Hollow glass is currently held by butyl rubber views and Suggestions

As the first hollow glass industry professionals to join one of those who , for now hollow glass production technology and manufacturing materials to make the following personal opinion :

1 , hollow glass production process should be double sealed mainly because the double sealed insulating glass can be in any need to use the hollow glass industry applications , although there are many industry production process exists, but there is always this and that these processes defects , although these preachers craftsmanship unlimited exaggerate them to a function , but as a few basic requirements for insulating glass such as air tightness , resistance to ultraviolet radiation, high temperature and humidity , solvent resistance, wind resistance , and two glass and aluminum structural strength is needed quite perfect insulating glass production process to complete. I personally inspected several widely used in Europe and America countries and regions of insulating glass , double sealing process dominates the mainstream market , other processes exist only as a supplement ; although double sealed and has a relatively complex process , but because with the use of a wide range of reliable and stable the quality , its advantages can not be negated by certain one-sidedness ;

2 , in the industry on the application of insulating glass sealing material has a lot of debate , I believe that many of them with obvious utilitarian arguments , who did what products to exaggerate their superiority of one or a few products , while ignoring the as a complete insulating glass production needs, such as strip -type process only emphasizes its tightness ( the raw material of butyl rubber and polyisobutylene, its water vapor transmission rate is very low ) . Can not ignore the temperature, solvent , and the shortcomings of poor creep resistance ; silicone rubber only emphasize its resistance to UV and anti-aging properties has ignored its high vapor permeability and migration out of the silicone oil will dissolve as the first a butyl rubber seal and destroy the entire sealing system , although some promotional nanomaterials can be modified to increase air tightness of silicone rubber , but according to the survey data using nano material modified sealant now only in the laboratory , only is a relatively distant fantasy ;

3 , so the analysis of the advantages and disadvantages of various materials is not difficult to draw the following conclusions : For less demanding hollow glass mosaic decoration for indoor use because of climatic conditions are not in contact with the outside world with tape -type insulating glass production process is preferred ; For hidden frame wall hollow glass on account of security , requiring high structural strength and resistance to UV aging resistance , the use of silicone - butyl rubber series double sealing process is exactly the same choice. For other broader field of use as insulating glass polysulfide - butyl series double sealing process has a high air tightness , solvent resistance, high temperature resistance , creep resistance , superior performance , in the present has a very important position.

4 , it is recommended : As high-tech insulating glass production is not only labor- intensive industries , on the basis of the existing equipment with double sealed manufacturers buy more pressing machine ; strip style butyl rubber manufacturers buy machine then you can produce a variety of needs hollow glass , and the province of the province , and the simple is simple , and the complex is also complex , in short , the ability to adapt to the market also increased . Note: The imported equipment more expensive .
