Abstract
The invention relates to a method for testing rust-proof and corrosion-resistant properties of metal parts used on garment products. The method comprises the following steps: selecting the two identical metallic components, and using one as a sample to be tested, and the other as a control sample; placing the sample to be tested in the pretreatment environment at the temperature of 21 DEG C+/-2 DEG C and with the relative humidity of 65% plus or minus 2%, and allowing the sample to stand for at least 4 hours; preparing a NaCl solution with the concentration of 1%, taking a piece of pure cotton white cloth; completely soaking the white cloth in the NaCl solution; after the completion of the soak, taking out the pure cotton white cloth; lightly extruding out excess solution on the pure cotton white cloth; using the soaked the pure cotton white cloth to wrap well the sample to be tested, and placing the sample in an oven at the temperature of 38 DEG C+/-1 DEG C; and after taking out the sample, comparing the sample to be tested and the control sample and recording and assessing the differences of the sample to be tested, wherein the greater the difference, the rust-proof and corrosion-resistant properties are worse. The method has the benefits that the rust-proof and corrosion-resistant properties of the metal parts used on the garment products can be tested and accessed; the method is simple and convenient; and test results are intuitive and clear.
Description
[technical field]
The present invention relates to rust resistance and corrosion resistance property testing technical field, specifically a kind of metal parts rust resistance and corrosion resistance method of testing to using on the dress-goods.
[background technology]
Metal-ware is as the auxiliary material of dress-goods, be mainly used in metal zip fastener, metal snap fastener and other metal tightness parts etc., because such metal-ware has good durability, therefore by a large amount of being applied in the dress-goods such as adult, children, baby.Yet, based on the intrinsic self-characteristic of metal-ware, may be because of the impact of external environment in the process of using, tend to occur metal-ware is corroded or metal-ware on produce the situation such as rusty stain, and the rusty stain that is corroded and produces etc. can cause the contamination to the clothing product, and is difficult to remove.Therefore, at present in the urgent need to a method of testing antirust, anti-corrosive performance of the metal parts that uses on the dress-goods is tested and estimated.If such method of testing can be provided, will have very important significance.
[summary of the invention]
Purpose of the present invention is exactly to solve above-mentioned deficiency, and a kind of metal rust preventing anti corrosion test method is provided, and can test and estimate the antirust, anti-corrosive performance of the metal parts that uses on the dress-goods, and also simple, convenient.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of metal rust preventing anti corrosion test method may further comprise the steps:
1) choose two identical metal parts, one of them is as testing sample, and another is sample in contrast;
2) testing sample being placed on temperature is 21 ± 2 ℃, and relative humidity is in 65% ± 2% the pre-service environment, to leave standstill at least 4 hours;
3) configuration concentration is 1% NaCl solution;
4) get a textile calico, textile calico is soaked in the NaCl solution fully;
5) after immersion is finished, textile calico is taken out, gently extrude solution unnecessary on the textile calico;
6) with the textile calico that soaks testing sample is wrapped, and to put into temperature be 38 ± 1 ℃ baking oven;
7) from baking oven, after the taking-up, compare testing sample and control sample, the difference of record and evaluation testing sample, difference is larger, and then rust resistance and corrosion resistance is poorer.
In the described step 1), also comprise the step of the flaw, sign and the outward appearance situation that record testing sample.
In the described step 4), the time that textile calico is immersed in the NaCl solution is 1min.
In the described step 6), the time that will put into baking oven with the testing sample that textile calico wraps is 24h.
In the described step 7), also comprise contamination, the variable color of recording testing sample, corrode or the situation of getting rusty, and the staining situation that records textile calico.
Beneficial effect of the present invention: by choosing two identical metal parts, make it respectively as specimen to be detected and be used for the control sample of comparing with this specimen, specimen is wrapped with the textile calico that is soaked with dilute sodium chloride solution, and place accelerated corrosion, test under the condition of getting rusty, specimen and control sample after will processing at last compare, specimen is stain significantly, variable color, corrosion or the situation of getting rusty etc. are estimated, thereby realized the antirust, anti-corrosive performance of the metal parts that uses on the dress-goods is tested and estimated, avoided metal-ware because of corrosion or produced rusty stain etc. causing contamination to the clothing product; In addition, metal rust preventing anti corrosion test method of the present invention not only operates very simple, convenient, and test result is simple and clear, is worthy of popularization.
[embodiment]
Further specify below below in conjunction with embodiment the present invention being done:
Embodiment 1
One, sample is prepared:
Choose two identical metal parts, one of them is as testing sample, and another is sample in contrast, and the flaw of detail record testing sample, sign and outward appearance situation.
Two, pre-service environment: temperature is 21 ± 2 ℃, and relative humidity is 65% ± 2%
Specimen is placed in this pre-service environment, and left standstill at least 4 hours.
Three, testing procedure:
1. configuration concentration is 1% NaCl solution, with this NaCl solution textile calico is soaked fully, and soaks 1min;
2. after immersion is finished, textile calico is taken out, gently extrude solution unnecessary on the textile calico, make it not have the solution drippage to get final product;
3. with the textile calico that soaks testing sample is wrapped, so that the surface of contact between testing sample and the textile calico should be large as far as possible;
4. the testing sample that wraps is put into temperature and be 38 ± 1 ℃ baking oven, be 24h standing time.
Four, test result:
Testing sample is taken out from baking oven, in same field of view, with the naked eye compare testing sample and control sample, record significantly contamination of testing sample, variable color, corrode or the situation of getting rusty, and the staining situation that records textile calico, the evaluation testing sample reaches the difference of comparing with control sample with respect to before processing, and difference is larger, and then rust resistance and corrosion resistance is poorer.
Five, adopt following yardstick to evaluate its difference, to represent gradually variation of rust resistance and corrosion resistance:
Almost unchanged: as not change or change insignificant
Slightly: slight variation is arranged
Medium: as to change
Seriously: significant change is arranged
The present invention is not subjected to the restriction of above-mentioned embodiment, and other any do not deviate from change, the modification done under Spirit Essence of the present invention and the principle, substitutes, combination, simplify, and all should be the substitute mode of equivalence, is included within protection scope of the present invention.
