2017-3-21 23:48:54
Cavitation erosion resistant coatings with crosslinking agent,Cavitation erosion resistant coatings used in the development of the resin, the composition of main materials, production of as shown below. NBR (Acrylonitrile - butadienerubber) of modified epoxy resin, Glass scale piece (big small: um 100 Glass Flake (UK), epoxy softening agent (Air Products (USA), paint (Glass Flake, colloidal calcium carbonate, carbon dioxide, such as layered silicate ceramic pigment), amino silane (Dow Corning (USA).
Crosslinking agent polyether amine and polyamide, amine promoting agent, defoamer, TiO 2. Material equilibrium mixing.
In order to evaluate physical coating, the first to use coater evenly on the stainless steel plate coating 2 mm thick coating. Test plate under the environment of 25 ℃ in 48 hours after drying, the physical properties of the coating that is, the strength, adhesive strength, corrosion resistance, resistance to cavitation erosion.
Performance measurement in table 2 and table 3 tensile shear str
ength, adhesive strength, adhesion, extension and strength, surface hardness, standard test method for implementation of cavitation erosion, the following account for part of the test method.
In addition compound salt spray test (corrosion evaluation) is according to fill in the nano in NBR modified epoxy resin piece. The results in table 3 and table 4 detailed records. Especially the cavitation erosion test the surface of the test plate photos with cavitation erosion test after wear is the determination of value according to the quantitative.
Adhesion strength (ASTM D4541). Adhesion to test the adhesion tester were tested using the open method. This tester is the top of riveting machine into a spherical, drawing was carried out on the test surface tension and vertical storage.
Adhesion test board general material is carbon steel, the thickness of 3.2 mm. Vacuum down after the bubbles and volatile component, on the adhesion of coating, some time after drying under the conditions of completely hardening production test plate, and a test was carried out.
Wear resistance (ASTM D4060). Use Taber abrasion tester (Taber Abraser) according to the standard test method for the test of wear resistance of organic coatings, while the low reproducibility test method, the test for abrasion resistance parameters have certain restriction, but this study is to use this method to compare the cavitation erosion lead to wear and tear of the interconnectedness of the experiment.
Compound ageing cycle test (RS KCL, 2002, 0008, KSM ISO11997-1). To evaluate research the influence of glass flake filler to be able to bear or endure corrupt sex, make fill in NBR modified epoxy resin with tabular inorganic material suitable or unsuitable, for 1 ~ 4 phases with a surface observation cycle repeated test. This experiment was carried out in 50 cycles (300 hours).

The determination of cavitation erosion (ASTM G32-98 variant Type transfering). For cavitation erosion evaluation method is widely used at home and abroad of ASTM G32, transfering ASTM G134 and barrels of cavitation test method.
Employed in this study is representative of the ASTM test method of G32 retrofit transfering, especially on the test plate fixed position adjustment to improve. The original test methods for vibrating hammer strong vibration, the coating finish of specimens drops out, or according to the different methods such as vibration hammer winding value carries on the analysis of the different result.
But because of the low reliability of this method, thus began to hammer is widely adopted and vibration isolation type fixed plate of improved after a distance evaluation method.
Test plate is 20 mm wide, length of 20 mm, thickness is 5 mm, material is 304 stainless steel, and the coating according to the thickness of 2.0 + / - 0.1 mm, vibration amplitude of the 20 KHZ, 50 um ultrasound machine assembly under the angular equipment (Horn), began to launch after ultrasound test.
Test solution for distilled water, solution depth at least to maintain for more than 100 mm, the depth of the test plate dipping position for 12 + 4, test plate center shaft within + / - 5 for installation. Test temperature maintained according to 25 + 2 ℃.
