After cutting a few chips, mortar density is getting lower and lower
There are a lot of things that could happen1 lubricant is not qualified2 too many bubbles in the recycle bin3 mortar selection4, the operation speed is too fast5 wafer density is not uniform (the lowest possible)Try not to contact
PEG water absorption is very strong, as long as the air humidity is slightly higher, then did not cut the water content of a mortar on the rise, as well as the viscosity of mortar and mortar temperature is related to the temperature difference, the viscosity of mortar to a difference of about 10
Iron powder and silica fume more and more, the density should be more and more big, unless it is your water content is higher and higher
