Heilongjiang putty powderThe cause of the pinhole
Cause:
1, the pinhole is a normal phenomenon。Because the putty powder layer is thicker when the road is scraped, and it should not be flat, the adhesion of the second road will be affected after the flat road is closed。Two and three pinholes will generally appear in some of the more uneven places on the wall, because the uneven places eat more material, more slowly dry, scraper is more difficult to compact the concave place putty powder layer, which will produce some pinhole phenomenon。
2, due to the lack of light during construction, the construction personnel will ignore some relatively small pinholes on the wall during construction, and fail to smooth out some pinholes in time。
Treatment method:
1, the uneven wall should be made up as far as possible during the construction of the road (because the road produces fine pinholes will not affect the normal construction of the second road), which is conducive to the second and third putty powder layer when the batch is scraped, reducing the generation of pinholes。
2, in the construction should pay attention to the light, if the weather is not enough light or the light in the evening from bright to dark, should be carried out with the help of lighting equipment, to avoid construction errors caused by man-made pinhole problems。
Note: The high viscosity of putty powder or relatively slow drying will also produce some pinhole phenomenon, should pay attention to the rationality of the product formula。
