鋁卷生產(chǎn)廠家:鋁卷涂料的施工方法

來源:http://www.guangshe.com.cn/ 發(fā)布時(shí)間:2024-05-21

  鋁卷涂料主要是防腐蝕,今天為大家重點(diǎn)介紹鋁卷涂料的施工方法。

Aluminum coil coating is mainly used for corrosion prevention. Today, we will focus on introducing the construction methods of aluminum coil coating

  刷涂:

Brushing:

  刷涂法是一種早期、簡單和傳統(tǒng)的手工涂布方法,操作方便、靈活,可以適用于任何形狀的物體,除干燥、流平性差的涂料外,還可以適用于各種涂料。刷涂法可使涂料滲透,滲透金屬表面的孔隙,增強(qiáng)涂膜與金屬的附著力。缺點(diǎn)是勞動(dòng)強(qiáng)度大,工作效率低,涂層外觀不好。

Brushing method is an early, simple, and traditional manual coating method that is easy to operate and flexible, and can be applied to any shape of object. In addition to dry and poorly leveling coatings, it can also be applied to various coatings. The brushing method can allow the coating to penetrate, penetrate the pores on the metal surface, and enhance the adhesion between the coating film and the metal. The disadvantages are high labor intensity, low work efficiency, and poor coating appearance.

  刮涂:

Scratching:

  刮涂是使用刮刀不能進(jìn)行汽車涂裝的方法,用于用戶黏度具有較高和固體物質(zhì)含量多的液態(tài)涂料的涂裝。刮涂作業(yè)涂膜的常見安全問題是導(dǎo)致開裂、脫落、翻卷等,其涂膜的厚度也很難實(shí)現(xiàn)均勻。

Scraping coating is a method that cannot be used for car painting with a scraper, used for the coating of liquid coatings with high viscosity and high solid content for users. The common safety issues with coating during scraping operations are cracking, peeling, and flipping, and the thickness of the coating is also difficult to achieve uniformity.

  浸涂:

Dip coating:

  浸涂也是作為一種中國傳統(tǒng)的涂裝技術(shù)方法。該方法可以將被涂物浸沒在盛有涂料的槽液中,隨即取出,讓多余的涂料滴落回槽液中,或采用各種機(jī)械設(shè)計(jì)方法將多余的涂料甩落。該法溶劑損失風(fēng)險(xiǎn)較大,容易發(fā)展造成環(huán)境空氣質(zhì)量污染,不適用于揮發(fā)性涂料,且涂膜的厚度不易均勻,一般主要用于社會(huì)結(jié)構(gòu)比較復(fù)雜的器材或工件。

Dip coating is also a traditional Chinese painting technique. This method can immerse the coated object in a tank containing paint, then remove it and let the excess paint drip back into the tank, or use various mechanical design methods to shake off the excess paint. This method has a high risk of solvent loss, which can easily lead to environmental air quality pollution. It is not suitable for volatile coatings, and the thickness of the coating is not easy to be uniform. It is generally used for equipment or workpieces with complex social structures.

  例如: 在化工廠,有些設(shè)備,如組合式換熱器,由于內(nèi)管不能噴涂,可以采用全浸涂法施工。浸鍍鋁鋼管主要用于石化爐管、各種換熱器管、分餾塔管等。

For example, in chemical plants, some equipment, such as combined heat exchangers, can be constructed using the full immersion coating method because the inner tubes cannot be sprayed. Galvanized aluminum steel pipes are mainly used for petrochemical furnace pipes, various heat exchanger pipes, fractionation tower pipes, etc.

  淋涂:

Spray coating:

  淋涂是將涂料從噴嘴噴淋至被涂物表面,涂料經(jīng)過自上而下的流淌將被涂物表面完全覆蓋后形成涂膜的涂裝工藝工程。此法所用設(shè)備簡單,比較容易實(shí)現(xiàn)機(jī)械化生產(chǎn),操作簡便、生產(chǎn)效率高,但涂膜不平整或覆蓋不完整。涂膜厚度不易均勻。淋涂比浸涂的溶劑消耗量大,也會(huì)產(chǎn)生污染問題。

Spray coating is a coating process that sprays paint from a nozzle onto the surface of the object to be coated, and the paint flows from top to bottom to completely cover the surface of the object to form a coating film. This method uses simple equipment, is relatively easy to achieve mechanized production, is easy to operate, and has high production efficiency, but the coating is uneven or incomplete. The coating thickness is not easily uniform. Spray coating consumes more solvent than immersion coating, which can also cause pollution problems.

  噴涂:

Spray coating:

  噴涂是利用數(shù)據(jù)壓縮空氣在噴槍嘴產(chǎn)生的負(fù)壓將涂料進(jìn)行容器中的涂料從涂料通過噴嘴噴出,并迅即進(jìn)入中國高速的壓縮空氣流,使涂料液一一氣相急劇發(fā)展擴(kuò)散,被分散為霧狀微粒射向被涂物,均勻涂布在表面。該法要求被噴涂的涂料具有黏度比較小。常在涂料中加入作為稀釋劑。噴涂法優(yōu)點(diǎn)是涂膜厚度分布均勻、外觀是否平整、生產(chǎn)工作效率高。

Spraying is the process of using compressed air from data to generate negative pressure at the nozzle of the spray gun, which sprays the coating out of the container through the nozzle and quickly enters the high-speed compressed air flow in China. This causes the coating liquid to rapidly develop and diffuse in the gas phase, and is dispersed into mist like particles that are sprayed onto the coated object, evenly spreading on the surface. This law requires the sprayed coating to have a relatively low viscosity. Often added as a diluent in coatings. The advantages of spraying method are uniform distribution of coating thickness, smooth appearance, and high production efficiency.
