Anonymous users2024-01-23The manufacturing process of ceramic night light is mainly divided into soil purchase, humidification and stirring, solidification molding, hollowing processing, high-temperature calcination, sticking pattern paper, secondary heating, testing and packaging and other steps. The purchase of soil mainly refers to light transmittance, the better the light transmittance, the more transparent the fired night light lampshade, put the purchased soil into the soil mixer, add the appropriate amount of water to stir, make the soil thinner, uniform and smooth, pour into the mold to solidify and form, take out the surface treatment and hollowing, and then put it into the high-temperature furnace to burn, after burning and cooling, the basic billet tire is formed, and the processing steps after the formation of the billet tire are mainly pasted pattern flower paper and color painting, Flower paper refers to pasting pre-designed pattern paper on different forms of billet tires, and the pattern of the flower paper is permanently printed on the lampshade after secondary heating. Painting is made by hand-depicting the process of paint, the process paint of the painting is diluted according to a certain proportion by the use of thinner, and then by the manual according to the designed pattern, painted with a special hand-painted pen, and then placed to wait for the process paint to dry, the painting process is completed.

Anonymous users2024-01-22Just buy a small solar panel, get a small battery, and then get some LED lights, and then install it on the OK, and then make a control circuit by yourself OK, if you really need to come to me, I provide technical support, you find your own way to get it, it's very simple!! Or just buy one!!
The price of balcony wall-mounted solar energy is generally high, and the price of the brand is generally around 5000-8000 yuan. The collectors of wall-mounted solar energy do not go out of the tube (no pipe bursting, safe operation), and the operation mode of the water tank is under pressure, which is much higher than the cost of ordinary falling water solar energy. The selling price is also much higher.
The advantage of using copper coil is antifreeze, the copper coil is placed in the water tank and connected to the collector, and the antifreeze is installed inside, which is a double-circuit system.
First of all, in general, when we install solar energy, the collector surface is about 5 degrees west due south. You can compare it according to this ordinary standard, secondly, there is solar energy that can be installed on the balcony, but it is not a solar water heater that integrates a vacuum tube and a solar water tank.
Wall-mounted, whether you need electric heating depends on your local climate. Of course, it is good, but it also costs electricity, so it is recommended to connect a small electric water heater.
Here's how to add it:
1. Determine the minimum air temperature for the local area, and on the basis of the minimum temperature, float down 5 10 and choose antifreeze. If the local minimum temperature is -15, choose the freezing point of antifreeze, which cannot be higher than -20, so as not to cause the antifreeze to become viscous and affect the use of extreme weather. >>>More
