Abstract
The invention relates to a non-formaldehyde glass wool wind pipe plate, wherein its production comprises high-temperature fusing; making fiber; ejecting non-formaldehyde and glass wool adhesive, solidifying, shaping, strengthening the inner adhesive surface; slicing and packing. The non-formaldehyde glass wool adhesive injection method is same as traditional method; the solidify temperature is controlled at 100-300Deg. C; and said adhesive should be heated to 50-70Deg. C before using, and its solid content is higher than 10%.
Description
Technical field:
The invention belongs to the production of mineral wool sheet material, relate to the using method of environment-friendly formaldehyde-free glass wool adhesive.
Background technology:
The bonding agent that uses in the present Chinese mineral wool production of articles is primary raw material with thermosetting phenolic resin, contains a large amount of free formaldehydes, often in use volatilizes formaldehyde easily, and there is serious threat in human health status.
Summary of the invention:
The purpose of this invention is to provide a kind of environment-friendly formaldehyde-free glass wool air conduit, mainly solve the volatilization of free formaldehyde in the existing glass wool air conduit and the effusion problem of microglass fiber.
The using method of the environment-friendly formaldehyde-free glass wool adhesive that the present invention relates to.
For solving the problems of the technologies described above, the present invention is achieved in that
A kind of environment-friendly formaldehyde-free glass wool air conduit is characterized in that: production craft step is:
1. mineral wool feedstock production;
2. high-temperature digestion;
3. become fine;
4. in spraying environment-friendly formaldehyde-free, glass wool adhesive, curing molding and composite glass fiber enhancing, paste
Noodles spare is pasted the outer surface lining of sheet material down;
5. cut back packing warehouse-in;
The injection method of the injection of environment-friendly formaldehyde-free glass wool adhesive and conventional adhesive roughly the same in this production technology, solidification temperature is controlled at: 100～300 ℃, environment-friendly formaldehyde-free glass wool adhesive need give and be heated to 50～70 ℃ in ten minutes before use, solid content 〉=10% of control bonding agent, veneer in composite glass fiber strengthens is pasted the outer surface lining of sheet material.
The problem that environment-friendly formaldehyde-free glass wool air conduit of the present invention solved:
In the market glass wool air conduit exists and contains the problem that free formaldehyde and glass fibre disperse, and uses the back that there is certain harm in health.
Design philosophy of the present invention:
In traditional glass wool air conduit production technology, add special bonding agent, make glass wool air conduit no free formaldehyde volatilization in production, use.
The specific embodiment:
A kind of environment-friendly formaldehyde-free glass wool air conduit is characterized in that: production craft step is:
1. mineral wool feedstock production;
2. high-temperature digestion;
3. become fine;
4. in spraying environment-friendly formaldehyde-free, glass wool adhesive, curing molding and composite glass fiber enhancing, paste
Noodles spare is pasted the outer surface lining of sheet material down;
5. cut back packing warehouse-in;
The injection method of the injection of environment-friendly formaldehyde-free glass wool adhesive and conventional adhesive roughly the same in this production technology, solidification temperature is controlled at: 100～300 ℃, environment-friendly formaldehyde-free glass wool adhesive need give and be heated to 50～70 ℃ in ten minutes before use, solid content 〉=10% of control bonding agent, veneer in composite glass fiber strengthens is pasted the outer surface lining of sheet material.Below be three specific embodiments:
Embodiment one
The injection method of the injection of environment-friendly formaldehyde-free glass wool adhesive and conventional adhesive roughly the same in this production technology, solidification temperature is controlled at: 150～300 ℃, environment-friendly formaldehyde-free glass wool adhesive need give and be heated to 60～70 ℃ in ten minutes before use, solid content 〉=20% of control bonding agent, veneer in composite glass fiber strengthens is pasted the outer surface lining of sheet material.
Embodiment two
The injection method of the injection of environment-friendly formaldehyde-free glass wool adhesive and conventional adhesive roughly the same in this production technology, solidification temperature is controlled at: 100～200 ℃, environment-friendly formaldehyde-free glass wool adhesive need give and be heated to 50～65 ℃ in ten minutes before use, solid content 〉=15% of control bonding agent, veneer in composite glass fiber strengthens is pasted the outer surface lining of sheet material.
Embodiment three
The injection method of the injection of environment-friendly formaldehyde-free glass wool adhesive and conventional adhesive roughly the same in this production technology, solidification temperature is controlled at: 150～250 ℃, environment-friendly formaldehyde-free glass wool adhesive need give and be heated to 60～65 ℃ in ten minutes before use, solid content 〉=30% of control bonding agent, veneer in composite glass fiber strengthens is pasted the outer surface lining of sheet material.
Through the several times test, we propose above three group analysis data, and do experiment in laboratory, relatively back embodiment one result of the test is the most desirable: glass wool air conduit does not have the free formaldehyde volatilization, free from extraneous odour, and the problem of dispersing of glass fibre do not exist yet, and reaches environmental protection requirement, uses the back that human body is not had any harm.
