The traditional making method uses the sodium silicate, silicon tetrachloride and ethyl orthosilicate as the silicate source to make. But it has high cost, so there is the new making method, that uses the cheap non-metal mine as the silicate source. The both methods also need following processes: neutralize, precipitate, filtration, washing and drying. For filtration, the filter press is the best filtering equipment.


To making white carbon black, the raw material mainly includes: aedelforsite, opal, olivine, ophiolite, kaolin and the coal ash etc.Because the white carbon black is the very fine, so, generally, we recommend the membrane filter press. The membrane filter press can be squeezed secondly to get the lowest filter cakes moisture and also decrease the subsequent running cost.
