首先给大家科普一个名词“涂布率”——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。不同品牌厂家生产的油漆，理论涂布率不尽相同，需根据产品说明书区别对待。

First of all, a noun "coating rate" - the surface of a completely smooth, smooth and non - pore glass, poured a liter of paint to form the area covered by the specified thickness of the dry film. Different brands of paint, the theoretical coating rate is not the same, need to be treated according to the product manual.

理论涂布率=固体体积含量x10/干膜厚度（微米） 单位：㎡/升

Theoretical coating rate = solid volume content x10/ dry film thickness (micron) unit: L / L

油漆损耗大致有以下几种：

There are several kinds of paint loss as follows:

一、与构件表面积的处理方式有关，经过抛丸或喷砂处理后，钢板表面形成了大小深浅不一的坑，坑底的油漆就变成了损耗。

First, it is related to the processing mode of the surface area of the component. After the shot blasting or sand blasting treatment, the surface of the steel plate forms a deep and shallow pit, and the paint at the bottom becomes a loss.

二、与施工方法有关，如滚涂损耗约5%、无气喷涂损耗约10%-20%、有空气喷涂50%以上，以及尽量避免有风的施工环境等。

Two, it is related to the construction method, such as rolling loss about 5%, gas spray loss about 10%-20%, air spraying more than 50%, as well as avoiding the wind of the construction environment.

三、与工人操作水平有关，如喷涂后构件油漆层部分超厚、部分厚度不足，返工造成的损耗。四、与需要喷涂的构件形式有关，如角钢桁架和H型钢吊车梁，前者损耗比后者就大得多。

Three. It is related to the operation level of the workers, such as the excessive thickness of the paint layer after spraying, the inadequate thickness of part, and the loss caused by rework. Four, related to the form of components needed to spray, such as angle truss and H steel crane girder, the former is much larger than the latter.

综上所述，损耗的不定因素很多，正常情况下按照40%-60%考虑即可，特殊情况另当别论。下面通过举例来详细阐述钢结构油漆用量的理论算法：

To sum up, there are many uncertain factors of loss, which can be considered according to 40%-60% in normal circumstances. The following is a detailed illustration of the theoretical algorithm for the amount of paint used in steel structures by example.

举例：现有1吨H型钢（表面积28㎡），表面处理是抛丸除锈，采用无气喷涂工艺，底漆是环氧富锌漆，固体含量54%，干膜厚度80微米，比重1.79kg/升，单价是42元/升（可以换算成kg，42/1.79=23.46元/kg）；稀释剂单价20元/kg，按油漆量的10%考虑。问1吨钢构折合环氧富锌漆为多少元每吨？

For example: 1 tons of H steel (surface area 28), surface treatment is shot blasting and rust removal, using no gas spray technology, primer is epoxy zinc rich paint, solid content 54%, dry film thickness 80 microns, the proportion of 1.79kg/ liter, the unit price is 42 yuan / liter (can be converted into kg, 42/1.79=23.46 /kg); diluent unit price 20 yuan /kg, according to the amount of paint. The 10% consideration. How much is the 1 ton steel structure equivalent to epoxy zinc rich paint?

1、计算理论涂布率=54*10/80=6.75㎡/升

1. Calculation of theoretical coating rate =54*10/80=6.75 / liter

2、根据油漆比重，计算一平方钢构表面积，80微米的干膜厚度，需要多少公斤的油漆：1.79/6.75=0.265kg/㎡

2. According to the specific gravity of paint, how many kilograms of paint should be calculated on the surface area of a square steel and the thickness of the dry film of 80 microns: 1.79/6.75=0.265kg/

3、计取50%损耗，1吨钢构需要的油漆重量：28*0.265*（1+50%）=11.13kg

3, take 50% loss, 1 tons steel structure required paint weight: 28*0.265* (1+50%) =11.13kg

4、稀释剂用量：11.13*10%=1.11kg

4. The amount of diluent: 11.13*10%=1.11kg

5、1吨钢构底漆价格为：11.13*23.46+1.11*20=283.31元

5, 1 ton steel primer price is: 11.13*23.46+1.11*20=283.31 yuan.
