中文摘要 | 本研究以高濃度散漿並配合各種處理條件來進行試驗,嘗試在高濃度散漿過程中 以較溫和的處理條件來散漿, 藉而達到減少用水量、葯品用量、動力消耗及提高脫墨漿品質等。實驗 結果綜合如下: 1.高濃度散漿在處理進口雜誌紙、影印紙、混合癈紙等三種漿料後,留存於紙漿中之油墨粒 子皆比傳統水力散漿來得小。 2.在不添加藥品的高濃度散漿後,白度、紙力皆會隨著散漿時間、濃度的增加而提高。 3.雜誌紙在高濃度散漿後白度皆不高,可能是卡巴值過高所致,若經迥溧白後白度可再提高 。 4.在高濃度添加鹼和脫墨葯劑散漿後,影印紙最高白度可達83.5%GE;混合紙可達到69.3GE 。 5.高濃度散漿可將影印紙的熱塑性樹脂油墨分散,其效果比傳統水力散漿好許多,若配合浮 選脫墨法後,其可目視之油墨粒子大多可移除,白度更可達到83.9%GE。 6.高濃度散漿配合聯合脫墨法對混合癈紙處理後之白度亦可超過70%GE。 |
英文摘要 | This strdy was designed to reduce awter,chemicals and power consumption in waste paper recovery,and the effects of high-consistency disintegration on qualities of recycled papers were also studied.The experimental results were summarized as follows: 1.High-consistency disintegration could reduce the ink particle size to a grea- ter extent in compare to that of the conventional deinking process for 3 var- ieties of pulps. 2.Without chemical addition,as dispersion time and pulp consistency increasing, the brightness and the strength of recycled pulp increased after the high- consistency disintegration stage. 3.The lower brightness of dispersed old magazine paper(OMP)revealed that high residual lignin(Kappa number)might be present in OMP. 4.83.5%brightness of dispersed recycled xerographic paper and 69.3% brightness of mixed papers can be achieved by adding alkali in hihg-consistency recycled wastepaper after deinking treatment. 5.Well-dispersed thermoplastic resins-containing xero graphic paper can be attained by high-consistency dispersion in contrast to conventional hydraupulping process. 6.In general, it is desirable to deink the mixed wastepaper stock under high- consistency.Dispersion with affilating washing/flotation deinking system may attain a brightness of deinked pulp over 70%. |
