RIETTI罗米特PP-R 新型增韧双色管采用新型高分子白色纳米和增韧复合材料经挤塑成型，具有蠕动快、卫生、自洁于一体等优点，有效抑制各种微生物生长，避免冷热水尤其是高温热水状态下不滋生细菌，持久性和安全性优越，同时也杜绝管道在外露阳光直射环境下，因光合作用而产生的藻类生长。并在内外层结构上优化设计和改进生产工艺，令其产品韧性有显著提高，因此此管道不仅可直接用于纯净水输送系统，其耐热环境下耐压更强，冷热伸缩系数更小，不易变形。

The white layer on inner wall of RIETTI 罗米特 PP-R new toughened bicolor tube is made of new nano and polymer toughened composite materials, It is formed by extrusion process,

 It has the advantages of fast creeping, sanitation and self-cleaning, Effectively inhibit growth of various microorganisms, and prevent bacteria from growing in hot and cold water, especially in hot and hot water, Persistence and security, At the same time, The pipes shall not be exposed to direct sunlight, Algal growth due to photosynthesis. In addition, we optimized design and improved production process in terms of the internal and external structure, and significantly improved the toughness, Therefore, this pipes can not only be directly used in purified water transmission system, Its resistance to heat is stronger and its thermal expansion coefficient is smaller.
