Abstract
A manufacturing apparatus of a coating film product rolls a mixture coating material by a first roll and transfers the mixture coating material to a coated object in motion to thereby manufacture the coating film product. An arithmetic average roughness Ra on a roll surface of the first roll is higher than a value 0.05 times of a particle size “d10” in which an integrated distribution of particle sizes of particles included in the mixture coating material is 10% and lower than a value 20 times a particle size “d90” in which an integrated distribution is 90%.
Claims1
A manufacturing apparatus of a coating film product, comprising:
- a coating material supply hopper for supplying a coating film material including particles and having a volume water content of 20 volume % or more to 65 volume % or less;
- and
- first and second rolls adjacent to each other, wherein the first and second rolls are configured to roll the coating film material and transfer the coating film material to a coated object to thereby manufacture the coating film product,
- wherein an arithmetic average roughness on a roll surface of the first roll is higher than a value 0.05 times 1 μm as well as smaller than a value 20 times 8 μm,
- wherein an arithmetic average roughness Ra at a central portion on the first roll surface is smaller than an arithmetic average roughness at an end portion, and
- roll rotation directions of the first and second rolls differ from each other.
