specific Embodiment approach 1
[0026] Embodiment 1: In the air-spinning ceramic false-twist disc described in this embodiment, the inner surface of the false-twist disc is coated with a layer of ceramic film, and the material of the layer of ceramic film contains a volume fraction of 80% to 90%. Al between 2 O 3 , the thickness of this layer of ceramic film is between 20μm and 70μm, the hardness is between HV1500 and HV1600, and the roughness is between Ra2μm and Ra3μm.
[0027] In this embodiment, the ceramic membrane removes 80% to 90% of the Al contained 2 O 3 , with a surplus of SiO 2 and impurities.
specific Embodiment approach 2
[0028] Specific implementation two: refer to figure 1 , figure 2 and image 3 Specifically describe this embodiment, the method for ceramizing the inner surface of the false twist disc described in this embodiment, which includes the following steps:
[0029] Step 1: Prepare an oxide ceramic layer on the surface of the false twist disc 5, and the specific process is as follows:
[0030] Fix the false twist disc 5 to be processed on the bracket 4, then immerse the false twist disc 5 and the bracket 4 into the reaction tank 3 filled with the working liquid 6 as a whole, and ensure that the opening of the false twist disc 5 to be processed is the same as the one. The working fluid level is parallel;
[0031] According to the thickness of the film layer of the false twist disc 5 to be obtained, the voltage of the DC pulse power supply 1 is set, and then the DC pulse power supply 1 is used to apply a DC pulse between the bracket 4 and the reaction tank 3;
[0032] Use the inne...
specific Embodiment approach 3
[0044] Embodiment 3: This embodiment further describes the method for ceramizing the inner surface of the false-twist disc described in Embodiment 2. In this embodiment, before step 1, the false-twist disc 5 to be treated is firstly processed. Cleaning, the cleaning method is:
[0045] First, use deionized water to clean the false twisting disc 5 to be treated, and then use alcohol solution to clean the false twisting disc 5 after deionized water cleaning to obtain a false twisting disc 5 with surface dust and oil stains removed.
[0046] Specific implementation four: refer to Figure 4 This embodiment is specifically described. This embodiment further describes the method for ceramicizing the inner surface of the false-twisting disc described in the third embodiment. A periodic process of applying a DC pulse to the reaction tank 3 is:
[0047] At time t0, the DC pulse power supply 1 outputs a positive pulse with an amplitude of Vzi and a pulse width of Tz; at the end of the...
