1st, is the ultra white tempered glass why low from the knock rating?
Low-valence iron glass, because its iron content is lower than the simple glass far, therefore looks like glittering and translucent carving, therefore also calls the ultra white glass.Floats the law glass relatively ordinary, ultra white glass in production process in order to remove iron, a many magnetically separated ore working procedure, has also blown out in the ablution iron process the nickel, causes in the ultra white glass the nickel pyrite content to be extremely low, but the nickel pyrite is precisely the tempered glass from the basic reason which explodes, therefore ultra white armored glass extremely is also low from the knock rating.According to the south Bolivia group multitudinous project case service condition statistics, the ultra white tempered glass is approximately 1/10000 (ordinary tempered glass is higher than 3/1000 from the knock rating from knock rating).
2nd, what way also has to reduce the tempered glass from the knock rating?
The isotropic processing may reduce the tempered glass from the knock rating, the tempered glass is called " the isotropic tempered glass " after homogenization processing.The isotropic processing is puts in the tempered glass the isotropic stove internal heating to elevate temperature to certain temperature, after heat preservation, temperature decrease process.Includes the nickel pyrite or other impurity tempered glass in this process can fire, therefore the isotropic processing is also called “fires processing”.Ordinary isotropic tempered glass from knock rating approximately in 1/1000.
3rd, the ultra white tempered glass and the isotropic tempered glass price comparison
at present south Bolivia and the domestic other factories have been possible the mass production ultra white glass.Changes the ultra white tempered glass the isotropic tempered glass, the increase expense is limited, but may obviously reduce from the knock rating, reduced the steel from to explode enormously crashes offends somebody, the wound accident, as well as in the construction use process the maintenance cost, specially the extra-high building glass from exploded after the replacement expense.Compares says, uses the ultra white tempered glass comprehensive price scaled height of burst.
