Den foreliggende opfindelse angår en ny type mi neral fibre.The present invention relates to a new type of mineral fiber.
Traditionelle mineral fibre fremstilles ud fra i naturen forekommende materialer, hvorfor råmaterialeomkostningerne er relativt små.Traditional mineral fibers are made from naturally occurring materials, which is why the cost of raw materials is relatively small.
5 Sådanne kendte mineralfibre har typisk følgende sammensætning:Such known mineral fibers typically have the following composition:
SiOg ca. 45 vægt%SiOg approx. 45% by weight
AlgOj ca. 13,5 vægt% 10 ^e2^3 ca* vægt%AlgOj ca. 13.5 wt% 10 ^ e2 ^ 3 ca * wt%
CaO ca. 20,5 vægt%CaO approx. 20.5% by weight
MgO ca. 10,5 vægt%MgO approx. 10.5% by weight
TiO ca. 1,0 vægt%TiO approx. 1.0% by weight
NagO+KgO ca. 2,5 vægt% 15NagO + KgO ca. 2.5% by weight 15
De kendte mineral fibre udmærker sig ved at have en stor temperatur-bestandighed, men de påvirkes kun i ringe grad af saltopløsninger.The known mineral fibers are distinguished by their high temperature resistance, but they are only slightly affected by saline solutions.
De nedbrydes derfor meget langsomt, når de f.eks. efter brug deponeres på lossepladser og andre steder i det fri.Therefore, they degrade very slowly when, e.g. after use, deposit at landfills and other places outdoors.
2020
I beskrivelsen til NO patentansøgning nr. 874323 (Manvi Ile Corporation) er der omtalt uorganiske fibre, som tjener til at erstatte traditionelle mineraluldfibre og som udover Si02, CaOIn the specification of NO Patent Application No. 874323 (Manvi Ile Corporation), inorganic fibers are mentioned which serve to replace traditional mineral wool fibers and which in addition to SiO 2, CaO
indeholder MgO i en mængde på 0,1-30 vægt% og AlgO^ i en mængde på 25 0-10 vægt%. Ifølge ovennævnte patentansøgning er de nævnte fibre, hvis hovedkendetegn er, at de har et forholdsvis lavt indhold af AlgOg, betydeligt mere opløselige end traditionelle mineralfibre i saltopløsninger, f.eks. i den såkaldte Gamble's opløsning d.v.s. en vandig opløsning indeholdende følgende salte i opløst tilstand: 30contains MgO in an amount of 0.1-30% by weight and AlgO4 in an amount of 0-10% by weight. According to the aforementioned patent application, said fibers, whose main feature is that they have a relatively low content of AlgOg, are considerably more soluble than traditional mineral fibers in saline solutions, e.g. in the so-called Gamble's solution, i.e. an aqueous solution containing the following dissolved salts: 30

En væsentlig ulempe ved de kendte opløselige fibre er, at de fremstilles ud fra relativt dyre oxider og ikke ud fra i naturen forekommende råmaterialer.A major disadvantage of the known soluble fibers is that they are made from relatively expensive oxides and not from raw materials present in nature.
5 Hertil kommer, at nogle af de kendte fibre har en relativt ringe varmebestandighed, hvorfor de ikke kan anvendes ved høje brugstemperaturer.In addition, some of the known fibers have a relatively poor heat resistance, so they cannot be used at high operating temperatures.
Det har overraskende vist sig, at der ud fra i naturen forekommende 10 råmaterialer og andre billige råmaterialer kan fremstilles mineral-fibre, der har en betydelig større opløselighed i saltopløsninger end de ovenfor nævnte kendte mineralfibre og som samtidig udviser en acceptabel varmebestandighed.Surprisingly, it has been found that, from nature, 10 raw materials and other inexpensive raw materials can be prepared mineral fibers which have a significantly greater solubility in salt solutions than the above-mentioned known mineral fibers and which at the same time exhibit an acceptable heat resistance.
15 Mineral fibrene ifølge opfindelsen er ejendommelige ved, at de har følgende sammensætning:The mineral fibers of the invention are characterized in that they have the following composition:

Mineral fibre med den ovenfor angivne sammensætning kan fremstilles 30 ud fra i naturen forekommende råmaterialer og andre lettilgængelige og billige materialer, såsom affaldsprodukter fra mineraluldfrem-stilling og glasproduktion. Eksempler på sådanne råmaterialesammensætninger er anført i tabel I.Mineral fibers of the above composition can be prepared from naturally occurring raw materials and other readily available and inexpensive materials such as mineral wool manufacturing and glassmaking waste products. Examples of such raw material compositions are listed in Table I.

En fiberprøve ifølge NO patentansøgning nr. 874323 underkastedes en tilsvarende undersøgelse. Fibrene havde følgende sammensætning:A fiber sample according to NO Patent Application No. 874323 was subjected to a similar examination. The fibers had the following composition:

6 fibrene ifølge opfindelsen.6 according to the invention.
Han kunne befrygte, at mineralfibre med en relativ stor opløselige-hed i saltopløsninger ville være varmefølsomme og at de følgelig 5 ikke er anvendelige ved høje brugstemperaturer og ikke har den nødvendige brandmodstandsdygtighed. Forsøg har imidlertid vist, at denne frygt er ubegrundet, når det gælder mineralfibrene ifølge opfindelsen.He could fear that mineral fibers with a relatively high solubility in saline solutions would be heat sensitive and that, consequently, they are not usable at high operating temperatures and do not have the necessary fire resistance. However, tests have shown that this fear is unfounded with regard to the mineral fibers of the invention.
10 Forsøgene udførtes med mineral fiberprøver med en vægt på fra 0,5 til 1 g. Disse prøver anbragtes på en ildfast plade, som derpå indsattes i en ovn, der var forvarmet til en givet temperatur. Efter 30 mi ns. ophold ved denne temperatur blev fiberprøverne udtaget af ovnen og undersøgt. Hvis fibrenes dimensioner, struktur og elasticitet var 15 uændret, toges dette som udtryk for, at fibrene var bestandige ved den pågældende temperatur.The tests were performed with mineral fiber samples weighing from 0.5 to 1 g. These samples were placed on a refractory plate which was then inserted into an oven preheated to a given temperature. After 30 mi ns. At this temperature, the fiber samples were taken from the oven and examined. If the dimensions, structure and elasticity of the fibers were unchanged, this is taken as an indication that the fibers were resistant to the temperature in question.
Hvis det konstateredes, at fibrene var sprøde (sintrede), underkastedes en ny prøve en tilsvarende behandling ved en temperatur, som 20 var 25°C lavere end den først anvendte.If the fibers were found to be brittle (sintered), a new sample was subjected to a similar treatment at a temperature 20 ° C lower than first used.
Forsøget gentoges om nødvendigt efter en yderligere temperatursænkning, indtil fibrene forblev uændrede.If necessary, the experiment was repeated after a further decrease in temperature until the fibers remained unchanged.
25 Ved undersøgelse af de i tabel II angivne mineral fibre ifølge opfindelsen (prøve 3-6), konstateredes at de alle var bestandige ved en temperatur på over 750°C, hvilket svarer til temperaturbestan-digheden for ovennævnte mineral fiberprøve ifølge NO patentansøgning nr. 874323.Upon examination of the mineral fibers of the invention listed in Table II (Examples 3-6), it was found that they were all resistant to a temperature greater than 750 ° C, which corresponds to the temperature resistance of the above-mentioned mineral fiber sample according to NO patent application no. 874,323th
