主次钢结构都是根据防腐的要求来打砂油漆的，油漆的用量很大程度和干膜厚度有关的，与施工方法和涂装系统也有关系（喷涂要比手工刷的损耗率），以下数据是理论涂布率（仅供参考），实际用量乘上1.5-1.8的系数：

The main and secondary steel structures are made of sand and paint according to the requirements of anticorrosion. The amount of paint is largely related to the thickness of the dry film. It is also related to the construction method and the coating system. The following data are the theoretical coating rate (for reference only), the actual amount of 1.5-1.8 is multiplied by the coefficient of:

75微米厚度的，大约8.5平方米/升；

The thickness of 75 microns is about 8.5 square meters / liter;

125微米厚度的，大约6.5平方米/升；

The thickness of 125 microns is about 6.5 square meters / liter;

200微米厚度的，大约4平方米/升。

The thickness of 200 microns is about 4 square meters / liter.

      一般是使用容积单位来衡量的。

It is usually measured in units of volume.

      油漆说明书里有个理论涂布率，就是涂1平方米100um（或者是50um等等自己可以换算）用多少L油漆。比如这个数是X%

There is a theoretical coating rate in the paint manual, that is, how much L paint is coated with 1 square meters 100um (or 50um, etc.). For example, this number is X%

那么油漆用量=x%*25000*油漆厚度/100

Then the amount of paint =x%*25000* paint thickness /100

这个结果之后你再乘以一个损耗系数，比如1.3一般这个与施工的设备有关系。

After this result, you multiplied by a loss coefficient, such as 1.3, which is generally related to the construction equipment.

       在钢结构上焊缝的净重量是钢构件的1.5～2％左右。然后根据这个来提焊条，由于是净重量所以焊条重量有些增加，加上留下的焊条头，和药皮的重量，一般需要焊条重量的是1.8～2.2倍。点击☞工程资料免费下载

The net weight of welded joints on steel structures is about 1.5 ~ 2% of steel structures. Then according to this, the welding rod is raised. Because of the net weight, the weight of the electrode is increased, and the weight of the electrode and the weight of the skin are 1.8 to 2.2 times as much as the weight of the electrode.

        油漆的理论涂布率和实际涂布率计算公式

Formula for theoretical coating rate and actual coating rate of paint

        在完全光滑平整且无毛孔的玻璃表面，倒上一升油漆，形成规定的干膜厚度后所覆盖的面积，就叫该油漆的理论涂布率。

The area covered by the specified thickness of the dry film is called the theoretical coating rate of the paint.

 

It

理论涂布率=固体体积含量*10/干膜厚度（微米） （米²/升）

Theoretical coating rate = solid volume content *10/ dry film thickness (micron) (M / L)

     

     

实际工程施工时，因施工工件表面形状，要求的漆膜厚度，施工方法，工人技术，施工环境条件，天气等等各种因素的影响，油漆的实际使用量一定大于以施工面积除以理论涂布率计算出来的“理论使用量”。

In actual engineering construction, the actual use amount of the paint must be more than the theoretical use calculated by the construction area divided by the theoretical coating rate because of the surface shape of the work piece, the required film thickness, the construction method, the workers' technology, the construction environment conditions, the weather and so on.

油漆实际使用量/理论使用量(该比值定义为“损耗系数”CF。)

The actual usage of paint / theoretical usage (the ratio is defined as "loss coefficient" CF). )

工程油漆实际用量 = 施工面积/实际涂布率=施工面积*CF/理论涂布率=  理论使用量× CF

Actual dosage of Engineering paint = = construction area / actual coating rate = construction area *CF/ theoretical coating rate = theoretical usage amount * * CF

        工件表面粗糙度造成的油漆损耗

Paint loss caused by surface roughness of workpieces

        在经过喷射处理的表面涂漆时，钢板波峰处的膜厚要小于波谷处的膜厚，为满足波峰处的防腐厚度要求（避免点蚀），波谷的坑洼中所“藏”的油漆就相当于被损耗了，此即“钢板粗糙度消耗损失”。

The film thickness at the peak in the wave peak is less than the thickness of the film in the wave valley. In order to meet the requirement of the anticorrosion thickness at the peak (avoid pitting), the "hidden" paint in the trough of the trough is equivalent to the loss, that is, "the loss of the roughness of the steel plate".
