Po??czenie warstw jest te? mo?liwe bez tych komponentów, gdy? warstwa polipropylenu poddana temperaturze uplastycznia si? i ??czy z p?yt? wewn?trzn?. Z polskiego prawa ochronnego, nr Ru-65265, znana jest wzmocniona sklejka, zbudowana z trzech warstw forniru, w której pomi?dzy warstwami zewn?trznymi w uk?adzie wzd?u? w?ókien forniru jest wzmocniona siatkami z w?ókna szklanego, a pomi?dzy siatkami z w?ókna szklanego znajduje si? warstwa ?rodkowa forniru w uk?adzie w poprzek w?ókien. Sklejka przeznaczona jest do stosowania w meblarstwie i budownictwie. Z polskiego prawa ochronnego, nr Ru-68850, znana jest p?yta warstwowa, w której wewn?trzna p?yta wiórowa jest oklejona warstwami ?uszczu (forniru), za pomoc? kleju fenolowo-formaldehydowego lub mocznikowo-formaldehydowego. Istota p?yty warstwowej z siatk? wzmacniaj?c?, o co najmniej jedenastu warstwach forniru, wed?ug wzoru u?ytkowego, polega na tym, ?e do warstw forniru, klejonych przy u?yciu kleju fenolowo--formaldehydowego lub mocznikowo-formaldehydowego, wklejone s? warstwy siatki wzmacniaj?cej z w?ókna szklanego, znajduj?ce si? pomi?dzy drug? i trzeci? oraz trzeci? i czwart? warstw? forniru (?uszczu), licz?c od zewn?trznych (skrajnych) warstw p?yty. Pomi?dzy warstwami czwartymi znajduje si? wk?ad sklejkowy, zawieraj?cy co najmniej trzy warstwy forniru (?uszczu) o budowie krzy?owej. Przedstawiona p?yta warstwowa ma w?a?ciwo?ci fizyczne zbli?one do sklejki, natomiast jej w?a?ciwo?ci mechaniczne, dzi?ki zastosowaniu siatki wzmacniaj?cej uleg?y podwy?szeniu w stosunku do sklejki klejonej tradycyjnie (metod? krzy?ow?). P?yta warstwowa - sklejka z wklejon? siatk? wzmacniaj?c? wed?ug wzoru u?ytkowego zosta?a pokazana na ilustracji - Fig. 1, przedstawiaj?cej p?yt? w przekroju. P?yta warstwowa zbudowana jest z 11 sklejonych ze sob? warstw forniru. Pomi?dzy warstwami drug? 1 i trzeci? 2 oraz trzeci? 2 i czwart? 3 forniru (?uszczu), licz?c od zewn?trznych (skrajnych) warstw p?yty-sklejki, ma wzmocnienie z siatek z w?ókna szklanego 4. Pomi?dzy warstwami czwartymi 3 znajduje si? wk?ad sklejkowy 5, zawieraj?cy trzy warstwy forniru (?uszczu) o budowie krzy?owej. Liczba siatek wzmacniaj?cych jak i forniru zale?na jest od docelowej grubo?ci p?yty i wymaganej wytrzyma?o?ci. Dodatkowo tak? p?yt? mo?na uszlachetni? poprzez: - naklejenie na prasie na szerokie p?aszczyzny p?yty: filmu fenolowego, melaminowego lub papieru do malowania, - przyklejenie na szerokie p?aszczyzny p?yty arkuszy z tworzywa sztucznego np. polipropylenowego, - pokrywanie powierzchni p?yty olejami mineralnymi, - lakierowanie, - malowanie. PL PL PL PL PL Description of the pattern The subject of the utility pattern is a sandwich panel with a mesh. strengthening, applicable in areas requiring increased strength, mainly in means of transport, as well as in construction and everywhere where they are needed increased strength parameters with a specific board thickness. They are known? various solutions of sandwich panels for various purposes and various types of internal filling material and various external coating materials. From the Polish patent description, Pat. 185011, a cladding board is known which consists of alternating between resin and stone grit, and its essence? is that the first? layers? outside is a polyester ortaphthalic gelcoat. Acrylic resin. From the Polish protection law no. Rz-17562, granted in the form of a decorative pattern, a sandwich panel is known, the external layers of which are made of a profiled sheet, while filling - polyurethane foam. Another Polish protection law, no. Rp-330, granted in the industrial design, describes a sandwich panel in which the external layers are flat sheets and the internal filling is polystyrene. The well-known sandwich panels intended for formwork are intended to be generally post? wooden plywood covered with foil on both sides? phenolic. A sandwich panel is known from the Polish protection law No. Ru-63881, granted as a utility model. Internal board - plywood, consisting of from stuck together? layers of wood, is covered on the top and bottom with a layer of wood. polypropylene. Polypropylene layers can was? permanently connected to the board inside for help? thermoplastic phenolic film or glue. The combination of layers is also possible without these components, because? the polypropylene layer becomes plastic when subjected to temperature and connects to CDs? inside. From the Polish protection law, No. Ru-65265, a reinforced plywood is known, made of three layers of veneer, in which, between the outer layers in a longitudinal pattern, The veneer fibers are reinforced with glass fiber meshes, and between the glass fiber meshes there is a fiberglass mesh. middle ply of veneer in a pattern across the grain. Plywood is intended for use in furniture and construction. From the Polish protection law, No. Ru-68850, a sandwich panel is known, in which the inner particle board is covered with layers of grease (veneer) using phenol-formaldehyde or urea-formaldehyde glue. The essence of a sandwich panel with a mesh reinforcement, with at least eleven veneer layers, according to the utility pattern, is that the veneer layers glued with phenol-formaldehyde or urea-formaldehyde glue are glued with of the fiberglass reinforcing mesh layer between the other and the third? and the third? and fourth? layers? veneer (fat), counting from the outer (outermost) layers of the board. Between the fourth layers there is a plywood block, containing at least three layers of cross-grain veneer (fat). The presented sandwich panel has physical properties similar to plywood, while its mechanical properties, thanks to the use of a reinforcing mesh, have been improved compared to glued plywood. traditionally (cross method). Sandwich panel - plywood with glued in net strengthening according to the utility pattern was shown in the illustration - Fig. 1, showing the board in section. The sandwich panel is made of 11 panels glued together. veneer layers. Between the second layers 1 and the third? 2 and the third? 2 and 4? 3 of the veneer (fat), counting from the outer (extreme) layers of the plywood board, has a reinforcement of fiberglass mesh. Plywood insert 5, comprising three layers of cross-grained veneer (grease). The number of reinforcing meshes and veneers depends on the target board thickness and the required strength. Additionally, yes? CD can you ennoble? by: - sticking on the press on wide surfaces of the board: phenolic film, melamine film or painting paper, - gluing plastic sheets, e.g. polypropylene, on wide surfaces of the board, - coating the board surface with mineral oils , - varnishing, - painting.
