Embodiment Construction

[0012] Referring to the accompanying drawings, the catalyst fresh-keeping block includes an activated carbon adsorbent substrate 3, and the surface of the substrate is provided with a non-woven packaging bag 1 added with an antibacterial agent. The bottom surface of the matrix is ​​provided with a fiber mesh layer 2 for preventing the matrix from breaking. When the matrix has multiple layers, multiple layers of fiber nets can be arranged alternately.

[0013] The production method of the fresh-keeping block matrix is ​​as follows: firstly, put the powdered palladium and activated carbon in a closed container and stir, so that the powdered palladium is fully adhered to the surface of the activated carbon to make palladium-impregnated carbon. Then mix copper oxide, manganese dioxide, polyethylene, silicon dioxide and palladium-impregnated carbon evenly and fill it into the mold, then heat and sinter, and take it out after cooling to get the product. The formed products can be u...

Abstract

A refrigerator catalytic freshness-keeping block is a bonded block-like material which is made up by adding active carbon matrix of catalyst through the process of heating, thawing and cooling, and on matrix surface, the fabric layer with antibacterial agent is added. The main composition of said invention includes polyethylene, manganese oxide, palladium, cupric oxide, silicon dioxide and active carbon. The catalyst components in the freshness-keeping block can adsorb olifiant gas in fruit-vegetable chamber of refrigerator greatly, then the adsorbed olifiant gas can produce oxidation reaction with oxygen gas and decomposed into water and carbon dioxide. Said freshness-keeping block is packaged with non-woven fabric with antibacterial agent, and said antibacterial agent can be slowly released so as to prolong freshness-keeping period.

Description

technical field [0001] The invention relates to a catalyst fresh-keeping block suitable for a refrigerator and a manufacturing method thereof. Background technique [0002] Existing refrigerator deodorization fresh-keeping has multiple forms and approach. Some use activated carbon adsorbents to absorb the odor molecules produced by the food in the refrigerator; The thermal decomposition catalyst catalyst adsorbs and decomposes the odor molecules of the refrigerator. Most of them have short life of deodorization function or complex structure. The "refrigerator catalyst deodorizer" disclosed in Chinese Patent No. 982336144 mainly includes three parts: a deodorizing catalyst, a casing and a filter screen. Between the catalyst and the shell. Its structure is also more complicated, and can not effectively regulate the humidity of refrigerator fruit and vegetable room. Contents of the invention [0003] The purpose of the present invention is to provide a catalyst fresh-kee...
