As the core component of the faucet – the valve core, it largely determines the service life, quality and quality of the faucet. Therefore, to improve the quality of the faucet, it is necessary to start from the valve core, and the material of the valve core determines the quality of the valve core. According to the different materials, the cartridge can be divided into rubber cartridge (slow-opening cartridge), ceramic cartridge (fast-opening cartridge), ball cartridge, stainless steel cartridge and so on.
- Rubber cartridge
The faucets with rubber valve cores are mostly screw-type iron cast faucets, but they have basically been eliminated. This material of the faucet spool has a short service life and is prone to leakage.
- Ball spool
According to the information, the ball spool was first used in 1960, while most ball spool faucet handles can only be installed in the middle position. The advantage of this spool is that the stainless steel ball used has corrosion resistance; in addition, from the point of view of cost savings It is reported that the ball can also be made of cheap materials such as plastic. The disadvantages of ball faucets are the number of fittings installed and the frictional resistance, which can cause the faucet seal to fail and lead to leakage.
- Ceramic valve core
Ceramic valve core is currently very popular in the market as a new material for technological innovation. Its advantages are less pollution of water, low price, long service life, good sealing performance, more economical and environmental protection. In addition, ceramic has a strong physical stability, in the use of the process can withstand wind, sun, rain, high temperature, low temperature, wear-resistant; and its surface by a variety of erosion is not easy to corrode and deformation. These properties of ceramic is an important factor in determining the life of the faucet. Therefore, the normal service life of ceramic spool is generally more than 10 years. The disadvantage of ceramic spool is that it is fragile and easy to break. Ceramic is also prone to immersion in water. The intrusion of the cartridge and the high water quality requirements during use also limit its use.
- Stainless Steel Spool
Stainless steel is another new material following the technological innovation of the faucet valve core. It focuses on long service life, corrosion resistance, easy to wash off. Compared with ceramic valve core, its biggest feature is not high water quality requirements, not easy to be eroded by the impurities in the water, affecting the service life. Therefore, stainless steel faucet valve core is particularly suitable for use in areas with poor water quality. In addition, it is easy to dismantle and wash, and consumers can complete simple maintenance and installation work themselves. However, there are shortcomings, that is, it is more expensive.
Long time, no rust, can not fully reflect the good or bad faucet. In recent years, the kitchen bathroom metal use exceeds the standard, resulting in human metal poisoning incidents, which has also caused attention to the safety of the faucet. For the faucet, in addition to paying attention to its durability, it is more important to pay attention to its impact on human health. The impact of the faucet on human health comes from the material of the valve core on the one hand, and the overall material of the faucet on the other.
