What are the characteristics of the bathtub?

There are many kinds of bathtubs. Cast iron: advantages: smooth and flat, warm color, anti-fouling, easy cleaning and long life; Disadvantages: the price is the highest, the hardness and heat preservation are not as good as acrylic cylinders, and the color and shape are limited by technology, which is relatively simple; And heavy, not suitable for installation and handling. Pay attention to the smoothness of the glaze, pay attention to tiny cracks and flaws, and never buy a cast iron cylinder with orange peel on the surface. Folding: the cylinder material of folding bathtub: double-layer waterproof cloth with sponge as the cylinder, the thickness of sponge ≥5mm, and the waterproof cloth is brightly colored. There are no wrinkles and cracks on the surface, and the zipper can be pulled back and forth freely. Folding bracket: The load-bearing bracket is composed of stainless steel square tubes of 25mm×25mm and 22mm×22mm, and the upper opening is composed of stainless steel cylindrical tubes of 20 ~ 22mm, with a smooth surface and a part that can be folded freely. Backboard: welded by stainless steel round pipe or square pipe, which can rotate freely and be fixed firmly. Waterproof breaking force: ≥450N/50mm, elongation at break: ≥ 15%. The folding bathtub has applied for the national utility model patent.

Ceramic bathtubs were eliminated because of their bulkiness, waste of materials and fragility, and were replaced by materials such as acrylic, cast iron enamel and steel plate enamel. The surface of acrylic material is polymethyl methacrylate, and the back is resin gypsum and glass fiber to enhance load bearing. The thickness is generally 3 ~ 10 mm, and its advantages are easy molding, slow heat dissipation, good thermal insulation performance, long water temperature, no cold feeling when touching its surface, warm touch, easy scrubbing and cleaning, light weight, convenient installation and rich color changes. Because of the above characteristics, acrylic bathtubs are cheaper. The disadvantage of this material is that it is easy to hang dirty and not wear-resistant. After a period of use, the surface is easy to appear gray. The steel plate bathtub is made of a certain thickness of steel plate and then plated with enamel. Features: easy molding and low cost. Because its surface is enamel, it is not easy to hang dirty, easy to clean, not easy to fade, and its luster is lasting.
