This mission has culminated in a comprehensive array of integrated solutions, featuring the Zhong Qiao Tank Horizontal Tank A/B, Vertical Tank A/B, and the pioneering Hollow Tank, all embodying unparalleled ingenuity and excellence.
II. Superior Raw Materials
Our unwavering dedication to excellence is epitomized by our selection of high-modulus polypropylene as the cornerstone of our underground drainage and wastewater solutions. Boasting an impressive elastic modulus of ≥1500 MPa-far exceeding HDPE's 800 MPa-it ensures exceptional ring stiffness and robust structural integrity, vital for high-performance applications.
Polypropylene, distinguished by its non-toxic, odorless nature, exhibits a highly crystalline structure and ultra-light density of 0.90-0.91 g/cm³, with outstanding water stability evidenced by a mere 0.01% absorption rate. Furthermore, its molecular weights span 80,000 to 150,000, allowing polypropylene to excel in molding capabilities, presenting a refined, attractive finish, ideal for a myriad of applications.
Polypropylene's exceptional chemical stability allows it to endure various chemicals; caution is advised only with concentrated sulfuric and nitric acids. Although it may interact with some hydrocarbons, its heightened crystallinity enhances its chemical resistance, making it an ideal choice for crafting durable, corrosion-resistant components across numerous applications.
As a non-toxic and odor-free material, polypropylene surpasses low-density polyethylene with superior strength, stiffness, and heat resistance, performing exceptionally near 100°C. Its excellent dielectric properties and high-frequency insulation remain impervious to moisture, rendering it versatile for a wide range of industrial and commercial applications.
Exhibiting exceptional resistance to common acids, bases, and organic solvents, polypropylene is perfectly suited for food-grade utensil applications where safety and durability are paramount.
PPH, marked by its high molecular weight and low melt flow homopolypropylene, is enhanced by β-modification, resulting in a finely crystalline structure that bolsters its chemical and temperature endurance, creep resistance, and impact resilience at low temperatures, making it ideal for demanding environments.
