Чай грузинский.
Чай зелёный, являясь гигроскопичным грузом, требуют поддержания в трюмах умеренной температуры (около 15оС) и оптимальной влажности. При повышенной влажности чай плесневеет. Грузовые помещения для чая должны быть сухими и чистыми. Совместно с чаем нельзя перевозить грузы, обладающие запахом или воспринимающие его. Чай нельзя грузить вблизи источников тепла, а также грузов, выделяющих влагу. Чай зеленый перевозится в ящиках, имеет УПО 3,2 м3/т .
6.General description of cargo
1. Marble.
Marble - crystal-grained metamorphic carbonate rock, the product recrystallized limestone, at least - dolomite. Due to the close coupling of calcite grains each breed is well polished. In engineering and construction marble call any carbonate rocks, giving in satisfactorily polished - limestone, dolomite or marble. Metamorphism of pure limestone leads to the formation of marble, since the only possible change of calcite at high pressures and temperatures - its recrystallization. At least partial recrystallization of calcite can occur without the participation of dynamic metamorphism, and in some ancient limestone strata have been turned into marble without affecting diastrophism.
Marble composition during metamorphism does not change. Original carbonate rocks - or limestone or dolomite. Accordingly marble consists of calcite or dolomite or both minerals. However, if the original rock contained as impurities in the form of quartz, silica or kaolin, is formed during metamorphism such characteristic lime silicate, as tremolite, pyroxene and phlogopite. Carbonaceous material, dispersed in the limestone may be converted to graphite (pure carbon).
Some varieties of marble - the fine-grained, coarse-grained others so that they are well visible cleavage rhombohedron of calcite grains on. Marble hardness 2.5 - 4, bulk density 2.63 - 2.92 g/cm3. Conventional lime marble rapidly boil, dissolving in dilute acids, but dolomitic marble boil only in powder form. Pure calcite marble - insulator, has excellent electrical insulating properties.
Marble coloring is light, but the presence of even a fraction of a percent of impurities - silicates, iron oxide and graphite - leads to painting rocks in different colors and shades, including yellow, brown, red, green, and even black, and there are colorful, colorful marbles.
Marble deposit. Marbles spread quite widely. The most popular are Italian marble. The famous white statuary marble is mined near Carrara in Tuscany. Is also famous yellow Parian marble from Greece - a favorite material of Greek sculptors. In the U.S., considerable thicknesses of marble occur in the eastern part of the country - in Appalachia and other areas. Marble mining is also in North Africa. Large deposits of dolomite marbles are in Natal (South Africa).
In Russia, the marble is mined in the Urals and the Far East, in Karelia, Altai, Krasnoyarsk Territory in Ukraine - in the Carpathians, Crimea, Donetsk region, in Georgia, Armenia, Uzbekistan and East Kazakhstan. Fine-grained white marble sculpture Malguzarskogo field in Uzbekistan, according to experts, the best of the famous Carrara.
2.Alabaster
The name "alabaster" is derived from the Greek word alahastros, the exact value of which is not known for certain. Other names of the mineral and its varieties: Roman pearls olbastr, lyubastr, alabaster, alavastr.
Alabaster is a type of plaster. Coloring mineral usually white, but there are shades of pink and green. Glitter - silky. Density - 1.3-2.6 g/sm1. The main deposits of the USA, Germany, England, Italy, France, etc.
3.Cardboard
Kind of paper, material, consisting mainly of vegetable fiber, is different from the paper quality, thicker leaves and weight per square meter (250 g/m2). Distinguish between single-and multi-layer board. By appointment board is divided into: Binding, insulating (for transformers, oil-filling machines, etc.), Industrial and Engineering for various purposes (calibrated, jacquard, upholstery, waterproof, corrugated gasket, container glued flat, insulating gasket, suitcase), construction (face).
Cardboard (baled)
Formed by a stack of sheets of cardboard bookmarks between wooden frames whose sizes correspond to the sizes of cardboard. According to a pile of planks on frames tightening the wire, or more steel band. Bale size can vary over a fairly wide range of: length - 850-1520 mm, width - 600-1000 mm, height - 200-600 mm. Weight - 100 600 kg. RLV-1 ,4-1, 7 m3 / t
Cardboard (in rolls)
The size and weight of packages vary; ordinary rolls: height - 700 - 2100 mm, diameter 600-1300 mm, weight - 300-2000 kg widescreen height 2200-2650 mm, diameter - 1100-1500 mm, weight - 2500-3000 kg export Roll: height - 950-2650 mm diameter - 1100-1450 mm, weight - 1200-3000 kg.
RLV - 1.5-2.1 m3 / t
4.Georgian tea.
Green tea, as a hygroscopic cargo holds are required to maintain a moderate temperature (about 15 ° C) and optimum moisture content. When wet moldy tea. Cargo spaces for tea should be clean and dry. Together with the tea can not carry loads that have a smell or perceive it. Tea can not be shipped away from heat sources, as well as goods that produce moisture. Green tea is transported in boxes, has UPR 3.2 m3 / t.
