如何解決鋼板在運輸過程中的防銹問題

文章發布: 發表時間:2017-07-18 10:21:56

解決冷軋鋼板在貯運過程中的防銹疑問,應當研討開發兼具氣相防銹功能的防銹油,本著經濟實用的原則,對防銹油系統進行改善,選用氣相防銹油,行將少數的氣相緩蝕劑(VPI)溶于基礎油中,緩蝕劑氣體便會以必定的蒸氣壓充滿封存空間,因為氣體的無孔不入性,緩蝕劑氣體分子均可被吸附到露出的鋼板外表,從而起到防銹效果。

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規律可知,氣相緩蝕劑的性質(如:飽滿蒸氣壓、穩定性)、基礎油的性質(如:粘度、揮發性)和氣相緩蝕劑的含量直接影響著氣相緩蝕劑在防銹油中的蒸氣壓及氣相防銹能力。有效的觸摸緩蝕能力是防銹油的基本功能。以石油磺酸鋇為主、司本-80為輔的油溶性緩蝕劑具有優良的觸摸緩蝕功能[1]。一般冷軋鋼板的防銹封存都需求最少維持半年,因而有必要請求增加的氣相緩蝕劑在金屬外表上具備敏捷起效果與長時間保持的功能。一起為保證緩蝕劑在水膜中能到達必定的濃度,以充分發揮其緩蝕效能,氣相緩蝕劑應是水溶性的。
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.
實驗方法
Experimental method
考慮到儲運過程中也許遇到高溫、高濕氣候要素,采納靜態濕熱實驗評估氣相防銹油DZL的觸摸緩蝕功能。試樣原料選用20#碳鋼;經打磨、清潔和涂油處理后將試樣掛入枯燥器中;枯燥器底部加蒸餾水,最終全部設備放入恒溫水浴中。
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.
