How to use and stock the mirrors ?
2006-06-22
1.Keep the silver mirror storage area as dry as possible, avoid rain and moisture contact, do not store in the open air, keep away from aci,d alkaline liquid or gas, and do not store it with other chemicals.
2.Avoid excessive use of cutting oil, which must be cleaned within 1 day after cutting. Otherwise it is easy to corrode the edges.
3.The edging speed should not be too fast, the slanting edge should be less than 2m/min, the cooling water should be enough, dry grinding is strictly forbidden, the edging is too fast, the lens is heate,d and the lacquer layer and the silver layer are easily peeled off.
4.Cooling water, polishing water and chemicals should be used when grinding. It should be replaced with the change of PH. Generally, the PH value is between 7-8. The water for the processor is preferably clean tap water to keep the water clean.
5.After edging, it should be cleaned in time, dried and stored. When packing, the operator should wear gloves to avoid the sweat on the hand to contaminate the edge of the mirror. The septum rubber should be made of sulfur-free material, and the nylon rope should be kept clean and neutral.
6.The edging machine and the washing machine should be cleaned regularly, and the condition of the grinding wheel should be checked frequently. If the wear is serious, it should be replaced immediately.
7.If the silver mirror needs to be edge,d be sure to be clean and clean. The PH value of the glue is neutral, otherwise the edges will be dirt, polishing powder, nitrogenous substances, sulfides, and bacteria.

Do you know the process of flat glass ?
2007-05-01
The main raw materials of flat glass are: silica sand (sandstone), soda ash, feldspar, dolomite, limestone, thenardite.
Process:
1. Raw material crushing: The above raw materials are broken into powder.
2. Weighing: Weigh a certain amount of various powders according to the planned ingredients.
3. Mixing: Mix and stir the weighed powder into a batch material (coloring glass is added with coloring agent at the same time).
4. Melting: The batch material is sent to a glass melting furnace and melted into a glass liquid at 1700 degrees.
5. Molding: The glass liquid is sent into a tin bath (floating method), a flat drawing machine (later method), a calendering machine (calendering metho,d adding a wire into a wire glass), and forming into a flat glass.
6. Annealing: The formed glass products are sent to an annealing kiln for annealing to balance the stress and prevent self-breaking.
7, inspection, packaging.

Do u know these knowledges about tempered glass ?
2007-08-20
1. Only tempered glass with a width greater than 8 times thickness can be drilled.
2. For tempered glass with a thickness not exceeding 12 mm, the distance from the edge of the hole to the edge of the glass shall not be less than 1.5 times the thickness of the glass; for tempered glass with a thickness exceeding 12 mm, the distance from the edge of the hole to the edge of the glass shall not be less than 2 times the thickness of the glass.
3. The diameter of the circular hole on the tempered glass should be at least 1.6 mm larger than the thickness of the glass; the diameter of the circular hole should be less than 1/3 of the width; the radius of the rounded corner of the shaped hole on the glass plate should be larger than that of the glass. thickness.
4. When opening at an angular position of not less than 90o, the distance from the edge of the hole to the tip of the corner should be greater than 6.5 times the thickness of the glass.
5. The concave part should adopt a fillet radius not less than the thickness of the glass.

Laminated glass performance defects and treatment
2007-11-12
Reasons for the drop resistance of laminated glass
1. The bond strength between glass and film is too high, and the bond strength and impact resistance are inversely proportional to a certain range.
2. The change in film thickness, the thinner interlayer results in lower impact resistance, and whether the film is thinned or changed.
3, the thickness of the glass changes, the thicker glass has lower impact resistance.
4. There are differences in the brand and model of the film used for the interlayer, resulting in a decrease in the impact resistance of the laminated glass.
5. Changes in impact test conditions, such as test frame, temperature or procedure, inaccurate test sample size, etc.
Approach
1. The impact resistance of laminated glass is related to the bond strength of the product, so it is necessary to check the adhesion strength of the laminated glass. If the bond strength of the product is not within the specified range, determine the cause of the change in bond strength and take action. The low water permeability of the film can increase the bond strength, but the impact resistance of the laminated glass is lowere,d and the moisture content of the film is controlled within a prescribed range.
2. Measure the thickness of the laminated glass: measure the total thickness of the laminated glass, the thickness of the glass, the thickness of the film, and check whether the film is thin or not. The test piece should have the same glass and film thickness as the product produced.
3. Check the type of laminated glass, check whether the film brand and model are correct, the performance and use of different films are different, and the impact resistance is different; the different varieties of glass will also cause different impact resistance; measuring samples and glass The variety should be the same.
4. When the production and material inspections are correct, check the conditions and records of the impact specimens. For example, the temperature of the specimens will be significantly reduced at low or high temperatures. Observing the test frame, the conditions of the frame will affect the test results. Whether the edges are worn, cracke,d or wrong in size.

What are the benefits of using ultra-clear glass on the curtain wall?
2007-12-20
1. High visible light transmittance and good permeability: In addition to all the processing properties of high-quality float glass, ultra-white glass has superior optical properties and high visible light transmittance, generally greater than 91. %, the ultra-white glass plated with double silver Low-E is used on the curtain wall to increase the permeability and effectively reduce the lighting cost.
2. The ultra-white glass after tempering has a lower self-explosion rate: since the ultra-white glass raw material contains less impurities, the control of the raw material melting process is more fine, which makes the ultra-white glass have a more uniform composition than ordinary glass, thereby greatly reducing the The chance of self-explosion after tempering. It is used on the curtain wall and has a safety advantage over ordinary glass.
3. The color uniformity is better, more beautiful: because the iron content in the raw material is much lower than that of ordinary glass, the ultra-white glass absorbs less on the green band in the visible light than the ordinary glass, ensuring the consistency of the color of the glass and avoiding the cause. The aesthetics caused by the color difference of the glass curtain wall.
4. Less heat absorption: Ultra-white glass absorbs less heat than ordinary float glass, which can reduce heat loss, so it is more suitable for making double-silver Low-E insulating glass on glass curtain wall.
