특징

마코르 세라믹은 여러 가지 매력적인 특성을 가진 매우 독특하고 유용한 재료입니다.

1. 우수한 기계적 특성 및 적용

기계식 세라믹은 높은 경도, 높은 강도 및 우수한 압축 강도를 포함하여 탁월한 기계적 특성을 가지고 있습니다. 이것들 

속성은 기계식 세라믹을 많은 산업 응용 분야, 특히 재료가 극한의 힘을 견뎌야 하는 환경에서 이상적으로 만듭니다. 

마모.

높은 경도 및 강도:

록웰 경도:
R45N = 40.

비커스 경도(500g 부하):
11.5 GPa(1175 Kg/mm2).

탄성 계수:
25℃에서 65 GPa.

굴곡 강도:
20℃에서 108 MPa.

압축 강도:
20℃에서 488 MPa.

이러한 기계적 특성으로 인해 기계식 세라믹은 충격과 응력 하에서 안정적으로 유지되어 파손 가능성을 줄일 수 있습니다. 높기 때문에 

강도 및 내마모성, 기계식 세라믹은 부품과 같은 다양한 고성능 산업용 부품을 제조하는 데 자주 사용됩니다. 

밀링 머신, 슬라이딩 부품 및 절삭 공구 인서트.

2. 우수한 열 특성

기계식 세라믹은 또한 고온 안정성, 낮은 열팽창 계수 및 양호한 열역학적 특성을 가지고 있습니다. 

열 충격 저항.

최대 작동 온도:
800℃.

열전도율:
25℃에서 1.71 W/(m·K).

열팽창 계수:
7.2 10⁻⁶/℃.

열충격 저항:
200℃.

이러한 특성은 열 절연 또는 열 보존이 필요한 응용 분야에서 기계식 세라믹을 매우 유용하게 만듭니다. 예를 들어, 특정 

화학 공정 장비 및 고온 용해로, 가공 가능한 세라믹을 단열 층으로 사용하여 온도를 제어하고 보호할 수 있습니다. 

과열 손상으로 인한 민감한 기계적 구성 요소.

3. 우수한 전기 성능

기계식 세라믹은 또한 우수한 전기 절연 특성을 가지고 있어 전자 및 전기 응용 분야에서 매우 가치가 있습니다.

분해 강도(절연 강도):
30kV/mm.

20℃에서의 체적 저항성:
20℃에서 10·cm.

이러한 전기적 특성은 기계식 세라믹을 고전압 및 고주파 응용 분야에서 매우 효과적으로 만들어 안정적인 절연 보호를 제공합니다.

이 기계식 세라믹 재료는 특히 높은 경도, 높은 경도를 요구하는 분야에서 다양한 까다로운 응용 분야에서 탁월한 성능을 발휘합니다. 

강도, 우수한 열 및 전기적 특성.
