Aluminum color coating line;

1 This equipment is used to form a layer of porous film on the top of aluminum sheet after the process of degreasing and chemosynthesis so that the primer ,backside and finish paint of colorful coatings can be lacquered on the surface of the film substrate by means of continuous rolling coating, thereafter, the beautiful and elegant colored aluminum coil can come out through the roasting and drying. Functionally, this kind of machine can meet the  color homogeneity and be sure the coating film tolerance within 5μm as well as the coating utilization rate more than 96%.

2, Skim, cleaning all USES high pressure heating spray treatment method,  unoil and Skin membrane pretreatment all use The most advanced aluminum roll single wall of mobile uncoiler with tension ratio automatic control system to send aluminum volume  Stable effectively .then make the aluminum  to skim and Skin membrane pretreatment ,at last In precision coating machine for roller coating homework

3, environmental protection no  chrome roller coating way generate porous membrane layer shape, the weight of the membrane is about 20 to 100 mg/m2.

 

4, Precision coating machine use  reverse type roller coating method, can make the paint on the surface of the aluminum volume precision and uniform. The roller coating wheels adopt high strength steel tube, After grinding and hard chromium plating, then Precision grinding the surface again ,the Surface accuracy is within 0.003mm, Straight tube degrees  is within 0.005mm

5,Baking furnace hot air circulation system by using natural gas heating, with PID automatic thermostat, not only can program calculation precision control of temperature difference but also can effectively to save energy.

6, The design has the edge device and totally satisfied production of aluminum the edge of volume requirements.

7,The equipment can be used for single roller coating polyester ,acrylic acid, acrylic coating to bake the coating 8,Adopting  hydraulic power automatic tracking device can ensure the edge, aluminum collected volume of edge when all side not beyond ±2mm .

9,Adopting  hydraulic power automatic tracking device can ensure the edge, aluminum collected volume of edge when all side not beyond ±2mm .
