I. structure of plastic steel doors and windows. Plastic steel doors and windows are mainly made of unplasticized polyvinyl chloride (PVC) plastic profiles in western languages, plus hardware. The profile is a porous cavity, and the main cavity is lined with steel made of cold rolled steel plate to improve the strength of plastic steel doors and windows. The wall thickness of the profile shall be more than 2.5mm

II. Manufacturing of plastic steel doors and windows. Plastic steel doors and windows are generally manufactured in factories with special cutting and welding equipment for plastic steel doors and windows. They are semi-automatic and automatic production, and the quality can be guaranteed

III. precautions for the purchase of plastic steel doors and windows

plastic steel doors and windows are rapidly popularized in the field of Construction Engineering with their good energy-saving effect, as “ Green environmental protection ” Products, more and more favored by the majority of users. However, energy conservation is not equal to environmental protection. Toxic plastic steel doors and windows not only pollute the environment, but also damage human health

five methods to identify toxic plastic steel doors and windows:

first, look at the package identification

look at the product name, executive standard, factory name, factory address, quality grade, etc. marked on the product package or label. For example, whether the basic content labels are complete, and whether there is ghosting or deviation in the text or pattern coloring. If the content of the package logo is incomplete, and the words or patterns are overprinted with ghosting or deviation, it must be produced by small profile enterprises, and it is best not to buy it

second, look at the product color

the color of toxic plastic steel doors and windows is white. Although it is white, it gives people a very intuitive feeling “ Leng ”, It is dark or blue in white, with a strong sense of smoothness. After a period of use, it gradually turns gray black due to sulfur and sulfide pollution in the atmosphere. The color of non-toxic plastic steel is pure, ivory white, bright and clean, crystal clear and soft, with the feeling of penetrating into it. It will not be gray black if polluted by sulfur and sulfide in the atmosphere

III. see the effect of use

lead salt plastic steel doors and windows form lead dust on the surface under the long-term action of sunlight and heat, which will cause lead poisoning and lead pollution. After lead enters the human body, except for some excretion through feces and sweat, most of it precipitates in bone marrow and dissolves into blood, damaging bone marrow hematopoietic system, brain nervous system, urinary system and reproductive organs. Lead can also hinder human blood synthesis, leading to anemia, headache, dizziness, fatigue, sleepiness, constipation, limb pain and other symptoms. Using organic tin plastic steel doors and windows will not have the above symptoms

IV. look at the quality inspection certificate

after selecting plastic steel doors and windows, be sure to ask the dealer for the product quality inspection certificate. If the inspection item target in the certificate or inspection report has lead composition, it is proved that the product is PVC profile

v. look at the product profile name

toxic plastic steel doors and windows are generally made of low-cost lead salt stabilizers. This raw material contains lead, and its name is “ PVC profile ”. Non toxic plastic steel doors and windows adopt mercaptan organotin t-137 stabilizer, which is non-toxic, pollution-free and meets environmental protection requirements, with the name of “ VPVC profile &rdquo
