Carefully observe the reflection on the surface of high-grade sanitary ware products from the side, and the surface with no or little trachoma and pitting is better. Products with high brightness index use high-quality glaze materials and very good glazing process, good reflection of light, so that the visual effect is good. You can gently rub your hand on the surface to feel very smooth and delicate. You can also touch the back, and feel the subtle friction of “rustling”. The ceramic surface can be tapped by hand, and the sound of the generally good ceramic material is relatively crisp. Mainly to investigate the water absorption rate, the lower the water absorption rate, the better. Ceramic products have a certain adsorption and penetration capacity for water, and if water is sucked into the ceramic, it will produce a certain expansion, which is easy to crack the enamel on the surface of the ceramic due to expansion. Especially for the toilet, if the water absorption rate is high, it is easy to inhale the dirt and odor in the water into the ceramic, and the odor that can not be removed will be produced for a long time.
Good sanitary ware should not only look beautiful, but also conform to the body function, comfortable to use. The manufacturer’s mold, equipment and design capabilities are decisive factors. High-level manufacturers generally use imported molds. Traditional sanitary ware copper water parts, float irrigation has been eliminated, the current good sanitary ware water parts are imported pvc materials, vacuum irrigation technology, corrosion and rust performance and leakage performance are greatly improved. The water parts of famous brand sanitary ware are supplied by professional manufacturers. The brand of glaze, the thickness of glaze layer, and the firing process of sanitary ware directly determine the effect of sanitary ware glaze. The imported glaze, the surface of the sanitary ware with thick glaze layer is smooth and delicate, the texture is full, and the crystal clear looks very comfortable. Moreover, this kind of sanitary ware has strong self-cleaning ability and low water permeability. The downwater pipe and the inner wall of the water tank of the middle and high grade sanitary ware are also glazed, which is very important to prevent the toilet from hanging dirty, and whether the downwater pipe is glazed is also an important sign to judge the grade of sanitary ware.
