Problems solved by technology

[0003] The traditional central air-conditioning filter system is only for coarse mesh filtration, and the effect on filtering PM2.5 is very small, almost zero. However, the traditional high-efficiency air filter paper is used as the filter material, which is not only expensive, but also has a low dust holding capacity. Low, short service life, not very suitable for central air conditioning filter system

Abstract

The invention discloses a manufacturing method of a special high-efficiency filter material for central air conditioning. The method comprises the following steps: proportionally selecting zinc oxide, borax, white sand, potassium feldspar powder, sodium carbonate, calcite, potassium carbonate and barium carbonate, and uniformly mixing; heating to melt the raw materials to form a glass liquid, and spraying the glass liquid with flame to prepare glass fiber wool; directly laying the glass fiber wool on the polytetrafluoroethylene surface by using an air flow forming machine and a paving head to form a composite, and carrying out spray sizing and drying on the composite to obtain the finished product. The glass fiber wool is directly laid on the polytetrafluoroethylene film by a dry forming process, thereby greatly enhancing the acid resistance, alkali resistance and weather resistance of the filter material, and also enhancing the strength of the filter material. The special high-efficiency filter material for central air conditioning, which is 0.4-10mm thick, is produced according to the demands of customers.

Description

technical field [0001] The invention belongs to the field of air filtration, and relates to a glass fiber air filter material, in particular to a method for making a special high-efficiency filter material for a central air conditioner. Background technique [0002] With the rapid development of society, the combustion of fossil fuels (coal, gasoline, diesel), biomass (straw, firewood) and waste incineration. It is converted into PM2.5 in the air, making the content of PM2.5 very high. PM2.5 mainly causes damage to the respiratory system and cardiovascular system, including respiratory irritation, coughing, dyspnea, reduced lung function, aggravation of asthma, chronic bronchitis, arrhythmia, non-fatal heart disease, heart and lung disease patients die prematurely. [0003] The traditional central air-conditioning filter system is only for coarse mesh filtration, and the effect on filtering PM2.5 is very small, almost zero. However, the traditional high-efficiency air filt...
