The fire accident caused by the window cloth is often present in life, and it always hurts people to mention it. The prices of curtain fabrics vary greatly from 20-30 to 100%, but it is difficult for us to find a real window cloth that can be fire-retardant. The following small series for everyone to introduce what is the performance of flame retardant curtains and flame retardant curtains. What is a flame retardant curtain Flame-retardant curtains are actually curtains made of flame-retardant fabrics. The curtains of fabrics can achieve the effect of fire prevention and disaster reduction. The Chinese National Standard GB50222-95 "Fire Protection Code for Interior Design of Buildings" stipulates that decorative materials are divided into four according to their burning performance. Grade: A grade is non-flammable; B1 grade is non-flammable; B2 grade is flammable; B3 grade is flammable. Therefore, as long as the A-level and B1-level fabrics can be called flame-retardant fabrics. At present, except for non-textile fabrics that can achieve Class A flame retardancy, the highest class of flame-retardant fabrics is Class B1. Flame-retardant curtain performance 1. Fire protection level: M1, B1 level up to GB/T5455-1977 standard. 2. Environmental protection standards: GB50325-2001, the chemical composition of the fabric can not exceed the relevant standards and specifications issued by the country. 3. The content of harmful substances in the flame-retardant curtain fabric conforms to GB1840-2003 National Basic Technical Specifications for Textile Products. 4. Fire protection standards: GB/T5455-1997 5, process: anti-oil stain, dirt, easy to clean, anti-pollution, anti-mildew, easy to hide dirt, soft colors, anti-distortion treatment. 6, effect, performance: no wrinkle, no fading, sun color fastness 5-6, no odor. 7, formaldehyde content: There are national standards E1 emission standards, and PVC-coated polyester fiber as a raw material carefully weaved products, absolutely not containing glass fiber components. Classification of flame-retardant curtains 1. Permanent flame-retardant curtains are made of permanent flame-retardant fabrics combined with modern special process curtains. 2. Disposable flame-retardant curtains are curtains made of disposable flame-retardant fabrics as raw materials. 3, nano-flame retardant curtains can achieve flame-retardant, heat insulation, sound insulation, antibacterial, mold, waterproof and other functions of curtain fabric. Editor's summary: The performance of flame-retardant curtains and flame-retardant curtains is introduced here. Hopefully everyone will be helpful.

A Noise Barrier (also called a soundwall, sound berm, Sound Barrier, or acoustical barrier) is an exterior structure designed to protect inhabitants of sensitive land use areas from noise pollution. Noise barriers are the most effective method of mitigating roadway, railway, and industrial noise sources – other than cessation of the source activity or use of source controls.
