Embodiment 1
[0026] The preparation method of the skin fiber paper filter material of the present embodiment is prepared through the following steps:
[0027] (1) Preparation of paper base: take a commercially available pulp board, undergo hydraulic pulping and dispersing, and refine it twice with a KRK high-consistency disc refiner. The pulp concentration is 10% by mass and the disc grinding gap is 0.1 mm. , and then refined on a PFI refiner, the slurry concentration is 5% by mass, and the beating degree is 40 ºSR. After adding conventional additives to the slurry, it is made on a paper sheet forming machine, and the paper sheet is dried for later use. , control the weight of the paper to be 37±1 g / m 2 , the thickness is 0.12±0.02 mm;
[0028] (2) Preparation of the coating solution: mix black plum and olive fruit according to the mass ratio of 3:7, mix and crush them, and then heat reflux extraction with water to obtain the extraction solution. The solid-liquid ratio (w / v) during extrac...
Embodiment 2
[0032] The preparation method of the skin fiber paper filter material of the present embodiment is prepared through the following steps:
[0033] (1) Preparation of paper base: Take the commercially available pulp pulp board after hydraulic pulping and dispersing, and refine it twice with a KRK high-consistency disc refiner. The pulp concentration is 15% by mass and the disc grinding gap is 0.2 mm. , and then refined on a PFI refiner, the slurry concentration is 8% by mass, and the beating degree is 30 ºSR. After adding conventional additives to the slurry, it is made on a paper sheet forming machine, and the paper sheet is dried for later use. , control the weight of the paper to be 37±1 g / m 2 , the thickness is 0.12±0.02 mm;
[0034] (2) Preparation of the coating solution: take ebony and olive fruit, mix and crush them according to the mass ratio of 7:3, and then carry out heat reflux extraction with water to obtain the extract solution. The solid-liquid ratio (w / v) during...
Embodiment 3
[0038] The preparation method of the skin fiber paper filter material of the present embodiment is prepared through the following steps:
[0039] (1) Preparation of paper base: take a commercially available pulp board, undergo hydraulic pulping and dispersing, and refine it twice with a KRK high-consistency disc refiner. The pulp concentration is 12% by mass and the disc grinding gap is 0.14 mm. , and then refined on a PFI refiner, the slurry concentration is 6% by mass, and the beating degree is 35 ºSR. After adding conventional additives to the slurry, it is copied and formed on a paper sheet forming machine, and the paper sheet is dried for later use. , control the weight of the paper to be 37±1 g / m 2 , the thickness is 0.12±0.02 mm;
[0040] (2) Preparation of the coating liquid: Take ebony and olive fruit according to the mass ratio of 4:6, mix and crush them, and then heat reflux extraction with water to obtain the extract liquid. The solid-liquid ratio (w / v) during ext...
