Method for processing two-in-one 4B lead core

[0013] First prepare the main ingredients: talcum powder with a fineness of 2000 meshes, and 100 kg of wet clay as clay. Put 20kg of cosmetic grade white oil, 36kg of water-soluble wax, 25kg of polymer wax, 10kg of pigment, 5kg of titanium dioxide, and 4kg of peach gum in 100kg of main ingredients; stir the above materials evenly, knead for 3 hours at a temperature of 35 degrees Celsius, and then use The rolling machine presses it into thin slices with a thickness of 8.0 mm and a moisture content of 13, and then stores them for 72 hours. Finally, a Φ7.0 two-in-one 4B lead core is pressed out by a core press machine, and cooled in cold water to harden for use as a spare.
