How is laminated glass made?

Glass has been widely used in modern times and has always been a product with a large market demand. By using specific treatment methods, we can make full use of the characteristics of the glass, and can make up for its defects, no longer subject to the natural properties of the glass. For example, laminated glass can not only be insulated, but also the debris will not splash and hurt people, safe and reliable. Next, we will introduce the production method of laminated glass and float glass to help everyone understand.

First, how is laminated glass made?

        1. Cleaning: Wipe the glass with acetone and let it dry.

        2, the circumference: the PVB film strip (3-5MM width) infiltrated with the glue is embedded around the upper and lower pieces of glass to form a cavity, which is clamped with tweezers. When filling the edge, the filling port is reserved for filling glue.

        3. Glue: The degassed glue is slowly injected into the cavity through the film bag, and the gel is allowed to stand for 6-8 minutes after the end of the glue.

        4, exhaust: after standing, gently tap the glass, apply a certain pressure, try to discharge the air dissolved in the glue, gradually flatten the glass, quickly seal, clamped and fixed.

        5. Curing: After carefully checking the air bubbles, place the filled laminated glass horizontally under the sunlight (or under the violet light). (The scorpion can be removed in about 30 minutes so that there is enough light to cure it.) It can be cured.


Method for manufacturing float glass


The forming process for float glass production is done in a tin bath with protective gas (N2 and H2). The molten glass continuously flows from the kiln and floats on the surface of the relatively dense tin liquid. Under the action of gravity and surface tension, the molten glass spreads on the tin surface, flattens, and the upper and lower surfaces are flattened, hardened and cooled. After being introduced into the transition roller table. The roller of the roller table rotates, and the glass ribbon is pulled out of the tin bath into the annealing kiln, and after annealing and cutting, a float glass product is obtained.

 Compared with other forming methods, the float method has the advantages of being suitable for high-quality manufacturing of high-quality flat glass, such as no corrugated, uniform thickness, flat upper and lower surfaces, and parallel to each other; the scale of the production line is not limited by the forming method, and the energy of the unit product Low consumption; high utilization rate of finished products; easy to scientifically manage and realize full-line mechanization and automation, high labor productivity; continuous operation cycle can last for several years, which is conducive to stable production; can provide suitable conditions for online production of some new varieties, such as Electro-float reflective glass, sprayed film glass during annealing, cold-end surface treatment, etc.

For float glass, the transparency of the product is relatively good because of the uniformity of the thickness, because the tin surface treatment is relatively smooth, and under the action of surface tension, a relatively uniform surface and flatness are formed. It is better, glass with relatively strong optical properties. This float glass has particularly good decorative characteristics, and has good transparency, brightness, purity, and bright indoor light.

Do you know what is the deep processing of glass?

1. Tempered glass. It is a kind of prestressed glass which is processed by ordinary flat glass. Tempered glass has two major characteristics compared to ordinary flat glass:

(1) The strength of the former is several times that of the latter, the tensile strength is more than three times that of the latter, and the impact resistance is more than five times that of the latter.

(2) Tempered glass is not easy to be broken, even if it is broken, it will be broken in the form of particles without sharp angles, and the damage to the human body is greatly reduced.

2. Frosted glass. It is also sanded on ordinary flat glass. Generally, the thickness is more than 9 PCT, and the thickness is mostly 5 or 6 PCT.

3. Sandblasted glass. The performance is basically similar to frosted glass, and the different modified sand is sandblasted. Because the two are visually similar, many owners, even renovation professionals, confuse them.

4. Embossed glass. It is a flat glass manufactured by calendering. It is characterized by light-transparent opacity and is used in renovation areas such as restrooms.

5, wired glass. It is a kind of anti-impact flat glass made by embedding a wire or a metal mesh in a glass plate by a calendering method, and only forms a radial crack when impacted, and does not cause injury to the underarm. Therefore, it is mostly used in high-rise buildings and strong buildings.

6, insulating glass. The two glasses are kept at a certain interval by the bonding method. The air is dry in the interval, and the periphery is sealed with a sealing material. It is mainly used in the decoration project with sound insulation requirements.

7, laminated glass. Laminated glass is generally composed of an organic glue layer between two sheets of ordinary flat glass (which may also be tempered glass or other special glass) and glass. When damaged, the debris still adheres to the glue layer, avoiding the damage caused by the debris splash. Mostly used for renovation projects with safety requirements.

Maintenance and troubleshooting of glass machinery


With the rising labor costs and the relative shortage of human resources, more and more companies use automated glass machinery. The utilization rate of glass machinery is also constantly increasing. Glass machinery produced in large quantities is widely used. The movable parts of the glass machine are often the first damaged parts. It is necessary to pay attention to the maintenance of the movable parts. The movable parts (rotating or sliding) that need to be added with lubricant must be injected with the lubricant in a timely manner according to the prescribed period. Glass machinery manufacturers neglect or do not specify the movable parts of the lubricant, the company should also inject lubricants (usually lubricants), don't forget that the equipment is yours. Only the timely maintenance of the glass machine can reduce the premature damage of the glass machine. Each time the glass machine is started up, the glass machine should be inspected and its working condition recorded. The operator must transfer the record of the mechanical operation status of the glass machine during the shift. The glass machinery should be carefully observed during the start-up and production operation. It is found that the equipment has abnormal sound or abnormal vibration, stop when it is vibrating as soon as possible, check the fault point, and replace the problem parts in time to avoid causing the fault to expand and cause serious personal injury. Or glass mechanical parts are badly damaged. Replace worn parts that are not completely damaged in time to avoid damage to the valuable fittings used with them. In particular, it is necessary to pay attention to the dust collection and cleaning treatment of the glass mechanical equipment such as the LOW-E glass film removing machine and the glass edger to prevent the dust from entering the movable part and causing mechanical damage to the glass. The leakage protector should be periodically reset to prevent the leakage protector from failing. Glass machinery must be reliably grounded to prevent people from getting an electric shock.

First, the lubrication of the washing machine

In order to prevent gear necrosis caused by excessive wear of the wear machine, the washing machine must be properly lubricated. The glass coating process requires a very high degree of cleanliness of the glass. A small amount of lubricating oil is not allowed to enter the cleaning area, so greases with good mechanical stability and adhesion should be selected. Focus on lubrication of the drive chain, helical gears and drive shafts.

1 Use a plastic sheet to isolate the parts to be lubricated from the cleaning area to avoid grease contamination.

2 Lubricate the joint surface of the chain, the gear, the drive shaft chain roller and the chain plate.

3 pairs of drive chain and roller, so that it is evenly lubricated.

4 Wipe off excess grease with a clean cotton cloth.

Second, the transfer roller calibration

The washing machine adopts the method of pinching glass, the lower roller table is fixed, and the height of the upper roller table can be adjusted to ensure uniformity of the force of the glass and smooth transmission. The lower roller table is driven by the drive shaft and gear system and requires periodic inspection of the bearings and horizontal and vertical levels. The upper roller table is fixed by two water-lubricated plastic bearings at both ends and is free to rotate. Since the plastic bearing is easy to wear and increase the gap after using for a period of time, the two ends of the upper roller are unbalanced, so that the original glass sheet is easily deflected in the washing machine. For the upper roller table, we add a fixed end block clamp and periodically measure the height change, corresponding to the calibration or replacement of the bearing to adjust the pressure of the roller.

Third, the adjustment of the brush height

The inlet cleaning machine mainly cleans the surface of the original glass through a total of 132 disc brushes in three rows, and adds a liquid polishing agent to ensure effective grinding of the glass surface and remove stubborn stains. In order for the disc brush to form an effective roll on the glass surface, the height of the disc tip is generally set to 1.5 mm below the surface of the glass sheet. As the bristles of the disc wear, it is necessary to periodically lower the height of the disc to ensure the quality of the cleaning.

Fourth, the cleaning of the water tank and the water tray

The inlet cleaning machine adopts the method of gradually cleaning and recycling the three-stage water quality. Five water tanks and corresponding water receiving trays are respectively arranged in the lower part of the conveying platform for storing the washing water. Since the water itself is contaminated while cleaning the glass, some polishing agents and the like are gradually deposited in the water storage tank, and it is necessary to periodically perform flushing and cleaning to ensure the water quality is clean.

5. Smoothness of polishing agent and water spray pipe

The inlet cleaner uses an aqueous solution of aluminum or lanthanum oxide as a polishing agent and is added to the brushing process of the disk brush through a water spray pipe between the upper roller tables. Since the solid aqueous solution polishing agent is used, when the concentration is too large, the nozzle is easily clogged. When the polishing agent nozzle is blocked during use, the concentration of the polishing agent after dilution should be adjusted in time. To clean the polish and spray pipe, follow the steps below.

1 Remove the cleaning machine stop plate, raise the upper roller table of the washing machine, and turn off the power supply and water supply valve.

2 Loosen the fixing bolts at both ends of the nozzle and remove the nozzle.

3 Use a high-pressure water gun to drive pure water from the inlet of the nozzle into the nozzle to form water pressure, observe the water discharge of each nozzle, and use a paper clip to clear.

4 Clean the nozzle, install it back to the original position, tighten the bolts, and keep the nozzle direction unchanged until it is removed.

6. Cleaning and adjustment of the air knife drying area

The last tank of the washing machine is filled with high-purity water heated (temperature is about 45 °C), so the water stain attached to the surface of the original glass sheet can be blown away and evaporated under the high-strength wind of the air knife after entering the drying zone. . The angle between the air knife edge and the original glass plane is at an acute angle. Each time the air knife is removed or its position is changed, the angle should be measured and kept unchanged.

1 Clean the glass debris, labels, paper jams, etc. in the drying area, and wipe the air knife, roller table and other parts with a clean cotton cloth to ensure clean.

2 Remove the primary filter plate and the secondary filter bag for the fan, and use the compressed air to blow out the dust inside, and check for damage or blockage, and replace it regularly.

3 Use the saw blade to plunge into the air knife edge and check if there are any impurities such as filter bag fibers blocking the knife edge.

Through these years of production practice, Goode realized that as long as the maintenance and maintenance of the inlet cleaning machine is carried out in strict accordance with the above procedures, the cleaning effect of the original glass film can be ensured to a large extent under the normal process conditions. Ensure the quality of coated glass products is stable.

Maintenance of glass machinery is one of the main responsibilities of the operator to maintain the normal state of the equipment and to carry out the daily work required to extend the service life. The maintenance of glass machinery equipment is completed, which can reduce downtime and maintenance costs, reduce product cost, ensure product quality, and improve production efficiency. Generally, the maintenance work of glass machinery equipment is divided into two types: daily maintenance and regular maintenance.

The daily maintenance of glass machinery equipment includes two types of maintenance and weekend maintenance, which is carried out by the operator. Each class of maintenance requires that the operation staff must do the work in each shift: check all parts of the equipment before the shift, and lubricate according to the regulations; the specified inspection items should be recorded on the inspection card after inspection, and then confirmed. use equipment.

In the operation of glass machinery equipment, the equipment should be used in strict accordance with the maintenance operation rules. Pay attention to the operation of the equipment and observe the abnormality. It should be handled in time. The fault that the operator cannot eliminate should be notified to the maintenance worker for repair and repair, and the maintenance worker should be on the "fault repair order". Make a maintenance record. Before going to work, use 15 minutes or so to carefully clean and wipe the equipment, and record the condition of the equipment on the handover book to handle the handover procedure.

Weekend maintenance is mainly for the operators to thoroughly clean, wipe and oil the equipment for 1~2h every weekend and holidays, and check and evaluate according to the "four requirements" of equipment maintenance.

In addition, the regular maintenance of the glass machinery and equipment is carried out by the operator under the guidance of the maintenance workers. The glass machinery equipment produced by the two shifts is maintained for about 3 months, and the dry grinding and dusting equipment is maintained once a month. The working time is calculated according to the complexity factor of the equipment, which is 0.3~0.5h per unit, depending on the structure of the equipment. Maintenance and requirements for precision, heavy-duty, and rare equipment are specified separately.
