The new standard of upholstered furniture will increase the requirements for environmental performance such as formaldehyde and azo.
Â
According to Luo Xin, executive deputy director of the National Furniture and Indoor Environmental Quality Supervision and Inspection Center, there are currently three main types of people entrusted to the center for furniture testing: furniture manufacturers, sales companies, and consumers. Generally speaking, due to the high temperature and humidity in summer and the rapid release of gas, consumers entrust more inspections.
Â
Luo Xin introduced that this summer the center has accepted more than a dozen consumer furniture testing projects entrusted by consumers. After testing, about 60% are qualified products and 40% are unqualified. The unqualified problem mainly occurs in formaldehyde exceeding the standard, cracking and deformation, etc., and the products in question are mainly concentrated in the building materials city in the remote suburbs or the furniture purchased from small enterprises.

It is understood that at present, furniture testing is charged per piece, and the cost of each piece of furniture testing is about 500 yuan. The detection method is to sample separately according to the different material composition, and then put the sample into standard air for extraction and analysis.

Industrial sectional doors are the most durable and longest lasting doors to ensure circulation at the areas of the factory entrance and exit of goods, loading and unloading areas.
The body of sectional door is forming by 40 mm sandwich panels. These panels provides sound and heat insulation due to the intense doped polyurethane insulation was injected between galvanized steel sheet. (50 kg/m3).
Industrial sectional door systems provide space-saving with opening parallel to the ceiling.Any opening can be used clearly . and produces in accordance with the transition range and the height in the factory buildings or warehouses.
Doors is working sliding by be the most appropriate the gap between the top level of the gate with a ceiling height within the side rasils. The door can be mounted in different ways according to the gap distance (standard, low, highlift and vertical track systems).
Industrial sectional doors can easily be opened automaticly by 230-380 V-AC/50 Hz electric motor or manualy thanks to torsion spring system that balances the weight of the door.The galvanized springs are made to be durable of 25.000 door cycles.Motor with emergency chain All the drive systems have a mechanical back-up system fitted to the reduction gearbox of the electric motor, so that the sectional door can be opened if the power fails. The reduction gearbox can then be powered using the chain.
