25 Ppi Filtre K\u00f6p\u00fc\u011f\u00fc<\/strong><\/p>\n

25Ppi Filter Foam has 25 small holes in one square inch. The larger the value, the smaller the hole.
\nFilter Foam Ppi refers to the number of honeycomb holes on a square inch of Ceramic Foam Filter.
\nGenerally, 15-20 PPI means a large hole, 25-30 PPI is a medium hole, and 35 PPI or more is a small hole.<\/p>\n

In the Chinese standard, 25Ppi Filter Foam is not a regular model.<\/strong>

How to choose the correct Ceramic Foam Filter<\/strong>
\nIf you want 25Ppi Filter Foam, pls contact sales@adtechamm.com
\n1.There are many impurities, and the quality of cast products is general.
\nCeramic filter plates with larger meshes are available, and a glass cloth coarse filter is added in front of the filter plates.
\nAt this time, semi-continuous casting is important for coarse filtration with a glass cloth.
\nIt can intercept the slag from the opening of the eye and the slag washed out by the launder to prevent clogging of the filter plate.
\n2.The quality of aluminum casting products is high, and the new type of foam ceramics with large mesh size is selected.
\n3.The specification of the ceramic filter plate is determined by the flow rate and total throughput of the aluminum melt.
\n4.The color is pure and no impurity, indicating that the material is uniform; the hand is not sticky, indicating that the surface is not sprayed with adhesive, and will not cause secondary pollution.
\n5.The effective specific surface area or porosity calculation of the foam should be carefully evaluated when purchasing the filter.
\nThe mesh surface homogenization state of the filter plate can be observed, and then the cross-sectional mesh homogenization state is observed.
\nM\u00fcmk\u00fcnse, g\u00f6zeneklilik drenaj y\u00f6ntemi ile hesaplanabilir.
\nThe three-dimensional mesh is homogeneous and the porosity is relatively large, which is an excellent ceramic filter plate.<\/p>\n

\u015eu anda g\u00f6zeneklili\u011fi belirlemeye y\u00f6nelik iki temel y\u00f6ntem bulunmaktad\u0131r.
\nBunlardan biri, Ar\u015fimet yasas\u0131na g\u00f6re filtre plakas\u0131ndaki deli\u011fin hacmini hesaplamakt\u0131r; yani, su ta\u015fma borusundan d\u0131\u015far\u0131 akmaya ba\u015flayana kadar ta\u015fma borusu bulunan cam beher i\u00e7ine su enjekte edilir ve su art\u0131k d\u0131\u015far\u0131 akmad\u0131\u011f\u0131nda \u00f6l\u00e7\u00fcm yap\u0131l\u0131r. T\u00fcm numuneler suya dikkatlice yerle\u015ftirilir, ard\u0131ndan su ta\u015fma borusundan d\u0131\u015far\u0131 akar ve bu k\u0131s\u0131mdaki su hacmi \u00f6l\u00e7\u00fcl\u00fcr. Ta\u015fan suyun hacmi, filtre plakas\u0131n\u0131n fiziksel hacminden \u00e7\u0131kar\u0131l\u0131r; bu da filtre plakas\u0131ndaki deliklerin toplam hacmidir.
\nBa\u015fka bir y\u00f6ntem ise, test edilecek numunenin ger\u00e7ek yo\u011funlu\u011funu ve y\u0131\u011f\u0131n yo\u011funlu\u011funu ayr\u0131 ayr\u0131 belirlemek ve ard\u0131ndan a\u015fa\u011f\u0131daki form\u00fcle g\u00f6re numunenin g\u00f6zeneklili\u011fini hesaplamakt\u0131r.
\nThese two methods have their own advantages and disadvantages. The method of operation is simple and convenient, and the detection speed is fast, but its fatal weakness is due to the water absorption characteristics of the filter plate material itself, so that the volume of water discharged is smaller than the actual one. This causes the measured data to be too small.
\n\u0130kinci y\u00f6ntemin test s\u00fcreci daha karma\u015f\u0131k olsa da, test s\u0131ras\u0131nda filtre plakas\u0131 malzemesinin su emiliminin etkisi ortadan kald\u0131r\u0131l\u0131r ve elde edilen veriler nispeten do\u011frudur.
\nBu standartta g\u00f6zeneklilik indeksi 84%\u2019den fazla olarak belirlenmi\u015ftir.<\/p>","protected":false},"excerpt":{"rendered":"
