金屬化學蝕刻機的發展簡史Brief history of the development of metal chemical etching machine

發布日期:2018-09-08 作者:www.tonertimes.com 點擊:

 近幾十年來,化學蝕刻機運用化學腐蝕作為一種高精密而科學的化學腐蝕加工技術,在金屬材料上被廣泛用於腐蝕多種種類的圖文及外形加工。特別是航天和航空工業,幾乎隨處都能夠見到使用化學蝕刻加工技術生產的產品應用到生活中。然而作為一種化學減薄切割加工技術,其曆史可以追溯到很長遠的年代。對化學蝕刻這一技術並未被中國很早記錄下來,主要原因是我國古代對科學技術不夠重視的原因,。而在其他西方國家卻記錄了很早以前就對化學蝕刻技術的應用。Z早的一次記錄是西方在公元前1世紀就有人在討論NaOH和AL2(SO4)3的用途,這肯定是有誇大之嫌。對金屬腐蝕的應用及發展必須具備兩個條件才是有意義的,一是金屬的普及應用,二是對應金屬的蝕刻液的調配。金屬的發現和應用擁有更長的曆史,在這方麵中國是比其他國家更長遠的,主要來源於古代煉金術士的手段,Z早被發現的是銅和合金材料,然後就是鐵的發現。。鋁是近幾百年才被發現,加以提煉才被運用到生活中,所以西方有人公元前1世紀就討論NaOH和AL2(SO4)3的用途是沒有依據的。

等離子刻蝕機

  金屬腐蝕主要由三方麵的發展而來:1.金屬的發現和冶煉技術的發展;2.對應金屬蝕刻液的調配。

  在目前的生活中的,腐蝕是很常見的,但在古代這種情況是不可能發生的,因為那個時代是有木材、石頭、及土組成的。直到古人們掌握了金屬提煉技術能夠把金屬從依附的材料中分離出來,才得到了金屬。有了金屬的發現,人們就開始想辦法去運用,這裏應用裏麵就涉及到了腐蝕,但是很多液體的都不能很快的去在金屬表麵加工處理,這就必需要有能夠與金屬產生腐蝕的物質酸。Z早的酸當屬有機酸之類的發現,比如從耐酸中提出的乳酸,從檸檬中提出的檸檬酸和醋酸等,這些酸中以醋酸的強度Z強。僅憑這些有機酸很難完整對金屬做出有效的腐蝕加工,後麵當無機酸被發現後,金屬化學腐蝕加工來唄應用發展。所以金屬的化學腐蝕加工要在無機酸的發信啊後麵,這也是由等離子刻蝕機防蝕刻的材料發現的早晚有關係。在歐洲,15世紀化學腐蝕加工就變得流行起來,當時主要用於盔甲和工藝品的腐蝕加工。再造記載的蝕刻液配方是鹽、活性炭和醋酸配置而成,防護主要與亞麻油塗料和石蠟做防蝕刻材料來實現保護層做圖像轉移

       In recent decades, chemical etching machine, which uses chemical etching as a high-precision and scientific chemical etching processing technology, has been widely used in the processing of various kinds of pictures and shapes on metal materials. Especially in aerospace and aviation industry, almost everywhere we can see the products produced by chemical etching technology applied to life. However, as a chemical thinning cutting technology, its history can be traced back to a very long time. The technology of chemical etching has not been recorded in China for a long time. The main reason is that ancient China did not pay enough attention to science and technology,. In other western countries, the application of chemical etching technology has been recorded for a long time. The earliest record is that the use of NaOH and Al2 (SO4) 3 was discussed in the West in the first century B.C., which is certainly exaggerated. There are two conditions for the application and development of metal corrosion, one is the popularization and application of metal, the other is the deployment of etching solution corresponding to metal. The discovery and application of metals have a longer history. In this respect, China has a longer history than other countries. It mainly comes from the means of ancient alchemists. The first discovered materials are copper and alloy, and then iron.. Aluminum has been discovered for hundreds of years and refined before being used in daily life. Therefore, there is no basis for people in the west to discuss the use of NaOH and Al2 (SO4) 3 in the first century B.C. 

   The development of metal corrosion is mainly from three aspects: 

  1. The discovery of metal and the development of smelting technology;

  2. The allocations of etching solution.

      In the present life, corrosion is very common, but in the ancient times, this kind of situation is impossible, because that time was composed of wood, stone, and soil. Until the ancients mastered the metal refining technology to separate the metal from the attached materials, they got the metal. With the discovery of metal, people began to think of ways to use it. Corrosion is involved in the application here, but many liquids can not be processed on the metal surface quickly, which requires the material acid that can produce corrosion with metal. The earliest acids are organic acids, such as lactic acid from acid resistance, citric acid and acetic acid from lemon, among which the strength of acetic acid is the strongest. Only these organic acids are difficult to make effective corrosion processing for metals. Later, when inorganic acids are found, metal chemical corrosion processing will be applied and developed. Therefore, the chemical etching of metals should be done after the letter of inorganic acid, which is also related to the early and late discovery of anti-corrosion materials of plasma etching machine. In Europe, chemical etching became popular in the 15th century, when it was mainly used for the etching of armor and crafts. The etching solution formula of the reconstructed record is made of salt, activated carbon and acetic acid. The protection is mainly made of linseed oil coating and paraffin as anti etching materials to realize image transfer of the protective layer.
