1 How to distinguish toxic steel doors and windows In recent years, plastic doors and windows with its good energy-saving effect in the field of construction engineering quickly popularized, as a "green" products, more and more favored by the majority of users. However, energy conservation does not mean environmental protection. Toxic plastic steel doors and windows not only pollute the environment, but also harm human health.
In order to protect consumers from toxic steel doors and windows, here are some simple ways to judge whether or not the plastic doors and windows are poisonous.
To see the product profile name toxic steel doors and windows generally low-cost lead and salt stabilizer as the main raw material. This raw material contains lead and its name is "PVC profile". Non-toxic plastic steel doors and windows use non-toxic, non-polluting, environmentally-friendly thiol organotin tin T-137 stabilizer, named "VPVC profiles."
Look at the package label to see the product name, implementation standard, factory name, site, and quality grade as indicated on the product package or label. If the basic content is complete, whether there is ghosting or deviation in the text or pattern registration. If the content of the packaging label is incomplete, there is ghosting or deviation in the overprinting of the text or pattern. It is definitely a small-sized production company, and it is best not to buy it.
Look at the quality inspection to prove that after choosing a good steel doors and windows, be sure to ask the dealer for a product quality inspection certificate. If the inspection target of the certificate or inspection report has a lead component, it proves that the product is a PVC profile.
Look at the product color toxic steel doors and windows white color, although white, but gives the intuitive feeling is very "squeaky", that was dark or white in the blue, a very strong sense of cleanness, after a period of time due to sulfur and sulfide pollution from the atmosphere Gradually grayish black. The non-toxic plastic steel is of pure color, which resembles ivory, and its smoothness is crystal clear and soft. It has the feeling of permeating into the inside, and it will not be grayish black when polluted by sulfur and sulfur in the atmosphere.
Look at the use of lead and salt steel doors and windows under the long-term effects of sunlight and heat, the surface of lead dust, lead poisoning and lead pollution. After lead enters the human body, except for some that are excreted in feces and sweat, most of them precipitate in the bone marrow and melt into the blood, damaging the bone marrow hematopoietic system, the brain's nervous system and the urinary system and reproductive organs. Lead can also hinder human blood synthesis, resulting in anemia, headaches, dizziness, fatigue, drowsiness, constipation and body aches and other symptoms. The use of organic tin steel doors and windows will not appear the above symptoms.

At present, many family doors and windows and packaged balcony materials are made of various aluminum alloy profiles. Therefore, when you purchase, we must look at how the quality of raw materials. In general, visual inspection can also make a preliminary assessment of the quality of aluminum profiles, the main methods of identification are as follows:
1. Check whether the profile thickness of the profile is consistent with the model, and profiles that cannot reach the wall thickness cannot be used.
2. Check whether the aluminum alloy profile (6 meters long) has obvious twisting and twisting. If the twist is severe enough to be difficult to recover, it cannot be used anymore.
3. Check whether the surface of the profile is flat; whether there is white spots, black spots; whether there are cracks, burrs, peeling; whether there are obvious scratches, bumps and so on.
4. The same aluminum alloy profile is not allowed to have different shades of color; put several profiles together, the color difference should not be used.
5. The surface of the profile, gently scratched with a smooth hard object, will leave a white mark. If it can be wiped off by hand, the oxide film is not scratched off; if it cannot be wiped off by hand, it means that the oxide film has been scraped off and the quality of the material is problematic.
