1.Burning in cylinder
●Cause: the temperature is high
●Solution:The curing temperature of resin can be reduced by reducing curing ratio or increasing filling component.It can also be made in two or more times to reduce the heating temperature.
●Cause: The dosage of cobalt water and methyl ethyl ketone is too high, resulting in the high curing temperature of the resin.
●Solution:Adjust the curing ratio
2.The resin corrodes the plates
●Cause: Plate is lower hardness or plate is thinner
●Solution:Replace the plate with a higher hardness or sweep a layer of resin at the thinner diamond Angle, to play the role of protective layer
3.Product surface sticky
●Cause: incomplete curing of resin
●Solution: increase the ratio of resin curing, especially in cold or wet weather.
●Cause: stone powder, fiber and other auxiliary materials are affected by moisture
●Solution: for the storage of auxiliary materials, make sure they are not wet or damp. When the weather is humid, the material can be baked before use.
