FIRE RETARDANT PLYWOOD VENEERS FOR LIUZHOU PLYWOOD:

1 decorative veneered fire retardant plywood is a kind of wood-based panel made of Natural Wood veneered on fire-resistant Plywood.

2 decorative veneered fire retardant plywood features:

Fire Retardant Veneer Plywood is one of the most commonly used materials for interior decoration. As the product surface decorative veneer is made of high-quality Wood by planing or peeling processing method, so than fire-retardant plywood has better decorative performance. The product is natural and simple, natural and noble, can create an intimate and elegant living environment.

3 types of Fire Retardant Veneer Veneer:

Decorative veneered fire retardant plywood according to the decorative surface can be divided into single-sided decorative veneered fire retardant plywood and double-sided decorative veneered fire retardant plywood; According to water resistance, it can be divided into class I decorative veneered fire retardant plywood, Class II decorative veneered fire retardant plywood and Class III decorative veneered fire retardant plywood According to the texture of decorative veneer can be divided into radial decorative veneer overlaid flame retardant plywood and chord decorative veneer overlaid flame retardant plywood. Common is single-sided decorative veneer veneer veneer veneer flame-retardant Plywood. Decorative veneer commonly used wood species are birch, Ash, Oak, water Qinggang, ELM, maple, Walnut and so on.

4 classification of decorative veneered fire retardant plywood:

The standard of fire retardant veneer plywood for decorative veneers in China stipulates that the fire retardant plywood for decorative veneers can be divided into three grades: First Class, first class and qualified. This reminds manufacturers and consumers are not in line with China's decorative veneer veneer flame-retardant plywood standards, such as some manufacturers mark grade "AAA" , which is an enterprise behavior.

5 National Standard for decorative veneered fire retardant plywood performance requirements:

China's current is the recommended standard GB / t 15104-94"decorative veneered wood-based panels" , the vast majority of enterprises in the production of the implementation of this standard. The Standard specifies the appearance quality, processing precision and physical and mechanical properties of veneer-faced fire-retardant Plywood. Its physical and mechanical properties are: Moisture content, surface bonding strength, dip stripping. GB 18580-2001"indoor decoration materials, wood-based panels and their products in formaldehyde emission limits" also stipulates the product formaldehyde emission limits.

1 The moisture content of fire-retardant veneered veneer is 6% ~ 14% according to the national standard.

2 The surface bonding strength reflects the bonding strength between the decorative veneer layer and the flame retardant plywood substrate. The National Standard stipulates that the index should be ≥50MPA, and the number of standard test pieces should be ≥80% . If this index is not qualified, the decorative veneer and the base material fire-retardant plywood gluing quality is poor, in the use of decorative veneer may cause the opening of the Glue Drum.

The results showed that the adhesive properties of the adhesive layers of the decorative veneered fire-retardant plywood were better than those of the decorative veneered plywood. This index is not qualified to explain the poor bonding quality of the plate, in the use of open glue may result.

4 formaldehyde emission limits. This indicator is a compulsory national standard implemented in our country on January 1,2002. It is the "birth permit" for related products. Products that do not meet this standard will not be allowed to be produced from January 1,2002. It is also the "market access permit" for related products, from 1 July 2002, products that do not meet this standard are not allowed to enter the market circulation area. Excessive formaldehyde will affect the health of consumers. According to the standard, the formaldehyde emission of the veneered fire-retardant plywood should be as follows: e 1≤1.5 mg / L, e 2≤5.0 mg / l.

Flame-retardant and flame-retardant products have the characteristics of small deformation, large size, good surface veneer effect, not easy to warp, high tensile strength of transverse grain, etc. , widely used in strict fire and flame retardant requirements of all types of public decoration, high-grade home decoration, high-grade furniture, high-speed emu cars, stadium, etc. .

FLAME RETARDANT PLYWOOD SUPERIOR PRODUCT PERFORMANCE:

1 EXCELLENT FLAME RETARDANCY: GB8624-2006 classification of fire performance of building materials and products, grade B GB / T8625-2005 test method for fire retardancy of building materials

(2) the free formaldehyde emission of the product is less than 4.0 mg / 100g, which is far lower than the national standard E1 grade 9.0 mg / 100g; (3) the moisture absorption of the fire-retardant plywood is not big, the expansion rate of the water absorption thickness is stable, the moisture-proof performance is excellent, does not affect the finishing, the paint and so on secondary processing; 4 with high chemical stability and excellent aging resistance, 5 Mor, Moe, IB and other physical and mechanical properties meet the requirements of the National Standard Grade A, 6 fire-retardant plywood is safe and environmentally friendly, burning Residues non-toxic, non-polluting; 7 fire-retardant Plywood Screw Grip Excellent, non-corrosive metal links; 8 do not damage the decorative properties of fire-retardant Plywood, adhesive and machining performance; 9 according to Customer Requirements for anti-mildew treatment; Product Specification: 12202440 mm flame-retardant wood-based panel as an important part of fire-fighting products should be carefully selected and purchased.
