The technical process of complex reverse osmosis membrane is described in United States Patent (USP) US4277344A, i.e., is first coated in polysulfones
The micropore counterdie formed on polyester non-woven fabric by phase inversion, is immersed in diamines or polyamines aqueous solution, then drenched by wind,
The methods of roll-in shows extra amine aqueous solution except striping, then is immersed in the chloride compounds containing two or more acid chloride groups
Interface polymerization reaction occurs with acyl chlorides in organic non-polar solution, to form the fine and close polyamides with separation function on surface
Amine ultra-thin separating layer after film forming, then carries out heat cure, washing and post-processing, prepares complex reverse osmosis membrane required for our.
In traditional reverse osmosis membrane preparation process, the heat treatment of complex reverse osmosis membrane composite membrane-forming can be inevitable
So that causing basement membrane hole to collapse, shrink due to the loss of hydrone in basement membrane hole, the saturating of entire complex reverse osmosis membrane is seriously reduced
Aqueous energy.In order to overcome these drawbacks, people inevitably need to adjust combination process, but can not still avoid, make completely
The process that must be produced is complicated, increases composite cost.
Utility model content
In view of the problems of the existing technology, the utility model proposes a kind of complex reverse osmosis membrane preparation facilities, compound
A set of back side dip coating apparatus is added in reverse osmosis membrane heating process, to protect the pore structure of basement membrane in complex reverse osmosis membrane compound
It will not shrink and collapse because of dehydration during reverse osmosis membrane is heating and drying.
The utility model solves the technical solution of the above technical problem: a kind of complex reverse osmosis membrane preparation facilities, including from
Preparation facilities starting point is disposed with support deflector roll, leaching amine device, surface drying device, leaching acyl chlorides device, baking oven, back side dip-coating dress
It sets, the support deflector roll is equipped between each device to support complex reverse osmosis membrane；The back side dip coating apparatus by coated,
Material fluid bath and four support deflector roll compositions, the material fluid bath are higher boiling water equipped with certain density protection liquid, protection liquid is prepared
The aqueous solution of dissolubility organic molecule；Complex reverse osmosis membrane enters the leaching amine device by the support deflector roll, after impregnating amine liquid,
Using the surface drying device, into the leaching acyl chlorides device, enter baking oven using support deflector roll, the baking oven lower part is equipped with
Back side dip coating apparatus.
The leaching amine device is made of leaching amine bottom roller and amine slot, and the leaching acyl chlorides device is by acyl chlorides slot and leaching acyl chlorides bottom roller group
At.
The coated is soft foamed material resistant to high temperature, and the coated rotation direction is opposite with film trend.
During complex reverse osmosis membrane walk cloth, complex reverse osmosis membrane pass through amine and acyl chlorides interface polymerization reaction, tentatively at
Film, during forming a film into curing oven, coated speckles with the back side that a large amount of protection liquid enters complex reverse osmosis membrane.The heating phase
Between protect the basement membrane fenestra of complex reverse osmosis membrane to occur structure destruction because of dehydration, while will not influence again aramid layer plus
The evaporation of heat cure and residual solvent.
The utility model has the beneficial effects that the utility model adds a set of back side leaching in complex reverse osmosis membrane heating process
Coating device, in the aqueous solution of the certain density higher boiling organic molecule of the backside coating of complex reverse osmosis membrane, complex reverse osmosis membrane
During the entire process of being heating and curing, higher boiling organic molecule can be stayed in always in complex reverse osmosis membrane basement membrane hole, be protected compound
The pore structure of basement membrane will not shrink and collapse because of dehydration during complex reverse osmosis membrane is heating and drying in reverse osmosis membrane, according to
The complex reverse osmosis membrane of this preparation has high-throughput and high rejection.
