Abstract
The present invention is the technical field that belongs to enamel adhesion property detection method.The present invention marks the cycloid cut with the syringe needle that is added with certain pressure on the aluminium-foil enamel face, check the dropping situations of cut and edge enamel coating thereof, determines the adhesion property of tested aluminium-foil enamel with this.The present invention can determine the adhesion property certified products of aluminium-foil enamel more accurately than the curved detection method.
Description
The present invention is the technical field that belongs to enamel adhesion property detection method.
After adherence is meant that enamel burns till, the performance of enamel and metal strong bonded.The adherence detection is the mensuration to enamel enamel coating adherence strength on the metal mold.The general indirect method that adopts is measured it.To the mensuration of aluminium-foil enamel adhesion property, as described in " development of aluminium-foil enamel " literary composition in " Chinese enamel " the 2nd phase in 1985 (the 6th volume), be to adopt bending method.That is: with 90～180 ° of angles of sample bending, judge adherence by the enamel coating dropping situations.
" paint film adhesion determination method " joint has been described with the paint film adhesion analyzer and has been measured the method for paint film to the ground bonding adhesive attraction in " first of State Standard of the People's Republic of China's coating test method ".The syringe needle that is about to analyzer is pressed in the tested paint film, makes syringe needle touch base plate and mark garden rolling curve cut on paint film, checks pull-away situation between cut, with this paint film adhesion is defined the level.
In order to measure the adhesion property of aluminium-foil enamel more accurately and reliably, invented the scratch detection method of aluminium-foil enamel adhesion property.
The scratch detection method of being invented is to adopt Coating adhesion test instrument as detecting instrument.During test, tested aluminium-foil enamel sheet is fixed on the testing table of test instrument, and the mode that adopts screw rod to screw will be pressed on the testing table around the tested aluminium-foil enamel sheet with a pressing plate, with the syringe needle pressurization of analyzer, it is dark to make syringe needle be pressed into aluminium-foil enamel surface 0.05 ± 0.01mm.Behind the starting characteristics test instrument, syringe needle can mark garden rolling curve cut on the aluminium-foil enamel surface.Dropping situations with naked eyes or lens examination cut and cut edge enamel layer; If only have enamel layer to come off at the cut place, then the adhesion property of test sample is qualified; If cut and cut edge all have enamel layer to come off, then the adhesion property of test sample is defective.
The scratch detection method of the aluminium-foil enamel adhesion property of being invented can detect the adhesion property of aluminium-foil enamel more accurately than the curved detection method.Detect with bending method, because aluminium foil has good ductility, producing in aluminium-foil enamel again in firing the process of aluminium-foil enamel has internal stress, though the bad tested product of adhesion property, though still can not fall porcelain through curved detection, thereby can be mistaken as certified products.The etch of atmospheric conditions such as acid, alkali is placed or met to such certified products through certain hour, can occur that enamel coating is quick-fried to fall because the enamel coating adhesion property is defective.Through the detected certified products of scratch detection method, the quick-fried phenomenon that falls of above-mentioned enamel coating can not appear because adhesion property is defective.
The instrument that the scratch detection method of best aluminium-foil enamel adhesion property adopts is the electronic Coating adhesion test instrument of QFD type.To test instrument syringe needle institute plus-pressure, look aluminium foil and porcelain thickness and determine 50 the gram to 300 the gram between.Adopt the pressing plate of having vacant position in the middle of that sample is pressed on the testing table, make the test instrument syringe needle mark garden rolling curve cut on the sample in the room.
Claims (1)
1, aluminium-foil enamel adhesion property detection method, feature of the present invention are to mark garden rolling curve cut with syringe needle on the aluminium-foil enamel face, determine according to the porcelain situation of taking off at cut and cut edge whether the adhesion property of sample is qualified.
