Thermobonded

If the "filling" bed springless design – a single layer of foam, then the purchase of a couch, in my opinion, not worth it. Your back will certainly resound pain syndromes, orthopedic requiring elementary comfort, and serve it a little. Soft "puff" for a sweet sleep Standart budget sofas, more often, is a combination of the spring unit and foam. Modern technologies have improved the technical characteristics of foam that served as the active use of it in custom-made furniture. Foam rubber is often referred to Polyurethane (PUR), artificial latex, puralateksom, vaterformom, anti-allergenic latex eliochelom, elastofomom, vaterlateksom, bilaksilastom. Such a variety of names – a publicity stunt with a claim to unique use of soft layer. His performance is good enough: the material is elastic, creates a comfortable base for a dream, do not cause allergic reactions. The best option of filling is a combination of different materials filling, allowing more brightly to express certain qualities of bed.

Lateksirovannaya Coir – the material of the nut coconut fiber, impregnated with the composition of natural rubber latex. Increases the elasticity of the sofa. Sleeper with the filling – a great prevention of scoliosis and degenerative disc disease. May be an ideal option for filling the children's sofa. In addition, the material creates a heat exchange and air circulation, gipoallrgenen, which makes possible its use of asthmatics.

High strength characteristics of the sofa bed provides layers of latex, a natural material from the juice Hevea. It is soft, quickly recovers its original shape, characterized by high wear resistance. At David Zaslav you will find additional information. As a rule, is filling expensive sofas. Environmentally friendly material perioteka (based on polyester fibers) successfully used as a filler economy class. Gives softness and elasticity of the couch, provides an excellent air circulation, retains heat well and does not cake. Experts believe higher quality perioteka material than foam. However, it is inferior in durability of polyurethane foam. Another common material for filling the couch is sintepon (synthetic batting, sintepuh). Volume, lightweight, and relatively resilient enough cheap material, which gives low-cost furniture made to order effective relief. Holofayber often used as a filler, holds its shape better syntepon. It has high durability. High-elastic synthetic fabric dyurafil quickly takes its original form even after prolonged stress. Sofas stuffed with dyurafila not absorb moisture, do not cause allergies, are resistant to combustion, which explains their popularity in furniture industry. Feather and down fillings are expensive models. These natural materials will give a volumetric couch and become comfortable resting place. The modern technological solution – sofas from "memory effect". Increased strength and softness of the upper layer of material memoriks allow the sofa to take shape when heated to exactly match the contours of the body and keep it for a while. By virtue of its special properties, memoriks is not a popular filler. "Memory effect" typical of materials with memory eterlon hyperviscosity, memoriform, bilaksilast hyperviscosity, memorial vaterform and others. In fact, it is memoriksa species. To the sofa was a long time … To ensure good preservation of soft layer and the best individual properties are used in the construction of ancillary materials. Thus, the layer Thermobonded felt, consisting of natural and synthetic fibers, will protect key components from wear. Spandbond performs a protective function and promotes uniform distribution of load on the springs. Vent cushioning material will create a good air circulation. Flooring jacket harboring box spring, sofa will give greater softness.

. Mass fraction of humus in accordance with GOST 26213-84, as a percentage, the lower boundary of topsoil should be: in the forest steppe and steppe zones – at least 2, in the southern taiga forest, arid, semi-desert, foothills of the desert-steppe, subtropical foothill semidesert and desert, subtropical shrub-steppe and suholesnoy, subtropical, vlazhnolesnoy, in the northern forest-steppe zone of gray forest soils, soils in mountainous areas – at least 1 in desert and subtropical desert – not less than 0.7. Mass fraction of humus in a potentially fertile soil layer, the percentage should be in the forest steppe and steppe zones – 1-2, in the dry steppe and desert zones – 0,5-1. 2.1.2. The pH of the aqueous extract of fertile soil layer should be 5,5-8,2; in podzolic soils zheltozemnyh, red earths and soils of mountain regions – not less than 4.0.

Measuring the pH of the aqueous extract is carried out according to GOST 17.5.4.01-84. The pH of the salt extract of sod-podzolic Soil should be at least 4, 5, in a peat layer – 3.0 – 8.2. Mass fraction of exchangeable sodium, percent, from the cation exchange capacity, shall be: in the mixture formed a fertile layer of black soil, dark chestnut, chestnut soils and gray soils, saline soils in the complexes – no more than 5 on feebly and srednesolontsevatyh varieties of zone and hydromorphic soils steppe and steppe zones – to 15, on a weekly and humus-poor southern species srednesolontsevatyh chernozem, brown, chestnut soil and gray soils, and hydromorphic soils semihydromorphic arid and semi-arid zones – up to 10. Determining cation exchange capacity is carried out according to GOST 17.4.4.01-84. Water-soluble toxic salts in the fertile soil layer should not exceed 0.25% by weight of the soil, limit the allowable number of water-soluble toxic salts in the fertile soil layer can be increased to 0.5% when used in irrigated sites. Measurement and calculation of the amount of toxic salts produced according to GOST 17.5.4.02-84.

Mass fraction of soil particles less than 0.1 mm should be in the range – 10 to 75% on the floodplain, oxbow, deltaic sands and sandy sediments priarychnyh – 5.10%. Large-scale soil maps should be used to establish the model, podtipovoy, genera and species belonging soils. Optionally set the standard removal of topsoil with the structure of the soil cover on the soil of northern, northwestern, north-eastern provinces, territories and autonomous republics, with tundra, permafrost taiga soils, as well as in the taiga-forest zone of podzolic soils in large parts And the Central Asian republics of Kazakhstan, located in the desert, foothill desert-steppe, subtropical desert zones. Do not set the standard removal of topsoil in the case of a discrepancy it GOST 17.5.3.05 and soils to a great extent gravelly, strongly and very, very stony, weakly, moderately and heavily washed sod-podzolic, brown forest, gray and light gray forest, moderately and severely eroded dark gray forest, dark chestnut, sod-calcareous, yellow soils, red earths, gray soils.
