1
|
pretreatment
|
Wall material
|
+PVC
Stainless steel+PVC anticorrossive system |
Stainless steel
|
Stainless steel+PVC anticorrossive system has stronger ani ecrossion with longer life.
|
|
|
|
|
Waterfall equipment
|
Stable pressure water pump + duck mouth faucet
|
Basin
|
The water with chemical fall down more stably and smoothly and make profile cleaning better.
|
|
|
|
|
Water Pump
|
Horizontal fluoroplastics pump or Alloy pump
|
Alloy pump
|
fluoroplastics pump: outside is metal,inside is fluoroplastics , be suitable for -85～150℃ corrosive material, it is the most
advanced anti-corrosive in the world .It has longer life than alloy pump. |

|
Powder coating booth
|
The third generation V shaped booth + PE double side recycling belt(automatic cleaning self)
|
The first generation V shaped booth +polythene film recycling belt
Or the second generation U shaped Booth+ PE recycling belt |
Our third generation booth : no powder overflow,
Powder recycling can be done just by a vacuum pump. The energy consumption is better than the first generation and second generation one. Morever ,it is more easily to clean and shorten the cleaning time. Our PE belt can be recycling use and save cost from long term. |
|
|
|
|
The first recycling system
|
Big cyclone
|
Big cyclone
|
Our recycling rate is more than 97%. Can save 1-2kg powder per ton profile basis on the common used powder |
|

|
Reciprocator
|
The running rail use real lift rail.
The wheel use polyurethane. Use digital frequency conversion to adjust speed. Use stroke limit switch. PLC + touch screen full automatic control |
|
The wheel runs in the rail stably and smoothly, with low noise,extend the use life.
The reciprocator speed fully match the convey chain, running smoothly to assure the the coating thickness even. The stroke control is done by stroke limit switch. Besides, also designing a mechanical stroke limit control to double assure better control even if there is wrong with the switch control. |

Vertical curing oven
|
Heat preservation
|
Oven wall:
Inner wall plate δ1.2mm galvanized plate + 50+80mm rock wool + 40mm heat insulation wool + outer wall δ1.0mm coating plate |
Oven wall:
Inner wall plate δ1.2mm galvanized plate + 120mm rock wool + 40mm heat insulation wool + outer wall δ1.0mm coating plate |
Heat insulation is better. Out wall temperature is low . The temperature difference between oven outside and indoor temperature is
less than 15℃. |
|
|
|
|
Heating method
|
Direct heating
|
Indirect heating
|
Gas direct heating can save more 10% -20% energy than indirect heating system. And no smoke produce.Don’t need buy smoking removing equipment. |
|
|
|
|
Temperature measuring
|
In the oven ,there are 6 different area temperature measuring and temperature sensor which can automatically measure temperature.
|
6 different area temperature measuring ,no temperature curve graph .

Convey chain
|
Brand
|
Chengde Guangda chain
|
Produced by themselves
|
The chain is produced and designed by famous company in China. Running is stable and smooth.life is longer and so on. But price
will be more expensive. |
