Problems solved by technology

[0011] However, filters using Ticona's binder have drawbacks in separating fine, powdery particles from the activated carbon
[0012] In addition, the adhesive is very expensive, so that it will increase the manufacturing cost of the filter

Embodiment 1

[0030] Composition and fabrication method of 3 μm carbon block

[0031] Powdered activated carbon with an average particle size in the range of 60-102 μm is mixed with an isolated binder with a particle size of 20-80 μm. Powdered activated carbon accounts for 10-20% by weight of the total binder. To about 3 ~ 30kgf / cm 2 The mixture was compressed under pressure and heat-treated at 230 °C for 30 min. After the processing is completed, a block shape with pores of about 3 μm is formed. The content of the binder in the block filter is 30 to 35% by weight.

Abstract

A carbon block filter with UHMWPE binders and activated carbons and a manufacturing method therefor are provided. The method comprises: pulverizing ultrahigh molecular weight polyethylene (UHMWPE) binders with an average particle size of 120-140 mum, serving as original binders, and separating binders with a granularity of 20-80 mum from the original binders; mixing the separated binders with the original binders; and forming a carbon block filter by mixing commercial, powdered activated carbons, with the mixed binders. The mixing of the separated binders with the original binders and the forming of the carbon block filter control the powdered activated carbons and the adjusted, UHMWPE binders so that the cumulative granularity ratio of them is 1:0.78-1.1, with respect to a particle size equal to or less than 105 mum. The carbon block filter of the invention acquires import substitution effect and reduces the manufacturing cost by 30-40%.

Description

technical field [0001] The present invention relates to a carbon block filter containing an ultra-high molecular weight polyethylene (UHMWPE) binder and activated carbon, wherein, in their particle size distribution, the particle size is equal to or The particle size ratio of less than 105 μm is 1:0.78~1.1, the purpose is to make the filter have high efficiency performance and be manufactured at a relatively low cost. The invention also relates to a method of making a carbon block filter. Background technique [0002] Traditional activated carbon filters for water purifiers are designed to be filled with powdered activated carbon. When water passes through it, the filter can filter and absorb impurities. However, because they are only set to be filled with powdered activated carbon, the filter layer will produce a meridian phenomenon. This will reduce the removal rate of impurities and cause continuous loss of activated carbon. [0003] Because the surface of activated c...
