Production Machine of Fiberglass Chopped Strand Mat -Drying Oven

Production Machine of Fiberglass Chopped Strand Mat -Drying Oven
     The drying-oven is composed by a tunnel thermally isolated and furnished with a conveyor belt.

     The drying-section is heated by the direct-gas-fired system.

     The dryer is divided in zones. Each zone has a circulating fan and separate temperature controls.

1. Conveyor Belt

      The belt of the conveyor is a special stainless steel wire mesh, of the upper side, the mesh is supported by a series of rollers equipped with ball-bearings (outside of the oven).

      Cleaning brushes and cleaning burners are mounted on the conveyor belt.

      A belt guiding and tension system is provided. 

2. Ventilation

      Over and under the upper belt section are mounted special air-distributing cases. The upper ones are blowing and the under ones are sucking. 

      They are providing the rational distribution and the ventilation of the air all over the surface of the mat. under the sucking cases are mounted air-filters of mat or of veils.

      The motion of the air in each sector is provided by heavy duty ventilators with  special shovels.

      The construction of the ventilators and the air popes for the blowing and  sucking and the cases is realized in matter to make easily the cleaning operations.

3. Exhausted air

      In the sections, exhausters will provide for the exchange of the circulating air.

4. Air-Heating

      Each section is furnished with his own gas burner. After passing the material to dry, the hot air is sucked by the lower cases and therefore returns in cycle.

      The fresh air is sucked by holes with filters, opportuned placed on the sucking pipe.

5. Control Unit of The Burning and The Temperature

       Each burner is furnished with a set of controls for the temperature regulation. 

       Each set is composed by :

Temperature regulator

The thermo states of max. and min.

The timer for the burning cycle

The control U.V, photo cells

The servo control  for the flame modulation  

      For the circulating, the exhaust and the combustion air are foreseen control units of the pressure.

      All these units will be placed into a control-panel.

6. Thermal insulation cleaning and accessibility

      The drying tunnel is composed by a strong frame of iron U-profiles, covered with insulating panels, the hole structure is dis-assemblable.

      By planning the structure we have considered the thermal expansion and provided for the necessary. the insulating panels are manufactured with special iron sheets. 

      They are filled with glass wool.

      Along the sides of the oven, at a suitable distance, are mounted inspection doors.

      The distribution cases are furnished with openings to make easy the cleaning and maintenance.

Binder Applicators System For Fiberglass Chopped Strand Mat

Powder Binder

The glass fibers are transferred from the conveyor belt of the forming section to another conveyor belt for the binder application. The forming belt will remain clean and dry everytime. Binding with powder is composed by 2(two) powder-binder-applicators, and a series of sprays of demineralized (distilled) water.

Both sides of the mat, the upper and the lower-one, are lightly sprayed with distilled water, that operation is necessary or a better adhesion of the binder. The special powder-applicators warrant an optimal distributing .

Between the two applicators a vibrator is applied providing that the powder is also passing to the lower side of the mat.

Binding with Emulsion

The curtain system used warrants a perfect distribution of the binder. The excess of binder will be recovered by a special sucking system.

This system pulls the air through the fiberglass chopped strand mat and a part of the binder will be taken off. By that mater the binder will be distributed uniformly and the excess of binder eliminated. 

Obviously the binder will be re-employed after special filtering which separates the air and the dirt.

The binder is stored in containers in the mixing room and conveyed at low pressure by a pipeline to a small tank near the mat-plant.

A special device maintain the level of the tank constant. Also the recovered binder will be conveyed to the tank. A pumping system conveys the binder from that tank to the curtain distribution system.

Description of the Manufacture of Fiberglass Chopped Strand Mat

 Fiberglass Chopped Strand Mat is an unwoven fabric consisting of strands chopped into 25-50 mm lengths, deposited at random in a horizontal plane, and held together by means of a suitable adhesive. Adhesives are of two powdered polyesters.  While the physical properties of composites are governed by the composition of the fiber size, the choice and quantity of adhesive is mainly responsible for the handling and moulding properties or the mat.

    

     The starting materials for chopped strand mats are glass fiber manufacturers use cakes entirely, although some often use roving, in part to save floor space.

    Very important for the quality of the mat is the good sizing of the fibers to give a good chopping characteristic and low static-electrical load.

    The plant is composed of the following sections :

   -. Fiber Creel

   -. Feeding and Cutting Service

   -. Forming Section

   -. Binder Applicators system

   -. Drying Oven

   -. Cooling and compaction

   -. Trimming and Winding

Creel Frame

     The spincake bobbins are placed in suitable number on the creel frames. Frames these creels the fiber cake are un-winded, the cake creel area should be in an air conditioning room with a reality humidity of 82-90 % 

Feeding an Cutting Device

     Through the feeding rolls the strand are drawn from the cakes. 

     To each of the cutters will be conveyed a partial of the total number of bobbins.

Forming Section

     The mat is formed by cutting a great number of strands through cutting devices which are disposed at equal distance on the top of the forming chamber. Each device is furnished with a motor with variable speed. the cutting devices are controlled independently, that allows an uniform distribution of the fibers. Inside the forming chamber there are strands dispersers with air support.

     A section box below the wire mesh belt sucks the strand onto the belt. 

     The exhaust air is cleaned by filters.

FIBREGLASS (FRP/GRP) PIPE SYSTEMS ADVANTAGE

Nowadays, although corrosion resistance continues to be an important benefit, the other unique advantages of FRP have won the material an ever increasing acceptance in a constantly expanding range of applications where corrosion resistance is not necessarily a primary consideration. 

This is especially true in applications requiring very large diameter pipe. One example of this is the 30 x 10m long 1,200mm diameter casings we provided for bridge building over rivers and estuaries where the pipe can be provided in the desired lengths as a former to pouring concrete pilings.

FRP pipe has an exceptional strength to weight ratio, because pound for pound fiberglass is stronger than steel. As a result the pipes have a high tensile strength as well as good shock and impact resistance. They also have excellent flow characteristics as a smooth glass-like finish reduces material build-up and improves fluid transmission. 

Fiberglass Pipe is available in standard diameters from 50mm to 2m, with larger diameters available on request. These are also supplied with a range of fittings, such as flanges, elbow, tees to suit the installation.
