1, acrylic bathtub-has a large market share. The surface of acrylic material is polymethyl methacrylate, and the back is resin gypsum and glass fiber.
Advantages: easy molding; Good thermal insulation performance; Good gloss; Light weight and convenient installation; There are various shapes and colors. Because of the above characteristics, the price of acrylic bathtub is lower.
Disadvantages: Compared with the surfaces of ceramics and enamels, the disadvantages of acrylic materials are easy to hang dirty, loud noise during water injection, poor high temperature resistance, no wear resistance and easy aging and discoloration of the surface, but the quality of imported acrylic cylinders is relatively better.
2. Cast iron bathtub-made of cast iron and coated with enamel.
Advantages: long service life, high grade, easy cleaning, thick wall and good thermal insulation performance. Moreover, the cast iron cylinder has good gloss and the service life is the longest among the three cylinders. The acid and alkali resistance and wear resistance of cast iron bathtub are better than similar products.
Disadvantages: It is quite heavy and difficult to carry and install. Because of many factors, the price of cast iron bathtub is much more expensive than acrylic and steel bathtub, and the price is the most expensive.
3. Steel plate bathtub-The steel plate cylinder is made of a whole bathtub-specific steel plate with a thickness of about 2 mm, which is stamped and molded with enamel surface.
Advantages: it has the characteristics of wear resistance, heat resistance and pressure resistance. Its weight is between the cast iron cylinder and the acrylic cylinder, and its thermal insulation effect is lower than that of the cast iron cylinder, but it has long service life and high overall cost performance. Not easy to hang dirty, clean, not easy to fade, lasting luster, easy to shape and cheap.
Disadvantages: Because the steel plate is thin, the firmness is not enough, the noise is loud, the surface is easy to take off porcelain, and the thermal insulation performance is not good, so some of them add thermal insulation layer.
4. Wooden bathtub-made of nanmu, cypress, oak, Chinese fir and pine. Nanmu bath bucket has the best comprehensive performance, but it is rarely seen in the market. Pine and Chinese fir bath barrels are easy to get wet, black and moldy, and their comprehensive performance is poor.
Advantages: thermal insulation, environmental protection, small floor space, easy cleaning, long service life and convenient installation.
Disadvantages: under the condition of long-term drying, it is easy to crack, so if it is not used for a long time, put some water in the bucket.
