440 is a kind of Excellent choppability and wet-out SMC roving. Suitable for water tanks.
440 is a general purpose SMC roving coated with a silane-based sizing compatible with unsaturated polyester and vinyl ester resins.
440 is Excellent choppability and wet-out compared with other same series products.
440 is suited for the production of low and ultra-low shrinkage sheets. These sheets are essential in the manufacturing of a wide range of components, predominantly used in the automotive industry. They find extensive application in the production of door skins, which are a critical component of vehicle doors, contributing to their structural integrity and aesthetic appeal. Additionally, these sheets are vital in the construction of water tanks, where they provide durability and resistance to the effects of water exposure. Their utility extends to the electrical components industry as well, where they are used in the creation of various parts that require high-quality, reliable materials.
In summary, 440 is a versatile and highly compatible SMC roving that is ideal for producing low and ultra-low shrinkage sheets.
Good anti-static property: This material boasts a superior anti-static attribute, which is highly beneficial in environments where static electricity could be problematic.
Excellent choppability wet-out: Its impressive wet-out choppability means that it can be easily cut, shaped, and manipulated when submerged in a liquid medium, such as during the molding process, ensuring seamless integration and reducing the likelihood of air pockets or voids.
Excellent strength of parts: The parts produced exhibit remarkable strength, ensuring durability and resilience in applications that may subject them to mechanical stress or environmental factors.
Water tank as an important equipment for storing water resources, its characteristics and functions mainly revolve around the following aspects:
The inner wall and bottom of the tank are usually specially treated or sealed to prevent water leakage. This is especially important in situations where outdoor use or potential water leaks could have an impact on the environment.
For cold water or storage water that needs to maintain a certain temperature, such as hot water tanks, there may be a thermal insulation layer or insulation material inside to reduce heat loss or maintain a suitable storage temperature.
The water tank should be able to withstand the pressure of its own full load without breaking. Especially in the high pressure system, the pressure performance of the water tank is higher.
The design of the water tank should consider the influence of environmental factors such as wind, snow and earthquake to ensure that it can maintain its morphological stability under various external conditions.
Modern water tanks are usually designed to be more modular or standardized, easy to transport to the site for installation, and the internal space is large, easy to clean and maintain.
High-quality water tanks usually have good corrosion resistance and long service life, reducing the need for replacement or maintenance.
According to the different application sites (such as urban, rural, industrial areas), the tank may need to adapt to extreme temperatures, high salinity waters, polluted environment and other specific conditions.
