Description
本発明は、製紙工程における抄紙工程及び脱水工程の汚れ防止剤組成物及び汚れ防止方法に関し、更に詳しくは抄紙工程のワイヤーパートで使用されるワイヤー、脱水工程のプレスパートで使用される抄紙用フェルト及び各種プレスロールに対する有機汚れ・無機汚れの付着、堆積を防止し、ワイヤーパート及びプレスパートを清浄に保持するための汚れ防止剤組成物及び汚れ防止方法に関する。 The present invention relates to an antifouling agent composition and a stain prevention method for a papermaking process and a dewatering process in a papermaking process, and more specifically, a wire used in a wire part of a papermaking process, and a felt for papermaking used in a press part of a dewatering process. The present invention also relates to an antifouling agent composition and an antifouling method for preventing adhesion and accumulation of organic dirt and inorganic dirt on various press rolls and keeping the wire part and press part clean.
製紙工程は、パルプ調製、抄紙、脱水、乾燥等の工程から成り立っている。抄紙工程ではワイヤーパートでパルプから大部分の水を取り去り湿紙とするが、この湿紙は、なお多くの水分を有している。このまま加熱乾燥すると多量の蒸気を必要とするので、脱水工程のプレスパートでプレス脱水してから乾燥工程へ送られる。プレスパートは、上下２段のロールからなるプレスロールと、湿紙を運搬する抄紙用フェルトの組み合わせからなり、該フェルトに載せられた湿紙はロールの間を通してプレス脱水される。プレスにおける脱水性は、抄紙用フェルトの搾水性に大きく依存しており、該フェルトに汚れが付着し目詰まりがあると、脱水が充分に行われず、また均一な脱水が出来ないため、乾燥工程での蒸気の増大や脱水工程での紙切れの原因となる。従って、抄紙用フェルトを常に清浄な状態に保つことが生産性を増大させる上で極めて重要である。 The papermaking process consists of processes such as pulp preparation, papermaking, dehydration, and drying. In the papermaking process, most of the water is removed from the pulp at the wire part to make a wet paper, which still has a lot of water. If it is heated and dried as it is, a large amount of steam is required, so it is dehydrated by the press part of the dehydration process and then sent to the drying process. The press part is composed of a combination of a press roll composed of two upper and lower rolls and a papermaking felt for transporting wet paper, and the wet paper placed on the felt is press-dehydrated between the rolls. The dewaterability in the press depends greatly on the water squeezability of the papermaking felt, and if the felt is clogged and clogged, the dewatering will not be performed sufficiently, and a uniform dewatering will not be possible. This causes an increase in steam and a piece of paper in the dehydration process. Therefore, it is extremely important to keep the papermaking felt always clean in order to increase productivity.
抄紙用フェルトに付着する汚れは、製紙原料及び製紙用添加剤に由来したものであり、有機汚れと無機汚れに大別される。有機汚れは、木材樹脂由来の樹脂酸、脂肪酸、不ケン化物や、製紙用添加剤に由来するパルプへ定着しなかったサイズ剤、紙力剤、歩留向上剤等が挙げられる。無機汚れとしては硫酸アルミニウムに由来する水酸化アルミニウムや、炭酸カルシウムなどの無機塩、カオリン、クレー、タルク、酸化チタンなどの填料成分が挙げられる。更に、近年の古紙利用増加に伴い抄紙工程内に持ち込まれる頻度が高くなった接着剤、ラテックス、インクビヒクル等も抄紙用フェルトの汚れを助長させている要因である。 The stains adhering to the papermaking felt are derived from the papermaking raw materials and the papermaking additives, and are roughly classified into organic stains and inorganic stains. Examples of organic stains include resin acids derived from wood resins, fatty acids, unsaponifiable materials, and sizing agents, paper strength agents, and yield improvers that have not been fixed to pulp derived from papermaking additives. Examples of inorganic stains include aluminum hydroxide derived from aluminum sulfate, inorganic salts such as calcium carbonate, and filler components such as kaolin, clay, talc, and titanium oxide. Furthermore, adhesives, latex, ink vehicles, and the like, which have been frequently introduced into the papermaking process with the increase in the use of used paper in recent years, are factors that contribute to soiling of papermaking felt.
このような状況において抄紙用フェルトの搾水性低下をもたらす水酸化アルミニウムや炭酸カルシウムのような無機汚れを防止する方法として、例えば特許文献１にはキレート作用のあるクエン酸、リンゴ酸、酒石酸等の有機酸を単独または塩酸、硫酸、スルファミン酸等の無機酸を混合した洗浄液を利用することが提案されている。 In such a situation, as a method for preventing inorganic stains such as aluminum hydroxide and calcium carbonate, which cause a decrease in the water squeezability of papermaking felt, for example, Patent Document 1 discloses chelating citric acid, malic acid, tartaric acid and the like. It has been proposed to use a cleaning solution in which an organic acid is used alone or an inorganic acid such as hydrochloric acid, sulfuric acid or sulfamic acid is mixed.
又、有機汚れを防止する方法として、例えば特許文献２にはピッチ類等の有機汚れに対してポリオキシアルキレンエーテル系溶剤とアルキルポリオキシエチレンリン酸エステル系界面活性剤を混合した洗浄液の利用が提案されている。 As a method for preventing organic stains, for example, Patent Document 2 discloses the use of a cleaning liquid in which a polyoxyalkylene ether solvent and an alkylpolyoxyethylene phosphate ester surfactant are mixed with organic stains such as pitches. Proposed.
更に、抄紙用フェルトに障害を引き起こす実際の汚れは有機汚れ、無機汚れが各々単独ではなく複合化しているとの観点から、木材樹脂由来の樹脂酸、脂肪酸あるいはサイズ剤等の有機汚れと炭酸カルシウム等の無機汚れの双方に対応する方法として、例えば特許文献３にはカルボン酸と非イオン性界面活性剤の組合せ、特許文献４には水溶性ポリマーと脂肪族アミン又はその誘導体との組合せが提案されている。 Furthermore, from the viewpoint that the organic soil and the inorganic soil are combined, not the sole soil, but the organic soil such as resin acid, fatty acid or sizing agent derived from wood resin, and calcium carbonate are the actual soil that causes the papermaking felt. For example, Patent Literature 3 proposes a combination of a carboxylic acid and a nonionic surfactant, and Patent Literature 4 proposes a combination of a water-soluble polymer and an aliphatic amine or a derivative thereof. Has been.
しかしながら、従来知られているこれらの薬品を単独あるいは併用しても有機汚れと無機汚れを同時に防止することが困難であり、更に抄紙機の高速化、製紙用添加剤の多様化、製紙原料の変化に対応した更なる改善が要望されている。 However, even if these conventionally known chemicals are used alone or in combination, it is difficult to prevent organic stains and inorganic stains at the same time. Further, the speed of paper machines, the diversification of papermaking additives, There is a need for further improvements in response to changes.
