Abstract

A process for covering waste or compost heaps with a plastic film, comprises applying plastic to the surface in liquid form, which then hardens to form a film.

Description

The present invention relates to a method for Ab Covering waste or compost heaps with an art fabric film.

It is often desirable to have compost, waste or the like to cover unpleasant odors tie. In the same way, there is often a desire Objects or surfaces from dirt, weather to protect rivers etc. In the first place, these will be Targets achieved with the appropriate objects, areas are laid.

For example, the waste to be treated is known or compost in a pile and through one Cover tarpaulin, then with sandbags, old tires and the like is weighed down. The unventilated rents are then rotated several times during the pre- and post-rotting set to ensure an adequate supply of oxygen Afford. As an alternative to this, DE 92 14 354 U1 known as a waterproof cover, but air  permeable membrane to use which is even Ventilation guaranteed.

DE 296 16 788 U1 also discloses waste with Compost help with rotting rents. Such rotten rents, also known as rotting boxes, have three sides Walls open and are made with so-called driving silos known in agriculture. Through the side walls the Rottenmiete is essentially space-saving render and easier to fill or empty. Exactly just like with the stacked waste the rotten rent with a water vapor and air passage covered with tarpaulin. The tarpaulin is applied here by a cantilever arm attached to a frame is pivotally arranged, so it is relatively expensive.

The object of the invention is therefore to provide a method ben, for example with the compost heap on simple Way can be covered.

This object is achieved in that the compost heap a plastic in liquid ger form is applied, the one after hardening the plastic film covering the compost heap forms. According to the invention, the coverage is simple cher way by applying a liquid plastic. A compost or garbage heap can thus in simple white se quickly and easily, especially sealed be, which at least causes unpleasant odors largely prevented and also ensured who  that germs, spores, bacteria etc., with which the covered good is contaminated, not to the reverse exercise. In the reverse way, too that bacteria, etc. get to the good from the outside.

Depending on the application, different plastics used with which the goods are then required fair, for example, air permeable or airtight, can be closed fluid-tight, germ-tight, etc. Ins it is special when covering compost heaps expedient in a biodegradable plastic liquid form to use, because then no doors later more of the goods covered is required.

Additives can advantageously be added to the plastic be admixed, which the through the plastic film support the intended purposes. For example the plastic contains a disinfectant, which germs, bacteria contained in the goods to be disposed of etc. kills. In the same way, surfactants in the plastic may be included.

Essential oils can also be added to the plastic be so that not by applying the plastic only unpleasant odors can be prevented, son which also spreads a pleasant fragrance for the user becomes.

Art can be used to kill and keep vermin away sulfur must still be added.  

The plastic can also contain an adhesive to the Liability of the plastic film to the covered goods to ver improve. If desired, the plastic film of the Being able to pull off covered goods can also Non-stick agents can be contained in the plastic Adherence of the plastic film to the covered goods ver prevent. The plastic can also contain a dye through which, for example, the type of covered Guts can be labeled.

The liquid plastic is used for hygienic reasons expediently up on the pile to be covered sprays, but any other type of application is also conceivable.

For applying the plastic film to larger areas such as fields, can be a mobile sprayer gene are used, as they are also used for the application of whose liquids are used. To cover only smaller piles such as compost piles a spray can can be used, as in the case of lying figure is shown.

The spray can 1 has essentially the same basic structure as conventional spray cans for hairspray etc. with a container 2 which has an outlet opening 3 in the form of a nipple projecting upwards above the container 2 on its upper side, and a spray head 4 , which is attached to the nipple and provided with a nozzle 5 . The container 2 contains liquid plastic 6 as spray material, to which a propellant is added in order to generate the pressure required for spraying. Alternatively, a pump can also be provided in a likewise known manner, by means of which an overpressure can be generated in the container 2 . The plastic is selected so that it hardens after spraying and forms a plastic film on the sprayed object.

On the outside of the container 2, a smaller, solvent medium 7 containing container 8 is attached, which if connectable to the nozzle 5 , in addition to and / or alternatively to the liquid plastic 6, the solvent 7 of the nozzle 5 is supplied and through this spray. This creates the possibility to clean the nozzle 5 before and / or after each spraying of plastic material 6 with the solvent or to dilute it with the plastic while spraying it.

To connect the nozzle 5 to the containers 2 , 8 , a distributor valve is provided, which can be moved from a closed position into different open positions by pressing down the spray head 4 . In a first position, in which the spray head 4 is only slightly depressed, a connection to the solvent container 8 is established and the connection to the plastic container 2 is interrupted, and in a second position, in which the spray head 4 is depressed further, a connection is made to the plastic container 2 and the connec tion to the solvent container 8 interrupted. This configuration ensures that the nozzle 5 is inevitably cleaned before and after each spraying of plastic, since when the spray head 4 is pressed down to reach the second position and later when the spray head 4 is released, the first position must always be passed through the nozzle 5 is connected to the solvent container 8 ter.

In addition, a third valve position is provided, which is achieved when the spray head 4 is fully depressed beyond the second position. In this third position, the nozzle 5 is connected to both containers 2 , 8 simultaneously, so that the sprayed plastic is diluted by the solvent.

The solvent container 8 is detachably attached to the plastic container 2 . This has the advantage that each loading container 2 , 8 can be replaced individually when it is empty. In addition, the possibility is created to add dyes to the solvent.

According to the present invention, the spray can 1 is used to spray a plastic material in liquid form on compost or rubbish heaps, which then cures to a plastic film covering the material. The plastic film prevents germs, bacteria, spores or the like, which contaminate the covered goods, escape to the environment or lead to odors.

The plastic film is expediently elastic to be prevent damage to the film.

The plastic can also contain enzymes, which the Decomposition process of the filled goods or the control biodegradable plastic.
