Abstract

The invention relates to a salt drainage concealed conduit containing chitosan oligosaccharide. The salt drainage concealed conduit is characterized by being prepared from chitosan oligosaccharide. The invention further provides a preparation method of the salt drainage concealed conduit containing chitosan oligosaccharide. The preparation method is characterized by including a mixing step; according to the mixing step, the mixing temperature ranges from 220 DEG C to 223 DEG C, the mixing rotating speed ranges from 650 r / min to 670 r / min, and the mixing time ranges from 30 min to 40 min. The IZOD impact strength of the prepared salt drainage concealed conduit ranges from 18.1% to 21.2%; the elongation at break of the prepared salt drainage concealed conduit ranges from 218% to 235%; the tensile strength of the prepared salt drainage concealed conduit ranges from 237% to 253%; the heat deflection temperature of the prepared salt drainage concealed conduit ranges from 181 DEG C to 192 DEGC.

Description

Technical field [0001] The invention relates to a salt-discharging secret tube and a preparation method thereof, in particular to a salt-discharging secret tube containing chitosan oligosaccharide and a preparation method thereof. Background technique [0002] Landscaping construction in the coastal area has become an important part of the landscape engineering. Due to the high soil salinity in coastal areas, fewer types of seedlings suitable for planting, and low survival rate of seedling vegetation, how to ensure the survival rate of seedling vegetation has become a technical difficulty in landscaping projects. The most important link is to reduce the salt content of the soil required for planting seedling vegetation. [0003] The salt-discharging hidden pipe salt-discharging technology has obvious effects in discharging salt, transporting, and improving the soil. It can quickly drain the water in the soil, reduce the groundwater level, improve the soil structure, increase the s...
