Mr. Zhang bought a large wood-like wardrobe and a writing desk in a large furniture market, and placed it in his master bedroom for less than two weeks. His body tickled inexplicably. When I went to the hospital for examination, I didn't find the reason. Later, after careful inquiry by the doctor, I found the crux: it was originally an allergic reaction caused by excessive formaldehyde in the furniture. Recently, the Municipal Consumers Association released a hotspot for indoor furniture pollution complaints, indicating that furniture emits harmful gases that cause the concentration of harmful substances in indoor air to far exceed normal standards. In this issue, we deliberately interviewed relevant experts to tell consumers how to choose a satisfactory wooden furniture. In the current furniture market, wood furniture has become a major product in the furniture category because of its bright colors, novel styles, and clear wood grain. Coupled with relatively moderate product prices, it is increasingly favored by consumers. Experts suggest that when consumers buy wooden furniture, they must first understand and master the identification technology of wooden furniture, which is an effective way to buy wooden furniture correctly. Focus on surface quality The wood-based furniture is based on wood-based panels such as particle board and medium-density fiberboard. The surface is decorated with melamine, PVC, wood veneer and paper wood grain. The wood-like pattern is clear and natural, smooth and smooth. , Has a good visual effect and feel. When buying furniture, it mainly depends on whether there are scratches, indentations, blisters, degumming and peeling and glue marks on the surface of the furniture materials. Focus on production quality In the production of wooden furniture , the formed plate is combined with decorative edge banding, cutting saws, and assembly of components. The quality of man-made panel furniture depends mainly on its sawing quality, edge and surface decoration quality and board port quality. In the cutting saw, the board has quality requirements for the verticality, straightness and angle of the plate components. Generally speaking, the cutting technology of the board meets the accuracy requirements within 0.01 millimeters per meter. Well, there will be no tilting of the plates after making the furniture. The decoration of the sides and faces mainly depends on whether the decorative parts are evenly coated, whether the bonding is firm, whether the trimming is smooth and smooth, whether the end faces of the visible parts such as the side panels, door panels, drawer panels, etc. are edge sealed. There is no trace of adhesion on the edge of the fine board. (Internship editor days) Â
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.
