Abstract
The invention relates to a method for the production of foamed glass granulate, comprising the following steps: an aqueous glass binder slop which contains water is prepared at room temperature, and a propellant and a glass binder is prepared in an additional container, glass powder, preferably, old glass powder is added to the glass binder slop in order to form a humid, stirrable glass preparation, the thus formed glass preparation is homogenised, is added to a stirring container and is stirred during a stirring time which is between 2 and 6 hours in order to at least partially decompose the glass components, additional glass powder is added to the glass preparation in a granulate mixer in order to form granulate green bodies which are then dried and are foamed in order to form foamed glass granulate particles.
Description
The present invention relates to-kind prepare the method for foam glass particle with claim 1 feature that preamble is put down in writing.
The method for preparing foam glass particle is disclosed among applicant's document EP 0052693B1, EP0484643A1 and the EP0678482B1.In these methods, preparation comprises water, whipping agent and as the hydrated glass binding agent slurry of the water glass of glass binder in preparation jar in known manner.Need use the about 80 ℃ hot water that needs high energy input to heat for this reason.Glass powder is joined in this glass binder slurry for preparing in the jar, and the formation water ratio is the frit that the humidity of 31-45% can stir.After all glass powder adds, this frit mixed making it even in about 5 minutes.Subsequently this frit is put into stirred pot, in stirred pot, frit stirred 50-80 minute so that glass ingredient partial melting at least as hold-up vessel.After the stirring, use volume pump that frit is sent in the continuous granulation mixing tank, be metered into extra glass powder therein so that the water ratio of frit is reduced to about 18-18.5%.Subsequently the granulation green compact that form are for example carried out drying and foaming in the rotary kiln in the granulation mixing tank, thereby under about 800 ℃ temperature, forming foam glass particle.
The shortcoming of currently known methods is when water being added thermosetting hydrated glass caking agent slurry, and in order to carry out described " hot melt ", it needs the high energy input.Consider the comprehensive application in multiple product, in order to make its resistance to compression and mechanically stable as much as possible, people also wish to make the foam glass particle of preparation firm as far as possible in principle.
Based on this problem, the objective of the invention is to improve known foam glass particle production method and obtain more high-intensity granulation particle in the hope of using energy still less.
The feature that this purpose is put down in writing by claim 1 characteristic is achieved, and it mainly comprises what is called " sloppy heat " mode of following long-time stirring.That is to say according to the present invention not have energy requirement fully water is heated thereby under about room temperature, add in order to the water that forms the glass binder slurry.For this is compensated, the churning time in the stirred pot is adjusted to 2-6 hour.Since can be by the quite long churning time of using corresponding big stirred pot or a plurality of stirred pot to compensate in process of production, melt on the glass powder particles surface, causes forming a kind of soup compound or gel at particle surface.This makes and improved intergranular mutual adhesion when forming the granulation green compact, thereby has improved the intensity of the actual foam glass particle that forms after the foaming.About this point, experiment shows with the foam glass particle of producing in a conventional manner to be compared, and the present invention can obtain about 30% strength enhancing.
Put down in writing the preferred parameter and the further step of the inventive method in the dependent claims, following specific embodiments has been described present method in more detail.With the water under 970 liters of room temperatures, 900 kilograms as the hot water glass of glass binder and 45 kilograms for example traditional whipping agent of carbohydrate, Manganse Dioxide or yellow soda ash place preparation jar and mix in short-term.The temperature that depends on water glass, the temperature of glass bond slurry is about 31-40 ℃.
The recovery glass powder that is 0.1mm with 1330 kilograms of particle diameters added in approximately 30-40 minute time, was the frit of 39-45% thereby form the moist water ratio that can stir.Make it even in 5 minutes this frit stir about, put into the not big stirred vessel of heating subsequently.The frit in the stirred vessel in batches then, churning time between 2-6 hour, preferably about 4-5 hour so that the glass ingredient at least in the partial melting frit.Form the activity glass powder particles thus, because particle surface formed gel coat, this particle can be guaranteed the particle that forms thereafter " oven dry " fully.
After aforementioned stirring cycle, frit enters in the continuous granulation mixing tank via volume pump, mixes more glass powder therein and forms the granulation green compact.The extra granulation green compact that particle diameter is preferably 0.25-0.5mm add as the granulation nucleator, based on frit and to add its weight content of glass powder gross weight be about 4-8%.
The granulation green compact that will prepare thus subsequently are sent to and carry out granulation on the pelletizing disks and make it to have bigger median size.To make its remaining water ratio be 0.1% and be divided into the different-grain diameter grade by screening before foaming in the granulating and drying device granulation green compact to be carried out drying.Typical particle diameter grade is diameter range for example as described below: 0.25-0.5mm, 0.5-1.0mm, 1.0-2.0mm, 2.0-4.0mm and 4.0-8.0mm.
Corresponding particle foams under about 790 ℃ temperature in rotary kiln subsequently in a conventional manner.
