CA cylinder stability-2 is designed to determine the stability of the indicator fluid. CA cylinder stability-2 is a cup with a handle, which at mid-height of a challenge to the cork. He designed to determine the stability of the mud. Stability index is defined as the drilling mud density difference between the upper and lower half of the sample solution, otstoennoy during the day in cylinder 200 mm high. The instrument used in the oil fields. It is a cylinder with a drainage tube midway. If it pour the wash solution containing a certain amount of coarse-grained faction and withstand a certain time – then over time there is subsidence of the solid phase and an increase in specific gravity of solution at the bottom of the cylinder. Merging separate solution from the top and bottom of the CA-2 and defining the ratio of their specific gravity – we can estimate the ability of remote wash solution prior to drilling, and if necessary increase to the desired level by introducing an additional quantity of bentonite or reagents enhance the ability to bypass the solution. Design and operation: cylinder stability CA-2 is a cup with a handle, which at mid-height of a challenge to the cork. Determination of stability is carried out by measuring the difference in density between the upper and lower parts of the sample solution. To do this, the side opening of the cylinder cap must be closed, and the stability of the cylinder set on a flat surface. Fill the CA-2 solution to the top and leave it over night. After holding the upper part of his solution poured through the hole. Further measured the density of the upper and lower part of the solution took place. Stability index is defined as difference between the upper and lower halves of the sample solution stand for a day. Storage and transportation: long-term storage of all the metal parts of the cylinder must be thoroughly cleaned and subjected to conservation rustproof lubricant K-17, GOST 10377-78. Transportation of the cylinder must be carried by any mode of transport in conditions which exclude the possibility of direct exposure to precipitation and corrosion. Manufacturer's Warranty: The warranty period of the cylinder 2-CA-18 months from the date of commissioning, under the conditions of its storage and use, but not more than 24 months from the date of manufacture. Specifications: Capacity of 700 5 ml. The delivery cylinder stability CA-2 includes: – a cylinder – the instruction manual.

Sandwich – paneli.Klei and materials for their development sendvichey.Tendentsii competition in the manufacture of sandwich panels is growing. Companies moving towards cheaper cost. Economy puts their priorities in the selection of raw materials for sandwich panels. Interesting changes await us in the market of external walling, the sandwich panels is based on mineral wool, expanded polystyrene and polyurethane foam. The market value of mineral wool slabs are about 1.5 times higher than that of the foam. In this Minplita sold about twice as expensive as its cost. Not far off the fall in prices for Minplita, and then Minplita cost and foam on the market will be equal. Price foam will not fall, because the profit on its production and so is minimal. Non-combustible mineral wool to press very soon, much foam on the market sandwich panels. Polyurethane sandwich panels are currently the best in terms of teplosberezheniya and mechanical characteristics. The problem is their low fire resistance. However, replacing polyurethane foam is a foam tsianauratnaya, which practically does not burn. By the year 2010 will come into effect restrictions on the use of combustible materials in construction, and to press strongly tsianauratnaya foam polyurethane. Existing lines producing polyurethane sandwich will have to change the site of injection and mixing ingredients. New pre-equipped with modern lines of the respective device, working as a polyurethane foam, and the tsianauratnoy such equipment company "Yongming". In the production of sandwiches made of PVC as an "internal" list is almost universally used a cheaper high-impact PS (polystyrene) or ABS. Polystyrene, by the way, stronger than PVC and 0.7 mm thickness for PS is sufficient in case of production to sandwiches window slopes. Excellent high-impact PS is produced by LLC "PolimerMarket", and the most reliable polyurethane adhesive for him – TOP-UR-E-PVC. PVC sheet has long been widely used with a thickness of 0.9 mm, or even 0.8 mm, 1.0 mm and not as it was originally. The best adhesive for sandwich panels remain polyurethane. There is an active search for other cheaper for a base polymer adhesive. But while nothing can come close to polyurethane adhesives for weather resistance and hardiness. One-component polyurethane adhesives costs have long been caught up with two part. A matter of choice of glue – it is a question of equipment used for the production of sandwiches. On continuous lines applies only component polyurethane adhesive. On shotgun assembly lines are applied one-component polyurethane adhesives cure at different rates. Two component adhesive less technologically in the case of bench lines, although some companies have traditionally apply it to this day. Polyurethane adhesive consumption is reduced to 100-120 grams per square meter sandwich panels. More economical use of polyurethane adhesives with low density. Distinguish between low-density glue easily even visually: the glue is transparent, although it may be the color from colorless to red-brown, such as adhesives mark TOP-UR-E-PVC – colorless, and mark TOP-UR-40 yellow-brown adhesive minimum density of 1.1-1.15 g / ml and therefore most economical for consumption. Polyurethane adhesives are high-density: 1.4-1.5 g / ml, is filled with so-called polyurethane adhesives. K-filled polyurethane adhesives include adhesives, most brands and Macroplast Isolemfi. They are opaque, and their color beige or cream. The color is caused by kaolin or chalk, which they introduced to reduce the cost. Filled with polyurethane glues is very heavy, and its relative cheapness, they do not justify – adhesive consumption is quite large, at a cost manufacturer sandwiches even more expensive.
