In the second half of the year, the new products will be the main source of growth kinetic energy with high-density products. The legal person is optimistic about the accumulation of the third quarter in the third quarter of the World Football Expo, the operation grows compared with the second quarter, and the fourth In the season, the ultra-dense screen will also be expected to have a low season performance.
Accumulation shows that with the increasingly fierce competition in the LED market, the company can improve its operations in addition to active cost-down, increase the proportion of high-end new products, and provide customer follow-up services (SLA).
MAPP is colorless in both liquid and gas form. The gas has a pronounced acetylene-like or fishy odor at concentrations above 100 ppm, due to the addition of substituted amines as a polymerization inhibitor. Low molecular weight alkynes have strong odors. Mapp Gas is toxic if inhaled at high concentrations. Mapp gas is a mixture of various hydrocarbons, principally, methylacetylene , propadiene and Propane(MAPP). It produces a relatively hot flame (2,976Â°C) with a high heat release in the primary lame (inner cone) (15,445kJ/m 3 ), less than for acetylene (18,890kJm 3 ) but much higher than for propane (10,433kJm 3 ). The secondary flame (outer cone) also gives off a high heat release, similar to propane and natural gas. The combination of a lower flame temperature, more distributed heat source and larger gas flows compared with acetylene results in a substantially slower pierce time.
