The problem of pollution in the mainland has become increasingly serious, and it has once again triggered the urgency of promoting energy conservation and environmental protection. The LED industry has entered the take-off period in the lighting industry in the next year. According to the LEDinside report of the research and development organization, the global LED lighting penetration rate is rapidly increasing. It is estimated that the output value of LED lighting will reach 17.8 billion US dollars in 2014 (2014), and the total number of LED lighting products shipped will reach 1.32 billion, which is 68. In terms of regions, the growth rate of LED lighting products in China will reach 86.
LEDinside said that the global LED lighting product replacement tide is caused by the rapid decline in prices, among which the alternative light source products are the most obvious. Bulb lamps and lamps are the most popular alternative light source types, accounting for the 2013 LED lighting products. 38 and 25.
In the mainland market, the government actively promotes the development of the LED industry through subsidy policies, while at the same time dissolving overcapacity and corporate closure caused by excessive subsidies in upstream equipment. LEDinside estimates that the growth rate of LED lighting products in the mainland will reach 86.
The LED lighting market is gradually expanding, and the LED component industry in Taiwan is making efforts to move forward. According to the statistics of the Photovoltaic Association (PIDA), as of 2012, Taiwan’s downstream LED packaging and module industry applications are dominated by display backlights, and revenues account for 33, followed by lighting 20, but it is expected that in the case of various manufacturers actively develop LED lighting market, 2013 will break through 20, shortening the revenue gap between backlighting applications.
Philips, the lighting manufacturer, estimates that LED lighting output will reach 11 billion US dollars next year. The legal person said that LED lighting demand is expected to grow by 50 to 100 this year, and new technologies will further reduce costs, which will help leading players to open up and compete with competitors. The gap, therefore, will be the big one Evergrande, including Crystal Power, Ronda, Everlight and other profitability will improve.
Furniture edge sealing glue can be divided into three categories according to the different base materials:
EVA (ethylene-vinyl acetate copolymer resin) base material hot melt adhesive, this hot melt adhesive can be divided into two types with filler and without filler. Using EVA as the base material is the most common production technology for furniture edge sealing adhesives, and its main limitation is poor heat resistance. The ambient temperature of panel furniture sealed with EVA hot melt adhesive shall not be higher than 120°C;
POL YAMIDE (polyamide) based hot melt adhesive, this hot melt adhesive has good heat resistance and fast curing characteristics, the main disadvantage is that it is expensive.
HMPU (polyurethane) base material hot melt adhesive, it is a kind of hot melt adhesive with the best performance, and it is the guarantee of high quality sheet edge sealing. It is expensive and requires special usage.
The performance of furniture edge sealant
1. Viscosity of furniture edge sealant
The viscosity of furniture edge sealing glue does not directly reflect the performance of the glue. In general, the higher the viscosity of the furniture edge sealant, the better its initial tack strength, but the worse the coating performance. Low-viscosity hot melt adhesives have a smaller amount of glue and better wetting properties. Some hot melt adhesives with low viscosity and fast curing speed may also have high initial tack strength.
2. Density of furniture edge sealing glue
The density of furniture edge sealant is generally 0.95-1.6g/cm3, and its density depends on the amount of filler.
3. Softening point and use temperature of furniture edge sealing glue
The softening point is an indicator of the heat resistance of the furniture edge sealant. The higher the softening point, the less likely the furniture edge sealant will melt. At the same time, softening point is also an important aspect to measure the temperature resistance of panel furniture.
4. The opening time of the furniture edge banding glue and the feeding speed of the edge banding machine
Furniture edge sealant is widely used in the market because of its solvent-free, water-resistant, and environmental-friendly features.
