Description

Fremgangsmåte til fremstilling av plane eller Procedure for the production of plane or

krumme skive- eller veggelementer eller lignende. curved disc or wall elements or the like.

Foreliggende oppfinnelse angår framstilling av plane The present invention relates to the production of a plane

eller krumme skive- eller veggelementer eller lignende for f.eks. beholdere, siloer, rør, vegger, tak, gulv eller andre bygnings-elementer. Oppfinnelsen har særlig til hensikt å fremskaffe slike elementer som er holdbare, tette, slitesterke og relativt billige i fremstilling. Ifølge oppfinnelsen oppnås dette ved de fremstillings-trinn som fremgår av krav 1. or curved disk or wall elements or the like for e.g. containers, silos, pipes, walls, roofs, floors or other building elements. The invention particularly aims to provide such elements which are durable, tight, durable and relatively cheap to manufacture. According to the invention, this is achieved by the manufacturing steps that appear in claim 1.

Ifølge et utførelseseksempel med henvisning til tegningen, der According to an embodiment with reference to the drawing, there

fig. 1 viser et snitt av et lag av elementet under fremstillingen, fig. 1 shows a section of a layer of the element during manufacture,

fig. 2 dette lag ferdig fremstilt og fig. 2 this team fully prepared and

fig. 3 en senere fase i fremstillingen, kan fremstillingen skje på følgende måte: fig. 3 a later phase in the production, the production can take place in the following way:

På et fortrinnsvis plant, ikke absorberende underlag 1 (f.eks. av rustfri plate), behandlet med slippmiddel, utbres ved hjelp av sjaber 2 eller på annen.måte et fortrinnsvis jevnt lag 3 av en blanding av flytende plastbindemiddel og faste partikler. Mengden bindemiddel skal overstige hulromsvolumet mellom de faste partiklene. Etterat utbredningen har skjedd, sedimenterer de faste partiklene 4 mot underlaget ( fig. 2) og samtidig stiger luftbobler opp mot flaten. A preferably even layer 3 of a mixture of liquid plastic binder and solid particles is spread on a preferably flat, non-absorbent substrate 1 (e.g. of stainless plate), treated with a release agent, by means of a scraper 2 or in another way. The amount of binder must exceed the void volume between the solid particles. After the spread has taken place, the solid particles 4 sediment against the substrate (fig. 2) and at the same time air bubbles rise to the surface.

Den tid det tar før sedimenteringen har skjedd og luft-boblenes vandring mot flaten avsluttet, er blant annet avhengig av de faste partiklenes tetthet og størrelse, samt det flytende plast-bindemidlets viskositet og flatespenning. Overskudd av bindemiddel stiger opp til flaten og danner der et overflatelag 5- Overflate- The time it takes before sedimentation has occurred and the air bubbles' migration towards the surface has ended depends, among other things, on the density and size of the solid particles, as well as the viscosity and surface tension of the liquid plastic binder. Excess binder rises to the surface and forms a surface layer there 5- Surface-

laget 5 sammenføres nå "med et absorberende lag 6, f.eks. tverrvell, (fig. 3)j som nedtrykkes i overflatelaget, slik at dette, det vil si overskuddet av det flytende bindemiddel suges inn i det absorberende laget eller tverrvellen 6. Ovenpå tverrvellen 6 anbringes nå even-tuelt et på en opp- nedvendt plate 7 med slippmiddel anbragt lag 8, lignende lagene 3>5 meci overskuddsplasten 5 vendt mot tverrvellen 6, slik at denne absorberer plasten 5. Etterat platen er herdet fåes et fast, hårdt produkt. the layer 5 is now joined "with an absorbent layer 6, e.g. cross well, (fig. 3)j which is pressed down into the surface layer, so that this, that is, the excess of the liquid binder is sucked into the absorbent layer or cross well 6. On top of the transverse roller 6, a layer 8 placed on an upside-down plate 7 with a release agent is now placed, similar to the layers 3>5, with the excess plastic 5 facing the transverse roller 6, so that it absorbs the plastic 5. After the plate has hardened, a firm, hard product.

Mellom platene 1 og 7 finnes, slik som det fremgår av Between plates 1 and 7 is found, as is evident from

fig. 3> distanselister 9 som med tilstrekkelig nøyaktighet gir riktig tykkelse og parallellitet, samt planhet på det ferdige produktet. fig. 3> distance strips 9 which with sufficient accuracy provide the correct thickness and parallelism, as well as flatness of the finished product.

For fremstilling av krumme konstruksjoner, f.eks. seg-menter til sylindre, utbres overflatelaget 3 ifølge ovenstående på formbare plater på et plant underlag. Etterat laget 3 nar sedimentert, utbres et mellomsjikt eller absorberende sjikt av sand blandet med et underskudd av polyester med herder til ønsket tykkelse på den ene platen. Deretter formforandres platen til ønsket radie. Etterat dette er fullført, legges det på den andre platen anbragte overflatelaget på oversiden av det nevnte absorberende lag. Det absorberende lags absorbsjonsevne må være slik at det i passende mengde suger opp overskuddet av det flytende bindemiddel. Dersom det absorberende lag har for stor absorbsjonsevne, uttynnes den sedimenterte delen 4-> hvilket medfører at bindingen mellom lagene blir for liten. Dersom absorbsjonsevnen ikke er tilstrekkelig, vil det bli et lag igjen mellom det absorberende laget 6 og det sedimenterte laget \. Ved det flytende bindemiddels overgang til fast form, kommer da det på denne måte oppståtte mellomlag til å ha en større krympning enn de to øvrige lagene, der krympingen er praktisk talt eliminert. Derved oppstår krympningsspenninger som kan ytre seg i krakelering og/eller formforandringer. For the production of curved constructions, e.g. segments into cylinders, the surface layer 3 is spread according to the above on malleable plates on a flat surface. After the layer 3 has settled, an intermediate layer or absorbent layer of sand mixed with a deficit of polyester with hardener is spread to the desired thickness on one plate. The plate is then reshaped to the desired radius. After this has been completed, the surface layer placed on the second plate is placed on top of the aforementioned absorbent layer. The absorbency of the absorbent layer must be such that it absorbs the excess of the liquid binder in a suitable amount. If the absorbent layer has too much absorbency, the sedimented part 4-> becomes thinner, which means that the bond between the layers becomes too small. If the absorption capacity is not sufficient, a layer will remain between the absorbent layer 6 and the sedimented layer \. When the liquid binder changes to solid form, the intermediate layer created in this way will have a greater shrinkage than the other two layers, where the shrinkage is practically eliminated. This creates shrinkage stresses which can manifest in cracking and/or changes in shape.

Det flytende bindemiddel kan f.eks. utgjøres av en isoftal-,ftal-,bisfenol- eller andre polyestre med herder, f.eks. i form av hexametylentetramin. Disse stoffene benevnes bare som eksempler. The liquid binder can e.g. consists of an isophthalic, phthalic, bisphenolic or other polyester with a hardener, e.g. in the form of hexamethylenetetramine. These substances are named as examples only.

De faste partiklene kan f.eks. utgjøres av sand, f.eks. med en middels kornstørrelse på 0,15 ^> av typen Baskarpsand Nr. 7> sementkornformet slagg, metall- og jernpulver m.m. Det absorberende laget kan f.eks. utgjøres av en blanding av sand med underskudd av polyester eller av betong eller bølgepappmateriale ("tverrvell"). The solid particles can e.g. consists of sand, e.g. with an average grain size of 0.15 ^> of the type Baskarpsand No. 7> cement grain-shaped slag, metal and iron powder, etc. The absorbent layer can e.g. consists of a mixture of sand with a deficit of polyester or of concrete or corrugated cardboard material ("cross-wall").
