Plastic blind ditch pipe core body and preparation method thereof
The invention provides a plastic blind ditch pipe core which comprises a first plastic net pipe, a second plastic net pipe and a third plastic net pipe which are formed by curling, entangling and bonding plastic tows, and the first plastic net pipe, the second plastic net pipe and the third plastic net pipe are sequentially stacked and sleeved from outside to inside. Pores in the first plastic net pipe, the second plastic net pipe and the third plastic net pipe are uniformly distributed; the first plastic net pipe is prepared from a hydrophobic material, the second plastic net pipe is prepared by mixing the hydrophobic material and a small amount of hydrophilic material, and the third plastic net pipe is prepared by mixing the hydrophobic material and a large amount of hydrophilic material; and liquid can rapidly permeate along the first plastic net pipe, the second plastic net pipe and the third plastic net pipe in sequence, so that the liquid can directionally flow in the third plastic net pipe. Liquid rapidly permeates through the wetting gradient effect, the liquid can be prevented from reversely seeping, it is guaranteed that the liquid directionally flows and is discharged along the third plastic net pipe, and the overall drainage efficiency of the plastic blind ditch pipe is improved.
本发明提供一种塑料盲沟管芯体，包括均由塑料丝束经卷曲、纠缠以及粘结所形成的第一塑料网管、第二塑料网管和第三塑料网管，第一塑料网管、第二塑料网管和第三塑料网管由外向内依次叠套；第一塑料网管、第二塑料网管和第三塑料网管上的孔隙分布均匀；第一塑料网管采用疏水性材料制备，第二塑料网管采用疏水性材料和少量亲水性材料混合制备，第三塑料网管采用疏水性材料和大量亲水性材料混合制备；液体可依次沿第一塑料网管、第二塑料网管和第三塑料网管快速渗入，使液体沿第三塑料网管内定向流动。本发明通过润湿梯度效应使液体快速渗入，并且能够阻隔液体无法反向渗出，保证液体沿着第三塑料网管内定向流动排除，增加塑料盲沟管整体的排水效率。
