彩鋼瓦常用的烘干處理與打磨方式是什么

來源:http://www.ebassfish.com/ 日期:2021-08-06 發布人:jiangucaigang
彩鋼瓦含有的水分會使它的抗壓能力降低,出現的結果就是我們所看到的變形,所以說彩鋼瓦的烘干處理是制作工程中非常重要的一個步驟,那么常用的烘干處理與打磨方式是什么:
The moisture contained in the color steel tile will reduce its compressive capacity, and the result is the deformation we see. Therefore, the drying treatment of the color steel tile is a very important step in the manufacturing project. What are the common drying treatment and grinding methods:
常用的烘干方法是用自己建的土窯對彩鋼瓦的原材料進行烘干處理,減少對于成品烘干的成本。
The common drying method is to use the earth kiln built by ourselves to dry the raw materials of color steel tiles, so as to reduce the drying cost of finished products.
因為土窯是采用人工燒炕的方式加熱,溫度不均勻,經常會出現一部分已經烤干了,而有的還存在許多水分,也沒有控制好開裂和變形的幾率。所以除了要進行一次的蒸汽烘干以外,在加工之前還要進行二次的微波烘干,是的水分可以從里往外均衡蒸發。
Because the earth kiln is heated by manually burning Kang, the temperature is uneven, and often some have been dried, while some still have a lot of moisture, and the probability of cracking and deformation is not well controlled. Therefore, in addition to the primary steam drying, the secondary microwave drying should be carried out before processing. Yes, the water can evaporate evenly from inside to outside.
彩鋼瓦在施工的時候,需要對彩鋼瓦進行打磨,其目的是保持它的美觀性,保證施工的安 全性。對于它的打磨方式分為干打磨、濕打磨和機械打磨三種:
During the construction of color steel tile, it is necessary to polish the color steel tile in order to maintain its beauty and ensure the safety of construction. Its grinding methods are divided into dry grinding, wet grinding and mechanical grinding:
1、機械打磨
1. Mechanical grinding
彩鋼瓦大面積施工時,為了提高工作效率,可采用機械打磨方法,如電動打磨機,有圓盤式和振動式。
During large-area construction of colored steel tiles, in order to improve work efficiency, mechanical grinding methods can be adopted, such as electric grinder, including disc type and vibration type.
2、干打磨
2. Dry grinding
采用砂紙進行打磨,適用于硬而脆的漆種的打磨,這種對彩鋼瓦進行打磨的缺點是操作過程中將產生很多粉塵,影響環境衛生。
Sandpaper is used for grinding, which is applicable to the grinding of hard and brittle paint. The disadvantage of this kind of grinding of color steel tile is that a lot of dust will be generated during operation, affecting environmental sanitation.
3、濕打磨
3. Wet grinding
用水砂紙蘸水或肥皂水打磨彩鋼瓦,水磨能減少磨痕,提高涂層的平滑度,并且省砂紙、省力,但水磨后應注意噴涂下層油漆時,一是要等水磨層完全干透后才能涂下層油漆,否則漆層很容易泛白,另外吸水性很強的底材也不宜水磨。
Polish the colored steel tile with sand paper dipped in water or soapy water. Water grinding can reduce grinding marks, improve the smoothness of the coating, and save sand paper and labor. However, when spraying the lower layer of paint after water grinding, first, the lower layer of paint can be painted only after the water grinding layer is completely dry, otherwise the paint layer is easy to whiten, and the substrate with strong water absorption is not suitable for water grinding.
