preparation example Construction

[0040] The preparation method of air particle filter paper comprises the following steps:

[0041] Step (1): Prepare materials

[0042] The rush core fiber particles: take 65-75 parts of the rush core, grind it to 0.5-1mm with a grinder, and set aside;

[0043] Wood pulp fiber: Take 15-25 parts of wood pulp fiber, dissolve in 500-1000 parts of water, and set aside;

[0044] Amylopectin: take 5-10 parts of amylopectin and set aside;

[0045] Step (2): Plasma knocking

[0046] Mix the above-mentioned rush core fiber particles and wood pulp fibers, add 900-1100 parts of water, beat with a beater for 5 minutes, stop for 2 minutes, and then beat for 5 minutes until there are no pulp lumps, and when the dispersion is uniform, stop beating, and then add the above-mentioned pullulan As a retention aid, stir for 1 minute to obtain a liquid slurry;

[0047] Step (3): Press paper

[0048] Pour the liquid slurry obtained in step (2) into a material basin with a 2mm stainless steel fl...

[0056] Step (1): Prepare materials

[0057] Rush core fiber particles: take 75g of rush core, grind it to 0.5-1mm with a grinder, and set aside;

[0058] Wood pulp fiber: take 15g of wood pulp fiberboard;

[0059] Amylopectin: take 10g of amylopectin and set aside;

[0060] Step (2): Plasma knocking

[0061] Add 900g of water to the wood pulp fiberboard, beat it with dissolving pulp for 5 minutes, and stop for 2 minutes; then knock it for 5 minutes, and after 1 hour, stop beating until there are no pulp lumps and the dispersion is uniform;

[0062] Step (3): Mixing Knocking

[0063] Add the rush core particles into the kneaded wood pulp, and continue knocking for 30 minutes, until the wood pulp fibers are decomposed and melted, and form a link with the rush core particles to form a suspension;

[0064] Step (4) adds above-mentioned 10g pullulan as retention aid again, stirs 1 minute, obtains liquid slurry;

Abstract

The invention discloses air particle filter paper based on juncus effusus core fiber grains and a preparation method thereof, aiming at solving the problems in the prior art that the filtering efficiency on particles of PM2.5 (Particulate Matter 2.5) or below is relatively poor, the air resistance is great and the degradation performance is poor. The air particle filter paper is prepared from thefollowing substances in parts: 65 to 75 parts of the juncus effusus core fiber grains, 15 to 25 parts of plant fibers and 5 to 10 parts of a retention auxiliary agent. The preparation method comprisesthe following five steps: preparing materials, beating, carrying out papermaking, pressing paper and drying. The air particle filter paper provided by the invention is produced by utilizing natural juncus effusus cores and has the characteristics of high air permeability and high filtering precision; the filtering rate on the PM2.5 in the air can reach 99 percent or more; in a filtering process,the airflow static pressure is less than or equal to 40pa, so that the air particle filter paper is suitable for being used in haze weather and other air pollution environments.

Description

technical field [0001] The present invention relates to air particle filter paper based on rush wick fiber particles and its preparation method. Background technique [0002] With the development of industrialization, environmental pollution, especially air pollution has become more and more serious. Correspondingly, filter materials for various air particles are also produced one after another. More representative ones include plastic melt-blown web forming technology represented by the US patented product HEPA material, glass fiber filter screen technology, metal membrane separation technology, various micro-filtration and nano-filter paper technologies, plastic mesoporous fiber technology, and traditional plant technology. Fiber filter paper papermaking technology, activated carbon fiber filter paper technology, hydroxyapatite nanowire papermaking technology, etc. [0003] However, there is a common contradiction in air particle filtration, that is, the contradiction be...
