Turn handle: feels light spool
Common faucet spools have steel ball spools and ceramic spools. Le noyau de soupape à billes en acier a une bonne résistance à la pression, but the disadvantage is that the rubber sealing ring that acts as a seal is easy to wear and will soon age. Par rapport au noyau de la soupape à billes en acier, the ceramic valve core is more resistant to heat and wear, and the ceramic valve core itself has a good sealing performance, so that a high degree of opening resistance can be achieved, and the nozzle is not dripped due to the wear of the valve core. Le robinet avec noyau de valve en céramique est plus confortable et lisse à la main, Et il est rapide à ouvrir et fermer. Since the spool is inside the faucet, Le consommateur ne peut pas voir la bobine lors de l'achat, Mais le consommateur peut simplement juger si la bobine est bonne ou mauvaise selon la sensation lors de la tournure de la poignée. En général, turning the handle up, vers le bas, gauche, et à droite, if it feels light and has no blockage, it means the spool is better.
Regarder l'apparence: the coating should be bright as a mirror
After the faucet is ground and polished, the surface should be plated with nickel or chrome. The water faucet is oxidized. After the nickel or chromium plating, the faucet pass the Neutral salt spray. Après le test, Le revêtement doit être exempt de rouille. It is understood that only the faucet passed the neutral salt spray test can be shipped. Lors de l'achat, it is best to place the faucet in a place with sufficient light. The surface of the faucet should be bright as a mirror, sans taches oxydées, marques brûlées, pas de pores, Pas de cloques, Pas de fuite, couleur uniforme; The hand touches no burrs and sand grains; after pressing the faucet with a finger, the fingerprint spreads quickly and is not easy to adhere to dirt.
To be tested: quality is more guaranteed
The main body of the faucet is generally brass. The quality of the products made of brass is guaranteed to be the best. The higher the purity of the brass, the better the plating quality, and the harder the surface plating layer is. In order to reduce costs, some manufacturers use zinc alloy instead of brass. Although the country allows the use of zinc alloy materials instead of brass, the zinc alloy plating quality is poor and the corrosion resistance is not strong. En général, consumers can use the method of estimating weight when purchasing. Brass is heavier and harder, and zinc alloy is lighter and softer. Experts caution that the quality of the faucet should not be judged by weight alone, because some manufacturers can make the faucet heavier by increasing the wall thickness of the faucet or adding other metal materials. Consumers should ask the salesperson for a test report for the product. Si le rapport de test détermine que le produit est qualifié, it can be purchased.
Test water flow: subject to foaming
Consumers should try to choose a faucet with a aerator when purchasing, et sentir le flux d'eau avec la touche à la main. Le débit d'eau est doux et moussant (the bubble content of the water flow) est riche, indiquant que la qualité de l'aérateur est meilleure. The aerator generally consists of six layers, Composé généralement d'un couvercle en maille métallique (partiellement en plastique). Lorsque l'eau traverse le couvercle en maille, il est coupé en un grand nombre de petites colonnes d'eau avec de l'air entre les deux, so that the water is not torn apart.
