Deputies of the National People's Congress proposed to moderately control the restrictions of high-rise buildings to blindly compare diesel generators | diesel generator prices / 2012-03-12
“The maintenance costs of water supply and power supply for high-rise buildings are three times higher than those of general buildings, and the chances of escape are beyond the limit of fire protection. The higher the building, the greater the number of casualties caused by earthquakes. Weighing the pros and cons, the economic significance of high-rise buildings is affected. It is questioned that countries all over the world are increasingly cautious about high-rise buildings.†For this reason, Shen Lirong’s representative suggested that it should strictly perform the procedures for the demonstration and approval of high-rise buildings, appropriately control landmark high-rise buildings, and conduct safety inspections on existing high-rise buildings. .
With the development of China's social economy and the accelerating process of urbanization, the contradiction between population size and limited land resources has become increasingly prominent. In order to resolve this contradiction, high-rise buildings in the city have rapidly emerged, and there is a tendency to increase the coverage, increase coverage, and increase the number of blindly comparisons such as “domestic heights†and “higher world levelsâ€. Shen Lirong told reporters that high-rise buildings have played an important role in saving urban land, shortening the development cycle of public facilities and municipal pipe networks, and accelerating the improvement of people's living conditions. However, there are still many dangers.
Shen Lirong suggested that according to the overall urban development plan, comprehensive consideration should be given to factors such as the impact of massive population concentration on urban supply and transportation, and coordination among single high-rise buildings and high-rise buildings with the surrounding environment, existing buildings, places of historic interest and scenic beauty, and urban outlook. Distribution relationship. She also suggested setting the height of high-rise buildings according to the existing firefighting capacity, thoroughly checking the existing or existing high-rises, and checking the safety hazards such as construction and power.

Rutile Titanium Dioxide
Rutile Titanium Dioxide is used in coatings, plastics, paper, printing inks, chemical fiber, rubber, cosmetics and other industries. It has a high melting point and is also used to make refractory glass, glaze, enamel, clay, high temperature resistant laboratory utensils, etc.
At the same time, titanium dioxide has a good UV shielding effect, and is often incorporated into textile fibers as a sunscreen. Ultra-fine titanium dioxide powder is also added to sunscreen cream to make sunscreen cosmetics.
Titanium dioxide is not only used as a coloring agent in the rubber industry, but also has the functions of strengthening, anti-aging and filling. Titanium dioxide is added to white and colored rubber products. It is resistant to sunlight under sunlight, does not crack, does not change color, has high elongation and is acid and alkali resistant. Titanium dioxide for rubber is mainly used in car tires, rubber shoes, rubber flooring, gloves, sports equipment, etc., generally anatase type. However, when used in the production of automobile tires, a certain amount of rutile products are often added to enhance the anti-ozone and anti-ultraviolet capabilities.

Titanium dioxide is also widely used in cosmetics. Because titanium dioxide is non-toxic and far superior to lead white, almost all kinds of fragrant powder use titanium dioxide instead of lead white and zinc white. You only need to add 5%-8% of titanium dioxide to the fragrance powder to get a permanent white color, making the fragrance smoother, having adhesion, absorption and hiding power. In gouache and cold cream, titanium dioxide can weaken the greasy and transparent feeling. Titanium dioxide can also be used in various other spices, sunscreens, soap flakes, white soap and toothpaste.
The glaze made of titanium dioxide has strong transparency, low quality, strong impact resistance, good mechanical properties, bright colors, and is not easy to be polluted. Titanium dioxide for food and medicine is titanium dioxide with high purity, low heavy metal content and strong hiding power.
