Solid wood integrated floor
It is the use of advanced processing equipment to grow high-quality wood by finger jointing and hydraulic expansion. Maximize the rational use of resources. At the same time, the wood of different specifications is spliced ​​together so that the internal stresses are mutually depleted, so the deformation coefficient is relatively reduced. Moreover, after the floor is paved, there are fewer seams between the floors, which is especially suitable for a room with a large single room (such as a living room), and the overall effect is good. The product has undergone a rigorous boiling water stripping test (rigid requirements for the bonding strength and amount of glue).
Laminate floor
It is a floor made up of two or more layers in various ways. It has the advantages of good sound absorption (because its bottom sound absorbing material can absorb noise and impact resistance), good wear resistance and good flame retardancy. , no fading, easy maintenance and construction. It is good to stack the wood of several different materials in the upper, middle and lower layers, and then form them by hot pressing. The length is 1000mm-2500mm, the width is 180mm-190mm, and the thickness is 12mm-15mm.
Multi-layer solid wood flooring
That is, the solid wood composite floor is made of solid wood panels or veneers, the solid wood strip is the core layer, the veneer is made of the bottom layer, and the veneer is made of the veneer and the splint is used as the substrate. The name of the floor tree species is determined by the surface tree species.
The multi-layer solid wood floor is made of splint as the base material, and the surface layer is made of hardwood piece inlaid with jigsaw plate or sliced ​​thin wood. It is made of urea-formaldehyde resin, and there are many specifications for multi-layer solid wood flooring. At present, it is mainly sold in the market, which is the most popular three-ply five-layer solid wood floor. The specification is 910×125×18mm.
wooden floor
Also known as wood flooring, it has the advantages of no pollution, natural pattern, elegant weight, rich texture, and real elasticity. It is the preferred material for floor laying in home decoration. Its disadvantage is that it is not wear-resistant and loses its luster. Solid wood flooring has red oak, teak, gold ivory, eucalyptus, ash, cherry, maple and many other. Solid wood single floor is made of solid wood, which has strong selectivity for raw material size.
Laminate flooring
It is a kind of green floor, which is expressed by decorative paper or decorative laminate impregnated with melamine resin. The impregnated paper and laminate have protective coatings, which have good wear resistance and greatly improve the resistance of the material. Friction. The decoration usually prints the copied wood grain on the paper in advance. The bottom of the laminate wood floor has a layer of extruded paper. The decorative paper is printed on the substrate under pressure. The extruded paper and the coated plate are bonded to the substrate through the adhesive. together. Since the decorative grain is printed like natural wood grain, it retains the natural and primitive color, and is clearer and brighter than the original grain. In practical applications, the reinforced floor coating material is highly resistant to mechanical shock, and the smooth surface does not provide any living conditions for the mites. In addition, the laminate flooring does not need to be polished, lacquered or waxed. It can be wiped with a vacuum cleaner or a damp cloth or a mop. This also caters to the needs of modern people for a fast and easy and convenient lifestyle.
Less than 20% of the synthetic materials in the laminate flooring are used primarily in adhesives and coating materials. Although the urea and melamine resins in the binder carry methylamine, the final product can be converted to nitrogen and natural gas. The resin does not contain bio-corrosive substances, its structure and protein are similar, not only easy to decompose, but also can be used as a nitrogen fertilizer for green plants.
The indicators of wood chips and fibers used in the manufacture of reinforced flooring meet the needs of the panels used in furniture and home decoration, and are more resistant to moisture, without preservatives. To prevent the adhesive from hardening, chlorine-free chemicals are used.
Green core moisture-proof function
There are two main types of composite wood flooring substrates, one is particleboard, and the other is medium and high density board. It is made by crushing and grinding small diameter wood under high temperature and high pressure. It is now common. Among them, the density of medium density board is 550 kg-880 kg/m3, and the density of high density board is ≥880 kg/m3 or more. Foot line and area 1, the number of square meters of the floor used in the room floor / 2.4. 2, plus the loss of about 3-5% based on the actual use of the house. The final settlement of the project is based on the actual installed square meters.
Formaldehyde emission
Formaldehyde is a kind of chemical gas. When the content in the air reaches a certain concentration, it will cause harm to the human body. It is mainly used in the manufacturing process of composite materials to act as a bonding agent. The formaldehyde contained in the floor will not evaporate immediately, but will slowly evaporate due to different temperature and humidity conditions, and the volatilization time is more than ten years. Long-term living in an environment where the concentration of formaldehyde exceeds the standard, formaldehyde will cause obvious damage to the eyes, nose and respiratory system of people or cause skin diseases. Animal experiments have also shown that excessive formaldehyde release can also cause cancer of the nose and respiratory system.
Technical indicators
When purchasing composite wood flooring, the main technical indicators that should be understood are: 1. Wear index; 2. Impact resistance; 3. Resistance to stains and stains; 4. Resistance to smoke; 5. Wear of contact surfaces; , scratches on the casters of the chair; 7, volume expansion after water absorption; 8, formaldehyde emission.
Floor material stability
Floor stability includes flat dry shrinkage and flat warping of severe thermal warping. The former is a natural phenomenon caused by the swelling and shrinkage of the floor caused by weather changes; the latter is caused by abnormal use (such as sun exposure, water immersion, etc.) or quality. Homy Hongji floor is subject to strict anti-corrosion, anti-mite, anti-crack and other professional treatment, and has been supervised by the quality inspection department for a long time. Another: the higher the hardness of wood, the better the stability, such as heavy ant wood, teak and so on.
Macor Ceramic Structural Parts
Low-expansion and zero-expansion glass-ceramics are insensitive to temperature changes and can be used in applications where temperature changes but dimensional stability is required, such as housings for telescopes and lasers. The low expansion lithium-based glass ceramic is used for the fiber joint, and is more compatible with the Quartz Glass fiber in terms of thermal expansion coefficient and hardness than the zirconia material, and is easy to be precision processed and has good environmental stability.
