Starting from the actual situation in China, many scholars have proposed the development strategy of ecological building materials.
1. Establish the theory and method of building material life cycle (LCA), and provide scientific basis and method for the development strategy of ecological building materials and the environmental coordination of building materials industry.
2. Produce traditional building materials at the lowest resource and energy consumption and minimum environmental pollution, such as the production of high quality cement materials using new dry process technology.
3. Develop building materials that greatly reduce building energy consumption, such as new composite wall and door and window materials with excellent functions of light weight, high strength, waterproof, heat preservation, heat insulation and sound insulation.
4. Develop building materials with high performance and long life, which greatly reduce the material consumption and service life of construction projects, such as high-performance cement concrete, thermal insulation, decoration and decoration materials.
5. Develop building materials that improve the living environment and health functions of the living room, such as antibacterial, deodorizing, temperature regulating, humidity conditioning, shielding of harmful rays of multifunctional glass, ceramics, paints, etc.
6. Develop building materials that can replace high production energy consumption and toxic to the human body, such as non-slate fiber cement products, non-toxic and harmless cement concrete chemical admixtures.
7. Develop industrial waste recycling technology, use industrial waste to produce building materials with excellent performance, such as building materials produced by using slag, fly ash, silica fume, coal gangue, waste polystyrene foam.
8. Develop new building materials that can control industrial pollution, purify and repair the environment, or expand human living space, such as building materials for the development of special cement such as ocean, underground, saline-alkali land, desert, and marshland.
9. Expand the range of available raw materials and fuels and reduce dependence on important raw materials that are high quality, scarce or depleted.
The blade of a cutter knife is very sharp, and there are several parallel scribe lines on its blade. Because it is usually used to cut wallpaper, it is also called a "wallpaper cutter". Cutter knife is usually used in the decoration and advertising plaque industry. The biggest feature of the cutter knife is that it can be easy to replace the segmented blades. You can fold off the unsharp section of blade when using it, so the sharpness can be maintained without sharpening the blade frequently.
