The unavailability of biodegradable preservatives is one of the major setbacks in the construction industry. With this in mind, our study focused on the analysis and comparison of two hydrophobic liquids, one vegetable oil-based (VOA) and the other mineral oil-based (MOA), and subsequently applying the same on three types of wood. The comparison of the vegetable oil-based (VOA) and mineral oil-based (MOA) revealed that VOA was characterized by an 83.4% susceptibility to aerobic biodegradation, while MOA was considerably more resistant (47.80%). Based on the conducted contact angle measurements, it was observed that the wettability of pine and oak wood decreased after the application of both VOA (for pine-twice; for oak-by 38%) and MOA (for pine-more than two times; for oak-by 49%), while in the case of aspen, the same was increased (after the application of VOA-by 20%; after the application of MOA-by 2%). The observed depth of penetration into the structure of the impregnated wood was lower for the VOA impregnant as compared to the MOA impregnant. This result persisted in all types of wood used in the experiment. Observations of the process of water absorption during soaking revealed that VOA was more beneficial in terms of lowering water absorption into the material, regardless of wood type. The overall results were better for VOA, which lowered the mass of soaked wood by between 19.73 and 66.90%.
可生物降解防腐剂的缺乏是建筑业的主要挫折之一。考虑到这一点，我们的研究集中于分析和比较两种疏水性液体，一种是植物油基（VOA），另一种是矿物油基（MOA），随后将它们应用于三种木材。植物油基（VOA）和矿物油基（MOA）的比较表明，VOA的需氧生物降解敏感性为83.4%，而MOA的抗性则强得多（47.80%）。基于进行的接触角测量，观察到在应用VOA（松树-两次；橡树-38%）和MOA（松树-超过两次；橡树-49%）后，松木和橡木的润湿性下降，而对于白杨木，润湿性则增加（应用VOA后-20%；应用MOA后-2%）。与MOA浸渍剂相比，VOA浸渍剂对浸渍木材结构的渗透深度较低。这一结果在实验中使用的所有木材类型中都存在。浸泡过程中吸水率的观察表明，无论木材类型如何，VOA在降低材料吸水率方面更有益。VOA的总体结果更好，它使浸泡木材的质量降低了19.73%至66.90%。
