The quality of glass steel grille plate first depends on the quality of raw materials, to the quality of the products cover glass steel grille on the compressive strength, tensile strength, corrosion resistance can reach the industry standard, it must be consistent and stability requirements of quality raw materials. The use of high quality materials to some extent can improve the quality of products, grades, reputation and production efficiency, performance and price ratio, the relative cost reduction.
At present, compared with the imported materials, the domestic glass fiber reinforced plastic grid cover plate has reached the same level both in product quality and product grade. In China, the unsaturated polyester resin production of many manufacturers, the output of more than 1 million 500 thousand tons, basically through the ISO9000 series certification; filler, pigment, catalyst, curing agent, release agent (internal and external), defoaming agent, anti ultraviolet absorbent, inhibitor and other additives quality, varieties and grades are to be to further improve the.
China's glass fiber reinforced plastic grid cover industry should be in its raw materials and auxiliary production, processing, research and development efforts. At present, the industry of inferior glass steel grille plate industry in China of raw materials and crudely made is also more common phenomenon, the adverse impact caused has seriously affected the FRP grating image, establish a good image is of great significance to promote the development of glass steel grille plate grille pultrusion industry and the whole glass steel industry.
In addition the cover glass steel grille pultrusion internal quality and mechanical properties of existing problems: the technical data of measured data and product data provide larger problems; flame retardant properties, can not meet the increasing requirements of flame retardant, especially construction; corrosion resistance, easy aging fade, anti UV absorbers lack etc.. Our country lacks the standard and test standard. Through the above analysis, is closely related to quality and cover glass steel raw material producers, suppliers, and is in the process of production must Seiko secret agents, every step, every step must be strictly in accordance with the process of operation, in order to make the product quality in the industry have reached the standard step by step, in a hand.
