Polyphenylene sulfide PPS is one of the typical representatives of special engineering plastics, with a linear structure of alternating benzene rings and sulfur atoms. In the condensed structure, PPS is easy to crystallize, crystallinity of nearly 70%, therefore, has good thermal stability, chemical stability and dimensional stability, etc. PPS mainly has the following five performance advantages. (1) excellent heat resistance. pps melting point of more than 280 ℃, heat deflection temperature of more than 260 ℃, and after high-temperature heat aging treatment, the strength retention rate is high. (2) since the flame retardant. PPS itself has flame retardant, without adding flame retardants flame retardant level can reach UL94 V- 0 level. (3) good mechanical properties. PPS is a brittle material, has good creep resistance, high surface hardness, good wear resistance, and carbon fiber and other materials compound, but also shows good self-lubricating properties. (4) excellent chemical resistance, irradiation resistance. pps below 200 ℃ almost insoluble in any solvent, can withstand almost all inorganic substances, radiation dose up to 108Gy. (5) good processing properties. pps melt viscosity is low, as the resin matrix of composite materials, for the reinforcement of the flow of excellent wetting effect. As PPS has the above performance advantages, and compared to other high-performance thermoplastic resins and easy processing, low cost, so become an excellent resin matrix for the manufacture of composite materials. Long glass fiber Glass fiber is an inorganic non-metallic material with excellent performance, is a natural mineral with silica as the main raw material, add specific metal oxide mineral raw materials, mixed evenly, molten at high temperature, molten glass liquid flow through the funnel outflow, in the role of high-speed pull gravitational force is drawn and rapidly cooled and cured into a very fine continuous fiber. Glass fiber monofilament diameter from a few microns to more than twenty microns, equivalent to a hair of 1/20-1/5, each bundle of fiber original filament are composed of hundreds or even thousands of monofilaments. Glass fiber basic properties: The appearance of a smooth cylindrical surface, the cross-section is a complete circle, round cross-section to withstand the load capacity; gas and liquid through the resistance is small, but the surface is smooth so that the holding force of the fiber is small, not conducive to the combination with the resin; density is generally in 2.50-2.70 g/cm3, depending mainly on the glass composition; tensile strength than other natural fibers, synthetic fibers to be high; brittle materials, the elongation at break is very small ; water resistance and acid resistance is good, while alkali resistance is poor. It can be divided into continuous glass fiber, short glass fiber (SGF) and long glass fiber (LGF) by length classification. Long glass fiber is the most widely used glass fiber at present. And Xiamen LFT plastic composite company is focuses on the produce of long glass fiber compounds for many years. SGF VS LGF 1. サイズの長さの違い エンジニアリング材料の長いガラス繊維と短いガラス繊維は、文字通りサイズの長さの違いを意味します。より一般的な短いガラス繊維のサイズは約 0.2mm ～ 0.6mm です。長いガラス繊維のサイズは約6mm〜25mmです。 2. 性能強度の違い ガラス繊維の長さが異なると性能強度が異なり、複合材料内の長いガラス繊維の繊維長は、短いガラス繊維よりも衝撃強度が高くなります。 3. 製造プロセスが異なります 長ガラス繊維の製造では、原料に対する高い要求があり、特に製造プロセスではガラス繊維の表面を活性化する必要があり、加工中にガラス繊維を浸み込ませることができず、外部漏れ現象が発生します。ガラス短繊維の製造は、一般にサイズに特別な要件がないため、製造が比較的容易であり、原材料の要件がそれほど高くなく、製造業者の製造コストが低い。 4. さまざまな製造および加工方法 長ガラス繊維の製造および加工方法には、一般に射出成形と成形が使用されます。一方、最も短いガラス繊維の射出成形法。 製品プロセス TDS は参考のみ 詳細 番号 色 長さ サンプル パッキング MOQ 積荷港 納期 PPS-NA-LGF40 元の色 (または必要に応じて) 12mm (または必要に応じて) 利用可能 25kg/袋 25kg 厦門港 発送後7~15日 私たちを選ぶ理由 1.
