Generally, untreated bamboo has an average life of less than 1 year [1]. In case a scratch occurs, every type of bamboo countertop is easy to re-sand and re-seal. Even the weight of a heavy chair will usually not be enough to cause divots or cracks. Mold resistance of bamboo treated with copper complexes-grafted silica gel and its microdistribution in treated bamboo. When compared to hardwood, bamboo is slightly more resistant to water damage. The SEM images present a clear micro-morphology of the characteristics of both treated and untreated bamboo (Fig. The distributions of copper and silicon, which included onto the surfaces and in the insides of the bamboo specimens were determined. A new shoulder appeared for HSM-treated bamboo at about 3300 cm−1, due mainly to the stretching of O–H (hydrogen bonds) in bamboo biopolymers. It is best to have professional come and help you with tiles. 5. This process should lead copper to penetrate deeply into bamboo. CuCl2 was purchased from Tianjin Guangfu Technology Development Co. Ltd. (China). Mold growth was recorded every week. As these insects feed, they excrete a sticky substance called honeydew. The poor mold resistance of moso-bamboo filled composites could be the result of a combination of positive effects due to anti-fungal components and negative effects due to 5-hydroxymethylfurfural. And in most cases it is best to call in a plumber so that you can get a professional opinion on what is good and what is bad for your bathroom. Google Scholar, Mahr MS, Hübert T, Stephan I, Bücker M, Militz H (2013) Reducing copper leaching from treated wood by sol–gel derived TiO2 and SiO2 depositions. About 20 ml of molten PDA was poured into each petri dish (100 mm in diameter and 20 mm in height). The copper anchored sol system solution contained TEOS, APTES, EtOH, CuCl2, and purified water in appropriate ratios. Figure 6 shows a representative SEM image of the surface and the relevant X-ray spectrum with the relative atomic percentages, and the elemental composition in vessels (Fig. a Cross section of untreated bamboo; b longitudinal section of untreated bamboo; c cross section of HSM-treated bamboo; and d longitudinal section of HSM-treated bamboo.
