中文摘要 | 本文研究聚乙烯醇與化工澱粉漿料之相容性,針對這兩種漿料之混合比例、聚乙烯醇之鹼化度、溫度等參數探討漿液之相分離現象,實驗結果顯示,聚乙烯醇含量在30~60%之間,較容易發生相分離;在鹼化度方面,以完全鹼化型的聚乙烯醇與化工澱粉的相容性較佳;在溫度方面,隨著溫度的升高,漿液越容易產生相分離。 |
英文摘要 | The miscibility of polyvinyl alcohol and modified starch is described in this paper. It depends on mix ratio, the degree of hydrolysis, temperature, and so on. The phase seperation was found at different conditions. It's easy to seperate when the PYA ratio is 30-60%. The miscibility increases as the hydrolysis degree of PYA increases. The phase seperation is easier to occur as temperature is higher. |
