Abstract
The invention discloses a method for regulating PH value of carbon black, which comprises the following steps of: (1) adding running water and an adhesive into a pelletizer according to a ratio of 10:1-50:1; (2) adding alkaline liquor into the pelletizer according to a ratio of 100:1-500:1 based on the flow of the adhesive; (3) pelletizing the carbon black through the action of stirring teeth of the pelletizer; (4) in the process of mixing the carbon black, the running water, the adhesive and the alkaline liquor, reacting the alkaline liquor with the adhesive; (5) introducing into a lifter, and feeding into a finished product storage tank; and (6) measuring the PH value of the carbon black and regulating to be the preset value. The method has the advantages that: (1) the vulcanization speed of rubber is improved, the dispersion of the carbon black in the rubber is improved, and the crosslinking between the rubber and the carbon black is increased; (2) the application range is wide; (3) the method is applied to the production of hard carbon black and is also applied to the production of soft carbon black; (4) the method is pollution-free and environmentally-friendly; (5) the method is applied to other rubber and plastic products; and (6) the carbon black belongs to general-grade carbon black products.
Description
Technical field
The present invention relates to a kind of method of adjusting pH value, relate in particular to a kind of method of adjusting the carbon black pH value.
Background technology
The general meta-alkalescence of the pH value of furnace treated black, this is that rubber industry is needed, because the sooty pH value influences the vulcanization rate of rubber, sooty pH value height can promote the sulfuration of rubber, improves vulcanization rate, PH is low for the reaction sooty, can delay the sulfuration of rubber.But at present because in the employed stock oil of carbon black/fuel gas in the rising of sulphur content, sulphur in the carbon black reaction process in the stock oil enters in the carbon black tail gas with the form of hydrogen sulfide or sulfurous gas mostly, and the employed tackiness agent of wet granulation carbon black is an acidic component, in drying process, the hot gas flow and the carbon black that with tail gas are thermal source directly reach indirect contact heat exchanger, hydrogen sulfide in the tail gas further is oxidized to sulfurous gas or sulphur trioxide, these acidic substance can be adsorbed on the sooty surface when contacting with wet carbon black particle, form sooty surface acidity group, therefore the sooty pH value descends, and detected result is for showing acid.
Summary of the invention
The object of the present invention is to provide a kind of method of adjusting the carbon black pH value, this method is included in adds a kind of unsaturated solution (as alkaline liquid XCO in the pelletizing of carbon black process
3), this solution not only can in and the acidity of the tackiness agent that adds in the carbon black process, and can be in wet carbon black drying process at wet carbon black particle surface formation barrier agent, prevention is that the acid group of thermal source is adsorbed on the sooty surface with tail gas.
The present invention is achieved like this, and it is characterized in that method steps is:
(1) tap water, tackiness agent are added tablets press with weight ratio 10:1-50:1;
(2) according to the flow of tackiness agent, with alkali lye according to the tackiness agent ratio be that the weight ratio of 1:100-1:500 adds in the tablets press;
(3) stir the effect of tooth by tablets press, the power by the control tablets press is 20-30kwh, and tap water, tackiness agent and alkali lye and carbon black are mixed, and by the mechanical effect of tablets press, carbon black is made uniform and smooth particle again;
(4) in carbon black and tap water, tackiness agent and this alkali lye blended process, this alkali lye and tackiness agent react, the acidity of the tackiness agent that neutralized, but do not reduce its bond properties; Granulated carbon black enters drying machine, carries out directly with the hot gas flow that is provided by carbon black tail gas burning, indirect heat exchange, allows the carbon black drying;
(5) the exsiccant carbon black, is discharged to the outlet of drying machine carbon black by passing behind the forward direction by the motion of rotary dryer, enters lift and is conveyed into finished product storage tank;
(6) measure the sooty pH value, and be adjusted to set(ting)value.
Described tackiness agent is maltose or xylogen.
Described alkali lye is K
