Healthy titanium home furnishing flies into the homes of ordinary people
"The world of titanium is really wonderful", Cao Chunxiao, academician of the Chinese Academy of Sciences, said this sentence in several reports. In the past, people thought that titanium metal was a rare metal, but it is not. It ranks seventh in the earth's metal content, which is higher than common metals such as copper and zinc. In various fields of sea, land and air, titanium metal also plays a brilliant role. In marine engineering, the strong corrosion resistance of titanium makes it look like new in seawater for a hundred years without rust; in aerospace industry, titanium can be made into the "skeleton" and "coat" of fighter planes and spacecraft, which are light, high-strength and anti-corrosion. Invasion of high temperature; In the chemical and pharmaceutical industry, titanium is stable, corrosion-resistant and non-toxic, making it a necessary material for many equipment. The most well-known is the application of titanium metal in medical surgery. In the operation of bone healing, if titanium metal is used instead of conventional stainless steel implants, the titanium metal sheet can be attached to the joint to assist growth without taking it out, and it will not increase the pain of the patient in the later stage of healing. Therefore, titanium is also praised as "the most Biophilic metals".
Another widely used titanium metal in the era of titanium—pure titanium household products, as the darling of the new era, has quietly come into our lives. Take our commonly used electric kettles and thermos cups as examples. Sensitive people can drink hot boiled tea in stainless steel containers with an iron smell, because the iron ions in the container materials dissolve into the water at high temperatures. The main components of stainless steel are iron, nickel, chromium, and manganese. The heavy metals in them will also dissolve into the water, and the deposition of heavy metals in the human body will cause lesions, but titanium containers do not have these problems. Taking bamboo and wood chopsticks as an example, the so-called disease enters from the mouth. After repeated use, the worn-out chopsticks will hide food residues. Over time, aflatoxin will be produced. Aflatoxin is classified as a Class 1 carcinogen by the World Health Organization, and its toxicity is 10 times that of the highly toxic substance potassium cyanide and 68 times that of arsenic. Titanium metal is healthy, non-toxic, and has natural antibacterial properties, which can always protect the health of the family, which is incomparable to ordinary metals.
Titanium household products do not dissolve the carcinogenic heavy metals nickel, chromium, and manganese in high-temperature, acidic or alkaline food environment, and have the characteristics of never rusting, natural antibacterial, biophilicity, long-lasting freshness, and durability. It is welcomed by consumers, but its price, which is no less than that of high-end consumer goods, also discourages many consumers. People can't help wondering, what is the reason for the high price of titanium household products? There are mainly the following reasons.
The cost of materials is expensive
Due to the mature technology of some commonly used materials for household items, the cost has been controlled and optimized, and the price has been fully accepted by the market. As for titanium metal, due to the high production cost of simple titanium and the low yield rate, the price of Grade 6 titanium sheet with the same size is more than 10 times that of stainless steel 201 or 304. Considering that the specific gravity of titanium is much lighter than that of stainless steel, the material used The cost is also 5-7 times higher.
difficult to process
Titanium material itself is a typical difficult-to-machine material, which has extremely high requirements on equipment, molds, cutting tools, tooling, and processing technology. But once processed, he can be said to be "indestructible". Difficulties in processing titanium profiles are mainly manifested in the following aspects:
1. Titanium is difficult to cut. The deformation coefficient of titanium alloy is less than or equal to 1, and the contact surface with the rake face is small during cutting, so that the pressure and local temperature in the contact area are high, and the tool wears quickly. At the same time, titanium will produce severe work hardening during processing.
2. Titanium is difficult to weld. During welding, titanium in a high-temperature state easily reacts with hydrogen and oxygen in the air, resulting in "hydrogen embrittlement", which leads to easy cracking of the product and low yield.
3. Titanium is difficult to draw and process. The drawing processing of titanium has high requirements on the material, specification tolerance and tensile performance of Grade 5 titanium plate, and even higher requirements on mold fit, otherwise the product is easy to wrinkle or break. At the same time, the speed of the equipment and the lubricating oil used are also very particular. How to heat-treat the titanium material that has been stretched many times is even more difficult. These problems will directly lead to a decrease in the yield.
4. The surface treatment of titanium is difficult. Because the five elements of titanium polishing (man, machine, material, method, and ring) are different from the process requirements of conventional materials, the processing cost of titanium surface treatment is several times, or even more than ten times, that of other materials.
High development cost
Due to the incomplete processing data of titanium civil products, the development cycle is longer, and the mold needs to be modified and debugged repeatedly, and there is a possibility of scrapping and unsuccessful development. For example: the normal cost of a set of molds for pure titanium electric kettles is usually 300,000 to 400,000 yuan. Due to the limited order quantity of pure titanium electric kettles, the production quantity is far less than that of stainless steel products, so the average cost of molds is particularly expensive. .
The cost of new product promotion is high
Since there are very few researches and reports on titanium and titanium products by authoritative academic institutions or mainstream media, many end consumers know little about titanium as a material, and it is even more difficult to know the various practical benefits of using titanium household products.
Fortunately, thanks to the development and long-term unremitting promotion of domestic titanium product processing enterprises and titanium product brand enterprises in their respective fields, one technical difficulty after another has been overcome in the processing of titanium products, and the development of titanium products has been opened one after another. In the market, more and more people dare to be the first to eat crabs, there are more and more beautiful and practical titanium household products, and more and more well-known household enterprises are involved.
Regarding the titanium materials used in processing, titanium industry associations, enterprises and individuals are working hard to formulate and implement relevant standards, so that titanium-related enterprises can rely on them and consumers can be more confident. The drawing, welding and polishing processes of titanium are also being further improved and perfected, and some special processing equipment and auxiliary materials are also coming into the market one after another. For example: when stretching, the choice of lubricating oil is good, and the yield is higher; the appearance of special welding equipment makes the weld seam of titanium more perfect; the new titanium throwing process, equipment and auxiliary materials make the surface treatment of titanium easier. Various improvements and changes make good titanium products better presented in the eyes of the public.
The civilian use of titanium metal is a concrete manifestation of people's requirements for improving the quality of life, and it is an entry point to understand another healthy life. In the process of developing and promoting titanium products, Zhongshan Heshun Titanium Industry is not eager to expand the market, but is more willing to refine and upgrade products, identify product positioning, and make word-of-mouth hits. As the saying goes: Only by focusing on things can we go further. It is not the products with higher prices that can be called "luxury" products. The greatest luxury is the things that can really accompany people and help people get healthy.
Because they know the advantages of titanium household products and feel the development prospects of titanium household products, well-known enterprises that traditionally produce stainless steel, glass and plastic household products are also constantly involved, and they are actively trying to produce and promote titanium household products. There will be more people know titanium, be familiar with titanium and enjoy titanium. As the demand for titanium products rises, the various costs of titanium products will also decrease. I believe that in the near future, healthy titanium household products will become a household name, adding a solid guarantee for the happiness and healthy life of more people.
