厚型钢结构防火涂料粘结强度与什么有关?
发表时间:2018-08-23 15:38:43来源:/

因厚型钢结构防火涂料在涂刷施工的时,若要达到相应的耐火极限,其涂刷的厚度比薄涂型防火涂料要厚的多,这就要求厚型钢结构防火涂料在施工时,要特别注重防火涂料与基材的粘结强度,下面是影响厚型钢结构防火涂料的粘结强度的原因及处理方案:

Because the thickness of thick steel structure fire-retardant coatings is much thicker than that of thin-coated fire-retardant coatings if the fire-retardant limit of thick steel structure is to be reached, it is necessary to pay special attention to the bond strength between fire-retardant coatings and substrate during the construction of thick steel structure fire-retardant coatings. The reason and treatment plan of bond strength are:
一、基层防腐质量低劣,强度不够;
First, the quality of anti-corrosion at the grass-roots level is poor and the intensity is not enough.
二、未加707胶;
Two. 707 glue was not added.
三、涂料搅拌时间不够,料为熟;
Three, paint mixing time is not enough, the material is cooked.
四、基层表面过潮或结水珠;
Four, the surface of the grassroots is over tidal or water droplets.
处理方案:
Treatment plan:
1、检查防腐漆是否合格,如果有严重质量缺陷,涂料施工方可重请技术员做技术处理;
1. Check whether the anticorrosive paint is qualified, if there are serious quality defects, coating construction can re-invite technicians to do technical treatment;
2、表面清理:
2. Surface cleaning:
①清除表面的浮尘及杂物;

First, remove the floating dust and debris on the surface.
②将707胶加入按1:1稀释,在涂层表面涂刷一遍,要求无漏涂并均匀;
(II) add 707 glue to 1:1, dilute it, and apply it on the surface of the coating.
③第一遍防火涂料喷雾需添加适量707胶,涂层厚度在0.3-0.5mm;
(3) adding 707 glue to the first time fire retardant coating spray, the coating thickness is 0.3-0.5mm;
④涂层在24h后或表面基本干燥后可进行下遍施工,厚度在0.5-0.7mm,直接打到设计施工厚度。
(4) After 24 hours or after the surface is basically dry, the coating can be constructed again and again. The thickness is 0.5-0.7 mm, which is directly hit to the design and construction thickness.
施工过程中,要是遇到厚型钢结构防火涂料的粘结强度的问题,一定要冷静认真的分析造成粘结强度下降的原因,然后对症下药,找到最好的处理方案,保证厚型钢结构防火涂料施工的正常进行。
In the process of construction, if we encounter the problem of adhesive strength of thick steel structure fire retardant coatings, we must calmly and carefully analyze the reasons for the decline of adhesive strength, and then find the best treatment scheme to ensure the normal construction of thick steel structure fire retardant coatings.
