The emergence of cooling technology has brought huge social benefits to society, but it is also accompanied by the serious problem of energy consumption. In countries close to the equator,...

Carboxylated styrene‐butadiene latex (XSBL), attributed to its insufficient adhesion and poor water resistance, cannot be widely popularized in the adhesive industry. Herein, a novel XSBL‐based resin with high‐strength yet water‐resistant was reported, in which the butadiene macromolecular chains were grafted with acrylonitrile (AN) and acrylic acid‐2 hydroxyethyl ester (HEA) molecules, the crosslinking sites were esterified and expanded to construct a branched network structure, and the matrix was filled with nano‐SiO2 particles treated by blending silane coupling agents. We show that the new resin, having a dual curing mechanism at low and high temperatures, can be glued under different conditions. At room temperature, the sample group with a doping level of 1.33 wt% could achieve an overload shear strength of 3.17 MPa after curing, which is 233.7% higher than the XSBL; in the high temperature curing regime, the glue strength reached 1.21 MPa, much higher than the standard for the use of GB Class I plywood (≥0.7 MPa). The physicochemical properties meet the requirements for potential industrialization, for which the property–structure relation has been extensively explored. Further DSC and TG tests provide evidence for their wide application in the hot pressing process of man‐made plywood.

With the recent revolution in the green economy, agricultural solid waste resource utilization has become an important project. A small-scale laboratory orthogonal experiment was set up to investigate the effects of C/N ratio, initial moisture content and ll ratio (v cassava residue : v gravel ) on the maturity of cassava residue compost by adding Bacillus subtilis and Azotobacter chroococcum. The highest temperature in the thermophilic phase of the low C/N ratio treatment is signi cantly lower than the medium and high C/N ratios. The C/N ratio and moisture content have a signi cant impact on the results of cassava residue composting, while the lling ratio only has a signi cant impact on the pH value and phosphorus content. Based on comprehensive analysis, the recommended process parameters for pure cassava residue composting are a C/N ratio of 25, an initial moisture content of 60%, and a lling ratio of 5. Under these conditions, the high-temperature conditions can be reached and maintained quickly, the organic matter has been degraded by 36.1%, the pH value has dropped to 7.36, the E4/E6 ratio is 1.61, the conductivity value has dropped to 2.52 mS/cm, and the nal germination index increased to 88%. The thermogravimetry, scanning electron microscope, and energy spectrum analysis also showed that the cassava residue was effectively biodegraded. Cassava residue composting with this process parameter has great reference signi cance for the actual production and application of agriculture.

With the recent revolution in the green economy, agricultural solid waste resource utilization has become an important project. A small-scale laboratory orthogonal experiment was set up to investigate the effects of C/N ratio, initial moisture content and fill ratio (v cassava residue: v gravel) on the maturity of cassava residue compost by adding Bacillus subtilis and Azotobacter chroococcum. The highest temperature in the thermophilic phase of the low C/N ratio treatment is significantly lower than the medium and high C/N ratios. The C/N ratio and moisture content have a significant impact on the results of cassava residue composting, while the filling ratio only has a significant impact on the pH value and phosphorus content. Based on comprehensive analysis, the recommended process parameters for pure cassava residue composting are a C/N ratio of 25, an initial moisture content of 60%, and a filling ratio of 5. Under these conditions, the high-temperature conditions can be reached and maintained quickly, the organic matter has been degraded by 36.1%, the pH value has dropped to 7.36, the E4/E6 ratio is 1.61, the conductivity value has dropped to 2.52 mS/cm, and the final germination index increased to 88%. The thermogravimetry, scanning electron microscope, and energy spectrum analysis also showed that the cassava residue was effectively biodegraded.
