1. Look at tempered glass
① Check whether the glass is transparent, whether there are defects such as dots and bubbles.
Brief analysis: The impurity of the glass material or the defects of the craft will cause the glass to have defects such as dots and bubbles, and reduce the hardness and strength of the glass.
②Check if there is 3c mark certification on the original glass.
Brief analysis: 3c certification is the abbreviation of China Compulsory Product Certification, shower room products without this mark cannot be sold.
③Look at the model of fully tempered glass fragments
Brief analysis: According to the national standard, the safety amount of toughened glass per 50*50mm area must reach more than 40 pieces.
2. Look at the acrylic material
Acrylic panels, it is understood that some glass filaments used in composite acrylic panels contain formaldehyde, which is one of the sources of toilet pollution. The way to distinguish the acrylic material is to look inside the shower room. If the back side of the acrylic board is different from the front side and is rougher, it is a composite acrylic board. For example, some acrylic sheets will change color if they are used for a long time, and some will have small cracks. This is the main reason why some brands of shower rooms are expensive and some are cheap.
3. Look at aluminum
①Look at the hardness of aluminum
Brief analysis: shower room aluminum often needs to support the weight of tens of kilograms or even hundreds of kilograms of glass. If the hardness and thickness are not good, the shower life will be very short. The hardness and thickness of all aluminum materials are important assessment indicators. The thickness of the qualified shower room aluminum material is above 1.2mm, and the glass aluminum material for hanging on the rail must be above 1.5mm. The hardness of aluminum can be tested by pressing the aluminum frame by hand, and it is difficult for an adult to deform the aluminum with a hardness of 13 degrees or more.
②Check whether the surface of the aluminum material is smooth, whether there is color difference and trachoma, and the profile finish.
Brief analysis: When the second-hand waste aluminum material is processed, the smoothness of the surface is not enough, there will be obvious chromatic aberration and trachoma, and the finish of the special section is dark.
4. Look at the pulley
①Look at the material of the pulley and the sealing of the wheel seat
Brief analysis: The wheel seat of the pulley should be made of compression-resistant and heavy-duty materials, such as 304 stainless steel and high-end synthetic materials. The seal of the wheel seat is good, water vapor is not easy to enter the wheel, and the smoothness of the wheel is guaranteed.
②Look at the fit of the pulley and aluminum track
Brief analysis: the pulley and the track should be closely matched, with a small gap, and not easy to fall off when impacted by external forces to avoid safety accident
