Abstract
Description
本発明は、製紙法を使った、地球環境にやさしい多機能型有機マルチシートの製造方法に関する。 The present invention relates to a method for producing a multifunctional organic multi-sheet that is friendly to the global environment using a paper manufacturing method.
地面を被覆する農業用マルチシートは地面の温度を向上させ、保湿し、肥料を減らし、雑草の生長を防止する等の作用によって農業の生産方法に変化をもたらし、その生産力を飛躍的に向上させた。現在では、根菜類などの野菜、苗圃、花卉、果物等の生産において多く利用されている。中国は１９７８年導入以来、マルチシートの使用面積は徐々に拡大されており、２００５年には既に９５．９万トンにも達した。使用面積は１３５３万ｈｍ２に達し、マルチシートを使用した栽培面積が世界最大の国となった。しかし、中国が現在使用しているマルチシートはポリエチレン（PE）やポリ塩化ビニール（PVC）であるため分子量が大きく、自然条件下での分解が困難で、しかも大量に使用しているマルチシートの厚さは０．０１２ｍｍ以下がメインであるために強度が弱く破れ易く、回収過程における工賃及び時間を浪費するうえリサイクルも難しく、土壌中への残留量が年々増加する故に、土壌構造を破壊し、土壌の浸透性を低下させ、深刻な白色汚染（テイクアウト用に使われる発泡スチロール製容器やビニール袋による）を引き起こし、再生利用不可能な有機化工原料を大量に消耗させている。そこで、マルチシートの長所を継承するのと同時に、マルチシートでは代替できない作用を備える、植物繊維から作られた紙製の農業用マルチシートが出現した。 Agricultural multi-sheets that cover the ground bring about changes in agricultural production methods by increasing the temperature of the ground, moisturizing, reducing fertilizer, preventing the growth of weeds, and dramatically improving its productivity. I let you. At present, it is widely used in the production of vegetables such as root vegetables, nurseries, flower buds and fruits. Since the introduction of China in 1978, the use area of multi-seat has been gradually expanded, and in 2005, it already reached 95.9 million tons. The use area reached 13.53 million hm2, and the cultivation area using multi-sheet became the world's largest country. However, since the multi-sheets currently used in China are polyethylene (PE) and polyvinyl chloride (PVC), they have a large molecular weight and are difficult to decompose under natural conditions. Since the main thickness is 0.012mm or less, the strength is weak and easy to tear, wastes labor and time in the recovery process and is difficult to recycle, and the residual amount in the soil increases year by year. It reduces soil permeability, causes severe white contamination (due to foamed polystyrene containers and plastic bags used for take-out), and consumes a large amount of organic chemical raw materials that cannot be recycled. Therefore, at the same time as inheriting the advantages of multi-sheets, paper-made agricultural multi-sheets made from plant fibers have emerged that have a function that cannot be replaced by multi-sheets.

しかし、現有する紙製農業用マルチシートの製造方法は、多少なりとも再生不可能な資源に関わっていたり、質的欠陥や技術上の複雑性が存在し、コストが割高である現状が見られる。よって、経済的で、地球環境にやさしく、リサイクル可能で、コストを削減できる原料の由来が何かを深く考えていくことが紙製農業用マルチシートを推進応用する場合に第一に考えなければならない課題である。 However, the existing method for producing paper multi-sheets for paper agriculture is related to resources that cannot be regenerated to some extent, or there are qualitative defects and technical complexity, and there is a current situation that costs are high. . Therefore, when promoting the application of paper multi-sheets for agriculture, we must first think about the origin of raw materials that are economical, environmentally friendly, recyclable, and capable of reducing costs. It is a problem that must not be done.
公知技術の中には存在する欠点に鑑み、本発明では、技術的に成熟した製紙法を使った、地球環境にやさしい多機能型有機マルチシートの製造方法を提供する。これによって、農業用マルチシートは、要求される機械強度、光透過性、通気性、保温性、保湿性或いはその他の特殊効果（殺菌消毒剤の添加、栄養元素の補充、肥料の放出制御等）を備えることができる。本発明で作製される紙製農業用マルチシートの特徴は、それの有する経済的で、地球環境にやさしい特性にあり、原料由来は、豊富、廉価、生分解性、土壌改良、時間及び工賃の節約等の特徴を有するものとする。 In view of the drawbacks existing in the known art, the present invention provides a method for producing a multifunctional organic multi-sheet that is friendly to the global environment, using a technically mature papermaking method.
