摘要


橡膠木纖維型態,化學組成與省產闊葉樹相近。以硫酸法製漿,硫化度25%,用藥量15%、17%,收率分別為46.5%與47.2%,高錳酸鉀值為16左右,強度佳可做各種紙張,蘇打法、中性亞硫酸鈉法收率較高,可為芯紙紙張及紙板之用。

Fiber dimensions and chemical composition of rubber wood (Hevea brasilensis) were similiar to the average local hardwoods. Three pulping processes were used in this experiment. Satisfactory sulfate pulpw as prepared by using asulgidity of 25% and total alkali of 15% and 17% which gave yield ranging from 46.5 to 46.2% and permanaganate number of 16.42 and 16.14, respectively. Strength of the sulfate pulp indicates that the pulp is suitable for making a wide range of paper grades High yield Soda and Neutral Sulfite Semichemical NSS8 that the pulps were also prepared Test results innicate overall properties of these pulps are suitable for the production of corrugating medium and other paper and paperboard products
