Problems solved by technology

Since the treatment of saline-alkali land, we have never stopped exploring the treatment of saline-alkali land, and have explored treatment technologies such as high water pressure alkali, salt washing by planting rice, open ditch for alkali removal, soil replacement for salt removal, and deep loosening blasting. High cost of treatment, lack of water resources, low land utilization rate and other issues have led to increased soil salinity, severe secondary salinization of some land, and the phenomenon of abandoned cultivated land
[0003] In a broad sense, salt discharge pipes are widely used, and can be used in saline-alkali land improvement, urban sewage discharge; discharge of chemical waste; transportation of substances with salt, alkaline properties, strong oxidizing properties, high temperature, etc. The quality, material, and structural strength of the salt pipe have put forward very high requirements; in the prior art, the structural strength of the pipe is difficult to meet the actual needs.

In the embodiment 1-5 of the invention, a raw material dicapryl phthalate of the hidden salt elimination tube containing polyethylene wax is mixed with absolute ethyl alcohol, and the mass ratio of dicapryl phthalate to absolute ethyl alcohol is 1:(4-5). The tensile breaking strength of the hidden salt elimination tube is 48-64 MPa; the tensile yield strength of the hidden salt elimination tube is 50-64 MPa; the breakage elongation of the hidden salt elimination tube is 188-217%.

Description

technical field [0001] The invention relates to a salt-discharging concealed pipe and a preparation method thereof, in particular to a salt-discharging concealed pipe containing polyethylene wax and a preparation method thereof. Background technique [0002] my country's saline-alkali land has a vast territory, and there are a lot of salt and alkali in the saline-alkali soil. The salinization of the land tortures the hard-working farmers and hinders the development of the economic society of the group farm. Since the treatment of saline-alkali land, we have never stopped exploring the treatment of saline-alkali land, and have explored treatment technologies such as high water pressure alkali, salt washing by planting rice, open ditch for alkali removal, soil replacement for salt removal, and deep loosening blasting. Problems such as high treatment costs, lack of water resources, and low land utilization rate have led to intensified soil salinization, severe secondary saliniz...
