Simply Analyze the Effect of Filler on the Performance of Printing Paper
The addition of fillers to printing paper can improve the printability of the paper, such as increased paper whiteness, smoothness, opacity, and stiffness. Improves the affinity, softness, and stability of paper for ink, which helps improve the quality of prints. Of course, too much filler added to the paper also brings some undesirable effects. The main manifestations are the decrease of the paper strength and the decrease of the sizing effect. In the printing, the phenomenon of falling powder...

Effect of Filler on Printing Paper
Filling in printing is to make the paper obtain certain properties such as whiteness, opacity, smoothness, etc. At the same time, the addition of filler makes the internal voids of the paper smaller and thinner, thereby increasing the ink absorption of the paper and making the ink absorption variable. uniform. The most common fillers for printing paper are inorganic fillers, talc, clay, titanium dioxide, and calcium carbonate. Among them, titanium dioxide is an expensive and high-quality...
Look at the fuel filler to determine engine failure
Black smoke If the engine starts, black smoke comes out of the oil filler port and is accompanied by a knocking sound, indicating that the cylinder liner and piston are worn, the clearance is too large, or the piston ring has leaked. After starting the white smoke engine, the oil filling port will emit white mist rhythmically, which is a precursor to burning tiles. The high temperatures caused by the dry friction before burning tiles cause the temperature of the local oil to rise sharply, and...
