ã€China Aluminum Industry Network】 1. Chemical Polishing and Electrochemical Polishing Under normal operating conditions, aluminum materials tend to flatten the brightness of aluminum surfaces due to the cutting action of chemical liquids. After a certain period of time, the brightness of the aluminum surface no longer increases. There is only an equilibrium reaction of aluminum in a chemical solution. Exceeding this limit time, quality problems such as pitting, air flow, etc. may occur on the surface of the aluminum material.
2. The effect of hydrogen fluoride ammonia mist at a concentration of 160--180G/L. Ammonia fluoride reacts with the aluminum matrix and is automatically inhibited for about 40--60 seconds. If the haze effect is increased, the aluminum material must be acidic or alkaline. Activated 3, alkaline etching process in the production of hydrogen fluoride after some plants have alkaline etching process. Some factories directly use alkali plus sodium nitrate or sodium nitrite for alkaline etching. The sand surface will reach its limit under certain operating conditions. Sand surface effect will not increase.
4 Anodizing The general mechanism of oxygen pores is familiar at home. It should be noted that the oxide film is continuously dissolved by sulfuric acid during the formation process, and only the film formation rate is higher than the acid dissolution rate to generate the oxide film. There is a limit to this. At a certain current density, the dissolution and formation of the oxide film at a certain temperature is a dynamic equilibrium process. The film thickness will not increase any more. Different materials, different process limit film thickness is not the same.
5, the emergence of rainbow oxide film is due to the oxide film is too shallow.
6. When dyeing is done in dark colors, it will not be dyed deeply. That is, the oxide film absorbs dye molecules to reach a saturated and strong state, such as black, deep red, and the like. Sometimes some of the light colors will stagnate with the increase of the dyeing time when the dye concentration is low. Therefore, the dark color of the sample can be made to control the thickness of the oxide film to produce a limiting effect.
7. There are different materials on the same workpiece. Different aluminum materials will have a great influence on the surface treatment effect. For this phenomenon, the initial brightness of different aluminum materials can be approximated and then the subsequent process can be performed. This can reduce the difference in surface treatment effects due to material differences. 8. These phenomena have a reference role in the development of the sample, the determination of the process, and the design of the production line.
Products Description
LED Grow Light is the newest trend for indoor growers. Advanced LED Grow Lights use less energy,and create less heat,not only provides intense, effective lighting for indoor gardening but also make the garden cool. Hydroponics,which is a method in high-tech horticulture where plants grow in soil-free nutrient baths,led hydroponic lamp is a perfect example of how science and technology can work together to develop solutions to human problems.
Advantages for led grow light
1. Bring You High Yield
The traditional grow lights, such as HID and HPS can just bring you 0.5 -0.8 gram per watt, no more than 1 gram. But the led grow light can bring you 1-2.5 gram per watt. It's amazing! LEDs in greenhouses deliver same yield as grow lights, using just 25% of the energy. So as for the energy conservation and environmental protection light source, the planters will consider the led grow light as their first choice.
2. Less Heat
While most grow lights are very warm, as HID, so you would need use the fan to solve this problem in summer. LED grow lights are generally moderate in temperature, and they will not harm a person if he touches them. As such, it is much safer and convenient for owners and their crops, they can be placed very close to the plants to deliver high intensity lights to the surface of the leaves.
3. Low Cost On Everything
Less electricity, save about 60% than HID.
Low amounts of heat, means less money spent on the room's costs of cooling.
Long life-span, no need to replace the bulbs.
No ballast.
No reflector.
