Embodiment 1
[0034] The invention discloses a method for preparing an ultra-high-precision fiber felt, which comprises the following steps:
[0035] Step 1) plying superfine fibers with a wire diameter of 2 μm and a core number of 15,000 cores;
[0036] Step 2) using the air-laid felting equipment to carry out non-woven laying of the superfine fibers after plying in step 1) to form a superfine fiber web;
[0037] Step 3) uniformity inspection is carried out to the microfiber web in step 2);
[0038] Step 4) Utilize the qualified superfine fiber web and coarse fiber web in step 3) to make a fiber mat, wherein the filtration accuracy of the coarse fiber web is 40-100 μm, and the total unit weight of the fiber mat is 950-1000 g / m 2 ;
[0039] Step 5) rolling the fiber mat blank in step 4) in a smoothing machine;
[0040] Step 6) separating the fiber mat blanks after step 5) with an isolation layer, and sending them into a vacuum sintering furnace for diffusion welding;
[0041] Step 7) Se...
