Description
Foreliggende oppfinnelse vedrører behandling av partikkelformet materiale for dannelse av aggregater og angår spesielt dannelse av briketter. The present invention relates to the treatment of particulate material for the formation of aggregates and particularly relates to the formation of briquettes.
Den konvensjonelle metode for fremstilling av briketterThe conventional method for making briquettes
er ved blanding av det partikkelformede materiale, slik som trekull, malmpulver og lignende, med stivelse, molasse, malt mais, dekstriner, boraks, kalk, silisiumdioksyd eller andre binde- is by mixing the particulate material, such as charcoal, ore powder and the like, with starch, molasses, ground corn, dextrins, borax, lime, silicon dioxide or other binders
midler. Det spesielle bindemiddel som anvendes bestemmes ut fra sluttanvendelsen av brikettene eller de spesielle håndtering- og lagringsbetingelser, den nødvendige råstyrke og andre forhold. funds. The special binder used is determined based on the end use of the briquettes or the special handling and storage conditions, the required raw strength and other conditions.
I den metallurgiske industri viser en brikette fremstiltIn the metallurgical industry shows a briquette manufactured
fra stivelse utilfredsstillende ovnsegenskaper idet den har tendens til å sprenges med resulterende knusing av partikkelformede materiale, noen ganger i en slik utstrekning at.noe av dens effektivitet går tapt. I tillegg til dette har briketter bundet med stivelse liten motstandsdyktighet overfor vann og kan ikke tilfredsstillende lagres under åpen himmel eller holdes fuktig under behandling. from starch unsatisfactory furnace properties in that it tends to burst with resultant crushing of particulate matter, sometimes to such an extent that some of its efficiency is lost. In addition to this, briquettes bound with starch have little resistance to water and cannot be satisfactorily stored in the open air or kept moist during processing.
Formålet med foreliggende oppfinnelse er å tilveiebringe aggregater av partikkelformet materiale og spesielt briketter, The purpose of the present invention is to provide aggregates of particulate material and in particular briquettes,
som har overraskende forbedrede egenskaper i forhold til konvensjonelle aggregater eller briketter. which have surprisingly improved properties compared to conventional aggregates or briquettes.
Ifølge foreliggende oppfinnelse er det således tilveie-brakt en fremgangsmåte til agglomerering av partikkelformet materiale hvor dette materiale blandes"med en blanding av et konvensjonelt bindemiddel og et polymert materiale. According to the present invention, there is thus provided a method for the agglomeration of particulate material where this material is mixed with a mixture of a conventional binder and a polymeric material.
I den foretrukne form av oppfinnelsen utgjøres polymer-materialet hensiktsmessig av en stabilisert polymeremulsjon. In the preferred form of the invention, the polymer material suitably consists of a stabilized polymer emulsion.
I forbindelse med visse polymerer og visse anvendelserIn connection with certain polymers and certain applications
og forhold kan det også være nødvendig å benytte additiver, slikand conditions, it may also be necessary to use additives, such as
som fuktemidler, anti-skummeforbindelser og lignende.such as wetting agents, anti-foam compounds and the like.
Selv om det kan anvendes et bredt område med hensyn til forhold mellom bindemiddel og polymer, har man oppnådd overraskende gode resultater med hensyn til råstyrke, upåvirkelig-het overfor vann, forbedrede ovnsegenskaper og andre egenskaper, Although a wide range of binder to polymer ratios can be used, surprisingly good results have been achieved in terms of raw strength, water resistance, improved oven properties and other properties,
med forhold av.størrelsesorden 10 vektdeler. stivelse og en vekt-with ratios of the order of magnitude 10 parts by weight. starch and a weight-
del av en polymer.part of a polymer.
Kombinasjonen av bindemiddel og polymer bør være i om-The combination of binder and polymer should be in
rådet fra ca. 1 til ca. 20 vekt-% av det partikkelformede materiale, men det er åpenbart at den optimale mengde vil være avhengig av beskaffenheten av det partikkelformede materiale og av de egenskaper som er nødvendige. For en vanadiumoksyd-brikette kan mengden av stivelse i briketten være ca. 2%, mens polymeren kan være tilstede i en mengde på omkring 0,5%; for trekull ca. 5- advised from approx. 1 to approx. 20% by weight of the particulate material, but it is obvious that the optimum amount will depend on the nature of the particulate material and on the properties required. For a vanadium oxide briquette, the amount of starch in the briquette can be approx. 2%, while the polymer may be present in an amount of about 0.5%; for charcoal approx. 5-
10% stivelse og 1-3% polymer; og for krommalm mellom ca. 2 og 5% stivelse og 0,5-1,5% polymer. Et nyttig kriterium ved bestemmelse av den mengde av blandingen som skal anvendes, er å undersøke den minste mengde vann som må benyttes i forhold til de to kompo-nentene. 10% starch and 1-3% polymer; and for chrome ore between approx. 2 and 5% starch and 0.5-1.5% polymer. A useful criterion when determining the amount of the mixture to be used is to examine the smallest amount of water that must be used in relation to the two components.
De foretrukne monomerer som anvendes ved fremstilling avThe preferred monomers used in the production of
de benyttede emulsjoner er:the emulsions used are:
(a) vinylestere av en alifatisk syre med 1-18 karbonatomer, spesielt vinylacetat, vinylpropionat og vinyl-"Versatate". (b) akryl- og metakrylsyreestere av en alkohol med 1-18 karbonatomer, spesielt metylakrylat, etylakrylat, butylakrylat, 2-etylheksylakrylat og metylmetakrylat. (c) mono- og di-etylenisk umettede hydrokarboner, slik som styren og alifatisk diener, slik som butadiener. (a) vinyl esters of an aliphatic acid having 1-18 carbon atoms, especially vinyl acetate, vinyl propionate and vinyl "Versatate". (b) acrylic and methacrylic acid esters of an alcohol having 1-18 carbon atoms, especially methyl acrylate, ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate and methyl methacrylate. (c) mono- and di-ethylenically unsaturated hydrocarbons, such as styrene and aliphatic dienes, such as butadienes.
(d) umettede karboksylsyrer, slik som akrylsyre, metakryl-(d) unsaturated carboxylic acids, such as acrylic acid, methacrylic
syre, krotonsyre, fumarsyre og itakonsyre.acid, crotonic acid, fumaric acid and itaconic acid.
(e) umettede karboksylsyreestere av en alkohol inneholdende en ytterligere funksjonell gruppe, slik som glycidylmetakrylat, hydroksyetylakrylat og hydroksypropylakrylat. (f) vinylmonomerer, slik som akrylamid, akrylonitril, metylol-akrylamid og metakrylamid. (e) unsaturated carboxylic acid esters of an alcohol containing an additional functional group, such as glycidyl methacrylate, hydroxyethyl acrylate and hydroxypropyl acrylate. (f) vinyl monomers, such as acrylamide, acrylonitrile, methylol acrylamide and methacrylamide.
Polymerisasjonsinitiering kan skje ved hjelp av et hvert stoff som avgir frie radikaler, enten termisk eller kjemisk initisert. I den foretrukne form består initiatorsystemet av ammonium- eller kaliumpersulfat (peroksydisulfat) i kombinasjon med hydrogenperoksyd, for oppnåelse av en rimelig reaksjonshastig-het og god sluttlig omdannelse. Polymerization initiation can take place with the help of any substance that emits free radicals, either thermally or chemically initiated. In the preferred form, the initiator system consists of ammonium or potassium persulphate (peroxydisulphate) in combination with hydrogen peroxide, to achieve a reasonable reaction rate and good final conversion.
Andre bestanddeler som kan inkluderes i emulsjonen om-fatter molekylvekt-modifiseringsmidler (kjedeoverføringsmidler), elektrolytter, salter, myknere, oppløsningsmiddél, mindre mengder stabilisatorer (dispergerende kolloid eller overflate-aktivt middel) og lignende materialer som er velkjente innen emulsjonspolymerisasjon, så lenge de ikke forstyrrer de egenskaper som er ønsket i den sluttlige dispersjon. Other ingredients which may be included in the emulsion include molecular weight modifiers (chain transfer agents), electrolytes, salts, plasticizers, solubilizers, minor amounts of stabilizers (dispersing colloid or surfactant) and similar materials well known in the art of emulsion polymerization, as long as they do not interferes with the properties desired in the final dispersion.
Reaksjonstemperaturer for polymerisasjon kan være i om-rådet 5-95°C, fortrinnsvis 70-90°C. Reaction temperatures for polymerization can be in the range 5-95°C, preferably 70-90°C.
Eksempel 1Example 1
Briketter av vanadiumoksyd ble fremstilt i varierende forhold mellom stivelse og en polymer betegnet "SS100". Briquettes of vanadium oxide were produced in varying ratios of starch to a polymer designated "SS100".
I dette eksempel ble således et meget fint pulver forbedret ikke bare med hensyn til tørrstyrke, men også råstyrke. In this example, a very fine powder was thus improved not only with regard to dry strength, but also raw strength.
Eksempel 2Example 2
Der vannbestandighet og forbedret tørr- og våtstyrkeThere water resistance and improved dry and wet strength
er nødvendig sammen med forbedret ovnsstyrke,. har f.eks. stivelse, foruten at den er følsom overfor vann, tendens til å brekke ved ca. 1000°C. Blandinger med polymeremulsjon vil forbedre ovns-bestandigheten. Avhengig av anvendelsen kan man tilsette andre materialer som vil hjelpe bindingen ved meget høye temperaturer, is required along with improved furnace strength,. has e.g. starch, apart from being sensitive to water, tends to break at approx. 1000°C. Mixtures with polymer emulsion will improve oven resistance. Depending on the application, other materials can be added that will help the bond at very high temperatures,
men som ikke har noen virkning på egenskapene i kald tilstand, og slike stoffer er boraks, silisiumdioksyd og kalk. but which have no effect on the properties in the cold state, and such substances are borax, silicon dioxide and lime.
Forbedringer med hensyn til egenskapene hos trekull, har vist seg i blandinger og spesielt når det anvendes et forhold på 10 deler stivelse til 1 del polymer. Følgende resultater ble oppnådd med trekullpulver bundet i sylindriske briketter. Improvements with regard to the properties of charcoal have been shown in mixtures and especially when a ratio of 10 parts starch to 1 part polymer is used. The following results were obtained with charcoal powder bound in cylindrical briquettes.
I kromsand som trengte tilsetning av bindemiddel som In chrome sand that needed the addition of a binder such as
