Problems solved by technology

[0002] Plastics are widely used in people's daily life because of their simple preparation and low price. However, plastics on the market will deform if they encounter liquids with high temperatures during use, which limits their use, especially in household hot water. During the use of pipes or kitchen sewer pipes, due to long-term contact with high-temperature liquids or corrosive sundries, the pipes are particularly prone to corrosion, deformation, and aging, resulting in inconvenience in use. Therefore, the existing plastics need further improvement
