The main challenge for road passenger transport comes from the safety of passenger transport, and the increasingly severe passenger transport security situation will lead the state's competent authorities to issue more stringent regulatory measures. In the short term, these regulatory measures may have some impact on bus companies or bus operators. However, in the long run, the construction of a regulatory system can further ensure the safety of passenger transport and help passenger transport companies expand market space. ——Deputy Secretary General of the China Road Society Bus Division At present, the Chinese road passenger transport industry under the influence of the “three highs†of high-speed rail, high oil prices, and high costs faces various challenges. Zhen Zhenqing believes that there are currently three factors that benefit the passenger transportation market: First, the 12th Five-Year Plan of the Ministry of Transport portrayed a clear blueprint for road passenger transport. First, the road passenger transport network will continue to improve. According to the plan, by the end of 2015, the total length of highways in China will reach 4.5 million kilometers, which will increase at an average annual rate of 100,000 kilometers. Zhen Zhenqing believes that "this is the basis for the continuous expansion of the total plate in the road passenger transport industry." Secondly, during the “12th Five-Year Plan†period, the country will build more than 100 comprehensive passenger hubs connected to railway passenger transport, of which 36 key cities will build about 40 sets of roads, railways, rail transit, city buses, taxis, and so on. The form of a modern, large-scale integrated passenger transportation hub. The construction of such passenger transport hubs has enabled the seamless integration of road passenger transport, urban public transport and railway transport, increased passenger flow, and further expanded the passenger car market space. Thirdly, the "12th Five-Year Plan" put forward the "encouraging the development of large and medium-sized high-class passenger cars" to realize the standardization and specialization of transport equipment, so that the market share of mid-to-high-end passenger cars by the 12th Five-Year Plan period will be 28% by 2010. It is a huge opportunity to rise to 40%. Second, the continued growth of road passenger transport will continue. According to the data released by the Ministry of Communications, during the “11th Five-Year Plan†period, the average annual growth rate of China’s road passenger traffic is 8.14%, and the annual growth rate of passenger turnover is 10.02%. In 2010, the total number of passenger transportation in China was 32.8 billion, which represented a year-on-year increase. 10.2%. Among them, 1.68 billion passengers of railway passengers were up 9.9% year-on-year, 30.63 billion passengers were on highways, up 10.2% year-on-year; water transport declined, and civil aviation increased slightly. Highway passenger transport accounts for 93.3% of the total passenger traffic in the country, and railway passenger transportation accounts for 5.12%. Zhen Zhenqing said that as long as the country’s economic development continues, road passenger transport will maintain its momentum of sustained growth. Thirdly, affected by the high-speed rail accident, the EMU is decelerating at a large scale and the railway passenger transportation is cooling down. This is a development opportunity for bus companies and passenger transport companies. “In the past ten years, the speed of railway passenger transportation has increased seven times in a row, and the impact on road passenger transport is quite far-reaching. The railway transportation has a direct impact on highway short-distance passenger transportation in the one-hour, two-hour, and three-hour travel intervals.†Zhen Zhenqing said: “Take Beijing to Tianjin as an example, after the intercity high-speed rail from Beijing to Tianjin was opened, the passenger trains on this line were basically diverted. However, the current situation has undergone a new change. The high-speed rail accident has caused the railway transportation to cool down, and the highway passenger transport Hope to look up." Furniture edge sealing glue can be divided into three categories according to the different base materials:
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.

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.
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.
