Double Mouthed Bag (Sterile Filling Aluminum Plated Composite)

Industry knowledge

How can manufacturers of transparent bag-in-box with duckbill valve made of nylon composite ensure that nylon composite materials have sufficient strength and wear resistance while maintaining high transparency?

Material selection:
Select high-quality nylon resin as the base material to ensure its physical properties, such as strength, wear resistance and high temperature resistance.
Mix appropriate amount of transparent additives, such as transmittance enhancer, refractive index matching agent, etc. in nylon resin to improve the transparency of the composite material.
Formula design:
Finely adjust the formula ratio in nylon composite materials, including the amount of nylon resin, transparent additives, reinforcing materials (such as glass fiber, carbon fiber) and other additives, to achieve the best balance of transparency, strength and wear resistance.
Select appropriate additives, such as silica, graphite, etc., to enhance the hardness and wear resistance of the material while maintaining transparency.
Production process:
Adopt advanced production processes and equipment, such as high-temperature melt mixing, precision extrusion, compression molding, etc., to ensure that nylon composite materials can be evenly mixed and fully cured during the manufacturing process, so as to obtain excellent performance.
Strictly control parameters such as temperature, pressure, speed, etc. in the production process to avoid adverse effects on material properties.
Quality control:
Strict quality inspection of raw materials to ensure that the quality and performance of raw materials meet the manufacturing requirements.
Quality control of key nodes in the production process, such as mixing uniformity and curing degree, ensures that the performance of nylon composite materials is stable and reliable.
Strict quality inspection of finished products, including testing of indicators such as transparency, strength, and wear resistance, ensures that the products meet the design requirements.

How does the supplier of transparent bag-in-box with duckbill valve made of nylon composite materials design the sealing mechanism of duckbill valve?

Material selection:
The materials used to make duckbill valves, such as chloroprene rubber, nitrile rubber, fluororubber, etc., need to have good elasticity and corrosion resistance to meet the sealing requirements under different working conditions.
As the base material of bag-in-box, nylon composite materials also provide good support and protection for duckbill valves due to their high strength, wear resistance, and corrosion resistance.
Structural design:
The duckbill valve adopts the design principle of ""forward entry, reverse check"", ensuring that water can flow smoothly when working in the forward direction, and effectively preventing backflow when working in the reverse direction.
The outlet of the duckbill valve closes with its own elasticity to form a seal when there is no internal pressure; as the internal pressure increases, the outlet gradually opens to ensure smooth discharge of the fluid.
Sealing mechanism:
The sealing mechanism of the duckbill valve mainly depends on its unique shape and material properties. In the closed state, the duckbill part fits tightly to form a reliable sealing surface.
The connection between the duckbill valve and the nylon composite bag needs to be tight and leak-free. Special sealants, hot fusion or other sealing technologies can be used to ensure the sealing of the connection.
Installation and debugging:
When installing the duckbill valve, it is necessary to ensure that the connection between it and the nylon composite bag is correct to avoid leakage caused by improper installation.
During the debugging process, the sealing performance of the duckbill valve can be tested by simulating pressure changes under different working conditions to ensure that it can work reliably in actual use.
Maintenance and care:
In order to extend the service life of the duckbill valve and maintain its sealing performance, regular maintenance and care are required. This includes cleaning, checking whether the sealing surface is intact, and replacing severely worn parts.
Note:
When designing, installing and using duckbill valves, it is necessary to follow relevant safety regulations and operating guidelines to avoid safety accidents caused by improper operation.
