There are a lot of environmentally friendly bathroom products, how to identify stumped consumers-Environmental sanitary ware, identification

Mr. Zhang: My home has just been renovated for a month, but the white latex paint on the walls has cracks. I don't know why, and what can be done to remedy it? Relevant people answering questions: There are several reasons for this: cracks caused by the pressure of the building wall; cracks in the gap between the wall insulation board and the board; too thick putty in the construction of the base material, and too much wind in spring and autumn, causing cracks; wiping Stress cracks caused by uneven putty scraping; shrinkage cracks caused by slotting in the wall and ash filling in the wire groove; of course, if the original wall is not handled well, and there is no putty scraping, it is easy to cause cracks. Structural cracks cannot be repaired. If it is only a surface crack, the remedy is to remove all the latex paint and the base layer with a width of 4cm with the crack as the center along the length of the wall crack (the cement wall should be seen), then whitewash the latex, and then scrape a Layer gypsum, paste caulking tape, scrape the putty twice, then polish, and finally do two topcoats. Ms. Wang: My solid wood floor has been laid for 2 years, and there are gaps between the boards. How can I eliminate these gaps? Relevant person Qu0026A: It is normal for gaps to appear after the solid wood floor is paved. The main components of wood, cellulose, hemicellulose and lignin, have hydrophilic groups. These hydrophilic groups present in the amorphous region of the wood cell wall absorb or desorb moisture under certain conditions, so that the size of the wood changes and gaps are formed. In winter, due to the dry weather, as long as a stable dry humidity is maintained, the floor will not be deformed. Consider using a humidifier to increase the air humidity, but avoid sprinkling water on the floor. Mr. He: I wanted to buy a set of bathroom products a few days ago. I saw a lot of merchants, and they all vigorously promoted the acrylic material, saying that it is environmentally friendly. How can we identify it? Relevant person answered questions: Acrylic is a better new material that can manufacture sanitary ware after ceramics. Compared with traditional ceramic materials, acrylic has incomparable high brightness, good toughness, large processing plasticity, exquisite style, durability, and environmental protection. Its radiation is almost the same as that of the human body's own bones. However, due to the shortcomings of poor high temperature resistance, poor pressure resistance and wear resistance, and easy aging of the surface of artificial agricultural production system materials, acrylic bathtubs are prone to discoloration after a long time of use. Acrylic production is difficult and costly. There are many low-quality and cheap substitutes on the market. They are actually ordinary agricultural production system boards or composite boards. The surface hardness of ordinary agricultural production system board is low, and it is easy to fade, and it is polished with fine sand. The composite board only has a thin layer of acrylic on the surface, and the middle is ABS plastic, which is easy to delaminate due to thermal expansion and contraction during use.
