补充资料:石油产品针入度
分子式:
CAS号:

性质:又称石油产品推入度(cone penetration of petroleum products)。润滑脂、石油沥青和石油蜡的稠度(或硬度)的一种量度。是他们的主要质量指标,并作为划分牌号的依据。在规定温度、荷重、时间下,标准针体或锥体垂直穿入试样的深度,以1/10mm表示。使用针体时称针入度。使用锥体时称锥入度。锥(针)入度越大,稠度越小,试样越软。反之,锥(针)入度越小,稠度越大,试样越硬。润滑脂还有用微锥入度(micro cone penetration)或块锥入度(block cone penetration)来表示其稠度的。微锥入度系在规定条件下,采用组合尺寸为标准体1/4的小锥体测得的润滑脂锥入度。适用于测定少量的润滑脂样品。微锥入度(B)与一般锥入度(A)的关系式可以表示为A=3.75B+24。块锥入度是指硬度足以保持其形状的润滑脂在25℃时测得的锥入度。适用于测定稠度较大的润滑脂产品。
