Abstract
Description
Technical field
The present invention relates to a kind of silver fiber detection means, more particularly to a kind of resistance to scraped finish evaluation device of silver fiber.
Background technology
With the horizontal continuous improvement of the modern life, requirement of the people to quality of life is also constantly improving, clothing, food, Firmly, row clothing is first, fiber has had silver that is varied, such as being applied on nylon fiber surface as the clothing that people wear usually The obtained silver fiber of layer, the anti-electromagnetic shielding fabric made using silver fiber is excellent because of its shielding property, extensive Be used for radiation-proof clothes for gravida, it is well known that the closure that the principle of electromagnetic shield-ing of exposure suit is formed mainly by silver plated fiber is returned Road, the size of conductance will directly affect the quality of capability of electromagnetic shielding, and the thickness of the silver coating on nylon fiber surface is to determine Determine the key of silver plated fiber resistivity size, silver fiber is hooked what needle-bar was knitted repeatedly by traditional knitting machine using crochet hook Process inevitably will cause scratch to the silver layer on silver plated fiber surface, and this inevitably will have influence on electromagnetic shielding fabric Shielding property, that is to say, that the resistance value of the radiation-proof fabric of finished product will be bigger than normal, and through varying number needle-bar and not collinear The radiation-proof fabric that the number of turns measures, because the abrasion number difference of silver fiber and crochet hook does not cause degree that its resistance value declines also not Together, final finished radiation-proof fabric will be less than the effectiveness of radiation-proof fabric in theory, and the initial stage of surface silver layer grinds Damage also leads to the speed that dress, washing of the people in the later stage accelerate the failure, so as to cause the service life of radiation-proof fabric Decline.So the stress and fatigue detecting of fiber are the important steps for holding quality of textile products, it is directly related to fiber quality Deciding grade and level and terminal applies, such as clothes, household textiles, automotive upholstery multiple use.Any fiber will be through too strong Continually changing stress repetition effect is spent, therefore, the fatigue proof test of fiber is particularly important.
It is generally believed that influence silver plated fiber fatigue performance factor mainly have it is following these:
1. the toughness of fiber in itself.Research finds that the toughness of fibrous matrix in itself is stronger, and the life-span of fiber is also longer, one As generally acknowledge nylon fiber toughness it is stronger.
2. the fastness that silver coating is combined with matrix.
3. the fatigue performance of silver coating in itself.
For silver fiber, the decline of its shielding properties is mainly shown as silver coating destruction in itself and silver coating and fiber The stripping of matrix.
Method of testing on coat adhesive force has many.Such as U.S. PASS method of testing standard ASTM D3359-1997
Provide a kind of knife edge method of testing.It is on test sample surface with sharp cutter (knife edge angle is 15 °~30 °) 10 × 10 1mm × 1mm small grids are drawn, each line should deep and paint bottom;With hairbrush by the fragment brush of test zone Totally;Tested small grid is firmly clung with 350~400g/cm2 of adhesion adhesive tape (3M600 gummed papers are equivalent), is used in combination Erasing rubber firmly wipes adhesive tape, to increase the contact area of adhesive tape and tested region and dynamics;Adhesive tape one end is held, is being hung down Nogata shuts down rapidly gummed paper to (90 °), and same position carries out 2 same tests, and its result judgement method is:It is required that adhesive force >= To be qualified during 4B.Wherein 5B is that scribing edge is smooth, at the edge of line and intersection without peeling paint;4B is to rule Intersection have the peeling paint of small pieces, and the gross area that comes off is less than 5%;3B is small to have at the edge of line and intersection The peeling paint of piece, and the gross area is come off between 5%~15%;2B is to have sheet of oil at the edge of line and intersection Paint comes off, and comes off the gross area between 15%~35%;1B is de- to there is sheet of paint at the edge of line and intersection Fall, and come off the gross area between 35%~65%;0B is to have sheet of peeling paint at the edge of line and intersection, and The gross area that comes off is more than 65%.The diameter of silver fiber only has 10~20 μm, it is clear that is not suitable for this method.
U.S.'s ASTM B571-97 standards give the adhesive force of metal cladding on 11 kinds of various base materials of qualitative evaluation Method, there are bend test method, polishing experiment, towing trial, chisel experiment, file test, saw experiment, quenching test, impact examination Test, disbonded test, push experiment, frame experiment.Wherein:
1st, bend test.It is that sample center is placed on an axle, outwardly, firmly bending tries cover layer face downwards on both sides Sample, until both sides are parallel.The diameter of axle should be 4 times of sample thickness.Check that crooked position is with low power magnifying glass (such as 4 times) No to have coating peeling, this is the performance of poor adhesive force.If coating ruptures or foaming, attempted to see energy with sharp blade It is no to separate coating from base material.For hard and brittle coating, crooked position would generally be cracked.These crackles It may may also may not extend to base material.No matter which kind of situation, the cracked poor adhesive force for being not offered as sample, unless with Sharp instrument can be by overburden stripping.Then with the angle of 180 degree, alternating bending sample, until metal fracture.In low power The tilting and peeling of this region overlay layer are observed under magnifying glass (such as 10 times).Seen to separate from base material with sharp blade and covered Cap rock, if it is possible to separate, then illustrate that the adhesive force of this coating is poor.
2nd, polishing experiment.It is the instrument on the cover layer in 5cm length with one end for smooth hemispherical (a diameter of 6mm) Polish about 15s.Dynamics during polishing should remain the sample that can polish every time, but be unlikely to make sample surfaces generation recessed Trace.See whether foaming, separation and peeling phenomenon occur.Generally, the result obtained when coating is thicker can less make us full Meaning.
3rd, chisel is tested.The coating for the sample surfaces to be tested is pierced through with sharp cold chisel.Chisel can It to be pierced into from coating rear portion, can also first be cut with saw, then be pierced into from the faying face of the coating and base material exposed.Can Chisel is replaced with knife.During with knife, it can be hammered into shape or other instruments rap, can also do not had to hammer.If in this way Can removes coating, then its adhesive force is poor.When coating is softer or thin, this method does not apply to.
4th, towing trial.On common punch press, from adjustable punch die, the sample stretching that diameter is about 60mm is turned into One a diameter of 38mm, deep the 18mm calotte with bead.Male die is persistently penetrated, until calotte is broken.Can be direct The adhesive force situation of coating is observed, can also further be commented by the technology separated from base material that the 5th part provides Valency.Peeling if there is coating separates with base material, then the adhesive force of coating is poor.What this method obtained Result of the test is not only related to the pliability of coating, also relates to the pliability of base material.
5th, file test.A piece of test specimen under saw, checks whether coating and base material separate.In saw kerf with coarse file Filed from base material direction to coating direction, angle and the cover surface of file are in 45 degree of angles.If coating peels off or from base material Separation, then it is unqualified to be considered as adhesive force.
6th, saw experiment.With Carborundum wheel from base material to coating direction fly-cutting sample.It can also be replaced with bow saw Carborundum wheel, but equally to be sawed from base material to coating direction.Peel off or separate if there is coating, so that it may be considered as adhesive force It is unqualified.
7th, quenching test.Heating sample for a period of time, reaches certain temperature in stove.Furnace temperature is kept in selected temperature In the range of ± 10 DEG C of degree.If coating or base material are oxidizable, should be heated in inert gas or appropriate liquid. Then at room temperature by sample be put into water or other appropriate liquid in quenched.If there is peeling off or separating, then try The adhesive force of sample is unqualified.It in coating micropore and can be wrapped up in micro- hole of base material and deposit some electroplating solutions, these electroplating solution meetings Heating and bubble is formed in quenching process.If bubble around coating will not separate from base material, these steep presence not by It is considered as the bad evidence of adhesive force.
8th, impact test.Sample is placed on an appropriate supporter, made with hammer or other Apparatus for Impacting at low-temp hammering sample It is deformed.A diameter of 5mm of impact head or special provision, added with load during impact.Gravure or periphery coating are if there is de- Fall or bubble, then the adhesive force of sample is unqualified.
9th, disbonded test.By a wide 20mm, thickness about 1.5mm steel bar or brass rod are welded or glued with appropriate adhesive Knot is at a certain smooth position in sample to be tested surface.Also applicable one-faced tapes replace.Adhesive can be heated.Peel off When degree angle, speed, the thickness and width of institute's metal bar (adhesive tape) etc. it is fixed.If the interface of coating and base material goes out incumbent What is abnormal, it is believed that adhesive force is unqualified.
10th, experiment is pushed.From base material to coating direction, an a diameter of 0.75cm obstructed hole is bored, until drill bit Stop after the drill-through general 1.5mm of coating and substrate interface.Sample is placed on a diameter of 2.5mm annulus, with one A diameter of 0.6cm card punch, it is pressed downward with one end that stable pressure is obstructed in hole, the east until being biased out a button-like West.If the coating around coating or hole on the thing of button-like occurs coming off or separated, the attached of sample can be considered Put forth effort unqualified.
11st, frame is tested.The parallel lines of 3 or more are marked in specimen surface or draw a gridiron pattern with steel knife. The knife of frame should be sharp, and point of a knife is 30 degree, and the distance between drawn parallel lines are about 10 times of overburden cover, Minimum is not less than 0.4mm.In setting-out, it is ensured that every line is all drawn to base material.If a certain piece on gridiron pattern is from base material Come off, then it is assumed that the adhesive force of the sample is unqualified.If it is qualified that sample adhesive force in above-mentioned steps is shown as, finger is used Pressure sensitive adhesive tape (adhesion strength of adhesive tape is at least 45g/mm) is pressed against on clean gridiron pattern.Before rubberized fabric, it should be ensured that Particle and chip are removed clean caused by all strokes of lattice on gridiron pattern.After adhesive plaster posts, the free end of adhesive tape is caught, quickly (not being to wrench) pulls open adhesive tape.It is in 180 degree angle that free end, which should try one's best with specimen surface, when pulling open.If it is stained with adhesive tape from chessboard The coating to be come off in lattice, then the adhesive force of coating is unqualified.The coating being connected with gridiron pattern is not considered.
The standard explicitly points out that " explanation to the qualitative detection test method of metal cladding adhesive force is often disputable 's." and it is further noted that the experiment such as chisel experiment, file test, saw experiment, pushing experiment and frame is not suitable for coating Softer or thin sample, while be also believed that the final service condition and mode of coating piece determine can best its work(of representative The test method of requirement can be gone up.For example, for the coating piece then to assemble, crooked test or towing trial are suitable;It is right Quenching test is then appropriate in weld or be exposed to the sample under high temperature.If a part need after spray coating baking or Heat treatment, then need to carry out the test of adhesive force." there was only 10~20 μm due to the diameter of silver fiber, and it is very soft, silver coating is only There are several microns, what silver fiber was subject in its weaving process is the effect such as pulling repeatedly, bending, mantle friction, these works Comprehensive function result causes the destruction or stripping of silver coating, shows as the rise of resistance value, so as to cause electromagnetic shielding to be imitated The decline of energy.Therefore the fatigue performance of evaluation silver fiber is not suitable for any one of these methods.
Above-mentioned method and apparatus is merely capable of measuring the number of fibrous fracture failure, but can not simulate fiber and exist With the realistic tribological mode of crochet hook during woven, and can not be measured by way of fracture for silver plated fiber Resistance change of the silver layer when being scraped with crochet hook each time, and the silver-plated amount that the problem controls silver layer in advance can not be directed to, come Obtain the electromagnetic shielding Expected Results of final finished fabric.
