01 PANGEL B5——矿物类增稠剂
PANGEL B5 is a morphologically microfibrous rheological additive obtained by the organic modification of highly refined sepiolite with a high degree of deagglomeration.
PANGEL B5是一种针状纤维状的流变添加剂，是通过对高纯度的海泡石进行有机改性而获得的，具有高度的分散性。
PANGEL B5 is specifically designed for use as a thickener in mineral oil based lubricant greases.
PANGEL B5是专门为矿物油基润滑脂中的增稠剂而设计开发的。
02 PANGEL B5——在矿物油中的应用介绍
PANGEL B5 is a product designed as a highly efficient thickener in mineral oil bases. The paraffin oil used in this study had a viscosity of 220 cSt at 40ºC and a high viscosity index.
PANGEL B5是一种专为矿物油基开发的高效增稠剂产品。在实验中，添加到矿物油（在40℃下的运动粘度为220 cSt）中可以得到高粘度指数的润滑脂产品。
The graph shows that consistent greases pertaining to NLGI grades #2 to #2.5 (24h) are obtained with a paraffin mineral oil base with medium-high viscosity (220 cSt at 40 ºC) at dosage levels of 8-10%. When grease was worked at 60 strokes, penetration increased 5-6% to give a grade #2 consistency. A linear increase in viscosity was observed in the dosage levels of PANGEL B5 studied.
下图显示，在8-10%的添加量，PANGEL B5能达到美国润滑脂协会（NLGI等级 #2至 #2.5）（24小试）的润滑脂指标。当润滑脂以60次冲程工作时，渗透增加了5-6%，达到2级稠度。在所研究的PANGEL B5 的剂量水平中观察到粘度的线性增加。
03 PANGEL B5的特点
The use of PANGEL B5 as a thickening additive for mineral oil bases contributes:
使用PANGEL B5作为矿物油基增稠添加剂有助于：
- A high thickening efficiency that achieves high consistencies at low dosage levels.
- 在低添加量水平下实现高稠度的高增稠效率。
- A decrease in the amount of thickener needed to reach the desired viscosity, which produces a significant increase in the shine and transparency of the grease.
- 减少达到所需粘度所需的增稠剂的量，这会显著提高润滑脂的光泽度和透明度。
- PANGEL B5 is designed to develop maximum thickening capacity in base oils with no need for help from polar activators.
- PANGEL B5旨在扩大基础油的最大增稠能力，而不需要极性活化剂的帮助。
- PANGEL B5 provides a significant economic advantage in comparison with organophilic bentonites due to the different chemical modification process by which the product is obtained.
- 由于该产品的化学改性工艺不同，与其他的有机膨润土相比PANGEL B5具有显著的经济优势。
04 PANGEL B5与有机膨润土的比较
The following graph shows a comparison of the thickening effect of PANGEL B5 at dosage levels of 8% and 9%, compared to commercial organophilic bentonites at concentration levels of 8%. The resulting greases have an NLGI #2 consistency.
下图显示了PANGEL B5在8%和9%添加量的增稠效果与8%浓度水平下的商业亲有机膨润土的比较。所得润滑脂具有NLGI#2稠度。
Greases thickened with organobentonites were produced according to the manufacturer’s recommendation, using a 30% by clay weight of a polar activator (methanol:water 95:5).
如果使用有机膨润土生产润滑脂，一般需要有机膨润土重量30%的极性活化剂（甲醇/乙醇:水95:5）生产用有机膨润土增稠的润滑脂。
- PANGEL B5 has been designed to eliminate the need for adding a polar activator and thereby provides economic and technical benefits by simplifying the grease production process.
- PANGEL B5的设计旨在消除极性活化剂，从而通过简化油脂生产过程提供经济和技术效益。
- PANGEL B5 offers an excellent cost/efficiency ratio in comparison with other organophilic clays.
- 与其他有机膨润土相比，PANGEL B5具有优异的成本效益比。
05 不同油脂添加剂对PANGEL B5的影响
Studies were made of what effect the introduction of additives with varying chemical compositions commonly used in grease formulation had on the consistency of greases thickened by PANGEL B5. The results are shown in the following graph.
研究在润滑脂配方中引入不同化学成分的添加剂对PANGEL B5增稠润滑脂稠度的影响。结果如下图所示。
A grade #2 consistent grease was prepared with an 8% dosage level of PANGEL B5 and its viscosity and consistency were measured after 24 hours. The amounts recommended by the manufacturer of the additives mentioned in the graph were added to this additive free grease.
用8%添加量的PANGEL B5制备2级稠度润滑脂，并在24小时后测量其粘度和稠度。将图表中提到的添加剂制造商推荐的量添加到这种无添加剂的润滑脂中。
- It was seen that the additives used did not have a significant effect on PANGEL B5’s thickening capacity. Only the anticorrosion additive (a solid product added in a larger proportion) caused an increase in viscosity and a decrease in the degree of penetration.
- 可以看出，所使用的添加剂对PANGEL B5的增稠能力没有显著影响。只有防腐添加剂（以较大比例添加的固体产品）导致粘度增加和锥入度。
- PANGEL B5 can be used as a thickening agent for mineral oil bases to replace organophilic bentonites. It is designed especially for paraffin oils.
- PANGEL B5可用作矿物油基的增稠剂，以替代有机膨润土。它是专门为矿物油设计的。
- PANGEL B5’s high thickening efficiency enables reaching the consistency values required at low dosage levels. This lowers the cost of the grease and improves its optical properties:shine and transparency.
- PANGEL B5的高增稠效率能够在低剂量水平下达到所需的稠度值。这降低了润滑脂的成本，并改善了其光学性能：光泽和透明度。
- PANGEL B5 achievesits maximum efficiency under optimum dispersion conditions:
①High shear (18-25m/s)，
②Colloidal mill dispersion
- PANGEL B5在最佳分散条件下达到最高效率：
① 高速剪切：(18-25m/s)
② 三辊机/胶体磨分散
- Unlike many organophilic bentonites, PANGEL B5 does not require the use of a polar activator to develop maximum viscosity and therefore it simplifies the grease production process.
- 与许多有机膨润土不同，PANGEL B5不需要使用极性活化剂来产生最大粘度，因此简化了润滑脂的生产过程。
