ã€China Aluminum Industry Network】Aluminum Products Solder Production Technology Currently, aluminum and aluminum alloy products have entered a large number of production and living areas. Once aluminum products are damaged, it is difficult to repair them. Therefore, the production of aluminum, aluminum alloy products into the market, is very popular. Now its production technology is introduced as follows:
First, raw material ratio (parts by weight) Zinc oxide 10, barium sulfate 10, tin chloride 10, tin 40, zinc 20, aluminum 10, potassium aluminum sulfate (alum) a small amount.
Second, production technology
1. Melt. Aluminum, tin, and zinc in the formula were added to an iron crucible and heated to 400° C., melted to form a crucible, and stirred for 20 minutes.
2. Compound. Tin chloride was added to the above molten alloy liquid and stirred for 10 minutes. Additional zinc oxide was added and stirred for 10 minutes. After fully melting, barium sulfate and potassium aluminum sulfate were sequentially added, stirred until completely fused, and stirred for another 20 minutes. Cool down to 350°C.
3. Molding. Prepare a semicircular mold (making pig iron). After the mold is uniformly brushed with talcum powder, the above-mentioned 350° C. composite solution is poured into a mold and cooled for 50 to 60 minutes. Flux zinc oxide, tin chloride, can be replaced with higher quality titanium dioxide (titanium dioxide). The price of this formula is slightly expensive, but the hardness, strength, and finish are higher after welding, especially the quality of welded aluminum alloy doors and windows is better. If only the general aluminum product is welded, the barium sulfate hardener can be replaced by talcum powder in order to reduce the cost.
Third, the use of welding first with a proper amount of 1% dilute hydrochloric acid to wash the damaged place, and then washed with water and dried. 200 to 400 watts of soldering iron can be used for soldering or repair. Aluminum products can also be heated slightly on gas furnaces or liquefied gas furnaces, and the solder blocks can be placed where they are damaged to melt them. After cooling it can be.
Phlizon`s COB series Grow Light emits all the wavelengths of light which can be fully absorbed by the plants to create.
Best full Specturm designed to perfectly match large areas of indooor plants, especially for Medical Plant.
COB + Dual-chip,most efficient spectrum,high PPFD.Two cooling fans with double ball(import from Japan) and big aluminum heat sink to protect the grow lights from high temperature,good cooling,long lifespan.Photosynthesis and promote healthy growth budding and flowering.
1000w/2000w /3000w COB LED Grow Light, it will give you more options when your plants need different strength of illumination.
Grow Lights are a great choice for growers who are dealing with hot HPS lights and want to change to something that's going to run cooler. Although LED Grow Lights do produce heat,the smaller models might not bring up the temperature of your grow space.Even the more powerful models of LED grow lights that produce a lot of heat still have built-in cooling systems to help prevent the heat from beaming directly down onto your plants.

WHAT MAKE UP AN EXCELLENT LED GROW LIGHT ?
1.PPFD Value : PPFD is Photosynthetic Photon Flux Density. When you choose a plant light, you should compare the PPFD values of different plant lights. The larger the value, the better the growth of the plant.
2.Actual Power: Because the actual power of the plant light always varies with different conditions, all Amazon sellers use the rated power to describe the power of the product because the rated power is constant. When you pick a LED grow light, the rated power of the plant light is a reference, and more importantly is the actual power.
3.Core Coverage: In addition to the above two, when you choose a plant light, you also need to compare the cover area of different plant lights, of course, the size of the core coverage area. In general, in germination stage, you can hang the plant light higher and the cover area is larger. In flowering stage you can hang the plant light lower and the cover area is smaller because the plant needs more light at this stage. You have to compare different coverage areas to choose the plant light that suits you.

Suggestions:
1.Clean the dust inside every 6 months to ensure the good heat dissipation and long life time.
2.Don`t keep too short distance to the plant canopy to avert leaves bleaching.
3. Highly hang the lamp will weaken the energy and affect the growth cycle of the plants, so the lamp should not be hang too high.
4. While taking care of the plants, please spray the leaves and branches 2-3 times everyday, to ensure the plants do not wrinkle a wither, and have no phenomenon of few fruit, and hard pericarp
