  噴粉室

  噴粉室： 工件通過輸送鏈進入噴粉房的噴槍位置準備噴塗作業,靜電發生器通過噴槍槍口的電極針向工件方向的空間釋放高壓靜電(負極)，該高壓靜電使從．噴槍口噴出的粉末和壓縮空氣的混合物以及電極周圍空氣電離(帶負電荷)。鋼管經過掛具通過輸送鏈接地(接地極)，這樣就在噴槍和工件之間形成一個電場占粉末在電場力和壓縮空氣壓力的雙重推動下到達工件表麵，依靠靜電吸引在鋼管表麵形成一層均勻的塗層。 Powder spraying chamber: the workpiece enters the spray gun position of the powder spraying chamber through the conveying chain to prepare for spraying. The electrostatic generator releases high-voltage static

  塗膠+PE纏繞擠出機

  塗膠+PE纏繞擠出機：膠粘劑纏繞：由於聚乙烯層與熔結環氧塗層粘接力較差，利用膠粘劑提高熔結環氧塗層與聚乙烯層兩種不同極性材料粘接力，膠粘劑的塗敷必須在環氧粉末膠化過程中進行。 Gluing + PE winding extruder: adhesive winding: due to the poor adhesion between polyethylene layer and fusion bonded epoxy coating, the adhesive is used to improve the adhesion between fusion bonded epoxy coating and polyethylene layer, and the application of adhesive must be carried out in the process of epo

  噴淋房

  噴淋房：鋼管經3PE塗敷後，進入冷卻室進行降溫定型。冷卻室配備升降噴淋裝置，可根據3PE管徑大小進行調節，根據不同管徑的3PE產品通過控製流量來實現降溫定型。冷卻室內的驅動部分均配備水隔離裝置從而起到保護電氣元件的作用。 Spray room: after 3PE coating, the steel pipe enters the cooling room for cooling and finalization. The cooling room is equipped with lifting spray device, which can be adjusted according to the size of 3PE pipe diameter, and the cooling and finalization can be realized by controlling th
