如今外墻涂裝大多采用外墻涂料進(jìn)行裝飾郎闹，抗堿封閉底漆很大的特點(diǎn)就是對混凝土有超強(qiáng)的附著力茫叭，防止水的滲透酬屉，抗堿隔離作用，對基層的堿分能有效隔離揍愁，防止堿分的滲出破壞涂層。對疏松粉化的基底進(jìn)行補(bǔ)強(qiáng)作用杀饵，加固基底莽囤。外墻抗堿封閉底漆到底有多重要？

Nowadays, the exterior wall coating is mostly used for decoration. The great feature of the alkali resistant sealing primer is that it has super adhesion to the concrete, prevents water penetration, and has the effect of alkali resistance isolation. It can effectively isolate the alkali content of the base layer and prevent the alkali content from seeping out and damaging the coating. Reinforce the loose and powdered base. How important is alkali-resistant sealing primer for exterior wall?

1切距、封閉作用：墻面一般使用水泥朽缎，而水泥通常會返堿，會在表面形成一層堿霜谜悟，出現(xiàn)成片成片的白色或結(jié)晶體或粉末狀等话肖，造成花墻。出現(xiàn)泛堿的根本原因，大都是底漆質(zhì)量不過關(guān)或者是未使用底漆或者是膩?zhàn)訅γ鎵A性太強(qiáng)最筒。其他如發(fā)生的變黃或顏色改變也大多與此有關(guān)贺氓。封閉底漆可以起到封閉作用，緩解這種情況床蜘。

1. Sealing effect: The wall is usually made of cement, and the cement will usually be re-alkali, which will form a layer of alkali frost on the surface, and flakes of white or crystal or powder will appear, resulting in flower wall. The basic reason for the occurrence of alkali is that the quality of the primer is poor, or the primer is not used, or the putty wall is too alkaline. Most of the other yellowing or color changes are also related to this. The sealing primer can play a sealing role and alleviate this situation.

2猫单、保證吸水率一致：基底的含水率是必須高度注意的問題，尤其要注意同一墻面可能是不同材質(zhì)玛呐，不同吸水率的基底材料朗猖，會導(dǎo)致外墻涂料很終飾面出現(xiàn)水印或色差，安全可靠的預(yù)防方法是在施工前預(yù)先滿涂廠家生產(chǎn)的抗堿封閉底漆冻咆，使基底吸水率均勻一致殿膏。另外基底吸水率不一致，會導(dǎo)致涂層干燥時間不一致炮家，吸收不均勻尘箫，也會導(dǎo)致出現(xiàn)色差。

2. Ensure the consistency of water absorption: the water content of the base must be paid high attention, especially the same wall may be made of different materials, and the base materials with different water absorption will lead to watermarks or color differences in the final finish of the exterior wall coating. The safe and reliable prevention method is to fully coat the alkali resistant sealing primer produced by professional manufacturers before construction to make the water absorption of the base uniform. In addition, the inconsistent water absorption of the substrate will lead to inconsistent drying time of the coating, uneven absorption and color difference.

3睡誉、墻面牢固性：質(zhì)量不過關(guān)的膩?zhàn)訉訒r間不久會粉化畏琢，如果沒有底漆的保護(hù)，面層也會隨之出現(xiàn)粉化甚至脫落伤很。底漆能夠封固基底虐欲，使膩?zhàn)訉痈永喂蹋瑥亩娱L延長面層的壽命肺樟，提高施工質(zhì)量檐春。

3. Wall firmness: The putty layer with poor quality will pulverize soon. If there is no primer protection, the surface layer will also pulverize or even fall off. The primer can seal the base and make the putty layer more firm, thus extending the service life of the surface layer and improving the construction quality.

作為用戶要清楚了解，透明底漆的綜合性能要好于有色底漆么伯，簡單的了解疟暖，有色底漆是在透明底漆的基礎(chǔ)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田柔，一定量的色漿計入底漆中俐巴，會降低產(chǎn)品本身的性能，因此硬爆，在項目選材時欣舵，盡可能規(guī)定施工單位要選用透明封閉底漆。更多產(chǎn)品事項可以隨時聯(lián)系我們http://m.bjtsdc.com了解缀磕！

As a user, you should clearly understand that the comprehensive performance of transparent primer is better than that of colored primer. Simply understand that colored primer is based on transparent primer with various color pastes added. The color pastes themselves only play a role in changing the color. A certain amount of color pastes will be included in the primer, which will reduce the performance of the product itself. Therefore, when selecting materials for the project, it is required that the construction unit should select transparent sealing primer as far as possible.
