Small knowledge of floor purchase

The real wood floor.

A) category

According to the processing degree, the real wood floor can be divided into:

1. Lacquer board, now more commonly used, the colour difference is small, the processing precision is high, environmental protection.

2. The plain board, which can be painted or waxed after being installed.

According to the oil characteristics of the floor can be divided into:

1. Oily floor

2. Non-oily floor, general oiliness is more stable than the non-oily floor.

2) size

Width: generally 50~150mm, 90mm more commonly used;

Thickness: above 18mm;

Length: generally 600mm, 900mm (more commonly used) 60 series and 500mm, 750mm 50 series.
3) key points

Texture: beautiful and generous, to remove clutter or flow;

Chromatic aberration: have the grain colour difference is normal, but unfavourable too serious;

Strength: high density, high strength, good stability and high price;

Drying: drying process is an extremely important process. It is best to dehumidify and dry at low-temperature heat pump.

Machining accuracy: the accuracy error of the thickness machining should be less than 0.5mm, the seam is tight, the gap is less than 0.2mm, and the square diagonal error is less than 1MM.

Crack: high-grade floor should not have the crack; The cracks in the middle and lower floors should not penetrate the texture.

Nodes with less than 3MM in diameter and less than 2MM in diameter and non-tight dead joints are not defective.

Tongue-and-groove: it should be close, straight, and the error of the project is not greater than 0.2mm.

Compound floor.

It is divided into the reinforced composite floor and solid wood composite floor.

1) strengthen the composite floor.

1) small knowledge

What is called wear-resisting layer: it is to be on the surface of aggrandizement floor is evenly pressed the wear-resisting agent of a layer of alumina.
2) purchasing points:

1. Wear-resisting value: the reinforced composite floor of the household, wear-resisting value is above 6000, the height of wear-resisting value is related to the content of aluminium trioxide and the thickness of the wear-resisting layer;

2. Planning: flat and complete;

3. Environmental protection: to strengthen the base of the composite floor is the density board, and the environmental protection products should be selected for the formaldehyde content;

4. Moisture-proof film: it must have an anti-alkaline substrate with a thickness of more than 0.2mm, and the pavement is a moisture-proof membrane that will not be less than 20CM in width.

5. Accessories system: mainly to kick the foot line and Angle line, and pay attention to the colour matching and strength of the floor.

2) solid wood composite floor.

1) key points

1. Specification thickness: the thicker the surface, the more wear-resistant, the European standard requires more than 4MM;

2. Material: the surface should be of a hard texture and beautiful texture. The core and bottom should be of soft and elastic varieties, and the varieties must be consistent to ensure their relative stability.

3. Machining accuracy: the solid wood composite floor is spliced closely, without the obvious difference;

4. Surface paint film: solid wood composite floor surface paint film USES UV curing, wear resistance good UV varnish;

5. Glue material: the solid wood composite floor is coated with formaldehyde binder, so it is necessary to choose environment-friendly products with low formaldehyde content when choosing.
