알루미늄 합금 다이캐스팅의 단점을 해결하는 것이 편리합니다!

알루미늄 합금 다이캐스팅은 현재 현재의 전자제품, 자동차, 생활필수품 많은 산업과 분야에서 널리 사용되고 있습니다. 그러나 알루미늄 합금 다이캐스팅에서 자주 발생하는 가지 결함 해결 방법은 다음과 같습니다.

 

알루미늄 합금 다이캐스팅

 

1. 불순물

 

알루미늄 합금 다이 캐스팅의 불순물 문제는 주로 특정 온도에서 알루미늄, 규소 다량의 , 망간, 크롬 기타 화합물을 포함하는 결정립과 일부 산화물로 구성됩니다.

 

해결책: 알루미늄 잉곳의 조성을 엄격하게 제어하고, 제련로의 난로를 정기적으로 청소하고, 정기적으로 슬래그를 처리하면 문제를 해결할 있습니다.

 

2. 구강 문제

 

다공성은 다이캐스팅 부품의 내부 또는 표면에 나타나는 다양한 크기의 구멍을 말하며, 이는 다이캐스팅 부품의 경도 부족으로 이어져 표면의 외관에 영향을 줍니다.

 

Solution: 적절한 정제제를 사용하여 모공을 처리하고, 공정을 조정하고, 저속을 적절하게 줄이고, 이형제가 너무 많이 분사되어 모공 문제가 해결되지 않는지 확인하십시오.

The Connection Between Heart Health and Hearing Health

Posted: 15 Jul 2022 07:01 AM PDT


This is a sponsored blog post from HLAA Hear for Life Partner, Starkey.

Does it surprise you that neglecting your cardiovascular health could spell trouble for your hearing? Starkey Chief Health Officer Archelle Georgiou, M.D., offers insights on this important connection and how to stay healthy.

Normal blood flow is critical for good hearing health. Delicate hair cells in the inner ear (the cochlea) turn sound into electrical impulses that travel to the brain so we can hear speech, music or noise. Those hair cells rely on good circulation to function properly. Heart disease or hypertension can decrease blood flow to the inner ear, depriving hair cells of oxygen, which can permanently damage hearing.

People can take care of their cardiovascular systems by staying physically active, maintaining a healthy weight, and not smoking. Everyone should also know their blood pressure, cholesterol level, and hemoglobin AIC, which is elevated in people with diabetes. If you do have high blood pressure, diabetes, or high cholesterol, make sure to talk to a doctor about taking the right medication at the proper dosage to get your numbers into a normal range. By taking care of the cardiovascular system, you will also be proactively protecting your hearing.

Consider these studies and stats which show the link between cardiovascular risk factors and hearing loss:

  • Hearing loss is twice as common in people who have diabetes. Even people with prediabetes (blood sugar levels higher than normal but not high enough yet to have type 2 diabetes) have a 30% higher rate of hearing loss than people with normal blood sugar levels.

If you think you, or a loved one, has a hearing loss, don't wait! Get your hearing checked today. For more information on hearing health, visit hearing.org.
