食品网带、长城网带、链条网带的表面清洁与保养    

1. 不锈钢网带钝化膜属于热力学上受抑制的亚稳态布局口其掩护效能与情况介质有关。利用中应活期洗濯,撤除无害物质恒久私附在外貌上。的内涵要素。不锈钢中马氏体含量和铬镍含量对不锈钢的钝化功能影响很大。镍含量低下,钝化功能就低。马氏体不锈钢的钝化膜功能不如奥氏体不锈钢的钝化功能。  

2.氯离子   

氯离子对不锈钢网带的危害极大。在钝化历程中应严酷控制钝化液中氯离子含量,所用钝化用化学质料对氯离子都有限量要求。配制钝化液用水和洗濯用水也对氯离子有严酷的水质要求,以保证钝化成品不沾附氯离子,以免后患。   

3.利用情况介质   不锈钢网带钝化膜属于热力学上受抑制的亚稳态布局口其掩护效能与情况介质有关。利用中应活期洗濯,撤除无害物质恒久私附在外貌上。尤其是在有氯离子的情况中,避免氯离子恒久乳附外貌和在水中稀释口如不锈钢用于食品上业用具,每次与食品接触后,都要洗净,以免氯离子作用,损害钝化膜。不锈钢网带钝化膜属于热力学上受抑制的亚稳态布局口其掩护效能与情况介质有关。利用中应活期洗濯,撤除无害物质恒久私附在外貌上。如用于乳成品的容器和设置装备摆设,乳品中含有氯离子对钝化膜有粉碎作用,如恒久艳服乳成品,会导致容量与设置装备摆设腐蚀穿孔,因而要活期洗濯,使钝化膜恢复。   4.外貌清洁度   对子不锈钢合金,外貌粗糙度越低,外貌越平滑,异物越难翁附,各部部分腐蚀的几率越低。因而,不锈钢应尽大概采用精加工外貌。此外,不锈钢外貌清洁度也很紧张,钝化后的最终洗濯应细致举行,由于残余酸液促进阴极反响,使膜层破碎,从而使不锈钢活化,耐蚀功能猛烈降低。

       The surface of the stainless steel mesh belt cleaning and maintenance 1. Stainless steel mesh belt on the passivation film belongs to the thermodynamic inhibition of metastable layout mouth about its effectiveness and cover medium. Use of current washing, removal of harmless substance permanent private attached to the appearance. The connotation of the elements. Content of the martensite content of chromium and nickel in stainless steel had a great influence on function of the passivation of stainless steel. Low nickel content, passivation function are low. Martensite stainless steel passivation membrane function than austenitic stainless steel passivation function. 2. The chloride ion chloride to the harm of stainless steel mesh belt is great. Should be strict control in the passivation process of chlorine ion in the passivation solution, the passivation with chemical material used for chloride ions are limited. Preparation passivation liquid water and washing water also has severe water quality requirements to the chloride ion, to ensure that the passivation products not cleave the chloride ion, in order to avoid future trouble. 3. The use of medium stainless steel mesh belt passivation film belongs to the thermodynamics on inhibition of metastable layout mouth about its effectiveness and cover medium. Use of current washing, removal of harmless substance permanent private attached to the appearance. Especially in the case of the have a chloride ion, avoid the chloride ion permanent breasts are attached to the appearance and diluted in water mouth, such as stainless steel utensils used in food industry, every time after contact with the food, all want to wash, so as to avoid the chloride ion, damage the passivation film. Stainless steel mesh belt passivation film belongs to the thermodynamics on inhibition of metastable layout mouth about its effectiveness and cover medium. Use of current washing, removal of harmless substance permanent private attached to the appearance. Such as container and set the decoration equipment for milk products, dairy products contain chlorine ions have a crushing effect on passive film, such as permanent colourful take milk product, lead to capacity as set decoration equipment corrosion perforation, consequently to current wash, restoring the passivation membrane. 4. Appearance cleanliness For stainless steel alloy, lower roughness in appearance, the more smooth appearance, foreign body harder weng, the lower the risk of each partial corrosion. Therefore, stainless steel should be used as probably finishing appearance. In addition, the appearance of stainless steel cleanliness is also very nervous, passivation after the final washing should be careful, because the residual acid promotes the cathode reaction, make the membrane layer, thus make stainless steel activation, violent reduce corrosion resistant function.
