根據(jù)現(xiàn)場(chǎng)活動(dòng)板房建造的實(shí)際情況確定的工藝流程為：除銹、基面清理----底漆涂裝----防火漆涂裝----面漆涂裝----檢查驗(yàn)收。下面來(lái)講講活動(dòng)板房建造時(shí)的角鐵支架腐蝕修復(fù)措施內(nèi)容吧。

The process flow determined according to the actual situation of the construction of the movable plank house on site is: rust removal, base surface cleaning - primer coating - fireproof paint coating - finish coating - Inspection and acceptance. Next, let's talk about the measures to repair the corrosion of angle iron support during the construction of prefabricated houses.

1、除銹、基面清理：

1. Derusting and base surface cleaning:

先將需涂裝部位的鐵銹、舊漆膜、油 污、塵土等雜物清理干凈，用干刷、干凈的抹布或通過(guò)壓縮空氣的辦法將鋼材表面的灰塵干凈，再進(jìn)行油漆涂刷。

First clean up the rust, old paint film, oil stain, dust and other sundries at the parts to be coated, and then clean the dust on the steel surface with a dry brush, a clean rag or compressed air, and then apply the paint.

2、底漆涂裝：

2. Primer coating:

溶劑型環(huán)氧富鋅底漆2道，漆膜厚度80μm。在基面清理不超過(guò)4-6小時(shí)內(nèi)清理除塵，涂刷底漆?？刂朴推岬恼扯?、稠度、稀度，兌制時(shí)應(yīng)充分的攪拌，使油漆色澤、粘度均勻一致。

Two coats of solvent based epoxy zinc rich primer with film thickness of 80 μ m。 Dust shall be removed and primer shall be applied within 4-6 hours after the base surface is cleaned. Control the viscosity, consistency and thinness of the paint, and fully stir it when cashing to make the paint color and viscosity uniform.

除有特殊要求外，施工的環(huán)境溫度宜為5~38℃，相對(duì)濕度不大于85%。 涂料開(kāi)桶前，應(yīng)充分搖勻。開(kāi)桶后原漆應(yīng)不存在結(jié)皮、結(jié)塊、凝膠等現(xiàn)象，有沉淀應(yīng)能攪起，使油漆色澤、粘度均勻一致。

Except for special requirements, the ambient temperature for construction should be 5~38 ℃, and the relative humidity should not be greater than 85%. The paint shall be fully shaken before opening the barrel. After the barrel is opened, the original paint should be free of crusting, caking, gel and other phenomena. If there is precipitation, it should be able to stir up, so that the paint color and viscosity are uniform.

調(diào)整粘度必須使用專(zhuān)用稀釋劑，如需代用，必須經(jīng)過(guò)試驗(yàn)。 刷層底漆時(shí)涂刷方向應(yīng)該一致，接槎整齊，刷漆時(shí)應(yīng)采用勤沾、短刷的原則，防止刷子帶漆太多而流墜。

Special diluent must be used for viscosity adjustment. If it needs to be substituted, it must be tested. When brushing the first layer of primer, the brushing direction should be consistent and the joint should be neat. The principle of frequent dipping and short brushing should be adopted to prevent the brush from falling due to too much paint.

待遍刷完后，應(yīng)保持一定的時(shí)間間隙，防止遍未干就上第二遍，這樣會(huì)使漆液流墜發(fā)皺，質(zhì)量下降。

After the first painting, a certain time gap should be maintained to prevent the second painting before the first one is dry, which will make the paint flow, wrinkle and reduce the quality.

待遍干燥后，再刷第二遍，第二遍涂刷方向應(yīng)與遍涂刷方向相反，這樣會(huì)使漆膜厚度均勻一致。底漆涂裝后起碼間隔24h后才涂裝中間漆。

After the first time is dry, brush the second time. The direction of the second time should be opposite to that of the first time, which will make the film thickness uniform. The intermediate paint shall be applied at least 24 hours after the primer is applied.

3、防火漆：

3. Fire retardant paint:

超薄型露天用防火涂料，采用滾涂的方法進(jìn)行涂裝當(dāng)?shù)淄繉雍穸确显O(shè)計(jì)要求，并基本干燥后，方可進(jìn)行防火涂料涂裝。防火涂料一般涂刷1~2道，如遍是從左右涂刷，第二遍則應(yīng)從右左涂刷，以確保全部覆蓋住底涂層。

The ultra-thin fire-proof coating for outdoor use shall be applied by rolling coating method. When the thickness of the primer meets the design requirements and is basically dry, the fire-proof coating can be applied. Generally, the fire-proof coating is applied 1-2 times. If the first time is from left to right, the second time is from right to left, so as to ensure that all the primer is covered.

4、面漆涂裝：

4. Finish painting:

涂刷環(huán)氧云鐵中間漆2道，漆膜厚度80μm。氟碳面漆2道，漆膜厚度50μm。漆料兌制的稀料應(yīng)合適并充分?jǐn)嚢?，其工作粘度、稠度?yīng)保證涂裝時(shí)不流墜，不顯刷紋，涂刷的方法和方向與底漆相同。濟(jì)南活動(dòng)板房面漆的調(diào)制應(yīng)選擇顏色完全一致的面漆，使用過(guò)程中應(yīng)不斷攪和，保持 色澤均勻。

Brush two layers of epoxy micaceous iron intermediate paint, with a film thickness of 80 μ m。 Two fluorocarbon finishing coats, film thickness 50 μ m。 The thinner prepared by the paint shall be suitable and fully stirred, and its working viscosity and consistency shall ensure that there is no sagging and brush lines during coating, and the brushing method and direction are the same as that of the primer. The finish paint of Jinan movable plank house should be completely the same in color, and should be continuously stirred during use to maintain uniform color.

5、檢查驗(yàn)收：

5. Inspection and acceptance:

涂裝后涂層顏色一致，不起皺皮，不起疙瘩。

After coating, the color of the coating is consistent, without wrinkle and pimple.
