1)下层处理外墙下层上出现的有碍粘结的因素及处理办法。

1) primary processing factors of exterior wall base on the bond and hinder approach.


2)防污条、防污纸粘贴外墙对美观要求较高,因此施工时应粘贴好防污条和防污纸(河南人事考试网首页),但同时也不能使防污条上的粘胶浸入到密封胶中去。

2) anti fouling strip, anti fouling paper paste the external walls of the higher requirements, so the construction should be pasted with anti fouling and anti fouling paper, but also can not make the adhesive on the anti fouling strip immersed in the sealant.


3)底涂料施工底涂料起着承上启下的作用,使界面与密封材料之间的粘结强度有所进步,因此应认真地涂刷底涂料。底涂料的施工环境如下:施工温度不能太高,以免有机溶剂在施工前就挥发完了。施工界面的湿度不能太大,以免粘结困难。基面外观不应结露。

3) primer primer construction plays a very important role to make the interface bond strength and sealing material between improved, and should therefore be carefully brushing primer. The construction environment of the bottom coating is as follows: the construction temperature can not be too high, so as to avoid the organic solvent before the construction of volatile. The construction interface of the humidity can not be too large, so as not to bond difficult. The base surface should not be dew.


4)嵌填密封材料确定涂料已经干燥,但未超过24h时便可开始嵌填密封材料。充填时,金属幕墙、PC幕墙、各种外装板、混凝土墙应从纵横缝交叉处开始;施工时,枪嘴应从接缝底部开始,在外力作用下先让接缝材料充满枪嘴部位的接缝(豪沃A7驾驶室),渐渐向后退,每次退的时候都不能让枪嘴露出在密封材料表面百度优化,以免气泡混入其中。

4) the sealing material has been dried, but the sealing material can be started when the material is not more than 24h. When filling, metal curtain wall, curtain wall, all kinds of PC plate and concrete wall should be vertical and horizontal seam intersections; construction, from the bottom to the gun nozzle joint, under the action of external force let joint material full of gun nozzle parts of the joint, gradually backward, every time back will be able to let the gun mouth exposed in the outside sealing material, so as to avoid the mixing of air.
