3 yuan kg really stone paint is how to

3 yuan a kilo of really stone paint is made of how: 'every day, customers call us, ask how much we wall really stone paint per kilogram? ”？ As a result, when we heard our price, we say it is too high. We also said that others family only 3 yuan per kilogram. Ok, let me tell you how to do 3 yuan/kg really stone paint the exterior wall of the following. Why are they true stone lacquer is much cheaper than us? There is only one answer: - — Using cheap inferior raw materials! 1. Use the inferior color sand; Poor colour sand, about 0 per kilogram. 3 - 0. 5 yuan, hardness, Silica content) Is the most important basis to measure the color sand quality. Color sand, the better the more expensive, the higher the hardness. On the contrary, colored sand the worse, the lower the hardness. Really stone paint production is a high-speed mixing process. Colour sand will produce very big friction each other. Inferior color sand hardness is low. In the process of production, due to the effect of friction force, can produce a greater degree of pulverization, color sand becomes colored powder. The final coating effect, the sand is very fuzzy, lack luster and texture, high quality colour sand, in high speed mixing process, due to the high hardness, the friction resistance, not easy pulverization, the final coating effects, color sand is very clear, rich texture and luster. If paint colorful, 3 yuan per kilogram really stone paint can only add color paste, because the price of light color high temperature calcination sand per kg in 2. 5 - 3. 5 yuan between. 2. Using bad emulsion; Emulsion is really stone paint film forming material, its quality directly decides the performance of the coating. For example, Yellow degeneration resistance, water resistance and service life, etc. ) 。 ) Poor, emulsion and emulsion with high quality uv test in the laboratory. Bad emulsion anti-uv ability is very poor, after the sun will soon turn yellow. Water resistance is one of the most important indicator of evaluation of emulsion. Bad emulsion was very poor resistance to water, the water will become white. Really stone paint, emulsion content is extremely low and the poor. In order to reduce costs, the content of the emulsion in general is relatively low, in the process of spray splashing, waste is serious, significantly increase the amount coating. Generally speaking, the normal dosage of really stone paint for 3 - per square metre Low grade 4 kilograms, and low-cost true stone lacquer is often more than 4 kilograms per square meter, or even because of waste, loss and achieve 5 kg. 3. Use the inferior additive; Really stone paint USES a small amount of additive, but it decides the stability of the formulation system. For the poor quality of additive products placed after period of time will happen serious stratification.
