2The hydrate that O is precipitated out through washing, press filtration, be dried to finished product.The leading indicator of last quality product is a burning decrement, and the burning decrement index of white carbon black is to being that the quality product of raw material has decisive influence with it, so different industries such as carrier, tire, agricultural chemicals, coating etc. require different to the burning decrement of product.The technology of existing production white carbon black can't accurately be controlled the burning decrement index of the white carbon black product produced, so cause the burning decrement indication range of product bigger, can't satisfy requirements of different users.
Summary of the invention
The present invention provides the method for precisely control product burning decrement in a kind of producing white carbon black using settling method process in order to solve the problem that can't accurately control the burning decrement of product in the producing white carbon black using settling method technology that exists in the prior art.
The present invention is realized by following technical scheme, the method of precisely control product burning decrement in a kind of producing white carbon black using settling method process, it is that yellow soda ash and quartz sand reaction generate water glass that step comprises raw material, the further building-up reactions of the water glass and the vitriol oil generates sodium sulfate and white carbon black then, carry out stepped control by modulus to the water glass that generates, controlled temperature is at 80～95 ℃ in building-up reactions then, and the concentration of water glass is controlled at 2.2～2.8mol/L.Optimal conditions are: controlled temperature is at 85～90 ℃ in the building-up reactions, and the concentration of water glass is controlled at 2.4～2.6mol/L.
The modulus of the sodium silicate raw material of white carbon black production is distinguished classification with 3.10-3.20,3.20-3.30,3.30-3.40 three phases, and its realization is with realization by the raw material quartz sand when producing water glass and soda ash proportioning ratio different.The present invention only does effective adjustment to operating procedure on the technology basis of existing producing white carbon black using settling method, and need not change the original production line and the production unit of use, the burning decrement of the white carbon black of producing can be controlled at 3～4 respectively, 4～5,5～6 grades accurately among a small circle in, can satisfy requirements of different users.The burning decrement of the wetting ability white carbon black that precipitated silica makes and the modulus of sodium silicate raw material are inversely proportional to.
The calculating of modulus (M): modulus (M) is the ratio of silicon-dioxide mole number and sodium oxide mole number in the product, is calculated as follows: M=X4/X3 * 1.032
In the formula: X3 ... sodium oxide (Na
2O) percentage composition
X4 ... silicon-dioxide (SiO
2) percentage composition
1.032 ... the ratio of sodium oxide relative molecular weight and silicon-dioxide
