意大利宁柏迪公司成功研发并向市场提供了牌号为罗菲尔 PP/MP/75的专用于水泥增强的丙纶短纤油剂。其化学成份为数种经加工的脂族类化合物的混合物。外观为乳液,非离子或微阴离子特性;PH 值为8。目前向市场供货的产品中活性物质含量为25%左右;在温水中分散性良好。该产品可在混凝土、砂浆和喷射混凝土、干拌灰浆和水泥干拌料,预制件中用作水泥制品添加剂。由于这种纤维的用量少,对混凝土和灰浆的料比、粘度等均无影响,故适用于上述三类水泥产品的所有应用领域。在欧洲,已用于机场跑道、停机坪、隧道內壁、排水系统、民居院落、停车场、建筑物面层等。丙纶短纤呈单个纤维均匀地分布在混凝工中,其表面处理需用专用油剂。罗菲尔 PP/MP/75就是这样一种专用油剂,适用于水泥增强的丙纶纤维。其特点为:热稳定性好;在水乳液中,活性物质颗粒大小很好地保障了纤维表面的涂敷;使经处理的纤维达到最佳,恰当的平衡点:纤维与纤维、纤维与金属间的摩擦力,抗静电性和抱合力之间;处理过的纤维,即使长期存放亦不变黄,也不产生异味。水泥制品中的裂缝,会影响强度和使用寿命,亦使人失去安全感。裂缝产生的原因,解释为局部存在 Ningbodi Company of Italy successfully developed and provided the market with a brand name of Roefeel PP / MP / 75 for cement-reinforced polypropylene staple oil. Its chemical composition is a mixture of several processed aliphatic compounds. The appearance of emulsion, non-ionic or micro-anion properties; PH value of 8. Currently available in the market of products active substance content of about 25%; good dispersion in warm water. The product can be used in concrete, mortar and shotcrete, dry mortar and cement dry mix, prefabricated parts for cement additives. Due to the small amount of fiber, concrete and mortar material ratio, viscosity, etc. have no effect, it is applicable to all three types of cement products applications. In Europe, it has been used in airport runways, apron, inner wall of tunnel, drainage system, residential courtyard, parking lot, building surface and so on. Polypropylene staple fibers were evenly distributed in the coagulation of a single fiber, the surface treatment required special oil. Rofeil PP / MP / 75 is such a special oil, for cement-reinforced polypropylene fiber. Its characteristics are: good thermal stability; in the water emulsion, the particle size of the active material well protect the coating of the fiber surface; the treated fiber to achieve the best, the right balance: fiber and fiber, fiber and metal Between the friction, antistatic and cohesion; processed fiber, even if the long-term storage does not turn yellow, nor produce odor. Cracks in cement products will affect the strength and service life, but also make people lose their sense of security. The reason for the crack is explained as a local existence
