Theoretically speaking , after special processing , as long as the manufacturer is formal , the aluminum alloy doors and windows produced have no toxic substances. , if you find peculiar smell when purchasing , then it is best to change the doors and windows of another brand to have a look , select some famous big brands , quality and other aspects should be more guaranteed , recommend look at Yihe doors and windows, royal doors and windows, Yibo doors and windows, and fixed doors and windows. , these are good doors and windows enterprises. .
Aluminum alloy doors and windows are harmless to health. Although people absorb excess aluminum is harmful to health , but what human body absorbs is that aluminum in ionic state cannot absorb aluminum in elemental state. Aluminum alloy doors and windows are made of simple aluminum , therefore, it is harmless to health.
First, look at the product profile name. Toxic plastic steel doors and windows generally use low-cost lead salt stabilizer as the main raw material. This raw material contains lead , the name is PVC profile ". Non-toxic plastic steel doors and windows adopt non-toxic and pollution-free thiol organo tin T-137 stabilizer that meets environmental protection requirements , the name is VPVC profile ".
Second, look at the packaging logo. Look at the product name, Implementation Standard, factory name, factory address, quality grade, etc. marked on the product packaging or attached label. For example, whether the basic content is marked completely , whether the color of the text or pattern has ghost or deviation. If the package logo is incomplete , text or pattern overprint with double image or deviation , it must be produced by small profile Enterprises , it is better not to buy it.
Third, look at the quality inspection certificate. After selecting plastic steel doors and windows, you must ask the distributor for the product quality inspection certificate. If the inspection items of the certificate or inspection report are marked with lead components , prove that the product is PVC profile.
Fourth, look at the color of the product. Toxic plastic steel doors and windows color White , although White , but the intuitive feeling is very "stunned" , that is, it is dark or white and transparent blue , strong sense of smoothness , after using for a period of time, it is gradually gray-black due to pollution by sulfur and sulfide in the atmosphere. Non-toxic plastic steel color pure , ivory White , bright and clean, crystal clear and soft , it feels like penetrating inside , pollution by sulfur and sulfide in the atmosphere will not appear gray and black.
Fifth, see the use effect. Lead salt plastic steel doors and windows under long-term sunlight and heat , lead dust formed on the surface , it will cause lead poisoning and lead pollution. After lead enters the human body , the Except part is discharged through feces and sweat. , most of the precipitation in bone marrow , dissolve into blood , damage bone marrow hematopoietic system, brain nervous system, urinary system and reproductive organs, etc. Lead can also hinder human blood synthesis , cause anemia , symptoms such as headache, dizziness, fatigue, drowsiness, constipation and aching limbs appear. The above symptoms will not occur when organic tin plastic steel doors and windows are used.
Of course, powder spraying on some doors and windows is a new coating material with powder and no liquid solvent diluent. , heavy corrosion resistance, powder recycling, high decorative , features such as no pollution to the environment. In the whole spraying process , the chemical composition of powder coating has not been changed , just using physical methods to heat the environmentally friendly powder coating on the surface of aluminum , therefore, no formaldehyde is produced in the whole material, coating and process. , of course, don't worry about whether it is poisonous.
