What are the advantages of cork? What is softwood

Wood is not wood, creating a comfortable cork life. The characteristics of cork that I know are: green and environmentally friendly, comfortable, high wear resistance, good sealing, sound insulation, heat preservation, vibration damping. In particular, cork flooring is not only comfortable but also tasteful at home!

There are many kinds of cork, made into furniture, ** on which most people can accept. Many corks are also used in combination with hardwoods. For example, beech, nanmu, camphor, pine and fir are all common cork materials.

1. Black walnut, walnut is a kind of wood quality, mainly produced in North America and Europe. Domestic walnut with a lighter color. The black walnut is light black-brown with purple color, and the chord section is a beautiful large parabolic pattern (large mountain pattern).

Black walnut is very expensive, and furniture is usually made with veneer and rarely with solid wood.

2. Cherry, imported cherry wood is mainly produced in Europe and North America, the wood is light yellow-brown, the texture is elegant, the chord section is a medium parabolic pattern, and there are small circles between them. Cherry wood is also wood, and veneer is usually used for furniture, and solid wood is rarely used.

3. Beech, the beech here refers to beech, which is different from the beech wood of "South Beech and North Elm" in traditional Chinese furniture. The beech wood is bright and light yellow in color, with dense "needles" (wood rays) and rotary cut with mountain lines. Imported beech from Europe has fewer defects and is much better than domestic ones.

Imported beech wood belongs to the medium wood in China, commonly used wood veneer, solid wood is also used as dining chairs and small square strips.

4. Maple, maple is light yellow in color, with small mountain lines, and is characterized by "shadow" (obvious local luster). Maple is a mid-range wood, and both veneer and solid wood are common.

5. Birch, birch is light yellow in color, and it is easy to distinguish with many "waterlines" (black lines). Birch is also a mid-range wood, with both solid wood and veneer common.

6. Rubber wood, native to Brazil, Malaysia, Thailand, etc. It is produced in Yunnan, Hainan and coastal areas in China, and is the raw material of latex. The color of rubberwood is light yellowish-brown, with messy small rays, obvious annual rings, dark bands at the ring boundary, and few tube holes.

The wooden structure is coarse and uniform. The grain is oblique and the wood is hard. Pros:

The cutting surface is smooth, easy to glue, and the paint coating performance is good. Disadvantages: Rubber wood has a peculiar smell, because of the sugar content, easy to change color, decay and insect eaten.

It is not easy to dry, not wear-resistant, easy to crack, easy to bend and deform, easy to process wood, and easy to deform when processing plates.

7. Oak wood, the material is heavy and hard, the structure is coarse, the wood ray is obvious, the mechanical strength is high, the wood is not easy to dry, the processing is difficult, the damage resistance, the cementation is not easy, but the coloring performance is good, the bending performance is very good, and it is often used as the surface material of furniture and thin wood veneer.

8. Pine, no need to carve, clear texture, delicate lines. It has a pine scent and has a beautiful scar. The production process is demanding and requires drying and degreasing.

9. Catalpa, the wood is shiny, the structure is slightly coarse, the drying speed is slow, it is not easy to warp, it is easy to process, and it is nailed.

10.Oak and beech can be used to make beds, TV cabinets, coffee tables, folding tables and camphor pine, fir wood is relatively soft, relatively cheap, and the disadvantage is that it is easy to deform!

There are many types of natural wood, and the texture, texture, and water absorption of wood vary from region to region and environment. According to the characteristics of wood processing, we divide these woods into hardwoods and softwoods.

1.Hardwood. Hardwood is taken from broad-leaved trees, the straight part of the trunk is generally short, the material is hard and heavy, the strength is high, the texture is natural and beautiful, the texture is solid and durable, and it is a furniture frame structure.

and the main material used for finishing.

Commonly used are elm, ash, oak, oak, walnut.

Birch, camphor, nanmu, boxwood.

Paulownia, red sandalwood, rosewood, mahogany, colored wood, etc., this kind of wood is more expensive and has a long service life. Among them, the easy-to-process ones are ash, paulownia, mahogany, oak, walnut, colored wood, rosewood, and red sandalwood that are not easy to process, and the flowers and basswoods that are easy to crack are wood, and the hard colored wood, camphor wood, red sandalwood, and elm.

2.Cork. The cork is taken from conifers.

That is, evergreen, the trunk is straight and tall, the texture is smooth, the material is uniform, the wood is soft and easy to process, so it is also called soft wood. The surface density and expansion and contraction deformation are small, and the corrosion resistance is strong. Because of its soft texture, cork generally cannot be used as a material for frame structures in furniture, but is often used as an auxiliary material for non-structural parts, or used to process into various boards and man-made boards.

Cork generally does not deform or crack.

Commonly used cork are: Korean pine, white pine, fir, spruce, eucalyptus, masson pine, cypress, tabuliformis, larch, ginkgo, teak, red sandalwood, etc. Among them, the ones that are easy to process are fir, red pine, ginkgo, eucalyptus, and white pine.

Cork has different weathering resistance, and many tree species also have brown, hard knots, which should be cleaned of the viscous liquid before making furniture, and shellac is carried out.

Sealed treatment. The loose knots should be glued with white glue before shellac treatment.

Cork (phellem), commonly known as water pine, cork, cork, is the outer skin product of a very developed tree species, and the stems and roots are thickened and grow as surface protective tissues.

The main tree species that produce cork are cork oak and cork oak. Plants that are 20 years old or more and have a DBH greater than 20 cm can be harvested for the first time, and the resulting skin is called cephalic bark or primary bark. After that, every 10 or 20 years, the resulting skin is called regenerated skin, and the thickness of the skin is more than 2 cm.

This kind of substance is resistant to decay and chemical attack, so in addition to the corrosion of concentrated nitric acid, concentrated sulfuric acid, chlorine, iodine, etc., it has no chemical effect on water, grease, gasoline, organic acids, salts, esters, etc. It is widely used, such as bottle stoppers, insulation layers for refrigeration equipment, lifebuoys, sound insulation panels, etc.

Cork is harvested from the first protective layer of oak trees, the scientific name is cork oak, because of its light and soft texture, so it is commonly known as cork. Because of its soft texture, it is mostly used as a cork for high-end red wine, as well as building decoration materials such as cork flooring and cork wall panels.

Cork, commonly known as cork, cork. The cork layer of the plant is very well developed on the surface of the outer skin products of the tree species, stems and roots after thickened growth.

In contrast to hardwood, it generally refers to wood that floats in water.

Softwood, i.e. pointer wood, is wood produced from trees of the phylum Pine and Cypress, including pine, spruce, cedar, fir, larch, Douglas fir, hemlock, cypress, California redwood and yew. As the name suggests, because its texture is relatively soft with hardwood, it is also known as softwood, to distinguish it from hardwood, but not all hardwood is harder than softwood, such as yew is a longleaf pine, but harder than most hardwoods, and balsa wood, which belongs to hardwood, is very light and soft.

Softwoods and hardwoods can be distinguished by their small structures, the most important being that cork lacks ducts to transport water, and is usually simple and consistent in structure, consisting of only two types of cells: tracheids and parenchyma. Cork is commonly used in structural components of buildings, but also in furniture and factory woodworking products such as casting molds, doors, windows, etc. Cork is also the main raw material for paper production and the manufacture of MDF.

On the market, wood is classified according to different requirements, and there are countless ways to classify it. According to the characteristics of processing, wood can be divided into hardwood and soft species. Hardwoods and softwoods mainly change their texture and texture due to the differences in each tree species, the environment in which they grow, the soil, and the geographical climate.

For example, hardwood, generally broad-leaved trees, such as elm, walnut, oak, etc., usually this kind of tree species has a short straight trunk, but the tree material is hard, ** is also more expensive, more suitable for making furniture.

Cork, such as conifers, is mostly tall, straight, clear-grained, and easy to process, making it the main material for making wooden cottages. It is made of softer hardwood, which does not allow it to serve as the main frame for furniture. However, compared with hardwood, it has a higher density, is not easy to expand and shrink, and is more resistant to corrosion.

In particular, SPF in North America, the origin of wooden houses, is the top material among the wooden house construction materials.
