Abstract
The invention discloses a kind of preparation methods of antibacterial hollow-fibre membrane.The present invention carries out as steps described below：1. active carbon loading silver fiber filament to be prepared to the woven hollow fiber pipe of active carbon loading silver fiber by existing knitting skill, silver-colored carbon woven tube is referred to as carried；2. carrying silver-colored carbon woven tube to gained using ultrafiltration membrane film forming feed liquid carries out surface coating, coating invasive depth carries silver-colored carbon for 2/3 and weaves thickness of pipe wall, is finally immersed in solidification bath water and carries out solidified forming.Gained hollow-fibre membrane of the invention is integrated ultra-filtration and separation and three controls for acting through spinning membrane system technique and membrane structure of activated carbon adsorption and Ag-carried antibacterial, the technological process of Water treatment is effectively shortened, avoids issuable all kinds of problems in each link matching process.
Description
Technical field
The present invention relates to water treatment product technical fields, more specifically, are related to a kind of suitable for drinking water treatment
The preparation method of hollow-fibre membrane with antibacterial functions.
Background technology
With the development of household water filter, required for its comprehensive function higher and higher.Household water filter usually requires to pass through
The ultrafiltration membrance filter removal impurity such as thalline and colloid are crossed, improve mouthfeel using activated carbon, sterilized using ultraviolet light etc. etc.,
Middle activated carbon and ultraviolet disinfection can also use active carbon loading silver to substitute.The integrated degree of this obvious process is relatively low, and flows
Journey length causes to occur water body and leaks or the problem of other influences water quality safety when being then susceptible to because each link be connected the problem of.
The content of the invention
The technical problems to be solved by the invention are to overcome the deficiencies in the prior art, and it is hollow to provide a kind of antibacterial
The preparation method of tunica fibrosa.
A kind of preparation method of antibacterial hollow-fibre membrane of the present invention, carries out as steps described below：It is 1. active carbon loading silver is fine
Dimension long filament prepares the woven hollow fiber pipe of active carbon loading silver fiber by existing knitting skill, referred to as carries silver-colored carbon woven tube；
2. carrying silver-colored carbon woven tube to gained using ultrafiltration membrane film forming feed liquid carries out surface coating, coating invasive depth carries for 2/3
Silver-colored carbon weaves thickness of pipe wall, is finally immersed in solidification bath water and carries out solidified forming.
The ultrafiltration membrane film forming feed liquid is conventional polymer film forming feed liquid；The control of the coating invasive depth relies on ultrafiltration
The air bath length that film film forming viscosity of sludge and coating impregnation process are passed through.Ultrafiltration membrane film forming viscosity of sludge rise, then coat
Invasive depth is shallower, and the air bath length of warp is more long, and the depth infiltrated is deeper.
Compared with prior art, the beneficial effects of the invention are as follows：
Compared with prior art, present invention gained hollow-fibre membrane is by ultra-filtration and separation and activated carbon adsorption and Ag-carried antibacterial three
It is a to act through spinning membrane system technique and the control of membrane structure is integrated, the technological process of Water treatment is effectively shortened,
Avoid issuable all kinds of problems in each link matching process.
Specific embodiment
The present invention is described in further detail below in conjunction with specific embodiment.It is it should be appreciated that described herein specific
Embodiment is only used to explain the present invention, is not intended to limit the present invention.
Embodiment 1
By active carbon loading silver fiber filament incoming fiber braider, it is spun into the silver-colored carbon of load using existing knitting skill and weaves
Pipe takes out the load silver charcoal woven tube spun, and the load silver charcoal woven tube spun is accessed wet spinning production line；Utilize existing volume
Periosteum technology of preparing is knitted, the ultrafiltration film forming feed liquid that a layered material fluid viscosity 4000mPas is coated on its surface is squeezed out through spinneret, is applied
The woven tube covered immerses water coagulating tank after the air bath of one section of 30cm, and after after silk washing is received in drawing-off row antibacterial is made
Hollow-fibre membrane, the infiltration binder course formed between gained film surface functional layer and the silver-colored charcoal woven tube of load about carry silver-colored charcoal woven tube
The 1/3 of wall thickness.
The control of the coating invasive depth relies on ultrafiltration membrane film forming viscosity of sludge and coats the sky that impregnation process is passed through
Gas bath length.Ultrafiltration membrane film forming viscosity of sludge rise, then coat that invasive depth is shallower, the air bath length of warp is more long, infiltrates
Depth is deeper.For the occasion that water water quality safety is poor, then need coating invasive depth control carrying silver-colored carbon woven tube horizontal stroke
Section wall thickness at 1/3rd or so, reserves 2/3rds or so and is used as degerming functions layers from outside to inside；For water water quality
The preferable occasion of safety, then can reduce reserved degerming functions layer thickness.
The above is only the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
