一、钢闸门的管理与维护1.防锈防止钢闸门的锈蚀,常用的有油漆防锈、柏油掺和水泥防锈、喷锌防锈3种。(1)油漆防锈包括除锈与涂漆2道工序。第1道工序是除锈,涂油漆前,必须彻底除锈。目前常用的除锈方法是机械除锈法,即用空气压缩机把砂子喷到闸门上,将铁锈除去。第2道工序是涂漆。一般常用的是环氧云铁防锈漆打底,银灰色沥青漆涂面。先刷底漆,再刷面漆2遍。沥青是1种防锈材料。涂刷沥青时应先将锈物擦洗干净,然后用高温的沥青液涂刷板面。厚度要适当,防止花斑、露底、流淌、起皱等现象。
First, the management and maintenance of steel gate 1. Rust prevention to prevent the rust of steel gate, commonly used paint rust, asphalt blended rust, zinc spray rust 3. (1) paint rust, including rust and paint 2 processes. The first process is rust, painted paint, you must thoroughly rust. At present, the commonly used method of descaling is the mechanical descaling method, that is, the sand is sprayed onto the gate by the air compressor to remove the rust. The second process is painting. Commonly used epoxy cloud iron rust primer, silver gray asphalt paint surface. First brush primer, brush topcoat 2 times. Asphalt is a rust-proof material. When brushing asphalt rust should be scrubbed clean, and then coated with high temperature asphalt fluid board. Thickness should be appropriate to prevent the spot, exposed, flowing, wrinkling and so on.
