Abstract
The invention discloses a biological agent for removing low-content formaldehyde and belongs to the field of air purifying. According to the biological agent, natural chlorophytum comosum leaves are subjected to a series of steps of immersing, slight washing, air dying, ultraviolet lamp disinfecting and sterilizing, rolling, mashing, filtering and the like, and then chlorophytum comosum elements are obtained; water, magnesium chloride, agar and protein are added to the chlorophytum comosum elements to be mixed, and a micelle wrapping form is formed; and the mixture is mixed with a binding agent, and then the biological agent is prepared. The biological agent has the advantages that the biological agent is formed by preparing the chlorophytum comosum elements extracted from the natural plant of chlorophytum comosum, the effect of decomposing formaldehyde with the concentration smaller than 10 mg/m<3> of the biological agent in a room is obvious, and the formaldehyde can be removed more thoroughly; five months later, the indoor formaldehyde concentration is reduced to 0.05 mg/m<3> from 10 mg/m<3>; and the plant resources are effectively utilized, cost is saved, and the biological agent is worthy of application and popularization.
Description
Technical field

(2) the bracketplant leaf after cleaning is carried out air-dry under ventilation state, adopt uviol lamp to carry out disinfection sterilization processing 30 ~ 60min, removing harmful substance;
(3) the bracketplant leaf that above-mentioned disinfection completes is placed in container, carries out spreading, smash to pieces, by filtered through gauze, obtain filtrate;
(4) in above-mentioned filtrate, add 5 ~ 10g calcium carbonate, 30 ~ 50mL acetone soln mixes, carry out chromatogram multi_layer extraction and go out bracketplant element;
(5) bracketplant element is moved in another container, add 15 ~ 20mL water, 5 ~ 10g magnesium chloride, 5 ~ 10g agar and 5 ~ 10g protein and mix, place 1 ~ 3 day under room temperature, illumination condition, make it be micelle coated;
(6) in above-mentioned colloid mixture, add 8% ~ 14% adhesive, adjust ph is 5 ~ 7, stirs, obtained biologic product;
(7) by obtained biologic product in frequency be 25HZ ~ 55HZ condition under ultrasonic 10 ~ 35min, then join in autoclave, be filled with 2% ~ 40% nitrogen.
Described adhesive is in carboxymethyl cellulose, dimethyl silicone polymer and polyacrylate two or three, and its mass ratio is 20 ~ 80% carboxymethyl celluloses, 20 ~ 80% dimethyl silicone polymers and 20 ~ 80% polyacrylate.
Application process of the present invention: biologic product is sprayed one deck on the indoor wall newly fitted up or household articles, a spray in month once.
The present invention is compared with additive method, and Advantageous Effects is:
(1) adopt natural plants bracketplant to extract the plain biologic product be prepared from of bracketplant, 10mg/m is less than to indoor concentration
3formaldehyde remove more thorough;
(2) effectively plant resources can be utilized, cost-saving.
