The Gas Protection Welding Wire is a type of copper-plated low alloy steel gas shielded Welding wire, using carbon dioxide or argon-rich as the shielding gas for welding. It has excellent welding process performance, stable arc combustion, less spatter, beautiful weld forming, small sensitivity of weld metal porosity, good welding technology in all position, and can be suitable for a wide range of welding current.

After the renovation of the new house, there is a pungent smell, commonly known as formaldehyde. People often take measures to open windows for ventilation. The release period of formaldehyde is as long as 3 to 15 years. This does not solve the problem at the source. So, how to solve the root cause, this article will explain it in detail for you.
01
The source of formaldehyde has recently been reported by the media. Some inferior melamine bowls in public places such as snack bars and canteens have exceeded formaldehyde levels by as much as 8 times in hot and hot oil conditions. This report has caused great repercussions and made people feel that everything Suspicious things create fear. In fact, the figure of formaldehyde is everywhere: car exhaust, plastic chemicals, cosmetics, books, carpets, sofas, floors, even curtains, desks, etc., are almost everywhere. Especially in newly renovated rooms, formaldehyde can be described as pervasive, and is known as the "top killer" of renovation pollution.
02
Formaldehyde hazards Formaldehyde ranks second in the list of chemicals that China's toxic chemicals have priority to control. It has been identified by the World Health Organization as a carcinogenic and teratogenic substance. Studies have shown that formaldehyde has a strong carcinogenic and cancer-promoting effect. As early as in 2009, the United States National Cancer Institute released a study that showed that people exposed to formaldehyde for a long time had a much higher chance of suffering from Hodgkin's lymphoma, multiple myeloma, myeloid leukemia and other special cancers.
In addition, studies have confirmed that chronic exposure to low doses of formaldehyde can cause chronic respiratory diseases, which can lead to headaches, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, sore throat, poor appetite, palpitations, insomnia, weight loss. , memory loss and autonomic disorders; men long-term inhalation can lead to male sperm abnormalities, death; long-term inhalation of pregnant women may lead to fetal malformations, and even death. It is worth emphasizing that children and pregnant women are particularly sensitive to formaldehyde and more harmful to the exposed population. There are no fewer deaths caused by excessive formaldehyde.

How to avoid the harm of formaldehyde to the human body In general, the pungent environment after the new decoration is more likely to attract people's attention. Once the odor is reduced or disappeared, the public's awareness of preparedness is also reduced. But is there no formaldehyde without taste? The answer is obviously negative. Studies have shown that the long period of formaldehyde release and the complete release of formaldehyde from man-made boards usually takes 8 to 15 years. Therefore, simply opening the window for ventilation for several months cannot fundamentally solve the problem. Beijing Blue Scarlet proposed the following suggestions to us:
1. When consumers purchase housing, they must not only look at the location, price, and structure, but also pay attention to understanding the house's indoor environment.
2. Select the formal decoration company and indicate the indoor environment requirements when signing the contract. In the decoration, try to use the interior decoration and decoration materials that meet the national standards.
3. The renovated house should not be immediately moved in, but there should be a certain amount of time for the harmful gases in the materials to be distributed with high intensity; maintaining the indoor air circulation, or opening the windows for ventilation when the outdoor air is good, is conducive to indoor harmful Gases are emitted and discharged.
4. The indoor environment testing experts can be asked to check the level of harmful gases in the indoor air so that appropriate control measures can be taken.
