Embodiment 1-8

[0104] Raw materials and the mass ratio of each substance are shown in the table below:

[0105]

[0106]

[0107] The preparation process is as follows:

[0108] 2. The manufacturing process of the total heat exchange heat recovery membrane (number 0# in this embodiment) of this embodiment:

[0109] (1.1) Grinding of seed crystal materials: SiO2 / Al2O3 / Na2O / CDA materials are mixed according to the ratio described in Example 1 and ground into fine powder on a grinder, and particles with a particle diameter of ≤7 μm are screened out with a dust sieve.

[0110] (1.2) Dilute spray paint: dilute and mix tetrahydrofuran solvent and SiO2 / Al2O3 / Na2O / CDA mixed powder in a ratio of 50:1, and stir evenly.

[0111] (1.3) Spraying seed crystals: Install natural cellulose film (original pulp paper film) on the spraying line of the special pervaporation production line, spray zeolite powder and tetrahydrofuran dry solvent on both sides of the natural cellulose film, and the coating th...

Embodiment 9

[0117] see Figure 8 , this embodiment is called 32# film in the design process,

[0118] (1) 32# membrane solution ingredients: C2H6O / CH4O / LiCl / H2O / SiO2 ratio is 7 / 9 / 98 / 3 / 888. Pay attention to the 32# membrane solution ingredients and mixing, methanol and ethanol have alcohol smell, And it is flammable, pay attention to the protection of fire prevention and alcohol poisoning.

[0119] (2) Immersion: in the immersion section of the 32# membrane production line. Install the cellulose substrate on the roll paper stand, and pass it through the guide rollers and the solution tank, and roll the other end of the original pulp paper on the roll machine; install the prepared 32# membrane solution in the solution tank. Start the motor of the winder. Pay attention to adjust the immersion time within 5-20 minutes according to the ambient temperature, so as to ensure that the original pulp paper is soaked. Note: The operator should not spend more than 60 minutes between processing in ...

Abstract

The invention belongs to the technical field of energy recycle, particularly relates to a full-heat-exchange heat recycle membrane and a manufacturing process thereof, overcomes the defects such as high cost, low heat exchange efficiency and poor strength in prior heat recycle membranes, and develops a full-heat-exchange heat recycle membrane using novel materials and a novel technology, this membrane being high in heat recycle efficiency, good in strength, flame-retardant and capable of degrading molds. The full-heat-exchange heat recycle membrane comprises a cellulose matrix and an absorbent layer; the absorbent layer is positioned on the cellulose matrix and is made by mixing the following materials according to a ratio of 1:5-100: a water molecular absorbent and a solvent. The membrane of the invention is obtained by applying the absorbent layer to the cellulose matrix and drying; the membrane is high heat recycle efficiency, good in strength, flame-retardant and antibacterial ad is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of energy recovery, and in particular relates to a total heat exchange heat recovery film and its manufacturing technology and equipment. Background technique [0002] With the development of industry and the serious pollution of the living environment, air conditioners have become popular all over the world. Air conditioning and fresh air have become necessary requirements for human life. The introduction of fresh air leads to the loss of one-third of the air conditioning energy. An important energy-saving means of using air conditioners. Energy conservation, emission reduction and air pollution control have become important topics of the 13th Five-Year Plan. Air energy recovery has long been popularized in developed countries, but China is still in its infancy. In order to accelerate the development of air energy recovery devices in China, the country has included the application of air energy recovery de...
