Embodiment Construction
[0030] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0031] A method for producing a medical filter element, comprising the following processing steps:
[0032] (1) Raw material preparation: use a ceramic slurry to impregnate one or more base paper carrier webs, and then fire them;
[0033] (2) Discount and fold: Discount and fold the prepared filter element, and repeat the operation several times;
[0034] (3) Edge sealing: carry out edge sealing on the folded raw filter material;
[0035] (4) Edge trimming: cut off the excess edge material of the filter element material that has been edge-sealed;
[0036] (5) Heat-sealed end cap: Heat-seal both ends of the edge-cut filter element through a heat-sealing machine, and install the end cap after heat-sealed;
[0037] (6) Flushing: Put the heat-seale...

The invention discloses a production method of a medical filter element. The production method comprises the following processing steps: raw material preparation, folding, folding, edge sealing, edgecutting, end cover heat sealing, flushing, integrity detection, drying, interface extension and packaging and delivery, and at least one carrier web of the raw paper carrier webs has different thicknesses and / or structures in width and / or length. The filter element is placed below the flushing head and then flushed for at least 2-5 min, multiple times of overturning and repeated cleaning are needed during flushing, and the temperature of the filter element is 150-200 DEG C. The invention relates to the technical field of filter element production. According to the production method of the medical filter element, firstly, the non-ceramic medium winding body can comprise the flat layer and the corrugated layer so that the strength of the filter element can be guaranteed, the quality and theyield of the produced filter element can be guaranteed by adopting the process flow, the produced filter element is detected and treated, and the damaged filter element is effectively prevented from flowing into the market.
Description
technical field [0001] The invention relates to the technical field of filter core production, in particular to a production method of a medical filter core. Background technique [0002] The filter element separates solid particles in liquid or gas, or fully contacts different material components to speed up the reaction time, which can protect the normal operation of the equipment or the cleanliness of the air. When the fluid enters the filter element with a certain specification filter, its impurities are blocked. , while clean fluid exits through the filter element. The liquid filter element makes the liquid (including oil, water, etc.) clean to the state required for production and life, that is, to make the liquid reach a certain degree of cleanliness. At present, in the pharmaceutical production process, the filter element is generally dry. After cleaning, the operator holds the filter element in one hand and a compressed air gun in the other hand, and uses oil-free ...
