Description
Oblasť techniky spôsobu cementu pri kt vlákna výroby stavebnín, stavebných s vláknitým plnidlom podľa oroa sa použije cement ako z buničiny, plastikové vláknaBACKGROUND OF THE INVENTION Field of the Cement Method at KT Fibers for Building Materials Building with Fiber Filler according to Oro, Pulp Cement, Plastic Fibers
Vynález sa týka dielcov a panelov 2 HaLschekového spôsobu, spoj i dl o a vlákr.a, ako a podobne, ako výstuž.The invention relates to parts and panels 2 of the Haschschek method, joints and fibers as well as the like as reinforcement.
Doterajší stav technikyBACKGROUND OF THE INVENTION
V známych stavebninách t voda alebo vlhkosť môžu byť najmä v lisovaných nerovnomerne, keď vysúšan i e alebo panelov rovnomerné, s miestami s väčšou vlhkosťou, v stavebných dielcoch alebo okrajovej oblasti.In known building materials, water or moisture can be particularly unevenly pressed when dried or panels are uniform, with places of higher humidity, in components or peripheral areas.
Toto vytvorenie trhlín je vynálezu je vytvoriť spôsob dielcov a panelov vyššie zabráni vzniku trhlin.This cracking feature of the invention is to provide a method of panels and panels above avoiding cracking.
ohoto druhu je problém v tom, že v priereze stavebnín a panelov, a paneloch, rozložené celom priereze stavebnín miesta sa striedajú čo môže spôsobovať vznik trhlín paneloch, predovšetkým v ich veľmi nevýhodné, takže úlohou výroby stavebnín, stavebných uvedeného druhu, pri ktorom sa stavebninách nie je v priSom suchšieThis type of problem is that in the cross-section of building and panels, and the panels, distributed throughout the cross-section of building sites alternate which can cause cracks of panels, especially at their very disadvantageous, so that the task of manufacturing building it is not drier
Podstata vynálezuSUMMARY OF THE INVENTION
Túto úlohu splňuje spôsob výroby stavebnín, stavebných dielcov a panelov z cementu s vláknitým plnidlom podľa Hatschekového spôsobu, pri ktorom sa cement použije ako spojidlo a vlákna, ako vlákna z buničiny, plastikové vlákna a podobne, sa použijú ako výstuž, podľa vynálezu, ktorého podstatou je, že ôasť výsLužných vláken sa nahradí rozvi ákner.ými plastikovými zbytkamí a/alebo plastikovými odpadmi a/alebo rozviáknenými buničnými zbytkami a/alebo bun i čným i odpadla 1.This object is achieved by the Hatschek method of making building materials, components and cement panels with a fibrous filler in which the cement is used as a binder and fibers such as pulp fibers, plastic fibers and the like are used as reinforcement according to the invention. is that part of the reinforcing fibers is replaced by expanded plastic debris and / or plastic debris and / or expanded cell debris and / or cellular debris.
Týmto vyhotovením sa dosiahne to, že po prvé je možné spracovanie takého materiálu na Hatschekovon stroji, priSom spojenie cementom ako spoj idióm sa elektrickým povrchovým nábojom na základe použitia tohoto plastu zlepší tak, že podsitné pod valcovým sitom sa výrazne zníži.With this embodiment, it is achieved that, first, it is possible to process such a material on a Hatschekon machine, whereby the cement bonding as an idiom bond with the electric surface charge is improved by the use of this plastic so that the undercoat under the roller screen is significantly reduced.

Podľa známeho stavu techniky sa totiž zníženie podšitného š cementu dosiahne tým, že pridaním £1okulačného činidla dochádza k takzvanému tvoreniu vločiek, pričom vločky majú veľkosť. ktorá celkom zabráni prepadu pevnej látky valcovým s i ton.Indeed, according to the prior art, the reduction of the lining cement is achieved by the addition of a co-opacifier to the so-called flakes, the flakes having a size. which completely prevents the solids from falling through the cylindrical mesh.
Ha rozdiel od toho sa pri spôsobe podľa vynálezu pri výrobe stavebných hmôt spôsobí vytváranie vločiek plastom, čímIn contrast, in the method according to the invention, in the production of building materials, the formation of flocs by plastic is thereby caused
Λ vzniknú vločky s veľkosťou, ktorou sa podstatne vylúči to, že pevná látka môže otvormi valcového sita prepadnúť.Vločky flakes of a size are formed which substantially eliminate the possibility that the solid may fall through the holes of the cylindrical screen.
mm
Schopnosť cenentu zadržovať vodu je pri známom spôsobe výroby zhruba rovnaká ako pri spôsobe výroby podľa vynálezu. Spôsob výroby podľa vynálezu však má tú podstatnú výhodu, že rozloženie vlhkosti v priereze stavebného dielca, respektíve stavebnej hmoty, je rovnomerné, takže je zaistené, že už zmienenému nevýhodnému tvoreniu trhlín z dôvodu nerovnomerného rozloženia vlhkosti sa spôsobom podľa vynálezu zamedzí.The water retention capacity of the cenent in the known process is roughly the same as in the process according to the invention. However, the process of the invention has the significant advantage that the moisture distribution in the cross-section of the building component or the building material is uniform, so that it is ensured that the already mentioned disadvantageous crack formation due to uneven moisture distribution is avoided by the process of the invention.
Značná výhoda spôsobu podľa vynálezu totiž spoôíva v zlepšenom vytváraní kapilár čiže v zlepšenej poréznostl stavebnej hmoty, ktorej rovnomernosť lepšie ako v známych spôsoboch bráni vzniku trhlín.Indeed, a considerable advantage of the method according to the invention resides in the improved capillary formation, or in the improved porosity of the building material, whose uniformity better than in the known methods prevents cracks.
Spôsobom podľa vynálezu sa vzhľadom k rôznemu tvoreniu vločiek (veľké vločky oproti malým vločkám podľa známeho stavu techniky) síce vytvorí iná matrica, ktorá však má vyššie uvedené výhody týkajúce sa rovnomernosti rozloženia vlhkosti. Y. rovnomernému rozloženiu vlhkosti dôjde aj cez veľkosť vlečiek.The process according to the invention, due to the different flakes formation (large flakes over small flakes according to the prior art), forms a different matrix, but has the above-mentioned advantages regarding the uniformity of moisture distribution. Y. even moisture distribution will occur despite the plume size.
Táto matrica môže byť priamo spracovaná v Hatschekovom stroji, pričom ťažkosti z hľadiska výroby stavebných dielcov alebo panelov na formátovom a prsnom válci nevznikajú.This die can be directly processed in a Hatschek machine, with no difficulty in producing the components or panels on the size and breast rolls.
Podiel množstva plastov môže byt v rozsahu od 5 do 25 % * hmotnostných, pričom zvlášť výhodné je množstvo 15 % hmotnostných. Pomocou tohoto množstva použitých plastov sa vytvorí homogenná matrica. Voľba recyklovateľného plastu umožňuje vzhľadom k nákladom hospodárne použitie takého množstva. Takto vytriedený materiál môže byt* po vhodnej úprave spracovaný spôsobom podľa Hatscheka.The proportion of plastics may range from 5 to 25% by weight, with 15% being particularly preferred. A homogeneous matrix is formed with this amount of plastic used. The choice of recyclable plastic allows such an amount to be used economically in terms of cost. The sorted material can be treated by the Hatschek method after suitable treatment.
’ 'la vytvorenie potrebnej väzby slúži takzvaný rozdiel potenciálov Zeta. ktorý poskytuje jemné a malé vločky, takže e na prívod cementu do valcového sita a na zabránenie jeho prepadu otvormi valcového sita je potrebné prídavné vločkovanie, pri ktorom sú taktiež jednotlivé vločky podstatne väčšie ako vločky vytvárané rôznym potenciálom Zeta.'' And the creation of the necessary bond serves the so-called Zeta potential difference. This provides an additional flocculation in which the individual flocs are also considerably larger than those produced by the different Zeta potentials.
Potenciál Zeta je Leda elektrickým povrchovým nábojom, ktorý spôsobuje tesnejšiu väzbu medzi cementom a vláknami. Pritom sa jedná o rozdiel potenciálov, ktorý existuje buď medzí plusovou a mínusovou hodnotou alebo medzi dvoma plusovými a/alebo dvoma mínusovými hodnotami.The potential of Zeta is Leda's electrical surface charge, which causes a closer bond between cement and fibers. This is a potential difference that exists either between the plus and minus values or between two plus and / or two minus values.
