Fibra de carbono longa PA6 Polyamide6 de alto desempenho para peças automotivas cor original

PA6 Apresentar

A cadeia principal de poliamida contém muitos grupos amida repetidos, usados ​​como um plástico chamado nylon, usado como uma fibra sintética chamada nylon. Uma variedade de diferentes poliamidas pode ser preparada de acordo com o número de átomos de carbono contidos em aminas binárias e ácidos dibásicos ou aminoácidos. Atualmente, existem dezenas de poliamidas, entre as quais a poliamida-6, a poliamida-66 e a poliamida-610 são as mais utilizadas.

A poliamida-6 é uma poliamida alifática, com peso leve, forte resistência, resistência ao desgaste, resistência a ácidos e álcalis fracos e alguns solventes orgânicos, fácil de formar e processar e outras excelentes propriedades, amplamente utilizada em fibras, plásticos de engenharia e campos de filmes.

No entanto, o segmento da cadeia molecular de PA6 contém grupos amida altamente polares, que são fáceis de formar ligações de hidrogênio com moléculas de água. O produto apresenta deficiências como alta absorção de água, baixa estabilidade dimensional, baixa resistência ao impacto em estado seco e baixa temperatura e baixa resistência a ácidos e álcalis fortes.

modificação

Filling reinforced modification

Filling enhancement modification is a commonly used method for physical modification of PA6. It refers to the modification of PA6 by adding glass fiber, carbon fiber, whisker, wollastonite, calcium carbonate, talc powder, rare earth, mica, silica and other fillers into the matrix to significantly improve the mechanical properties, flame retardant properties, thermal conductivity and dimensional stability of the material.

Xiamen LFT composite plastic Co., Ltd. is a brand-name company's thermoplastic LFT can be used for LFT-G injection molding and extrusion, and can also be used for LFT-D molding. It can be produced according to customer requirements: 5~25mm length.

Material application

Including impact resistant nylon, reinforced high temperature resistant nylon, etc., used to make appliances with special needs, such as reinforced high temperature resistant nylon can be used to make impact drill, lawn mower, etc.

At present, there are many kinds of PA6 automobile products. For example, radiator box, heater box, radiator blade, steering column cover, tail lampshade, timing gear cover, fan blade, various gears, radiator water chamber, air filter housing, intake manifold, control switch, intake conduit, vacuum connection pipe, airbag, electrical instrument housing, wiper, pump impeller, bearing, bushing, valve seat, door handle, wheel cover, etc. In short, It involves automobile engine parts, electrical parts, body parts and airbags.

Frequently asked questions

1. How to choose the fiber content of the product? Is the larger product suitable for higher fiber content material?

A. This is not absolute. The content of glass fiber is not more is better. The suitable content is just to meet the requirements of each products.

2. If a product is easily deformed, can we solve the problem by replacing with a long fiber reinforced thermoplastic?

A. Long glass fiber and Long carbon fiber features low warpage and dimensional stability, which can improve part of the deformation.

3. 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 and nylon long glass fiber is replacing PPS series.
