Cable trays can be used everywhere in our life. They protect cables from being damaged by the outside world, and there are many different types of cable trays. It is understood that the surface treatment methods of different cable trays are different. Different cable trays are used in different environments. Let's look at the differences in surface treatment of cable trays.
Hot dip galvanized cable tray: finished product Pickling - water washing - adding auxiliary plating solution - drying - hanging plating - cooling - medicating - Cleaning - polishing hot dip galvanizing is completed. It is an effective metal corrosion prevention method, mainly used in metal structure facilities in every industry. It is to immerse the derusted steel parts into the molten zinc at about 500 ℃, so that the zinc layer is attached to the surface of the steel members, so as to achieve the purpose of corrosion prevention
在这里告诉大家热喷锌涂层表面由分布均匀的锌粒组成，其粗糙程度对喷漆具有很好的附着力，使漆面不易脱落。同时又不会造成漆面不光滑而影响美观。 热喷锌不会对工件造成变型。 因为热喷锌只在工作表面产生瞬间高温，不会至任何工件发生形变。
Here we tell you that the surface of the hot sprayed zinc coating is composed of evenly distributed zinc particles, and its roughness has good adhesion to the paint, so that the paint surface is not easy to fall off. At the same time, it will not cause the paint surface to be not smooth and affect the appearance. Hot spraying zinc will not cause deformation to the workpiece. Because the hot spraying zinc only produces instantaneous high temperature on the working surface, it will not cause deformation to any workpiece.
Spray plastic cable tray: it is a surface treatment method of spraying plastic powder on the cable tray. No thinner is required, the construction will not pollute the environment and will not harm the human body; The coating has excellent appearance quality, strong adhesion and mechanical strength; The curing time of spraying construction is short; The corrosion and wear resistance of the coating is much higher; No primer is required; Simple construction and low technical requirements for workers; The cost is lower than the painting process; Some construction sites have clearly proposed the use of electrostatic spraying process; There will be no common flow phenomenon in the process of electrostatic powder spraying.
Cold galvanized cable tray: it is to use the electrolytic equipment to wash the cable tray with oleic acid and then put it into the solution containing salt, connect the negative electrode of the electrolytic equipment, place a zinc plate on the opposite side of the cable tray, connect the positive electrode of the electrolytic equipment to the power supply, and use the current to move from the positive electrode to the negative electrode to deposit a layer of zinc on the cable tray. The cold galvanized cable tray is processed first and then galvanized.
Fire resistant cable tray: the appearance of fire-resistant cable tray is similar to that of spray plastic tray, but the performance is completely different. The main performance of fire-resistant cable tray is fire protection. It has a certain fire rating. It is often used in places with fire protection requirements. The surface is rough and the surface feels rough and oblique. It will not burn in case of fire, and can prevent the fire from continuing to spread, playing a certain fire protection role, The fireproof coating can be designed to select the color of the bridge according to the construction environment.
