The lion dance is here to celebrate—may your new year be filled with prosperity and success!

Lion dance to celebrate—may your new year be auspicious! On the eighth day of the first lunar month, February 12, amid the lingering joy of the Spring Festival, Jinbang Company officially kicked off its new year. Cheers, firecrackers, gongs and drums—every sound resounds, every note rings out, heralding the arrival of the New Year and sounding the call to begin the year ahead! A fresh start, a vibrant scene, and a world renewed! On this wonderful day, perhaps you harbor hopes for even greater prosperity in your company, as well as for harmony and success in your personal life, career, and health. Well, the company has invited the professional lion dance troupe “Waicun Dragon and Lion Troupe” to bring festive cheer, welcome the new year, and offer their blessings. Two spirited lions danced at the company entrance, in front of the office building, and by the workshop doors—shaking their heads, circling, leaping, and presenting gifts to all who gathered. Accompanied by the lively beats of drums and gongs, employees also began traditional rituals of worshipping the gods and offering incense. As wisps of smoke rose gently, everyone silently prayed for thriving business, for good fortune in the coming year, and for everything to go smoothly. Chairman Luo and other members of the management team distributed red envelopes to employees on the spot, bringing smiles to their faces and exchanging the warmest wishes. With drums booming and festivities in full swing, Jinbang Company is poised for even greater success! In 2019—the Year of the Golden Pig—let us move forward together, strive together, and shine brightly together!

How much do you know about sheet materials? — Report on the “Fundamentals of Sheet Materials” Training Course

Report on the “Basic Knowledge of Sheet Materials” Training Session 1 To further deepen Jinbang employees’ understanding of sheet material knowledge, on January 9, 2019, the head of the Technical Quality Department delivered a training session titled “Basic Knowledge of Sheet Materials.” During the session, the instructor provided an in-depth explanation of polyvinyl chloride (PVC) sheet materials, covering their composition, processing principles, applications, and an overview of additives. The instructor also cited common issues encountered with sheet materials and outlined corresponding solutions, greatly benefiting all participants. Speaker: Head of the Technical Quality Department After the lecture, attendees actively raised their questions, which the instructor addressed using his professional expertise. It is believed that, through this training session, everyone has gained a more profound understanding of sheet material knowledge. Quick Guide to Key Concepts Polyvinyl chloride, abbreviated as PVC in English (Polyvinylchloride), is a polymer formed via free-radical polymerization of vinyl chloride monomer (VCM) under the action of initiators such as peroxides or azo compounds, or through exposure to light and heat. ❖ PVC Structure PVC appears as a white, amorphous powder with low branching. Its relative density is around 1.4, its glass transition temperature ranges from 77 to 90°C, and it begins to decompose at approximately 170°C. PVC exhibits poor stability against light and heat; when exposed to temperatures above 100°C or prolonged sunlight, it breaks down, releasing hydrogen chloride, which then triggers further autocatalytic decomposition, leading to discoloration and a rapid decline in physical and mechanical properties. Therefore, stabilizers must be added in practical applications to enhance thermal and light stability. Industrially produced PVC typically has a molecular weight ranging from 50,000 to 110,000, showing significant polydispersity. Molecular weight increases as the polymerization temperature decreases. PVC lacks a fixed melting point: it starts to soften at 80–85°C, transitions into a viscoelastic state at 130°C, and becomes viscous-flowing at 160–180°C. It possesses good mechanical properties, with tensile strength around 60 MPa and impact strength of 5–10 kJ/m², along with excellent dielectric performance. PVC was once the world’s highest‑produced general‑purpose plastic and enjoys extremely broad applications. It is widely used in building materials, industrial products, daily necessities, floor coverings, floor tiles, synthetic leather, pipes, wires and cables, packaging films, bottles, foamed materials, sealing materials, fibers, and many other fields.
