4.Good mechanical strength after drying
Description of Acid And Wear Resistant Plastic:
Acid and wear resistant plastic refractory has good cold plasticity, small natural drying shrinkage rate, good mechanical strength after drying, excellent abrasion resistance, crack resistance, acid corrosion resistance and thermal shock resistance. It is ideal plastic refractory for garbage incinerator.
Phosphate acid or acidic aluminum phosphate is used as the binder of acid proof and wear resistant plastic refractory, clay clinker, high alumina or corundum are used as aggregate, plastic refractory clay and conservant are added into aggregate to make acid and wear resistant plastic refractory. To increase the wear resistance of plastic refractory, corundum can be used as aggregate, α-Al2O3 fine powder and micro powder can be used to increase the abrasion resistance of plastic mix.
