Production and installation of air duct in cosmetic sterile workshop
How the non-metal ventilation duct of cosmetic sterile workshop is heated and formed:
1. Molding mold
Round air duct and accessories should be prepared before thermoforming. The material of the tire should be made of 1mm thick galvanized steel plate. The small size round tire should be made of wood. The thickness of the tire can be larger than the required size. There should be reinforcement measures at both ends, the tire tool should be accurate in size, the arc transition should be uniform, and the outer surface should be smooth.
2. Circular air duct forming in cosmetic sterile pharmaceutical cleanroom
When heating and forming a round straight tube, first keep the temperature of the electric heating box at 130~140℃, and after the temperature in the box is uniform and stable, put the plate into the box for heating. The heating time is related to the thickness of the plate. The heating duration of different plate thicknesses is shown in the table below.
Heating time of rigid PVC plastic sheet
Sheet Thickness(mm)
2~3
4~5
6~8
9~11
12~15
Heating time(min)
3~5
6~8
9~11
12~14
15~20
When the board is heated to a soft state according to the heating time in the oven, pull the board out of the oven and place it on the working platform where the canvas is placed, wrap the board tightly with the canvas and roll slowly to make the air duct form , after it is completely cooled and shaped, the plastic tube can be taken out; if the processing batch is large, a simple molding machine can also be used for molding.
3. Rectangular air duct forming in cosmetic sterile workshop
The four corners of the rectangular straight tube can be formed by welding or heating. When heating and folding is used, the distance between the longitudinal welding seam and the folding should be greater than 80mm. The folding of the air duct can be carried out with two tubular electric heaters and an ordinary manual edger. The tubular electric heater is heated by energizing the electric heating wire installed in the steel pipe; Insulate with a porcelain tube, the power of the electric heating wire should be able to ensure that the surface of the steel tube is heated to a temperature of 150~170 °C; when folding, place the drawn line plate between two tubular electric heaters to locally heat the folding line. , the heating width is about 5 times the thickness of the plastic board; after the heating part becomes soft, quickly pull out the plastic board and place it on the manual edger, fold the board into a 90° angle, and take it out after the heating part is cooled. Zhongjing Global Purification can provide consulting, planning, design, construction, installation and transformation of sterile rooms and sterile workshops and other supporting services.
4. Forming of pipe fittings in cosmetic sterile pharmaceutical cleanroom
Rectangular and circular reducers, hot forming, can be unrolled according to the metal air duct, and leave a shrinkage margin after heating. The rectangular reducer can be heated and folded according to the method of the rectangular air duct; the round reducer and the Tianyuan place should be placed in the electric heating box for heating, and then formed by the tire mold. The tire mold can be made of thin steel plate or wood. Generally, it can be made according to 1/2 of the whole. When the section is large, it can also be made according to 1/4 of the whole. When making a circular elbow, it should be noted that the longitudinal welds of each pipe section should be staggered from each other, and should not be located on the same side of the elbow. You can also use the round straight pipe that has been processed, and use the expansion template of the pipe section to draw the line for cutting. Then use several pipe sections to weld into circular elbows.
When making a rectangular elbow, the two side panels of the elbow can be cut according to the pattern, and the back plate and the inner plate should be cut with the shrinkage margin after heating, and then use the same arc of the circular straight The tube is used as a tire mold for thermoforming. The circular tee can be closely attached to the processed round head or round straight pipe with the template, and the jig sawing can be drawn along the template, which can be welded and formed. The production method of the rectangular tee is similar to that of the rectangular elbow.
