At the academic forum held in March this year on the theme of "Resist flame-retardant fiber development direction," experts and scholars, representatives from colleges and enterprises, and enterprise representatives agreed that the flame-retardant fibers in the future will be directed toward "performance improvement and price reduction." The direction of development. China Labor Insurance Network 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.

As flame-retardant fibers, thermal protection fibers are mainly characterized by safety, functionality, and comfort. From a safety point of view, the fiber can be formed into a protection integrated: this fiber is made of natural raw materials, and the flame retardant medium is implanted in the cross section of the entire fiber to make it an integral flame-retardant fiber, which is inherently flame-retardant. And Lenzing FR fiber is an environmentally friendly fiber, this flame-retardant medium will not be removed by washing or rubbing. This feature makes it intrinsically different from some flame-retardant viscose fibers.
Functionally protects wearers from burns: We know that high-risk professionals who are prone to burns need to wear special protective clothing. If a person's skin is burned by 15%, the result can be fatal. Thermal protective fibers protect skin from thermal damage through its synthetic flame retardant media, unlike other high performance flame retardant fibers.
From the comfort point of view, the thermal protection fabrics have good air permeability, hygroscopicity and good affinity to the skin. These are important components of excellent flame-retardant protective clothing. On the one hand, these properties are also LENZING FR fiber poles. Earth reduces the risk of hot cramps and thermal stress. Lansing's protective fiber protects the wearer from burns of 2.3 in an emergency. On the other hand, for special clothing that prevents radiant heat, because the heat-protective fabric is in the form of aluminum, extreme radiant heat can be prevented, and the wearer's comfort can be improved, further preventing thermal cramps and thermal stress. Bad effects.
In fact, each type of flame-retardant fiber has its own advantages and disadvantages, and the main idea for future development of flame-retardant fiber is to complement each other. Under the premise of guaranteeing the normal durability of the fabric, the comfort of the fabric should be improved. This requires us to consider the overall design of the fabric, select different types of fiber materials at different price points to complement each other. At present, most of the domestic flame-retardant fabrics are 2 or 3 types of fiber blends. In the future, 5 or even 6 different types of fibers can be considered for blending. Only by making full use of the different properties of different fibers, can the performance and price be further improved. For reasonable performance fabrics.
At present, most of the enterprises engaged in flame-retardant textiles development in China lack the capacity for independent innovation. Most of their products come from the copy of foreign fabrics, which results in domestic fire-retardant fabrics with low technological content and no international competition. However, due to our country's actual national conditions, our company can not use the high cost of flame-retardant fabrics. For example, many firefighters in the United States currently use PBI fiber-blend fabrics. Their flame-retardant and heat-insulating properties are recognized by everyone. , But the price is expensive, making it impossible for the domestic sector to be widely used. This requires our textile companies to take the initiative to develop, reduce the cost of fabrics, and reduce the burden of production costs as the dominant idea for product development.
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
