1. Construction of composite film curing chamber

1. Before building a composite membrane curing room, you must determine the size and practical area of the curing room according to your own capabilities, which is generally about 1.5 meters × 2 meters.

2. Determine the location of the curing room. The location is usually to use a corner of the composite workshop or bag making workshop and then build a corner and add a door. This saves construction, space and is convenient.

3. The height of the curing chamber is generally about 2-2.5 meters, and it is built into a tower. There is an air outlet with a diameter of 5-250px at the top, which can directly lead to the outdoors. Function: Exhaust the odor of the curing chamber.

4. Leave an air inlet in the curing room and install a small blower for regular blowing. The wind direction should be towards the heat dissipation device 1. Function: Keep the space temperature of the curing chamber consistent and eliminate the smell of items in the curing chamber during curing.

5. Installation of cured indoor shelves: Choose a wall, about 50 cm away from the wall, and erect steel pipe columns from the ground (the diameter of the column is 1.5-2 inches). When it is about 50 cm above the ground, you can use a tee to connect it. Frame shape, one end is inserted into the wall to form a horizontal bar, which can be continuously raised to two to three floors. The columns can be erected in several rows according to the size of the place. The composite membranes are placed on the shelves with steel pipes and discharged in sequence. This installation bracket saves space and materials. Another installation method can use the middle space column of the curing chamber to make several layers of brackets to place the composite rollers. The spare parts for the curing chamber are just a few lengths of steel pipe for the film threading rollers. Function: Place the composite film on the holder, and the effect will be good during the curing period.

6. Indoor thermal insulation structure: Use a 5-250px thick thermal insulation layer on the surrounding walls. Generally, materials with good thermal insulation properties such as perlite or bubble film boards are used for processing. The function: increases the insulation time, saves electricity, and reduces costs.

7. Heating control: The temperature requirement of the curing chamber is generally between 45℃-60℃, equipped with electric heater and heat dissipation device. Choose a convenient place to install indoors, and install it outdoors with automatic temperature control meter. Function: After the temperature is fixed, no special person is needed to control it, saving labor. 2. Use of curing chamber

2. When using the curing chamber, all parts of the curing chamber must be strictly inspected, especially whether the power system is in good condition and can be used without any faults.

1. Turn on the power to heat, and then adjust the temperature controller. The temperature of the curing chamber should be between 45°C and 60°C, reaching the above temperature in a short time.

2. When setting the temperature control, the material and requirements of the packaging bag can be used. The aging period of ordinary composite bags is generally required to be 50°C and more than 48 hours. Retort bags, aluminum foil, aluminum-coated films, and composite bags with three or more layers generally require a temperature of 60°C and more than 70 hours before they can be made.

3. When placing the composite film into the curing chamber, the name, quantity, specification, entry time into the curing chamber, and exit time from the curing chamber should be noted. This should not be confusing, the quality requirements of the aging period.

4. During bag making, if the curing effect is found to be unsatisfactory, the temperature of the curing chamber can be adjusted or the curing period can be increased. The amount of glue applied during compounding can also be adjusted to meet the required standards.
