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:
The invention belongs to a kind of preparation technology of filtering product, particularly a kind of high efficient PE filter element and production technology thereof.
Background technology:
The present complex manufacturing of PE filter element, low, the acidproof alkaline error of the filtering accuracy of product, porosity be low, poisonous, can produce automatic pollution, be difficult for the not reproducible regeneration of blowback uses, and the cost of manufacture height.
Summary of the invention:
Purpose of the present invention just is to provide a kind of production technology of high efficient PE filter element, and this production technology is simple, and the filter element acid and alkali-resistance of producing, porosity height, nontoxic, no automatic pollution, easily blowback renewable repeated use.
Technical scheme of the present invention is: a kind of high efficient PE filter element and production technology thereof is characterized in that: selecting the ultra high molecular polyethylene powder for use is filter medium, in the mould of packing into then, puts into the heating furnace sintering at last, and taking-up, cooling, the demoulding get final product.
The present invention can also adopt following technical measures:
Add salt or alkali in the above-mentioned ultra high molecular polyethylene powder.
Above-mentioned ultra high molecular polyethylene powder is selected for use between the 20-200 order.
The weight proportion of above-mentioned salt or alkali is 1-60%.
Above-mentioned sintering temperature is between 180-300 ℃, and sintering time is between 10-150 minute.
Advantage of the present invention is: simple, the easy row of production technology.The high efficient PE filter element good toughness of producing, acid and alkali-resistance, difficult broken, filtering accuracy is 0.3-150 μ m.Owing to added salt or alkali solid particle at the ultra high molecular polyethylene powder, therefore increased porosity, be 48-54%, pressure will be 0.03 μ Pa.Nontoxic, no automatic pollution, easily blowback renewable repeated use.
The specific embodiment:
Embodiment 1: selecting 60-120 order ultra high molecular polyethylene powder for use is filter medium, and adds the 5%Nacl particle therein, in the stainless steel mould of the Φ 38 * 1500 that packs into then, put into the heating furnace sintering at last, temperature is controlled at 240 ℃, and sintering is after 90 minutes, and taking-up water-cooled, the demoulding get final product.Product is Φ 38 * 1500,5 μ m PE filter elements.
Embodiment 2: selecting 60-120 order ultra high molecular polyethylene powder for use is filter medium, and adds the 5%Nacl particle therein, in the stainless steel mould of the Φ 360 * 8 that packs into then, put into the heating furnace sintering at last, temperature is controlled at 250 ℃, and sintering is after 60 minutes, and taking-up water-cooled, the demoulding get final product.Product is the PE plate of Φ 360 * 8, and its porosity is 50%.
