Energy-saving does not mean that environmental protection, toxic plastic steel doors and windows (decoration renderings) not only pollute the environment, but also damage human health. In recent years, plastic steel doors and windows have been rapidly popularized in the field of construction engineering with its good energy-saving effect. As a "green environmental protection" product, it is increasingly favored by users.
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. Look at the product profile name. Poison-plastic steel doors and windows generally use low-cost lead and salt stabilizers 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 packaging logo. Look at the product name, implementation standard, factory name, site, quality grade, etc. marked 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.

Look at the product color. The toxic plastic steel doors and windows are white in color, although they are white, but they give people an intuitive feeling that they are "squeaky", that is, they are dark or white in blue, and the sense of cleanness is very strong. After being used for a period of time, they are gradually grayed by sulfur and sulfur compounds in the atmosphere. 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.
See the effect of use. Lead and salt-type plastic steel doors and windows under the long-term effect of sunlight and heat, the formation of lead dust on the surface, will lead to 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.
