Abstract
The present invention relates to an active microfiltration bacteriostatic sintered film and its production method, belonging to the field of environment-protecting water and air purification. Said sintered film is composed of base material and auxiliary material, in which the base material adopts superhigh molecular weight polyethylene, and the auxiliary material adopts silver-carried active carbon, active carbon fibre, carbon black and activating agent. At least one non-metal granular adsorption material, superhigh molecular weight polyethylene, active carbon fibre and activating agent, etc. are undergone the processes of pulverizing, uniformly mixing, extruding, moulding and roasting so as to obtain the invented product.
Description
Technical field
The invention belongs to environmental protection water, gas field of purification, particularly relate to antibacterial sintered membrane of a kind of active microfiltration and manufacture method thereof.
Background technology
At present, therefore industrial wastewater, sanitary sewage, agricultural chemicals etc. will carry out environmental protection treatment to it to causing serious pollution in the water source.The filter medium that uses in the process of purifying waste water at present is of a great variety.Generally adopt active material and sorbing material to be made, and obtained approval, its preparation method is: be made up of base material, auxiliary material and additive, its base material is generally selected one or more the combination in polyvinyl resin, acrylic resin, the rubber etc. for use, and auxiliary material and additive are selected from activated carbon, activated carbon fiber, glue and connect two or more combination in the raw material such as agent, diatomite, pottery.And with above-mentioned base material auxiliary material and additive through pulverizing, mixing, mold pressing or extrusion modling, various filter cores are made in roasting, the demoulding.Though the stronger effect that this filter core filters, adsorbs the organic matter in liquid, the gas, and adsorption capacity is big, and concentration range is wide.But exist the most outstanding shortcoming in actual use be, in case adsorb saturated after, at this moment operating pressure raises, water yield decline water quality is also unstable, filter core is partial blockage, need carry out backwash and remove block and be adsorbed on slag class materials such as foreign material on the filter core, organic matter,, form " biomembrane " because microbial bacteria such as bacterium has been adsorbed on breeding growth among the filter core in the organic matter." biomembrane " do not play biodegradation in physical filtering, can only be the resistance that filters, and this reactive resistance is difficult to solve with the normal wash way.
Summary of the invention
The purpose of this invention is to provide a kind of to filtration of the organic matter in the water and adsorption function excellence, can reduce and delay the formation of " biomembrane " effectively, and adsorption capacity is big, concentration range is wide, antibacterial, bactericidal effect good, antibacterial sintered membrane of the active microfiltration of long service life and manufacture method thereof.
The object of the present invention is achieved like this, this sintered membrane is made up of base-material and auxiliary material, have a kind of non-metallic particle sorbing material, ultra-high molecular weight polyethylene, activated carbon fiber, activator etc. at least, through pulverize, be mixed, roasting forms after the extruding, packing compact forming, the weight ratio that it is characterized in that raw material proportioning and each component is respectively: base-material adopts ultra-high molecular weight polyethylene, addition accounts for 68%～85%, and auxiliary material adopts particle or powdery to carry silver-colored activated carbon, and addition is 5%～10%; Activated carbon fiber, addition are 10%～19%; Carbon black, addition are 1%～2%; Activator, addition are 0.5～1%.
According to the antibacterial sintered membrane of active microfiltration of the present invention, its activated carbon fiber adopts iodine sorption value: 700～1500mg/g, specific area: 1100～1600m
2/ g, serge blue adsorptive value 〉=200mg/g.
The preparation technology of the antibacterial sintered membrane of active microfiltration of the present invention is as follows:
(1) by above-mentioned raw materials and weight proportion and weigh,
(2) the base-material ultra-high molecular weight polyethylene is sized to 60～120 orders,
(3) auxiliary material carries silver-colored activated carbon by fruit stone matter, being sized to 20～50 orders, activated carbon fiber, carbon black, activator combines, above-mentioned auxiliary material and base-material are mixed, the interior extrusion modling of the mould of packing into, and in three temperature provinces of (80 ℃～100 ℃)-(135 ℃～155 ℃)-(185 ℃～205 ℃), carry out low-in-the high-order formula of passing heats up, is incubated, heats and come out of the stove behind the sintering, carries out the water logging quenching then, withdrawing pattern promptly gets sintered membrane of the present invention.
Advantage of the present invention is, owing to adopted a year silver-colored activated carbon to substitute common activated carbon, not only reduce and delay the formation of " biomembrane " effectively, and silver ion has also suppressed the breathing of bacterium in fiber holes, cause the bacterium maimed person can not growth and breeding, to organic matter adsorption function excellence, can purify waste water, gas, suspension and bacteria impurities in the water body removed at the end, and long service life.
The specific embodiment
The invention will be further described below in conjunction with embodiment.
Embodiment 1
Get base-material: adopt 60～120 purpose ultra-high molecular weight polyethylenes, addition accounts for 73%, auxiliary material: adopt graininess to carry silver-colored activated carbon, addition is 10%; Powdered activated carbon fiber, addition are 15%; Its activated carbon fiber adopts iodine sorption value: 700～1500mg/g, specific area: 1100～1600m
2/ g, serge blue adsorptive value 〉=200mg/g.Its carbon black, addition are 1.5%; Activator, addition is 0.5%, and above-mentioned auxiliary material and base-material are mixed, after the interior extrusion modling of the mould of packing into, first design temperature is 80 ℃ in heating furnace, be incubated 30 minutes, transfer to 135 ℃ again, be incubated 40 minutes, transfer to 185 ℃ at last, come out of the stove after 130 minutes, carry out the water logging quenching then, withdrawing pattern promptly gets sintered membrane of the present invention.
The antibacterial sintered membrane of making according to raw material proportioning provided by the invention and manufacture craft of active microfiltration, owing to adopted ultra-high molecular weight polyethylene and the best proportioning of carrying silver-colored activated carbon and other auxiliary material, reduce and delay the formation of " biomembrane " effectively, its silver ion has also suppressed breathing and the breeding of bacterium in fiber holes, backwashing time was by original 7 days/time, extend to per 30 days/time or longer, and backwash effect is good.Can be widely used in direct drinking water, industrial wastewater, sanitary wastewater decontamination cycle utilizes again.
