電纜橋架噴塑工藝也就是我們常講的靜電粉末噴涂,它是利用靜電發(fā)生器使塑料粉末帶電,吸附在鐵板表面,然后經(jīng)過高溫風(fēng)機(jī)180～220℃的烘烤,使粉末熔化黏附在金屬表面。下面來濟(jì)南橋架廠家講講橋架靜電噴涂工藝流程。

The cable tray spraying process is also known as electrostatic powder spraying. It uses an electrostatic generator to make the plastic powder charged, adsorbed on the surface of the iron plate, and then baked at 180-220 ℃ by a high-temperature fan to make the powder melt and adhere to the metal surface. Next, let's talk about the electrostatic spraying process of bridge from Jinan Bridge manufacturer.

1、前處理：

1. Pretreatment:

意圖：去除工件表面的油污、灰塵和銹跡，在工件表面形成一層既防腐蝕又能增加噴涂層附著力的“磷化層”。

Intention: remove the oil, dust and rust on the surface of the workpiece, and form a "phosphating layer" on the surface of the workpiece, which can not only prevent corrosion, but also increase the adhesion of the spraying layer.

主要工藝流程：脫脂、除銹、磷化、鈍化。預(yù)處理后的工件不僅表面無油污、銹跡和灰塵，而且在原有銀白色光澤的表面上形成一層均勻粗糙的不易生銹的灰色磷化膜，可起到防銹作用。并添加一個(gè)噴涂層。

Main process flow: degreasing, derusting, phosphating and passivation. The pretreated workpiece is not only free of oil, rust and dust on the surface, but also forms a layer of uniform and rough gray phosphating film that is not easy to rust on the original silver gloss surface, which can play a role in rust prevention. And a spray coating is added.

2、靜電噴涂

2. Electrostatic spraying

用途：將粉末涂料均勻噴涂在工件表面，尤其是工件（包括容易產(chǎn)生靜電屏蔽的位置）或使用高性能靜電噴涂機(jī)完成噴涂。

Usage: evenly spray powder coating on the surface of workpieces, especially workpieces (including positions prone to electrostatic shielding) or finish spraying with high-performance electrostatic spraying machine.

技術(shù)流程：

Technical process:

利用靜電吸附原理，在工件表面均勻噴涂一層粉末涂料；落下的粉末通過回收系統(tǒng)回收，篩分后可重復(fù)使用。

Using the principle of electrostatic adsorption, evenly spray a layer of powder coating on the surface of the workpiece; The fallen powder is recycled through the recycling system and can be reused after screening.

3、高溫固化

3. High temperature curing

目的：將工件表面的粉末涂料加熱到一定溫度，并保持相應(yīng)的時(shí)間使其熔化、流平、固化，從而獲得工件所需的表面效果。

Objective: to heat the powder coating on the surface of the workpiece to a certain temperature and keep it for a corresponding time to melt, level and solidify, so as to obtain the surface effect required by the workpiece.

工藝流程：將噴涂好的工件推入固化爐，加熱預(yù)定溫度（一般為185度），并保持相應(yīng)的時(shí)間（15分鐘）；打開爐子，取出冷卻即可得到產(chǎn)品。

Process flow: push the sprayed workpiece into the curing furnace, heat it to a predetermined temperature (generally 185 degrees), and keep it for a corresponding time (15 minutes); Turn on the stove, take out the cooler and get the product.

提示：加熱及控制系統(tǒng)（包括電加熱、燃油、燃?xì)狻⒚旱燃訜岱绞剑┍叵?固化爐。

Prompt: heating and control system (including electric heating, oil, gas, coal and other heating methods) incubator = curing furnace.

4、裝修與處置：

4. Decoration and disposal:

意圖：使靜電噴涂后的工件達(dá)到一定的特殊外觀，如：各種木紋、條紋、長(zhǎng)面等。

Intention: make the workpiece after electrostatic spraying achieve a certain special appearance, such as various wood grains, stripes, long surfaces, etc.

以上是電纜橋架表面采取的防靜電措施，希望以上介紹可以幫助到你。另外電纜橋架本身沒有強(qiáng)弱電之分，但對(duì)安裝有一定要求。更為詳細(xì)的內(nèi)容就來我們網(wǎng)站http://m.ymmgjx.net咨詢了解吧。

The above are the anti-static measures taken on the surface of the cable tray. I hope the above introduction can help you. In addition, there is no strong or weak current in the cable tray itself, but there are certain requirements for installation.
