本文以现有硬质合金模压成型剂为参照,进行了新研制的CSZ成型剂的溶解、压制、烧结等应用性能研究。实验表明该成型剂能与酒精相溶,粘度低,适合喷雾干燥。制备的混合料细而软,流动性好,能够直接压制石蜡、PEG等喷雾料难成型的复杂形状的制品。压制压力较PEG降低20%,有效减少压坯分层、裂纹等缺陷,是一种比较理想的新型硬质合金模压成型剂。
In this paper, the existing carbide molding agent as a reference, the newly developed CSZ molding agent dissolution, pressing, sintering and other application properties. Experiments show that the molding agent can be compatible with alcohol, low viscosity, suitable for spray drying. The prepared mixture is fine and soft, has good fluidity, and can directly suppress the complicated shaped products such as paraffin, PEG sprayed material difficult to mold. The pressing pressure is reduced by 20% compared with that of PEG, which effectively reduces defects such as delamination and cracking of compacts, and is an ideal new type of hard alloy molding agent.
