What is the harm of tungsten electrode to human body? what are the new environmental protection decoration materials?
In fact, the choice of home decoration brand and materials, should pay special attention to the quality of materials and the selection of methods. If the quality of materials is not high, problems often occur in the process of selection, which may affect the quality of life of individual homes. At this time you can also see what tungsten pole harm to the human body, to understand the new environmental protection decoration materials, the choice of high-quality environmental protection materials, for the future home life is very critical.
What is the harm of the tungsten electrode to the human body The tungsten electrode is a radioactive element, a high-frequency electromagnetic field is formed, harmful gas is generated, and the like, and the loss of the human body is relatively large. 1. Radioactivity The tungsten in the tungsten-tungsten electrode is an element, but the radiation dose of the tungsten-tungsten electrode is very small at the time of the argon-arc welding of the tungsten. If that radioactive gas or the particle enter the human body as an internal radiation source, the body is seriously affected. 2. High-frequency electromagnetic field The high-frequency electric field intensity is between 60 and 110 V/ m, which is several times higher than the reference standard (20 V/ m). But due to the short time, the effect on the human body is not small. The high-frequency electromagnetic field can become one of the harmful factors if the arc is frequently started or the high-frequency oscillator is used as the arc-stabilizing device for continuous use during the welding process. 3. Harmful gas When the argon arc welding of ozone and nitrogen oxide, the temperature of the arc column is high. The radiation intensity of the ultraviolet rays is much higher than that of the general electric arc welding, so a large amount of ozone and oxynitride are generated during the welding process; in particular, the concentration of the ozone is far beyond the reference hygienic standard. If we do not take effective ventilation measures, the influence of these gases on the health of the human body is very large, which is the most important harmful factor of the argon arc welding.
What are the new environment-friendly decorative materials 1. Insect-proof and mildew-proof coating: The anti-insect and mildew-proof coating refers to the coating which is made of materials with biological toxicity under the condition that the paint is decorated. The material is not only high in efficiency, but also does not cause harm to the human body. 2. Plant fiber coating: the coating is a natural recycled fiber, and is a spray-coated sound-absorbing decorative material prepared by the following steps of: crushing waste paper, bark and the like and after being subjected to chemical treatment. 3. Wood-wire sound-absorbing board: The material is made of long-fiber and natural magnesite powder and cement, so it does not contain any adhesive, and it is also very beautiful. In addition, that wood-wire sound-absorbing plate can not only be mould-proof, but also can be damp-proof, and is generally used for decoration sound absorption or sound absorption in a sound-insulation wall body. The above introduction is what the tungsten electrode is harmful to the human body and what is the new type of environment-friendly decorative material. It is hoped that some suitable decorative materials can be selected, and the effect will be better later. In fact, the environment-friendly decorative material is very much, such as the insect-proof and mould-proof coating and the coating of the plant fiber, and also has a lot of safety material materials. And the environment-friendly materials are very popular now, so the selection is to be taken into consideration.
