Embodiment 1

[0032] This embodiment discloses a method of steam spraying a melt-blown cloth capable of inactivating viruses, comprising the following steps:

[0033] Step 1. Mix the virus-inactivating powder with water and heat to generate high-temperature steam; the mass ratio of the virus-inactivating powder to water in step 1 is 1:3. The powder that can inactivate the virus described in step 1 includes but is not limited to the powder that can inactivate the new coronavirus, preferably a porous solid material for inactivating the virus produced by the Institute of Chemistry and Physics, Chinese Academy of Sciences, the publication number CN1552454A, a kind for Porous solid material for adsorbing and inactivating viruses and its application. The true diameter of the novel coronavirus inactivated particles is 5-10 μm. The specific gravity is close to that of water, insoluble in water, melting temperature above 1000°C, non-toxic, tasteless and harmless white powder. The content of powder...

Abstract

The invention provides melt-blown cloth capable of inactivating virus, a steam spraying method, a production line and application. The steam spraying method of the melt-blown cloth capable of inactivating the virus comprises the following steps of 1, mixing powder capable of inactivating the virus with water, and carrying out heating to generate high-temperature steam; 2, uniformly spraying the high-temperature steam on the surface of the preheated melt-blown cloth, and enabling the powder capable of inactivating the virus to permeate into the melt-blown cloth through the hot melting principle; and 3, performing high-temperature extrusion drying on the melt-blown cloth, and finally carrying out coiling and packaging. The invention further discloses the steam spraying production line of themelt-blown cloth capable of inactivating the virus. The steam spraying production line comprises a suction fan, a high-temperature compression roller, a drying guide shaft, a material receiving roller, a steam nozzle, a high-temperature gas nozzle, a flow powder concentration monitoring instrument, a steam generator and a liquid stirring machine. According to the steam spraying method of the melt-blown cloth capable of inactivating the virus, effective combination of the powder capable of inactivating the virus and the melt-blown cloth can be achieved.

Description

technical field [0001] The invention relates to the preparation technology of melt-blown cloth, in particular to a melt-blown cloth capable of inactivating viruses, a steam spraying method, a production line and its application. Background technique [0002] Melt blown cloth is a filter material with polypropylene as the main raw material. The fiber diameter can reach 1-5 microns. These ultra-fine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the melt-blown cloth has good filtration, shielding, heat insulation and oil absorption. It can be used in air and liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials and wiping cloths. Melt blown cloth is the core material of the mask. Medical masks and N95 masks are composed of spunbond layer, meltblown layer and spunbond layer. Among them, the spunbond layer and meltblown layer are all made of polypropylene ...
