Get 100 weight portion SWANCOR901 type vinyl ester resins or other bisphenol types, metaphenylene and p-phenyl's unsaturated polyester; add the ultraviolet absorbent UV-531 (being UV-531) of 0.15 weight portion therein and do agent and stir and form the external protection resin by the sky that the styrene of the paraffin of 0.15 weight portion and 0.85 weight portion constitutes; maybe infiltration there is the glass fibre of this resin to be wound on the outside layer of above-mentioned short fiber layers this resin spraying, and adopts Far-infrared Heating curing to get final product the ectonexine of device.
In above-mentioned preparation technology, utilize spray gun that 1-2 centimetre chopped fiber is sprayed on the resin of glass fibre winding layer outer wall, the roll extrusion while spraying, thickness is chosen in the thickness that 3-5 root fiber superposes and is solidified into integrative-structure.On the basis that does not increase prepared glass reinforced plastic device thickness, improved its mechanical strength again greatly.
Owing to consist of the hollow heart layer of this glass reinforced plastic device take vinyl ester resin as major ingredient, and add therein Flexibilizer and diffusant are arranged, changed the temperature performance of vinyl ester resin, made glass reinforced plastic device Have high strength, high-wearing feature, anticorrosive and advantage that production cost is low. After tested, made glass The glass steel container can satisfy the needs that react in the ammonium sulfate workshop section and desulfurization workshop section in the coal chemical industry engineering. Above-mentioned sulphur These storage tanks that adopt composite to make in ammonium workshop section and the desulfurization workshop section have not only reduced cost, and Be better than 316L material and simple glass steel thereof from all many-sides such as decay resistance, mechanical performances, both separated The erosion-resisting problem of having determined has greatly reduced again maintenance cost.
