通常，我們看到的彩鋼板的變形主要是由于彩鋼板中的水分導(dǎo)致其抗壓能力下降。因此，彩鋼板的干燥處理是制造工程中的關(guān)鍵工序。常見的烘干處理和打磨方法是什么?

Generally, the deformation of color steel plate we see is mainly due to the decrease of its compressive capacity caused by the moisture in the color steel plate. Therefore, the drying treatment of color steel plate is a key process in manufacturing engineering. What are the common drying and grinding methods?

彩鋼板干燥處理方法：

Drying method of color steel plate:

常用的干燥方法是利用自建土窯對彩鋼板的原料進行干燥，以降低產(chǎn)品干燥成本。由于土窯采用人工燒炕加熱，溫度不均勻，經(jīng)常表現(xiàn)為有的已經(jīng)干燥，有的仍有大量水分，開裂變形的概率沒有得到很好的控制。

The common drying method is to use self built earth kiln to dry the raw materials of color steel plate, so as to reduce the drying cost of products. Because the earth kiln adopts artificial kang heating, the temperature is uneven, which often shows that some have been dried, some still have a lot of water, and the probability of cracking and deformation has not been well controlled.

因此，除了初的蒸汽干燥外，加工前還應(yīng)進行第二次微波干燥。是的，水可以從內(nèi)向外均勻地蒸騰。彩鋼瓦彩鋼瓦施工時需打磨。其用意是堅持其美觀，確保施工。其打磨方法分為干磨、濕磨和機械打磨。

Therefore, in addition to the initial steam drying, the second microwave drying should be carried out before processing. Yes, water can transpiration evenly from the inside out. Colored steel tiles shall be polished during construction. Its purpose is to adhere to its beauty and ensure construction safety. The grinding methods are divided into dry grinding, wet grinding and mechanical grinding.

彩鋼板打磨方法：

Grinding method of color steel plate:

在大面積機械打磨彩鋼板施工中，為提高工作效率，可選用機械打磨方式，如電動打磨機，包括圓盤式和擺動式。干磨選用砂紙，適用于硬脆油漆的磨削。這種磨削彩鋼板的缺陷是在操作過程中會產(chǎn)生大量粉塵，影響環(huán)境衛(wèi)生。

In the construction of large-area mechanical grinding of color steel plate, in order to improve work efficiency, mechanical grinding methods can be selected, such as electric grinding machine, including disc type and swing type. Sand paper is used for dry grinding, which is suitable for grinding hard and brittle paint. The defect of this kind of grinding color steel plate is that a large amount of dust will be generated in the operation process, which will affect environmental sanitation.

濕磨使用砂紙蘸水或肥皂水打磨彩鋼瓷磚。水研磨可以減少磨損痕跡，提高涂層的平滑度，節(jié)省砂紙和勞動力。但水磨后噴涂底漆時，需要待水磨層干燥后才可施涂底漆，否則漆層很簡單，呈白色，其他吸水性強的基材不宜水磨。

Wet grinding use sandpaper dipped in water or soapy water to polish color steel tiles. Water grinding can reduce wear marks, improve the smoothness of the coating, and save sandpaper and labor. However, when spraying primer after water grinding, the primer can be applied only after the water grinding layer is dry, otherwise the paint layer is very simple and white, and other substrates with strong water absorption should not be water grinding.

干燥主要采用初次的蒸汽干燥和二次微波干燥，打磨分為干磨、濕磨和機械打磨，現(xiàn)在隨著科技的發(fā)展，以及濟南彩鋼廠家對效率的要求，更多采用機械打磨。

Primary steam drying and secondary microwave drying are mainly used for drying. Grinding is divided into dry grinding, wet grinding and mechanical grinding. Now, with the development of science and technology and the efficiency requirements of Jinan color steel manufacturers, mechanical grinding is more used.
