Embodiment Construction

[0012] Afterwards, the production method of the air-permeable anti-seepage sand according to the present invention will be described in detail.

[0013] Materials and proportions used in the production of air-permeable anti-seepage sand: 98 parts by weight of sand; 0.5 parts by weight of silane coupling agent; 1.5 parts by weight of stearic acid, that is, the proportion of sand, silane coupling agent and stearic acid is sand : silane coupling agent: stearic acid = 98:0.5:1.5.

[0014] The equipment required for the production of the air-permeable anti-seepage sand includes: a drying furnace, a spiral feeding hoist, a cone powder mixer and quantitative filling equipment.

[0015] The production method of air-permeable anti-seepage sand comprises the following steps:

[0016] Step (1), drying the sand in a certain number of parts by weight in a drying furnace, so that the moisture in the sand is lower than three thousandths;

[0017] Step (2), sand is poured out from drying ov...

Abstract

The invention discloses a production method for air-permeable impermeable sands. The production method comprises the following steps of step (1), drying the certain weight parts of sands in a drying furnace so that the moisture of the sands is lower than 3 per thousand; step (2), pouring out the sands from the drying furnace; step (3), after the sands are naturally cooled down at about 70 degree centigrade, lifting the sands into a conic powder mixing machine by utilizing a spiral material-feeding lifting machine, simultaneously adding silane coupling agents with corresponding weight parts to the conical powder mixing machine while lifting the sands, and fully stirring for 20-25 minutes; step (4), adding stearic acid with corresponding weight parts and continuously stirring for 20-25 minutes, wherein the proportion of the weight parts of the sands, the silane coupling agents and the stearic acid in the steps (1), (3) and (4) is 98:0.5:1.5; step (5), filling by utilizing a quantitative filling device to obtain the finished product after the step (4) is finished.

Description

technical field [0001] The invention relates to a production method of air-permeable and anti-seepage sand. Background technique [0002] China is a country seriously short of water. More than half of the land has an average annual rainfall of less than 600 millimeters, and the per capita water resources are less than a quarter of the global average. Especially in the central and western regions, the climate is dry and the rainfall is low. It is also plagued by water shortages, which seriously restricts the development of the local economy. At the same time, the waste of water resources in my country is very serious. In a similar geographical environment, the water consumption per mu of crops in my country is nearly twice that of developed countries. The traditional flood irrigation method consumes even more water. 70% of the irrigation water is wasted due to outdated irrigation methods seeping into the ground. For example: during the seedling growth period of the same Pin...
