How to prevent glass mildew?

Glass mildew is a big problem for glass industry, with high temperature and humidity characteristics of the weather in summer and winter, the glass mildew run into the peak. So how to prevent glass mildew become the primary task of many glass companies.

On one hand, the glass mildew related to the glass surface characteristics, but also related to float glass packaging measures taken before the anti-mildew packaging sealing degree, storage and transportation conditions. When the float glass molding, annealing, are generally taken online packaging, the temperature of the glass is about 50 ~ 100 ℃. Packed glass must be inventory, transport to the user after long time shipping. If it is high temperature, high humidity season, improper storage, the glass may appear mildew. 
Packaging can be made in hot station or in cold station with paper or anti-mildew powder.

1.Better be stored in well ventilated warehouse;
2.do not put the glass box directly on the wet ground of warehouse;
3.Do not store the glass outdoors and in direct sunlight. 
Anti-mildew for glass measures:
It is best to use professional anti-mildew powder, we use best anti-mildew products in our glass and do prevention, mold preparation in advance to make sure that our float glass will keep in good condition when arrives customers' warehouse.

What matters need attention in Glass Blasting Processing?

Sandblasting is one process to produce frosted glass, but there are many problems need attention during blasting progress.
What is sandblasting?
Sandblasting is the use of compressed air as the driving force to form a high-speed jet beam will be sprayed high-speed jet to the surface of the glass to be processed. Blasting the surface of the glass surface or shape changes, due to abrasive impact on the glass surface and cutting effect, so that the surface of the glass to obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the glass surface is improved, thus improving the fatigue resistance of the glass, Increasing the adhesion between it and the coating to extend the durability of the coating, but also conducive to leveling and decoration paint.

So the use of sandblasting machine is that we often use, a lot of attention need to pay attention in use, so as to ensure the use of the results. There is also a safety issue with the sandblast itself and its usage.
1, before work must wear protective equipment, not allowed to work naked arm. There shall be no less than two persons at work.
2, the gas tank, pressure gauges, safety valve to be regularly verified. The tank is drained twice a week and the filter in the sand tank is inspected once a month.
3, check the ventilation pipe and sandblasting door is sealed. Five minutes before work, ventilation and dust removal equipment shall be activated. When the ventilation and dust removal equipment fails, the work of the blasting machine shall be prohibited.
4, compressed air valve to open slowly, air pressure is not allowed to exceed 0.8MPa.
5, sand blasting size should be adapted to the requirements of the work, generally applicable between 10 to 20, sand should be kept dry.

6, blasting machine work, prohibit unrelated personnel close. Cleaning and adjustment of operating parts, should be shut down.
7, not allowed to blow the body with compressed air dust or joke.
8, after the work, ventilation and dust removal equipment should continue to run for five minutes and then closed to discharge indoor dust to keep the venue clean.
9, the occurrence of personal and equipment accidents should be kept on-site and report the relevant departments.

What's the effect of inert gas for the energy-saving function of insulated glass?

The inert gas in insulated glass compared to air, the density, thermal conductivity is small, it can slow down the middle layer of thermal convection, reducing the thermal conductivity of gas, thereby reducing the heat transfer coefficient of insulating glass, help to improve the insulating glass of the insulation performance and energy saving effect. 
Argon is the most commonly used inert gas for filling the spacer layer of insulating glass, which is relatively easy to be extracted and the price is lower. 
Hollow glass filled with inert gas 

Hollow glass is filled with inert gas filling, can increase the glass thermal insulation function, which has energy-saving advantages are compared to the hollow glass that with not the inert gas filled glass, to achieve the following effect: 
Winter heat can be retained indoors 
The heat is blocked outdoors in the summer 
Energy-saving insulation 
After filled with gas, can reduce the pressure difference between inside and outside, to maintain balance of pressure, reducing the pressure caused by the glass burst. Filled with argon, can effectively improve the insulating glass K value and can achieve following results: 
Thereby reducing the condensation of the glass inside the room 
Improve the comfort level 
After filled with gas hollow glass is less prone to condensation and frost 
Observation the outside world clearly 

As argon gas as inert gas has its own characteristics can slow down the hollow glass thermal convection, but also can greatly improve the effect of noise reduction, so better insulation insulating glass with argon gas. 
Improve the sound insulation effect 
Because filled gas is a dry inert gas, the air inside the hollow glass cavity can be replaced by air, so the environment inside the cavity is kept dry and the service life of the molecular sieve in the aluminum interval frame can be prolonged. 
Standard for inert glass filled with inert Gas 
There is not specified for inert gas filled with hollow glass, but in general, not less than 90%.

How to make glass more heat saving in winter?

1, prefer a flat window 
Glass flat windows(windows that can be opened 90 degrees) will be much better than the glass sliding window. Glass flat window is generally sealed with plastic strips,glass sliding windows sealed with a top. When close the glass flat window, the isolation of dust and rain will be stronger than the glass sliding window. The glass flat window generally use two-point lock or lock to lock close while the glass sliding window is a hook lock or a lock, so the air tightness of the glass flat window is also much stronger.

2, bay window / floor windows less than 30% of the wall 

Glass bay window and glass floor to ceiling windows, because it is more and more beautiful design, the large number of residential use this kind of glass window. But these two glass windows are often not conducive to indoor insulation, especially in the northwest glass window is more suitable for the use of this window. Even if used, the area should not exceed 30% of a wall.

3, residential window ratio 1 / 7-1 / 10 
In home decoration, the window area should not be opened too large, the larger the window area, resulting in the greater room heat loss, reasonable residential window ratio (window area and the room floor area ratio) should be 1: 7 to 1: 10.
Sun Global Glass produce various glass for window glass, such as reflective glass, tinted glass, tempered glass, insulated glass etc, with good price and best quality.

How to identify tempered glass and ordinary glass?

Glass is an essential part of the doors and windows, the early construction of glass doors and windows are single-layer flat glass. With the development, the toughened glass, insulating glass, laminated glass, bullet-proof glass are a new choice. Today, most of the doors and windows use tempered glass. 
1, look at the glass logo 
Look at the corners of the glass of 3C logo, painting 3c mark (the kind of no scraping) are basically tempered glass. Toughened glass processing is to cut ordinary float glass into the required size, and then edging, cleaning, printing paint with the China national mandatory certification ccc mark(CE mark in European market), into the steel furnace. After firing the finished glass can not be cut or in any processing. The ink after the high temperature through the general situation is not scraping. (If your home on the 3C logo can be wiped off the hand, it can be concluded that the basic is a fake toughened glass) 

2, to see whether or not with slight deformation 
From the side of the glass to see whether there is a slight deformation, because the glass through the high temperature firing, there will be a slight deformation of the phenomenon, which can only be seen from the side of the glass, the front is generally difficult to see. 
3, see the glass fragments 
Ordinary glass broken into large sheet, sharp, easy to hurt. Toughened glass is broken into granular, the corner is very blunt, not easy to hurt human beings. 

Characteristics of Tempered glass 
1, with high impact strength, 5 times higher than ordinary glass; bending strength, 5 times higher than ordinary flat glass; thermal stability, can withstand temperature changes of 200 ℃; smooth, transparent, non-cutting and so on. In case of super impact damage, the debris was scattered small granular, no sharp edges and corners, it is also known as safety glass. 
2, Glass will be a slight thickness thinning after tempered. 
Thinning of the reason is because the glass in the hot melt softening, after strong winds to make it fast cooling, so that the crystal internal crystal gap becomes smaller, the pressure becomes larger, so the glass after tempered to be thinner than before. Under normal circumstances 4-6MM glass after thinning 0.2-0.8MM thinner, 8-19MM within 0.9-1.8MM thinner.

Which kind glass will use to seal the balcony?

Seal balcony can proof dust, rain, sand, to keep the balcony clean, so there are many families like balcony design, but what kind of glass can use to seal balcony? Which kind of glass will be better? 
First, the ordinary glass 
Ordinary glass is the most common glass on the market, the glass price is lower and the thermal stability is relatively poor, impact resistance is not enough, if subjected to external forces is easy to broken. Not only that, the transparency will reduce in the wet condition. so not recommend this kind of glass as a good choice. 
Second, the laminated glass 
laminated glass is composed of two or more pieces of glass, and multi-layer glass sandwiched between one or more layers of organic polymer interlayer, after a special high-temperature preload Vacuum and high temperature and high pressure process, making the glass and interlayer permanently bonded as a whole. 
After such treatment, even if the glass fragmentation, debris will be stuck on the film, the broken glass surface remains clean and smooth. This design effectively prevent the debris and piercing through the occurrence of falling events, to ensure personal safety. 

Third, the insulating glass 
Hollow glass is two or three pieces of glass in the middle of the hollow glass surrounded by the use of high-strength and high-air-tight composite adhesive seal. This design of a hollow layer between the glass block heat and noise transmission, can achieve the effect of noise insulation. This glass is also known as double glazing. For the sound insulation, this kind of glass is a good choice. 

Fourth, tempered glass 
Tempered glass is ordinary glass after high temperature processing cooling is made, fifth the hardness of ordinary glass, so the tempered glass is also known as safety glass. First, because the glass after the break to become granular and will not hurt human beings. Tempered glass can be processed into single-layer glass, insulating glass, laminated glass, strength, impact resistance, excellent thermal insulation performance, is a better choice for balcony. 

What’s the best choice for tempered glass used as show door glass?

On the home bathroom facilities, increasingly high demand for the shower room space is small, convenient and clean, fashion. But the different qualities of show door glass exist on the market, shower door self-explosion accidents occur sometimes. Some basic knowledge need to know before to build your shower door room. 

Why tempered glass self explode? 
professionals says, part of the reason for the occurrence of Toughened glass self-explosion, except the degree of tempering, the existence of improper use, improper installation, the temperature difference is too huge, and external shocks may also lead to tempered glass explosion. 
The tempered glass more thicker, the glass more safe? 
The tempered glass after the burst will become into granular, the risk of harm to human body compared to ordinary glass is much lower. The thickness of the toughened glass in 4mm, 5mm, 6mm, 8mm, the toughened glass quality is much better. More than 10mm thick and the quality is difficult to meet the full requirements of tempered glass. Some factories like to mislead consumers, the thicker the glass more secure. But the truth is not like that. As long as the toughened glass can withstand the human body bath, sauna temperature, the proposed 8mm tempered glass quality is much better for shower door with longer service life. 

The pattern of the glass look better, the better quality? 
There are a lot of glass shower room glass patterns are not in tempered glass quality, engraved pattern of glass pressure bearing capacity is very small, and even has not been pasted explosion-proof film, if use in improper circumstances easy to broken. Therefore, the more clear the better for tempered glass used as shower screen. Sun Global Glass bathroom shower door glass adhere to the design of good permeability of the explosion-proof tempered glass. 
Safety toughened glass - low self explosion possibility 
Toughened glass belongs to safety glass and is a kind of prestressed glass. To enhance the strength of glass, chemical or physical method is usually used to form compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first canceled, so the bearing capacity is enhanced. Glass self-wind pressure, cold and heat, impact and so on. Toughened glass after the burst into a granular, and the low rate of self-explosion.Sun Global Glass produce tempered safety glass under ISO9001 standard and our tempered glass have passed BS 6206 UK safety glass standard, EN 12150 CE European safety glass standard, Chinese Safety Glass Compulsory Certification (CCC).

What’s the advantages of LOW E glass?

The Low-E glass has very good characteristics and make Low-E glass obtain an increasingly wide range of applications in the developed countries, do you know the good features of Low e glass? 

Excellent thermal performance 
The heat loss of exterior door and window glass is the main part of the building energy consumption, accounting for more than 50% of building energy consumption. The research data show that the glass surface heat transfer to radiation-based, accounting for 58%, which means to change the performance of the glass to reduce the loss of heat, the most effective way is to suppress the radiation on its inner surface. The emissivity of ordinary float glass is as high as 0.84, and when it is coated with a silver-based low emissivity film, its emissivity can be reduced to below 0.15. Therefore, the use of Low-E glass building windows and doors, can greatly reduce the radiation by the indoor heat transfer to the outside, to achieve the desired energy saving effect.

Good optical properties 
Low-E glass transmittance is 0% -95% range theoretically (6mm clear float glass is difficult to achieve) and the visible light transmittance represents the indoor lighting. Outdoor reflectivity is about 10% -30%, and outdoor reflectivity is visible light reflectivity, representing the intensity of light or dazzling degree, so far, China Construction department requires the curtain wall of the visible light reflectivity can not more than 30%.

Low e glass does not use separately in modern building, it normally process into low e insulated glass to use as glass facade, glass curtain wall, glass window and glass door. The common composition is 5mm+5mm or 6mm+6mm Low e insulated glass with 9A/12A air or argon gas spacers, if you have more interest in low e glass or low e insulated glass, please do not hesitate to contact me, my email address is szsgg02@szsgg.com. 

What’s the requirement for glass to use on curtain wall?

Glass curtain wall should be safety glass, mainly tempered safety glass, laminated safety glass, insulated safety glass, fire-resistant glass, solar control coated glass and low-E coated glass and so on. Specific selection requirements are as follows: 
1. Curtain wall glass should use safety glass, the thickness of the single glass panel should not be less than 6mm safety glass, full glass curtain wall thickness should not be less than 12mm safety glass.
2. When the glass curtain wall with heat-reflective coating of glass, coated reflective glass or on-line thermal spray coated glass. Reflection coated glass for the appearance of the float glass quality and technical indicators should be consistent with current national standard "float glass" (GB11614) in the superior product or first class regulations. 

3. The insulated glass for the curtain wall shall be double-sealed. The insulated glass of the frame wall shall be made of poly sulfide sealant and butyl sealant and the insulated glass of semi-hidden frame curtain wall shall be made of silicone structural sealant and butyl sealant. The coating layer shall be in the second or the third layer of hollow glass.
4. Curtain wall of laminated glass should be used polyvinyl butyral (PVB) film dry synthesis of laminated glass. In Point-supported laminated glass curtain wall, the laminated film (PVB) thickness can not less than 0.76mm.
5. Tempered glass should be consistent with GB9963 "tempered glass" of the regulations.
6. All curtain wall glass shall be edge grinded or polished.
What’s the requirement for glass to use on curtain wall?

What’s the difference between insulated glass and laminated glass?

Insulated glass is composed of two or more pieces of flat or curved glass, separated by aluminum spacer and sealed with a sealant. As the hollow glass is formed by the dry gas space between glass and the edge of the insulated glass is sealed with a sealant, the hollow glass cavity filled with dry air or inert gas, the part of the gas is long-term sealed in the cavity, not with the outside air convection, therefore, Insulated glass on both sides of the heat will not reduce because of the gas between the glass convection and will not take away heat. On the other hand, the air is a poor conductor of heat, and the two layers of glass separated by a sealing gas are less heat-transferable to each other, thereby providing good heat insulation. In addition, in the insulating glass on both sides of a large temperature difference, because a piece of glass only feel the temperature, the two glass surface will not have a large temperature difference. Therefore, when the temperature difference between the inside and the outside of the hollow glass is not particularly large (≥100℃), frost and condensation do not occur. In addition, it should be noted that the hollow glass is not a vacuum glass, hollow glass cavity gas pressure basically consistent with the outside world, or very likely to cause glass broken. 

The biggest difference is that the laminated glass is not sealed, which will sandwich the air has a certain humidity, and with the outside world (indoor, outdoor) air convection. Indoor and outdoor air and glass inter-layer in the air convection will cause condensation frost, not only affects the line of sight and lighting, when the temperature rises, the glass surface of the frost into the water when the water in the lower part of the laminated glass. Second, suspended particles in the air, dust in the sandwich inside and outside the convection inevitably be brought into the sandwich adhesion in the glass surface, the passage of time will stain the glass sandwich inside, and difficult to clean.
