A Boiler Constructed Using A Composite Material Full description

Sal Scope The invention relates to a boiler made of a polymeric matrix composite material -water heater (Sle in particular; in a heater 0 for use polymeric matrix composite material Technical background Long before now; the applicant was increasingly interested Using polymeric base materials ana for ela purposes to contain synthetic components as suitable materials for the manufacture of components heated either by gas or electricity.This interest stems from a number of advantages possessed by these materials used so far. Compared to metal materials traditionally used in metal boilers, the first defect of metal boilers is Law, which occurs on the inner surfaces, electrolytic corrosion, due to the phenomenon of electrolytic corrosion, Ve. For the aforementioned boilers, to nullify the molten current, appropriate anodes or internal claddings, the use of sacrificial sacrificial casings. Production using chemicals to prepare metal surfaces vo the short working life of metal boilers Another drawback is also from Liu, traditional operating life. The designs proposed so far tend to manufacture boilers of cdl gall materials and when choosing water heaters ; in general; to prefer materials with synthetic material boilers v structural strengthening properties Special mechanical and special forms of structural strengthening He is studying the Italian International Patent Application No. 97/001876 in accordance with the Patent Cooperation Treaty; For example; The use of alloy polymeric materials modified with other industrial polymers, as these aforementioned alloy polymeric materials, which return positive mechanical stress resistance, have the advantages of resistance to positive mechanical stress 0 reinforcing agents, as well as to add reinforcing agents, and it is proposed to apply for the international European patent No. 097477/98 in accordance with the Patent Cooperation Treaty; A method to achieve significant mechanical resistance advantages for a boiler for water heaters made of synthetic material with structural reforcing ribs 1 In both of the inventions referred to, the used boiler is made by bonding two components and these solutions require; adhesives or by using Welding adhesives Lea two or more that are structurally weak Adequate settings to ensure material working conditions so that they do not occur in special cases; Within the Las which pressure potentially dangerous situations for the user due to the pressure the water is stored in the said boiler. of a synthetic polymeric material in the form of a single body with no structurally weak design possible. A second objective of the boiler in question in this invention is to have similar production costs but to be made of metal. Other objectives arise from the ease with which components can be recycled and an operating life of at least 01 years. The aforementioned objectives are achieved with the least possible impact on the surroundings during the production phase and with very low energy consumption during the production phase and when the heater is

¢ The water boiler is in use; Compared to other water heaters available in the market. The boiler under study is distinguished in the present invention; for private use; In a heater (le) equipped with a heating element, preferably, but not exclusively, to be 0 electrical and of the type made entirely of a basic polymeric composite material that includes a first layer made of plastic material It has a property that makes it suitable for contact with water for sanitary purposes, and a second layer made of a composite material consisting of Gl high-tensile tensile fibers. Elastic 'elastomeric matrix material Ve' The second layer consists of a multitude of filaments or synthetic strips wrapped around the first layer, where the said filaments or strips are covered with resins that accumulate through reticulation. Or Hfusion, and the aforementioned second layer is made in the form of a single body and is designed to create structural resistance to the boiler. end of its operating life. Brief Explanation of Drawings These and other features are best shown in the following description of the embodiment of Jade ‎iad - © The invention is provided without limitation with the accompanying drawings; Where: Figure 1: shows a boiler fitted inside an electric water heater; Figure 1 : Shown schematically and without scale; Section of the boiler. DESCRIPTION All For details, refer to Figure 10; the number 1 is used to indicate a water heater to which a boiler is supplied. Yo Inside the boiler ¥ is a heating element; electric type. YYye

In the form oY the number denotes ; To a first layer that is in direct contact with hot water or water that should be heated, and the number © indicates the At layer outside the first layer. and make the first layer; of a thermoplastic matrix consisting of a chomopolymeric 0017015012 polyolefin resin ° copolymer “metallocenic copolymeric” or 0127-based resins or PPE/PPO-based resins or even a mixture of materials other recombinant polymeric materials or such materials made recombinant; Either semi-crystalline materials or amorphous materials may make the first layer; also of an elastomeric matrix material consisting of PB or PIB based resins or even mixtures with other copolymers or such - materials made recombinants; Either semi-crystalline materials or amorphous materials. The two layers can be separated; and © Lal from each other, provided that each of them is in the form of a single body. And wrap one layer + of the water heater 1 which contains the boiler? around the outer surface of said boiler and designed to provide said Ja yell thermal insulation; ve layer 1 can be separated from the outer surface of the second layer 0 A first feature of the boiler in question of the present invention is that the second layer designed to supply the necessary structural resistance to said boiler ensures; at least; Bursting value when hot; Not less than Ye bar at 0 lm (Celsius C) and the number of mechanical fatigue cycles ranging from 1 bar to +bar in excess of > 7000 required by special safety standards. A second advantage arises from the fact that the industrial cost of the boiler of the present invention is substantially the same as the industrial cost of a boiler of the same capacity but made entirely of metal.An additional advantage arises from the ease of turning the individual components when grinding or sale using the boiler unit. The complete interior boiler unit is under investigation in this invention.

+ An additional advantage also arises from less environmental impact during the production phase and energy consumption both during the production phase and when said boiler is in use; Which is Tan SUE compared to other products on the market today. Las additional advantages are the natural light weight of the unit and the absence of any element 0 designed to resist JSG on the inner surface of the boiler. of ual The boiler of the subject of the present invention has the additional advantage (A Baia) in that its heat production levels are; In addition to its mechanical performance levels; Not less than these levels for metal boilers. another unexplained embodiment is imagined; use of a layer consisting of a plurality of filaments or 0 strips of synthetic material covered with resins accumulated by crosslinking or fusion outside the boiler made of the said polymeric material; to use; In particular; In a heater (Ble) fitted with a heating element preferably, but not exclusively, electrical and characterized by the fact Abdel in being composed of two or more elements held together by welding, adhesion or other method. Vo and said cover is applied to Said assembly elements when fully assembled Said layer and the boiler produced after complete assembly of the two or more said elements shall be fixed with such a manner as to permit their total separation In this description I specifically refer to a water heater provided within the boiler of the present invention However said boiler may be used They are also usefully suited to +> application areas other than water heaters.
