The unit principally refers to an operator consistently applying introductory-level knowledge and workplace procedures to mechanical wet lay-up techniques, with operator control of the lay-up process. This unit applies to an individual working alone or as part of a team.

This unit describes the applied skills and knowledge required to lay-up polymer-matrix laminates using a manual chopper gun. Supersedes and is equivalent to PMBPROD280 Operate resin-glass depositor equipment. Elements and Performance Criteria changed. Get in touch with us today for more information or call us at (386) 758-0057.Release 1. Over the many years that we’ve been providing our services, we’ve garnered a stellar reputation for excellence in custom fiberglass work, working with some of the largest organizations in the world. We’re a trusted name in fiberglass surface coating, FRP Pipe Repair, fiberglass tank repair, fiberglass surface coating, and installation service provider based in Lake City, FL. If you’ve decided to purchase FRP tanks for your organization, it’s highly recommended that you let profess ionals handle all the installation procedures to prevent any problems from occurring. Without this extra layer of protection, fiberglass tanks suffer from the same UV damage as polyethylene tanks do.
A gel or paint coat is the final layer applied to the tank to protect it from ultraviolet rays.Accessories and fittings, such as manways, and cleanouts, are added once the tank is glassed and assembled.Final fiberglass layers are applied over the exterior so the fasteners and the rest of the tank are indistinguishable.Finished bottoms and tops are attached to a tank’s sidewall with fasteners.The sidewalls, bottoms, and tops of the tanks are all constructed separately.A hardener, along with liquid resin, is simultaneously mixed with the fiberglass as it passes through and leaves the chopper gun. A chopper gun is used to cut strands of fiberglass into smaller pieces.Here’s what the chopper gun method involves: The chopper gun method utilizes metal molds to create the top, bottom, and sides of a fiberglass tank. Once the tank is ready, openings are cut for fixtures and attachments.įiberglass Tank Construction: Chopper Gun Method.All the remaining layers of the fiberglass are added using a chopper gun.In order to prevent the open end of the tank from falling in, a steel ring is placed near the opening.Once the resin and mats dry, the tank mold can be removed.As the mold rotates, it pulls these strands and wraps them over the tank.Individual strands of the glass are applied to the mat.Rollers are used to allow air bubbles to escape the fiberglass mat.Here are all the steps involved in this method: Hardeners and resin aren’t mixed with the fiberglass because the resin is only added to the bottom of each layer. The filament winding method utilizes a spool to wind a layer of glass around a rotating tank mold. Fiberglass Tank Construction: Filament Winding Method We’ve prepared this comprehensive guide on how fiberglass tanks are constructed to help you do just that. By gaining some insight into how FRP tanks are constructed, you’ll gain an understanding of the benefits they provide. They are made using one of two methods: the filament winding method and the chopper gun method.
FRP tanks are made of plastic that is reinforced with fiberglass, not unlike the way rebar is reinforced with concrete. What most people call fiberglass tanks are actually known as fiberglass reinforced plastic (FRP) tanks.
