Borosilicate Heat-resistant glass3.3(BG3.3)
Product Introduction
Borosilicate glass 3.3, also known as "bulletproof borosilicate glass," is a type of strong and durable glass that has been widely used in the manufacturing of bullet-resistant windows for many years. It is made from boron silicate which has a very high melting point and can withstand extremely high temperatures without breaking or shattering. This makes it ideal for use in applications that require protection from bullets or other projectiles, such as security guards' booths, military installations, banks and airports.
The most common form of bulletproof borosilicate glass is Grade 3.3 (sometimes referred to as BORO33), which has an impressive resistance to impact damage compared to its non-bulletproof counterparts. This grade of borosilicate was developed specifically with ballistic performance in mind and meets the requirements set out by various international standards - including EN 1063 (the European Standard) and UL 752 (the American Standard). The safety rating achieved by this product reflects its ability to stop different levels of ammunition travelling at different speeds without breakage or significant deformation; even when multiple rounds are fired consecutively at close range. As bulletproof glass, borosilicate 4.0 glass also has a remarkable characteristic of high transmittance. In this way, when used as bulletproof glass, you can clearly observe the external things through the glass.

- Q:There is a clear coat of build up o my glasses lense. Not sure what it is but I can feel it when I scrape it with my finger. Looks like something froze on it haha best way to describe it I guess ha. Was thinking acetone but dont want to mess up the lense. Any ideas?
- Have you ever heard of an ammonia based product called "Windex" ? Other general purpose glass cleaners will also work.
- Q:I would like to build my own, customized aquarium and I have recently found out that float glass would be the best glass to use for it.I want the tank to be pretty long, considering i am turning it into a vivarium for my turtle.I need to know how much it will cost me to buy the sheets of float glass? or If I can just use regular glass for this instead?I am looking for something inexpensive, but with the quality also.thanks for the help :)
- Either glass is going to be very expensive. Check with your local hardware store.
- Q:i have an important eco friendly house project 2 do so i need some answers!!!! if u could also post some sites that wld b gr8!!
- I okorder Go to his projects section and take a look as he has many links within his site and external as well. The basic principles of passive solar can be applied anywhere. If you are looking for construction plans and measured drawings- don't. There is too much variation in the windows themselves. You have to have some basic construction skills and some basic design sense to make it really work because those cariations lead to gaps that need filling in, and a means of supporting things. One hint though. If you make a small greenhouse, longer in the east/west direction is best with a low ceiling/roofline, and no narrower than about 8 feet. For heat storage you can use rock, but you will likely have better luck with 55 gallon food grade poly barrels filled with saturated salt water. Start with a dark colored plastic and paint them flat black. Also only fill them about 3/4 full. They will be heavy so place them in their final spot first. Insulate the space, 1 inch foam has respectable performance, add a vapor barrier, and add aluminum foil as radient barrier on the walls as the very inside layer to reflect light to the back side of your heat storage. On the roof, put the foil between the foam and the roof deck. It does work very well. Even in subzero farenheit temps. As long as you have sunlight, it will stay above freezing, otherwise a small 300 watt heater is adequate with 2 60 watt incandescent bulbs to keep it above freezing on the very coldest days.
- Q:how to clean scum build up on glass shower doors?
- I went to Dollar General and bought a spray bottle of Works Shower and Tub Cleaner (do not confuse this with THE WORKS SHOWER AND TUB) totally different product it cost me a dollar and is the best stuff I have found for soap scum just spray it on wait a few minutes and wipe it right off. It saves me so much time, money, and hassle.
- Q:Glass bottom margin of the final decoration surface is less than 500 hollow glass how to install?
- Your insulating glass can not be regarded as a safe insulating glass, and if the building needs to comply with the "Building Safety Glass Management Regulations", such glass can not be used. If there is no strict requirements, from the perspective of building safety, only the safety glass (ie, tempered glass) one toward the outside, to prevent the outer film damage caused by serious harm to outsiders.
- Q:Why does the endothermic glass be cool in winter and cool
- Can reduce the amount of solar heat entering the room through the glass, which is achieved by increasing the reflection of the sun (not necessarily the reflection of the visible light) and the heat absorption of the glass. The general color film mainly functions by increasing the absorption of sunlight , These colors can absorb the sun on the glass, thereby reducing the solar energy into the room. This film is only an auxiliary effect compared to our building insulation glass film. Building glass film covered with a layer of metal, this metal film, can increase the glass of light reflection and light absorption, which greatly blocked the solar heat in the glass window, the same reason, in the winter can make high temperature indoor heat is not out , To ensure comfortable indoor temperature.
- Q:Theoretically, if glass dropped and the stress incurred was just less than that required to shatter it, would the next drop, no matter how small, break the glass? If not can it continue to take infinitely more stress damage as long as they each individually do not surpass its stress limit, even though their sum does?Note: I am asking this with the real life application of the glass backs of iPhones in mind
- You should investigate what the amount of energy is required to cause a defect either in manufacturing or physical damage to initiate and propagate a crack. The defect may be improper heat treatment, a foreign inclusion, a void in the glass matrix, a nick or scratch in the casting process or in handling in the production line, for example. Each cycle of dropping could potentially have enough energy to further propagate the crack until full fracture is achieved, You may want to investigate fracture mechanics. .
- Q:In our house, my bf and I have a half wall dividing the family room from the breakfast nook. We'd like to put a partial glass block wall on the half wall to create a place to divide the wall when we paint. What materials do we need, and can anyone point us to a good online source with steps for the process?
- Most okorder . You will need the glass block, the glass block mortar, spacers (make sure you buy the correct spacers. Glass block comes in two thicknesses and there is a specific spacer for each thickness), anchors, and reinforcement strips. You won't have to tie in to your ceiling joices. Just make sure you fully anchor to the wood in your half wall.
- Q:How does glass and steel affect modern architecture?
- Two main applications: glass curtain wall and steel structure
- Q:I have been laid off my job of 26 years doing exactly this. I would like to look into teaching at a community college passing my skills onto others. Any advice?How much do you think I could expect to get paid?Thanks in advance!
- For quickest assessment of opportunities, check out your future competitors. Find shops that now teach stained glass classes. See their brochures, ads and prices. Take from the best from several...then advertise around town using a simple 8 1/2 X 11 inch flyer placed everywhere...supermarkets, library, in free paper racks (stuff the copy into the Weekly) and on windshields. I went to a class a few years ago, and loved the course work. It was once weekly for 6 weeks. If you need help with ideas on advertisements that pop, go to Barnes & Noble and browse the slick AD trade Mags. Brevity and flair with harsh color contrast will likely click. Start a stained glass info-blog. Write an article about yourself, and this will be picked up by a Features Editor who realizes that the source for endless living beauty is found in stained glass. If you need forever-fuel to propel you...visit Florence, Italy. You'll probably stay there. Good luck!
