The self-explosion of tempered glass is inevitable
Self-explosion is the characteristics of tempered glass, inevitably, this is the consensus of the industry. In order to reduce the rate of self-explosion, can only be preferred glass original and secondary heat treatment. Even so, the self-explosion rate of 1 per cent is now the limit and can no longer be reduced. One-thousand-thousand-and-two self-explosion rate has been a high-quality product, which means that an engineering explosion of a few pieces, a dozen pieces is a completely normal phenomenon, we will not be surprised.
But even if a piece of glass is blown, it can be damaged, with severe consequences. Moreover, people outside the profession do not know that this is the normal situation, will be boiling, the media will be everywhere hype, small things big, making it difficult for the curtain wall manufacturers to fight.
Self-explosive glass needs to be replaced, but the cost of replacing far exceeds the glass itself, and it is more difficult and dangerous to replace it in a super-high curtain wall and an alien curtain wall.
Moreover, if a self-explosion occurs, it means that similar events may occur in the future, and when and where are unknown, make people feel insecure. Every time an accident is analyzed, the owner is worried and asks, "Is it still blowing?" "We can only answer unable to answer: "Maybe, not yet qualified." "
(3) Public buildings should use tempered glass with caution
Over the years the facts have now shown that: tempered glass as a "safety glass" for crowded public buildings, there are great safety risks, so that owners and visitors, are in a sense of insecurity. Because I do not know when, I do not know which piece of glass will suddenly blow up, down a burst of glass hail, spread the ground, injured and destroyed.
Therefore, in crowded public buildings, have to choose a single piece of tempered glass, we must be careful to take the necessary safety measures:
1, tempered glass for secondary heat treatment.
2, under the curtain wall set up an isolation zone, do not organize to attract pedestrians and spectators to stay equipment. Indoor wall does not have booths, catering, sales location. Outdoor parking spaces should be removed from the root of the wall, the root of the wall is placed beautifyor or pool.
3, the entrance and exit of the rain shed.
4, the human flow of metal safety net.
5, the film explosion-proof.
