Coating technology: how to determine the dilution stability of emulsion

Core tip: in the production of paint, for some thick emulsion, we often use solvents and surfactants However, in the process of emulsion debugging, this phenomenon is noticed In the emulsion, a certain amount of water or solvent is first diluted to mix up The emulsion has good mobility and low viscosity at the same time, but when placed in a period of time, After the night, we will find that the flow performance of the emulsion is getting worse and the product is also sticky There is no standard method for the determination of dilution stability of emulsion The usual methods are as follows: Test with scale in 10ml Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Home of coatings: In the production of coatings, for some thick emulsion, we often use solvents and surfactants However, in the process of emulsion debugging, this phenomenon is noticed In the emulsion, a certain amount of water or solvent is added to dilute and mix up The emulsion has good mobility and low viscosity, but when placed for a period of time or after overnight, We will find that the flow performance of the emulsion is poor and the product is sticky There is no standard method for the determination of the dilution stability of emulsion The usual methods are as follows: in the 10ml test tube with calibration, the 2ml emulsion is added with the dropper, then the 8ml ion free water is added with the dropper After fully shaking, place it on the test tube rack, and observe whether there is stratification, water separation and precipitation after 24h and 48h respectively If there is no such phenomenon, it means passing It can also be weighed in a proper container according to the above proportion, and placed in a test tube for observation after being stirred evenly Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
