由于桐油在温度过低或过高,以及光照条件下都易氧化的特性,我们总结多年桐油储藏工作,其基本经验是: 1.储藏环境。储藏桐油的场地最好冬暖夏凉、地坪干燥,要能通风又能密闭的仓房或油棚内。在冬季要设法保持油温在5℃以上,使桐油处于液体状态。但在室内生火加温时,必须注重防火。 2.严格掌握入库桐油质量。严防酸价、水分、杂质超标的桐油以及刚落榨的热油入库。新榨的桐油应沉淀3—5天,取其清油入库。近年来,桐油掺伪的现象时有发生,这就造成桐油的安全储存极不利因素。因此,在桐油收购和入库时,更应注意把好质量关。
As tung oil in the temperature is too low or too high, as well as light conditions are easy to oxidize the characteristics, we summarize the tung oil storage for many years, the basic experience is: 1. Storage environment. The best place to store tung oil is warm in winter and cool in summer. The floor is dry, and it is necessary to ventilate and seal the warehouse or oil shed. In winter to try to keep the oil temperature above 5 ℃, so that the tung oil in a liquid state. However, when indoor heating and warming, we must focus on fire prevention. 2. Strictly grasp the quality of tung oil storage. Prevent acid value, moisture, impurities exceeded the tung oil and freshly squeezed hot oil storage. The new squeezed tung oil should precipitate 3-5 days, whichever is the clear oil storage. In recent years, the phenomenon of tung oil adulteration has occurred from time to time, which resulted in the safe storage of tung oil extremely unfavorable factors. Therefore, the tung oil acquisition and storage, should pay more attention to good quality.
