Tin has excellent cooling and heat dissipation, coupled with its unique luster and easy processing characteristics It is widely used in household products You say it is suitable or not Besides, I have used a set of tin tea sets at home for several years There is no oxidation at all Not to mention the chemical reaction But I think you still have to be optimistic about the manufacturer Otherwise what you buy is not pure tin Then it is difficult to say I bought a round square tin If you like it, you can ask me.

The absence of a chemical reaction is relative, and the occurrence is absolute. Tin compounds are toxic (organotin is a biological pollution prevention and control product used on ships, specifically to sanitize oysters, barnacles and other organisms that will adhere to the hull), can not be made into tableware!

Tin is non-toxic, chemically similar to aluminum, and forms a dense protective film (tin oxide) in the air, so it is not easy to be oxidized and is relatively stable. But it cannot be used to contain acidic and alkaline substances because it is amphoteric substances; It can also not be used to contain chloride salts, chloride ions can penetrate the oxide film, thus forming a galvanic cell with impure tin alloy, accelerating the corrosion of tin. Tin elemental can react with halogen and sulfur element under heating conditions.
Tin at low or high temperatures (; 161), the crystal lattice will change, at low temperature, it will gradually turn into a loose powder like coal ash, if there is alcohol will be more likely to change; At high temperatures, it becomes brittle and crumbles when you knock it.
It's like that, is it still satisfying?

Tin is non-toxic, but it is said that many tin foils now contain excessive levels of lead, which can contaminate food.
Pewter is widely used and loved by people because of some of the excellent properties of tin itself. First of all, tin is harmless to the human body, tinplate is widely used in food packaging, and high-grade chocolate is packaged in tin foil, which is the best proof; Second, there are many unique features of tin living utensils, tin tea cans have good sealing, which can maintain the color and aroma of tea for a long time; Tin beer mugs are fast due to heat transfer? It doubles the taste of cold beer and is widely used.
Therefore, the tin ware enjoys the reputation of "holding water and sweet water, holding wine and mellow wine, storing tea flavor unchanged, and arranging flowers for a long time". Third, in addition to the beautiful metal color, tin also has good ductility and processing properties, with a variety of tin made of utensils and art jewelry can realistically reflect the creativity of every detail, so as to make the tin handicrafts lifelike, elegant and moving, these characteristics are any other metal handicrafts are unattainable.

Tin, a metallic element, a low-melting metallic element with a bluish white sheen, is divalent or tetravalent within the compound and is not oxidized by air. It is mainly found in the form of dioxide and various sulfides
Metal tin is soft, easy to bend, melting point, boiling point 2260.
The tin dioxide protective film is formed on the surface of tin in the air and stabilized, and the oxidation reaction is accelerated under heating. Tin reacts with halogen to form tin tetrahalide under heating; It can also react with sulfur; Tin is stable to water, can be slowly dissolved in dilute acid, and quickly dissolved in concentrated acid; Tin can be soluble in strong alkaline solutions; It will corrode in acidic solutions of salts such as ferric chloride and zinc chloride.
Tin is a silvery-white soft metal with a specific gravity of 232 and a low melting point
Tin is non-toxic, and people often plate it on the inner wall of copper pots to prevent the copper warm water from producing toxic patina. Toothpaste shells are also commonly used to make tin (toothpaste shells are made of two layers of tin ** and one layer of lead. In recent years, China has gradually replaced tin with aluminum to make toothpaste shells).
Solder, also containing tin, generally contains tin 61, some are lead and half tin, and some are composed of 90 lead, 6 tin and 4 antimony.
Tin is malleable at room temperature. Especially at 100 °C, it is very malleable and can be rolled into extremely thin tin foil. Usually, people use tin foil to package cigarettes and candies to prevent moisture (in recent years, China has gradually replaced tin foil with aluminum foil.
Aluminium foil is easy to distinguish from tin foil – tin foil is much brighter than aluminium foil). However, the ductility of tin is very poor, and it breaks when it is pulled and cannot be drawn into filaments. In fact, tin is only malleable at room temperature, and if the temperature drops below it, it will gradually turn into a loose powder like coal ash.
In particular, in the presence of -33 or an alcohol solution with red salt (SNCL4·2NH4Cl), the rate of this change is greatly accelerated. A well-ended tin pot will "automatically" turn into a pile of powder. This tin "disease" can also be transmitted to other "healthy" tin ware, which is known as the "tin plague".
The cause of tin plague is due to the change of the crystal lattice of tin: at room temperature, tin is the crystal structure of a square crystal system, called white tin. When you bend a tin bar, you can often hear a clattering sound, which is because the white tin crystals of the square crystal system rub against each other when bending, making a sound.
Below, the white tin is transformed into an amorphous gray tin. As a result, the clumps of tin turned into a mass of powder. Tin is not only afraid of cold, but also of heat.
Above 161, white tin is transformed into orthorbic tin with a crystal structure of orthorhombic crystal system. Orthorphobicin is very brittle, it will break when knocked and has poor malleability, so it is called "brittle tin". White tin, gray tin, and brittle tin are the three allotropes of tin.

Tin will turn into powder at low temperatures, which is very special and different from other metals.
The chemical properties are relatively stable, do not react with hydrochloric acid, anti-oxidation, and are electroplated on the iron sheet to make canned food boxes and become tinplate.

Dear, I am glad to answer this question for you, tin is mainly used to make solder, tinplate, alloys, chemicals, etc. It is widely used in electronics, information, electrical appliances, chemical industry, metallurgy, building materials, machinery, food packaging, atomic energy and aerospace industry. Tin is mainly used in the chemical industry to produce tin compounds and chemicals.
The organic compounds of tin are mainly used as wood preservatives, pesticides, etc., and the inorganic compounds of tin are mainly used as catalysts, stabilizers, additives and emulsifiers in the ceramic industry.

Summary. Most of the tin in the electronics factory is metal tin, and some of the tin may be oxidized when the welding machine is welded, but this is all trace and does not harm the human body. Tin is an element that is beneficial to the human body, and the metal tin is not harmful to the human body, even in large doses, it is not harmful, and the oxide toxicity of tin is quite weak.
What kind of tin is used in the tin melting furnace of the electronics factory, and is it harmful to the human body?
Hello, I have seen your question and am sorting out the answer, please wait a while Is the smoke of handmade electronic wire soaked in tin poisonous.

Tin smoke is poisonous, pine perfume will have a certain adverse effect on the body, if a large amount of inhalation in the body for a long time, it will hinder blood circulation, and will also cause the white blood cells and platelet content in the blood will decrease, especially may suffer from lung diseases, and even let some organs slowly fail.
I'm pregnant, can I still do this kind of work?
Does smoke have pine perfume.
Yes. Smoke is the smoke produced by high temperatures of pine perfume.
If you're pregnant, it's better to change your desk.
Ok thanks.
You are welcome.

It refers to a multiplexing technology in which the carrier bandwidth is divided into a variety of sub-channels of different frequency bands, and each sub-channel can transmit a signal in parallel. FDM is commonly used in broadband networks where analog transmissions are made. In a communications system, the bandwidth provided by a channel is often much wider than the bandwidth required to transmit a signal. >>>More
When I was 25 years old, I went on a blind date with a doctor very handsome Blind date is to press the road, walk on the road and chat, ask me how many suites at home, how many cars, work, salary, parents' work, salary, ask me about my love experience, I honestly said that I have never been in love. I asked a lot of questions, and I said them all. During this time, I paid for 1 bottle of mineral water. >>>More
