Technical Engineering Zirconia Ceramic Standard Parts
Reputation depends on quality, quality comes from Hard!
Zirconia Ceramic Structural Parts:
Standard atmosphere for ceramic environment and correction and pre-conditioning, the temperature does not exceed 50 ℃, and the relative humidity is 10% to 25%. The standard atmosphere for humidity control and testing is performed according to GB 6529:
temperature (20±2) °C, relative humidity (65±3)%. Samples and preparation 10g were randomly and uniformly taken from the laboratory samples as test samples, and pre-conditioning and humidity-conditioning were carried out to make the samples reach a moisture absorption balance (the mass gradient of continuous weighing every 30min should not exceed 0.1%). About 500 fibers were randomly taken out from the equilibrated sample and placed evenly on the fleece board for measurement. Procedure and operation Determination of test parameters Nominal gauge length When the nominal fiber length is greater than or equal to 35mm, the nominal gauge length is 20mm; when the fiber nominal length is less than 35mm, it is 10mm.
The stretching speed is set according to Table 1. 1 Fiber stretching speed Set the average fiber elongation at break, % stretching speed, mm/min50% nominal gauge length 100% nominal gauge length 200% nominal gauge length acrylic fiber, polyester: 0.075cN/dtex; polypropylene, Chlorine, nylon: 0.05cN/dtex.
Note: The pre-tension is calculated according to the nominal linear density of the fiber. In the wet test, the pre-tension is half of that in the dry state. If some fibers are not suitable for the above-mentioned pre-tension, they can be determined separately after consultation with relevant departments. 9.1.4 Calculate the linear density According to GB/T 14335 "Test Method for Linear Density of Synthetic Short Fibers", measure the average linear density of the sample. Instrument adjustment Turn on the power switch and preheat for 10 minutes.
