Abstract: In order to analyze the relation between surface roughness of Pyinkado plates and sanding parameters, an orthogonal experiment and a single factor experiment were performed. The results show that the mesh of the sandpaper has remarkable influence on surface roughness of Pyinkado plates, but the feeding speed and sanding thickness don’t; when the mesh of the sandpaper is 150, the feeding speed is 6 m/min and sanding thickness is 0..4 mm during the first sanding and the mesh of the sandpaper is 240, the feeding speed is 9m/min and sanding thickness is 0.15mm during the second sanding, the smallest roughness (Ra) was obtained as 2.81μm. Considering production efficiency, changing feeding speed into 9 m/min in the theory optimization scheme, engineering optimization scheme was obtained, and the wood surface roughness (Ra) is 2.91μm.

In order to analyze the relation between wood surface roughness of plantation- Magnoliaceae glanca Blume and sanding parameters, an orthogonal test and a single factor test were performed. The results show that the mesh of the sandpaper has remarkable influence on wood surface roughness of plantation-Magnoliaceae glanca Blumes, but the feeding speed and sanding thickness don’t; when the mesh of the sandpaper is 150, the feeding speed is 6m/min and sanding thickness is 0.6 mm during the first sanding and the mesh of the sandpaper is 320, the feeding speed is 9m/min and sanding thickness is 0.2mm during the second sanding, the smallest roughness (Ra) was obtained as 2.45μm. In the theory optimization scheme, changing feeding speed into 9 m/min with considering production efficiency and changing the mesh of the sandpaper into 240 with reducing consumption of the sandpaper, then engineering optimization scheme was obtained, and the wood surface roughness (Ra) is 2.70μm.

HighlightsThis article focuses on the sugarcane top chopper.The influence of three factors on the experimental indexes was studied.The optimal parameters combination of working performance was obtained.Abstract. In the process of sugarcane harvesting, sugarcane tops are cut off by the chopper and directly thrown into the field. A small percentage of sugarcane tops are picked and collected to feed livestock. Therefore, it is meaningful to develop an effective sugarcane top chopper which is used to harvest sugarcane tops before harvesting sugarcane stalk harvesting. In this study, a sugarcane top chopping platform was fabricated to investigate critical parameters such as chopping speed (CS), top feeding speed (FS), and cutting drum gap (DG) on the machine performance. In evaluating the sugarcane top chopper, three single factor experiment and one orthogonal experiment were carried out. The single factor test was used to examine the effect of CS, FS and DG on the chopping performance of the machine. According to orthogonal test, the comprehensive influence order was determined: cutting drum gap > chopping speed > top feeding speed. The optimal parameters combination for good working performance of the machine was obtained: chopping speed was 750 rpm, top feeding speed was 1.2 m·s-1, and cutting drum gap was 20 mm. The relationships between the chopping performance and the three critical factors were examined and analyzed to provide theoretical basis for the development of a sugarcane top chopper. Keywords: Chopping performance, Orthogonal test, Single factor test, Sugarcane top chopper, Variance analysis.

Photocatalyst of Fe-Sm-Yb modified TiO2 loaded on clay brick was prepared for degradation of NH3-N in coking water. The influence factors of NH3-N degradation rates were discussed by single factor experiment and orthogonal experiment. The optimum process conditions of photocatalytic degradation NH3-N in coking water were confirmed. The results show that NH3-N degradation rates 82.23% were highest in the conditions of pH 6.5, photocatalyst charge of 1.4 g, illumination for 6h, reaction at 55°C, calcination at 500°C.

In this study, we performed a single-factor experiment and an orthogonal experiment to evaluate different processing conditions during the extraction of polyphenols from grape skin using microwave-assisted ethanol extraction. In the study, we found that the best conditions for polyphenol extraction using microwave assistance were as follows: 50% ethanol (40 mL) was used to extract polyphenols from grape skin (1 g) while in a 540-W microwave for 3 min.

Laser polishing technology plays an increasingly important role in the material processing technology.In order to study the influence of scanning interval on the polishing effect of S136D die steel, the single factor experiment method is used in this paper. The continuous fiber laser is used to carry out many laser polishing experiments and the influence of laser scanning interval on the surface morphology of S136D die steel is analyzed.The results show that the surface roughness of polished samples decreases first and then increases with the of scanning interval. When the scanning interval is in the range of 0.03-0.1mm, the surface roughness of samples is relatively flat, and the lowest surface roughness can be reduced to 0.781μm, and the reduction rate of surface roughness can reach 90.2%.

NaClO is chosen as the best oxygen among Ca (ClO)2 and ClO2.The best experimental factors were achieved through the single factor experiment and orthogonal experiment, according to these factors, the actual wastewater project was verified. The results showed that the removal rate of ammonia-nitrogen was above 90% when the matter amounts rate was 2:7, pH=9 and the react time was 60min. Considering the operation cost, the best reaction parameters were that the matter amounts rate was 2:3, pH=7 and the react time was 30min in the actual wastewater project.
