(1) according to the use environment
Glulam can be divided into indoor laminated materials and outdoor laminated materials. The indoor laminated material is used in an indoor dry state, and the user's requirements can be met as long as the durability in the indoor use environment is satisfied. The outdoor laminated timber is used outdoors, and is often subjected to rain, snow, and sunlight, so it is required to have high durability.
(2) according to the shape of the product
Glulam can be divided into plate-shaped glulam, straight glulam and curved glulam. It is also possible to form the laminated material into a profiled section, such as an I-shaped cross-section laminated material and a box-section laminated material or a hollow section laminated material.
(3) According to the bearing situation
Glulam can be divided into structural glulam and non-structural glulam. The structural glulam is a load bearing member which requires the glulam to have sufficient strength and rigidity. The non-structural composite material is a non-load bearing member, which requires the appearance of the laminated material to be beautiful.
(4) by use
Glulam can be divided into: 1 non-structural glulam; 2 structural glulam; 3 veneer non-structural glulam; 4 veneer structure
Glulam for laminated materials.
Glulam does not change the structure and characteristics of wood. It is still a natural substrate like wood, but in terms of physical and mechanical properties, it is superior to solid wood in terms of tensile strength and compressive strength, and uniformity in material quality. It is also superior to solid wood. Therefore, the laminated timber can be used in place of solid wood in various corresponding fields.
Non-structural laminated material
Non-structural laminated timber is mainly used as furniture and interior decoration materials.
In terms of furniture, the laminated timber is applied to the furniture manufacturing industry in the form of integrated sheets, integrated squares and integrated curved materials.
The integrated sheet is applied to the panel of the table, the side panel of the cabinet, the large-surface parts such as the top and bottom plates, the non-exposed parts such as the cabinet partition, the bottom plate and the drawer bottom plate, and the drawer panel, the side panel, the bottom plate, the cabinet door, etc. Small format parts.
The integrated square material is applied to a table or chair type bracket, a cabinet type tripod, etc., or a circular cross-section component.
The integrated curved material is applied to curved parts such as chair brackets, armrests, backrests, sofas, and coffee tables.
In the interior decoration application, the laminated timber is used as the material for interior decoration in the form of integrated sheets and integrated squares.
Integrated panels are used for stair siding, treads, floors and wall trim panels.
The integrated square material is used for interior doors, windows, cabinet beams, columns, decorative columns, stair railings and decorative strips.
Structural bonding material
Glulam is developed with the increasing demand for long structural members in the construction industry. It is mainly used for wooden structural beams of stadiums, concert halls, factories, warehouses, etc. Among them, three-hinge arch beams are most commonly used. This was not possible in the previous wood structure.
Copper smelting methods can be divided into two categories: pyrometallurgy and hydrometallurgy. More than 85% of the world's refined copper output is recovered from pyrophyllite concentrates and recycled copper by pyrometallurgical process, and the refined copper produced by hydrometallurgy only accounts for about 15%.
In China, copper metal is extracted from copper concentrates mainly by the pyrometallurgical method. The more advanced one is flash smelting, whose output accounts for over 30% of the total copper produced in the country. Due to low energy consumption, large-scale, can effectively control the advantages of environmental pollution. This smelting technology is being developed in the copper industry. Flash smelting furnace according to different working principle can be divided into two types: Outokumpu flash melting, InCo flash melting. The following describes Outokumpu smelting process.
