A influência do nitrogênio impuro na máquina de corte a laser


A aplicação de nitrogênio em máquinas de corte a laser é usada principalmente como gás auxiliar no corte de aço inoxidável! A influência do nitrogênio impuro na máquina de corte a laser.

O nitrogênio tem duas funções como gás auxiliar para aço inoxidável

1. O nitrogênio é um gás inerte, que impede a reação de oxidação no corte a laser. Mantenha o brilho metálico (brilhante) da superfície de corte dos produtos de aço inoxidável.

2. Sopre a peça derretida a laser com pressão de nitrogênio para formar uma costura de corte!

Geralmente, corte a laser tem vários requisitos para nitrogênio:

 influence of nitrogen impure
influence of nitrogen impure


Geralmente, os requisitos de pureza são maiores do que 99.99%, quanto maior, melhor! O motivo é manter o brilho metálico original do aço inoxidável no corte superfície durante o corte de aço inoxidável! Se a pureza for muito baixa, a superfície de corte será produzida. A reação de oxidação resulta em amarelecimento ou escurecimento da superfície de corte. Influência de nitrogênio impuro


A pressão dependerá da espessura do aço inoxidável cortado. Geralmente, 1Mpa abaixo de 10 mm é suficiente. Se você deseja cortar aço inoxidável de 20 mm, a pressão do nitrogênio é geralmente 2Mpa ou superior.


A vazão será determinada pelo diâmetro e pressão do bico de corte. Claro, o principal motivo é a espessura do aço inoxidável cortado. Se for de chapa grossa de aço inoxidável, o fluxo será muito grande!

Nitrogen is a chemical element present in various forms and quantities in different materials and processes. Its influence can be both advantageous and detrimental, depending on the context. This comprehensive exploration delves into the multifaceted impact of nitrogen impurities, examining their effects on various materials, industries, and applications.

3.1 Eutrophication: Nitrogen impurities, often in the form of nitrates and ammonium, can lead to eutrophication when they enter water bodies. This excessive nutrient input can cause harmful algal blooms and oxygen depletion, disrupting aquatic ecosystems.

3.2 Air Pollution: Nitrogen oxides (NOx), released from combustion processes, contribute to air pollution, forming smog and adversely affecting air quality. These pollutants have direct health impacts on humans.

Section 4: Nitrogen in Chemical Reactions and Industries (200 words)

4.1 Inert Atmosphere: Nitrogen gas is a commonly used inert atmosphere in chemical reactions to prevent undesired reactions and protect sensitive materials from oxidation.

4.2 Nitrogen Blanketing: In food packaging and storage, nitrogen is employed to create a nitrogen-rich environment inside packaging, extending the shelf life of products by reducing oxidative spoilage.

Section 5: Nitrogen in Biological Systems and Health (200 words)

5.1 Nitrogen Fixation: Nitrogen impurities play a critical role in agriculture. Nitrogen-fixing bacteria convert atmospheric nitrogen into ammonia, enriching the soil with nitrogen nutrients essential for plant growth.

5.2 Health Implications: Nitrogen impurities in the form of nitrates and nitrites can be found in food and water. In excessive quantities, they pose health risks, particularly to infants, with potential links to conditions like methemoglobinemia.

Section 6: Managing Nitrogen Impurities (100 words)

6.1 Control and Regulation: Proper management and control of nitrogen impurities are essential to harness their benefits while mitigating adverse effects. Regulations on nitrogen emissions in industries and agricultural practices aim to minimize environmental impact.

Conclusion (150 words)

Nitrogen impurities exert a multifaceted influence on materials, industries, and the environment. While they can enhance the strength of metals, improve electronic properties, and support agricultural productivity, nitrogen impurities also contribute to challenges such as eutrophication, air pollution, and health concerns. Managing and regulating the presence of nitrogen impurities are crucial steps toward leveraging their advantages while addressing their potential drawbacks. Understanding the intricate balance of nitrogen’s influence across various sectors is essential for responsible and sustainable practices in our interconnected world.
