Ating was scratch having a thin blade, and then the scratch adjustments at 1 d, three d, 7 d and 14 d were observed by Zeiss Axio scope A1 biological microscope (OM, Zeiss optical instruments International Trade Co., Ltd., Shanghai, China). The rough test was tested by fine roughness tester J84C (Shanghai Taiming Optical Instrument Co., Ltd., Shanghai, China). The coated wood board was placed around the test bench, and the probe was moved to speak to the wood board. Just after adjusting the probe position to ensure its stability at coordinate 0, the roughness was detected and recorded. All the tests were repeated four occasions, and also the error was inside 5.0 . three. Benefits and Discussion three.1. Evaluation of Microcapsule Morphology and Composition The SEM morphology of microcapsules with and without the need of rice husk powder was analyzed as shown in Figure 1. Tetrahydrozoline supplier Compared with Figure 1A, the microcapsules with rice husk powder content of five.five , which was showed in Figure 1B, had tiny agglomeration, good morphology, and uniform particle size. In Figure two, the absorption peak at 1547 cm1 belongs to NH stretching vibration peak, that is the characteristic peak of melamine resin. Compared together with the microcapsules with out rice husk powder, the Hymeglusin Anti-infection infrared spectrum on the microcapsules with rice husk powder inside the wall material split at 1157 cm1 , plus the peak variety changes. It could be inferred that this peak is affected by the CH vibrationresin. Compared using the microcapsules without having rice husk powder, the infra longs to NH stretching vibration peak, which is the characteristic peak of melamine of the microcapsules with rice husk powder in the wall material split at 1157 resin. Compared together with the microcapsules without rice husk powder, the infrared spectrum peak type modifications. It could be inferred that this peak is affected by the CH from the microcapsules with rice husk powder inside the wall material split at 1157 cm1, and the aromatic core plus the COC antisymmetric “bridge” stretching of 19 Appl. Sci. 2021, 11, 8373 six vibration peak kind modifications. It may be inferred that this peak is affected by the CH vibration of husk powder, and it could be judged that the wall material of microcapsule c aromatic core along with the COC antisymmetric “bridge” stretching vibration peak in rice drop. The absorption peaks at other positions of microcapsules with 5.5 rice husk powder, andof aromatic core and also the COC antisymmetric “bridge” stretching vibration peak incelluit is usually judged that the wall material of microcapsule consists of rice inside the infrared spectra are constant using the microcapsules without rice h shed.

The the infrared spectra are constant using the microcapsules with no The chemical composition of your microcapsules has has not changed, so it it may concluded that not changed, so is usually be concluded chemical composition in the microcapsules that the microcapsules are successfully ready. the microcapsules are effectively ready.Figure 1.
