How to prevent rust and what are the methods to prevent rust

How to prevent rust ?

Fruit rust is easy to occur in apples, jujubes, pears and other fruits, which seriously pollutes the face of the fruit, makes the original bright color and bright fruit become gray and dark, and reduces the grade of the fruit. The selection of fruit tree varieties, the influence of high temperature and arid climate, and the improper use of organophosphorus pesticides are important causes of fruit rust.

Precautionary measures: 1. Choose disease-resistant varieties. After years of observation, among the many apple varieties, the Marshal apple has effective and strong resistance to fruit rust, and the Fuji series of Shouhong Fuji and Liquan Short-to-Fu, Miyazaki, Huimin and other short-branched Fuji also have strong resistance to fruit rust, and among the yellow varieties, you can choose the more resistant to fruit rust Wang Lin, Australian apples and other varieties.

2. Spraying prevention and control. Before the budding of the fruit tree, when the bud germinates to the size of the thumb of the young fruit, spray the tree general to prevent the invasion of germs. Pay attention to the spraying prevention of fruit trees after flowering, which is the key to the prevention and control of apple rust.

3. Humidification and drought resistance. From mid-May to late June every year, in case of continuous high temperature and arid climate, humidification and drought resistance should be carried out in a timely manner, and the orchard with irrigation conditions should be irrigated with the whole garden, and the water spray can be carried out on each fruit tree in the morning and evening without irrigation conditions, so as to increase the humidity of the orchard, and the new high-fat film is fully sprayed after spraying, and the film-forming substances are used to protect the soil and the tree's own nutrient water is not easy to evaporate, and at the same time prevent the external climate and pesticides from invading the fruit, and reduce the disease rate of fruit rust.

4. Organophosphorus pesticides are prohibited at the young fruit stage. In the young fruit stage of apples from May to June, it is strictly forbidden to use organophosphorus pesticides for pest control to avoid the increase in the rate of fruit rust caused by human factors.

5. Pharmacy**. In early summer, the main trunk of the diseased tree was circumcised, and Kao No. 2 was applied to the circumcision to activate the antibodies of the fruit tree and inhibit the replication of the virus.

6. Fruit bagging. Within 40-50 days after flowering, the fruit is bagged throughout the garden. On the one hand, this measure can improve the appearance quality of the fruit, reduce the pollution of pesticides and harmful dusts to the fruit, and on the other hand, it can effectively prevent the occurrence of fruit rust.

Summary. Hello dear. There are 6 ways to prevent rust, including: coating rust prevention, environmental rust prevention, design rust prevention, corrosion inhibitor rust prevention, electroplating corrosion prevention, cleaning rust prevention, etc.

Hello dear. There are 6 ways to prevent rust, including: coating rust prevention, environmental rust prevention, design rust prevention of simple core or sock rust, corrosion inhibitor rust prevention, excavation plating corrosion prevention, cleaning rust prevention, etc.

1. Coating rust prevention can reduce the generation of rust with coatings (such as paint), and the coating can isolate the impact of the environment on iron. For example, large iron structures with closed boxes (such as ships and automobiles) often inject wax-containing anti-rust oil into the structure. Reinforced concrete is the use of concrete to wrap the rebar in an alkaline environment.

2. Environmental anti-rust control environment can achieve the effect of anti-rust, such as controlling the humidity below a certain value, which can reduce or avoid the formation of rust. 3. Design anti-rust Proper design also helps to prevent rust, such as avoiding the iron parts being exposed to water screaming, or wrapping the iron parts with a metal with strong corrosion resistance. 4. The use of anti-rust anti-corrosion agents, such as gas or volatile anti-corrosion agents, can be used to prevent rust in confined spaces.

5. Electroplating anti-rust plating is the process of plating a thin layer of other metals or alloys on some metal surfaces with the principle of electrolysis, which is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts, so as to prevent metal oxidation. 6. Cleaning and anti-rust cleaning and anti-rust method refers to frequently cleaning the surface of the iron ridge to prevent oxidation of iron parts and reduce the formation of rust.

1) Surface cleaning: The appropriate method must be selected according to the nature of the surface of the rust to be prevented and the conditions at the time. Solvent cleaning, chemical treatment cleaning and mechanical cleaning are commonly used.

2) After the surface is dry and cleaned, it can be dried with filtered dry compressed air, or dried with a dryer of 120 170, or wiped with clean gauze.

Method of applying anti-rust oil:

1) Soaking method: Some small items are soaked in anti-rust grease and a layer of anti-rust grease is adhered to their surface. The oil film thickness can be achieved by controlling the temperature or viscosity of the anti-rust grease.

2) The brushing method is used for outdoor construction equipment or products with special shapes that are not suitable for soaking or spraying, and it is necessary to pay attention not to accumulate when brushing, but also to prevent leakage.

3) Spray method: Some large rust prevention materials can not be oiled by immersion method, and are generally sprayed in an air clean place with filtered compressed air of about pressure. The spray method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil, but perfect fire prevention and labor protection measures must be adopted.

What are the main factors that affect metal corrosion?

Metal corrosion is caused by a variety of internal and external factors, which can be summarized as follows:

the chemical composition and structure of the metal material itself;

metal surface finish (oxygen concentration difference, battery corrosion);

the composition and pH of the solution in contact with the metal surface;

ambient temperature and humidity;

A variety of environmental media that come into contact with metal surfaces.

Why does sweaty hands cause metal rust?

Rock Demolition Human sweat is a colorless, transparent or yellowish liquid with a salty taste and weak acidity, and its pH value is 5 6. In addition to containing sodium, potassium, calcium, and magnesium salts, it also contains a small amount of organic acids such as urea, lactic acid, and citric acid. When sweat comes into contact with metal, a sweat film will be formed on the surface of the metal, and the sweat film will cause electrochemical anti-slip effect on the metal and corrode the metal.

It is inevitable for people to sweat, to prevent rust caused by hand sweat, production personnel should wear gloves, finger covers, or use special tools to pick up parts, and do not touch the product with their hands casually.

For the time being, I thought of this, and I replied.

Summary. Dear, hello, I have found out for you what are the methods of rust prevention 1, food rust prevention and rust removal method 1, with cut shallots, freshly cut off potato slices or radish peel dipped in a little salt, grinding the rusty place vigorously, can easily remove the rust 2, as for rust prevention, use cut ginger to smear the iron pot or kitchen knife, or put the leftover tea residue in gauze to wipe the iron pot, soak the cleaned iron utensils into the thick rice washing water to dry, can effectively prevent rust 2, the seasoning is also rusty 1, vinegar is the most commonly used rust removal item, the iron pot is rusty, Just pour some vinegar into the pot, add water to boil, and brush while burning, and the rust can be quickly removed. If the copper pot is rusty, scrub it with vinegar as well, and the patina will disappear quickly.

If the aluminum products are rusty, it is enough to soak them in vinegar water for a while.2. The coarse particles of salt are also ideal for rust removal. If the pot is rusty, put salt in the pot to fry, and wait for the salt to turn yellow after turning off the heat and wipe the pot, soon to remove the rust 3, the oil has the function of rust prevention, in the past in the countryside there will be a piece of pig skin on the edge of the stove, after washing the pot to wipe it, it can play a role in rust prevention, and we can now smear the kitchenware with a thin layer of cooking oil to prevent rust 3, tin foil rust removal method is used to wrap cigarettes, chewing gum, and also used to bake popcorn Tin foil do not throw away, knead it into a ball, dip it in water, and wipe the rusty place back and forth, It doesn't take long for items to sparkle.

There are those ways to prevent rust.

1. Fruits generally contain fruit acids, such as citric acid and malic acid.

2. The salts of these fruit acids can have a certain anti-rust effect, but the effect is very general.

3. Citric acid and malic acid are both weak acids, which can be used to remove rust, and it is okay for light rust, but strong acid is still used for deep rust.
