[Book] Measures Against Degradation and Discoloration of Polymer Materials (No. 2104BOD)

Technical Specialized Books - Mechanisms of Degradation, Optimal Formulation of Additives, Product Troubles and Countermeasures, Analysis and Evaluation.

■ Points of this Book Understanding the mechanisms of degradation and discoloration of polymer materials - How do auto-oxidative degradation and discoloration progress under the influence of light, heat, and metal ions? - What factors promote hydrolysis? - How can we prevent cracking caused by solvents, oils, surfactants, and other chemicals? - The degradation mechanisms and stabilization of various materials such as thermosetting resins, thermoplastics, and composite materials. Optimal formulation of additives - Formulations considering antagonistic effects, compatibility, and migration. - Responses when antioxidants themselves discolor. - Synergistic effects and antagonistic actions of UVA/HALS. - Prevention of poor dispersion and blooming caused by metal inactivators. - Selection of antibacterial and antifungal agents according to purpose. - Selection of curing agents considering cost, safety, and lifespan. - Mechanisms of bleed-out occurrence and countermeasures. Troubles and countermeasures for polymer products - Degradation and prevention of protective coatings on automobiles due to temperature, pollen, bird droppings, stones, etc. - Scratch resistance, chemical resistance, and hardness in automotive decorative films. - How to meet the safety, reliability, and strength required in the railway sector? - Troubles such as burning and odor in packaging materials and their countermeasures. - Durability, seismic resistance, fire resistance... what are the required properties in the construction field?

Contec Co., Ltd. has started selling the "SH-9210TSN," an industrial managed switching hub that has obtained CC-Link IE TSN recommended network wiring component certification Class B. It features dual power supply redundancy, a DC power input, eight gigabit ports, and two SFP slots. The SH-9210TSN complies with IEEE 802.3ab (1000BASE-T), IEEE 802.3u (100BASE-TX), and IEEE 802.3 (10BASE-T) standards, and is designed for use in environments where quiet operation and long lifespan are required due to its fanless design. Additionally, it achieves an operating temperature range of -10 to 65°C thanks to its excellent heat dissipation metal casing. It can be installed on a 35mm DIN rail or mounted on walls using various mounting brackets. In addition to a wide-range DC power input (12-48VDC), it supports input from two power supply lines and includes various managed functions for network management, control, and reliability enhancement.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
