Size presses on paper machines are used to apply a solution of a polymer – usually starch – to the surface of the sheet and thereby to increase the stiffness, surface strength, and printing quality of the product. This article reviews publications dealing with the size press equipment, the materials, and factors affecting both the operating efficiency and attributes of the resulting paper. The emergence of film-press equipment (e.g. blade-metering size presses) in the 1980s has greatly decreased the frequency of web breaks and increased productivity. Starch technology at the size press, though relatively mature, continues to evolve. By adjustment of starch attributes, solids levels, and incorporating other additives, modern papermakers can tune size press outcomes to meet a range of paper product requirements, including strength, hydrophobicity, and the reduction of air permeability. By application of various synthetic polymers, mineral particles, and even nanocellulose in combination with starch or other base polymers, there is potential to extend the technology to meet a range of future needs for paper products.
造纸机上的定径压榨用于将聚合物溶液(通常是淀粉)涂抹到纸页表面,从而提高产品的挺度、表面强度和印刷质量。本文回顾了有关压榨设备尺寸、材料以及影响操作效率和纸张特性的因素的出版物。20 世纪 80 年代出现的薄膜压榨设备(如刀片计量定径压榨机)大大降低了纸幅断裂的频率并提高了生产率。定径压榨的淀粉技术虽然相对成熟,但仍在继续发展。通过调整淀粉属性、固体含量和加入其他添加剂,现代造纸商可以调整压榨结果以满足一系列纸品要求,包括强度、疏水性和降低透气性。通过将各种合成聚合物、矿物微粒甚至纳米纤维素与淀粉或其他基础聚合物结合使用,该技术有可能得到扩展,以满足未来对纸制品的各种需求。

Both developed and developing countries around the world are increasingly utilizing biodegradable products and bio-based materials. This is required to curb rampant environmental pollution caused by synthetic materials and their by-products. In this study, banana and bamboo fibers were prepared from agricultural and industrial wastes, respectively. Banana and bamboo fibers were obtained with aid of mechanical and waste extractions, respectively. Both fibers were subjected to a retting process for 24 hours, using normal warm water at a room temperature (27 ± 3 °C) to remove the impurities. Then, a comparative investigation and analysis was conducted concerning their properties and applications. The biomass level, physical, and chemical properties, structure, experimental analysis, and moisture regain behaviors of the plant materials were studied. Additionally, the antibacterial property of the samples was discussed. The biomass level was measured per hectare for banana (36.1 tons) and per plant for bamboo (65%), and the physical and chemical properties were identified via some basic testing techniques. The molecular, crystalline, and morphology structures were observed using Fourier-transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy. Finally, the industrial applications were elucidated to establish the possibility of using both fibers as promising sustainable, renewable, recyclable, and eco-friendly materials.

Microwave (MW) treatment is an environmentally friendly and time-saving technique with great potential for generating wood-impregnation innovations. In this study, a microwave-assisted impregnation (MWAI) approach was developed to achieve adequate retention and fixing of alkaline copper quaternary (ACQ) in refractory spruce wood. The synergistic effect of MW pre- and post-treatments in the impregnation procedure on wood’s compressive strength (CS) and copper leaching resistance and valence conversion was investigated. In conclusion, high-intensity MW pre-treatment and low-intensity MW post-treatment provided optimum results for the fixation of copper. Based on the results of the copper conversion assays, the same MWAI procedure is also predicted to give high biological efficiency.

The dimensional stability and equilibrium moisture content (EMC) of thermally modified hardwoods were studied. Lumber of yellow-poplar (Liriodendron tulipifera); red oak (Quercus borealis); white ash (Fraxinus americana), red maple (Acer rubrum); hickory (Carya glabra), and black cherry (Prunus serotina) were modified in industrial thermo-vacuum system. The water absorption rate, EMC, swelling, anti-swelling efficiency, shrinkage, anti-shrinkage efficiency, and anisotropy of the specimens were measured and compared to unmodified wood. The results show that thermal modification significantly decreased water absorption of wood which leads to improved dimensional stability. Specifically, thermally modified wood showed reduced EMC (22% in hickory to 59% in red maple), increased water absorption repellent (14.9% in black cherry to 29.6% in yellow-poplar), increased anti-swelling efficiency (14.2% in hickory to 71.4% in ash), increased anti-shrinkage efficiency (23.5% in red maple to 65.6% in ash), and reduced anisotropy coefficient (4.7% in red oak to 31.9% in black cherry).
研究了热改性硬木的尺寸稳定性和平衡含水率(EMC)。在工业热真空系统中对黄杨(Liriodendron tulipifera)、红橡(Quercus borealis)、白蜡(Fraxinus americana)、红枫(Acer rubrum)、山核桃(Carya glabra)和黑樱桃(Prunus serotina)的木材进行了改性。测量了试样的吸水率、EMC、膨胀率、抗膨胀效率、收缩率、抗收缩效率和各向异性,并与未改性木材进行了比较。结果表明,热改性显著降低了木材的吸水率,从而提高了尺寸稳定性。具体来说,热改性木材的 EMC 值降低了(山核桃的 EMC 值降低了 22%,红枫的 EMC 值降低了 59%),吸水排斥率提高了(黑樱桃的吸水排斥率提高了 14.9%,黄杨的吸水排斥率提高了 29.6%),抗膨胀效率提高了(山核桃的抗膨胀效率提高了 14.2%,水曲柳的抗膨胀效率提高了 71.4%),抗收缩效率提高了(红枫的抗收缩效率提高了 23.5%,水曲柳的抗收缩效率提高了 65.6%),各向异性系数降低了(红橡木的各向异性系数提高了 4.7%,黑樱桃的各向异性系数提高了 31.9%)。

Fourteen different plant parts consisting of leaves, roots, flowers, and seeds were examined separately of Rumex patientia, Hyoscyamus niger, Melilotus officinalis, Lamium album, and Epilobium angustifolium plants. All of these are naturally growing and used for medicinal purposes in Kars province. Five different methods were used to determine the antioxidant capacity of these herbal products. The methods were as follows: determination of total polyphenol, total flavonoid, DPPH● (free radical), CUPRAC (cupric reducing antioxidant capacity), and FRAP (ferric ıon reducing antioxidant power). The data obtained regarding the antioxidant activity demonstrated that the flower part of the Epilobium angustifolium plant obtained from Kars had the highest antioxidant capacity. It was determined that the seeds of the Hyoscyamus niger plant had the lowest antioxidant capacity.

Impinging air jets can be used to dewater, heat, and dry the web of tissue paper. High velocities of the air jets degrade the paper, and appropriate adjustments to the jet velocity and the distance of the nozzle from the surface of the wet web are crucial to obtain the highest quality product. This work investigated the correlation between the velocity of the air jet and the strength of paper subjected to the impingement method. Papers with an initial moisture content of 20% and various pulp mixes were tested, and the physical properties of papers were explored. After impinging an air jet, different tensile strength limits were obtained in the machine and cross directions. The paper had lower apparent density and higher roughness compared to classical pressing. The dependence of tensile strength and roughness on the fibers composition also was determined. Increasing the amount of eucalyptus fibers in impingement dewatered paper resulted in a decrease in its tensile strength and roughness. The value of elongation before breaking was the highest for softwood papers after the impingement method. The maximum velocity of an air jet that can be used to dewater or dry paper without the risk of damage to the papers was determined.
喷射气流可用于卫生纸纸幅的脱水、加热和干燥。高速气流会使纸张变质,因此适当调整气流速度和喷嘴与湿纸幅表面的距离对于获得最高质量的产品至关重要。这项工作研究了气流速度与采用撞击法的纸张强度之间的相关性。对初始含水量为 20% 的纸张和各种纸浆混合进行了测试,并探讨了纸张的物理特性。在冲击气流后,纸张在机向和横向上获得了不同的抗张强度极限。与传统压榨法相比,纸张的表观密度更低,粗糙度更高。此外,还确定了抗张强度和粗糙度与纤维成分的关系。增加撞击脱水纸中桉树纤维的含量会降低抗张强度和粗糙度。采用撞击法后,软木纸的断裂前伸长率值最高。确定了可用于脱水或干燥纸张而不会损坏纸张的最大气流速度。

Wood structures generally rely on synthetic adhesives for their strength and versatility. However, environmental concerns linked to the chemical composition of these adhesives have stimulated the search for more environmentally friendly adhesives. Researchers have explored replacing petroleum-based constituents with natural raw materials such as lignins, tannins, and proteins. Of these alternatives, proteins, being biological macromolecules, are recognized for their capacity to enhance adhesion to wood substrates. This study considered the development of protein-based adhesives derived from diverse sources, including soybean meal, microbrewery spent grains, shrimp shells, and skim milk powder. These raw materials were subjected to mild alkaline conditions to yield protein concentrates. The resulting adhesives were formulated at various protein content levels: 5%, 10%, 15%, and 20%. The study’s findings showed that the incorporation of proteins into the polyurethane adhesive system not only can preserve but also augment adhesive performance. This enhancement encompasses deeper penetration into wood substrates and an overall improvement in mechanical strength. These results underscore the promise of proteins as a sustainable alternative to petroleum-based polyols in adhesive formulations.
木结构通常依靠合成粘合剂来获得强度和多功能性。然而,与这些粘合剂的化学成分有关的环境问题促使人们寻找更环保的粘合剂。研究人员探索用木质素、单宁酸和蛋白质等天然原料来替代石油基成分。在这些替代品中,蛋白质作为生物大分子,因其能够增强与木材基材的粘合力而得到认可。本研究考虑开发基于蛋白质的粘合剂,其来源多种多样,包括大豆粉、微酿酒厂废谷物、虾壳和脱脂奶粉。将这些原料置于弱碱性条件下可产生浓缩蛋白质。所得粘合剂的蛋白质含量分别为 5%、10%、15% 和 20%。研究结果表明,在聚氨酯粘合剂系统中加入蛋白质不仅能保持粘合剂的性能,还能提高粘合剂的性能。这种增强包括更深入地渗透到木材基材中,并全面提高机械强度。这些结果表明,蛋白质有望成为粘合剂配方中石油基多元醇的可持续替代品。

However, environmental concerns linked to the chemical composition of these adhesives have stimulated the search for more environmentally friendly adhesives. Researchers have explored replacing petroleum-based constituents with natural raw materials such as lignins, tannins, and proteins. Of these alternatives, proteins, being biological macromolecules, are recognized for their capacity to enhance adhesion to wood substrates. This study considered the development of protein-based adhesives derived from diverse sources, including soybean meal, microbrewery spent grains, shrimp shells, and skim milk powder. These raw materials were subjected to mild alkaline conditions to yield protein concentrates. The resulting adhesives were formulated at various protein content levels: 5%, 10%, 15%, and 20%. The study’s findings showed that the incorporation of proteins into the polyurethane adhesive system not only can preserve but also augment adhesive performance. This enhancement encompasses deeper penetration into wood substrates and an overall improvement in mechanical strength. These results underscore the promise of proteins as a sustainable alternative to petroleum-based polyols in adhesive formulations.","PeriodicalId":503414,"journal":{"name":"BioResources","volume":"141 32","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139453107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
