2. At the same time, it has the effect of cohesive sedimentation, reducing the filter bag load and pulse frequency.
3,.Filter bag mouth adopts elastic expansion ring seal. With good tightness, convenient disassembly. The frame is resistance welded.
4. The outer surface is smooth without weld marks, which solves the problem of filter bag and frame wear. The filter bag has a long service life.
5. According to the working environment, choose filter materials with different performance and specifications. The running resistance is stable, the energy consumption is low, and the dust removal efficiency is greater than 99.9%.
Wire and cable rubber combustion test
Rubber carbon black content tester test experiment process
1. Heat the combustion boat until it is hot, then cool in a desiccator for at least 30 minutes and weigh to the nearest 0.0001g. (1.0 ± 0.1)g of polyethylene samples were placed in a combustion boat and weighed together to the nearest 0.0001 g. The weight of the burning boat was subtracted from that weight to obtain the weight A of the polyethylene sample, accurate to 0.0001. g. (dryer need to be equipped with)
2. First place the burning boat with the sample in the middle of the quartz tube of the heating furnace, then insert a rubber stopper of the exhaust glass tube into the end of the glass combustion tube, and adjust the atmosphere device so that the oxygen content is less than 0.5%. Nitrogen flows through the quartz tube at the required flow rate and maintains this flow rate during subsequent heating.
3. Move the combustion boat to the mouth of the instrument and do not remove it immediately. After the combustion boat is cooled slightly in nitrogen, remove the burning boat, then cool it in a desiccator for 20-30 minutes and reweigh, minus the weight of the burning boat. Measure the weight of the residue to the nearest 0.0001g (residue weight B).
4, then the combustion boat put the glass combustion tube, in step4 adjust the atmosphere device will replace the nitrogen gas at an appropriate flow rate of nitrogen to the glass tube in the quartz tube, so that the residual carbon black is completely burned. Take out the combustion boat and cool it, weigh it, subtract the weight of the boat, and measure the weight of the residue to the nearest 0.0001g (residue weight C).
