First, the purchase of tempered glass guide
The following are the same as the "
Tempered glass is a deep-processed glass product that is made by cutting, grinding, washing, drying, and then heating it to near glass softening temperatures as required by the product.
The following are the same as the "
Construction of glass is China's national certification and accreditation supervision and management committee compulsory certification of one of the safety glass products. Consumers in the purchase of building with tempered glass, should note the following:
The following are the same as the "
Look at the quality of inspection
The following are the same as the "
View the quality of the product. Tempered glass should not have cracks, missing angle; burst edge and scratches should not exceed GB15763.2-2005 standard requirements. At the same time, the production of tempered glass used in the original glass, the quality should meet the requirements of the corresponding product standards, glass from the original defects caused by the appearance of tempered glass quality defects should meet the requirements of the corresponding product standards.
The following are the same as the "
Also, check the flatness of the flattened glass. For flat tempered glass products, GB15763.2-2005 standard arc bending should not exceed 0.3%, waveform curvature should not exceed 0.2%.
The following are the same as the "
See signs check the certificate
The following are the same as the "
Since 2003, since the implementation of safety glass products certification, the majority of the construction of the country's glass manufacturers have passed the product certification, enterprises must be in the sale of the product on the body screen printing or paste the 3C logo, or in its minimum packaging and accompanying documents (Such as certificate of competency) in the plus 3C logo. When purchasing products, please check whether there is a 3C logo, and according to the enterprise information, factory number or product certification, etc. through the network to see the product manufacturers have passed the mandatory product certification (with 3C certificate and valid), product model Whether the certification status of the certificate is valid if the enterprise has passed the scope of compulsory certification.
The following are the same as the "
Check the product inspection report
The following are the same as the "
Construction of glass as the impact of personal and property safety products, has been listed as the focus of government supervision and inspection, regular manufacturers by the cycle to accept the supervision department inspection. Therefore, the production enterprises should be able to provide a quality inspection departments issued by the inspection report, otherwise, the quality of the product quality is lack of basis.
Second, the maintenance and maintenance of tempered glass skills
The following are the same as the "
1, pay attention to protect the corners of tempered glass
The following are the same as the "
If the corners of the tempered glass are damaged, the risk of glass blew is multiplied. Because the stress point of the tempered glass is all concentrated in the corners, the protection of the corners is particularly important, and it must be used with caution when the corroded glass can not be processed.
The following are the same as the "
2, to avoid the tempered glass for a long time in the pressure state
The following are the same as the "
For the indoor beauty, many families will choose to use tempered glass as a desktop table, coffee table, the general tempered glass to withstand pressure between 70mpa to 100mpa, the pressure by the glass force area is the maximum pressure it can bear. Converted to the quality of the goods = (pressure * area) / 10, if not necessary, do not re-tempered glass desktop long-term placement of heavy objects, to avoid the pressure to reach the critical point leading to tuffed glass broken.
The following are the same as the "
3, to avoid hot and cold uneven
The following are the same as the "
If in extreme cases, at the two ends of a glass were applied to the high temperature and low temperature, then 90% of the glass will blew, for example, lit incandescent pouring cold water, incandescent glass will burst. Although for the tempered glass, this situation will happen very small, but not afraid of ten thousand afraid of.
The following are the same as the "
4, away from acid and alkali substances
The following are the same as the "
To avoid the tempered glass exposure to sodium hydroxide (NaOH aerosol) and other alkaline substances and hydrofluoric acid (HF), the glass is essentially silica (SiO2), the above substances will be a chemical reaction.
The following are the same as the "
5, prohibit the use of sharp, hard objects hit the glass corner
The following are the same as the "
As the stress point of the tempered glass concentrated in the corners, the corner once broken, the tempered glass will increase the probability of rupture, so for the sake of home safety, do not use sharp, hard objects to hit the tempered glass corner.
The following are the same as the "
Third, the cleaning of the glass
The following are the same as the "
1, daily use of wet towels, newspapers
The following are the same as the "
In daily cleaning, wipe with a wet towel or newspaper, wet towel can erase most of the stains, the newspaper can erase the glass surface of the water mark. Stubborn stains can be towel dipped in beer or warm vinegar wipe, you can also glass cleaning agent, avoid the use of strong acid and alkali solution clean. Winter glass surface prone to frost, can be dipped in salt water or white wine to wipe, the effect is very good.
The following are the same as the "
2, plastic wrap to re-birth to the glass
The following are the same as the "
The oil-stained glass is very laborious and requires only a plastic wrap and a wet cloth to keep the glass fresh. In the glass filled with cleaning agent, paste a plastic wrap, so that the solidification of the oil softening, after ten minutes, tear off the plastic wrap, and then wipe the wet cloth to wipe all the oil, leaving no trace, smooth as new The
The following are the same as the "
If there is oil on the glass, can be wiped with rubber soaked in water, and then wipe with a damp cloth can completely remove the traces of oily pen; if it is paint, cotton can be dipped in vinegar scrub; clean cloth with dipped in alcohol wipe the glass, crystal.
