Expression "to glue fiber glass fabric" often it is used in value – to make any product of fiber glass fabric and polymeric pitch (most often epoxy). Fiber glass fabric in combination with pitch is such plastic material that it is nearly possible to make of it anything: the boat, amusing mask, "weather-cloths" for the car, armor of the medieval knight and so forth. At respect for technology the product turns out strong and durable.
It is required to you
- – constructional fiber glass fabric;
- – epoxy resin with hardener;
- – polyurethane foam;
- – universal construction putty;
- – palettes;
- – emery cloth;
- – paraffin or stearin;
- – brush with rigid bristle;
- – tools for cutting (stationery knife, the fret saw, shaving edges and so forth).
Instruction
1. Production of any product from fibreglass is carried out in two stages: at first the form (matrix) for it, then – product becomes. Production to matritsyizgotovta framework (pig) for matrix. Its form and the sizes have to correspond to product for which it intends. Depending on type of product various material can be used: tree, wire, plastic. If it is supposed to make product of irregular shape, as surface layer of matrix it is convenient to use polyurethane foam. In this case, determining the framework sizes, you recognize that over it the layer of polyurethane foam 3-4 cm thick will be located.
2. Apply on pig polyurethane foam with the layer having thickness of 3-4 cm. It is desirable to apply foam not with some, but several layers. After final hardening give to matrix the form of product. For processing of surface of polyurethane foam use stationery knife, shaving edges, abrasive paper, the fret saw, the Bulgarian.
3. Apply on matrix surface suitable structure for concealment of time and alignment of surface, for example, construction and universal putty. After drying grind it emery cloth. Repeat this operation so many time how many it will be required in order that the surface of matrix became smooth.
4. Cover matrix with one of the dividing materials serving for prevention of sticking of product to form. It can be paraffin, stearin, parquet polish, etc. After drawing and drying of structure polish surface with piece of fabric.
5. Production epoxy resin with hardener in necessary proportion also apply to izdeliyasmeshayta it with the palette thin layer on matrix. Give time to pitch to harden then put the second layer.
6. Lay on pitch fiber glass fabric, prikatayta its stitching roller or press and condense with brush with rough bristle. Achieve that fiber glass fabric has become impregnated completely, and – very important requirement – all air from under fabric was removed. Otherwise it can lead to local stratifications and buckling. If on difficult surface the fiber glass fabric fold was formed, cut off it knife or scissors and densely press cut edges to surface.
7. Repeat the procedure pro-dabs pitch and fiber glass fabric stickers several times – depending on what durability is required from product. Are usually limited to three-five layers of fiber glass fabric. After final polymerization of pitch take product from form. Now it is possible to paint and varnish it.
