    A container for containment of bituminous products formed by inner (10) and outer (11) flexible casings in intimate contact. The inner casing (10) is of a material which has a softening temperature which is above that of the bituminous product (B) when loaded into the container but below that of the bituminous product (B) when it is applied in use, usually by spraying. This inner casing (10) is of a material which has a viscosity at the application temperature which enables the material when melted with the bituminous product to be applied therewith. The outer casing (11) is made from a material which has strength characteristics which enable it to contain the inner casing (10) and bituminous product (B) during the filling of the container as well as during transportation and storage thereof. The outer casing (11) is impervious to movement therethrough of the contained bituminous product, components or additives thereof and preferably has a softening temperature such that melting does not occur at the application temperature.

    专利说明:

    The invention relates to packaging means or containers for bituminous products.
    The bitumen mass is transported by sea in tankers, and by land in large steel road and rail tankers made with insulation designed for heat retention or equipped with a tubular heater and gear pump. Smaller quantities of bitumen products are transported in 150- or 200-liter steel containers that are drum-shaped or other, and they are burst or heated at one end to remove the bitumen. Thus, the cost of packing and transporting bitumen is very significant especially when the container cannot be reused after emptying it from the bitumen or when the container is to be returned empty for re-filling.
    Cardboard containers are known in which, to prevent bitumen from sticking to the walls, the inner surface is coated with a material to which the bitumen does not stick. It is also known an inner coating of a material that adheres to the bitumen, but does not adhere to the outer cardboard coating. In this case, the insulating material is homogeneous with bitumen and melted in bitumen when the latter is prepared for use. .
    Low-melting polyethylene is characterized by high tensile strength and therefore the packaging does not have sufficient strength to store bitumen in it.
    In addition to the problem of temperature strength, the packaging is not strong enough to be able to be folded into several Rus during storage and transportation.
    To fill the container with bitumen, the bitumen must be raised to its pour point. During the filling of the package with bitumen, the temperature of the film also rises, which leads to a significant decrease in its strength. Immediately after filling, the package cannot be moved until its temperature drops and the strength increases so as not to be damaged.
    Such known packages are used for refractory bitumens. For road grades of bitumen, the problem of its discharge is important.
    A known container for the transport of bitumen, comprising a casing made of a sleeve, preferably polyethylene l,
    Closest to the proposed technical essence and the achieved result is a package for bitumen, containing two tubular shells placed one inside the other, and the inner shell is made of high-pressure polyethylene with a softening temperature of 60-120 ° C and viscosity that melts it together with bitumen 2.
    However, these packages are unreliable in use.
    The purpose of the invention is to improve the reliability of the operation of the package.
    This goal is achieved by the fact that in a package for bitumen containing two tubular shells placed one inside the other, the inner shell is made of high pressure polyethylene with a softening temperature of 60-120 seconds and a viscosity that melts it with bitumen, the outer shell is made of polyamide film.
    The thickness of the polyamide and polyethylene films may be respectively. 02-0.07 and 0.02-0.1 mm.
    On one of the shells or between them can be placed grease based on polyethylene.
    The outer casing prevents leakage of components of bitumen and other petroleum products, which may be contained as additives in bitumen, such as, for example, kerosene, diesel fuel and mineral turpentine.
    Bituminous products are actually bitumen, asphalt, tar, pitch, bituminous and asphalt mastics; however, the proposed package is most applicable for bitumen grades used in road construction.
    FIG. 1 shows a package filled with a bitumen mass, a longitudinal section; in fig. 2 - the same, cross section; in fig. 3 - the same, option.
    The inner 1 and outer 2 flexible shells are seamless tubes, with the inner sheath 1 made of low specific gravity polyethylene (0.910-0.9251 or another similar co-size film, while the outer sheath material is a refractory polyamide film, the so-called polyacroamide (nylon 6). The thickness of the polyethylene is 2070 microns (0.02-0.07 MMj, and the thickness of the polyamide film is 20-100 microns (0.02-0.1 mm).
    In the proposed package, polymeric or copolymer materials with a softening temperature of 60-120 s can be used. The temperature at which road bitumen is sprayed is lOO-lSO C. In this range, the material softens to a viscosity at which it can be used in conjunction with bitumen products. The material is suitable for use with bitumen products, since it has the same specific weight and thermal stability at the temperature of use of bitumen, does not alter any significant elasticity or adhesive ability of bitumen, and also does not decompose. When mixed with bitumen, polyethylene does not form poisonous, corrosive or explosive substances, and also does not emit volatile and harmful vapors.
    The inner shell material does not have sufficient strength to hold the bitumen when filling the container or to ensure safe transportation, while the outer shell of approximately the same diameter is strong enough to preserve the inner shell and bitumen. Nylon 6 has a tensile strength, which is especially high at the filling temperature of the shell with bitumen. Since the melting point of nylon is 195-220s, it does not melt at the spray temperature at which bitumen is used. As a consequence, it can easily be removed from the machine or filter, which is the standard equipment of the sprinkler.
    Bitumen can be mixed with diesel fuel, kerosene, turpentine, or other petroleum products (spitting, mixing, mixing, or adding). Such additives or components of bitumen do not penetrate the squaw outer nylon sheath. Nylon does not corrode and resists hydrolysis and microbiological effects. When water is exposed to bitumen (other than emulsifying bitumen) | when bitumen is heated to be used, boiling of water occurs when the boiling point is reached, as well as increased foaming of bitumen. Such foaming bitumen can spill out of the reservoir, which is dangerous for personnel, increases the fire hazard, leads to loss of product and causes contamination. Nylon outer sheath is water resistant, which minimizes the above problems.
    The inner and outer shells 1 and 2 form a pipe with double walls of the required size, closed on one side, and the bitumen mass 6 enters the inner shell. The outer shell 2 over its entire surface is in direct contact with the inner
    shell 1 in such a way that the inner shell has a support in the form of an outer shell when filled with bitumen. However, it is necessary that the outer shell be placed in a rigid form during filling of the container. Immediately after filling, the tubular casing is closed, and then it can be sent to a warehouse, where the filled tubular casing is piled up or placed in shipping containers of various sizes. Since the temperature of fusion of the inner shell is higher than the bitumen loading temperature, no undesirable effects occur. Although the tensile strength of the inner shell decreases due to the increase in temperature to such a limit that it is not in itself capable. retaining bitumen is not a problem, since the tensile strength of the outer shell is sufficient to prevent the inner shell from breaking.
    Packed bitumen products can then be sent to the consumer either in separate packages or placed in containers. The package does not need to be insulated or heated for transport. The package weight is 25-50 kg for easy loading. In addition, the ends 3 of shells 1 and 2 behind the seal have a length of about 100 mm so that the shells can be conveniently lifted.
    The ends of the tubular sheath can be sealed as follows.
    The shell is pre-assembled and then tied with a waterproof cord or clamped with a clamp 4. In another embodiment, the end may be placed in a heat sealer, and due to the different properties of nylon and polyethylene, only the inner circumference of polyethylene is sealed. In order to seal the outer shell, its end is attached and clamped (see the left side of the container in FIG. 1).

    In order to release the bitumen mass, the outer shell is pulled off, and the inner shell containing the bitumen mass is placed in a preheater (which can be a sprayer at the same time) and heated to the temperature of use of the product (100180 ° C), and the inner shell is melted . The resulting product can be applied to the surface to be treated by spraying or mixed with other products during the production process. Due to the properties of the inner shell material and its small amount, not exceeding 0.2% of the weight of the bituminous mass that is contained,
