腻子打磨后有划痕该怎么处理?

来源: 日期:2021-10-18 发布人:juyehe

腻子的主要作用虽然是找平,但只是批刮腻子的话,仅仅是做了一半的找平工作,另外的一半,也是决定 效果的一半, 要通过打磨来解决。这也是做墙面打磨的主要功能。

Although the main function of putty is leveling, if only putty is applied, only half of the leveling work has been done, and the other half is also the half that determines the effect, which should be solved by grinding. This is also the main function of wall grinding.
腻子批刮过程中,难免会出现一些微小的瑕疵,比如腻子交界处的接茬、局部批刮过薄或过厚留下的痕迹、墙面吸水造成的针孔等,这些瑕疵也是可以通过墙面打磨来解决的。
In the process of putty scraping, it is inevitable that some minor defects will appear, such as the connection at the putty junction, the traces left by local putty scraping too thin or too thick, pinholes caused by water absorption on the wall, etc. these defects can also be solved by wall polishing.
整体打磨后的腻子表面结构更加均匀一致,可以加强乳胶漆的表现效果,而且避免了因表面结构的差异可能引发的一些问题(如色漆局部色差等)。
The putty surface structure after overall polishing is more uniform and consistent, which can strengthen the performance effect of emulsion paint and avoid some problems that may be caused by the difference of surface structure (such as local color difference of color paint, etc.).
墙面打磨用什么工具?
What tools are used for wall grinding?
灯泡:为了能随时观察墙面平整度,打磨时,无论白天黑夜,工人一般都要在手里拿着一个灯泡。灯泡的瓦数一般都在200瓦以上,这样即使白天也能很好的观察到墙面的平整情况。
Light bulb: in order to observe the flatness of the wall at any time, workers generally hold a light bulb in their hands during grinding, day and night. The wattage of the bulb is generally more than 200 watts, so that the flatness of the wall can be well observed even during the day.
砂纸:打磨腻子的砂纸选择是大家比较关心的问题,这里系统讲一下。墙面打磨中常见的砂纸目数(每英寸的砂粒数)有80、120、180、240、320、400、600。其中80、120可以归为粗砂纸,180、240为中等,320以上为细砂纸。砂纸过粗,容易导致出现划痕,砂纸过细,很难打磨得平整,所以墙面砂纸的选择,并不是越粗越好,也不是越细越好,而是与墙面腻子相匹配为宜。
Sandpaper: the choice of sandpaper for polishing putty is a matter of concern. Here is a systematic discussion. There are 80, 120, 180, 240, 320, 400 and 600 sand paper meshes (sand grains per inch) commonly used in wall grinding. Among them, 80 and 120 can be classified as coarse sandpaper, 180 and 240 are medium, and more than 320 are fine sandpaper. If the sandpaper is too thick, it is easy to cause scratches. If the sandpaper is too thin, it is difficult to polish it flat. Therefore, the choice of wall sandpaper is not the coarser the better, nor the finer the better, but should match with wall putty.
实际操作中,首先要以能把平整度做好为目标,墙面打磨多用240、320先进行试打,如果打磨起来不是很吃力,可以把平整度做得很好,那就继续;如果感觉打磨很吃力,那就换用低目数的粗砂纸再进行试打。在保证了墙面平整度的前提下,如果一遍使用了粗砂纸,一般整体或局部还需要用细砂纸再打磨一遍,以消除粗砂纸留下的划痕,并且让墙面更加细致。
In actual operation, first of all, we should aim to do a good job in flatness. Wall polishing is mostly used. 240 and 320 should be tested first. If it is not very difficult to polish, we can do a good job in flatness, then continue; If you find it difficult to polish, use low mesh coarse sandpaper for trial beating. On the premise of ensuring the flatness of the wall, if coarse sandpaper is used once, it is generally necessary to polish the whole or part with fine sandpaper again to eliminate the scratches left by coarse sandpaper and make the wall more detailed.
按腻子质量来说。非耐水腻子由于表面结构疏松,所以比较容易打磨,一般都用240、320或更高的砂纸来打,不过由于大多数非耐水腻子质量都比较差,粉料本身的目数普遍较低,所以即便用高目的砂纸打磨,也很难打出非常细致的感觉。
According to the quality of putty. Due to the loose surface structure, the non water resistant putty is easy to polish. Generally, 240, 320 or higher sandpaper is used to polish it. However, because the quality of most non water resistant putty is relatively poor and the mesh of powder itself is generally low, it is difficult to polish it with High-Purpose sandpaper.
耐水腻子表面结构相对牢固,打磨要比非耐水腻子费力很多,尤其是一些高强型的耐水腻子,如果等到腻子完全干透后再打磨,就很困难了,这时候就需要先用粗砂纸把平整度做好,然后再用细砂纸打二遍,以求更好的效果。
The surface structure of water-resistant putty is relatively firm, and polishing is much more laborious than non water-resistant putty, especially some high-strength water-resistant putty. It is very difficult to polish until the putty is completely dry. At this time, it is necessary to do a good job of flatness with coarse sandpaper, and then hit it twice with fine sandpaper, so as to achieve better results.
