Usually the wall is decorated. First, the first process is to do the grass layer treatment. This base treatment is actually plastering plaster . If the wall is to be beautifully decorated and durable, the construction process of plastering plaster is the key. Let's take a look at the four main points of the plastering construction process along with the decoration home decoration network.
Before plastering the plaster, in order to make the gypsum bond firmly to the bottom wall surface, to prevent the phenomenon of empty drums, falling off, etc., it is necessary to clean the dust and debris on the bottom surface, and to fix or level the unevenness. . The last thing is to keep the wall in a wet state, but you can't directly sprinkle it on it.
Point 2: Proportionate preparation of ashes
Gypsum sand ratio: powder 1: water 0.18-0.22
Gypsum preparation: Pour a certain amount of water into the mixing tank, then pour the ash into the ash for 3-5 minutes until the desired viscosity is reached, then stop for about 5 minutes and then stir for the second time. After stirring for 3-5 minutes, it can be taken for construction.
Point three: wall flour brush plaster
1. Bottoming: the first step is to put the cake and fill the ribs, and the wall is looking for Zhou Zheng; the second step is plastering, the thickness is between 5mm-8mm; the third step is to scrape the ash layer and compact it; the fourth step Press the hand to check if the wall is smooth and smooth.
2. The order of plastering is to first wipe the cylinder surface and the brick wall surface. After the two ash layers are solidified, the joints of the two are plastered to form a expansion joint.
3, the cover, that is, plastering the surface of the gray layer. Generally, it is painted twice, and the thickness is about 2mm per pass. The first pass is used to fill the unevenness and increase the adhesion of the wall. The second pass is to calender, making the wall smoother, brighter and flatter. The second pass should be started 30 minutes after the first pass , and the number of calenders should be more than three times.
1. The preparation of the ash material can only be matched by the weight ratio and cannot be matched by the volume ratio.
2, because the initial setting time of gypsum mortar can only be maintained for about 30min, so do not make too much ash material each time to avoid waste.
3, layered plaster, each layer thickness is less than 8mm.
4. Vertical plastering at the corner of the corner.
5. The temperature is below 5 degrees below zero and it is not suitable for construction.
6. Close the doors and windows with curtains or other objects to prevent air convection from damaging the paint layer.
The above is the introduction of the construction process of the plastering plaster in the decoration home decoration network. After reading it, I believe that you will be able to help you decorate your own wall beautifully and durable.

ZG High Efficiency Slurry Pump
Naipu ZG series pumps are cantilevered,horizontal,centrifugal slurry pumps. They are used international advanced solid-liquid two-phase flow theory and were designed using the Minimum-Wear Principle. The flow parts of this pumps are suitable for the flow of state media for it's set shape, which reduces hydraulic loss of eddy and impact, both in pump and along the pipeline; so reduced friction of flow parts, lower noise and vibration of the pump translates into improved hydraulic efficiency.
Typical Applications---
Electric Power
Constructional Material
Mine Coal
Coal washing
Sand Reclamation
Sugar Beet
