摘要

由於造紙用水循環系統趨向於密閉化，因而產生造紙機操作上的問題，其中以微生物菌泥最為嚴重，可導致紙張破孔、菌斑及抄造斷紙等現象。為解決這些問題，增加造紙機操作性和增加造紙的品質及產能，所以必需於造紙濕端系統中添加殺菌劑。

本實驗是針對一般常使用的殺菌劑成份進行混合之研究，以尋求更恰當的殺菌劑供業界參考，共以QUAT、DGH、DBNPA、GLUT、MBTBC、Bronopol、Sulfone、ISO、Dithiol九種依等比例進行混合，最後再挑選出效果最佳的混合殺菌劑以不同比例混合，以得到最佳的殺菌效果。

實驗結果中發現，以QUAT 10% 與 Sulfone 10%、QUAT 12% 與 Sulfone 8%、QUAT 5% 與 Sulfone 15%混合之試劑及以Dithiol 5% 與 MBTBC 15% 混合之試劑效果最佳，總菌數殺菌率可達95%以上，酵母菌/霉菌殺菌率可達70%以上。但如果需求朝向於防腐的功能，則可以選擇以MBTBC 10%與Sulfone %混合之組合試劑，酵母菌/霉菌殺菌率也可達70%以上。

Abstract

As paper mills are use more recycled materials and close up white water systems, water quality tends to deteriorate and slimes resulting from attached microbial growth on paper machine parts becomes more serious. Microbial slimes obtain nutrients from water and form gelatinous films that may also form aggregates with other solids materials and become sticky deposits. Detached slimes would then cause spots and holes on the paper products and could lead to loss of paper strength and more brokes. The growth conditions needed for slime growth are discussed and various preventive measures delineated. The kinds and proper applications of biocides are request in the papermaking system.

The study is research 8 species biocide to do mixing. After mixing we addition it in the sample and measure the total bacteria count and yeast/mold count. It will find the mixture that is a good killing rate for papermaking microorganism.

The best results of this study are QUAT10% & Sulfone 10% mixture, QUAT 5% & Sulfone 15% mixture, QUAT12% & Sulfone 8% mixture and Dithiol 5% & MBTBC 15% mixture. We can get total bacteria count killing rate over 95% and yeast/mold killing rate over 70%. If we need feed biocide for additive chemical to prevent mold. We can recommend to use MBTBC 10% and Sulfone 10% mixture. It can get yeast/mold killing rate over 70%, too.
