Equipment advantageÂ
1. Fine workmanship, high precision, reliable quality, beautiful appearance
2. Accurate dosing for each raw material. Starch mixing tank uses stainless steel, with long service life and low corrosive. The foaming agent reserve tank is made of stainless steel. Foaming system adopts domestic advanced technology - Dynamic and static foaming system, ensuring the finished board is lightweight, good bending strength and saving much cost.
3. The cutting machine uses dual-servo motor, only 1 mm gap between cutting saw, saving cost.
4. Drying system: using heat conduction oil furnace as heat source, the hot oil will be exchanged to hot air by the fin type heat exchanger, then the hot air enters the drying room through the fan, to work together with the heat conduction oil pipe to dry the gypsum board. There are totally 3 drying zones, can perfectly finish the drying curve, avoid over-burning or not dry enough. This technology is environmental, energy saving, high thermal efficiency, process parameters and easy to control.
5. High electrical automation degree, low failure rate, less workers.
6. Forming system: forming belt 14mm thick, can improve the flatness of gypsum board. The wet board cutting machine uses frequency conversion code cutting technology, so can ensure the length tolerance to be mm.
