Galvanized strip steel is made of high-quality steel. It is made of galvanized strip steel with many excellent properties, so that the product has been used by significant businesses since its launch. For example, the kitchen utensils in our lives are made of galvanized strip steel. No matter any material or equipment, there will be various problems without maintenance. The editor will summarize a few maintenance methods for galvanized steel strip for you, and hope that it will be helpful to your use.
First, during our daily use, avoid storing in a humid environment, otherwise it will cause oxidation on the surface of the galvanized steel strip, affecting its life, so as to extend the life of the product and ensure the quality of the product. Second, the equipment processed from galvanized steel strip is wiped after use, so as to ensure the beauty of the product and prolong its life. This is a matter of habit. I hope everyone can keep this in mind.
Third, many auto parts are also made of galvanized strip steel. We should pay more attention to wiping when the rainy season comes. The acidic substances contained in the rain will cause corrosion for a long time. Although our products have excellent corrosion resistance, In order to ensure a better and more prolonged use, please be careful when wiping and cleaning.
The dirt on the surface of the substrate is mainly oxide layer and grease. The method of removing fat is primarily to use the characteristics of lubricant to be soluble in organic solvents and capable of saponification. Alkaline solution soaks and sprays to remove oil stains on the metal surface. This method is called chemical cleaning. At present, the most economical chemical cleaning agent is alkaline agent, and the most effective cleaning process is spray cleaning. This is because when the alkali lotion is used for soaking, the mass fraction of the alkali agent is generally 3%-8%, and when the spray method is used for cleaning, the mass fraction of the alkali lotion is about 1%.
The storage of galvanized steel strip is relatively simple and convenient. It does not need to be strict, just pay attention to the humidity of the storage environment. Like other galvanized steel strip products, you need to pay attention to the air humidity in the storage environment. In addition, you also need to ventilate the warehouse regularly to keep it dry. Regular inspections should be performed on the galvanized steel strip. The phenomenon of rust, this is because it has been oxidized in contact with air, and it can be used commonly.
Spare parts for the production of galvanized strip are classified according to the characteristics of the spare parts: Common spare parts refer to features that are frequently used, have a significant loss of equipment shutdown, and are relatively cheap for a single machine, and need to maintain a certain amount of reserve continually, such as large consumption parts and shutdown equipment. Insurance reserve parts, etc. Unusual spare parts refer to spare details with low frequency of use and low cost of downtime.
The alkaline washing solution with wetting agent relies on the wetting and spreading ability of the metal surface of the substrate to remove the grease and make it peel off the surface of the metal substrate, and then it is surrounded by the micelles formed by the surfactant molecules in the solution without re-depositing on it. On the surface of the metal substrate, the cleaning effect is enhanced. The flocculant can accelerate the saponified oil in the wastewater treatment system to facilitate the treatment of the flocculant.
Mainly rely on the chemical action of alkali to remove grease and slight rust on the metal surface. Suitable for ferrous metals and metals insoluble in lye, such as steel, cast iron, nickel, etc. Alkaline washing solution has the ability to dissolve, saponify and decompose water, and relies on the saponification of animal and vegetable oils to dissolve and remove them. The formed soap solution can solubilize oils that are not easily saponified in water and leave the metal surface. In addition, some alkaline washing solutions also add wetting agents and flocculants and other substances.
