Let the interior environment become green, low-carbon, and the air quality control standards that the majority of consumers look forward to for years are finally settled. The Ministry of Environmental Protection and the State General Administration of Quality Supervision, Inspection and Quarantine jointly issued the Guidelines for the Evaluation of Air Quality in Passenger Cars, GB/T27630-2011, which will be formally implemented on March 1 next year.
Secretary General of the China Indoor Environment Monitoring Committee, the Director of the National Indoor Environment Monitoring Working Committee, and the director of the National Indoor Environment and Indoor Environmental Quality Inspection Center, which first proposed domestic environmental pollution in the country, recently told reporters that the standard is to promote the green and low-carbon environment of China's auto industry. The development of a progressive normative document is meaningful and far-reaching.
More than 90% of vehicles have pollution problems While people are fully enjoying the pleasure of driving, they do not know that they are accompanied by the "invisible killer" of air pollution in the car for a long time. It is understood that the city of Guangzhou conducted a seven-month in-vehicle air quality inspection on 2,000 vehicles. The result showed that 92.5% of vehicles had air quality problems in the vehicle. In response to the ongoing car pollution incidents, the China Interior Decoration Association's In-vehicle Environmental Monitoring Center issued the first number of in-vehicle environmental consumption warnings in 2004: alert to the new vehicle interior air pollution.
According to Song Guangsheng, compared with the indoor environment, the space and environment inside the vehicle are more narrow and more confined. For example, after long-distance driving in the summer, when the materials in the vehicle are exposed to sunlight under long-term sun exposure, harmful substances are volatilized and the concentration may increase. Times, and consumers continue to stay in a small and confined environment for several hours, the harm of harmful substances to the human body is self-evident. According to survey statistics, about 65% of drivers have dizziness, drowsiness, and coughing due to environmental pollution in the vehicle while driving. In-vehicle air pollution has become the main cause of driver's feelings of depression, irritability and inability to concentrate. one of the reasons. The China Indoor Decoration Association Indoor Environment Monitoring Center conducted 100 new car tests in the Beijing area and found that the pollution problem in the new car was as high as 90%. Because China does not have pollution control standards for the interior environment, these surveys basically use the relevant standards of the indoor environment.
The new standard has triggered the attention of the society to the Guidelines for the Evaluation of Air Quality in Passenger Cars to be implemented next year. Based on the analysis of the types and sources of volatile organic compounds in the air in the vehicle and the analysis of the volatilization characteristics of the main interior materials of the vehicle, eight main types have been identified. The substances to be controlled stipulate the concentration requirements of benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, and acrolein in the air in the vehicle. Song Guangsheng analyzed that the implementation of this guideline has very important practical significance and far-reaching historical significance for promoting the development of green and low-carbon environmental protection in China's automobile industry and the protection of consumers' rights and interests.
At present, due to various reasons, relative to the indoor environment pollution, the problem of environmental pollution in the car has not attracted the attention of the whole society. Solving the problem of environmental pollution in the car has not attracted sufficient attention. Song Guangsheng said that the implementation of this guide can further increase the attention of the whole society to the air quality problem in the car, and improve the air quality in the car and protect the health of drivers and occupants, including the relevant government departments, industry management departments, and automobiles. The consensus of the entire society, including R&D, production, sales, and auto material interiors.
It is reported that the problem of air pollution in new vehicles is closely related to automobile production processes and materials. In recent years, some foreign manufacturers have attached great importance to the chemical pollution and even odor pollution of materials released. China is still in the process of research, and individual companies are trying to reduce production costs. The use of contaminated adhesives, damping sheets and other contaminated materials has become a major problem of air pollution in vehicles. The publication and implementation of this guideline can effectively improve the selection and control of materials by automotive manufacturers.
Providing supervision basis for quality supervision authorities In recent years, due to the lack of in-car air quality assessment standards, the frequent occurrence of in-car air quality problems has affected consumers' confidence in the government's supervision and management of automobile quality. The implementation of this guide can provide scientific standards and evidence for air quality supervision and inspection in automobiles, and provide the basis for normative supervision and inspection for quality supervision departments at all levels. In addition, it can also strengthen China's control of the air quality of imported cars. In recent years, China’s auto imports have increased year by year. At the same time, the in-vehicle environmental pollution of imported cars is also one of the major issues affecting consumer health and rights protection. In recent years, the National Indoor Environmental Quality Inspection Center has accepted a number of complaints about the air quality of imported high-grade automobiles, but it is often difficult to handle due to lack of legal regulatory documents.
Song Guangsheng said that although the "Guidebook for Assessment of Air Quality in Passenger Cars" is currently a recommended national standard, according to the requirements of national standards, the recommended standards are accepted and adopted, or the parties agree to agree to be included in the economic contract or The introduction of laws and regulations has become a technical basis that all parties must jointly abide by, and it is legally binding. The recommended standards cited in economic contracts must be implemented within the scope of the contract. The first case of indoor formaldehyde pollution in China is the recommended standard.
At the same time, the standard can also promote the development of air quality control technologies and product industries. It is understood that solving the problem of environmental pollution in cars has become an important aspect of the development of China's indoor environmental protection industry. A large number of service companies specializing in in-car air purifiers, purifying materials, and solving environmental pollution problems in cars have emerged. Physical, chemical and biological methods can effectively control the environmental pollution in the vehicle. The publication and implementation of this guideline can promote the further development of the air purification industry in China and provide efficient services for solving the environmental pollution problems in the vehicle.
The main source of air pollution in the car is the various accessories in the new car. The first category is seats. Including seat cushions, seat backs, seat covers and seat fabrics, headrests and other materials in the car seats; the second category is interiors. Including the interior floor, interior door guard, side wall guard, back wall guard, roof lining, curtains, floor coverings, etc.; the third category is the functional category. Including body insulation materials, collision packing, instrument panel, glove box, interior shelf plate or back window plate, sun visor, wheel cover cover, hood cover and so on.
The second is from the automotive interior materials, including automotive interior parts made of a single material or composite material, organic materials, mainly plastics, fiber textiles, leather, rubber and other four major categories of materials.
The third is solvent-based paints, thinners, and glue paints and coatings used in production. The use of solvent-based paints on the one hand increases the pollution of volatile organic compounds in the vehicle and atmosphere. On the other hand, due to the increase in automotive interiors, various adhesives and organic solvents, auxiliaries, and additives have been widely used. According to investigations, the amount of adhesive used in a family car currently exceeds 5 kg and the highest can reach 27%. kg.

Shaping machine is a machine designed for giving desired shapes to the surfaces that may be horizontal, vertical and flat. A shaping tool is used to cut in curves, different angles, and many other shapes. A disc is responsible for the tool rotation which results in the forward and backward movement. The cutting tool is used to give the shape to the hard surface of metal or wood by removing the excess material.
The shaping machine operates in the reciprocating type of machine function. Here the work piece is fixed on the machine table and the cutting tool is placed on the work piece. Reciprocating movements over the work piece results in forward and backward strokes. Forward stroke is responsible for cutting action over the object and backward movement is responsible for restoring its position without any cutting action.
