涂刷封閉底漆在多彩漆施工中的重要性

來源：http://www.wavc.cn 日期：2023-06-19 發布人：

封閉作用：

Sealing effect:

墻面一般使用水泥，而水泥通常會返堿，會在表面形成一層堿霜，出現成片成片的白色或結晶體或粉末狀等，造成花墻。出現泛堿的根本原因，大多數是底漆質量不過關或者是未使用底漆或者是膩子墻面堿性太強。封閉底漆可以起到封閉作用，緩解這種情況。

The walls are usually made of cement, which usually returns to alkali and forms a layer of alkali frost on the surface, resulting in flakes of white or crystalline or powdery materials, resulting in flower walls. The root cause of the occurrence of alkali efflorescence is mostly due to poor quality of the primer or the lack of use of the primer or the strong alkalinity of the putty wall. Sealing primer can play a sealing role and alleviate this situation.

保證吸水率一致：

Ensure consistent water absorption:

基底的含水率是建議高度注意的問題，尤其要注意同一墻面可能是不同材質，不同吸水率的基底材料，會導致外墻涂料終飾面出現水印或色差。

The moisture content of the substrate must be highly noted, especially when the same wall may be made of different materials with different water absorption rates, which can lead to watermarks or color differences in the final finish of the exterior wall coating.

安全可靠的預防方法是在施工前預先滿涂廠家生產的抗堿封閉底漆，使基底吸水率均勻一致。另外基底吸水率不一致，會導致涂層干燥時間不一致，吸收不均勻，也會導致出現色差。

A safe and reliable prevention method is to fully coat the alkali resistant sealing primer produced by a professional manufacturer before construction, so that the water absorption rate of the substrate is uniform and consistent. In addition, inconsistent substrate water absorption can lead to inconsistent coating drying time, uneven absorption, and color difference.

墻面牢固性：

Wall firmness:

質量不過關的膩子層時間不久會粉化，如果沒有底漆的保護，面層也會隨之出現粉化甚至脫落。封閉底漆能夠封固基底，使膩子層更加牢固，從而延長延長面層的壽命，提高施工質量。

The putty layer with poor quality will soon pulverize, and without the protection of the primer, the surface layer will also pulverize or even peel off. Sealing primer can seal the substrate, making the putty layer more firm, thereby extending the lifespan of the surface layer and improving construction quality.

底漆就有透明底漆、黑色底漆之分，那么，透明底漆和黑色底漆該如何選擇，這兩個顏色不同的底漆都有哪些區別呢？

Primers can be divided into transparent primer and black primer. So, how to choose between transparent primer and black primer, and what are the differences between these two different colored primers?

透明底漆和黑色底漆主要的不同在于墻面的分格，如果墻面分大格或者不分格的話，應該使用透明底漆，分大格的話后面還需用黑漆描線，而如果墻面是分小格的話則應該使用黑色底漆。

The main difference between transparent primer and black primer is the division of the wall. If the wall is divided into large or non divided compartments, transparent primer should be used. If the wall is divided into large compartments, black paint should be used to trace the lines. However, if the wall is divided into small compartments, black primer should be used.

透明底漆的綜合性能要好于有色底漆，簡單的了解，有色底漆是在透明底漆的基礎上添加了各種顏色的色漿，色漿本身只是起到改變顏色的作用，一定量的色漿計入底漆中，會降低產品本身的性能，因此，在項目選材時，盡可能規定施工單位要選用透明封閉底漆。

The comprehensive performance of transparent primer is better than that of colored primer. Simply understood, colored primer adds various colors of color paste on top of transparent primer, and the color paste itself only plays a role in changing the color. A certain amount of color paste is included in the primer, which will reduce the performance of the product itself. Therefore, when selecting materials for the project, it is necessary to specify that the construction unit should choose transparent sealing primer as much as possible.

Jinan Sealing Primer Construction Guide

1、在外墻底漆施工前，需要對外墻面進行一定的養護，要把墻面盡量整平，沒有太明顯的坑與凸起，更沒有裂縫之類的硬傷，把這些整的差不多之后，再來開工。

1. Before the construction of the exterior wall primer, it is necessary to maintain the external wall surface as much as possible. The wall surface should be leveled as much as possible, without obvious pits or protrusions, and there should be no hard injuries such as cracks. After these have been roughly leveled, work can begin again.

2、在外墻面上刷上底漆，底漆所具有的作用是相當重要的，它有良好的粘結能力，把墻面的堿性封閉掉，使外墻底漆施工時可以粘結的十分牢靠；還可以使灰層、膩子底融為一體，這大大提高了外墻的防水性能；而且還可以比較節省涂料，使涂料涂刷時比較均勻，后的效果也會很不錯。

2. Brush primer on the exterior wall surface, and the role of primer is quite important. It has strong bonding ability, sealing off the alkalinity of the wall surface, and making the exterior wall primer bond very firmly during construction; It can also integrate the gray layer and putty bottom, greatly improving the waterproof performance of the exterior wall; Moreover, it can also save paint, making the coating more uniform and achieving good results.

3、在這些做完之后才進行面漆的涂刷，不過在這之前要檢查一下底漆有沒有漏涂，上面有沒有被污染，在完成這些后才來進行道面漆的施工，面漆的涂刷也要做到均勻，方向一致。更多事項就來我們網站http://www.wavc.cn咨詢了解吧！

3. After these are completed, the topcoat should be applied. However, before doing so, it is necessary to check if the primer has been missed or contaminated. The first topcoat should only be applied after these are completed, and the topcoat should be applied evenly and in the same direction.
