◆ 施工工艺Construction technology

对钢材表面喷砂除锈,达到国际标准Sa2.5-Sa3级。除锈质量的好坏是整个涂装质量的关键。黑色金属表面一般都存在氧化皮和铁锈,在涂装之前必须将它们除尽,不然会严重影响涂层的附着力使用寿命,造成经济损失,而所有除锈方法中,以喷砂除锈为最佳;因为它即能除去氧化皮和铁锈,又能在金属表形成一定的粗糙度,增加了涂层与金属表面之间的结合力。

The surface of steel blast cleaned up to the international standard, Sa2.5-Sa3 level. The stand or fall of quality derusting is the key of the coating quality. Black metal surface generally exist oxide skin and rust, coating must be in before they consume, or you will seriously affect the service life of the coating adhesion, economic losses, and all derusting method, to blast cleaned for best; Because it is able to remove oxide skin and rust, and can in metal table formed certain roughness, increased the coated with metal surface adhesion between.

 

油罐外壁的施工 传统的喷砂处理工艺

Construction of the outer wall of Oil tank     The traditional sandblasting processing technology

 

一般施工单位都采用干法喷砂除锈,一般用铜砂或钢砂等作为磨料,以5-7kg/cm2压力的干燥洁净的压缩空气带动磨料喷射金属表面,可除去钢材表面的氧化皮和铁锈。一般采用6m3/min的电动空压机和开放式喷砂机来完成喷砂除锈作业的;一套开放式喷砂机组每小时的工作能力为4-6m2(喷砂除锈达到Sa3级),假定每一工作日要完成约150m2的工作量;用4套开放式喷砂机组(1套喷砂机组备用),施工人员需要6-15人按每天开2班施工配备,这样才完全可以满足工程进度所需。

首先,搭设施工临时设施及脚手架;然后将施工机具就位,接通电源。采取三班倒、二个施工组在油罐直径两端同时操作的作业方法,以缩短施工周期。为保证涂装质量避免喷砂以后间隔时间过长而发生返锈现象,尽量缩短喷砂与喷涂金属的时间间隔(4小时内进行),采用局部完工法进行喷砂与涂装。施工时自上而下施工。确定环境温度、相对湿度等满足施工要求;喷砂除锈:彻底去除油罐外壁的旧涂层与锈垢,金属出白,达到Sa3级,粗糙度Rz 40-80μm,检测合格后,将表面清洁干净,4个小时内进行涂装,施工完成后,拆除脚手架。使用吸砂机(2台)清理遗留磨料。

 

General construction unit USES dry blast cleaned, generally with the copper sand or steel grit as abrasive, with 5-7 kg/cm2 pressure dry clean compressed air drive abrasive jet metal surface, can remove the steel surface oxide skin and rust. General use of the 6 m3 / min electric air compressor and open sandblasting machine to finish the homework blast cleaned; A set of open gush arenaceous units each hour of work ability for four to six m2 (blast cleaned achieve Sa3 level), assume that every working days to complete the workload of about 150 m2; With four sets of open gush arenaceous units (1 set of gush arenaceous unit set aside), construction workers need 6 to 15 people every day 2 class construction according to open, so that was completely equipped with progress can meet the engineering need.

First of all, to set the temporary facilities and scaffold construction; Then will construction tools in place, processing power. Take 3, two construction group in the oil tank diameter and operation method of the homework at both ends, in order to shorten the construction period. To ensure the quality of coating avoid gush arenaceous later time interval is too long and happen to rust phenomenon, try to shorten sandblasting and spraying metal interval of time (4 hours), and use local completion method and coating sandblasting. When construction top-down construction. Determine the environment temperature, relative humidity and so on meet the construction requirements; Blast cleaned: completely remove the oil tank of the outer wall of the old rust, metal coating and scale, the white to Sa3 level, roughness Rz 40-80 μ m, qualified, will clean surface, four hours for painting, and after the completion of the construction, dismantled scaffold. Use suck sand machine (2 Taiwan) cleaning legacy abrasive.

清理效率计算

垂直遥控自动爬行喷砂机350A30M2/H * 8H = 240M2/天 使用开放喷砂补充未能处理的表面6M2/H*6H = 36M2/天 每天两班3-6名工人,实际操作小时14小时,处理面积270M2,是传统喷砂工艺的1.8倍,人工减少8-10人,并节约脚手架搭建和拆除时间,表面清理效果不受人为影响,十分均匀。工人劳动强度大大降低,对环境的污染大大降低。

 

Cleaning efficiency calculation

Vertical remote automatic crawl sandblasting machine 350 A30M2 / H * 8 H = 240 M2 / day use open gush arenaceous added failed to deal with the surface of 6 M2 / H * 6 H = 36 M2 / day two class every day 3-6 a worker, the actual operating hours 14 hours, processing area of 270 M2, the traditional gush arenaceous technology of 1.8 times, artificial 8-10 people, reduce and save time and dismantled scaffold structures, surface cleaning effect from human impact, very evenly. Workers labor strength greatly reduce, the environmental pollution is reduced greatly.

可以看出自动爬行设备具有喷砂效率高、操作方便、节省劳动力和能源、环保无尘施工等优点,完全满足大面积防腐蚀涂装施工工期短、质量高和无尘生产的要求。

 

根据底板施工的技术和质量要求,考虑到晚上和清晨钢板冷却,容易凝结露水,因此喷砂除锈的工作宜安排在早8时到晚6时的这10h进行,平均每小时需要喷砂除锈的表面按100M2。要完成如此繁重的喷砂除锈任务,对2种喷砂方式进行了比较,如表。

According to the bottom of the construction technology and quality requirements, considering the night and early in the morning dew, easy to steel cooling setting, so blast cleaned work should be arranged in early June 8 when the late this 10 h, on average every hour need to blast cleaned surface according to 100 M2. To accomplish such a heavy blast cleaned task, the two kinds of gush arenaceous way is compared, as the chart.
