FRP cover the production environment and the economy in order to protect the quality fiberglass contrast cover can use compliance requirements, in addition to open the selection of raw materials and a balanced ratio, producing a part of the background is also very close tight. Fiberglass cover production background should pay attention to several aspects: First, the satisfactory background. Background covering two points, one is natural background, an artificial background. 1. Natural background, temperature to maintain a fairly firm stable temperature, is in general between 21 and 28 ℃. Wetting degree should have a fairly appropriate background, preferably between 40 and 60, and no not more than 65. 2. artificial background, there must be a source of clean gas production plant. Secondly, the quality fiberglass material. At the time the selection of manufacturing FRP material products (such as glass, steel plate) to pay attention to the selection of high-quality raw materials and auxiliary. Ultimately, there must be reasonable manufacturing schedule. Products of the time by a special chemical properties of raw materials and accessories to vote, so be on the basis of the nature of the raw materials and accessories to accommodate the schedule well made. Period of time to invest FRP grating economic comparison with other products fiberglass cover start than pig iron, steel grille large, but because without protection spending, long life to survive, so the overall economic efficiency superior to other materials, according to the beginning stage estimates, in the use of things such as functional status, fiberglass cover and other products for the price of dwarf: iron: steel plate (grill factory order): Steel plate (homemade): steel plate: FRP cover = 1: 1.1: 1.15: 1.4: 0.5. Satisfied all the requirements of the production, the ability to guarantee the quality of the finished fiberglass cover firmly stability. Economic capacity corresponding to cover increased, and general metal, wood dwarf, high cost, the use of the survival of life is long.
