Manufacturing process of ultra-large low-temperature liquid-filled insulating layer

[0023] Example 1:

[0024] The present invention provides the following technical solution: an ultra-large cryogenic hydraulic irrigation insulating process, including the following steps:

[0025] A, first cleaning the surface of the tank;

[0026] B, then sprayed in the surface of the tank;

[0027] C, sprayed the first layer of foam;

[0028] D, after the first layer of glass is installed on the first layer foam;

[0029] E, then spray the second layer of foam outside the glass layer;

[0030] F, after the air gel / rock cotton is installed;

[0031] G, spray the third layer of foam;

[0032] H, install the second floor glass network outside the third foam;

[0033] I, spray the fourth layer of foam outside the outer glass network;

[0034] J, finally sprayed polyurea outside the fourth layer of foam to complete the insulating layer.

[0035] In the present embodiment, the first layer of foam, the second layer foam, the third layer foam, the fourth layer foam content component a
