Description
Technical field
The present invention relates to a kind of super abrasion resistant carbon black and production technique thereof of mixing easy dispersion.
Background technology
Carbon black be many hydrocarbons (solid-state, liquid, gaseous state) at high temperature, the unformed charcoal of producing through the incomplete combustion cracking.Carbon black specific surface is very wide, and because its production method is different, the physicochemical property of carbon black also difference are very large.At present, super abrasion furnace black quality product also quality differs, and the shortcoming of this series product concentrated expression is exactly that mixing energy consumption is high, difficulties in dispersion, and calendering and extrusion are difficult etc.
Summary of the invention
The super abrasion resistant carbon black and the production technique thereof that the purpose of this invention is to provide a kind of mixing easy dispersion.
The technical scheme that the present invention takes:
A kind of super abrasion resistant carbon black of mixing easy dispersion, it is that carbolineum take weight ratio as 3:2～9:1 and the mixture of coal tar are stock oil, and salt of wormwood is additive, and Sweet natural gas is fuel, adopts super abrasion furnace black oven process production technique to be prepared from; Wherein the mass ratio of stock oil and additive is 245:1～275:1.
The production technique of described super abrasion resistant carbon black, its concrete steps are as follows:
The air that (1) will be compressed to 165～190Kpa is preheating to 700～800 ℃ through air preheater, delivers to the distribution plenum of Reaktionsofen through the hot blast pipeline;
(2) described fuel and additive are sent into the combustion chamber of Reaktionsofen, with the warm air mixed firing that above-mentioned distribution plenum is sent, temperature is controlled at 1900～1927 ℃.Described stock oil is sprayed into by the trunnion section of Reaktionsofen after the fuel oil preheating device is preheated to 180～260 ℃, through atomizing, shear, carries out the scission reaction of 6～20 microseconds at the conversion zone of Reaktionsofen, produces carbon black smoke;
(3) described carbon black smoke carries out chilling one time at the Reaktionsofen quench zone, passes through successively air preheater and fuel oil preheating device again, carries out at last the secondary chilling, makes flue-gas temperature be down to 260～290 ℃;
(4) carbon black smoke after the cooling enters main bag filter and collects, and the carbon black of collection is pulverized through micron disintegrator and delivered to the collection cyclonic separator by the wind fan;
(5) carbon black of described cyclonic separator collection is through granulator granulation, and the particle diameter that makes carbon black particle is 0.5-1.4mm, and the drying machine is dry again gets final product.
The most significant advantage of the present invention is: the present invention is take Sweet natural gas as fuel; coal tar, carbolineum are mixed into stock oil with suitable proportion; the stock oil that adopts is rational in infrastructure; carbon yield is higher, the minimum and narrow distribution of carbon black products particle diameter of producing, and structure is lower; the powdery carbon black makes behind micron disintegrator, tablets press, drying machine; and mature preparation process is fit to industrialized production, has significant economic benefit.
Carbon black products of the present invention (called after LX-LS100) belongs to super abrasion furnace black, has the advantages such as reinforcing property is high, wear resisting property is fabulous, has also improved simultaneously high, the difficulties in dispersion of the mixing energy consumption of super wear-resisting serial carbon black, the shortcoming that calendering and extrusion are difficult for.LX-LS100 carbon black particle of the present invention disperses grade point can reach about 7 grades, and the N110 carbon black particle that belongs to super abrasion furnace black together disperses grade point generally about 5 grades, can find out from above-mentioned separate data, LX-LS100 disperses grade point high by about 40% than common super abrasion furnace black, has namely well improved the shortcoming of the mixing difficult dispersion of super wear-resisting serial carbon black.
LX-LS100 carbon black products index of the present invention is as follows:
