Heat is transferred through three modes: conduction, convection and radiation or infrared. Radiation is main mode of all the three and other two are secondary and come to the forefront only when matter stars interfering with radiant heat transfer. All substances require transfer heat including air spaces.
Heat transfer rate is changed depending on differences in weight, shape, density, permeability and molecular structure. Heat is conducted and radiated in all the directions by all the objects but gets convected upward mainly. The infrared rays travel at the speed of light as energy and do not have a temperature.
When infrared rays strike on the surface of an object or matter the rays are absorbed and after that heat is produced on the object. The heated object transmits infrared rays from the exposed surface through radiation if the surface is directly exposed to air space. The radiation amount emitted is a function of Emissivity factor of the source’s surface. Emissivity is a rate at which the radiation is given off.
Many materials used in construction have emissivity and absorption rate from 80 to 93%. The surface of aluminium conversely does not have an absorption ability but reflects 95% of infrared rays striking it. Aluminum foil has a low mass to air ratio and very little conduction takes place especially when only 5% of rays are absorbed.
Thermal liners work like a woven laminate to provide complete humidity-controlled environment and sealed off temperature for cargoes that need reheating before unloading. The liner is manufactured by using WPP fabric and has polythene sheeting and an aluminum foil. It is a preferable option for 20 and 40 feet container liner and protects the content inside by reflecting 97% of radiant energy.
The Thermal Liners are mainly used for transporting food and non-food items like beverages, fruit juices, mineral water, milk powder, detergents, cosmetics, fruit juice concentrates, mayonnaise and different types of heat-sensitive chemicals and adhesives.
Besides Rishi FIBC thermal liners we also offer customized liners to meet the exclusive demands of our clients during the transportation of food-grade and non-food-grade items. There are many temperature-sensitive cargoes beside other items that can be transported with the help of thermal liners.
Benefits of Thermal Liners:
- Easy installation
- Excellent moisture barrier
- Prevents contamination by making an oxygen barrier
- Outstanding affordability
- Protects cargo from unfavorable climatic conditions
- Excellent strength and versatility
