With the progress of society, many home renovations now use insulation materials. These insulation materials are mainly determined by the thermal conductivity of the material (its index is the thermal conductivity). The harder the heat transfer of the material (ie, the smaller the thermal conductivity), the better the thermal insulation performance. In general, the common characteristics of heat insulation materials are light, loose, porous or fibrous, and the conduction of air is blocked by the non-flowing air inside. Then, the next small series for everyone to introduce what is the insulation material and insulation material which. What is thermal insulation material Insulation material is a new type of material composed of waterproof insulation material solution and heat reflecting and heat insulation material. The material sets reflection, radiation and hollow microsphere heat insulation and integrated, and can be used for solar infrared light in the range of 400nm-2500nm. Ultraviolet reflection can effectively prevent the sun from accumulating heat on the surface of the object, and it can automatically radiate heat and cool down. Insulation material can transmit external heat to the interior of the object even when the atmospheric temperature is high, and the three functions ensure that the object coated with the paint cools down, ensuring that the internal space of the object can maintain a constant temperature state. It is understood that the existing insulation material products on the market can reach a temperature lower than 20°C when the sunlight is strong, and the temperature can be reduced to more than 3°C on cloudy days and nights, or to the same temperature as the atmospheric temperature. In addition, the heat insulation material also has the effect of waterproofing, especially for small cracks with good waterproof and anti-seepage effects; in addition, the heat insulation material is also rich in color, thin layer, decoration, self-cleaning, waterproof, moisture-proof , UV aging, acid and alkali, anti-corrosion and other effects. What are the insulation materials 1, barrier insulation materials Barrier thermal insulation material is a material that achieves thermal insulation through low thermal conductivity and high thermal resistance. These materials were developed at the end of the 1980s and have different product names, such as composite magnesium aluminum heat insulation materials, rare earth insulation materials, and coating type composite silicate insulation materials. It is an insulating coating made of inorganic and/or organic binders, insulating aggregates (such as sepiolite, vermiculite, perlite, etc.) and air entraining agents. 2, reflective insulation material Reflective and heat-insulating materials are based on aluminum-based reflective and heat-insulating materials. By selecting suitable raw materials and formulas, high-reflectivity coatings are produced, and sunlight is reflected to achieve thermal insulation. Thin layer heat insulation reflective coatings are representative of this type of material. It consists of the base material, heat reflective pigments and additives. This kind of thin layer thermal insulation reflective coating has high thermal reflectivity, generally more than 80%, and the heat insulation effect is obvious. However, as described above, the color has a great influence on the thermal reflectance. 3, radiation insulation material Radiating and heat insulation materials emit solar energy absorbed by buildings in the form of long waves into the air through radiation, so as to achieve the effect of heat insulation and temperature reduction. As an exterior paint, high emissivity is required. The emissivity of organic materials is generally in the range of 0.80 to 0.90. The key to exterior wall thermal insulation coatings is to prepare coatings with high thermal emissivity.

Roof waterproof insulation coating waterproof kitchen waterproof decorative paint coating LED is the abbreviation of Light-Emitting Diode. It is made of semiconductor materials. It has a positive pole and a negative pole. When DC is applied to its positive and negative poles, it will emit light. From 1907 to 1993, LED has experienced 86 years of history. The application of LED technology is generally divided into visual and non-visual categories. The application of visual category includes LED lighting technology, and the non-visual category includes plant photosynthesis and medical care.

LED process:
The whole production process of LED Lamp Beads is divided into epitaxial chip production, chip production, and lamp bead packaging. The whole process reflects the manufacturing technology level of modern electronic industry. The manufacturing of LED is a combination of multiple technologies and a product with high technology content. The knowledge of LED for lighting purposes also needs to know how LED lamp beads are produced.
LED epitaxial wafer production process:
LED epitaxial wafer growth technology mainly uses organic metal chemical phase deposition (MOCVD) to produce synthetic materials with semiconductor characteristics, which is the raw material for manufacturing LED chips
