油污清洗剂的哪些分类
Which classification of oil cleaning agents
溶剂型的，也要考虑到溶剂本身的气味与挥发速度，气味太大会让清洗工人接受不了，挥发速度太慢则降低清洗效率。一般而言挥发快则气味就大，如果要求挥发快、气味小且环保则成本就会大大增加。
Solvent type, also to take into account the odor and volatilization of the solvent itself, the odor is too general for the cleaning workers can not accept, the rate of volatilization is too slow to reduce the efficiency of cleaning. Generally speaking, when volatilization is fast, the smell is large. If the requirement is fast, the smell is small and environmental protection, the cost will increase greatly.
水基型或混合型的，则有碱性、中性与酸性之分。通常在同等条件下，碱性、中性与酸性油污清洗剂的除油能力依次降低，酸性的，一般兼有除锈功能，而中性的，则对人体更温和。水基型的，一般气味会小或没有气味，且有需要加热和不需要加热之分，需要加热的水基清洗剂，加热会大大提高除油能力。
Water based or mixed type is alkaline, neutral and acidic. Under the same condition, the degreasing ability of alkaline, neutral and acid oil cleaning agents is reduced in turn, acid and generally has the function of removing rust, while neutral, it is more mild to the human body. Water based type, the general smell will be small or no smell, and there is a need to heat and do not need heating, the need to heat the water base cleaning agent, heating will greatly improve the oil removal capacity.
混合型的兑水前是溶剂，兑水后会乳化成乳化液，不需要加热，略微有些气味。从成本的角度看，一般水基型都能兑水10～20倍，所以使用起来成本会更低一些。但比起除油能力还是溶剂型的强一些，快一些。
The mixed type is solvent before mixing water, and it will be emulsified after mixing with water, without heating and slightly smelling. From a cost point of view, the general water-based type can be 10~20 times the water, so the cost of using it will be lower. But it's faster than the ability to remove oil or solvent.
