ABSTRACT

Beef tallow is a by-product of rendering of fats from meat production. While tallow can be used for a variety of applications including biodiesel production, it might also be useful for enhancing the water resistance of wood to improve durability. The effects of differing retentions of tallow on wood performance were evaluated in scots pine, beech and poplar. Tallow slowed but did not completely limit water uptake nor did it completely inhibit swelling. Fourier transform infrared spectroscopic analysis indicated that tallow did not appreciably alter the wood chemistry and TGA analysis suggested that it had only minor thermal effects. Fungal exposures suggested that tallow treatment improved decay resistance slightly but would not function as a stand-alone wood protectant. The results suggest that tallow might be a useful additive for bulking the wood to enhance water repellency of an existing preservative.

摘要

牛脂是肉类生产中脂肪提炼的副产品。虽然牛脂可用于包括生物柴油生产在内的各种应用，但它也可能有助于增强木材的防水性以提高耐用性。在苏格兰松、山毛榉和杨树中评估了不同动物脂保留量对木材性能的影响。牛脂减慢但没有完全限制吸水量也没有完全抑制肿胀。傅里叶变换红外光谱分析表明牛脂不会明显改变木材的化学性质，TGA 分析表明它只有很小的热效应。真菌暴露表明牛脂处理略微提高了抗腐性，但不能作为独立的木材保护剂。
