Definitions
- Devices of this type are therefore generally suitable for all systems, when two components are mixed in precisely metered amounts regardless of whether the two components are organic or inorganic in nature or whether they form foams or not.
- Systems of this type are generally recommended if two or more components are homogeneously mixed in less than 10 s, preferably 5 s or 1 s, and the mixed mass is applied to a base or into a cavity within seconds, after which it is reacted between the two components.
- the setting times of the component mixtures range between 10 s and 10 min. or a maximum of 60 min., preferably between 20 s and 5 min., so that rapid and continuous mixing of the two components is necessary and inexpensive.
- these devices which are preferably designed to be mobile, can also be attached in a stationary manner.
- Their stationary use will certainly be advantageous if, for example, comparatively small amounts of foam are required in short periods of time and the installation of an expensive, continuous component production device is not justifiable.
- the object of the invention is to describe a dosing method which is also suitable for aqueous suspensions which can contain abrasive substances and which can also be used on the spot and which allows an exact, widely continuous conveying and mixing of two or more components, which react to form a solid, especially a light material. This requirement must be met even if the corresponding component storage tanks are at a greater distance from the mixing unit.
- an at least predominantly inorganic, foamed mass can be produced by rapidly mixing a first component (A) and a second component (B).
- the first component (A) contains an acidic aqueous solution of predominantly polyvalent, preferably di- or tri-valent cations and phosphoric acid to form a phosphate, with 0.8 to 1.75 protons of the three-base phosphoric acid molecules being neutralized on average by the cations , in which solution one or more types of a granular, platelet or powdery filler are finely divided, a room temperature viscosity in the range from 2,000 mPa.s to 80,000 mPa.s, but preferably in the range from 6,500 mPa.s to 60,000 mPa .s, is advantageously adjusted by choosing the type, consistency and / or amount of the filler and / or its water content.
- the second component (B) contains an oxide, hydroxide or a polyvalent salt of a weak acid as a hardener and also a blowing agent which may also partially act as a hardener, such as a carbonate, which develops a gas, preferably CO2, under curing conditions, the component (B) preferably pasted or in the form of an aqueous suspension and the duration of the gas development process (rise time) in the range from 3 s to 10 min, advantageously by choosing the type of consistency and / or amount of the blowing agent. but preferably in the range from 5 s to 5 min.
- the prolonged setting process (setting time) advantageously by selecting the type, consistency and / or amount of the hardening substances, is set in the range from 10 s to 60 min, but preferably in the range from 20 s to 10 min.
- the process according to the invention which can in particular be carried out in a mobile manner, produces predominantly inorganic foamed light materials with adjustable density and temperature resistance of 1,100 ° C. and above with pore sizes of 0.5 mm to 3 mm and larger.
- The, in particular, but not exclusively, two aqueous components are preferably continuously and intensively mixed, the process parameters and the properties of the material produced being adjusted. It is crucial that the at least two components according to the invention are conveyed separately and / or independently of one another to the component mixing device, in particular continuously, and are discharged directly therefrom, in particular without further conduction or the like.
- the system is divided into two sub-assemblies, the two sub-assemblies from the large storage tanks (2), which are led to the construction site by a truck (1), for example, by high-pressure pumps (3) through separate hose lines (through the first sub-assembly). 4) to a second sub-assembly, which carries out the metering of the components (5).
- This sub-assembly consists, for example, of two or more smaller storage, pressure or dosing containers and is mobile or easily movable at the point where the foam is used.
- Fig. 2 shows, for example, a mobile dosing device (5) on wheels with two containers (9), in which in addition to the dosing process, the mixing process of one component can be carried out.
- the small mobile device consists of the components specified below.
- the basic device is a mobile device which is preferably located on wheels, which is easy to bring to construction sites, for example by motor vehicles, and is easy to maneuver in appropriate rooms.
- the two containers (9) for the two components, which can be subjected to pressures of 5 bar, 10 bar or more, can have a volume of 20, 30, 40, 50 and more liters.
- These openings can either be separated from one another or, for example, in the form of two openings, which can take on several functions. All openings can be closed, according to a preferred embodiment there is a dispersing disc (12) in the containers, which is driven directly by a motor (17) or by appropriate devices from a central drive unit and preferably can be pulled upwards with the drive the piston zone is removable).
- a floating piston (18) on the bottom, which can be moved by a pressure fluid.
- the hydraulic fluid is conveyed from a hydraulic fluid container (19) through a metering pump (20), the metering pump (20) being controlled by a drive motor and a gear (21) or being driven at a fixed speed.
- the two components are conveyed through the pressure fluids with the aid of the floating pistons (18) through separate hose lines (22) to a component mixing device (6), where they are processed by spraying or pouring.
- the movement of the piston (18) can also be achieved by means of suitable mechanical devices, for example spindle.
- a wash water container (23) is to be provided, from which wash water can be drawn into the containers (9) after the pressing process has ended by moving the piston (18) downwards via lines.
- containers are advantageously used which have a piston which can be acted upon on both sides by a switching process with the component delivered under pressure.
- the component pressed under pressure into the container presses the component mass on the other side of the piston out of the container to the mixing gun. If the entire component mass is expressed on one side, this process now takes place from the other piston side after a switching process. There is thus a simultaneous filling and squeezing process in the metering device in question.
- the control and adjustment of the piston speeds in the two component containers, for example, required for the regulated mass flow of the components can be achieved by a regulating device, such as a metering valve, or by a mechanical device that regulates the coordinated piston speed in the containers, for example a spindle or a rod , which connects the pistons to each other.
- a regulating device such as a metering valve
- a mechanical device that regulates the coordinated piston speed in the containers for example a spindle or a rod , which connects the pistons to each other.
- static mixers instead of a mixing gun (6), which enables further weight savings.
- safety and control devices which, for example, apply pressure to the piston (18) or suck the pressure medium through the metering pumps in the individual positions of the piston (18) in the container (9), for example at the top or bottom dead center of the Container, regulate or allow or prevent the switching on of the dispersing disc (12) in the individual stages of the use of the device and the manufacturing process.
- the manufacturing process of the inorganic foam from the two components takes place with the aid of a mixing and metering device according to FIG. 2 in the following way: 1. Introducing the liquid and solid raw materials into the container (9), optionally in a specific sequence with the dispersing disc (12) running.
- washing water can be sucked in from a container (23) to be provided by moving the pistons (18) downwards or by washing water being filled into the container (9) in another way.
- the squeeze lines (22) or dedicated lines are preferably used for this purpose. This is followed by a subsequent washing process for the containers (9), preferably using the dispersing disks (12).
- the pistons (18) are pulled down using the suction-switched metering pumps (20) and the containers (9) can be filled again with the raw materials for the next mixing process.
- the liquid and solid component components delivered in containers can only be filled into the component container (9) intended for them.
- This can be achieved, for example, by the fact that the individual lid openings of the containers (9) have different threads and thread dimensions, onto which only appropriately dimensioned funnels can be screwed, and into which only very specific forms of solid containers (square or rectangular packages) are inserted and opened can.
- Delivered liquid containers can also be provided with threads which can only be filled into the container (9) with the aid of intermediate hoses which are equipped with corresponding counter threads. It will also be beneficial to add additional differentiations, such as different labels and colors.
- the foams produced in this way by mobile or stationary systems based on phosphate are suitable as inorganic foamed insulation materials, for example as they can be used for facades or also for interior insulation, or as fire protection compounds for fire protection bulkheads, backfill frame backfills, etc. or also For inorganic, high-temperature resistant lightweight material linings that can be applied on the spot.
- the small device can, among other things, be made mobile in such a way that it is transported, for example, by a motor vehicle or even has wheels, or can be moved horizontally and vertically with the aid of a platform or a crane.
- the amounts of components A and B can either be regulated in an arbitrarily adjustable volumetric ratio, for example A: B or for example B: A of 100: 5, or preferably 100: 15 to 100: 100, or it can be, for example, by the choice the container dimensions, in particular the container diameter, fixed mixing ratios are provided in one device.
