The manufacturing process of ceramic night lights is mainly composed of soil selection, humidification and stirring, solidification and molding, hollowing treatment, high temperature calcination, from affixing the pattern paper, secondary heating, testing and packaging. The main reference when purchasing earth is its light transmission. The better the light transmission from the ground, the brighter the lit night light lampshade. Put the purchased soil into a soil mixer and add an appropriate amount of water to stir to make the soil finer. , uniform and smooth, pour it into the mold to solidify, take it out for surface treatment and digging, then put it in a high temperature oven to burn. After burning and cooling, the basic green tire will be formed. the processing steps after the formation of the green tire mainly consist ofent to apply patterns on paper and paint, flower paper refers to the gluing of pre-designed patterned paper onto different shapes of blanks, and the pattern of the flower paper is permanently printed on the lampshade after a secondary heating. . The colorful painting is made by hand and treated with craft paint. After the painted craft paint is diluted with thinner to a certain ratio, it is then manually painted according to the designed pattern with a special hand-painted pen and then left. wait for the craft paint to dry. After that, the painting process is completed.
Lithium batteries are better than nickel-metal hydride batteries. 1. Volume: Rechargeable lithium batteries are smaller (relatively), lighter, have a low self-discharge rate, and have no memory effect than ordinary nickel batteries. Metal hydride batteries. Advantages, widely usefulized in many new mobile devices. The batteries of cell phones, laptops, PDAs and other mobile devices that we usually use have gradually been replaced by lithium batteries.
2. Electricity: Lithium batteries have high specific energy and are compact; the voltage of a single lithium battery is three times that of a nickel-metal hydride battery; there is no memory effect and can be charged; at any time.
3. Charging method: The charging requirements of lithium batteries are different from those of nickel-cadmium/nickel-metal hydride batteries. The voltage of a rechargeable lithium battery cell is 3.6V (some battery packs may be). nominally 3.7 V). As the power supply is fully charged, the voltage of the lithium battery will slowly increase, which also indicates whetherthe lithium battery is full. Typically, manufacturers recommend a charging shutdown voltage of 4.2 V (for a single-cell lithium battery). . Lithium batteries are generally charged using the voltage limiting and current limiting method. If a friend wants to charge the lithium battery independently, it should be noted that its charging method is different from the constant current charging method used for ordinary nickel-metal hydride batteries. Nickel-cadmium/cadmium charging methods cannot be used. Charger for NiMH batteries.
