XH-420-75L密煉機     XH-420 Lab Internal Mixer

簡介：本機適用于塑料、橡膠、合成膠、熱熔膠及各種低粘度物料等各式化學原料的攪拌、捏合、分散。

Introduction: This machine is suitable for mixing, kneading and dispersing of various chemical raw materials such as plastic, rubber, synthetic rubber, hot melt adhesive and low viscosity materials.

工作原理：由兩支表面帶螺旋棱角的攪葉軸，封閉在“W”形容室內，在一定壓力與溫度條件下，兩軸做相對差速運轉，使膠料攪拌分散。

Working principle: Two agitator shafts with spiral edges on the surface are enclosed in the 'W' chamber. Under certain pressure and temperature conditions, the two shafts are operated at a relatively different speed to stir and disperse the materials.

75L密煉機通過一對相對回轉的轉子，在密閉且可調溫壓的密煉室內對聚合物材料進行塑煉和混煉。其核心工作過程如下：

1. 物料混合：生膠或配合劑從加料斗加入后，落入兩個相對回轉的轉子上部，在上頂栓的壓力及摩擦力作用下被帶入轉子間隙。

2. 剪切與捏煉：物料在轉子間隙、轉子與密煉室壁間隙中受到強烈的剪切、摩擦和捏煉作用，配合劑被均勻分散，膠料溫度升高，粘度降低。

3. 循環混煉：物料在轉子不同速度的影響下反復循環，直至達到所需的物理和化學性能。
