Metal : Aluminum is a common metal used in daily life. It's found in kitchen utensils, cans, foils, and even in the construction of airplanes and buildings due to its light weight and resistance to corrosion.
1.Common materials in daily life
Laser holographic materials are a new type of material widely used in packaging and anti-counterfeiting printing. The raw materials used for laser holographic films mainly include PVC, PET, OPP, BOPP, etc. The varieties include laser aluminum coating, laser transparent polishing film, laser hot stamping paper, laser transfer paper, etc. The colors include gold, silver, red, blue, green, black, etc. Laser holographic materials integrate laser holographic image anti-counterfeiting technology with printing and decoration technologies such as hot stamping and molding, which have good anti-counterfeiting effects. This not only improves the decoration effect of the product, but also adds anti-counterfeiting performance. In addition, laser holography technology is combined with other technologies to produce products such as laser holography with fluorescent anti-counterfeiting film, flexible transparent laser holography anti-counterfeiting film, and atomic nucleus confidential anti-counterfeiting laser holography film, which further improves the quality and anti-counterfeiting effect of laser holography film.
2.Two new materials
Analysis of advantages and disadvantages of polyethylene insulation：
1. Advantages
(1) Lightweight: Polyethylene insulation board has a low density and weight, which can reduce building loads.
(2) Insulation: Polyethylene insulation board has good insulation performance and can reduce energy consumption.
(3) Waterproof and moisture-proof: Polyethylene insulation board has excellent waterproof and moisture-proof properties, which can reduce leakage.
(4) Easy to construct: The construction of polyethylene insulation board is simple and fast, which can shorten the construction period.
2. Disadvantages
(1) Easy to age: Polyethylene insulation boards are prone to aging over time, resulting in a decrease in insulation effectiveness.
(2) Flammable: Polyethylene insulation board is flammable, and safety precautions should be taken during construction.

When woodworking wood, due to the large amount of wood dust, N95 grade masks are sufficient
After inhaling wood dust, it is prone to respiratory and pulmonary inflammation. And it's very painful, so be sure to take good respiratory protection measures.
To prevent lung injury, in addition to dust reduction and sealing in the work environment, individuals need to scientifically choose dust masks.

Dust masks, as special labor protection equipment, must be certified by GB2626-2006.
1. Therefore, when choosing a mask, it is also necessary to choose according to the national standard. In the national standard, for dust and oily particles, protective masks are divided into oil proof (oil smoke, oil mist, dust, smoke, mist, microorganisms, represented by KP) and dust proof (dust, smoke, mist, microorganisms). For dust prevention, there are three levels of protection: KN100, KN95, and KN90. The protection rates for ultrafine dust are ≥ 99.97%,>95%, and>90%, respectively.
2. Masks are divided into disposable, replaceable filter type half masks, and full face masks. For long-term occupational protection use, especially in environments with high dust concentration, heavy smoke and other ultra-fine particles, it is recommended to use a replaceable filter cotton type half face mask. Disposable masks are mostly of no size and are relatively low-grade.
3. Mask materials include silicone, plastic, etc. Silicone materials are relatively soft and comfortable, with low facial pressure.
4. The size of the mask is divided according to the national standard, which is particularly important. Many masks are not numbered, and the effect will vary from person to person.
5. There are two types of masks: covering the mouth, nose, and jaw. The second type has a large contact mask, good sealing, and low pressure.
6. Do not ignore respiratory protection. Using fake and inferior masks, gauze, towels, etc. as masks can easily lead to the occurrence of lung diseases. At present, some common N100 level dust masks can ensure protection while breat
Steel parts undergo oxidation treatment to form a protective oxide film on the surface, mainly composed of magnetic iron oxide (Fe3O4). The color of the film is generally black or blue black, while cast steel and silicon steel are brown or black brown.
The oxidation treatment methods include alkaline oxidation, alkali free oxidation, and acidic oxidation. Commonly used for the protection and decoration of machinery, precision instruments, instruments, weapons, and daily necessities.

Plastic : Polyethylene（PE） is the most common type of plastic. It's used in a variety of products, from plastic bags to water bottles, toys, and even bulletproof vests. It's known for its durability and flexibility.
1. To polish wood, the first step is to prepare an electric film, a grinding machine, and a design drawing. Pop ink lines on the wood, first construct a simple shape, and then use a polishing machine.
2. Use a trowel to preliminarily polish to form a rough model, and then use different grinding wheels, such as 120 and 320, to polish in order of thickness. Next, use sandpaper to directly remove the scratches on the surface, and then choose a larger grinding wheel for further polishing. The rules are the same as before.
3. After polishing, the next step is to polish. To achieve coloring and polishing, sandpaper of different thicknesses should be used for polishing. It is necessary to choose the right pigment, which is generally water-soluble and has strong permeability. Mix with water in a certain proportion and apply it to the wood. After coloring the wood, do not immediately dry it. After drying thoroughly, use a clean cloth to repeatedly wipe until a uniform gloss is achieved and feels smooth to the touch.
Wood sponge is made by treating with chemicals, peeling off hemicellulose and lignin, and can absorb oil from water. The absorption amount is 16-46 times its own weight, and it can be reused up to 10 times.This new type of sponge surpasses all other sponges or absorbers we use today in terms of capacity, quality, and reusability.Future development trend: Oil and chemical spills have caused unprecedented damage to water bodies around the world. As a green way to clean up the ocean, wooden sponges can effectively solve this problem.
