The quality of the garden tool oil is directly related […]
The quality of the garden tool oil is directly related to whether the garden tool can operate normally. If the quality of the oil used in the garden tools is not high 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 color of the oil. The light color is mostly light distillate and deeply refined oil. The dark color is mostly residual oil residue, oil with low refining degree, or heavy 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 condition and smoothness of the oil.
The refined oil hand mold has strong smoothness, and the poorly refined oil has poor smoothness. Grease and softness can be roughly divided into different grades. The smaller ones are softer and the larger ones are harder.
4. Observe the thickness of the oil after shaking.
Shake the oil product in a colorless glass bottle, and observe the oil film hanging condition and the occurrence and disappearance of bubbles, etc., you can basically distinguish the different brands of oil products. Oils with low viscosity have many bubbles, rising quickly, disappearing quickly, and few bottles hanging; oils with high viscosity have less bubbles, rising slowly, and disappearing slowly, but there are more oil hanging bottles.
