Description
Technical field
The present invention relates to a kind of bunker oil emulsifier composition and uses thereof.
Background technology
The Seal Design of screw shaft of ship is a challenging problem always, the defect designed by stern shaft seal and the stern tube shaft leakage of oil that brings or a water inlet stubborn problem especially.Boats and ships in reality operation due to environmental factors more complicated, particularly adverse weather condition under water screw unavoidably produce larger vibration or average reason when running and cause tail sealing device to lose efficacy thus cause entering of the leakage of oil or water.Stern tube shaft water inlet happens occasionally, and is a kind of common fault, if oil product is containing water excess, will reduces and even lose lubricity, thus causes the wearing and tearing of parts and the corrosion aggravation of equipment.The metal particle that moisture and wearing and tearing produce accelerates again the deterioration by oxidation of oil product, makes bunker oil shortening in work-ing life.The cruise duration of boats and ships is longer, once there is stern tube shaft water inlet, except docking, crewman often feels simply helpless.This is the shortcoming that lubrication trailing axle and tube is fatal, causes heavy economic losses to maritime industry.
Domesticly there is no special stern axle oil, generally carry out lubrication and cooling stern tube shaft with ship lubricant oil.Ship lubricant oil (engine with outside guide crankcase oils) is not mainly used to contacts fuel gas lubricate bearing relevant in crankcase and crosshead slipper etc., and meanwhile, system oil is also the heat-eliminating medium of oil-cooled engine piston.Because system oil is not specially stern tube shaft and developing, therefore once contact with water emulsification can't occur, the very easily corrosion stern tube shaft associated components when seawater enters stern tube shaft, brings danger safely to navigating.And stern tube shaft oil once leak just can swim in waterborne to environment, if stern tube shaft oil there is emulsifying capacity once leak will with water generation emulsification, like that can be diluted by seawater rapidly, reduce the pressure to environment.
Abroad, Shell Co. Ltd have developed the lubricating oil being specifically designed to stern tube shaft, and the said firm claims that the maximum feature of this lubricating oil is the use properties can not affecting lubricating oil when the entering and be no more than 20% of water.Castrol company have also been developed this series products, but is not described the amount of energy Solubilization of Water, points out in its technical indicator, 12mL water can be separated out at 23 DEG C, this 12mL is under what conditions, and moisturely how much just can separate out, and Castrol company does not carry out any explanation.
Seldom, more similar emulsified bitumen, the achievement in research of diesel oil emulsification are a lot of in the domestic work carried out for emulsion type lubricant peculiar to vessel.Such as document CN201010227477.5 discloses a kind of emulsified bitumen and preparation method thereof, adopts the formula of positively charged ion and nonionogenic tenside composite emulsifier and assistant for emulsifying agent.Diesel oil emulsification addictive disclosed in document CN1803993A, using sodium hydroxide as emulsion stabilizer.Document CN1766045A discloses a kind of preparation method of diesel oil emulsification, utilizes microwave, ultrasonic wave and magnetic rotation to penetrate and labyrinth magnetic intensifies to process diesel oil emulsification.
