摘要： Dans la fabrication du papier à partir d'une pâte aqueuse de fabrication de papier, un liant comprenant de l'acide silicique colloïdal et de la gomme de guar est ajouté à la pâte pour améliorer le papier ou la rétention des composants de la pâte de manière à réduire les problèmes de pollution et la quantité de substances précieuses dans l'eau blanche. La gomme de guar est amphotérique ou de préférence cationique et peut faire partie du complexe liant dans un mélange avec de l'amidon cationique. Le rapport des poids entre la gomme de guar et SiO2 ou entre la gomme de guar plus l'amidon cationique et SiO2 est compris entre 0,1:1 et 25:1.

摘要： Paper making process with improved retention and binding of fillers and second grade fibers. It is characterized by the use of an amphoteric mucous like compound as binder. This compound is the reaction product between cationic starch of low charge density and an anionic polymer of high charge density as carboxymethyl cellulose. The compound has amphoteric and mucous characters and should be used for paper making, while in a unique transient structure. This structure is characterized by filler particles being enclosed and finely distributed in droplets of the highly hydrated but substantially water-insoluble mucous compound. According to the invention this transient structure may further be reorganized to a less hydrated and more resistant gel structure, still enclosing the filler. This gel structure can stand the draining forces on a paper machine wire. This structural reorganization is achieved by reaction with colloidal inorganic polymers of very high surface charge as polysilicic acid and polyaluminium compounds. The process yields papers of high strengths and filler retentions of more than 90% at a single fire passage even at extreme filler contents of 30-60% of the paper weight.

摘要： Method of sizing paper and, in particular, paper made under neutral to alkaline conditions at least as high as 10.5. The papermaking stock is first treated with a polycationic material to provide sizing receptive sites uniformly distributed over the fiber surface. The presence of the anchoring points is critical to the later redistribution of the sizing material in the dryer section of the paper machine. The sizing material is then added to the slurry. This is then brought down onto the fibers by addition of a small amount of a size precipitant such as alum. The sizing molecule should have a hydrophilic portion with two hetero atoms forming a bidentate analog structure. This must have a pK in water of 6.0 or higher and a vapor pressure preferably at least 0.0006 mm Hg at 60 DEG C. The polycationic material provides anchoring/orienting sites on the fiber to which the small globules of sizing attach when the emulsion is broken by the precipitant. Sizing will develop in the dryer section of the paper machine, presumably by vapor phase redistribution of sizing from the attached globules to unfilled sites where an anchoring point is present. Alkyl and alkenyl substituted catechols, beta-diones, hydrozamic acids and imides are among the new classes of sizing materials disclosed.
摘要翻译：纸张尺寸的方法，特别是在中性至碱性条件下至少高达10.5的纸张。首先用聚阳离子材料处理造纸原料，以提供均匀分布在纤维表面上的施胶接收位点。锚定点的存在对于造纸机的干燥器部分中的上浆材料的后续再分配至关重要。然后将上浆材料加入浆料中。然后通过加入少量的大小沉淀剂（例如明矾）将其还原到纤维上。上浆分子应具有亲水部分，其中两个杂原子形成双齿模拟结构。在60℃或以上的水中必须具有pK，在60℃下蒸气压优选至少为0.0006mmHg。聚阳离子材料在乳液破碎时附着的小尺寸颗粒附着的纤维上提供锚定/取向位点由沉淀物。造纸机的烘干部分会发生尺寸变化，可能是通过气相重新分配尺寸从连接的小球到存在锚定点的未填充部位。烷基和链烯基取代的邻苯二酚，β-二酮，氢化唑和酰亚胺是公开的新型施胶材料之一。

摘要： New process for preparing a fiber sheet by using paper techniques, with a pH comprised between 6.2 and 9.5, from fibers, an organic polymer binder, an organic cationic flocculant and an agent reducing the adherence of the sheet to the wet presses during the formation of the sheet. The sheet obtained according to said method, of which the pH of the aqueous extract is higher than 7, and which exhibits improved mechanical properties particularly as to the tensile strength, the bursting resistance, the impact resistance, the rupture energy and the machinability, is useful in the packaging field and particularly for paper bags.

摘要： In a new process for reducing the density, increasing the bulk, the hand and the porosity of a sheet material containing fibres by means of a vegetable filler, a vegetable filler of density less than 500 kg/m is introduced into the fibrous mass during the manufacture of the material. At least 95 % of the particles of the vegetable filler are less than 150 micrometres in size and at least 80 % of said particles are greater than 10 micrometres in size. The process is particularly useful for obtaining paper and cardboard of low density with improved hand and porosity. It is also attractive since it reduces the cost prices and enhances the thermal and acoustic insulation properties.

摘要： A process for preparing a sheet with improved stiffness by mixing a fiber, a latex having minimum film-forming conditions greater than the conditions the sheet reaches during drying and a fugitive coalescing agent. The mixture is collected and dried under conditions less than the minimum film-forming conditions of the latex. The process enables hard latexes to be employed which do not form films under the drying conditions of the sheet whereby the hard latexes can contribute to the stiffness of the final sheet. A sheet prepared by the process is also provided.
