Processing disposal of cable bridge before spraying plastic.

1、酸洗，脫脂，磷化，水洗，烘干;

1. pickling, degreasing, phosphating, washing and drying;

酸洗的作用：經(jīng)過(guò)鹽酸的浸泡，將電纜橋架鋼材里外的銹全部除去。優(yōu)點(diǎn)：除銹完全; 缺陷：用后的的鹽酸溶液不容易處置，部門(mén)正在逐步要求取締酸洗化作業(yè)，且焊縫處有能夠會(huì)呈現(xiàn)氫脆景象。

The function of pickling: After soaking in hydrochloric acid, the rust inside and outside the steel of cable bridge is removed completely. Advantages: complete rust removal; defects: the used hydrochloric acid solution is not easy to dispose of, environmental protection departments are gradually demanding that acid pickling be banned, and there is hydrogen embrittlement at the weld.

2、噴砂，磷化，水洗，烘干;

2. Sandblasting, phosphating, washing and drying;

磷化的作用：在電纜橋架鋼材外表構(gòu)成一層磷化膜，這層磷化膜的作用有2個(gè)：一是進(jìn)步噴塑層與電纜橋架鋼材的結(jié)合力，二是帶有防銹作用。

The function of phosphating is to form a layer of phosphating film on the steel surface of cable bridge, which has two functions: one is to improve the bonding force between plastic spraying layer and steel of cable bridge, the other is to have anti-rust effect.

3、噴砂，人工擦拭。

3. Sandblasting and manual wiping.

噴砂的作用：經(jīng)過(guò)高速高壓的小鐵珠將鋼材外表的銹除去，同時(shí)在鋼材外表構(gòu)成一些肉眼看不到的小凹坑，這些小凹坑的存在可以協(xié)助進(jìn)步噴塑層的附著力。缺陷：無(wú)法去除空心型材外部的銹，本錢(qián)較高。

Sandblasting effect: After high-speed and high-pressure small iron beads to remove the rust on the steel surface, and at the same time in the steel surface to form some small pits invisible to the naked eye, the existence of these pits can help improve the adhesion of the spray layer. Defects: It is impossible to remove the rust from the outside of hollow profiles, and the cost is high.

山東電纜橋架的日常頤養(yǎng)辦法

Daily Maintenance of Cable Bridge Frame in Shandong Province

1.橋架的日常頤養(yǎng)：運(yùn)用潔凈的軟布常常性的揩凈外表塵跡便可。切忌運(yùn)用濕布、硬物抹擦汕漆外表和鏡子、玻璃。切忌與酸、堿性化學(xué)物品及清淡物接觸。

1. Daily maintenance of the bridge: clean soft cloth is often used to wipe clean the surface dust. Do not use wet cloth, hard objects to wipe Shanshan paint appearance and mirror, glass. Do not contact with acid, alkaline chemicals and light substances.

2.橋架的活期頤養(yǎng)：普通可每季度頤養(yǎng)一次。軟軟布揩凈外表塵跡后，用公用的上光蠟平均涂擦外表，稍待后再用潔凈軟布擦亮，防潮。五金配件、金屬拉手可用少些機(jī)油抹擦并擦干，使之能靈敏轉(zhuǎn)動(dòng)和防銹抗氧化。

2. Bridge frame's current accommodation: generally can focus on accommodation once a quarter. After the soft cloth wipes off the surface dust, it rubs the surface with the common polishing wax on average, and then rubs the surface with the clean soft cloth after a while, which is moistureproof. Hardware fittings and metal handles can be wiped and dried with less oil to enable them to rotate sensitively and resist rust and oxidation.

3.應(yīng)防止橋架擺放在低溫濕潤(rùn)的，應(yīng)堅(jiān)持居室通風(fēng)枯燥。

3. Bridge frames should be prevented from being placed in low-temperature and humid centers, and bedroom ventilation should be insisted on.

4.防止讓橋架外表接觸到腐蝕性液體，如酒精、指甲油等。

4. prevent contact with corrosive liquids such as alcohol, nail polish and so on.

5.應(yīng)該用干潔的軟布，運(yùn)用公用頤養(yǎng)蠟。

5. We should use dry soft cloth and public wax.
