This paper reports a polishing disk which can substitute for rare earth. Using alumina - cerium oxide core-shell composite abrasive as abrasive, unsaturated resin as bonding agent, abrasive tool can be prepared by adding a water soluble pore-forming agent, suitable heat absorbing agent and active stuffing and the suitable addition amounts which are 25.6%, 46.8%, 18.5%, 3.8% and 1.2%, respectively .This abrasive tool can conduct the temperature in the grinding zone rapidly. It also has high grinding efficiency smooth polishing surface and without cracks or scratches, which meet furthermore, it has the merits of low cost and extensive use prospect. The polishing effect of rare earth polishing disk, but the low cost make it suitable for wide promotion.

Using coarse-grained dissipative particle dynamics (DPD) with explicit electrostatics, we performed (i) an extensive series of simulations of the electrostatic co-assembly of asymmetric oppositely charged copolymers composed of one (either positively or negatively charged) polyelectrolyte (PE) block A and one water-soluble block B and (ii) studied the solubilization of positively charged porphyrin derivatives (P+) in the interpolyelectrolyte complex (IPEC) cores of co-assembled nanoparticles. We studied the stoichiometric mixtures of 137 A10+B25 and 137 A10−B25 chains with moderately hydrophobic A blocks (DPD interaction parameter aAS=35) and hydrophilic B blocks (aBS=25) with 10 to 120 P+ added (aPS=39). The P+ interactions with other components were set to match literature information on their limited solubility and aggregation behavior. The study shows that the moderately soluble P+ molecules easily solubilize in IPEC cores, where they partly replace PE+ and electrostatically crosslink PE− blocks. As the large P+ rings are apt to aggregate, P+ molecules aggregate in IPEC cores. The aggregation, which starts at very low loadings, is promoted by increasing the number of P+ in the mixture. The positively charged copolymers repelled from the central part of IPEC core partially concentrate at the core-shell interface and partially escape into bulk solvent depending on the amount of P+ in the mixture and on their association number, AS. If AS is lower than the ensemble average ⟨AS⟩n, the copolymer chains released from IPEC preferentially concentrate at the core-shell interface, thus increasing AS, which approaches ⟨AS⟩n. If AS>⟨AS⟩n, they escape into the bulk solvent.
