Oil absorbing cotton

Abstract

The invention discloses oil absorbing cotton. The oil absorbing cotton comprises an oil absorbing layer and a hydrophilic oil-absorbing layer, the hydrophilic oil-absorbing layer is formed on the oil absorbing layer or wraps the oil absorbing layer, the oil absorbing layer is made of viscose and oil-absorbing polymeric fibers with a blending method, the hydrophilic oil-absorbing layer is made of a hydrophilic material and an oil absorbing material with a blending method, the viscose and the oil-absorbing polymeric fibers are blended in the ratio being 1:(1-3), and the hydrophilic material and the oil absorbing material are mixed in the ratio being (5-8):1. The oil absorbing cotton can easily absorb oil on a water surface, completely eliminate oil contamination and treat an oil leakage accident once for all, the oil absorbing layer and the hydrophilic oil-absorbing layer both adopt a porous structure, water and oil absorption can be guaranteed, and the water and oil absorbing rate can be increased.

Description

Technical field [0001] The invention relates to the field of oil-absorbing materials, in particular to an oil-flower absorbent cotton. Background technique [0002] When oil leaks on the sea surface, or when an oil leak from a factory pollutes the attached rivers, there are generally three methods to remove oil pollution. One is the dispersion method, which uses an oil dispersant to break the oil film to make it into particles and disperse into the water phase. In the middle, the oil dispersant accelerates the micronization process of the oil, spreads the oil in the vertical direction, and does not form an oil film on the surface of the water body, so that it does not adhere to ships, reefs and coastlines. The use of dispersants increases the surface area of ​​the oil and accelerates the biodegradation of the oil. However, dispersants are often more toxic. When the oil spill area is large, the efficiency of smelting oil is not high, and it is only suitable for the treatment of s...

Problems solved by technology

However, dispersants are often highly toxic, and when the oil spill area is large, the oil removal efficiency is not high, and it is only suitable for the treatment of oil spills on the sea surface

The second is the coagulation method, that is, the oil coagulant is used to rapidly increase the viscosity of the oil, so that the slick oil is formed into lumps, which is convenient for recovery. The coagulation method is not as common as the dispersion method, because the production process is complicated, the cost is high, and the recovery is difficult.

In the actual treatment of large-scale oil slicks, the use of such a high ratio of dispersants to oil spills results in a relatively high treatment price

Oil dispersants usually need to be sprayed by special devices such as ships and aircraft. Aircraft spraying is used to deal with large irregular oil films. The thickness of the oil film covering the sea surface is different. It is impossible for all the sprayed oil dispersants to meet the oil film, resulting in oil dispersant A large amount of waste of agent increases the processing cost
