為什麼說环氧地坪施工环境要求高呢?
环氧地坪施工前必備的环境要求:环氧地坪是高質量、高要求的產品。為什麼說环氧地坪施工环境要求高呢?下面為大傢詳細解讀下。1、硬度:指塗裝基面的強度或混凝土基面的標號。塗裝基面的硬度從根本上決定塗層的使用年限、塗層的附著力和塗層使用效果。
The necessary environmental requirements before the construction of epoxy floor: epoxy floor is a product of high quality and high demand. Why does epoxy floor construction require high environmental requirements? The following is a detailed explanation for you. 1. Hardness: the strength of the base of the coating or the marking of the concrete base. The hardness of the coating base fundamentally determines the service life of the coating, the adhesion of the coating and the application effect of the coating.
2、平整度
2. Flatness
平整度:指塗裝基面平整與否的關鍵指標。
Smoothness refers to the key index of whether the base surface is smooth or not.
基面的平整度從根本上決定塗層的平整度,塗層的平整度直接影響到塗層的使用效果。
The smoothness of the base surface fundamentally determines the smoothness of the coating. The smoothness of the coating directly affects the application effect of the coating.
3、厚度
3. Thickness
厚度:指塗裝基面(結構層)最面上一層混凝土的厚度,不是指整個基層的厚度。
Thickness: refers to the thickness of the concrete layer on the most surface of the coated base (structural layer), not the thickness of the whole base.
厚度太薄,則容易脫層、空鼓。 要求面層的結構層的最小厚度為5CM的硬度C25以上。
The thickness is too thin, so it is easy to peel and hollowing. The minimum thickness of the structural layer required for the surface layer is 5CM and the hardness is above C25.
4、濕度
4. Humidity
濕度:指塗裝基面的含水率和塗裝环境的空氣濕度。
Humidity: refers to the moi彩色沥清地坪sture content of the coating base and the air humidity of the coating environment.
不同环氧地坪塗料對塗裝基面含水率要求不一致,环氧樹脂地坪塗料要求8%以下,甲基斌烯酸甲酯樹脂要求10%左右。
Different floor coatings have different requirements for the moisture content of the base surface. Epoxy floor coatings require less than 8% and methyl binoleate resin requires about 10%.
基面的含水率超標,則可能塗層出現水泡、起鼓、整片脫落等現象。
If the moisture content of the base surface exceeds the standard, there may be blisters, drums and shedding.
空氣中的含水率即濕度,可以用濕度計測量,一般环氧地坪漆施工時最好濕度在85%以下,但不要低於30% 。
The moisture content in the air is humidity, which can be measured by hygrometer. Generally, the best humidity for epoxy floor pai透水地坪nt construction is below 85%, but not below 30%.
5、溫度
5. Temperature
溫度:指塗裝环境的溫度,可以用溫度計測量。
Temperature: the temperature of the coating environment can be measured by thermometers.
不同種類的环氧地坪塗料對溫度的要求是不一致的。环氧要求在5℃以上,MMA要求-25℃以上。
Different types of floor coatings have different temperature requirements. The epoxy requirement is above 5 C, and the MMA requirement is above -25 C.
當然溫度太高也不能施工。,一者危險,二則固化太快不利於塗層性能展現。
Of course, the temperature is too high to work. One is dangerous, the other two is too fast curing.
6、潔凈度
6. Cleanliness
潔凈度:指除塗裝地坪塗料之外再無其他塗料或雜物包括灰塵、油污、水泥殘渣、其他油漆等。
Cleanliness: refers to the absence of other coatings or sundries, including dust, oil, cement residues, other paints, etc., except for floor coatings.
7、通風度
7. Ventilation
通風度:是塗裝环境通風與否的指標等 。
Ventilation degree is the index of ventilation in the coating environment.
因雙組份或多組分的地坪塗料固化時會產生熱量和水氣必須及時由流動空氣帶走,所以要求塗裝环境相對通風,但也不能太過通風。
Because the heat and moisture generated when two or more components of floor coating solidify must be taken away by the flowing air in time, the painting environment is required to be relatively ventilated, but not too ventilated.
8、粗糙度
8. Roughness
粗糙度:是指塗裝基面的表面的較小間距和微小峰谷的不平度。
Roughness: refers to the smaller distance between the base surface of the coating and the roughness of the tiny valley.
地面基面的兩波峰或波谷之間的局距離(波距)很小要求1mm一下,它屬於幾何形狀誤差。
The local distance (wave distance) between two peaks or troughs on the ground surface is very small, which requires 1 mm. It belongs to geometric error.
基面的粗糙度越小,則表面越光滑。塗層與基面的接觸面積比也就越小,塗層的附著力也會下降,反之則塗層的附著力將提高。
The smaller the roughness is, the more smooth the surface is. The smaller the contact area ratio between the coating and the substrate is, the lower the adhesion of the coating will be, and vice versa, the higher the adhesion of the coating will be.
