材料配比及搅拌方法(Blending Ratio and Method of Preparation)
1 、 A 、 B 、 C 三组份中每组份均为 2 平方米使用量(Eash of the component A,B,C use for 2m 2 )
2 、施工时先将 A 组份与 B 组份注入搅拌机中进行搅拌 , 待混合均匀然后再加入 C 组份进行搅拌 , 使之成为均匀稠泥状物即可 .( Feed component B and C into the agitator first and mix When they are mixed evenly, feed in component A and continue mixing. The coveting is ready for application when it IS even and in a state like thick mud.)
施工注意事项 :(Construction notice)
•  钢甲板必须火工校正 , 所有影响敷料设的安装和焊接工作均应结束.
•  清除基层钢板上的杂物 , 并按 CB3230 中 P2 级除锈标准除锈.
•  施工时将已搅拌好的敷料敷设在基层钢板上 , 用泥板将敷料在钢板上来回搓动 , 使钢板充分接触敷料促凝剂 , 然后用木质直尺将敷料刮平到规定厚度 , 经 30min 左右 , 再用泥板压实 , 泥平 , 如表面稍干 , 可洒少量乳胶液再行泥平 .
•  敷料中的乳胶液为高分子材料 , 故搅拌时不宜用高速搅拌机 ( 器 ) 搅拌 , 搅拌速度建议为 34r.P.m, 搅拌时间为 3-5min.
•  整个敷设及养护期间 , 环境温度宜在 5 ℃ -30 ℃ + 高于或低于环境温度应采取降温或保温措施 .
•  施工后敷料必须养护 1-2 天 , 待固化后方可进入施工场所 .
•  各类材料应避免阳光曝晒、雨水浸渍 , 并在规定气温内保存 , 材料保质为三个月 .
•  Steel plate fairing is to be carried out by hot working. Installation or welding that may interfere with the application of covering are to be finished beforehand .
•  Impurities on steel plates are to be removed meanwhile rest is to be removed according to the requirements ofGrade P 2 in CB3230.
•  Pour the mixed coveting onto the steel plate, rub the covering bach and forth on the plate with a towel to moisture the plate sufficiently with the promote , then trim the covering to the specified thickness with a wooden ruler Consolidate the covering layer with a trowel after 30minutes and surface flush if the surface is a bit too hard for leveling , spray some emulsion first.
•  The emulsion for the covering is made of polymer substances so it is not proper to stirrer it with a higt-speed agitatior. Stirring is to be applied at a speed 34r.p.m and it is to last 3to 5minutes.
•  In the whole maintenance period, the environmental temperature may range from 5 ℃ to 3 ℃ ,measures arc to be taken to maintain such a temperature range if the temperature exceeds the limits.
•  When the covering is applied , it should be kept for 1 to 2 days for gull solidification before the structure is transported to the construction site.
•  All materials are to be stored ferr from sunlighe, rain soak and under specified tem perature. Their quality assurance period is 3 months.
