Hierarchical Lamellar Aluminophosphate Materials with Porosity as Ecofriendly Inorganic Adhesive for Wood-Based Boards

“…There is a total weight loss of 32.99% for APIA. The first stage with the weight loss of 3.44% is caused by evaporation of moisture . Then, a total weight loss of 27.22% occurs at 130.3 and 153.1 °C, caused by the loss of interlayer water from the crystalline hydrate [AlH 3 (PO 4 ) 2 ·3H 2 O and AlH 3 (PO 4 ) 2 ·H 2 O] .…”

“…For fibers, three distinct weight loss stages are accounted for 7.41%, 58.52%, and 24.17%, respectively, which are attributed to the loss of free and chemically bonded moisture and the thermal dehydroxylation process. − Differently, the WBB has a lower total weight loss (45.13%) than the pure fibers. The weight loss for WBB also exhibits three distinct stages at 9.58%, 23.73%, and 11.82%, respectively.…”

“…The thermogravimetric (TG) analysis, which could be exactly recorded as the mass loss of the sample versus temperature, is well-established for online pyrolysis of wood fibers. 55 So, the TG and differential thermogravimetric (DTG) curves of APIA, pure fibers, and WBB subjected to heat in the range 25−600 °C are shown in Figure 6 and Figure S4. There is a total weight loss of 32.99% for APIA.…”

“…The first stage with the weight loss of 3.44% is caused by evaporation of moisture. 55 Then, a total weight loss of 27.22% occurs at 130. 23 The last stage of weight loss (2.33%) is a result of the thermal dehydroxylation process.…”

A Study on the Flocculation and Sedimentation of Iron Tailings Slurry Based on the Regulating Behavior of Fe3+

“…Dispersants can produce a high degree of dispersion for fine suspension; however, it does not help affect the PAM molecular structure and its adsorption on particles. Therefore, methods for the PAM degradation on the particles can be proposed, such as mechanical degradation by stirring or ultrasonic degradation [14], biodegradation [15], thermal degradation [16,17], photocatalytic degradation [18][19][20], and oxidative degradation [21,22], etc. Among them, the oxidative degradation is a universal and practical method using oxidizing agents, such as O 2 , Fenton agent, KMnO 4 , and some metal ions, producing reactive free radicals during redox reactions and then leading to linked oxidation reactions for degradation [23].…”
