如何解决钢板在运输过程中的防锈问题

文章发布: 发表时间:2017-07-18 10:21:56

解决冷轧钢板在贮运过程中的防锈疑问,应当研讨开发兼具气相防锈功能的防锈油,本着经济实用的原则,对防锈油系统进行改善,选用气相防锈油,行将少数的气相缓蚀剂(VPI)溶于基础油中,缓蚀剂气体便会以必定的蒸气压充满封存空间,因为气体的无孔不入性,缓蚀剂气体分子均可被吸附到露出的钢板外表,从而起到防锈效果。

To solve the question of cold rolled steel plate rust during storage and transportation, should study develop both gas phase antirust function of antirust oil, with economic and practical principles, to improve the anti rust oil system, the gas phase antirust oil, is a gas phase inhibitor (VPI) dissolved in the base oil, gas corrosion inhibitor in certain vapor pressure full storage space, because get in by every opening of gas, the inhibitor can be adsorbed gas molecules to the exposed steel surface, so that the anti rust effect.
由Henry规律可知,气相缓蚀剂的性质(如:饱满蒸气压、稳定性)、基础油的性质(如:粘度、挥发性)和气相缓蚀剂的含量直接影响着气相缓蚀剂在防锈油中的蒸气压及气相防锈能力。有效的触摸缓蚀能力是防锈油的基本功能。以石油磺酸钡为主、司本-80为辅的油溶性缓蚀剂具有优良的触摸缓蚀功能[1]。一般冷轧钢板的防锈封存都需求最少维持半年,因而有必要请求增加的气相缓蚀剂在金属外表上具备敏捷起效果与长时间保持的功能。一起为保证缓蚀剂在水膜中能到达必定的浓度,以充分发挥其缓蚀效能,气相缓蚀剂应是水溶性的。
By Henry law shows that the properties of the vapor phase inhibitor (such as: full vapor pressure, stability), properties of base oil (such as viscosity, volatile) vapor pressure and gas content and gas phase corrosion inhibitor directly affects the gas phase corrosion inhibitor in the rust proof oil phase anti rust capability. The effective touch and corrosion resistance is the basic function of antirust oil. Oil soluble inhibitors, supplemented by petroleum barium sulfonate and -80, have excellent corrosion inhibition function. [1]. Generally, cold rolled steel sheets need to be maintained for at least half a year, so it is necessary to request additional vapor corrosion inhibitors to have quick and long lasting effects on the metal surface. In order to ensure that the inhibitor reaches a certain concentration in the water film, in order to give full play to its corrosion inhibition efficiency, the gas phase inhibitor should be water-soluble.
实验方法
Experimental method
考虑到储运过程中也许遇到高温、高湿气候要素,采纳静态湿热实验评估气相防锈油DZL的触摸缓蚀功能。试样原料选用20#碳钢;经打磨、清洁和涂油处理后将试样挂入枯燥器中;枯燥器底部加蒸馏水,最终全部设备放入恒温水浴中。
Taking into account the possible high temperature and high humidity climatic factors during storage and transportation, a static heat moisture test was adopted to evaluate the corrosion inhibition function of DZL. The sample material is made of 20# carbon steel. After grinding, cleaning and oiling, the sample is put into the drying device. The bottom of the drying machine is distilled water, and finally all the equipment is placed in the constant temperature water bath.
