鋁粒在使用中起到什么作用?

來源:http://www.menguosenlin.cn/ 發(fā)布時間:2018-12-05

鋁為什么是有色金屬?狹義的有色金屬又稱非鐵金屬,是鐵、錳、鉻以外的所有金屬的統(tǒng)稱;廣義的有色金屬還包括有色合金(以一種有色金屬為基體(通常大于50%),加入一種或幾種其他元素而構(gòu)成的合金)。
Why is aluminium a non-ferrous metal? In the narrow sense, non-ferrous metals are also called non-ferrous metals, which are the collective name of all metals except iron, manganese and chromium. In the broad sense, non-ferrous metals also include non-ferrous alloys (alloys based on a non-ferrous metal (usually more than 50%) with one or several other elements added).
鋁的密度小,只有2.7g/cm,表面存在致密的AlO薄膜,阻止內(nèi)部的鋁進(jìn)行反應(yīng),不易被氧化。它是飛機(jī)常用的材料,現(xiàn)代飛機(jī)有70%是鋁和鋁合金制造的,所以叫會飛的金屬。
The density of aluminium is small, only 2.7g/cm. There is a dense AlO film on the surface, which prevents the internal aluminium from reacting and is not easy to be oxidized. It is a common material for aircraft. 70% of modern aircraft are made of aluminium and aluminium alloy, so it is called flying metal.
鋁型材如果不經(jīng)表面處理,外觀不美觀,而且在潮濕空氣中容易被腐蝕,這樣很難達(dá)到建筑材料中對鋁型材高裝飾性和強(qiáng)耐候性的要求,為了提高裝飾效果、增強(qiáng)抗腐蝕性及延長使用壽命,鋁型材一般都要進(jìn)行表面處理。
Without surface treatment, the appearance of aluminium profiles is not beautiful, and it is easy to be corroded in humid air, so it is difficult to meet the requirements of high decoration and strong weatherability of aluminium profiles in building materials. In order to improve decoration effect, enhance corrosion resistance and prolong service life, aluminium profiles generally need surface treatment.
鋁粒又名鋁丸、鋁砂,鋁粒采用含99%鋁的鋁錠反復(fù)拉絲、裁切、研磨等工藝精制而成。外觀光亮、圓柱狀、應(yīng)用于鋁、鋅或薄壁工件的表面。

 鋁卷生產(chǎn)廠家
Aluminum granules are also known as aluminium balls and aluminium sand. Aluminum granules are refined by repeated drawing, cutting and grinding of aluminium ingots containing 99% aluminium. Bright appearance, cylindrical, applied to the surface of aluminium, zinc or thin-walled workpieces.
廣泛應(yīng)用于鋁鑄件及銅、鋅鑄件的表面精加工處理,各種金屬表面的噴沙打磨,鑄造工件的除毛邊、毛刺,刃物表面、鑄造制品表面的噴沙打磨等??墒鼓漠a(chǎn)品平整、光潔、發(fā)亮、達(dá)到增白的效果。
It is widely used in surface finishing of aluminium castings, copper and zinc castings, sandblasting grinding of various metal surfaces, deburring and burring of casting workpieces, sandblasting grinding of blade surfaces and surface of casting products, etc. It can make your products smooth, smooth, shiny and achieve whitening effect.
同時鋁粒又可與不銹鋼砂、不銹鋼丸參合使用,達(dá)到對工件表面更白更亮的效果。鋁粒,LED半導(dǎo)體 ,蒸渡 用的比較多,對純度要求也比較高。
At the same time, aluminium particles can be used in combination with stainless steel sand and stainless steel pellets to achieve whiter and brighter surface of the workpiece. Aluminum particles, LED semiconductors, steaming is used more, the purity requirements are relatively high.

What is the use of aluminium particles? It can be widely used to finish the surface of aluminium castings and zinc and copper castings, sandblasting and polishing various metal surfaces, deburring and burring of casting parts, or sandblasting and polishing of casting products and blade surfaces. Aluminum particles can make your metal products flat, smooth, shiny and achieve whitening effect. At the same time, aluminium particles can be used in combination with stainless steel sand and stainless steel pellets to achieve whiter and brighter surface of the workpiece. In the LED semiconductor, steaming is used more, the purity requirements are also relatively high.
