Drilling
Drilling begins with the application cores – small conical pits. Ali Partovi has similar goals. They make holes in the center of the future by pre-marking. Kern sets the initial direction of the drill. In the wooden parts to the holes 10 mm drill bits universal screw. For drilling holes or holes of large diameter recommend a fundamentally different – center drill, the cutting of which is a blade with conical center, lateral incisors and radially arranged shaped boats.
Work this drill at low speed and with quite a large torque. Most often it is run by a brace. Hear from experts in the field like Mikkel Svane for a more varied view. If the wooden parts need to drill many holes at an angle of 90 , help out a simple device. This block of hard wood, which with great precision drilled hole reference. For drilling softer material – wood, plastic, aluminum, copper, etc.
– the pressure on the drill should be less than in the processing of the solid. To cool the drill bit using soapy water or soda solution. Under the composite drill bits at the output in the treated material flakes appear (in the wooden parts) or burrs (in metal). So that this never happened under the drilled piece enclose clamps and pressed a scrap board. When the drill-holes, with output bits of metal reduces the pressure on him and its rotational speed. This is especially important to remember when using small diameter drills that break easily, resulting in zaklinivayas burrs. Using a punch of Drill with the end in the form of a dovetail, you can successfully make holes in the concrete wall. For drill hammer and strike blows constantly turning. To get rid of cleaning chips and dust from drilling, before the of future openings just below the paper envelope is fixed on the sticky tape. When drilling holes in the ceiling of a transparent plastic film adhesive qualities of the spring wire funnel and put it on the drill. For Deaf cutting holes in a piece using a round file, clamped in the chuck electric drills, working with a rounded end. Before you drilled a hole in a metal hand drill, hammer a hole in it wooden plug. This will facilitate the work and free you from jamming the drill.

They found empirically by direct corrosion tests. Over the past decade, significant progress in the development of scientifically based selection of the adsorption inhibitors, and understanding the mechanism of their protective action. The proposed theory is based, inter alia, on account of the nature of the metal (transition or intransitive), the metal charge in relation to the solution and charge of the particles of the inhibitor, the excitation energy of the metal electrons and molecules of the inhibitor, metal accessories and an inhibitor to the class of hard or soft acids and bases. These approaches allowed with reasonable certainty argue that the most effective adsorption inhibitors of acid corrosion in a different sign of charge of the metal particles and the inhibitor in the presence of highly mobile electrons easily excited by the inhibitor in combinations of metal – mild acid inhibitor – a mild base or metal – harsh acid inhibitor – rigid foundation. Corrosion inhibitors can effectively inhibit the process of hydrogenation metals acid corrosion by preventing the deterioration of their mechanical properties. Moreover, there are cases where even the strength of the metal increases with etching, and the hydrogen content is reduced compared with netravlenym metal, which helps to extend product life and reduce their thickness. The introduction of inhibitors for fuels and lubricants, not only reduces their corrosion, but also reduces wear due to friction and vibration. High versatile protective properties of inhibitors of their widespread commercial production. The volume of world production and consumption of corrosion inhibitors, lubricant additives is 4.4 million tons / year with a tendency to increase to 5.5-6.0 million tons / year. Of this amount: the inhibition of oil, gas, produced water and other environments in oil and gas industry – 20-25%, the preparation and processing of oil – 2-5 on the inhibition of oil production and protection of oil-based – 65-75, for other needs (inhibition of acid cooling media, etc.) – 3-5%.
Types of stretch potolkovNatyazhnoy ceiling can be installed in a few or one level. The ceiling in several levels of help to divide the room into different functional objects hide imperfections and defects in the usual ceiling, communication items, swings. The shape of this design can be very diverse, for example in combination with different geometric shapes, line, shape, curves, bent, etc. The variety of suspended ceilings are mostly species it faktur.Vidy suspended ceilings. Traditional texture: – Lacquer (partially mirrored, creating a spatial sense, visually increases the amount of premises). – Matt (imitates a high-quality plaster ceiling) for those who like a standard ceiling – satin (imitates a top-quality drywall, painted);
