Exploration Of Glass Fiber Reinforced Corrosion Resistant Resin Flooring Technology

- Jul 25, 2017 -

Selection of raw materials for GFRP

Corrosion-resistant resin flooring reinforced matrix materials, generally selected in alkali or no alkali glass gfrp cloth without twist. Glass cloth corrosion Resistance comparison table L two kinds.

Second, the choice of resin

From corrosion resistance, xylene resin, vinyl resin, epoxy resin and unsaturated polyester resin have good acid and alkaline, especially in the more suitable acidic medium, unsaturated polyester resin resistance to acid slightly worse, but good alkali resistance. From the high temperature resistance, epoxy resin or phenolic resin, unsaturated polyester resin is good. From adhesion to see, phenolic type epoxy resin, epoxy resin highest second. From curing shrinkage to see the lowest xylene resin, epoxy resin is the highest second smallest and unsaturated polyester resin. From the appearance of fluidity, unsaturated polyester resin is epoxy resin is good. Combined with these analyses, we adopt the production of vinyl resins on the floor surface of the steel layer with xylene resin and glass fiber reinforced epoxy or phenolic epoxy resin price bottom coating. Third, packaging

According to the corrosion characteristics of the floor, we choose packaging, in the packaging of corrosion resistance, wear resistance and shrinkage, and combined with other factors, including diabase powder, cast stone powder, porcelain powder, the focus of the use of the powder is more.

Stress analysis and structural design of corrosion resistant floor

Corrosion wear-resistant floor hardened cement base shop covered with glass cloth, impregnated resin, cured resin has a certain heat shrinkage, the use of floors in the expansion and contraction of the phenomenon. These factors result in shear stress between the resin glass fiber reinforced layer and the cement base interface. If the adhesion of the interface is less than the shear stress, the resin glass reinforced layer and the cement base or cracking. Conversely, if the cement base strength is less than the shear force, the cement base of the boom. Therefore, we require the cohesion of the interface and the strength of the base to be greater than the shear stress. In fact, the strength of cement base is generally higher than shearing force, our main consideration is to ensure that the interfacial bonding force is greater than the interfacial shear force. Based on this, we usually choose the interfacial bonding agent (bottom coating) of epoxy resin or phenolic type epoxy resins with higher cohesion. Because the epoxy primer coating also fills the cement base surface micro holes and cracks, the formation of a homogeneous layer of resin layer, to prevent the media on the basis of erosion.
