Embodiment 1

[0011] Example 1: Select 60-120 mesh ultra-high molecular polyethylene powder as the filter medium, and add 5% Nacl particles therein, then pack it into a Φ38×1500 stainless steel mold, and finally put it into a heating furnace for sintering, and the temperature is controlled at After sintering at 240°C for 90 minutes, take out the water to cool and demould. The product is Φ38×1500, 5μm PE filter element.

Embodiment 2

[0012] Embodiment 2: Select 60-120 mesh ultra-high molecular polyethylene powder as the filter medium, and add 5% Nacl particles therein, then pack it into a Φ360×8 stainless steel mold, and finally put it into a heating furnace for sintering, and the temperature is controlled at After sintering at 250°C for 60 minutes, take out the water to cool and demould. The product is a Φ360×8 PE board with a porosity of 50%.

Abstract

The invention discloses a highly-efficient PE filter element and the production process. Ultrahigh molecular polyethylene powder is first selected as filter media, then put into a mould, finally put into a heating furnace to sinter, taken out, cooled and demoulded. The invention has the advantages that the production process is simple and easy to operate; the finished highly efficient PE filter element is of good tenacity, acid and alkaline resistant and nonbreakable, with the filter fineness being 0.3-15 0 um; as solid particles of salt or alkali are added in ultrahigh molecular polyethylene powder, the porosity factor is improved to 48-54% and the pressure is reduced to 0.03 uPa; the invention which is free of toxin and self-pollution and easy for backblowing can be regenerated and used repeatedly.

Description

Technical field: [0001] The invention belongs to a preparation process of filter products, in particular to a high-efficiency PE filter element and its production process. Background technique: [0002] At present, the production process of PE filter elements is complex, and the products have low filtration accuracy, poor acid and alkali resistance, low porosity, toxicity, self-pollution, not easy to blow back and cannot be regenerated, and the production cost is high. Invention content: [0003] The purpose of the present invention is to provide a high-efficiency PE filter element production process, which is simple, and the produced filter element is resistant to acid and alkali, has high porosity, is non-toxic, has no self-pollution, is easy to blow back and can be regenerated repeatedly use. [0004] The technical solution of the present invention is: a high-efficiency PE filter element and its production process, which is characterized in that: ultra-high molecular p...
