factors affect the vacuum insulating glass quality

Vacuum insulating glass,is turning into the recent fad for building envelope.Architect and creators like this low warm transmittance,high sound acoustic performance,and dainty energy effective glass item for their most current splendid tasks.

Ongoing years,more and more plants put resources into vacuum insulating glass creation and profess to have the most noteworthy quality,but how to pass judgment on the nature of vacuum insulating glass? This posts will examination the variables influencing vacuum insulating glass quality to help you choosing the best VIG items.

Vacuum degree.

The warm protection execution is chosen by the vacuum degree and the low-E coatings.

For most glass production lines, double silver low-E is generally utilized with comparative emissivity, then, at that point, vacuum degree turns into the game changer influencing the last vacuum glass U worth.

Every plant foster their own vacuum glass creation lines while the vacuum degree is unique.

Reproduction in view of Window 7.5 shows VIG U worth is 1.13w/m2.k with 10-2Pa, 0.51W/m2.k with 10-3Pa and 0.44 with 10-4Pa.That's the motivation behind why numerous makers figure out how to deliver VIG with 0.4W/m2.k and some others 0.7W/m2.k,sometimes the vacuum degree is temperamental which cause shaky U worth despite the fact that it's created in a similar line.

HaanGlas produce the vacuum insulating glass at OK high vacuum degree and our 10.3mm VIG with double silver low-E consistent state U worth experimental outcome is 0.47W/M2.K.

Tempered vacuum glass or strengthened glass?

Since its advancement in 1993,vacuum glass creation innovation grew extremely sluggish and had practically all glass were temper vacuum glass,It's restricted by the edge fixing technology.Till now,many worldwide brands actually produce toughen VIG ,which has restricted application .

Tempered vacuum glass has 3-5 times higher strength than typical float VIG.Its mechanical strength ,influence obstruction ,and wind opposition empower the modelers to apply them on more industry,especially glass facade,greenhouse glass, BIPV ,and supplant triple glazing glass utilized in detached houses,etc.

Not the same as others,HaanGlas not just produce completely tempered vacuum protected glass,but likewise has least thickness 6.3mm.To coordinate the huge region glass veneer requirement.

Edge fixing innovation for vacuum insulating glass can be characterized into 2 kinds: Glass powder welds and low temperature metal edge fixing.

Fixing with glass welds is the earliest and most conventional edge fixing technology,it's currently utilized by most vacuum glass producers worldwide.The inconvenience of this innovation is,during fixing process,the bind should be warmed to consolidate 2 pieces glass,which will influence the all around tempered glass to temper again,glass edge strength will diminish by 15-25%.

To solver this problem,many makers will treat the glass in high pressure status,then after sealing,the edge pressure will diminish to ordinary level.

Yet, this will not take care of the issue lopsided glass strength,the lopsided glass strength will cause high glass breakage proportion.

Another edge fixing innovation is low temperature edge sealing.It's fixed by low temperature metal materials,typical makers are Land glass and HaanGlas.After quite a long while market advancement and tasks all around the world,Landvac has demonstrated the top notch of metal edge fixing innovation. Check out tempered vacuum glazing. 

Same as Landvac,HaanGlas vacuum insulating glass is additionally fixed with low temperature metal edge fixing innovation under 250℃，the low temperature keep even glass strength and guarantee low unconstrained breakage proportion.
