@daily.diy.crafts: HDPE (High-Density Polyethylene): The most widely used material; features strong impermeability, corrosion resistance, and a long service life (50+ years). It is suitable for critical engineering projects such as landfills, tailings storage facilities, and water conservancy works. LDPE (Low-Density Polyethylene): Offers excellent flexibility and ease of installation, making it suitable for agricultural applications and small-scale water reservoirs. Impermeability: Features a permeability coefficient of 10⁻¹²–10⁻¹⁴ cm/s, rendering it virtually impermeable to water. Durability: Resistant to acids, alkalis, and salts, as well as aging; UV-resistant formulations ensure a service life of 50+ years. Mechanical Properties: Exhibits high tensile strength (HDPE ≥ 20 MPa) and an elongation rate of 300%–500%, allowing it to effectively accommodate foundation settlement. #DIY #diytips #lifehacks #fyp #foryoutiktok
