Xiamen, ChinaPLA 소재란?
폴리락트산(PLA)은 옥수수, 카사바와 같은 재생 가능한 식물 자원에서 추출한 전분으로 만든 새로운 바이오 기반 및 재생 가능한 생분해성 소재입니다.
전분 원료는 당화를 통해 포도당을 얻은 다음 포도당과 특정 균주에서 고순도 젖산으로 발효시킨 다음 일정 분자량의 폴리 젖산을 화학 합성하여 중합 사슬은 다음과 같습니다.
전분(정제) -- - > 포도당(발효) -- - > 젖산(고리형) -- - > 락타이드(중합) -- - > PLA
PLA는 21세기 가장 큰 발전 잠재력을 가진 "그린 플라스틱"입니다. 기계적 물성과 투명성은 우수하지만 결정화 속도가 느리고 내열성이 떨어지는 단점이 있어 대중화와 활용에 한계가 있다. 따라서 일부 강화 방법은 성능을 향상시키기 위해 종종 사용되지만 투명성이나 복잡한 프로세스를 희생합니다.
PLA LGF 소재란?
The rigidity of the fiber makes it play the role of skeleton support in the polymer matrix. When the polymer is heated, the movement of the chain segment is limited, thus improving the heat resistance of the material
At present, carbon fiber and glass fiber can be used to enhance the modification of PLA. Among these fibers, carbon fiber and glass fiber are widely used because of their high strength and modulus.
The composite material was prepared by adding fiber into PLA. After heat treatment, the modification effect of the composite material was the best, and the heat resistance temperature was increased by nearly 40℃ compared with that of pure PLA. Two or more materials with synergistic effect can be added at the same time to improve the thermal performance of PLA. The test results show that the Vica softening temperature of the composites exceeds 140℃.

Frequently asked questions
Q. Does long glass fiber and long carbon fiber injection have special requirements for injection molding machines and molds?
A. There are certainly requirements. Especially from the product design structure, as well as the injection molding machine screw nozzle and mold structure injection molding process must consider the requirements of long fiber.
Q. The product is easy to brittle, so changing to use long fiber reinforced thermoplastic materials can solve this problem?
A. The overall mechanical properties must be improved. The characteristics of long glass fiber and long carbon fiber are the advantages in mechanical properties. It has 1-3 times higher (toughness) than short fiber, and the tensile strength (strength and rigidity) is increased by 0.5-1 times.
Q. When a customer want to develop a new product, how to recommend customers suitable material and characteristics?
A. 신제품에 대한 고객의 기술요구사항, 사용환경, 시험조건 등을 파악하고 다양한 종류의 장섬유 수지 기재 특성에 따른 모델 추천이 필요합니다.
