Solvent free epoxy coal tar bitumen cold tape (0.8mm) acceptance method 1. Inspection rule 1. Each package is packed with 10 baseband, 1 pieces of type A, B and 6 net weight per barrel. The base band is sealed with plastic film. The sizing glue is packed in plastic and barrel, then packed in carton, and carton is attached to the carton. 2. after sampling, each batch of materials can be extracted at random from 1— 2 boxes, respectively, to draw the sizing glue and the base band sizing sample: in the mixing state, at least 0.5kg is taken as the sample. Baseband sampling: intercepting the base band 0.5 to 1m as the sample. 3. test item 3.1, baseband width is measured with steel plate ruler.Steel plate ruler 100cm, accuracy 1mm. 3.2, base band tensile strength 3.2.1 instrument a) electronic tensile machine: range 1000N, precision 2N; b) steel ruler: range 500mm, precision 0.5mm. 3.2.2 test step a) take baseband test piece, 200mm x 25mm, 2 pieces. B) clamp the ends of the test piece with the wide jaw clamp of the tensile machine, and apply the pulling force slowly until the test piece breaks. C) two parallel test data were recorded, and the average value was tensile strength of the specimen. 3.3 the drying time of the molding adhesive is regulated by GB/T 1728-79 (89). 3.4 prepare a for anticorrosive layer specimen) take tinplate test piece (180mm x 60mm x 0.3mm) and cold wrap test piece (200mm x 25mm), each 5 pieces. B) use the abrasive cloth to make C on the surface of the tin plate. Mix the two ingredients of the set glue according to a: B = 1:1, mature 5min, evenly spread on the tin plate, but leave one end of the hand on the 30mm without coating. Immediately put the baseband test piece on the sizing glue, only 150mm, leave 50mm exposed outside the tinplate test piece, then apply the styling glue to the base band applied to the test piece (two times for GH403), but the base strip outside the test piece is not coated with sizing adhesive. D) the test piece made of ambient temperature glue and low temperature glue was put into the oven, dried at 6h at 60 degrees, and the serial number was 4~8. The test piece made of ultra-low temperature glue was dried at room temperature and dried in 2H, then put into oven, and dried at 40 degrees for 10h, and the serial number was 4~8. 3.5 visual inspection of the anticorrosive coating. 3.6 the thickness of the anticorrosive layer is specified in accordance with SY/T 0447-1996 5.3. 3.7 electric leakage detection for anticorrosive layer is stipulated in SY/T 0447-1996 5.4. 3.8 corrosion resistant layer adhesion 3.8.1 instrument spring scale: range 50N, precision 1N; Anticorrosive tape Polyethylene anticorrosion tapePolypropylene fiber anticorrosive adhesive tape
