The functions for our chopped spraying machine are: Two-component automatic external mixing and spraying The machine can chop the glassfiber during the spraying process There is a valve at the resin side of the spraying gun, and also the gun body and the pipe are separated, which makes the disassembly and maintenance quick. This kind of spraying gun adopts airless spraying, and so it is helpful for pollution reduction and material saving but not damage the quality.
1:Resin spray 3.5-5Kg/min
2:Chopped glass fiber 1.5Kg/min
3:Pressure ratio 18:1
4:Adjustable range of curing agent ratio 0.8-3%
5:Working air pressure 0.3-0.6Mpa
6:Air consumption 50-500L/min
There are Arm Type Chopping Spray Machine (Length of pipeline 8m) and Light Type Chopping Spray Machine (Length of pipeline 8m ---15m)
Chopping Spray Equipment List:
One equipment trolley (arm type or light type), one pneumatic resin pump, one curing (firming) agent pump, one firming agent charging basket, one set of air distributing device, high pressure resin tube, firming agent tube, compressed air tube (two), each 8-15m (different trolleys), one set of chopping spray gun and one set of wearing parts.
The new generation chopping spray machine inherits simplify of the traditional ones and designed to be more human.
Spray structure with external mixing is adopted for resin spray, and it can effectively avoid internal gun solidification and easy to control the spray of firming agent at any time. So the problem can be solved timely (in case of any), and can guarantee the quality of products. Adopt up-and-down double nozzle structure to make firming agent atomization smaller and more uniform, eliminate non-uniformity or un-synchronization of products. The nozzle of spray gun is designed with auxiliary air protection structure, which reduces splash of raw materials and pollution to the environment. A totally new design for the spray gun structure is that the gun is composed by two separate blocks: pipe block and main gun block. A hand switch is equipped for the resin pipe of the pipe block, which makes the resin pipe can be repaired at any time and no need of pressure relief. The new spraying gun adopts particular wear-resistant hard alloy for the resin needle valve and nozzle, and so it is perfectly suitable for the processes that a large portion of filler should be added into the resin such as making sanitary appliances. The new type spray gun can be a nice gel coat spray gun as long as a nozzle is changed.
Strongpoint in application of chopping spray machine:
The components consisted by this equipment are of high integration and without lap seam. Uncomplicated moulding process with high productivity No limit for product's size and shape basically Save materials, material prescription can maintain a certain accuracy which is helpful to enhance the product quality and stability.
Application To make liner and end enclosure by chopped spraying for fiber glass tank To make the fiberglass products of uncomplicated shapes by spraying To make sanitary ware;
To make auto parts and compartments
To make arts and crafts
3. Automatic spray gun used for vertical winding.
