لقد حان شبكة اتصالات 5G ، وهو علم وتكنولوجيا جديد ، كما أن تطوير مواد البوليمر يجلب فرصًا جديدة ، ويستعد موردو المواد عالية الأداء بنشاط للمواد اللازمة لاتصالات 5G. من بينها ، يمكن استخدام المواد المركبة المقواة بالألياف الطويلة LFT في محطة رادوم 5G الأساسية وإطار المعدات والقوس والمرشح والجوانب الأخرى ويفضل. اليوم سنتحدث عن مادة LFT.

1. Definition and characteristics of LDT-PP

long fiber reinforced thermoplastics (LFT) refers to long, continuous glass fibers, After special process is fully infiltrated by resin, wait until the strip, and then cut into a specific size glass fiber reinforced rubber particles or resin soaked long glass fiber strip directly molded or injection molding material. The length of glass fiber in LFT materials is generally more than 3 mm, and its application and development goal is to be used as semi-structural and structural materials.

Among them, the LFT composites based on polypropylene PP have the advantages of light weight and high strength, easy manufacturing and cost optimization. As a new high performance engineering plastics, it has been widely used. Currently, it is the first choice of polymer matrix composites for automotive lightweight.

2. Preparation process of LFT-PP

According to the preparation technology, the LFT-PP high performance composites can be divided into two categories: LFT-G process and LFT-D-ILC process.

2.1 LDT-G process

Firstly, through the mixing of resin, glass fiber and additives, LFT-G long fiber pellets are prepared by special melt impregnation composite method, and then the final product is finished by injection molding process.

The fiber length of LFT varies with the processing process. Impact properties are particularly dependent on the length of the glass fiber. The length of commercial LFT-G colloidal particles is generally 6 ~ 25mm. The LDT-G composite supports semi-mechanism automotive applications, such as front end components, door components, instrument bearers, tailgate and seating systems, combining lightweight and functionality.

2.2 LFT-D-ILC process

The LDT-D-ILC is called the long fiber reinforced thermoplastic material online molding process technology. This process, the online mixing system is integrated in the molding process, matrix particles and additives are transported to the gravimetric feeding unit combination, which ensures appropriate mixing according to the mechanical properties of the component requirements.

3. دليل التطبيق في مجال السيارات LFT-PP

: لا يمكن لمواد LFT-PP تحسين الصلابة وقوة التأثير ومقاومة الزحف واستقرار الأبعاد للمنتجات النهائية فحسب ، بل تقلل أيضًا من تكلفة تصنيع وحدات السيارات ، وتقصير دورة التشكيل ، وإعداد وحدات متطورة للسيارات.

مجال 5G: يمكن استخدام المواد المعدلة LFT في محطات 5G الأساسية ؛ يمكن استخدام الهاتف المحمول في غلاف الهاتف المحمول والغطاء الخلفي والبطارية والرقاقة والمكونات الأخرى.
