Description

A kind of production method of Total heat exchange paper
Technical field
The invention belongs to speciality paper technical field more particularly to a kind of production methods of Total heat exchange paper.
Background technique
Total heat exchange fresh air system is a kind of energy-efficient fresh air system, is widely used in Modern Family, it has also become The new wind devices of mainstream, outdoor air is sent into interior by it after filtering, purification, heat exchange process, is improving indoor air quality On the basis of, reduce the influence to room temperature.Total heat exchange fresh air system at runtime, distinguish by indoor exhaust wind and outdoor fresh air Orthogonal thereto fork mode flows through full heat converter core, since two sidewind of splitter plate is there is the temperature difference and vapor partial pressure are poor, Heat and mass phenomenon is presented in two strands of air-flows when passing through demarcation plate, fresh air effectively obtains the enthalpy in air draft, causes Total heat exchange Process, to achieve the purpose that energy-saving scavenging.
Core component --- the material of full heat converter core based on above-mentioned working principle, in Total heat exchange fresh air system Not only need to carry out fresh air and air draft (especially there is high barrier to pernicious gases such as carbon dioxide, formaldehyde) effectively every From to guarantee that fresh air is unaffected；And need to have high-permeability energy for the steam in air, effectively to recycle Latent heat in air draft；Should also have good heat transfer property simultaneously, effectively to recycle the sensible heat in air draft.Full heat converter core The performance of material directly affects the performance of total-heat exchanger, to influence the Total heat exchange enthalpy of entire Total heat exchange fresh air system Efficiency.It is complete for making therefore, it is necessary to develop a kind of material with high moisture-inhibiting degree, low air permeability and good heat transfer capacity The core of heat exchanger, to improve the enthalpy efficiency of the Total heat exchange of New-air purifying system.
Summary of the invention
Aiming at the problem that the purpose of the present invention is proposed in the above-mentioned background technique, a kind of production of Total heat exchange paper is provided Method.
The technical solution used in the present invention is: a kind of production method of Total heat exchange paper, which is characterized in that including following Step:
1) body paper is manufactured paper with pulp: using vegetable-fibre slurry as raw material, opposite bone dry fiber is added in vegetable-fibre slurry Amount is the wet strength agent of 0.2-1.5%, is manufactured paper with pulp to obtain body paper as medium using water；
2) it obtains mixed glue solution: natural polymers and water-insoluble antimildew and antibacterial agent is mixed evenly to obtain 2.0-10.0g/m2Mixed glue solution, natural polymers be starch, sodium carboxymethylcellulose, guar gum, polyethylene pyrrole At least one of pyrrolidone, chitosan, soya casein, gelatin；
3) it applies mixed glue solution: applying mixed glue solution on body paper, obtain Total heat exchange paper；
The sequence of step 1) and step 2) is in no particular order.
Preferably, vegetable-fibre slurry is the mixed slurry of softwood pulp or softwood pulp and hardwood pulp, mashing Degree is 20-60 ° of SR.
Preferably, wet strength agent is urea formaldehyde resin, polyamine epichlorohydrin resin, melamine resin and gathers At least one of aziridine.
Preferably, adding opposite dry paper fiber in step 1) in vegetable-fibre slurry is the wet strong of 0.2-1.5% While agent, the drying strengthening agent that opposite dry paper fiber is 0.2-2.0% is added.
Preferably, drying strengthening agent be natural plant gum class, polyacrylamide high molecular polymer, in cationic starch at least It is a kind of.
Preferably, water-insoluble antimildew and antibacterial agent is zinc oxide, chitin, copper 8-hydroxyquinolinate, thiabendazole, glutaraldehyde cross-linking At least one of agent.
Preferably, being manufactured paper with pulp using cylinder or long mesh paper making machine to raw material in step 1).
Preferably, the mode that step 3) applies mixed glue solution on body paper is dipping, one side coating, double spread, spray One of apply.
Preferably, Total heat exchange paper 23 DEG C of temperature, humidity 50%RH detection environment under, air permeability≤1 μm/Pa S, moisture permeability >=650g/m2·24h。
Total heat exchange paper of the present invention has the mechanism of moisturizing water vapour permeability: transmitting row of the stream molecule in polymeric membrane To follow " dissolution-diffusion " mechanism.The natural polymers that the present invention chooses include natural macromolecule amylose quasi polymer With natural polymer proteinaceous polymers, these polymer belong to the strong high molecular material of polarity, contain a large amount of hydrophilic group Group's (such as hydroxyl, amino) has very strong affinity interaction to stream molecule, these hydrophilic radicals and stream molecule are to form hydrogen The form of key interacts, to reach moisturizing moisture-inhibiting effect.On the other hand, the natural polymers of selection belong to part Crystalline polymers material, the crystal region both formed with highly polar Interaction of substituents on molecular structure, while also having one Fixed noncrystalline domain.When indoor humidity is smaller in fresh air system, hydrophilic radical is with hydrogen bond formation part " capture " extraneous fresh air Stream molecule plays the left and right of moisturizing；When indoor humidity is larger, high molecular noncrystalline segment can pass through the side of warm-up movement Formula forms the hole of moment between strand, and inside and outside applied layer water vapour pressure difference promotion, the water of " capture " steams Vapour molecule will be diffused into the other side from the high side of vapour pressure along the gap of strand, achievees the purpose that moisture-inhibiting, prevents from condensing.
The present invention has the advantage that and good effect: the Total heat exchange paper produced by adopting the above technical scheme, has high saturating Humidity, low air permeability and good heat transfer property, suitable for the production of fresh air system full heat converter core, using the full heat The full heat converter core of paper production is exchanged compared with traditional core, for the steam permeability with higher in air, energy Latent heat and sensible heat in enough effectively recycling air drafts, are imitated using the fresh air system of full heat converter core enthalpy with higher Rate；By the way that wet strength agent and drying strengthening agent is added, so that Total heat exchange paper dry and wet tensile strength with higher, so that full heat is handed over Paper is changed with longer service life.
