UPVC Window is rapidly marketing and popularized in the engineering and construction industry with its excellent environmental protection and energy saving practical effects. As a "low-carbon and environmentally friendly" product, it is increasingly favored by many customers. As everyone knows, environmental protection and energy saving do not mean environmental protection. Toxic plastic steel doors and windows not only pollute the environment, but also endanger health. So how to choose UPVC Window?
1. Look at the packaging logo
Look at the product name, national standard, company name, place of production, quality grade, etc. on the packaging design or label. If the basic content indicates whether it is complete, whether there is overlap or error in the overprinting of the text or pattern design. If the content of the packaging logo is incomplete, the text or graphic design and printing have overlaps or errors, it must be produced by a small and medium-sized profile company, and it is best not to purchase.
2. Look at the color of the product
The color of the toxic UPVC Window is white. Although it is white, it gives people a "stunned" visualization, that is, it is dark or white and blue, and the smooth feeling is obvious. After a period of application, it is polluted by the sulfur and sulfate in the air. Gradually dark gray. The color of the non-toxic plastic steel profile is authentic, like ivory, with a smooth feeling, translucent, bright and gentle. It feels like it penetrates into it, and it will not appear dark gray when it is polluted by the sulfur and sulfate in the air.
3. Look at the actual effect of the application
Under the long-term effects of sunlight and heat, lead-salt UPVC Window produces lead smoke and dust on the surface, which can cause lead poisoning symptoms and lead environmental pollution. After lead enters the body, except a part of it is excreted in excrement and sweat, most of it is deposited in the spinal cord and melted into the night of blood, harming the software of the hematopoietic system and the central nervous system of the human brain. Lead can also block blood production in the human body, causing iron deficiency anemia, causing headaches, dizziness, drowsiness, drowsiness, severe constipation and body aches. Application of organotin UPVC Window is not prone to the above symptoms.
4. See the quality inspection confirmation
After selecting the UPVC Window, be sure to ask the agent for the product quality inspection certification. If the new test item in the certificate or test report is marked with lead content, it is confirmed that the product is a PVC profile.
5. Look at the name of the product profile
Toxic UPVC Window generally uses high-quality and low-cost lead salt thickener as the key raw material. This type of raw material contains lead content, and the name is "PVC profile". Non-toxic UPVC Window uses non-toxic, zero-pollution, carbon alcohol organotin T-137 thickener, which is in compliance with environmental protection regulations, and the name is "VPVC profile".
