The effects of different factors on the rheological properties of abrasive suspension were experimentally conducted by measuring the rheological parameter of abrasive suspension,which polyacrylamide(PAM), garnet and steel grit were selected as additive and abrasive respectively in the field of descaling of abrasive suspension jet. The results show that, abrasive concentration and abrasive grit have little influence on the viscosity of suspension. The garnet and steel grit, abrasive slurry viscosity change c...
