Paint is the most important part of the home improvement project. It is also related to the environmental protection of home decoration. Choose a good paint, but there are many doorways. So what are the good techniques for buying paint? Look at it today and Xiaobian. See how the insider chooses paint?
Look at the packaging: consumers should carefully check the packaging when purchasing paint. Because polyester lacquer has large volatility, the product packaging should be well sealed, and there should be no leakage. Metal packaging should not show rust, otherwise it will indicate Poor sealing or long time; carefully check the date of manufacture and shelf life, first remove the inferior paint from the outer packaging.
Check the weight: According to industry insiders, different paint packaging specifications are different, and the weights are also different. Consumers can use the simple method to know the advantages and disadvantages: take each can and shake it, if it shakes, there is "å“—å“—" sound, indicating that the component is insufficient or volatile.
Look at the contents: It is generally not allowed to open the container when purchasing the paint, but the consumer should carefully check the paint contents before using it. The surface of the main paint should not be crust, the paint liquid is transparent, the color is uniform, and there is no impurity, and it should have good fluidity; the curing agent should be water white or light yellow transparent liquid, no delamination, no condensation, clear and transparent, no Impurity; thinner, scientific name "Tian Na Shui", commonly known as "banana water", clear, transparent, no impurities, good dilution.
Look at the constructability: After the quality of the paint is strictly in accordance with the requirements of the instructions, it should be delicate, uniform in gloss, uniform in color, suitable in viscosity, and have good construction tolerance.
Choose a business brand: When consumers buy paint, they should try to choose a reputable regular dealer to buy paint products with corresponding brands. If they find quality problems, they should respond or complain in time. Otherwise, after the completion, the quality of the paint is not good or construction. It is difficult to say clearly due to technical and environmental factors.
Water level sensor, alose called hydrostatic pressure level sensors, submersible level sensors, which are submersible level sensors used for measuring the level of liquids (including corrosive liquids) in deep tanks or water in reservoirs. It provide accuracy and reliability across a wide range of applications. Based on the principle that the measured liquid static pressure is proportional to the height of the liquid, the advanced isolation type diffusion silicon sensor or ceramic capacitive Pressure Sensor is used to convert the static pressure into electrical signals, and then through temperature compensation and linear correction, into standard electrical signals (generally 4-20mA/1-5VDC).
