Abstract
Description
本発明は、マスク製造の技術分野に関し、特に５年間の使用期限を有するマスクの製造方法に関する。 The present invention relates to the technical field of mask manufacturing, and particularly to a method of manufacturing a mask having an expiration date of 5 years.
メルトブロー不織布のろ過性は主として静電吸着によるものであり、静電気の強弱はメルトブロー不織布の効率を決める。従来の製作技術で静電気を印加しない場合、ろ過布のろ過性は３０～５０％のみであり、静電気を印加したろ過性は９５％、９９％、さらにそれ以上に達することができる。それとともに問題もあり、静電減衰により、直接メルトブロー不織布の保存期間の短縮、又はマスクにした効率の低下を引き起こし、時間が長くなるほど多く減衰するので、マスクの使用期限が短縮される。 The filterability of the melt blow nonwoven fabric is mainly due to electrostatic adsorption, and the strength of static electricity determines the efficiency of the melt blow nonwoven fabric. When static electricity is not applied by the conventional manufacturing technique, the filterability of the filter cloth is only 30 to 50%, and the filterability to which static electricity is applied can reach 95%, 99%, or even higher. At the same time, there is a problem, and electrostatic damping directly causes a shortening of the storage period of the melt blown nonwoven fabric or a decrease in the efficiency of masking, and the longer the time, the more the damping, so that the expiration date of the mask is shortened.
現在、国際的にはコロナウイルスの予防治療状況が依然として非常に深刻である。マスクの通常の保存期間は２年間から３年間である。重要な国家戦略医療用備蓄物資として、より長い保存使用期限は、将来繰り返し変化する可能性のある疫病の流行状況において、肝心な役割を果たすことや、備蓄が早すぎて廃棄することによる資源の浪費を回避することが可能である。 Currently, the status of preventive treatment for coronavirus is still very serious internationally. The normal storage period for masks is 2 to 3 years. As an important national strategic medical stockpile, longer shelf life plays a crucial role in epidemic conditions that may change repeatedly in the future, and resources from stockpiling too early to dispose of. It is possible to avoid waste.
マスクの通常の保存期間は２年間から３年間であり、資源の浪費を引き起こすという問題を解決するために、本発明は５年間の使用期限を有するマスクの製造方法を提供することを目的とする。 The normal storage period of a mask is 2 to 3 years, and in order to solve the problem of causing waste of resources, it is an object of the present invention to provide a method for manufacturing a mask having an expiration date of 5 years. ..
上記目的を実現するために、本発明は下記の技術的手段を用いる。 In order to achieve the above object, the present invention uses the following technical means.

Process S1 for producing melt blown non-woven fabric and
Step S2 for producing pure water and
Step S3 to implement the dual technique of water flow confounding electret + electric electret for melt blow nonwoven fabric, and
Step S4 of manufacturing a mask from the melt-blow non-woven fabric after drying the melt-blow non-woven fabric.
A method for manufacturing a mask having an expiration date of 5 years, comprising a step S5 of vacuum packaging and obtaining a mask having an expiration date of 5 years.
前記Ｓ１において、メルトブロー不織布の生産は紡糸口金の孔径を小さくし、紡糸口金の孔密度を大きくすることにより、吐出される糸がより細かくなり、エレクトレット高流動性１５００ポリプロピレンが選ばれ、少量のエレクトレットマスターバッチが添加されている。このように製造したメルトブロー不織布は、静電気を印加しなくても、ろ過効率が９５％～９９．９％に達することができ、従来の静電気を印加しないメルトブロー不織布に比べ、効率が約１倍も高くなるので、僅かに静電気を印加すればメルトブロー不織布のろ過効率は９９％以上に達することができる。 In the production of the melt blown nonwoven fabric in S1, the pore diameter of the spinneret is reduced and the pore density of the spinneret is increased, so that the discharged yarn becomes finer, and electret high fluidity 1500 polypropylene is selected, and a small amount of electret is selected. A master batch has been added. The melt-blow non-woven fabric produced in this way can reach a filtration efficiency of 95% to 99.9% without applying static electricity, which is about 1 times higher than that of the conventional melt-blow non-woven fabric to which static electricity is not applied. Since it becomes high, the filtration efficiency of the melt blow nonwoven fabric can reach 99% or more if a slight amount of static electricity is applied.
前記Ｓ２において、水道水を水源として選択し、水源をサンドフィルタろ過及び活性炭ろ過し、ろ過された水源に逆浸透薬品及び塩酸を入れ、水源を逆浸透膜による二次ろ過し、ろ過された水源にアルカリ性工業薬品を入れ、純水の製造を完成させる。 In S2, tap water is selected as the water source, the water source is sand-filter filtered and activated charcoal filtered, back-penetration chemicals and hydrochloric acid are put into the filtered water source, the water source is secondarily filtered by a reverse osmosis membrane, and the filtered water source is used. Add alkaline industrial chemicals to the filter to complete the production of pure water.
前記Ｓ３において、高圧ポンプを介して製造された純水を扇形ノズルに輸送し、扇形ノズルがメルトブロー不織布に対してジェット水流を噴射し、純水とメルトブロー不織布とが摩擦することにより電荷が生じ、水流交絡エレクトレット＋電気エレクトレットの二重技術を完成させる。 In S3, pure water produced via a high-pressure pump is transported to a fan-shaped nozzle, the fan-shaped nozzle injects a jet water stream onto the melt-blow non-woven fabric, and the pure water and the melt-blow non-woven fabric rub against each other to generate an electric charge. Complete the dual technology of water flow entanglement electlet + electric electlet.
前記Ｓ４において、乾燥過程で熱風乾燥を用いる。 In S4, hot air drying is used in the drying process.
前記Ｓ５において、それぞれの包装袋に１粒の乾燥剤を割り当ててから密封し真空包装を行うと同時に、包装箱に１粒の乾燥剤を割り当てる。 In S5, one desiccant is assigned to each packaging bag, and then the packaging is sealed and vacuum-packed, and at the same time, one desiccant is assigned to the packaging box.
なかでも、メルトブロー不織布の生産に１６００ｍｍメルトブロー機が用いられる。１６００ｍｍメルトブロー機は全て改良されたダイを用い、紡糸口金の孔径が０．２２ｍｍであり、さらにブレーク技術が用いられている。流路は最も進んだテーパ状設計及び水素化仕上げを行った流路技術を用い、スムーズな吐糸を確保し、膨張率が低く、均一に発散しフィラメント形成し、吐糸の起毛効果を大幅に向上した。 Among them, a 1600 mm melt blow machine is used for producing a melt blow nonwoven fabric. All 1600 mm melt blow machines use improved dies, the spinneret has a hole diameter of 0.22 mm, and break technology is used. The flow path uses the most advanced tapered design and hydrogenation finish flow path technology to ensure smooth spouting, has a low expansion coefficient, uniformly diverges to form filaments, and greatly enhances the raising effect of spitting yarn. Improved to.
メルトブロー設備には、大きくし長くし厚くしたスクリュー、多層の４００メッシュの高級フィルタ、カスタム格子状スクリーン、及び恒温恒湿負圧ルーム並びに２０個の６万ボルトの静電エレクトレットが取り付けられている。 Melt blow equipment is fitted with large, long and thick screws, multi-layered 400 mesh premium filters, custom grid screens, constant temperature and humidity negative pressure chambers and 20 60,000 volt electrostatic electrets.
輸入した高メルトインデックスＰＰ原料、及び進化した第２世代マスターバッチを選ぶ。ＰＰ原料にメタロセン触媒を用い、分子量分布が狭く、微結晶が小さく、抗衝撃強度及び靭性が非常に優れている。進化した第２世代マスターバッチは電力貯蔵及び分布均一性がよく、上記組合せは、通常のＰＰ材料及びマスターバッチの親和性が悪く、灰分が高く、有機過酸化物開始剤による可塑化不足、及び過酸化物残留問題によるフィラメントが荒く形成し、硬脆化する等の問題を効果的に回避することができる。 Select imported high melt index PP raw material and evolved 2nd generation masterbatch. A metallocene catalyst is used as a PP raw material, the molecular weight distribution is narrow, the crystallites are small, and the impact strength and toughness are very excellent. The evolved 2nd generation master batch has good power storage and distribution uniformity, the above combination has poor affinity for normal PP materials and master batches, high ash content, insufficient plasticization with organic peroxide initiators, and It is possible to effectively avoid problems such as the filament being roughly formed due to the problem of residual peroxide and becoming hard and embrittled.
フィラメント形成及びラッピングが均一であり、繊維の直径が小さく、十分に冷却され、長く充電できるので、メルトブロー不織布は細かく、白く、厚く、柔らかく、滑らかであり、ろ過効率の等級が高く安定している等の特徴を有する。製品が包装された後、不織布の品質及び静電気の安定性が極めて高く、負荷試験及び劣化試験に合格でき、１８～２５℃の遮光乾燥環境で、３～５年間経っても黄変、硬化、脆化及びろ過効率の大幅な低減という問題が発生しない。
実施例２
Due to uniform filament formation and wrapping, small fiber diameter, good cooling and long charge, melt blown non-woven fabric is fine, white, thick, soft, smooth, high grade of filtration efficiency and stable. It has features such as. After the product is packaged, the quality of the non-woven fabric and the stability of static electricity are extremely high, and it can pass the load test and deterioration test. The problems of embrittlement and significant reduction in filtration efficiency do not occur.
Example 2
実験により検証した。サンプルの型式は、使い捨ての医療用無菌マスク（耳かけ型）という規格を選んだ。テスト結果は前記全ての規格の製品の加速劣化性能を表すことができる。加速劣化設備はプログラム化できる恒温恒湿テストチャンバ（ＦＣＨ－Ｉ００－０１１）である。 It was verified by experiment. For the sample model, we chose the standard of disposable medical sterile mask (ear-hook type). The test results can represent the accelerated deterioration performance of products of all the above standards. The accelerated deterioration equipment is a programmable constant temperature and humidity test chamber (FCH-I00-011).
基本原理
原材料分解反応がＡｒｒｈｅｎｉｕｓ式に適合すると仮定することに基づき、加速劣化テストを行う。Ａｒｒｈｅｎｉｕｓ式は反応速率の温度に対する依頼関係を明らかにするものであり、１０℃につき上がったり下がったりする場合、反応速度は約２倍に向上するか、半分に低減する。即ち、温度が高くなると、劣化因子が大きくなり、劣化時間が減少する。しかし、温度を向上し劣化時間を短縮することで、製品の性能に影響し生成したリスクは室温の場合と同様であるべきである。相対湿度レベルが高いか、又は低いことにより多くの材料の劣化破損が深刻になる可能性があるが、加速劣化時間の計算は湿度の増加によるものではなく、温度に基づくものである。
Basic principle An accelerated deterioration test is performed based on the assumption that the raw material decomposition reaction conforms to the Arrhenius equation. The Arrhenius equation clarifies the request relationship of the reaction rate with respect to the temperature, and when the reaction rate increases or decreases at 10 ° C., the reaction rate is increased or decreased by about 2 times or reduced by half. That is, as the temperature rises, the deterioration factor increases and the deterioration time decreases. However, by increasing the temperature and shortening the deterioration time, the risks generated by affecting the performance of the product should be the same as at room temperature. High or low relative humidity levels can exacerbate the deterioration and breakage of many materials, but the calculation of accelerated deterioration time is based on temperature, not on increase in humidity.
加速劣化条件及び時間の確定
本製品は温度が６０℃、湿度が８０％ＲＨとし、Ｑ１０＝２．０、ＴＲＴ＝２５℃とし、図１の公式に従い計算した結果、ＡＡＦ＝２．０（６０－２２）／１０＝２．０３．８＝１３．９３であり、有効期限１年間の加速劣化時間：ＡＡＴ＝３６５日間／１３．９３＝２６．２日間、即ち２６日間であり、有効期限２年間の加速劣化時間：２６日間＊２＝５２日間であり、有効期限３年間の加速劣化時間：２６日間＊３＝７８日間であり、有効期限４年間の加速劣化時間：２６日間＊４＝１０４日間であった。各サンプルを取り出し、検出結果としてＢＦＥ値が何れも９５％以上であり、全て合格した。
Determining accelerated deterioration conditions and time This product has a temperature of 60 ° C, a humidity of 80% RH, Q10 = 2.0, TRT = 25 ° C, and as a result of calculation according to the formula in Fig. 1, AAF = 2.0 (60). -22) / 10 = 2.03.8 = 13.93, with an expiration date of 1 year, accelerated deterioration time: AAT = 365 days / 13.93 = 26.2 days, that is, 26 days, with an expiration date of 2 Annual accelerated deterioration time: 26 days * 2 = 52 days,
