(Correspondent zhangyan and Correspondent Zou Wei) The Municipal Quality Supervision Bureau recently announced "the results of sampling inspection of the quality of some home decoration pollution sources in 2018". Among them, the qualified rate of interior wall coating is 86.7, the qualified rate of adhesive is 93.3, the qualified rate of diatom mud and wallpaper glue is 100, and the compliance rate of risk monitoring of sewing agent products is 97.5.
Chen Zhuqing, an engineer of the National Building Materials Product Quality Inspection Center (Nanjing) of the Municipal Quality Inspection Institute entrusted with the inspection, said that the interior wall paint is latex paint for general decoration. A total of 30 batches were sampled, and 4 batches were unqualified. The unqualified items were: scrubbing resistance. The performance of the products of Xuanwei and Caizhou brands in this sampling inspection is far lower than the national standard requirements. The scrub resistance project is an important quality index of latex paint, which reflects the density and powder resistance of the paint film surface. The poor amount of wash-resistant properties will cause wall delamination, powder falling, etc. Some enterprises in order to reduce the cost, reduce the amount of emulsion and titanium dioxide, choose cheap quality emulsion or reduce the amount of emulsion added, resulting in scrubbing resistance is not qualified.

In everyday life, we sometimes encounter cases of homonyms. During casual conversation, when referring to people with the same name, we have to add prefixes or suffixes for clarification; otherwise, it becomes unclear who we’re talking about. This phenomenon isn’t unique to Chinese speakers—after frequent exchanges between Chinese and foreign literary and artistic works, the prevalence of names like Tom, Jimmy, and David in overseas media has led us to realize that this is a global challenge.
Application of Quick-Install Wall Panels in Public Building Renovation
In the previous article, we discussed material selection for quick‑install wall panels. The key is to stay true to your needs—not necessarily opting for the absolute best materials, but choosing what suits you most. Of course, if you’re rolling in cash and want it all, no one will object. In this piece, let’s talk about installing these panels. Today, renovating public buildings typically begins with removing the existing finishes, which are often ceramic tiles or painted walls. Over time, the surfaces accumulate layers of wear and tear, and seeing them can become increasingly frustrating. Renovation isn’t just about cosmetic makeovers; more often than not, it aims to refresh the mood of those who spend time inside.
Application of Quick-Install Wall Panels in Public Building Renovation (Material Selection)
Many public buildings are quite old and no longer meet current requirements, facing the need for renovation or remodeling. The construction materials used under the historical conditions of their time—such as ceramic tiles applied to walls as cladding panels or plasterboard suspended ceilings in common areas—now reveal drawbacks when viewed through a modern lens: wet‑process methods are time‑consuming and costly, and routine maintenance of overhead services is inconvenient. As a result, many owners prefer to renovate using prefabricated wall panels and ceilings, which allow ongoing operations during the upgrade by renovating one area at a time without disrupting daily business. This section introduces the application of quick‑install wall panels in building renovations.
The Supporting Role in Wallboard Systems: Metal Trim Strips—Essential Yet Often Overlooked
Let’s start with the conclusion: when choosing decorative wall panels, our attention often focuses on the panel itself—whether it features wood grain, stone texture, or fabric patterns; whether the color palette leans toward light tones or darker shades; and how different colors can be coordinated. Meanwhile, metal trims used to cover joint gaps or corner transitions are easily overlooked, resulting in a final outcome that falls short of expectations. Why does this happen? Consider this scenario: in large‑area spaces like public corridors where wall panels are installed, if exposed trim strips are used, our gaze tends to be drawn to those strips, visibly fragmenting the wall’s overall cohesion. In essence, we end up noticing only the trim and overlooking the panels themselves.
