In the constant pursuit of high-quality quality of life, modern people are paying more and more attention to energy conservation and environmental protection; health, low carbon, energy conservation, and environmental protection have become the mainstream trends in the world, especially in the capital, Beijing, where smog has appeared many times. More and more attention will be paid to environmental pollution. The glass used in many places will be replaced by acrylic. It is China's strategic policy to adhere to the path of sustainable development.
Low carbon, English is low carbon, which means lower (lower) greenhouse gas (carbon dioxide-based) emissions.
In the construction industry, Vanke’s “low-carbon community” is committed to low-carbon in all aspects: low-carbon energy, low-carbon buildings, low-carbon services, low-carbon consumption, realize the cycle of energy structure, and establish a zero-carbon in line with international green building standards Buildings. Vanke wants to achieve "low-carbonization" in all aspects. As a supporting industry, the sanitary ware industry must also meet the "low-carbonization" standards.
What kind of materials can meet Vanke's "low-carbon" standards?;
So far, the appropriate answer is: Acrylic;
Acrylic has lower energy consumption than ordinary glass, and acrylic is more environmentally friendly.
In fact, the glass industry has always been dubbed the "high-pollution industry", and some glass companies were once required to stop production because of excessive pollution. The pollution in the glass industry ranges from the extraction of raw materials, processing and transportation, to the production of harmful fumes from the combustion of fuels. The vast majority of glass industry furnaces use heavy oil as fuel, causing serious air pollutant emissions. According to preliminary estimates, the current total annual particulate matter emissions of the glass industry are about 12,000 tons, SO2 is about 160,000 tons, NOx is about 140,000 tons, HCl and HF are 4,000 tons and 1,200 tons respectively. Glass fumes come from three sources: A small part of the raw material is brought into the flue gas during the process.
Volatile substances (part of metal oxides, such as Na2O, etc.) in the furnace volatilize at high temperature and condense to form smoke; smoke and dust generated after fossil fuels. Nitrogen oxides in glass melting furnaces are produced by air combustion and the decomposition of a small amount of nitrate in glass raw materials. Since the flame temperature of the plate glass melting furnace is as high as 1650℃～2000℃, the nitrogen in the air will react with oxygen to generate a large amount of NOx. In addition, because the raw materials contain nitrates (generally KNO3), they decompose at high temperatures to produce part of NOx. Therefore, there is a large amount of NOx emissions in the flat glass flue gas, and the general concentration is as high as 2000mg/Nm3.
Acrylic does not have the above-mentioned pollution due to different manufacturing processes. It strictly abides by the pollutant discharge declaration system and has no emission reduction tasks. The pollutants generated are discharged up to standards after treatment. The industrial solid waste treatment and disposal rate is 100%. Environmental protection equipment is operating normally. The synchronous operation rate with the main equipment reaches more than 95%, and there is a sound environmental protection management organization and management system, and no heavy metal emissions.
Health, low carbon, energy saving, and environmental protection are the advantages of acrylic. This material itself does not worry about radiation (and is not within the scope of national mandatory testing and control) to protect human health.
