Description
15 20 25 30 35 H0 7807539-7 ... _ _. ...._,,...__ .._-_._ . ..-__ ... ligt uppfinningen ett stelt element, vilket medger att elementet kan användas för t.ex. ingjutning i betong, dvs. tål det tryck be- tongen utsätter elementet för. I detta stela material kan dessutom spikas och skruvas. Elementet är dessutom frostbeständigt och fry- ser icke sönder. 15 20 25 30 35 H0 7807539-7 ... _ _. ...._ ,, ...__ .._-_._. ..-__ ... according to the invention a rigid element, which allows the element to be used for e.g. casting in concrete, ie. withstands the pressure to which the concrete is subjected. In addition, this rigid material can be nailed and screwed. The element is also frost-resistant and does not freeze.
Elementet enligt uppfinningen består således av det billiga g avfallsmaterialet bark, företrädesvis furu- eller bokbark, och ett lämpligt limämne, t.ex. karbamidharts.The element according to the invention thus consists of the cheap and waste material bark, preferably pine or beech bark, and a suitable adhesive, e.g. urea resin.
Före själva framställningen av ett element sönderdelas, t.ex. rivs, barken till företrädesvis 8-30 mm3 styokevolym. Barkstyokena torkas därefter till åtminstone 25% fuktighet, för den händelse fukt- halten skulle vara högre.Before the actual production of an element decomposes, e.g. torn, the bark to preferably 8-30 mm3 styoke volume. The bark styokene is then dried to at least 25% moisture, in case the moisture content would be higher.
I nästa framställningssteg pålägges barkstyckena ett tunt skikt av limämnet. Detta sker företrädesvis i en tumlare, t.ex. enstumlar- konstruktion av det slag som visas i genomskärning på bifogade rit- ning och vilken konstruerats speciellt för detta ändamål. I den ro- terande, med slät inre mantel utformade tumlaren 1 frammatas bark- styckena medelst väggar 2, varvid den under rotationen befintliga övre väggen styr barkstyckena att falla såsom visat med pil A förbi spraystrålar av limämnet från ett stationärt sprutrör 3. Genom denna duschning av barkstyckena säkerställas att de blir åtminstone i hu- vudsak helt belagda med ett tunt skikt av limämnet.In the next manufacturing step, a thin layer of the adhesive is applied to the bark pieces. This is preferably done in a porpoise, e.g. a stumbling block construction of the type shown in section in the accompanying drawing and which has been specially designed for this purpose. In the rotating, smooth inner sheath tumbler 1, the bark pieces are advanced by means of walls 2, the upper wall present during the rotation guiding the bark pieces to fall as shown by arrow A past spray jets of the adhesive from a stationary spray tube 3. Through this showering of the bark pieces it is ensured that they are at least substantially completely coated with a thin layer of the adhesive.
De limskiktsförsedda barkstyckena formsättes därefter och pres- sas till önskad elementdimension samt utsättes för elektronisk strål- ningsuppvärmning, varvid fixering av elementet sker.The glue-layered bark pieces are then molded and pressed to the desired element dimension and subjected to electronic radiation heating, whereby the element is fixed.
Strålningsuppvärmningen äger härvid rum i ett aggregat av elak-_ tron- eller mikrovâgtyp. Ett elektronaggregat med högfrekvent strål- ning har visat sig vara billigare att framställa än ett mikrovågagg- regat, eftersom elektronaggregatet tillskillnad från mikrovågaggrega- tet ej behöver byggas in.The radiant heating takes place in a unit of the electron, electron or microwave type. An electron unit with high-frequency radiation has proven to be cheaper to produce than a microwave unit, since the electron unit, unlike the microwave unit, does not need to be built in.
I ett elektronaggregat riktas lämpligen strålningen mot det formsatta elementets ena plana sida och härvid samtidigt över hela sidan, genomgår elementet och återkastas av ett mot elementets mot- satta plana sida anliggande underlag. I ett mikrovågaggregat riktas lämpligen strålningen mot det formsatta elementets båda plana sidor.In an electron assembly, the radiation is suitably directed towards one flat side of the shaped element, and at the same time over the entire side, the element passes through and is reflected by a surface abutting the opposite flat side of the element. In a microwave unit, the radiation is suitably directed towards both flat sides of the molded element.
Pressningen av barkstyckena till önskad dimension utföres före- trädesvis i aggregatet, men kan även ske separat varefter den pres- sade produkten transpoteras med kvarhállen pressning in i aggregatet. g Jämfört med en konventionell hydraulisk väemepress sker uppvärm- ningen enligt uppfinningen cza 15 gånger snabbare. Vid hydraulisk 10 15 20 limämne. 7807539-7 värmepress trycks ångan in mot centrum under fortgående fixering av produkten med åtföljande risk för sönderdelning i element när press- trycket upphör. Vid en uppvärmning enligt föreliggande uppfinning i ett elektronaggregat går strålarna mot sidan anliggande mot det strål- ningsbrytande underlaget. Fixeringen börjar vid strâlningsingången oeh.fortsätter mot nämnda sida allteftersom ångan går ut. Vid en upp- värmning enligt föreliggande uppfinning i ett mikrovâgaggregat går mikrovågstrålarna in mot centrum och fixeringen börjar där för att sedan fortsätta ut mot kanterna allteftersom ångan går utåt. Försök har visat att en uppvärmning i enlighet med uppfinningen i hög grad undanröjer risk för sönderdelning och sprickbildning av det färdiga elementet.The pressing of the bark pieces to the desired dimension is preferably carried out in the unit, but can also take place separately, after which the pressed product is transported with sustained pressing into the unit. g Compared to a conventional hydraulic hydraulic press, the heating according to the invention takes place approximately 15 times faster. For hydraulic 10 15 20 adhesive. 7807539-7 heat press, the steam is pressed towards the center during continuous fixing of the product with the attendant risk of decomposition in elements when the press pressure ceases. In a heating according to the present invention in an electron assembly, the rays go to the side abutting against the radiation-refractory substrate. The fixation starts at the radiation input oeh. Continues towards said side as the steam goes out. In a heating according to the present invention in a microwave unit, the microwave jets go towards the center and the fixation starts there and then continues towards the edges as the steam goes outwards. Experiments have shown that a heating in accordance with the invention largely eliminates the risk of decomposition and cracking of the finished element.
Det pâsprutade limmet som sammanbinder barkstyckena leder även strålningsströmmen. Det eftersträvade tunna limskiktet har den för- delen att elementet blir lättare och ger bättre isolering. Dess- utom blir självfallet elementet billigare genom mindre åtgâng-av Ett element enligt uppfinningen erhåller beroende på det press- tryck den varit utsatt för?\-värden mellan 0,045 - 0,060. Erhållen tryckhâllfasthet svarande mot Ä 0,0H5 är 7 - 8 kg/cmz och för Å o,o6o wa 15 xg/cmg. eThe sprayed adhesive that connects the bark pieces also conducts the radiation current. The desired thin adhesive layer has the advantage that the element becomes lighter and provides better insulation. In addition, of course, the element becomes cheaper through less intervention. An element according to the invention obtains, depending on the pressure pressure to which it has been subjected, values between 0.045 and 0.060. The compressive strength obtained corresponding to Ä 0,0H5 is 7 - 8 kg / cmz and for Å o, o6o wa 15 xg / cmg. e
