The news about the shower room explosion is not uncommon. To be precise, it is not the shower room explosion, but the glass burst.
But isn’t the tempered glass used in the shower room called “safe glass”? Intersection The only disadvantage is that there is a self -explosion in terms of strength, hardness, and impact resistance.
In fact, no matter how good the shower rooms have a thousandth of self -explosion rates.
First, why did the tempered glass explode?
1. Glass itself quality defect
The glass contains impurities, such as stones and nickel sulfide crystals, which are located in the glass stress area. If the glass is heated, the volume of these debris is expanded, which is an important factor that causes burst.
2. Improper glass processing
The temperature gradient generated by the glass thickness of the glass is uneven and asymmetric in the direction of the glass thickness direction when heating or cooling, causing the tempered trend of tempered products. As the degree of tempered increases, the self -explosion rate also increases accordingly. In addition, due to improper processing, the surface of the glass causes defects such as scratches and fried mouths, which can easily cause stress concentration and cause the glass to explode.
3. Changes in the temperature difference between the external environment
Although the tempered glass can withstand the temperature difference of 300 ° C, the sudden cold and heat temperature environment makes the temperament of temperament. Especially in winter, before taking a bath, you can open the bath to warm up the shower room, and then shower to avoid most of the self -explosive situation.
So, is there a way to reduce or avoid the self -explosion of the shower and improve the safety of shower?
Second, how to reduce the possibility of the glass of the shower room?
At present, the solutions for self -explosion of shower rooms on the market are:
Select a tape glass or add a safety explosion -proof film on the tempered glass.
1. Plating glass
In the previous part, the glass of the shower room must be used for tempered glass, and the tempered glass can be further divided into ordinary tempered glass, tape glass and film tempered glass.
In terms of safety performance,
Playing glass ＞ Film tempered glass ＞ Ordinary tempered glass
The ticing glass is a PVB intermediate membrane with a PVB intermediate with a polyethylene glycol -dicythydrin as its main ingredient between two pieces of tempered glass. If the glass is broken, the fragments will also be adhered to the film, and it can still be used normally after crushing.
Pursuing 100 % safety of the shower room, directly using tape glass from the source.
2. Explosion -proof membrane
On the basis of ordinary tempered glass, add a layer of transparency and safety
Explosion -proof film,
To reduce the damage caused by the bursting of the shower room.
Paste the explosion -proof membrane like giving the shower room a steel coat “coat”. Even if the glass bursts, the glass fragments will not splash everywhere through the explosion -proof membrane, which can effectively avoid the damage caused by glass fragments to the human body. Essence
The following pictures are the burst effect of glass sticker explosion -proof membrane and unbroof explosion -proof membrane. Until the intuitive experience:
Left explosion -proof membrane: sheets are attached to the explosion -proof membrane; no explosion -proof membrane is not pasted on the right: fragments splash everywhere
The disclosure anti -explosion -proof membrane of tempered glass is the most common explosion -proof method in the industry. Compared with tape glass, it is a solution for safety and cost -effectiveness. It is generally recognized and accepted by consumers.
Below in -depth analysis of explosion -proof membranes.
Third, the shower room with explosion -proof membrane is very necessary
What is the mysteries of a thin layer of transparent explosion -proof membrane, can the glass fragments be strong?
1. Explosion -proof membrane material
Common explosion -proof membranes are usually adopted
PVC or PET
PVC is polyvinyl chloride material
, Polyvinyl chloride resin as the main raw material, add an appropriate amount of anti -aging agent, modified agent, etc., and make materials made of craftsmanship such as mixed, lax extension, vacuum suction.
PVC has the characteristics of light quality, heat insulation, insulation, moisture -proof, flame -retardant, high stretch strength, stiffness, hardness and other characteristics. It has small water absorption and has good chemical stability and electrical insulation. It is the most widely used in plastic materials. One of the decorative materials.
PET full name polyphonal acid ethyl ate
It is a kind of polymer material, which has a wide range of application. For example, the mineral water bottle that is consumed everyday is mostly PET material, which is an environmentally friendly material that can be recycled and degraded.
PET has high film, softness, opticality, weather resistance, abrasion resistance, and corrosion resistance. Good product transparency, non -toxic, anti -penetration, and light quality for processing with PET materials.
PET’s performance is relatively better than PVC materials, especially in environmental protection. As a result, PET is higher, while PVC is relatively cheap.
2. Explosion -proof membrane thickness
Generally, the thickness of the explosion -proof membrane is based on the actual thickness of the glass:
The thickness of the glass is <6mm, select 2mil (0.05mm) thickness explosion -proof membrane.
6mm ≥ glass thickness ≤10mm. It is recommended to use 4mil (0.1mm) thickness explosion -proof membrane.
The thicker glass also has an explosion -proof membrane with a corresponding thickness to meet the explosion -proof requirements. At present, the thickness of the explosion -proof membrane on the market is 12mil (0.3mm), which is suitable for bank building special protection.
3. Film method
The main ways of disclosing the explosion -proof membrane with steel glass are mainly available
Handmade film and machine film
Some brands are sent to the door of the door after installation in the shower room.
It is recommended to choose a machine film
, Precision, standard. However, due to the lack of clear inspection standards, and artificially cannot be standardized, the problem of foaming and edge of the film is inevitable.
Vacuum thermal pressure technology of machine film
Recommended that the machine film cannot be bypassed
Vacuum thermal pressure technology
Due to climatic reasons, the severe temperature difference changes thermal expansion and contraction, which is more likely to cause the shower room to burst, so there are stricter safety standards. Shower rooms that are allowed to be sold in Nordic countries will use a vacuum heat pressure technology to solidify the explosion -proof membrane and glass together, which is higher than that of ordinary explosion -proof membranes.
The domestic shower room has few brands using vacuum thermal pressure -proof membrane technology. One is that technology is difficult, and the other is that the cost is relatively high. Songlin Philton fan-shaped shower room adopts a fully automatic high-temperature vacuum film technology, which increases at least 3-4 times the strength of the explosion-proof membrane, and is more resistant to high and low temperature.
4. Single -sided stickers or double -sided stickers?
The glass glass has double -sided inner and outer sides, which causes doubts. Is the explosion -proof film affixed to a single -sided glass, the outer glass or the inner glass or double -sided glass is pasted?
Single -sided stickers, stickers on the outer glass
On the one hand, it is easy to effectively adhere to the cracking glass together; on the other hand, it is convenient for the subsequent cleaning of the glass glass.
Lotus leaf bionic Yijie technology
Some brands, such as Songlin Philton shower room, glass sticker explosion -proof membrane, inner glass and plating a layer of nano -easy cleaning coatings, so that the glass surface produces water -like hydrophobicity. Bathing water and impurities are not easy to accumulate on the glass surface, and it is easier to be easier clean.
Shower safety is the primary concern of each family. For the possibility of self -explosion in the shower room, according to the family budget, it is recommended to use the plan of tension glass or tempered glass to stick the explosion -proof membrane as much as possible.
