How much does the national standard require the thickness deviation of aluminum veneer

The national standard requires aluminum veneer.

The thickness deviation is not less than.

The structure of aluminum veneer is mainly composed of panels and stiffeners.

and corner code and other components.

The maximum workpiece size can reach 8000mm, and the 1800mm (L W) coating adopts the United States PPG, the United States Valspar, and the Netherlands AkzoNobel.

Akzonobel, South Korea KCC, and other well-known brand coatings, the coating is divided into two coatings and one baking, three coatings and two baking, and its coating performance has reached the AAMA (American Building Manufacturing Association) and ASCA (American Building Spraying Association) AAMA2605 98 standard.

Regular thickness:.

Common specifications: 600*600mm, 600*1200mm<>

The nominal thickness of the aluminum veneer substrate (excluding the coating) for outdoor use should not be less than, and the nominal thickness of the aluminum veneer substrate for indoor use (excluding the coating) shall be agreed upon by the supply and demand parties.

Aluminum veneer refers to the building decoration material formed by chromization and other treatments, and then processed by fluorocarbon spraying technology. Fluorocarbon coatings mainly refer to polyvinylidene fluoride resin (kanar500), which are divided into three types: primer, topcoat and varnish.

The spraying process is generally divided into two, three or four coats. Fluorocarbon coating has excellent corrosion resistance and weather resistance, can resist acid rain, salt spray and various air pollutants, has excellent cold and heat resistance, can resist strong ultraviolet radiation, can maintain long-term non-fading, non-chalking, and long service life.

Different plate thicknesses have different standards, generally according to plus or minus! You have to refer to the national standards for details, and there is a lot of information on this network!

White aluminum veneer on the background wall of the front desk.

The standard thickness of aluminum veneer is: surface treatment: fluorocarbon spraying, polyester spraying This is the standard answer, if you want to do something like that, you need to customize.

Thickness standards for aluminum veneer: ceilings, curtain walls; And the thicker is not the better, but the width of the board and the weight of the plate itself should be considered.

First of all, the curtain wall aluminum veneer is made of high-quality aluminum alloy plate as the base material, which is formed by CNC bending and other technologies of building materials, and the surface is sprayed with fluorocarbon, paint and other decorative coatings.

The thickness of the commonly used curtain wall aluminum veneer is ,,, there are a small number of specifications used by users on the market, and the model of the curtain wall aluminum veneer is H24.

Secondly, curtain wall aluminum veneer is often used for outdoor and indoor decoration, outdoor can be applied to building exterior walls, indoor can be used for interior wall decoration. The curtain wall aluminum veneer is light in weight, strong in hardness, simple and atmospheric in style, not only practical, but also beautiful.

Nowadays, most buildings use this material to do exterior wall or interior decoration, the material is used for a long time, the rate is very high, it can be called an environmentally friendly green building material, and it is very suitable for all kinds of buildings.

The nominal thickness of the aluminum veneer substrate (excluding the coating) for outdoor use should not be less than, and the nominal thickness of the aluminum veneer substrate for indoor use (excluding the coating) shall be agreed upon by the supply and demand parties", see the following national standards for details:

GB T 23443-2009 Aluminum veneer for building decoration JG T 331-2011 Fluorocarbon aluminum veneer products for building curtain walls (implemented on February 1, 2012).

YS T Aluminum Curtain Wall Panel Fluorocarbon painted aluminum veneer.

Thickness: Surface treatment: fluorocarbon spraying, polyester spraying.

According to the standard in GB T "Aluminium and Aluminum Alloy Plates and Strips for General Industrial Use Part 3: Dimensional Deviation", the allowable deviation of 2mm aluminum sheet needs to be determined according to the width of the plate:

Width (mm) Allowable deviation of thickness (mm).

3) Lu Xincha 800 1000

The thickness tolerance of the national standard thin aluminum plate is within 5 wires (thin aluminum plate refers to the plate with a thickness of less than 4mm).

The thickness tolerance of the national standard thick aluminum plate is within plus or minus 10 wires (thick aluminum plate refers to the plate with a thickness of more than 4mm).

Aluminum sheet is an aluminum sheet with a thickness of more than 500mm, a width of more than 200mm, and a length of less than 16m.

Or aluminum sheets, the following are aluminum, and the width of 200mm is row or strip (of course, with the progress of large equipment, the widest aluminum plate can be 600mm).

with aluminum ingots. The rectangular plate made by rolling is divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, medium thick aluminum plate, and flower friend stool pattern aluminum plate.

Extended information: The manufacturing process of repeatedly scraping aluminum plates out of lines with sandpaper, the main process is divided into three parts: deesterification, sandmill and washing. In the aluminum plate drawing process, the special film technology after anodic treatment can make the surface of the aluminum plate form a film layer containing the metal component, and clearly show every fine trace, so that the metal is matte.

Dense hair shine.

Place the aluminum plate in the corresponding electrolyte.

Such as sulfuric acid, chromic acid, oxalic acid.

etc.), as an anode, under specific conditions and impressed current, electrolysis to form an aluminum plate. The aluminum plate of the anode oxidizes and alumina forms on the surface.

Thin layer, the thickness of which is 5 good crack brigade 20 microns , hard anodized film up to 60 200 microns .

The thickness of the aluminum plate is 3 mm, and the thickness error standard is allowed between *, see GB T Table 3 for details.

The allowable deviation of the thickness of the aluminum plate is in the Chinese national standardgb/"General industrial aluminum and aluminum alloy plates, strips pre-configuration Part 3:Dimensional deviationThere are clear provisions:

1. When the width of the aluminum plate is less than or equal to 1000 mm.

The allowable error of the thickness of Class A aluminum plate is plus or minus millimeters, and the allowable error of the thickness dust scale of Class B aluminum plate is plus or minus millimeters.

2. When the width of the aluminum plate is greater than 1000 mm and less than 1600 mm.

The allowable error of the thickness of Class A aluminum plate is plus or minus millimeters, and the allowable error of the thickness of Class B aluminum plate is plus or minus millimeters.

3. Brother Hui refers to when the width of the aluminum plate is greater than 1600 mm and less than 2000 mm.

The allowable error of the thickness of Class A aluminum plate is plus or minus millimeters, and the allowable error of the thickness of Class B aluminum plate is plus or minus millimeters.

4. When the width of the aluminum plate is greater than 2000 mm and less than 2500 mm.

The allowable error of the thickness of Class A aluminum plate is plus or minus millimeters, and the allowable error of the thickness of Class B aluminum plate is plus or minus millimeters.

5. When the width of the aluminum plate is greater than 2500 mm.

The allowable error of all types of aluminum plate thickness is plus or minus millimeters.
