Glass is an item that we often touch and use in our daily lives. From daily necessities such as glasses to architectural decoration materials such as glass curtain walls, glass has made a great contribution to the development of world civilization. For example, the tempered glass that we often hear about is often used in the manufacture of various safety protection products with outstanding performance.
Tempered glass
Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the resistance of the glass itself. Wind pressure, weather resistance, impact resistance, etc.
Hollow glass
Insulating glass was invented by the Americans in 1865. It is to seal two or more glass edges together, form a static dry gas between the glass, and have a certain vacuum performance, using high-strength, high-airtight composite adhesive Adhesive, which bonds the glass sheet to the aluminum alloy frame containing the desiccant. Most of them are produced and formed by large factories. There will be no stains in the middle, no water, no condensation, and good heat insulation, sound insulation and heat preservation performance. .
(1) The effect of heat insulation, sound insulation and anti-condensation is much better than that of monolithic glass, which can reduce the noise by 27-40 decibels;
(2) The wind pressure resistance of insulating glass is 15 times that of single glass;
(3) Many people choose such glass windows when sealing the balcony;
(4) Insulating glass is afraid of moisture, and the sealing material will age and leak after the sun and rain, and then the middle of the hollow glass will fog and mold, which will affect the appearance.
Laminated glass
Laminated glass, also known as laminated glass, is a strong PVB (ethylene polymer butyrate) film sandwiched between two or several pieces of float glass, which is pressed by a hot press to exhaust the air as much as possible, and then put it in The high temperature and high pressure is used in the high-pressure steam kettle to dissolve the remaining small amount of air into the film. Compared with other glass, it has the performance of shockproof, anti-theft, bulletproof and explosion-proof. After the laminated glass is broken, it is stuck together due to the glue, and it is rarely scattered.
The strength of ordinary laminated glass is not high, and it is basically the same as a single piece of ordinary glass. Laminated glass synthesized with tempered glass has strength and safety performance. It is often used for indoor partitions, fences, stage floors, and large-area curtain walls. In addition, laminated glass is also afraid of exposure. The transparency of PVB in laminated glass will decrease after exposure to sunlight, and it is easy to bubble in the middle due to poor processing.
The difference between insulating glass and laminated glass Laminated glass has excellent shock resistance and explosion-proof performance, while insulating glass has better thermal insulation. Laminated glass and insulating glass have the effect of sound insulation and heat insulation to a certain extent, but there are different differences between the two in terms of sound insulation. Laminated glass has good seismic performance, so when the wind is strong, the possibility of noise caused by self-vibration is small, especially for medium and low frequencies; hollow glass is prone to resonance, but when it comes to isolating external noise, hollow glass is slightly better Advantage.
The direct manifestation of the two types of glass is the use of the sun room. Generally, the roof of the sun room is made of laminated double-layer tempered glass, and the facade glass of the sun room is made of insulating glass, because if it encounters falling objects from high altitude, the safety of laminated glass is relatively high, and it is not easy to be completely broken. The use of insulating glass for the facade glass can better achieve heat insulation and keep the sun room warm in winter and cool in summer. Nowadays, with the upgrading of technology and materials, insulating glass has new requirements. In particular, the adhesive, which plays a crucial role in sealing, directly affects the airtightness of the entire insulating glass. In order for the new insulating glass to achieve: high permeability, high vacuum, high weather resistance, high temperature resistance, heat insulation and sound insulation, many manufacturers have begun to use D235 low-melting glass powder developed by the Anmi Micronano team as a low-temperature adhesive.
