Chromium plating is a relatively late development process. Although chromium plating from trivalent bath had been done as early as 1854, it was invented in 1856.
However, it was not until the 1920s that the chromium plating process was widely used abroad.
Chromium plating technology was introduced to China late, and the introduction and application of chromium plating knowledge were mostly recorded in the early 1930s. Introduction and Naming of Chromium in China
65438+ began in the 1960s.
Although the word "chromium" was included in the ancient dictionary of China, it didn't mean metallic chromium. "Harmony" has two meanings in ancient dictionaries: a, picking up hair; Ancient weapons
Name (similar to hook). The word "Cr" is used to represent the element Cr, which is given a new meaning by using ready-made Chinese characters.
The symbol of chemical element R has been included in Introduction to Wu Ge published by 1865, but there is no Chinese translation and English name. In the future, I learned that scholars are foreignizing translation.
When I was studying books, I tried to use the following Chinese characters to represent Cr.
1870 He Ming of Guangzhou was named Ji in the primary stage of chemistry; 1873 He Ming's name is Li in the Chemistry Guide of Beijing Museum; At 19 10, Guangzhou's Guangdong proposal.
Kama newspaper was named "Gromo"
1972, I met Xu Shou, a pioneer in chemistry, who named it "chromium" in the original edition of Chemistry, which was accepted by the scientific and technological circles at that time. But it is represented by cymbals.
Chromium was also used in southern China for some time. Until the beginning of this century, various newspapers and periodicals published in Guangzhou, such as the ninth issue of Guangzhou Industrial News, still used the word "Liu".
Issue (18 10) has an article "The Method of Curing", and the so-called chromium oxide is chromium oxide. The tenth issue also published the article "Electroplating Methods" (1908), which was called "Electroplating".
It's chrome plated.
In modern Chinese, the ancient meaning of the word chrome has disappeared. In Xinhua Dictionary and Modern Chinese Dictionary. Chromium is specially used to represent the metal element Cr, and the phonetic notation is ge.
In ancient Chinese, chrome has two pronunciations: Luo and Ge. According to Xu Shou's naming principle of chemical elements and the provisions of modern dictionaries, chromium should be pronounced ge. interesting
It is in the electroplating industry that most people pronounce chromium plating as Luo (homonym)
Early chromium plating literature
Because chromium plating is a post-process, there is no introduction of chromium plating in China's early electroplating books, such as gold electroplating and gold plating. Published in the late19th century.
There is no record of chrome plating in the books of "Western Learning".
China's earliest introduction to chromium plating was Industrial News published in Guangzhou. In the tenth issue of the newspaper, there was an article "Electroplating Chromium Plating", which was published on May 12, Guangxu 34 (
1908 June 10). Because chromium plating is still in the experimental stage abroad, it is impossible to apply chromium plating in China before 1908.
When chrome plating was widely used abroad in the 1920s, many imported products were chrome plated, and this new process was only known in China. Foreign goods, such as watches and clocks, were imported from Guangzhou and Shanghai at that time.
Watch, water tank, lampshade, "chrome plated". In particular, imported flashlights, including simplified body and reflector, "also use chrome plating instead of nickel plating", "chrome plating surface is hard, smooth and fresh.
Tomorrow, silver will be brighter than nickel plating, which will directly threaten the flashlight industry in China. In order to compete with foreign goods, domestic products have to catch up, forcing me to cross the electroplating industry.
Develop this new process. (The text in brackets is the newspaper statement at that time)
In 1930s, chromium plating has occupied an important position in electroplating industry in China, but the theoretical knowledge about chromium plating is very poor, and only a few articles involve chromium plating.
Cities that used chromium plating in the early days
193 1 year, the North China Electroplating Company founded by British businessmen in Tianjin included chromium plating, which was the earliest application record of chromium plating in China. The application of chromium plating in Shanghai is also open
Since the early 1930s, according to the meeting of electroplating predecessors in Shanghai, electroplating plants in Shanghai have applied chromium plating in 193 1. Among them, such as Zhongnan electroplating factory and foreign general electroplating factory.
Roche electroplating factory, etc. , also belongs to the earliest electroplating factory. Most of the chromium plating equipment in these factories comes from abroad.
