The kitchen can be a confusing place for most novices. Things like how to chop vegetables or how to properly heat food can intimidate those who are not familiar with kitchen regulations. However, there is one such element that belongs to the kitchen that even most connoisseurs are not familiar with, and that is, which side of aluminium foil is the ‘correct side’. Aluminium foil is widely used as a tool in the kitchen, but little do we wonder why one side is dull, and the other shiny.

We found a large box of Reynolds aluminum foil from 1972. We've been using it for years now, but today I wondered about the wisdom of it. Any reason we should not be using it?

The different heating methods of the UV aging tester need to be mastered urgently!
The ultraviolet aging test uses a fluorescent ultraviolet lamp as the light source. By simulating the ultraviolet radiation and condensation in the natural sunlight, the accelerated weather resistance test is performed on the material to obtain the weather resistance result of the material; it can simulate the ultraviolet, rain, high temperature, and high temperature in the natural climate. Environmental conditions such as high humidity, condensation, darkness, etc., are combined into a cycle by reproducing these conditions, and let it automatically execute the number of cycles.
The UV aging tester is manufactured in accordance with the current GB/T UV aging test standards. It is suitable for plastics, rubber, coatings, inks, paints, resins, printing and packaging, adhesives, automobile and motorcycle industries, cosmetics, medicine, metals, and electronics. , Electroplating, aerospace and other fields.
There are two heating methods generally used by UV aging testing machines, namely, air heating and water vapor heating. These two methods have their own advantages and disadvantages. When choosing, we mainly look at the characteristics of the test product. Let’s talk about the two heating methods. Make a difference:
The two heating methods of the UV aging tester are to increase the temperature in the cavity. Generally, the aging temperature is about 65°C, which can be reached by both water and air. If the temperature is above 80°C, then the water must not reach the temperature. When it comes, there is no such temperature requirement for light aging, so here is the standard aging test. As far as the temperature rise rate of the UV aging test machine is concerned, air heating is relatively faster than water heating, because after we have heated water, steam will be generated to transfer the heat to the air, and air heating is the hot air carrying heat in the UV Forced circulation in the aging testing machine, rapid heat transfer.
When many products are undergoing UV aging test, humidity has a great influence on the surface of the product, especially some products such as coatings. This is stipulated in the national standard. For standard testing machines, it is emphasized that The aging test is carried out in rain, condensation and high humidity environment, and high humidity is achievable for non-standard ultraviolet aging testing machine, that is, steam heating method, along with humidity, relative to wind heating method, There is one more steam heating function, which can simultaneously achieve high-temperature and high-humidity UV aging tests. Of course, if the aging of the product is mainly affected by light and temperature, then both methods are possible.

Application of vacuum technology
VACUUM FURNACE
Metallurgical industry: The vacuum technology used in the metallurgical industry includes molten steel vacuum processing, vacuum melting, vacuum induction melting, induction shell melting, vacuum arc remelting, etc. Among them, the vacuum treatment of molten steel is a very important aspect of the metallurgical industry. This technology is mainly used in the atomic energy industry, aerospace technology, ocean drilling technology, gas engine technology, automobile industry, aircraft manufacturing, high-speed trains and other high-tech industries to control and process certain elements in steel, and to The life and reliability of materials put forward higher and higher requirements.
1600℃ Vacuum Furnace
Electronics and microelectronics industry: Microelectronics technology requires smaller and smaller electronic components and circuits, and higher integration requirements. This is inseparable from the application of vacuum technology, especially the microfabrication technology of VLSI. The formation of geometrical structure, ultra-thin layer growth technology, and particle beam injection technology all require a high-quality and clean vacuum environment, which shows its development Dependence on vacuum technology and equipment.

| Which Is More Expensive? Aluminum Plate Or Stainless Steel Plate? |

Industrial development era, is the revolution of the machine, but no matter what can not be done without stainless steel and aluminum plate.Both are widely used in aerospace, shipping, and other industries.Not classics somebody compares, since the range that USES is same and extensive, so which is more expensive of these two board?
One of the first things you’ll want to take into account is cost. Though you’d be wrong to make a choice based on cost alone, it’s always an important consideration – any project will have a budget and you won’t want to overspend if you don’t have to. The reality here is that aluminum is almost always cheaper than stainless steel. That’s because it’s a bountiful material, it has a lower melting point (so less energy is required) and it’s easier to shape – especially when it comes to rolling it out into thin sheets. That also makes it easier for you to work with, and you won’t need any specialist tools.
Compare aluminum plate and stainless steel plate which is more expensive, in fact, it is very easy to directly see the performance, the performance of a good natural price.From aluminium plate, aluminium material is a kind of environmental protection, do not fade, the metal with high price, besides industrial path also often is used to decorate go up, environmental protection sex is better than general copper makes things that defend bath even, do not have oxidation sex to still be better than stainless steel.At the same time, aluminum plate also has the characteristics of corrosion resistance.
ALUMINUM VS STEEL COST
Cost and price are always an essential factor to consider when making any product. The price of steel and aluminum is continually fluctuating based on global supply and demand, fuel costs and the price and availability of iron and bauxite ore; however steel is generally cheaper (per pound) than aluminum (see galvanized vs stainless for more info on steel). The cost of raw materials has a direct impact on the price of the finished spinning. There are exceptions, but two identical spinnings (one in aluminum and one in steel) the aluminum part will almost always cost more because of the increase in the raw material price.

UV fluorescence ultraviolet aging test box
UV fluorescent ultraviolet aging test box is a device that uses American brand UV lamps to simulate outdoor sunlight, rain and dew and other harsh environments to do rapid aging test for industrial products, so it can also be called ultraviolet UV tester or ultraviolet rapid aging box.
UV fluorescence ultraviolet aging test box is suitable for the aging test of non-metallic materials' sunlight resistance and artificial light source; including 2 types: UV-A wavelength is 315nm～380nm, UV-B wavelength is 280nm～315nm.
Although these UV light, which is much shorter than the natural wavelength, can accelerate the test to the greatest extent, so as to provide a basis for the improvement of material formulations and product performance. After the test, through testing, it is judged whether the performance of the product can still meet the predetermined requirements, so that it can be used for product design, improvement, identification and factory inspection. The reason for using the U.S. imported UV lamps of the Asia-Pacific brand is because they are more stable than other domestic lamps and can better reproduce the test results.
