Roll coater and spraying machine coating equipment are the main two machines, which are in the form of spray and roll-form naming categories.
Wherein the roll coater is the traditional paint mist in liquid form, by the rotation of the pressing roller, so that the paint adhered on the coated plate reached; paint sprayer is a liquid water mist sprayed onto coated plate reached installed. Here the contrast roll coater and spraying machines to be explained.
First, roll coater cost advantage compared to spraying machine:
1, low cost: the purchase of machinery and equipment investment is a lot of money, so the cost of machinery and equipment is more important considerations, roll machines typically priced at a few the million or so, while a spraying machine to get at least a hundred thousand dollars to purchase.
2, efficiency: roll coater continuous operation, simple operation, high fault tolerance, multiple long usually sprayer when each job.
3, save paint: the paint roller coater cyclic use, with paint recovery tank, substantially all the paint without waste.
Second, compared to roller coater, a spray coater practical advantages:
1. Applicability: automated sprayer spraying forms, due to the natural randomness spraying, not only suitable for coating flat plate member, the plate shaped member for her more non- none other.
2, coating effect: high coating effect than the effect roller, and a more uniform spray mechanized, and also high tunability.
3. Independence: usually a spraying machine can be completed painting - primer coat even the front and back, and roll coating machine often need to complete the job in order to cooperate with other painting equipment.
The above points are the basic difference between a roller coater and spraying machine pros and cons of the key points, which is better not conclusive, except to say which is more in line with the actual situation of the customer, make the plane of the panel should be selected roll coater, such as UV roll coater ; do sprayer doors should be selected, such as painting machine doors.
