Guizhou stone is composed of natural sand as a natural coating material made of natural stone, is feeling. Able to make many three-dimensional drawings, there is a natural sense of happiness for me. Its decorative function is similar to marble and granite. It has natural and real natural color and gives people elegant, harmonious and solemn beauty. The real stone paint has the characteristics of waterproof, fireproof, acid and alkali, innocuous and harmless, and does not fade. It can help to obstruct the corrosion of the outside environment to the building, and improve the service life of the building. It has good adhesion and freeze-thaw, so it is suitable for application in cold area.
First, control from the source
Different places, different mines and even the same mine in the color of colored sand have different colors, some are not general large, so we enter the sand into place as far as possible, and sand requires the manufacturers to mix well (many large quantities of sand manufacturers supply this service), sand come in The post demand check includes whether the sand color is the same, and whether each bag of sand components is the same. If color is not common, the most original method is to mix technology. Put the sand on the ground and mix it up, mix it evenly, and then pack it, each bag should have the same weight. The type and quantity of the emulsion also have a certain influence on the color of the true stone paint, so it is possible to use the same kind of the same batch of emulsion as much as possible in the same residential area or larger building, so that the color difference can be manipulated well. Every batch of data comes in through a small test. After determining the proportion of sand, we will make large production. As the color of each batch of sand more or less, there are certain errors, as long as the test can be further determined by the test, so that there is a good number of things to avoid unnecessary trouble and loss.
Two. Manipulate in production
Stone production needs of mass production, so to improve production capacity of various cylinder. The bigger the capacity of single cylinder, the easier the color difference is. The same number of lacquer production batch is less, the color is small. In the production of real stone paint, it is necessary to manipulate the production process. It advocates that water, emulsion and all kinds of additives are made into real stone lacquer slurry, and then the viscosity of the slurry is adjusted to take part in the mixture of the stone and the kettle, and then all kinds of sand in the formula are joined. The principle of adding sand is to take the finest sand powder first, then add coarse sand, add less amount first and add large amount later.
Add the sand, sand and。 And the color sand should leave the allowance, can not be added once, because the large production and test small test is a little distance, especially fine sand powder, can be said to be used for color adjustment, the more to leave the allowance。 Otherwise, it is difficult to add more, filled with white sand do not know how much to fill, and even put out some point out, and fill the white sand, and add slurry, that is, delay time and waste material, it may be said to have a lot of money and money。 The speed of the real stone paint mixing kettle is limited。 It is advocated that when the real stone paint mixing kettle takes part in the slurry, it will add some color to the sand, and others, such as latex and auxiliaries, will not be added。 A cauldron of true stone paint in the future is best for a period of time, because the sand powder has been rich in color through a period of time, so the color of the true stone paint is stable, so there will be no change。
Three。 Control from construction
The quality of the construction is very important for the real stone paint。 The decorative effect of the true stone paint is directly reflected in the construction。 It can be said that the most important part of the construction is to manipulate the color difference of the true stone lacquer。 The same side of the wall as far as possible with the same batch of lacquer, to ensure the uniformity of color information。 When spraying, the nozzle and the bottom should adhere to the straight condition, from left to right, and then from right to left。 The nozzle is suitable to the wall 30mm。 When the nozzle is finally formed, the nozzle should be sprayed in one direction to avoid joint and flower。 When the gun is sprayed at the same time, the same type of "gun plug" should be used, and the hand gestures and spraying speed of each gunner should be common to ensure that the shape of the true stone paint is basically common in appearance, which ensures the common color of the true stone paint。 In order to reduce jet loss and spray angle, it can be sprayed directly from the top to the bottom and then horizontally spray。 When spraying the corner, do not spray directly on the corner, so that the coating on both ends of the corner will be thin, while the outer coating on the corner is too thick。 They should be directly sprayed from the top and bottom from the two ends of the corner, and then spray along the horizontal direction。 When spraying directly, the nozzle is far away from the top of the corner, so that the spray just happens at the top of the corner, and there will be no drop。
