Many friends don’t know about acetylene black, or even what color acetylene black is. In fact, acetylene black is black like ordinary carbon black. Here I will lead everyone to get to know acetylene carbon black, so that everyone can know about acetylene black. . In order to further understand carbon black, here is also an explanation of acetylene carbon black through the difference between acetylene black and graphite.
What is acetylene carbon black?
Acetylene carbon black is a kind of carbon black. Acetylene carbon black is obtained by continuous pyrolysis of acetylene with a purity of more than 99% obtained by decomposing and refining byproduct gas during pyrolysis of calcium carbide or naphtha (naphtha) carbon black products.
What is acetylene carbon black?
Acetylene carbon black is also called acetylene black, acetylene carbon black.
What is acetylene carbon black?
Acetylene carbon black is a kind of conductive carbon black.
Contract acetylene carbon black quality index
Heating loss/%: ≤0.40
Ash/%: ≤0.30
pH value: 6-8
Apparent volume mL/g: 30～50
Iodine absorption value/(gI2/kg): ≥80
Hydrochloric acid absorption mL/g: 4.0
Resistivity/Q m: ≤3.0
What is acetylene carbon black used for?
Acetylene carbon black is used as an antistatic agent, mainly used in dry batteries as a liquid absorbent, and also used in conductive, antistatic and thermally conductive rubber products, as well as conductive coatings and plastic products. Adding it to the emulsion of acrylate/vinyl acetate copolymerization can make electrostatic conductive emulsion pressure-sensitive adhesive. When the addition amount is 1.2%, the conductivity can reach 7.2×103Q, which can be used to paste static conductive PVC floor. It is also used as a conductive filler to prepare conductive adhesives that do not require high conductivity.
Is acetylene black graphite cracked by acetylene?
In appearance, acetylene black and graphite are almost the same, both are black powder, but there is a big difference between the two. Acetylene black and graphite are actually an allotrope of carbon, but there are some differences between acetylene black and graphite.
