длинное углеродное волокно pa66 переработка гранул полиамид66 нейлоновые гранулы

высокое качество pa66 черный материал с высокой прочностью

Введение материала В 1935 году Уоллес Карозерс, научный сотрудник DuPont, и его команда впервые успешно синтезировали PA66 путем конденсации адипиновой кислоты и адипинового диамина, а DuPont завершила коммерческое производство волокна PA66 в 1939 году. Начиная с 1950-х годов, PA , включая PA6 и PA66, был разработан для производства изделий, изготовленных литьем под давлением, для замены металла, чтобы удовлетворить требования легкого веса и снижения стоимости промышленных продуктов. В настоящее время PA66 является наиболее используемой разновидностью PA, кроме PA6. PA66 Научное название: полигександиамид. Сокращение: PA66. Общепринятое название: нейлон 66.  PA66 имеет много общего с PA6. PA66 также представляет собой гранулы от прозрачного до молочно-белого цвета, которые могут приобретать практически любой цвет при добавлении красителя (маточной смеси), характерного для полимеров. Свойства материала Similar to the basic properties of PA6, PA66 also has low specific gravity, high tensile strength, wear resistance, good self-lubrication, and excellent impact toughness. In addition, because the number of hydrogen bonds in PA66 is more than in PA6, the intermolecular force of PA66 is stronger than the intermolecular force of PA6, which makes the internal structure of PA66 more compact than PA6, with better thermal properties, higher rigidity and toughness, better dimensional stability, lower water absorption, and more wear resistance. However, PA66 has a higher market price than PA6 and is not as easy to process and mold as PA6. Like PA6, PA66 can also add a certain percentage of glass fiber, carbon fiber, etc. to improve the performance and meet the application needs of different products. The following table is a PA66-LCF30 performance table produced by Xiamen LFT composite plastic company. Materials Application PA66 has higher hardness, mechanical strength, toughness, self-lubrication, friction resistance, heat resistance after the addition of carbon fiber, and is widely used in automotive parts, electrical and electronic, as well as mechanical and engineering parts and other fields. Automotive parts PA66's low specific gravity, high rigidity, strong toughness, heat resistance and gasoline resistance make it widely used in automotive modules, automotive structural parts, automotive interior and exterior parts, automotive transmission system and chassis shield, automotive fuel system, automotive ignition system, etc. The products involve automotive cable channel modules, structural parts of front-end components of automotive sunroof system, automotive rearview mirror bracket, automotive radiator, headlight support frame, door module, seat structural parts, seat shell and backrest, dashboard skeleton, air cooler fan, etc. Electrical and electronics PA66's good insulation, flame retardancy and corrosion resistance make it suitable for making various connectors, switches, sockets, terminal blocks, wire coverings, wire ties, insulating spacers, circuit breaker housings, transformer bobbins, retaining clips and motor parts after glass fiber reinforcement. Mechanical and engineering parts PA66's good rigidity, toughness, self-lubricating properties, heat and abrasion resistance make it suitable for manufacturing various nuts, screws, cable ties, worm gears, rotating wheels, gears, pump impellers, pulley sleeves, bushings, solenoid distribution valve seats, power tool housings, pipes, luggage racks, fan housings, appliance housings, door and window frames, cable drag chains and large machine tool baffles.

How to choose the reinforcement method and length of the material when using long fiber reinforced thermoplastic material? A.  The selection of materials depend on the requirements of the products. It is necessary to access how much the content is enhanced and how much length is more appropriate, which are depending on the performance requirements of the products. Q. Under what circumstances can long fiber replace short fiber? What are the common alternative materials? A. Traditional staple fiber materials can be replaced with long glass fiber and long carbon fiber LFT materials in the case of customers whose mechanical properties cannot be met or where higher metal substitutes are desired. For example, PP long glass fiber is often replacing nylon reinforced glass fiber, a...
