Choose the details of tempered glass

 The use of tempered glass with high toughness, bending resistance and high safety performance is becoming more and more common in home decoration. However, as a glass product, tempered glass can have a lot of precautions.

    Here are some details about the use of tempered glass.

1. Pay attention to the corners of the tempered glass. If the corners of the tempered glass are damaged, the risk of self-explosion of the glass will increase exponentially. Since the stress points of the tempered glass are all concentrated at the corners, the protection of the corners is particularly important, and care must be taken when the tempered glass with broken corners cannot be handled;

2, to avoid tempered glass for a long time under pressure for indoor beauty, many families will choose to use tempered glass as a tabletop table, coffee table, the general tempered glass withstand pressure between 70mpa to 100mpa, this pressure multiplied by the force area of ​​the glass It is the maximum pressure it can withstand. Converted into item quality = (pressure * area) / 10, if not necessary, do not place heavy objects on the tempered glass table for a long time, to avoid the pressure value reaching the critical point and causing the tempered glass supplier to break;

3, to avoid uneven heat and cold, if in extreme conditions, apply high temperature and low temperature on both ends of a piece of glass, then this glass will be self-explosive 90%, such as pouring cold water on the incandescent lamp, incandescent lamp The glass will break. Although this situation will be small for tempered glass, it is not afraid of 10,000;

4. Keep away from acid and alkali materials. Avoid contact with tempered glass with alkaline substances such as sodium hydroxide and *(HF). The glass is essentially silica (SiO2), which will chemically react with the above substances;

5. It is forbidden to use sharp and hard objects to strike the corners of the glass. Since the stress points of the tempered glass are concentrated at the corners, once the corners are broken, the chance of rupture of the tempered glass will increase, so for the safety of the home, do not use sharp edges. Hard objects hit the corners of the tempered glass.

    In addition to the quality of tempered glass, the rigor of installation and use is also an important factor related to safety.

1. Customized doors and windows, tempered glass cutting If the tempered glass door does not meet the installation size, it is very troublesome to rework, so it is necessary to be accurate when starting the measurement. The measurement of tempered glass mainly includes two aspects of the width and height of the glass plate. When measuring the width of the glass plate, measurements were made at the bottom, middle, and top, respectively, and the minimum size was selected as the width of the cut. If the data obtained from the top, middle and bottom are identical, then 3-5 mm is reduced in the measured dimensions as the cutting width of the glass. Similarly, the height of the glass plate should include the installation location for inserting the upper and lower rails, so it is generally taken to cut less than 3-5 mm of the measured data.

2. Treatment and installation of tempered glass

After the glass plate is cut by size, it is usually necessary to chamfer the four corners, and the fine grinding wheel is generally used for slow grinding operation. Then the fixed bottom bracket is fixed, and the aluminum alloy door and window are fixed by the aluminum alloy frame, and are fixed on the frame with the aluminum angle. Use a glass suction cup to first pass the glass plate to the west and place the glass in place. Insert the upper part of the glass into the limit groove of the door frame, and then place the lower part of the glass plate in the opposite seam of the bottom cover.

3, glue injection, door and window molding, windproof and waterproof glass plate is fixed thick, at the top of the limit groove and the bottom of the fixed position, as well as the glass plate and the frame column of the seam is glued and sealed. Use a plastic sheet to flatten the glue on both sides of the glass and wipe off the residue. Be careful when wiping the remnants. Try not to use sharp objects such as blades. After the height of the door is determined, the glass strips are inserted into the gaps on both sides of the crosspiece, and small wooden strips are inserted from both sides, tapping and stabilizing, and injecting glass glue into the gap formed between the small wooden strips, the door leaf glass and the crosspiece, The residue is treated as above. Tempered glass belongs to safety glass and is widely used in places with high mechanical strength and safety requirements. Everyone must pay attention to detail and safety when using it.
