冷鍍鋅電纜橋架是利用電解設(shè)備將電纜橋架經(jīng)過除油酸洗、后放入成分為鹽的溶液中，并連接電解設(shè)備的負(fù)極，在電纜橋架的對面放置鋅版，連接在電解設(shè)備的正極接通電源，利用電流從正極向負(fù)極的定向移動就會在電纜橋架上沉積一層鋅，冷鍍電纜橋架是先加工后鍍鋅；鋅層表面應(yīng)光滑均勻，致密。不得有起皮、氣泡、花斑、局部未鍍、劃傷等缺陷。

Cold galvanized cable tray is a method of using electrolytic equipment to remove oil and acid from the cable tray, then placing it in a solution containing salt, and connecting it to the negative electrode of the electrolytic equipment. A zinc plate is placed opposite the cable tray, connected to the positive electrode of the electrolytic equipment and connected to the power supply. The directional movement of current from the positive electrode to the negative electrode will deposit a layer of zinc on the cable tray. Cold galvanized cable tray is processed first and then galvanized; The surface of the zinc layer should be smooth, uniform, and dense. There must be no defects such as peeling, bubbles, spots, partial non plating, scratches, etc.

熱鍍鋅電纜橋架：成品酸洗-水洗-加助鍍液-烘干-掛鍍-冷卻-藥化-清洗-打磨-熱鍍鋅完工。是一種有效的金屬防腐方式，主要用于各行業(yè)的金屬結(jié)構(gòu)設(shè)施上。是將除銹后的鋼件浸入500℃左右融化的鋅液中，使鋼構(gòu)件表面附著鋅層，從而起到防腐的目的，一般可用于室外。

Hot dip galvanized cable tray: finished acid pickling - water washing - adding auxiliary plating solution - drying - hanging plating - cooling - medicating - cleaning - polishing - hot-dip galvanizing completed. It is an effective method of metal corrosion prevention, mainly used for metal structural facilities in various industries. It is to immerse the rust removed steel parts in a molten zinc solution at around 500 ℃, so that a zinc layer is attached to the surface of the steel components, thereby achieving the purpose of corrosion prevention. It can generally be used outdoors.

熱噴鋅涂層表面由分布均勻的鋅粒組成，其粗糙程度對噴漆具有很好的附著力，使漆面不易脫落。同時又不會造成漆面不光滑而影響美觀。熱噴鋅不會對工件造成變型。因?yàn)闊釃婁\只在工作表面產(chǎn)生瞬間高溫，不會任何工件發(fā)生形變，噴涂應(yīng)平整、光滑、均勻、不起皮、無氣泡水泡。

The surface of the hot spray zinc coating is composed of evenly distributed zinc particles, and its roughness has good adhesion to the spray paint, making the paint surface less prone to peeling off. At the same time, it will not cause the paint surface to be uneven and affect the appearance. Hot spraying zinc will not cause deformation of the workpiece. Because hot spraying zinc only generates instantaneous high temperatures on the working surface and will not cause any deformation of the workpiece, the spraying should be flat, smooth, uniform, without peeling, and without bubbles or water bubbles.

熱浸鍍鋅的托盤、橋架要求鍍層表面均勻，無毛刺、過燒、掛灰、傷痕、局部未鍍鋅（直徑2mm以上）等缺陷，不得有影響安裝的鋅瘤。螺紋的鍍層應(yīng)光滑，螺栓連接件應(yīng)能擰入。橋架焊縫表面均勻，不得有漏焊、裂紋、夾渣、燒穿、弧坑等缺陷。

Hot dip galvanized trays and cable trays are required to have a uniform coating surface, without defects such as burrs, overburning, hanging dust, scratches, and partial non galvanizing (diameter of 2mm or more), and must not have zinc nodules that affect installation. The coating of the thread should be smooth, and the bolted connections should be able to be screwed in. The surface of the welding seam on the bridge should be uniform and free of defects such as missed welding, cracks, slag inclusion, burning through, and arc pits.

噴塑電纜橋架是將塑料粉末噴涂在電纜橋架上的一種表面處理方法。不需稀料，施工對環(huán)境無污染，對人體害；涂層外觀質(zhì)量優(yōu)異，附著力及機(jī)械強(qiáng)度強(qiáng)；噴涂施工固化時間短；涂層耐腐耐磨能力高出很多；不需底漆；施工簡便，對工人技術(shù)要求低；成本低于噴漆工藝；有些施工場合已經(jīng)明確提出必須使用靜電噴塑工藝處理；靜電噴粉噴涂過程中不會出現(xiàn)噴漆工藝中常見的流淌現(xiàn)象。

Spraying plastic cable tray is a surface treatment method that sprays plastic powder onto the cable tray. No need for diluents, construction is pollution-free to the environment and non-toxic to human health; The coating has excellent appearance quality, strong adhesion and mechanical strength; Short curing time for spray painting construction; The corrosion resistance and wear resistance of the coating are much higher; No primer required; Easy construction with low technical requirements for workers; The cost is lower than the painting process; Some construction scenarios have explicitly stated that the use of electrostatic spraying technology is necessary for treatment; During the electrostatic powder spraying process, there will be no common flowing phenomenon in the painting process.

防火電纜橋架外觀與噴塑電纜橋架比較相似，不過性能完全不同，防火電纜橋架主要性能是防火，有一定的防火等級，常用于有防火要求的場所，表面粗糙，表面摸起來會有粗糙斜斜的感覺，當(dāng)遇到火災(zāi)后不會燃燒，并且可以阻隔火勢繼續(xù)蔓延下去，起到一定的防火作用，防火涂層可以針對施工環(huán)境設(shè)計(jì)去選擇橋架的顏色。

Fireproof cable trays have a similar appearance to spray painted cable trays, but their performance is completely different. Fireproof cable trays mainly have fire resistance, with a certain fire rating, and are commonly used in places with fire protection requirements. The surface is rough, and there is a rough and inclined feeling when touched. When encountering a fire, it will not burn and can block the fire from continuing to spread, playing a certain role in fire prevention, Fireproof coatings can be designed to choose the color of the bridge according to the construction environment.
