Embodiment 1

[0028]Add 120 kg of waste paper and 2000 kg of water to the beater, soak for a period of time. After the waste paper is softened, start the agitator to break the waste paper. The beating process is 15 minutes. The slurry obtained by mixing and beating the dry fiber is pressed into the pipeline through a vacuum pump, and enters the slurry tank. In the slurry tank, 2.5 kg of hydroxypropyl cellulose (HPC), 0.5 kg of polyacrylamide and polyvinyl alcohol are added at 4:1 The mass ratio of the mixture is mixed uniformly, 0.3 kg of STA paper enhancer, and then 10 kg of aluminum sulfate and rosin glue are mixed at a ratio of 1.5:1. Among them, the rosin glue is pre-dissolved and put in the dissolved When rosin glue, pour it evenly around the slurry tank, stir it for 10 minutes to make it evenly mixed with the slurry, then put in the pre-dissolved aluminum sulfate, stir for another 10 minutes until it is evenly mixed, and finally add 0.9 kg of dissolved in 1% ~3% acetic acid aqueous soluti...

Embodiment 2

[0030] Add 50 kilograms of waste paper and 1000 kilograms of water to the beater, soak for a period of time. After the waste paper is softened, start the mixer to break the waste paper. The beating process is 13 minutes. The slurry obtained by mixing and beating the dry fiber is pressed into the pipeline through a vacuum pump and enters the slurry tank. Add 4 kilograms of aluminum sulfate and rosin gum in a 1.45:1 ratio to the slurry tank, and 0.5 kilograms of antibacterial agent produced from chitosan that has been dissolved in 1% to 3% acetic acid aqueous solution. Stir the slurry tank fully and adjust the slurry concentration to 1.2%. Then it enters the forming machine and is formed by negative pressure and vacuum adsorption by grouting method. After the product is formed, the moisture content is 63%. The semi-finished product was dried in the sun to obtain a product with a moisture content of 13% and basically no wet feeling when touched by hand. Take the dried product, humidi...

Embodiment 3

[0032] Add 80 kilograms of discarded paper such as playing cards and 1500 kilograms of water to the beater, soak for a period of time. After the discarded paper such as playing cards is softened, start the agitator to break the waste paper. The beating process is 10 minutes. The slurry obtained by mixing and beating the dry fiber is pressed into the pipeline through a vacuum pump and enters the slurry tank. Add 4 kg of aluminum chloride, 2 kg of starch, and 0.2 kg of quaternary ammonium salt complex iodine to the slurry tank to adjust the slurry concentration to 0.8%. Then it enters the forming machine and is formed by negative pressure and vacuum adsorption by grouting method. After the product is formed, the moisture content is 72%. The semi-finished product is then dried to obtain a product with a moisture content of 13%. Take the dried product, humidify it with a sprayer, place it in a shaping machine, and shape it by overheating and pressing, the residence time is 2.5 seconds...

Abstract

The present invention relates to one kind of degradable disposable medical nursing material and its production process. The degradable disposable medical nursing material consists of dry fiber 100 weight portions, water repellent 5-9.3 weight portions and antiseptic 0.01-10 weight portions. Its production process includes the steps of: pulping fiber to obtain 1-6 wt% concentration slurry, adding other components, forming to obtain product with water content of 55-80 %, drying to water content of 10-16 %, hot pressing to shape, trimming and packing.

Description

Technical field [0001] The invention relates to a degradable disposable medical care product and a manufacturing method thereof. Background technique [0002] Existing medical care products, such as men's and women's urinals, bedpans, waist basins, vomiting basins, measuring basins, fracture basins, round basins, urine measuring cups, etc., generally use iron, aluminum, plastic and other products, and the quality of the products is relatively heavy. Some cannot be stacked, which is inconvenient to transport and carry. Metal products such as ironware and aluminumware have high raw material prices and large resource consumption, making it difficult to achieve one-time use. It is difficult to avoid that the product will carry some germs during multiple uses, causing cross-infection and re-infection; and metal products are in use. Unrecoverable damage may occur, affecting the use and appearance. If plastic products are used once, the unit price is relatively high, and because of thei...
