| Round Sushi tray-5a ps material modification Polyst yrene (PS) is the most widely used thermoplastic in the world today. Due to its advantages of good water resistance, formability, transparency, rigidity and low price, Round Sushi tray-5a ps material is widely used in packaging, heat preservation, waterproofing, heat insulation, shock absorption, decoration, catering and other fields, Infiltrate all areas of the national economy. According to statistics, in the past ten years, the average annual growth rate of PS consumption has reached more than 10%. With the rapid development of electronic instruments and household appliances industry, it is estimated that its consumption will be larger and larger. Since the impact strength is a soft underbelly of the material properties of Round Sushi tray-5a ps, its application is greatly limited. Therefore, through the research and modification of formulations and reagents to improve the impact properties of Round Sushi tray-5a ps materials so as to adapt their properties to processing and use requirements, it has always become a market-leading and constantly seeking novelty. The goal pursued by plastic enterprises.Modifica tion method of Round Sushi tray-5a PS material: blending modification 1. Round Sushi tray-5a PS/PE Polyethylen e (PE) has excellent flexibility and impact resistance, which is beneficial to improve the toughness of Round Sushi tray-5a PS. However, Round Sushi tray-5a PS and PE are two incompatible polymers, and appropriate compatibilizers should be added during blending modification. Blending of Round Sushi tray-5a PS with PE can be achieved in two ways, reactive blending and non-reactive blending. In the study of reactive blending, reinforced Round Sushi tray-5a PS (RPS), hydroxylated PE (CPE), PE and Round Sushi tray-5a PS were simultaneously fed into a twin-screw extruder for melt blending and extrusion. Blend modified PS. Note: The increase in the relative molecular weight of PE does not affect the tensile strength of the blend, but also improves the impact strength of the blend. 2. Round Sushi tray-5a PS/PP Polypropyle ne (PP) has higher tensile strength and surface hardness than Round Sushi tray-5a PS, and has better heat resistance, so blending it with Round Sushi tray-5a PS can improve the heat resistance of Round Sushi tray-5a PS. performance. Howe ver, PP is not compatible with Round Sushi tray-5a PS, so a compatibilizer needs to be added. The commonly used surface-treated silicon-filled Round Sushi tray-5a PS/PP system can increase the adhesion between the polymer interfaces and improve the tensile strength of the Round Sushi tray-5a PS/PP system. Maleic anhydride functionalized polypropylene (RPS-MPP) also has a good reaction compatibilization effect on Round Sushi tray-5a PS/PP. 3. Round Sushi tray-5a PS/PC Polycarbona te (PC) has excellent performance, good creep resistance, visible light transmittance of more than 90%, similar to the refractive index of Round Sushi tray-5a PS, and can be blended with Round Sushi tray-5a PS to make Round The thermal stability, strength and toughness of Sushi tray-5a PS were improved. When the partially compatible Round Sushi tray-5a PS/PC is subjected to external force, the stress distribution of the phase interface is uniform and continuous, so the impact and tensile external force cause the blend to produce silver streaks and shear bands, thereby improving the Round Sushi tray. Mechanical properties of -5a PS/PC blends. Round Sushi tray-5a：https://ww w.90pluspak.com/Roun d-Sushi-tray-5a.html | |
