Turn handle: feels light spool
Common faucet spools have steel ball spools and ceramic spools. Stålkulventilkärnan har gott motstånd mot tryck, but the disadvantage is that the rubber sealing ring that acts as a seal is easy to wear and will soon age. Jämfört med stålkulventilkärnan, 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. The faucet with ceramic valve core is more comfortable and smooth in hand, and it is quick to open and close. Since the spool is inside the faucet, the consumer can’t see the spool when purchasing, but the consumer can simply judge whether the spool is good or bad according to the feel when turning the handle. I stort sett, turning the handle up, ner, vänster, och rätt, if it feels light and has no blockage, it means the spool is better.
Look at the appearance: 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. Efter testet, Beläggningen ska vara fri från rost. It is understood that only the faucet passed the neutral salt spray test can be shipped. Vid köp, it is best to place the faucet in a place with sufficient light. The surface of the faucet should be bright as a mirror, utan några oxiderade fläckar, brända märken, inga porer, ingen blåsande, ingen läckageplätering, uniformfärg; 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. Ju högre mässingens renhet, Ju bättre pläteringskvalitet, 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. I allmänhet, consumers can use the method of estimating weight when purchasing. Mässing är tyngre och svårare, 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. Om testrapporten fastställer att produkten är kvalificerad, it can be purchased.
Test water flow: subject to foaming
Consumers should try to choose a faucet with a aerator when purchasing, och känna vattenflödet med handkörningen. Vattenflödet är mjukt och skummande (the bubble content of the water flow) är rik, indikerar att luftkvaliteten är bättre. The aerator generally consists of six layers, Vanligtvis består av ett metallnätskydd (delvis plast). När vattnet rinner genom nätskyddet, Det skärs i ett stort antal små vattenspelare med luft däremellan, so that the water is not torn apart.
Recognition of the brand: after-sales service is guaranteed
Slutligen, consumers should go to the formal market and supermarkets to buy branded taps. Varumärkesvaror har tillverkarens varumärkesidentitet. Icke-formella produkter eller kvalitetsprodukter har ofta bara några pappersetiketter anslutna, eller till och med inget märke. The manufacturer’s brand logo, quality assurance certificate and after-sales service should also be included in the faucet packaging box. Var noga med att uppmärksamma köpet.
