Embodiment Construction

[0012] The present invention is not limited by the following examples, and the specific implementation manner can be determined according to the above-mentioned technical solutions and actual conditions of the present invention.

[0013] The composite geomembrane among the present invention can adopt the composite geomembrane that meets national standard GB / T17642-1998, according to above-mentioned national standard, it can be known that the breaking strength, elongation at break, tearing strength, CBR bursting strength, Peel strength, hydrostatic pressure resistance, dynamic penetration, puncture strength, UV resistance, acid and alkali resistance, oxidation resistance, etc. are better than composite plastic woven bags, plastic woven bags and cartons, and its cost is far lower than iron Barrels, but only comparable to composite plastic woven bags and plastic woven bags. (For the characteristics of composite plastic woven bags, please refer to the national standard GB / T8947-19...

Abstract

An application of the composite earth-work film in packing asphalt is disclosed. Its performance is far superior to that of woven bag or paper bag.

Description

technical field [0001] The invention relates to the application of composite geomembrane on asphalt packaging. Background technique [0002] Due to the characteristics of asphalt and storage and transportation, there are special requirements for its packaging: 1. The inner layer of the packaging material must be able to withstand high temperatures above 120°C; 2. It takes about nine processes from the factory to the user, and the strength must be high. , Anti-drop, anti-puncture, anti-friction; 3. Because the construction and use of asphalt are relatively harsh, it must generally be waterproof, moisture-proof, and UV-resistant. [0003] At present, asphalt is generally packaged in iron drums, composite plastic woven bags, plastic woven bags and cartons. The advantages and disadvantages of these packages are as follows: The advantages of iron drums are high strength, waterproof, moisture-proof, and good appearance. The disadvantages are The cos...
