Increased Production Standards

Doroshenko VS, Ph.D., FTIMS NASU best technology end of the 20th century, improving, stayut firmly on an industrial basis, provide income and attract investment in new production, determining its competitiveness. Structural changes in the economy during the transition to a market highly competitive removed the need for mass production and raised the demand for small and medium series of castings with increased size and weight accuracy, and also improved performance characteristics. Under these conditions, the development of the domestic foundry industry is on the way stand-alone medium-sized shops with flexible technology castings high accuracy and complexity when the method of casting on gasified models (LGM) was the most suitable place in the casting sand-clay molds, investment casting, permanent mold in, or in other ways. In this method of casting a model casting means already half the cast to get itself out of metal. Model Casting – polystyrene (The everyday name – foam), as the packaging of a TV, or a single plate of food, which are punched out million in vending machines, and polystyrene plates insulated exterior walls of high-rise buildings. On a similar technology for a series of castings made from the powder model of polystyrene in lightweight aluminum molds when heated to 130 degrees. S. For single and large casts (sometimes up to several tons) of suitable cutting patterns of the plates foam. Model and obtained by her cast have high accuracy and a competitive presentation, aided by color model of a fast drying paint with a powder-refractory.

Patching Road Surfacing

Patching of the roadway has several advantages: first patching can be done quickly, and secondly, patching does not require huge financial costs, and third, patching can be done without large amount of specialized equipment. Patching is mobile road-building crews. Patching is one of a kind of maintenance. Patching done in the When it is impossible device surface layer. Typically, asphalt patching in Russia are beginning to perform more often in the spring, although it is exceptional and the need for such repairs. Now we consider patching technology. In the first stage is cut on site repair and coating material is removed, then is laying asphalt mix, all the ends align and seal laid surface.

There are several ways of cutting at patching: – planer by cold or hot milling – pneumatic hammer obrubochnym – floor saws. Planers Planers removed damaged coatings at relatively low cost, have a wide range of applications. Planer can remove all sorts of wear and tear zone coverage, potholes and other defects in blacktop. Immediately after passing traffic is allowed to lay asphalt milling mixture. Floor saws good and relatively inexpensive substitute for road milling floor saws are considered floor saws easy road equipment. Used mainly for road construction and patching.

Floor saws are divided into light (100 kg) and heavy (over 100kg). Heavy floor saws are mainly used for cutting large cement concrete thicknesses (over 150). Light chasers (50 to 100 kg) during the patching of roads. When processing the external borders of the card using a jackhammer is pitting them further operation, which greatly reduces the life of the pavement. When using a jackhammer floor saws used only for the destruction and seizure within the map coverage. Removing the coating In the absence of a milling machine permitted to remove the coating material by hand. Practice shows that many secondary uses asphalt shot. In such cases, the sizes of pieces should not exceed 100h100h100 mm asphalt paving mixtures Fresh concrete overlay mixture is placed into the prepared card. Laying the mixture at patching done by hand. Alignment and seal coating sealing the laid asphalt laid cover with patching performed Plate compactors are in class and light equipment used mainly in areas inaccessible to rollers: around wells, in the narrow aisles, in the immediate proximity to the walls of buildings, patching and sealing the alignment of small card cover (1 to 2 square meters). There are lightweight (100 kg) and heavy (over 100kg) thickeners. . Heavy compactors are generally used for sealing soil, gravel and sand roads podsypku. Lightweight – for sealing small areas of asphalt coatings and for patching. Patching – the most important part of the operation of the road!

Classification Wallpaper

Types of wallpapers: classification and characteristics. What we know about the wallpaper? Yes almost anything if we do not take into account the fact that once you choose for your room wallpaper, we are with them and live for many years, nourished by their energy and raising the general vitality. It's true – when we go to bed or wake up in the morning, our eyes first of all boil down: No, not at her sleeping husband / wife / girlfriend / stranger / stranger, and most that are on our wallpaper. Therefore, they must choose wisely, slowly, so you do not feel all rest of their lives. After all, you never know when you have enough money again to repair? The fact that the wallpaper – it's the most traditional and long-known to all the finishing material. Well, for us this word means? A roll material, usually in Paper-based (but in some cases without), which is attached to wall surfaces with adhesive. With careful deeper into the topic, it appears that most of these wallpapers so many forms: scatter eyes while something will choose suitable, beautiful and comfortable.

Classification Wallpaper vodostoykocti: – free routine. Such ekzemplyarchiki not withstand water, they require only a dry rub (rub some contaminated areas with a cloth or processing of vacuuming, but without contact with the wallpaper brush) – waterproof wallpaper. These, by contrast, kept rubbing the less contaminated areas with a damp sponge or soft cloth without the use of detergents – washable wallpaper – maintain clean water and detergents; – Free high-resistant – vinyl. These are clear and can withstand all of the above even more. By type of surface: – plain wallpaper – wallpaper with a raised pattern, and applied to surface in the production process – from wallpaper squeezed a small figure – with a deep pattern wallpaper – multilayer.

How To Prepare Land Before Construction

Site preparation prior to building. Preparatory work before the built-up area. Do you have a desire plot, a plot of land and funds for construction. Then proceed. First, you need to know what kind of house you want and do or by the designer to draw a house and set the dimensions of every detail in the flesh to the size of the steps on the porch (if you are planning out). Further possible to calculate precisely the cost of building materials and payment the work that you can not or do not want to do. To this value add another 25% it will cost you a rough construction costs. After this first work to be done before proceeding to the base unit, is to prepare the site.

Need to get rid of rubbish stored on your site. Pick up trash in one pile by hand (using a special tool or Off-Highway Applications), or polypropylene bags bring up the machine for garbage collection. After all the garbage is removed from the yard must be pre-drawn house plan to transfer land to remove the topsoil from the land location foundation and move it into the garden. The next step in the approach of your dreams in a beautiful home is in the lining of the site. It should get rid of hills, dips, if any, and other irregularities hinder the implementation of zadumnnogo.

Once done all the preparatory work should take delivery of the material for the construction of foundations, think about storage. You should not take more than you calculates to develop in the near future. Striotelny material tends to deteriorate rapidly. So take care of the storage conditions of that purchase and zavezete on the subject. Solutions must be stored under cover to few inches above the ground. Construction site VedBud
