Using Stamped Concrete Overlay Plano

The application of Stamped Concrete Overlay Plano takes time to be learned and homeowners have to study some basic things to get it right. For those who take time making stamped concrete, they are basically applying a finishing technique to concrete so that it will turn out with the look of anything other than concrete from wood to stone to slate. A transformation of simple concrete is what happens here as the concrete is given a far better and more pleasing appearance. Working with stamped concrete is something that a lot of homebuilders really love doing. Nowadays, project costs can easily be driven up if real stones or shells are used in the process of making a house. Apart from allowing those who build homes to select from a wide range of designs, costs are kept at a minimum when they resort to stamped concrete. It is possible for homeowners to apply stamped concrete themselves saving them more money in the long run. Of course you will need several tools and materials but basic masonry skills will also be required in this case. Improving the look of a DIY overlay is possible and when it comes to this, you can rely on the assistance of a professional. Clean the surface well with acid before you do anything else. Acid effectively cleans concrete and mixes its alkalinity. Remember that the acid has to be washed off with water from a pressurized source and see to it that the water has been combined with ammonia so that the acidity is balanced and a good coat emerges afterwards. After the pores are cleaned well enough, everything should be dried out. Apply a thin coat of concrete and then work on the design you wish to have. You can also use prefab concrete overlays to make your task really easy. This is what homebuilders refer to as decorative concrete. Normally, concrete is used to make buildings and houses but it can also be used in decorating them afterwards and decorative concrete is a construction technique that builders rely on for the very purpose of designing a space. Everything from the patio to the driveway to the kitchen countertop can be jazzed up with this particular process. Common color shifting methods include dyeing or coloring but there is something known as acid staining that relies on a more complex chemical reaction to achieve a certain look and this is another version of decorative concrete apart from stamped concrete. Here is where you can achieve a chemical reaction by mixing the concrete with some water, salt, and muriatic acid as the minerals in the concrete like lime for example interact with the solution. After a few hours, pat yourself on the shoulder for having created an artistic effect of earth tone colors on your driveway or patio. Remember to thoroughly wash your hands after doing this as muriatic acid can easily irritate the skin. Aside from ammonia, you can also use baking soda when you clean your driveway or patio. Whiting can better be controlled when baking soda is used. Another method you might want to try is water-based staining. Acid treatments are not advisable for those with kids and so this becomes the better alternative but the process is the same. Water-based staining creates the same coating effect without changing the physical makeup of the concrete. In Plano or not, this is easy to accomplish by yourself or with the help of experts in the field and whatever option you choose, you will be able to get something that you will be proud of in the long run. Rather than go with Plano, you might like stamped concrete overlay Southlake. Houses can look a whole lot better with the help of stamped concrete overlay Plano.

What mass of Cu(NH3)4Cl2 reagent is required?

In the production of printed circuit boards for the electronics industry, a 0.430 mm layer of copper is laminated onto an insulating plastic board. Next a circuit pattern made of a chemically resistant polymer is printed on the board. The unwanted copper is removed by chemical etching and the protective polymer is finally removed by solvents. One etching reaction is:

Cu(NH3)4Cl2 (aq) + 4NH3 (aq) + Cu(s) -> 2 Cu(NH3)4Cl(aq)

A plant needs to manufacture 7500 printed circuit boards, each 7.85cm x 11.5cm in area. An average of 90.5% of the copper is removed from each board (density of copper=8.96g/cm3.)
What mass of Cu(NH3)4Cl2 reagent is required?

Best Answer...


The volume of copper per circuit board laminate is:
0.0430 cm * 7.85 cm * 11.5 cm = 3.88 cm³
The mass of the copper per circuit board laminate is:
(8.96 g/cm³) (3.88 cm³) = 34.78 g
The mass of the copper removed per circuit board laminate is:
0.905 * 34.78 g = 31.48 g
The mass of copper removed from 7500 circuit board laminates is:
31.48 g * 7500 = 236,077 g
The number of moles of Cu to be removed is:
(236,077 g) / (63.5 g/mol) = 3,718 moles.
The stoichiometric ratio is 1:1 between Cu(NH3)4Cl2 and Cu, so the same number of moles of Cu(NH3)4Cl2 is required. Since the molecular weight of Cu(NH3)4Cl2 is 202.5 g/mole, then:
(3,718 moles) * (202.5 g/mole) = 752,844 g of Cu(NH3)4Cl2 is needed. This corresponds to 753 kg, or about 0.75 metric tons.
