早期研究发现在未磨、未漂的原浆中加入1%的臭氧,可以在游离度基本不变的情况下,使抗张强度和耐破度提高50%。随后的研究表明,在臭氧用量为1%时,回用包装纸浆的抗张强度约提高20%。在这
Earlier studies have found that adding 1% ozone to unpurified and unbleached virgin pulp results in a 50% increase in tensile and burst resistance with essentially the same freeness. Subsequent studies showed that the tensile strength of recycled paper pulp was increased by about 20% at 1% ozone. At this
