Three methods of activated carbon incorporation on paper are carried out to evaluate the paper’s physical parameters and adsorption ability to ethylene. The paper’s physical parameters include grammage, bursting strength, Ring Crush Test (RCT), moisture content, water absorption (Cobb60), and paper microstructures using SEM. Evaluation of the performance of activated carbon paper nanopores as ethylene adsorbent is conducted using GC. The treatment of activated carbon nanopores on non-wood paper causes grammage to increase, but RCT and paper bursting strength decrease. The incorporation of nanopore-activated carbon by the mixing method has produced papers with activated carbon particles spread evenly inside the pulp fibers of the paper. Activated carbon paper with the best adsorption capacity is bamboo+KMnO4&mixing with an adsorption capacity of 1,348 ppm and ethylene amount of 88.58 %. Concentration equilibrium is reached in the 25th minute. The non-linear pseudo-first-order absorbent kinetics model is an appropriate model to describe the equilibrium capacity of ethylene entrant (qe) by nanopore-activated carbon paper with the equation: qt = 1.35734 ( 1 − exp − 0.15312 t ) mathrm{qt}=1.35734hspace{0.1667em}(1-{exp ^{-0.15312hspace{0.1667em}mathrm{t}}}) , with R 2 = 0.9981 {mathrm{R}^{2}}=0.9981 .","PeriodicalId":19315,"journal":{"name":"Nordic Pulp & Paper Research Journal","volume":"38 1","pages":"121 - 130"},"PeriodicalIF":1.2,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47143319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is more and more widely used in forming packaging containers. The current research on mechanical performance and inelastic deformation of paperboard mainly focus on its physical properties and simplified single-blank forming, but the studies on the forming limit diagram (FLD) of paperboard are relatively rare. In this paper, Nakajima tests have been carried out to determine the FLD curves of the polyethylene-coated paperboard blank along the machine direction, cross direction, and diagonal direction. A laminated stamping method for multi-blank is proposed and investigated by experiment and numerical simulation. Up to 5 blanks can be overlapped and stamped in a single punch stroke, and 5 bowl-shaped packaging containers can be formed simultaneously. Compared with the single-blank stamping process, the production efficiency can be greatly improved, but the flange area of the forming parts is easier to wrinkle. However, the wrinkling risk can still be controlled by optimizing the process parameters, such as friction factor and blank holder gap.","PeriodicalId":19315,"journal":{"name":"Nordic Pulp & Paper Research Journal","volume":"38 1","pages":"157 - 169"},"PeriodicalIF":1.2,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48307024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An ultrafiltration pilot plant was used. Laboratory analyses were performed for the feed, permeate and retentate. Flux and transmembrane pressure (TMP) data were obtained from the pilot plant database. There were an average color and COD removals of 38 % and 39 %, respectively, for the EP-effluent and 58 % and 67 %, respectively for the white water; and a high turbidity and TSS removal (above 98 %) for both effluents. Substantial metals removal such as sodium, potassium, calcium, iron, magnesium and manganese was achieved. Some possibilities to reuse were considered: return to the water treatment plant, cooling of the digester bottom, equipment cooling, reuse in evaporation surface condensers. The use of ultrafiltration for the treatment of the alkaline effluent from the bleaching EP-stage and white water can be an interesting option.","PeriodicalId":19315,"journal":{"name":"Nordic Pulp & Paper Research Journal","volume":"38 1","pages":"171 - 179"},"PeriodicalIF":1.2,"publicationDate":"2022-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41475836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using high-boiling solvents, experiments can be done under atmospheric conditions, thus making it easier to continually monitor laboratory experiments and extracting aliquots at desired intervals. Using such a system, alkaline consumption was monitored during impregnation of spruce chips in glycerol media using chemical charges of 1 M NaOH and 0.1 M NaHS, i. e., kraft pulping conditions, and compared to a similar investigation of alkaline consumption in water media using steel autoclaves. The resulting data was fitted to a first order kinetic model, with an apparent activation energy of 22 kJ mol−1 in glycerol media. Finally, a “normal quality pulp” of kappa number 28 and a viscosity of 1113 ml g−1 was successful produced using a cooking process with an impregnation step at 140 °C for 3 h and a cooking step at 160 °C for 4 h. A nuclear magnetic resonance study on the dissolved lignin produced for said experiment showed characteristics typical of other kraft lignins.","PeriodicalId":19315,"journal":{"name":"Nordic Pulp & Paper Research Journal","volume":"38 1","pages":"9 - 18"},"PeriodicalIF":1.2,"publicationDate":"2022-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44582539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a museum, special measurements are adopted to avoid these damages, but for common households, a functional coating is a good solution. However, this is not an easy task as the coating must be removable and cannot damage the articles. Graphene oxide (GO) has the potential as ultraviolet shielding material for the protection of paper-based artifacts, but the application of monolithic GO coatings on paper-based artifacts is difficult. In this work, feasible GO/polyacrylonitrile composite films were prepared and their protection properties for rice paper were explored experimentally. When GO loading reached 2 %, the UV-A and UV-B blocking percentages of the film were 57.47 % and 70.86 %, respectively, with a visible light transmittance of 77.09 %. These films also performed good moisture resistance. With a good flexibility, they could be easily transferred onto and peeled off the rice paper surface without damaging the paper texture and patterns on it. These films basically meet the demand of paper-based artifacts protection.","PeriodicalId":19315,"journal":{"name":"Nordic Pulp & Paper Research Journal","volume":"38 1","pages":"111 - 119"},"PeriodicalIF":1.2,"publicationDate":"2022-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47377383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Measuring adhesive penetration depth has been limited to cross-sectional images, but quantifying the depth of penetration is difficult from these images. No quantitative method is well established in the literature. Four different techniques are compared to quantitatively measure adhesive penetration depth. Two methods involve separating the paperboard from the adhesive layer. Two other methods use of silicone oil penetration and mercury porosimetry to measure the decrease of pore volume after the adhesive is applied. These methods are compared with samples generated for various parameters. Experiments were conducted using a typical hot melt glue on uncoated and coated paperboard sample. Cross-sectional images from Scanning Electron Microscopy (SEM) confirm the penetration of some samples. The accuracy and repeatability of these methods were compared. Because of some issues with trying to repeatably remove the paper layer for the weight and thickness methods, and the time and cost of the mercury porosimeter method, the silicone oil method is a nice method to characterize the adhesive penetration depth.","PeriodicalId":19315,"journal":{"name":"Nordic Pulp & Paper Research Journal","volume":"38 1","pages":"147 - 155"},"PeriodicalIF":1.2,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43245246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Print quality was measured by testing with parameters such as delta gloss 60°, print lightness, print chroma, print density. As a result of the tests determined for print quality; print density values were low in A4 office papers with high roughness and porosity values, and the specular gloss values of the samples decreased in both printing applications. In electrophotographic printing; it was determined that darker colors formed with print lightness parameter, and the color scale increases in two-sided printing with print chroma values. It was determined that the color scale of print chroma values increased in two-sided prints.
