中文摘要 | 本試驗中製備了一種以AKD(Alkyl Ketene Dimer)為原料之固態中性上 膠劑,其特性為便利儲存、運輸,而且不需要使用乳化機即可於溫水中乳化分散。 試驗中亦對一些影響上膠的因素加以探討。漿料之pH值接近7.0時,紙張之上 膠度良好且不化水。紙張上膠度主要受上膠劑使用量的影響,而紙張化水性受澱 粉之影響較大,添加澱粉對於增加填料保留也卓具效果,此外固態中性上膠劑之 熟成速度可使用陽離子性之熟成促進劑來控制。將固態中性上膠劑施用於手工紙 時,僅使用少量的上膠劑即可使紙張符合繪畫上的要求,所製成的中性上膠手工 特別耐久藏。 |
英文摘要 | A solid neutral sizing agent, based on alkyl ketene dimer was prepared. It can readily dispersed in warm water without the aid of a homogenizer. As a solid sizing agent, it is more convienient in storage and transportation than the commonly used AKD emulsions. The efficiency of solid neutral sizing agent is affected by pH of the stock, rate of additon, starch addition and use of curing accelerator. The test sheets were well-sized and show no feathering when stock pH was in the ranges from 6.5 to 7.5. In general, degree of sizing depends on the addition rate of sizing agent, while ink feathering property of sheet is determined by the amount of starch additons. Starch addition also has positive effects on the retention of calcium carbonate fillers. A cationic sizing accelerator is often used as well to control the curing rate of sizing agent. Handmade papersheets for Chinese painting purpose require durability and permanence. Treatment with a solid neutral sizing agent can meet the requirements satisfactorily. |
