salt, reduced iron powder, activated carbon and water, crush the activated carbon, add water to the reduced iron powder and activated carbon, stir and knead to make small granules; add to the salt Dissolve in water to form an electrolyte solution, under anaerobic conditions, disperse the small particles into the electrolyte solution, and stir at 50 ° C for 6 hours. During this process, add the electrolyte solution while stirring, and obtain the product after centrifugation. The diameter of the obtained self-heating particles ranges from 0.5 to 1.6 mm.

Abstract

The present application relates to the field of vegetation building materials, and specifically discloses a planting gypsum concrete spray and its application. The plant-based gypsum concrete spray is made from the following raw materials in parts by weight: 10-50 parts of gypsum, 50-80 parts of straw powder, 1-10 parts of grass seeds, 2-10 parts of vermiculite, 2.5-8.5 parts of water retention agent, surface active 0.5 to 3.5 parts of granules, 0.8 to 4.5 parts of rooting agent, 3.0 to 8.0 parts of wood flour, 1 to 10 parts of water-based adhesives, 1.5 to 3.5 parts of brewing heat particles and 1.8 to 2.5 parts of self-heating particles. The particles are agglomerated by solid electrolyte, reduced iron powder, activated carbon and water. The phytogenic gypsum concrete spraying material of the present application is mixed with water and then sprayed on bare ground or the edges of roads, rivers and lakes in alpine regions.

Description

technical field [0001] The present application relates to the field of vegetation building materials, more particularly, it relates to a plant gypsum concrete spray and its application. Background technique [0002] With the improvement of people's living standards and the enhancement of environmental protection awareness, people's requirements for the quality of the living environment are getting higher and higher. Planting lawns on bare ground in cities is one of the important measures to beautify the environment, purify the air, and preserve soil and water; the traditional technology mainly adopts the seed propagation method, but the labor is expensive, the maintenance and management workload is large, and the grass grows slowly. Artificial soil for growing grass seeds. In addition, my country often forms a large number of exposed slopes in construction projects such as transportation, mining, electricity and water conservancy, causing vegetation damage, soil erosion, an...
