SK95195A3 - Fabrication of building materials and elements as well as building panels from fibrous cement - Google Patents

Abstract

The boards are produced using the Hatschele process and the fibres are, e.g. cellular material or plastic. Some of the reinforcing fibres are replaced by plastic residue and/or waste. The above components pref. make up 5-25, esp. 15-25 wt.% of the total matrix.

Description

BACKGROUND 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

The invention relates to parts and panels 2 of the Haschschek method, joints and fibers as well as the like as reinforcement.

BACKGROUND OF THE INVENTION

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.

This cracking feature of the invention is to provide a method of panels and panels above avoiding cracking.

This 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

SUMMARY OF THE INVENTION

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.

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.

F

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.

In contrast, in the method according to the invention, in the production of building materials, the formation of flocs by plastic is thereby caused

Vločky flakes of a size are formed which substantially eliminate the possibility that the solid may fall through the holes of the cylindrical screen.

m

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.

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.

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.

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.

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.

'' 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.

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.

Claims (4)

PATENT CLAIMS 1. Method of building construction. Fiber filler cementitious components and panels according to the Hatschek method in which the cement is used as a binder and fibers such as pulp fibers, plastic fibers and the like are used as reinforcement, characterized in that a portion of the reinforcing fibers is replaced by rolled plastic fibers. residues and / or plastic waste and / or pulled with cellulosic residues and / or cellulosic waste. Method according to claim 1, characterized in that the proportion of said materials in the entire matrix is in the range of from 5 to 25% by weight. Method according to claim 1, characterized in that the proportion of said materials in the entire matrix is 15% by weight. Method according to one of Claims 1 to 3, characterized in that. It is believed that cement and fibers form flakes that are substantially heavier than flakes that arise from less zeta potential differences between the individual substances.
