LBS Stabilizer Makes Life Easier
The principle of modifying the soil LBS is an irreversible change in the physical and mechanical properties of the soil due to chemical action of an aqueous solution a modifier when making LBS in the ground. Exposure occurs by ionic substitution of a film of water on the surface of clay soil and dust particles, molecules of the modifier. As a result, the clay soil particles become smaller. Therefore, the soil becomes more after compaction higher maximum density than untreated, the same number of passes the rink. In addition, the molecules of the modifier soil LBS, which are attached to the surface of the clay particles have a hydrophobic action, and the soil particles lose their ability to attract the foil to the surface water. Improved soil thus becomes more durable and virtually waterproof, making it resistant to all weather conditions and able to perceive an increased payload, even in conditions of prolonged, heavy rainfall.
Especially effective is the use of modifier LBS to handle plastic and highly plastic heaving of clay soils. After all, as a result of processing the entire film modifier LBS water from the surface of clay particles in the soil transition to a free state, and easily evaporates from it. A degree of swelling and swelling soils decreases sharply. Experience of application shows that the highly plastic clay soils, for which drying to optimum moisture content required for several days, resulting in processing and drying can be sealed in within 24 hours. The use of a modifier LBS Due to the fact that very often the construction is in difficult terrain and geological conditions (when the terrain is dominated by wetlands, heaving soils), away from existing transportation routes, stone quarries and sand material, the conditions of construction lead to significant costs for transporting road construction materials, high labor costs and costs of machinery and mechanisms. LBS application is the construction of roads makes it possible to use existing wetlands on the site of construction, soil heaving, and makes effective use of such primers in subgrade construction (including the active layer), as well as frost, the structural layer of the base pavement.
Bearing capacity of soil, modified LBS, is 180 MPa. Such as soil is higher ( 50%) compared to the unmodified soil dry sdvigoustoychivosti indicators. Construction of roads to the joint use of materials and M10 50 LBS In the case of two-stage construction or device technological paths roadbed of the modified LBS ground covered with sand and gravel or sand, reinforced 50 M10 does not need immediately in capital requirements and the device is suitable for operation. Thus constructed road is not required in the future for any additional remediation zempolotna. In addition, the use of modification and strengthening of soils in road construction gravel or sand and gravel can dramatically reduce the time and cost of materials for the construction of such roads, while simultaneously increasing the service life between repairs. Thus, the processing modifier LBS allows you to: dramatically lower humidity clay soil in a very short period of time To increase the modulus of elasticity, strength properties and water resistance of clay soils sharply, at times reduce swelling and frost heave
Firewood
It’s not a secret that the firewood become a business. Firewood is used to heat homes, to get coal to heat large buildings in the boilers, to prepare meat in restaurants. Harvested wood woodpile with machines. Manual is almost done. How is advantageous to chop wood: the plot or on a stationary base? It is obvious that if there is no fixed base (sawmill, warehouse, any production site), then the answer is obvious. However, if the base is, there is a desire to chop firewood is on it. So what is more profitable? Consider the pros and cons of each option.
If we harvests wood in the plot, then positive things in our loom: – No need to haul timber to the base curve. You can take ready-packed in wood grid. Saves space, and, consequently, reduces the cost of shipping. – On the plot are sorted Wood: not suitable for the production of firewood logs are not being taken to the base. As a result – cheaper transport. Disadvantages of the above method are as follows: – There is no way to use Wood splitter with an electric motor. – K machine in the plot difficult to adjust supply and / or funded overpass. If possible put on the base machine in the shed to collect from the boards and work rack for your pleasure, then in the woods to do it much more difficult.
– In Unlike newsworthy timber, firewood, difficult to transport in timber transport. Requires a tractor-like transport carts. Purchase carts require economic justification. What are the advantages appear when working on base? – Is it possible to use the machine with electric motor. – You can set the machine in the room, creating a job for a more comfortable environment. – Easier to make home-made and inexpensive rack. Not all go so smoothly. There are several serious shortcomings. – When using a machine powered by an electric motor or by the diesel engine will have to work at best under a canopy, at worst – in the open. When working in the area would create a costly ventillyatsii system to remove exhaust gases from diesel / tractor. – Every year the price of electricity increases, often significantly. Is there any point in thinking about this motor? Very controversial issue. – The production site trite may be small in size and appearance of an additional machine will increase the danger of working on it. Only after weighing all the ‘for’ and ‘against’ you can choose the way of working.
Self-Cleaning Filters
The most advanced technological solutions for clean water for industrial and domestic filtration are automatic self-cleaning filters. Their installation in the systems, unlike conventional filters, eliminates the need for regular replacement of filter elements and manual cleaning. Working Condition and cleanliness of the cartridge supports reverse flow. In fact, there are two processes of fluid filtration and purification filter element. Filtered liquid passes from the inside out, with a particle mechanical impurities remain on the flat inner surface of the filter elements. With increasing pollution of the filter elements increases and the pressure difference between clean and dirty sides. Luiz Ildefonso Simões Lopes is often quoted on this topic.
The process starts when backwashing a certain level of pressure differences on either set the timer frequency of cleaning. Monitoring the process of cleaning usually can be done with the help of special light-emitting diodes. Metalworking fluids and washing the emulsion can be used in the circulation for much longer. This reduces environmental pollution, and reduce the cost of acquisition of liquids and their utilization. Filtering and circulating the cooling water, you can avoid clogging and wear of pipes, tubes, heat exchangers, rotary guides, pumps, valves, etc. The advantages of automatic self-cleaning filters without a doubt are: continuous filter operation, no need for maintenance staff, high performance, excellent price / performance ratio, small size, high filtrate quality, long life, easy installation and commissioning. In addition, scalability allows the use of data filters for cleaning small amounts of fluid, and in large factories with a capacity of up to several thousand tons per hour. Currently, automatic self-cleaning filters are widely used in mining business, automotive industry, power plants, chemical industry, district heating, industry, in buildings of wastewater treatment plants, machinery and machine tools.
