Summary And Solution Of The Problem Of Aerogel Insulation Blanket Powder Dropping

Questions about aerogels

1. Do anyone know how to make the aerogel fiber blanket no powder? How to deal with it? What additives or glue should be added? Thank you.

2. If you use a reactive organic adhesive, then do you know which organic adhesives are suitable?

Aerogel problem solution

We all know that the basic process of the aerogel insulation blanket is that the aerogel substrate is injected into the insulation blanket to achieve the effect of thermal insulation. The surface of the insulated blanket must also be exposed to the gels, and this is also related to your ratio and process, and it does not do well. Although the aerogel is very light, and the adhesion is very strong. But if the process is not considerate, the powder phenomenon will also appear. So how to improve it?

In fact, if you want to attach a layer of aluminum film to it, you can perfectly solve this problem. We need to pay attention to what adhesion is good. This kind of adhesive can not be excellent, and it will not appear to harden after adhesion. It is also a standard for choosing glue to ensure that the flexibility of blanket is not affected.

In addition, making use of other cloth, paper and board materials and air aerogel based materials to intercalate composites to create lightweight super insulation composites is also possible. Here is the two processing technology.

Joda proposed a method for producing off powder sandwich structure super insulation gel composite laminated, bonded, specific steps are as follows:

(1) the aerogel based materials are rolled to remove the easily shedding powders or particles.

(2) the surface of aerogel based material is evenly coated with adhesive on the surface of step (1), and the inorganic fireproof cloth is evenly and smoothly adhered to the outer surface of aerogel based material, or the binder is coated on the inorganic fireproof cloth, and the adhesive is evenly and smoothly adhered to the outer surface of aerogel base material.

(3) after curing the sandwich composite material (2), we can get nano porous aerogel sandwich structure lightweight super insulation composite material without powder and beautiful appearance.

The aerogel based material in step (1) is any of the blanket, blanket or plate composites with aerogels as thermal insulation substrates.

The binder in step 2 is any kind of silicate, phosphate, oxide, borate inorganic adhesive, or any kind of resin or rubber organic adhesive.

Step (2) inorganic fireproof cloth of the glass fiber cloth, Teflon as fire retardant fireproof cloth or asbestos base in a fireproof cloth.

Method for the production process involves Joda widely and easily available raw materials, low cost, lightweight super insulation aerogel sandwich structure made of composite material has the advantages off powder, appearance, simple process, safety, environmental protection, long service life, is of great significance for the field of ship, vehicle, aircraft and industrial pipeline the building wall insulation, etc..

The above is the solution to the problem of falling off the powder of aerogel insulation blanket, and I hope it will help you in the process of aerogel insulation material production.
