Embodiment 1
[0037] A high-strength corrosion-resistant industrial filter cloth, which includes the following steps:
[0038] Step S1: PET polyester slice, enhanced particles, corrosion resistant particles, plasticizer to the extruder, melt extruded, prepared polyester fibers;
[0039] Step S2: Wove the polyester fiber into the fabric to make a high strength corrosion resistant industrial filter cloth.
[0040] The enhanced particles are made of steps:
[0041] Step A1: Add trichloride and carbon tetrachloride to the reaction kettle, at a temperature of 150 r / min, the temperature is 10 ° C, stirring and added nitrobenzene, reacting at a temperature of 40 ° C. 1H, the intermediate body 1 is obtained, and the intermediate 1, iron powder, ethanol is added to the reactor, and after reflowing at a temperature of 80 ° C, the hydrochloric acid solution is added, and the solution is 20 min, and the reaction is continued for 5 hours. The reaction liquid pH is 7, and the intermediate 2 is produced, an...
