Double wall corrugated tube carbon black content tester
Double wall corrugated tube carbon black content tester
Product details
Double wall corrugated tube carbon black content testerSuitable for the determination of carbon black content in polyethylene, polypropylene, and polybutene plastics. The testing of carbon black is obtained by weight analysis of the sample after high-temperature decomposition under nitrogen protection. This instrument has the advantages of easy use, simple operation, accurate measurement, high precision, and high degree of automation. This product has obtained the national patent CN304128957S

Why test for carbon black content?
The performance of plastic products is related to the content of carbon black. Carbon black has the ability to resist ultraviolet rays. The purpose of adding carbon black to plastics is to resist aging and color matching. In fact, detecting the content of carbon black is to detect the product quality of plastic parts.

Operation method of carbon black content detector:
1. Heat the combustion boat until it is scorching hot, then cool it in a dryer for at least 30 minutes, weigh it to the nearest 0.0001g. Place a polyethylene sample of (1.0 ± 0.1) g into a combustion boat and weigh it together, accurate to 0.0001g. Subtract the weight of the combustion boat from this weight to obtain the weight A of the polyethylene sample, accurate to 0.0001g. (The dryer needs to be self equipped)
2. First, place the combustion boat containing the sample in the middle of the quartz tube of the heating furnace, and then insert a rubber plug of an exhaust glass tube into one end of the glass combustion tube. Adjust the atmosphere device to allow nitrogen with an oxygen content of less than 0.5% to pass through the quartz tube at the required flow rate, and maintain this flow rate during the subsequent heating process.
3. Move the combustion boat to the instrument port and do not immediately remove it; After the combustion boat has cooled slightly in nitrogen, remove it and cool it in a dryer for 20-30 minutes before reweighing. Subtract the weight of the combustion boat and measure the weight of the residue to the nearest 0.0001g (residue weight B).
4. Then place the combustion boat into the glass combustion tube, and in step 4, adjust the atmosphere device to replace nitrogen with oxygen at an appropriate flow rate into the quartz tube of the glass combustion tube, so that the residual carbon black is completely burned. Take out the combustion boat and cool it down, weigh it, subtract the weight of the combustion boat, and measure the weight of the residue to the nearest 0.0001g (residue weight C).
