Description

Oppfinnelsen angår et råemne for en bygningsplate på gipsbasis som fremstilles i overensstemmelse med opprullingsmetoden, hvilket råemne inneholder som bærefibre for dets våtmasse malte cellulose- og/eller avfallspapirfibre, som bindemiddel gips samt andre tilslutningsdeler, blant annet armeringsfibre. The invention relates to a blank for a gypsum-based building board which is produced in accordance with the roll-up method, which blank contains as carrier fibers for its wet mass milled cellulose and/or waste paper fibers, as a binder gypsum and other connecting parts, including reinforcing fibers.

Fra GB-patentansøkning 2.051.169 er det kjent en fremgangsmåte for fremstilling av et råemne for en .asbestffi bygningsplate på gipsbasis ved opprullingsmetoden, hvilket råemne inneholder regnet på totalvekten av dets tørrfeubstans 70-9 5% gips som halvhydrat og en malingsgrad på 30-70°SR(Schopper-Riegler) brutte cellulosefibre og/eller tilsvarende avfallspapir, samt dessuten armerings- og fyllstoffibre samt tilsetningsstoffer. From GB patent application 2,051,169, a method is known for the production of a raw material for an asbestos-based building board on a gypsum basis by the rolling method, which raw material contains calculated on the total weight of its dry matter 70-9 5% gypsum as hemihydrate and a grinding degree of 30- 70°SR (Schopper-Riegler) broken cellulose fibers and/or equivalent waste paper, as well as reinforcing and filler fibers and additives.

Ved den nevnte metoden har man imidlertid ikke kunnet fremstille slike plater med ønsket kapasitet. Årsaken til dette er konstatert å være massens dårlige til-pasningsevne, dvs. at den har en tendens til å oppvise egen-skaper av snarere en væske med lav viskositet enn en stabil masse. Massens filtreringsegenskaper er heller ikke til-fredsstillende, hvilket betyr at for mye fast substans absorberes med vannet til opprullingsmaskinens (Hatschek) filt og ledes derfra med vannet bort fra prosessen. Sub-stansen som setter seg fast i filten forkorter også maskinens brukstid, noe som fører til et for stort antall driftsstans. With the aforementioned method, however, it has not been possible to produce such plates with the desired capacity. The reason for this has been ascertained to be the mass's poor adaptability, i.e. that it tends to display properties of a low-viscosity liquid rather than a stable mass. The filtration properties of the pulp are also not satisfactory, which means that too much solid substance is absorbed with the water to the reeling machine's (Hatschek) felt and is led from there with the water away from the process. The substance that gets stuck in the felt also shortens the machine's service life, which leads to an excessive number of downtimes.

Ved forsøk på å unngå nevnte ulemper har man funnet at man med metoden ifølge oppfinnelsen, der det til gips-massen tilsettes en liten mengde hydraulisk herdende sement med maksimalt 30% av totalvekten av massens tørrsubstans, oppnår ønsket kapasitet. Man har også funnet at av-ledningsvannet derved blir renere, at antallet driftsstans synker og at filtens livslengde stiger. Massen oppviser også med hensyn til sin struktur ønsket jevn kvalitet. Resultatet er betydelig bedre enn i fremgangsmåten ifølge den nevnte britiske ansøkning. In an attempt to avoid the aforementioned disadvantages, it has been found that with the method according to the invention, where a small amount of hydraulically hardening cement is added to the gypsum mass with a maximum of 30% of the total weight of the dry substance of the mass, the desired capacity is achieved. It has also been found that the drainage water thereby becomes cleaner, that the number of downtimes decreases and that the life of the filter increases. The pulp also exhibits the desired uniform quality with regard to its structure. The result is significantly better than in the method according to the aforementioned British application.

Ved forsøk som er utført på ferdige plater fremstilt med fremgangsmåten ifølge oppfinnelsen har det dessuten overraskende vist seg at platenes fuktbestandighet, bøyefasthet, stivhet og flatehårdhet har økt mere enn ventet. Dessuten minsker korrosjonseffekten når massens pH stiger. Disse fordeler har man oppnådd uten ved bruk av gips å tape den forbedrede brannsikkerheten på plater fremstilt ved opprullingsmetoden, der malte cellulosefibre an-vendes som bærefibre. In tests carried out on finished boards produced with the method according to the invention, it has also surprisingly been shown that the boards' moisture resistance, bending strength, stiffness and surface hardness have increased more than expected. Furthermore, the corrosion effect decreases when the pH of the mass rises. These advantages have been achieved without, by using plaster, losing the improved fire safety of boards produced by the coiling method, where ground cellulose fibers are used as carrier fibres.

På eksperimentell måte har man funnet at et optimalt resultat i høy grad er avhengig av cellulosefibrenes riktige malingsgrad i forhold til den aktuelle sement-mengden, som igjen ganske nøyaktig bør tilpasses i forhold til gipsmengden. In an experimental way, it has been found that an optimal result is highly dependent on the cellulose fibers' correct degree of grinding in relation to the amount of cement in question, which in turn should be adjusted quite precisely in relation to the amount of plaster.

Oppfinnelsens kjennetegn fremgår av det etter-følgende patentkrav. Ifølge dette krav inneholder råemnet 30-85 vekt% gips i CaS04 . 1/2 H20-form, maksimalt 30% hydraulisk herdende sement, 3-30% med malingsgrad 20-80°SR malte cellulose- og/eller avfallspapirfibre, The characteristics of the invention appear in the following patent claim. According to this requirement, the raw material contains 30-85% by weight of gypsum in CaS04. 1/2 H20 form, maximum 30% hydraulically hardening cement, 3-30% with paint grade 20-80°SR ground cellulose and/or waste paper fibers,

samt som andre tilsetningsstoffer i slike mengder som an-gitt i patentkravet. Den hydraulisk herdende sementen kan f.eks. være Portlandsement. as well as other additives in such quantities as stated in the patent claim. The hydraulically hardening cement can e.g. be Portland cement.

Av den første vannrette linjen fremgår resultat som er oppnådd for en bygningsplate med en sammensetning ifølge GB-ansøkning 2.051.16 9, og i de følgende vannrette linjene fremgår resultater som er oppnådd for en plate med en sammensetning ifølge foreliggende oppfinnelse.
