Comprehensive List of Erosion Control

In urban areas, erosion control techniques are primarily concerned with stromwater runoff management, but soil loss due to winds and sloped properties must be considered as well. Here is a list of the most common erosion control methods: Reforestation – This is the method of restoring or restocking existing woodlands and forests that have been depleted due to lumber harvesting,

Oil Sands Extraction and Processing | Natural

Currently, 20% of oil sands reserves are accessible via mining techniques. Large shovels scoop the oil sand into trucks which then move it to crushers where the large clumps of earth are processed. Once the oil sand is crushed, hot water is added so it can be pumped to the extraction plant. At the extraction plant more hot water is added to this mixture of sand, clay, bitumen, and water in a

DIY Interior Wall Painting Tips & Techniques

Here are some good painting tips: When coverage is difficult to estimate, add more rather than less when doing DIY wall painting. You can always pour the leftover back into cans. For large jobs, use the bucket and a roller screen rather than a roller tray. It's much faster to load your roller with the screen than to use a roller pan. Simply dunk the roller into the paint bucket, then roll it

The Metal Casting Process Explained | General

The crucible process, a technique used for producing fine or tool steel, appeared and disappeared in various locations around the globe since the early 1st millennium CE. The technique popped up in India and central Asia first, until it appeared in northern Europe around 800 CE, where it was used to make Viking swords. The technique didn't resurface until 1750 when Benjamin Huntsman

Tips for Sanding a Wood Deck Before Refinishing

After a deep power washing, the wood fibers of the various components of the deck often raise as they expand with water.Once dry, these wood fibers can often remain raised and may cause splinters. For this reason, you should plan on sanding your wood deck after power washing and before staining and sealing.This crucial step will ensure that your refinishing job gives great results.

New separation technique for waste plastics -

The new separation technique is entirely different from conventional methods based on only differences in density. Plastics with the same density can be separated by this process. The plastic separator can be used for many purposes: for separating plastics from mixtures, elimination of foreign matter such as paper, fibers, aluminium foil, copper wire chips, sand, and glass from plastics

Sand Casting Process, Defects, Design

Using sand as the mold material offers several benefits to the casting process. Sand is very inexpensive and is resistant to high temperatures, allowing many metals to be cast that have high melting temperatures. There are different preparations of the sand for the mold, which characterize the following four unique types of sand molds. Greensand mold - Greensand molds use a mixture of sand

Different Types of Casting Processes used in

Plaster casting is similar to the sand casting process, using a mixture of gypsum, strengthening compound, and water in place of the sand. The plaster pattern is typically coated with an anti-adhesive compound to prevent it from becoming stuck against the mold, and the plaster is capable of filling in any gaps around the mold. Once the plaster material has been used to cast the part, it

Integrating Multiple Production Analysis

Implementation of the proposed workflow will prevent unrealistic (either too low or high) reserve bookings by integrating multiple production analysis techniques. We demonstrate where and how each component technique should be used as well as their limitations. We also demonstrate how each technique can be used to reinforce/validate results from other techniques
