Turn handle: feels light spool
Common faucet spools have steel ball spools and ceramic spools. The steel ball valve core has good resistance to pressure, but the disadvantage is that the rubber sealing ring that acts as a seal is easy to wear and will soon age. Compared with the steel ball valve core, 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, Pengguna tidak dapat melihat kili ketika membeli, Tetapi pengguna hanya boleh menilai sama ada kili baik atau buruk mengikut rasa ketika menghidupkan pemegangnya. Secara umum, turning the handle up, turun, kiri, dan betul, if it feels light and has no blockage, it means the spool is better.
Lihatlah penampilan: 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. Selepas ujian, salutan harus bebas dari karat. It is understood that only the faucet passed the neutral salt spray test can be shipped. Semasa membeli, it is best to place the faucet in a place with sufficient light. The surface of the faucet should be bright as a mirror, tanpa sebarang bintik yang teroksida, tanda terbakar, Tiada liang, tidak melepuh, Tiada penyaduran kebocoran, warna seragam; 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. Semakin tinggi kemurnian tembaga, semakin baik kualiti penyaduran, 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. Secara umum, consumers can use the method of estimating weight when purchasing. Tembaga lebih berat dan lebih sukar, 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. Sekiranya laporan ujian menentukan bahawa produk itu layak, it can be purchased.
Test water flow: subject to foaming
Consumers should try to choose a faucet with a aerator when purchasing, dan merasakan aliran air dengan sentuhan tangan. Aliran air lembut dan berbuih (the bubble content of the water flow) kaya, menunjukkan bahawa kualiti aerator lebih baik. The aerator generally consists of six layers, biasanya terdiri daripada penutup mesh logam (sebahagian plastik). Apabila air mengalir melalui penutup mesh, ia dipotong menjadi sebilangan besar lajur air kecil dengan udara di antara, so that the water is not torn apart.
