The quality of garden tool oil is directly related to whether the garden tool can operate normally. If the quality of oil used in garden tools is not good enough, it will not only make the garden tools prone to failure, but also cause great damage to the garden tools themselves. Therefore, you must pay attention when choosing oil for garden tools.
1. Look at the appearance.
Different types of oils have different color appearances. . Carefully observe the appearance and color of the oil. The light color is mostly light distillate and highly refined oil, and the dark color is mostly residual oil residue, low-refined oil, or heavy distillate oil. .
2. Smell the smell.
The smell of oil is generally divided into gasoline, kerosene, diesel, alcohol, aromatic, sour and so on. Oils with additives have a certain sour taste; oils with alcohol content have an alcoholic taste; light solvent oils have an aromatic taste.
3. Feel the soft and hard conditions and smoothness of the oil.
The refined oily hand mold has a strong smoothness, while the poorly refined oily hand mold has a poor smoothness. Grease and the degree of hardness can be roughly divided into different grades, the smaller the number is softer, the larger the number is harder.
4. After shaking, observe the thickness of the oil.
Shake the oil in a colorless glass bottle, and observe the phenomenon of the oil film hanging on the bottle and the occurrence and disappearance of bubbles. You can basically distinguish the different grades of the oil. Oil with low viscosity produces more bubbles, rises quickly, disappears quickly, and has fewer bottles; oil with high viscosity produces less bubbles, rises slowly, and disappears slowly, but there are more bottles of oil.
