FAQ

Can foil be insulated?Indeed, the foil is reflective of the sun's rays

The use of aluminum foil is very extensive, such as aviation food packaging, cigarette packaging and other packaging ordinary carnivorous. The experts divided it into more than 20 varieties according to its application characteristics. Because of the difference of economic development in different countries, there is a big gap in the consumption structure of aluminum foil. In Europe and the United States, aluminum foil used in packaging accounts for 70% of the total demand. In the Chinese market, aluminum foil is mainly used as raw and auxiliary materials for industrial manufacture. Packaging aluminum foil accounts for only 30% of the total domestic demand. Although the development of aluminum foil packaging is late, the market is growing rapidly and the prospect is interesting.

The foil or foil can be isolated (or reduced) computer radiation:

2, pay attention to the use of the screen brightness and distance: to adjust the brightness of the screen when using the computer, the bigger the screen brightness, electromagnetic radiation is stronger, the smaller the contrary; but it can not be stressed too dark, so easy to cause eye fatigue. Keep at least 50 cm to 75 cm distance, which can reduce the damage of electromagnetic radiation. If there is a condition, you can install a special color filter board on the display screen to reduce the harm of radiation. At the same time, make sure that the screen is clean.

What are the application areas of aluminum foil?

Four major aluminum foil applicationsI. composite foil for automobilesWith the rapid development of automobile and aluminum rate of China's automobile industry continues to improve, the rapid increase in foil market demand for automotive vehicles, there are two kinds of foil, a composite foil is used for automobile air conditioner, automobile air conditioner China has aluminum, aluminum foil on the annual demand of 15 thousand tons; the other a composite foil for auto radiator, used in the manufacture of automobile radiator, condenser and evaporator, the auto radiator aluminum rate reached 40%, the annual demand of 3 thousand tons.

The action of perforating aluminium foil and non perforating aluminium foil

Heat passes from a higher temperature to a lower temperature

The foil can be used in the microwave heating?

Microwave produced by microwave oven belongs to radio frequency band, usually around 2500MHz. This band of microwaves has the following features: 1) it can be absorbed by food and water, causing molecules to move violently and produce heat. 2) not absorbed by plastics, ceramics, or glass. 3) the metal conducts electricity under the influence of the electric field of the microwave

Aluminum foil (aluminum foil) heat transfer of heat insulation is how, orThe old radiator looked black and looked uncomfortableA friend suggested wrapped with aluminum foil, has good heat dissipationOn the radiator, aluminum foil feel hot, not hot outHope to get your bachelor's scientific explanationThe foil blocking heat radiationThat is to say, tinfoil radiators (in the case of no gap) will affect the heat, huh

Heat conduction is important, but for heating or air conditioning, the area of heat dissipation is more important, that is, the contact area between air and heat sink

What are the areas in which aluminum foil is applied?

International and domestic production and application of inorganic polymer flocculant have scale, theoretical research has also been further developed. The main raw materials are bauxite, aluminium hydroxide, waste molecular sieve catalyst and so on. The main preparation methods are wet method, electrolysis method and so on. Some scholars believe that the aluminum foil has the advantages of high recovery and reuse of economic value. He experimentally studied the optimum conditions for the preparation of polyaluminium chloride by using waste aluminum foil and the applicable range of the purified water

Can foil foil be put on and off?

Most of the foil is shiny on one side and the other dull. Aluminum foil for food can be wrapped on both sides, and it is generally recommended to enhance the heat transfer effect with bright bread wrap. Aluminum foil paper is soft and easy to change, like paper, and it doesn't bounce after deformation
