Example 3

The process of examples 1-3, comprising the steps of:

The new pure gold and the common pure gold produced according to the production formula and the process of the 24K pure gold in the embodiment 1 are subjected to tension test, a plurality of 0.4mm common 24K gold wires and 0.4mm 24K pure gold wires are selected for tension test, a PB-2000 full-automatic insertion and extraction force tester is selected as a test device, the test document is 24 ℃, the test humidity is 52% RH, the tension speed is 5mm/min, and the test results are as follows:

according to the table, the average value of the tensile force test of the 24K new pure gold thread produced by adopting the formula and the process is obviously greater than the tensile force of the common gold thread, the tensile force of the 24K new pure gold thread is obviously superior to that of the common 24K gold thread, and the 24K new pure gold thread solves the problem that the original gold thread is softer and easy to break.

The new pure gold produced according to example 1 was tested for tensile strength and hardness in the longitudinal direction with 22K normal gold, and a test sample set produced according to the production formulation and process of the present invention was selected: 24K gold wire, 24K0.40 water wave chain, 24K0.40 wide double-lip chain, 24K0.35 flash 0 trillion chain and 24K gold reference sample set produced by general process: 22K gold wire, 22K0.40 water wave chain, 22K0.40 wide double-lip chain and 22K0.35 flash 0 trillion chain.

Firstly, carrying out tensile test on a water wave chain, a double-lip chain and a flash seal 0 trillion chain, wherein the test equipment is an electronic universal tester with the model number of utm5105, the test temperature is 20 ℃, the test humidity is 56% RH, the tensile speed is 5mm/min, and the test results are as follows:

sample type	Common 22K gold breaking force	24K New pure gold breaking force
			0.40 water wave chain	114.58N	39.69N
0.40 wide double-lip chain	44.56N	16.66N
			0.35 flash 0 Wanli chain	37.42N	16.16N

The 22K gold contains only 91.7% of gold, so the breaking force of the 22K gold is higher than that of the 24K gold by one grade, and the difference of the general breaking force is huge, and the 24K gold artware manufactured by the formula and the process is in the same order of magnitude as the breaking force of the common 22K gold artware on the drawing force figure.

Therefore, by comparing the common 24K gold thread transversely with the multi-class gold artware of comparing 22K gold longitudinally, the 24K new pure gold prepared by the formula and the production process of the invention has obvious improvement on the tensile force, and the problem that the common gold artware with high gold content is easy to be pulled, deformed or broken is solved.

And performing Vickers hardness test on the 24K gold wires and the 22K gold wires, wherein the test equipment adopts a micro Vickers hardness tester with the model of BuehlerMicroment 5103, the test temperature is 23 ℃, the humidity is 56% RH, and the test conditions are as follows: load 0.2Kgf and hold for 10 seconds, test results are given in the following table:

as can be seen from the data in the table, the hardness of the 24K new pure gold is very close to that of the common 22K gold wire with higher hardness grade, so that the hardness of the 24K new pure gold prepared by the formula and the production process is also remarkably improved.
