Remarkably , the temperature must be limited between softening point and solidification value , at which the bond can get perfect fluidity and stickiness . effects of bond content and pressure on magnet product during heating - pressing process are the same with effects during common - pressing process . fourthly , it is more than 250 hours before magnet is eroded when it is coated with lacquer by way of cathode electrophoresis 溫度對溫壓效果影響明顯,應(yīng)當(dāng)選擇在粘結(jié)劑軟化點以上、固化反應(yīng)前的某一點,保證粘結(jié)劑具有適當(dāng)?shù)恼扯群土己玫牧鲃有?;與普通壓制工藝相同,溫壓工藝制備的粘結(jié)磁體密度和磁性能均隨壓制壓力的增大而提高,磁體性能和磁粉體積分數(shù)隨粘結(jié)劑含量變化的規(guī)律一致。
