Description
Technical field
The present invention relates to the material heat treatment technical field, specifically about a kind of thermal treatment polyalkylene glycol (PAG) water-based quenching medium stablizer; In addition, the invention still further relates to the purposes of this stablizer.
Background technology
Along with developing rapidly of Aerospace manufacturing technology and design level, particularly performance homogeneity requirement large-scale, parts with complex structures is more and more higher to the part performance, and heat treatment technics has been proposed requirements at the higher level.The quenchant of continuing to use in thermal treatment several thousand is water and oil, adopts the mineral wet goods as quenching medium, and Environmental costs are huge.According to chemical examination, in oil smoke (mist), oil and steel surface all leave Dioxins, have extremely strong carinogenicity, Heat Treatment Workers lung cancer, nasopharyngeal carcinoma sickness rate are also higher than other occupation.In oil smoke (mist), particle enters the occupational illness increase that atmosphere causes, and hazard area is larger.In addition, contain in quenching oil than multi-metal, clean rear as in line, with polluted source.Heat treated oil-quenching tank is the guard key object of safety in production disaster hidden-trouble, water-based quenching medium is the important directions of development, the PAG water-based quenching medium is to use maximum quenchants, due to the easy to foaming corruption of organic quenchant, during salt bath heating, the subsidiary salt pair hardening liquid of part has destruction, needs to use stablizer to improve quenchant stability and work-ing life.
Summary of the invention
Technical problem to be solved by this invention is to propose a kind ofly effectively to improve quenchant stability and the thermal treatment PAG water-based quenching medium stablizer in work-ing life, and proposes the purposes of this stablizer.
A kind of thermal treatment PAG water-based quenching medium stablizer that the present invention provides for solving its technical problem is comprised of the component of following weight part: broken bubble polysiloxane solution 1-10 part, valerone 1-12 part, alkenyl succinic acid-zinc naphthenate 1-15 part, barium sulfonate 1-5 part and polyoxyethylene glycol 1-8 part.
The preparation method of the above-mentioned thermal treatment PAG of the present invention water-based quenching medium stablizer there is no special feature, only needs each component is mixed to get final product.
The contrary molten PAG of being possesses the basis that can regulate cooling characteristic.In quench cooled, PAG can not only surpass the water of cloud point precipitation around the workpiece out, but also may stick to together on workpiece surface with other precipitations PAG polymkeric substance out, the concentration of this part PAG, and we are called effective concentration to it.Hardening liquid is made heat test and is found in beaker, the hardening liquid of new preparation, and when being heated to boiling temperature, precipitation polymkeric substance out can all be floccule mass gets together, and has been with water vapour at first to float on liquid level because wrapping up in.When being heated to boiling temperature through the PAG hardening liquid of life-time service, just may some precipitation polymkeric substance out be with other polymkeric substance meet into cotton-shaped, but at the bottom of sinking to as snowflake alone glass; After salt bath quenching, mineral salt can enter in quenching solution, the contrary molten effect of PAG solution is the result of hydrogen bond action between diethyl polyethers and water molecules, and mineral salt enter the bonding force that can weaken undoubtedly this hydrogen bond, make the cloud point of corresponding solution decrease, thereby cause PAG solution to show the vapor film extension of limitation, affect quenching effect.Aforementioned stable agent of the present invention adds, and can effectively improve certain density PAG hardening liquid stability, improves the contrary molten effect of precipitation polymkeric substance out, and throw out is less; When salt bath quenching, can improve the anti-mineral salt ability of solution, reduce the loss that mineral salt causes.
Along with the wherein increase of stabiliser content, vapor film timeliness, maximum cooling rate and 300 ℃ of cooling rates all have different the variation.When the firm dip quench liquid of high-temperature probe, the gasification of separating out with the probe ambient water of polymkeric substance occurs simultaneously, originally the stablizer that was dissolved in water has small part at the probe surface crystallization, these stablizer rayings and conduction heating will produce blast to a certain extent, blast impulse has been broken the polymer capsule on probe surface, this probe surface, position is exposed in the aqueous solution, thereby has accelerated speed of cooling.In solution, stabilizer concentration is higher, and the speed of cooling increase that blast causes is also just larger.Therefore when preparation PAG hardening liquid, should strictly control the add-on of stablizer, be advisable to be no more than 2% percentage concentration, preferred add-on is the 0.1-2% of PAG aqueous solution weight.
It is take polyalkylene glycol (PAG) as main composition water-based quenching medium that thermal treatment PAG water-based quenching medium stablizer of the present invention is mainly used in, and the mass percentage concentration of polyalkylene glycol (PAG) aqueous solution is 5.0%-30%.Have suppress foam produce, anticorrosion and increase the multi-functional such as stability.Preparing the water-based quenching medium use temperature is 15-70 ℃, produces continuously the working order of energy held stationary, and the workpiece hardness of production is without impact, without corrosion pit, any surface finish, superior in quality.That this stablizer has is cheap, add after the advantages such as smokeless, odorlessness, good fluidity, salt bath quenching good stability, have the value of applying.
