At present, the manufacturing process of most effective steel containers in China is as follows:

鋼材開卷、軋平→剪切→拋丸→噴車間底漆→烘干→冷加工、成型→部件組裝、焊接→總裝配、焊接→整箱焊噴砂→預(yù)徐底讀→噴底漆平、烘干→中層漆、內(nèi)面漆預(yù)涂→中層漆、外面漆噴涂→流平、烘干→外面漆預(yù)涂。外面漆噴徐→流平，烘干→完工線裝配→銘牌、密封膠、標貼→箱底瀝青漆及水密試驗一成品箱出線。

Steel uncoiling and flattening → shearing → shot blasting → shop primer spraying → drying → cold processing and forming → component assembly and welding → general assembly and welding → whole box welding and sand blasting → pre Xu bottom reading → first-class leveling and drying of primer spraying → precoating of middle paint and inner finishing coat → spraying of middle paint and outer paint → leveling and drying → precoating of outer paint. External paint spraying → leveling and drying → assembly of finished line → nameplate, sealant and label → asphalt paint at the bottom of the box and water tightness test - outgoing line of finished box.

從上述工藝流程可以看出，集裝箱除裝要與整個集裝箱制造工藝過程相適應(yīng)。在流水線的涂裝工位上，如在焊縫噴砂及中層漆、面漆噴涂中超時工作或出了紕漏,就會造成生產(chǎn)節(jié)拍放慢或全線癱瘓。以噴漆為例，無論是自動噴漆,還是手工噴漆,必須達到要求,符合生產(chǎn)節(jié)拍,7一8 分鐘內(nèi)完成噴漆及供干。如果外面漆、漆膜末烘千，無法進行工線的裝配和商標黏貼等;一次噴漆的厚度必須達到規(guī)定膜厚的要求,且膜厚均勻;涂層外觀質(zhì)量無針孔、氣袍、流掛等現(xiàn)象。

From the above process flow, it can be seen that the container unloading should adapt to the whole container manufacturing process. In the painting station of the assembly line, if overtime work or mistakes are made in weld sand blasting, middle paint and finish paint spraying, the production pace will slow down or the whole line will be paralyzed. Take painting as an example. Whether it is automatic painting or manual painting, it must meet the requirements, meet the production beat, and complete painting and drying within 7-8 minutes. If the exterior paint and paint film are baked for thousands, the assembly of the work line and trademark pasting cannot be carried out; The thickness of one-time painting must meet the requirements of the specified film thickness, and the film thickness must be uniform; The appearance quality of the coating is excellent, without pinholes, gas robes, sagging and other phenomena.
