Technical Introduction of the Product
HPL is a decorative panel that comes in different sizes and thicknesses (2 to 25 mm). The HPL panel is made up of several layers of graphite paper. The layers of kraft paper and the top surface of the panel are impregnated with thermoset resins during production, and under high temperature and pressure, it becomes a dense light with an integrated structure. High durability and chemical resistance and fast and stable adhesion of consumable resins cause irreversible and unbreakable bonding of different layers of the panel. Among the uses of HPL panels in the construction industry, we can mention the implementation of dry facades, building interior walls, elevator decoration and construction of kitchen cabinets. The HPL panel is also widely used in other industries such as automotive and wagon manufacturing. HPL, which stands for High Pressure Laminate, is the name given to a combination of cellulose layers and phytic resins. After being placed at a temperature above 180 degrees and a pressure of 80 bar, this compound becomes a solid plate with special technical specifications. The final surfaces of these plates are covered with colored layers of resistant coating. HPL pages are widely used in a variety of fields. For interior and exterior coatings of buildings, it is common to use sheets with a thickness of 6-10 mm.
Attributes
HPL wood panels provide a wide range of facade design and other parts of the building, such as lobby walls, elevators, swimming pools, etc. Wood panel designs evoke the warmth of natural wood and bring the sense of nature to life in the viewer’s mind. Easy and fast installation, non-discoloration against UV rays, light weight, no need for maintenance, properties, anti-scratch and easy washing are some of the features of this product.
Resistance to atmospheric factors
HPL plates are resistant to sunlight, acid rain and moisture, and their color is well stabilized according to classifications 4 and 5 of the AΦ2Φ15-150 standard. A sudden change in temperature from -20C to 80C does not affect this thickness and the HPL view is stable against polluted air in large cities and the gases caused by environmental pollution do not change its appearance.
No need for constant washing
The non-porous surface and HPL’s electrostatic properties prevent it from clogging and staining the facade. Also, the chemicals used in regular cleaners have no effect on HPL.
Scratch resistance
The presence of a final melamine layer on HPL plates makes these plates resistant to scratches.
mechanical resistance
The combination of flexural strength and elasticity makes HPL sheets resistant to impact. Therefore, in the facade of the building, the surfaces react to various pressures from the wind pressure jacquard.
Fire
HPL sheets in Babur are fire resistant up to 160C and do not melt. They do not explode and do not self-ignite (Self Extinguish) and especially the gases produced by burning are dangerously low (Toxic).
Production Methods
This product is composed of a combination of cellulose layers and phenolic resin. The core of these panels is Kraft Paper layers, impregnated phenolic resin, an integrated decorative paper and enriched melamine resin, which is pressed in the upper deck and becomes the core of HPL sheet. The surfaces on these plates are covered with anti-scratch colored RTD layers, which are produced in the form of panels. HPL Uses Decorate the exterior and interior in a variety of colors.
- Electron Beam Curing
This process is designed to give the product a distinctive, durable and long-lasting appearance. This type of HPL is used for exterior and is resistant to acid rain.
- Dry Forming
In this process, natural elements are used, which include paper (solid brown paper and absorbent paper) with wood chips. The absorption of resin by wood tissues and heating under high pressure to form a wicker texture is called Dry Forming.
Uses
Office and industrial spaces
Stadiums
Hospitals
Public health services
Interior and exterior of buildings
