Definitions

  • the present invention generally relates to the technical field of producing mineral fiber-insulating plates.
  • Mineral fibers generally comprise fibers such as rockwool fibers, glass fibers, etc. More precisely, the present invention relates to a novel technique of producing a mineral fiber-insulating web from which mineral fiber-insulating plates are cut.
  • the mineral fiber-insulating plates produced from the mineral fiber-insulating web produced in accordance with the present invention exhibit advantageous characteristics as to mechanical performance, such as modulus of elasticity and strength, low weight and good thermal-insulating property.
  • Mineral fiber-insulating webs are normally hitherto produced as homogeneous webs, i.e. webs in which the mineral fibers of which the mineral fiber-insulating web is composed, are generally orientated in a single predominant orientation which is mostly determined by the orientation of the production line on which the mineral fiber-insulating web is produced and transmitted during the process of producing the mineral fiber-insulating web.
  • the product made from a homogeneous mineral fiber-insulating web exhibits characteristics which are determined by the integrity of the mineral fiber-insulating web and which are predominantly determined by the binding of the mineral fibers within the mineral fiber-insulating plate produced from the mineral fiber-insulating web, and further predominantly determined by the area weight and density of the mineral fibers of the mineral fiber-insulating plate.
  • a method of producing an insulating mineral fiber plate composed of interconnected rod-shaped mineral fiber elements includes cutting a continuous mineral fiber web in the longitudinal direction thereof in order to form lamellae, cutting the lamellae into desired lengths, turning the lamellae 90° about the longitudinal axis and bonding the lamellae together for forming the plate.
  • the method also includes a step of curing the continuous mineral fiber web, or alternatively the plate composed of the individual lengths of lamellae bonded together for the formation of the plate.
  • a method of producing a fibrous sheet structure including filaments or fibers of a polymeric material such as polyethylene trephtalate or polyhexamethyleaditamide is known.
  • the method includes producing the polymeric material filaments or fibers by means of a carting machine from a supply of filaments or fibers constituted by a porous resilient bat of filaments or fibers, collecting the polymeric material filaments or fibers on a belt for the formation of a continuous web of polymeric material filaments or fibers, compressing the web, cutting the web into a series of parallel fiber strips including polymeric material filaments or fibers and turning the fiber strips 90° about the longitudinal axis and adjoining the strips together as the strips are caused to effect unification solely through the release of a compression effect which has been applied to the strips during the process of turning the strips.
  • the web produced in accordance with the technique described in the above US patent is suitable for manufacturing fabrics such as carpets, blankets, bed spreads, bathrobes etc.
  • An object of the present invention is to provide a novel method of producing a mineral fiber-insulating web from which mineral fiber-insulating plates may be cut which method renders it possible in an online production plant to produce mineral fiber-insulating plates which are of a composite and complex structure providing distinct advantages as compared to the prior art homogeneous single direction orientated mineral fiber-containing plates.
  • a particular advantage of the present invention relates to the novel mineral fiber-insulating plate according to the present invention and produced in accordance with the method according to the present invention which as compared to prior art mineral fiber-insulating plates contains less mineral fibers and is consequently less costly than the prior art mineral fiber-insulating plates, still exhibiting advantages as compared to the prior art mineral fiber-insulating plates relating to mechanical performance and thermal-insulating properties.
  • a further advantage of the present invention relates to the fact that the amount of material wasted by producing mineral fiber-insulating plates in accordance with the method according to the present invention is basically non-existing, or at least reduced to a very low percentage, such as the percentage of 0-2% of the amount of material used for producing the mineral fiber-insulating plate.
  • a particular feature of the present invention relates to the fact that the novel mineral fiber-insulating plate according to the present invention and produced in accordance with the method according to the present invention is produceable from less mineral fibers or less material as compared to the prior art mineral fiber-insulating plate still providing the same properties as the prior art mineral fiber-insulating plate regarding mechanical performance and thermal-insulating properties, thus, providing a more lightweight and more compact mineral fiber-insulating plate product as compared to the prior art mineral fiber-insulating plate product reducing transport, storage and handling costs.
  • the third non-woven mineral fiber web which is adjoined to the second mineral fiber web in step f) may constitute a separate mineral fiber web.
  • the first and the third mineral fiber webs may be produced by separate production lines which are joined together in step f).
  • the third non-woven mineral fiber web is produced by separating a surface segment layer of the first mineral fiber web therefrom and by compacting the surface segment layer for producing the third mineral fiber web.
  • the method according to the present invention preferably further comprises the additional step similar to step g) of producing a fifth non-woven mineral fiber web similar to the third mineral fiber web, and the step of adjoining in step h) the fifth mineral fiber web to the second mineral fiber web in facial contact therewith and so as to sandwich the second mineral fiber web between the third and fifth mineral fiber web in the fourth mineral fiber web.
  • the first mineral fiber web from the basic non-woven mineral fiber web by arranging the basic mineral fiber web in overlapping layers, the general orientation of the mineral fibers of the basic non-woven mineral fiber web is shifted from the longitudinal direction of the basic mineral fiber web to the transversal direction of the first non-woven mineral fiber web.
  • the basic non-woven mineral fiber web is preferably arranged in overlapping relation generally in the second transversal direction.
  • the first and second non-woven mineral fiber webs are preferably exposed to compacting and compression in order to provide more compact and more homogeneous mineral fiber webs.
  • the compacting and compression may include heigt compression, longitudinal compression, transversal compression and combinations thereof.
  • the method according to the present invention preferably further comprises the additional step of height-compressing the first non-woven mineral fiber web produced in step a) and preferably produced from the basic non-woven mineral fiber web as described above.
  • the method according to the present invention may comprise the additional step of longitudinally compressing the first non-woven mineral fiber web produced in step a) and additionally or alternatively the additional step of longitudinally compressing the second non-woven mineral fiber web produced in step e).
  • the mineral fiber web exposed to the longitudinal compression is made more homogeneous, resulting In an overall improvement of the mechanical performance and, in most instances, the thermal-insulating property of the longitudinally compressed mineral fiber web as compared to a non-longitudinally compressed mineral fiber web.
  • the mineral fiber-insulating plates produced in accordance with the method according to the present invention exhibit surprisingly improved mechanical properties and mechanical performance, provided the second non-woven mineral fiber web produced in step e) is exposed to transversal compression, producing a homogenization of the mineral fiber structure of the second non-woven mineral fiber web.
  • the transversal compression of the second non-woven mineral fiber web results in a remarkable improvement of the mechanical properties and performance of the final mineral fiber-insulating plates produced from the second non-woven mineral fiber web, which improvement is believed to originate from a mechanical repositioning of the mineral fibers of the second non-woven mineral fiber web, as the second non-woven mineral fiber web is exposed to the transversal compression, by which repositioning the mineral fibers of the second non-woven mineral fiber web are evenly distributed throughout the uncured mineral fiber web.
  • the method according to the present invention may further preferably and advantageously comprise the step of applying a foil to a side surface of both side surfaces of the first non-woven mineral fiber web and/or applying a foil to a side surface or both side surfaces of the second non-woven mineral fiber web.
  • the foil may be a foil of a plastics material, such as a continuous foil, a woven or non-woven mesh, or alternatively a foil of a non-plastics material, such as a paper or cloth material.
  • the mineral fiber-insulating web produced in accordance with the method according to the present invention may, as discussed above, be provided with two oppositely arranged mineral fiber webs sandwiching a central body of the composite mineral fiber-insulating web. Provided the mineral fiber-insulating web is produced as a three-layer assembly, one or both outer side surfaces may be provided with similar or identical surface coverings.
  • the method according to the present invention may further comprise the additional step of compressing the fourth composite mineral fiber web prior to introducing the fourth composite mineral fiber web into the curing oven.
  • the compressing of the fourth composite mineral fiber web may comprise height compression, longitudinal compression and/or transversal compression.
  • the step i) of curing the first curable bonding agent and optionally the second and third curable bonding agents as well may, dependent on the nature of the curable bonding agent or bonding agents, be carried out in numerous diffent ways, e.g. by simply exposing the curable bonding agent or bonding agents to a curing gas or a curing atmosphere, such as the atmosphere, by exposing the curable bonding agent or bonding agents to radiation, such as UV radiation or IR radiation.
  • the process of curing the curable bonding agent or bonding agents includes the step of introducing the mineral fiber web to be cured into a curing oven. Consequently, the curing process is performed by means of a curing oven.
  • Further alternative curing appliances may comprise IR radiators, microwave radiators, etc.
  • plate segments are preferably cut by cutting the cured fourth composite mineral fiber web into plate segment in a separate production step.
  • the plant according to the present invention may additionally advantageously comprise any of the above features of the method according to the present invention.
  • a structural panel which structural panel is produced from lamellae including mineral fibers and being linked together by means of reinforcing strips which are adhered to the lamellae by means of adhesives which are cured in a separate or further curing process.
  • two separate heat curing processes are utilized, a first heat curing process being used for curing the bonding agent bonding the mineral fibers of an integral mineral fiber web together from which integral and bonded mineral fiber web the lamellae are cut, and a second heat curing process in which the reinforcing elements are bonded to the previously cured mineral fiber containing lamellae.
  • the mineral fiber-insulating plate according to the present invention preferably comprises opposite surface layers of similar structure sandwiching the central body in the integral structure of the mineral fiber-insulating plate.
  • a first step of producing a mineral fiber-insulating web involves the formation of mineral fibers from a mineral fiber forming melt which is produced in a furnace 30 and which is supplied from a spout 32 of the furnace 30 to a total of four rapidly rotating spinning-wheels 34 to which the mineral fiber forming melt is supplied as a mineral fiber forming melt stream 36.
  • a cooling gas stream is simultaneously supplied to the rapidly rotating spinning-wheels 34 in the axial direction thereof causing the formation of individual mineral fibers which are expelled or sprayed from the rapidly rotating spinning-wheels 34 as indicated by the reference numeral 38.
  • the mineral fiber spray 38 is collected on a continuously operated first conveyer belt 42 forming a primary mineral fiber-insulating web 40.
  • a heat-curable bonding agent is also added to the primary mineral fiber-insulating web 40 either directly to the primary mineral fiber-insulating web 40 or at the stage of expelling the mineral fibers from the spinning-wheels 34, i.e. at the stage of forming the individual mineral fibers.
  • the first conveyer belt 42 is, as is evident from Fig. 1, composed of two conveyer belt sections. A first conveyer belt section which is sloping relative to the horizontal direction and relative to a second substantially horizontal conveyer belt section.
  • the first section constitutes a collector section
  • the second section constitutes a transport section by means of which the primary mineral fiber-insulating web 40 is transferred to a second and a third continuously operated conveyer belt designated the reference numeral 44 and 46, respectively, which are operated in synchronism with the first conveyer belt 42 sandwiching the primary mineral fiber-insulating web 40 between two adjacent surfaces of the second and third conveyer belts 44 and 46, respectively.
  • the second and third conveyer belts 44 and 46 communicate with a fourth conveyer belt 48 which constitutes a collector conveyer belt on which a secondary mineral fiber-insulating web 50 is collected as the second and third conveyer belts 44 and 46, respectively, are swung across the upper surface of the fourth conveyer belt 48 in the transversal direction relative to the fourth conveyer belt 48.
  • the secondary mineral fiber-insulating web 50 is consequently produced by arranging the primary mineral fiber-insulating web 40 in overlapping relation generally in the transversal direction of the fourth conveyer belt 48.
  • the secondary mineral fiber-insulating web 50 By producing the secondary mineral fiber-insulating web 50 from the primary mineral fiber-insulating web 40 as disclosed in Fig. 1, a more homogeneous secondary mineral fiber-insulating web 50 is produced as compared to the less homogeneous primary mineral fiber-insulating web 40.
  • the overall orientation of the mineral fibers of the primary mineral fiber-insulating web 40 is parallel with the longitudinal direction of the web 40 and the direction of transportation of the first conveyer belt 42.
