Embodiment 1

[0018] Dissolve 5 grams of potassium permanganate in an appropriate amount of pure water, add 5 grams of emulsion binder, weigh 35 grams of nano-bamboo charcoal, 50 grams of basic alumina, and 5 grams of ammonium chloride, and soak them in potassium permanganate solution , stirred for 1 hour, after being fully infiltrated, took out and dried in vacuum at room temperature for 5 hours to obtain gas scavenger A. Take 1 gram of gas scavenger A and put it in a place containing 0.1mg / m 3 In the air environment of formaldehyde, the environmental space is 3m 3， After 24 hours, the formaldehyde gas content in the environmental space has dropped to 0.005mg / m 3 ,

[0019] Environmental pollution gas content in line with national standards.

Embodiment 2

[0021] Dissolve 5 grams of potassium permanganate in an appropriate amount of pure water, add 5 grams of emulsion binder, weigh 35 grams of nano-bamboo charcoal, 50 grams of magnesium hydroxide, and 5 grams of ammonium chloride, all soaked in the potassium permanganate solution, Stir for 5 hours, and after fully infiltrating, take it out and dry it under vacuum at room temperature for 5 hours to obtain gas scavenger B. Take 1 gram of gas scavenger B and put it in a place containing 0.1mg / m 3 In the air environment of formaldehyde, the environmental space is 3m 3， , 24 hours later, the formaldehyde gas content in the ambient space was reduced to 0.004mg / m 3 , the environmental pollution gas content meets the national standard.

Embodiment 3

[0023] Dissolve 6 grams of potassium permanganate in an appropriate amount of pure water, add 5 grams of emulsion binder, weigh 35 grams of nano-bamboo charcoal, 50 grams of magnesium hydroxide, and 4 grams of ammonium chloride, all soaked in the potassium permanganate solution, After being fully infiltrated, take it out and dry it under vacuum at room temperature for 5 hours to obtain gas scavenger C. Take 1 gram of gas scavenger C and place in a place containing 0.1mg / m 3 In the air environment of formaldehyde, the environmental space is 3m 3， , 24 hours later, the formaldehyde gas content in the environmental space was reduced to 0.003mg / m 3 , the environmental pollution gas content meets the national standard.

Abstract

The invention relates to a hospital formaldehyde pollution scavenger and its preparation method. The preparation method provided by the invention comprises the steps of: uniformly mixing nanometer bamboo charcoal or modified nanometer bamboo charcoal with raw materials according to the following weight percentage, adding 10-20% of water for complete infiltration, and carrying out vacuum drying at normal temperature, wherein the above components are concretely composed of, by weight, 30-60 wt% of nanometer bamboo charcoal or modified nanometer bamboo charcoal, 1-10 wt% of potassium permanganate, 30-60 wt% of alkaline aluminum oxide or magnesium hydroxide and 1-10 wt% of ammonium chloride. The invention belongs to the integrated technical field of environmental medicine, environment and human health and new materials. The product provided by the invention is mainly used to eliminate the harm of the formaldehyde pollution under special circumstances of hospitals, and is beneficial to protect the health of medical workers and patients.

Description

technical field [0001] The invention relates to comprehensive technical fields such as environmental medicine, environment and human health, new materials, and plant extraction biotechnology, and particularly relates to the removal of formaldehyde pollution in a special hospital environment and the preparation method of related products. Background technique [0002] Formaldehyde has strong bactericidal power, broad spectrum, and is easy to use. It is a medical disinfectant commonly used in hospitals. In the pathology department of the hospital, formaldehyde solution is widely used in the preservation of specimens. These specimens were packed in containers of different sizes. Some containers had no suitable lids, or even lacked lids. The formaldehyde solution was directly exposed to the air, and the biopsy specimens had to be fixed for more than ten hours after they were sent to the pathology department before they could be taken, dehydrated, Transparent, paraffin-embedded,...
