How to distinguish the true and also false of insulating glass?
With the development in the domestic glass processing industry along with the deepening of people's understanding of the excellent performance involving insulating glass, the application range of insulating magnifying glaas is expanding. In addition to being trusted in glass curtain wall membrane, automobile and aircraft, it's begun to enter that ordinary. The home of the people.
This is mainly for the reason that application of tempered glass online can enhance the heat insulation and sound insulation effect of doors and windows, so how the door and window products besides can shelter from wind turbine and rain, but also provide significant energy-saving effects, reducing the price tag on winter heating and summer time cooling.
The application of insulating glass is constantly expanding, and the quality requirements of insulating glass have become higher and higher. Tips on how to grasp the development opportunities with the market and provide premium and reliable insulating glass have become the research problems involving insulating glass manufacturers.
Every hollow glass is required to be heavily tested and strictly checked to create the finished product.
First introduce the different types of insulating glass and five indicators inside national standard for insulation glass:
First, the classification:
1. Slotted aluminum hollow a glass: This kind of insulation glass was introduced inside 1980s, which is relatively mature, but the processing technology is harder.
2, aluminum strip hollow glass: This kind of insulating glass started late in britain, but the manufacturing method is simple, so the application range is wide, plus the promotion is very speedy.
Two or five signs or symptoms:
1. Initial dew issue
2, sealing test
THREE, ultraviolet radiation
4, higher temperature and high humidity
5. Climate cycle test out
According to the country's testing standards, how to arrange our production in order to meet the requirements of insulation glass? Since the two different types of insulating glass have many similarities in the operation flow, they now analyze their common process movement.
1, glass cutting as well as cutting
The original glass is normally colorless float glass and also other colored glass, sunshade magnifying glaas, tempered glass, laminated glass, the thickness is usually 3-12MM, the above glass must meet the requirements of the new normal GB11614 flat glass, the actual first-class product, It can be utilized after passing the inspection.
Glass cutting can be done by hand or machine, but it must be guaranteed to meet the size and style requirements. During the operation on this process, workers should look into the surface of that glass without scratches, the internal quality is unvarying, and there should often be no obvious defects just like bubbles and slag inclusions.
2, glass cleaning and drying
Glass cleaning must be done by machine cleansing, because manual cleaning does not guarantee the grade of cleaning.
It is important to inspect the glass without having scratches before cleaning. To guarantee the adhesion of the sealant for the glass, it is best to work with deionized water. In accessory, in order to ensure the employment of water recycling, water preservation, water can be filtered to guarantee long-term use.
The cleaned glass should pass the light inspection to test the glass surface having waterless beads, water stains and other stains. If there are usually water drops, water stains as well as other stains, the machine operating speed, heating temperature, air volume and brush gap needs to be checked. Adjust until the particular effect is intact.
After washing, the glass need to be assembled into insulating glass within One hour. In addition, it is necessary to ensure that there is no abrasion and scratch between the glass and the glass. It is preferable to possess a semi-finished glass storage trolley to split up the glass sheet with the sheet.
3. Assembly of aluminum strip insulating cup
(1) Environmental requirements: The temperature needs to be between 10-30 degrees.
(2) Family member humidity requirements: The needs for relative humidity with such insulating glass are generally slightly lower, and usual conditions are sufficient.
Then again, it should be noted the fact that desiccant should be selected from qualified manufacturers to guarantee the effective use associated with desiccant.
After the desiccant will be opened, it is best to apply it within 24 hrs. Because the polysulfide rubberized has high gas permeability and poor sealing, it is critical to use a two times seal.
The butyl rubber must be used as the first close off to block the propane.
The two-component glue is used as the second close off, the main function will be the bonding effect, and the other is the gas filter effect.
Practice has proved that this life of a single-sealed insulating glass is only about 5 years, and the life of a double-sealed insulating glass can be if 20 years or possibly 40 years. Therefore, the development of double-channel sealed insulating glass is a trend of the instances.
4, glass splicing
Aluminum strip type hollow glass. After the splicing, the outer edge from the aluminum frame and the advantage of the glass must have a distance of 5-7MM. It really is used to apply the other sealant. The two-component adhesive must be evenly coated along one side to avoid air bubbles. After finish, scrape off the surface with the glass.
This completes the particular processing of aluminum strip insulating glass.
5, the keeping insulating glass
The correct keeping of the insulating glass will have an impact to the final quality of this insulating glass, whether with production or in transit as well as on site.
First of their, the design requirements on the stacking truss should take into account the characteristics of this insulating glass, and the stacking truss should have a certain inclination. Nevertheless, the bottom plane and also the side should always be maintained at 90 amounts, so that the a couple glass bottom edges from the insulating glass can be placed vertically about the stacker.
Also note that the bottom of the glass can't be stained with petrol, lime and other solvents, simply because will have different degrees of erosion on the second sealant with the insulating glass, thus affecting the sealing performance belonging to the insulating glass.
In order to enhance the effect of insulating and insulating the insulating glass, many manufacturers now inject inert gas on the hollow glass by committing to the air in the insulating glass, and such a process further improves the performance of the insulating glass.
Tips
Some of the most important methods with counterfeiting hollow glass:
ONE PARTICULAR. Replace tempered glass by using ordinary glass
2, exchange the aluminum alloy spacer with ordinary double-sided adhesive remove
3. No desiccant is included to the aluminum alloy spacer
4, only do a single seal without double seal
5, replace the bimolecular adhesive together with ordinary sealant. |
