Fire resistant glass can be divided into:

　　1.Composite fireproof glass(expressed in FFB)

　　2.Single piece fireproof glass(represented by DFB)

　　Fire resistant glass can be divided into:

　　1.Heat insulating fireproof glass(Class A)

　　2.Non insulated fireproof glass(Class C)

　　Fire resistant glass can be divided into five grades according to fire resistance limit:

　　0.50h,1.00h,1.50h,2.00h,3.00h

　　Explanation of relevant issues:

　　1.What is class a fireproof glass?

　　Fire proof glass meeting the requirements of fire resistance integrity and fire resistance and heat insulation at the same time.It includes composite fire-proof glass and pouring fire-proof glass.This kind of glass has the properties of light transmission,fire prevention(smoke,fire and heat radiation),sound insulation and impact resistance.It is suitable for building decorative steel and wood fire doors,windows,upper lighting,partition walls,daylighting roofs,smoke retaining vertical walls,perspective floors and other building components that need to be both transparent and fireproof.

　　2.What is class C fireproof glass?

　　Single piece fire-resistant glass that only meets the fire integrity requirements.This kind of glass has the characteristics of light transmission,fire prevention,smoke separation and high strength.It is applicable to fireproof glass partition walls,fireproof windows,outdoor curtain walls,etc.without heat insulation requirements.

　　3.Why is there no class B fireproof glass?

　　In the 2009 edition of safety glass for building-Part 1:fire resistant glass(gb15763.1-2009),class B fire resistant glass is cancelled and only class A and class C fire resistant glass are retained

　　4.What is hollow fireproof glass?

　　It is a high-efficiency sound insulation glass made of two(or three)pieces of fire-proof glass,using high-strength and high air tightness composite adhesive to bond the glass with the aluminum alloy frame containing desiccant.It has good heat insulation,sound insulation and weather resistance,will not produce bubble free color change,good permeability,beautiful and applicable,and can reduce the dead weight of the building.

　　5.What is laminated glass?

　　Laminated glass laminated glass is also called laminated glass.It is made of two or more pieces of float glass sandwiched with a strong and tough PVB(ethylene polymer butyrate)adhesive film,pressed by a hot press and discharged as much air as possible,and then put into a high-pressure steam kettle to dissolve a small amount of residual air into the adhesive film under high temperature and high pressure.Compared with other glasses,it has the properties of shock resistance,anti-theft,bullet proof and explosion-proof.

　　6.What is special fireproof glass?

　　The fire-proof glass of glass substrate with special components mainly includes borosilicate glass,aluminosilicate glass-ceramic glass.The softening point of the glass is higher than 900℃,the coefficient of thermal expansion is low,and generally it will not crack or deform due to high temperature under strong flame;High mechanical strength,good bending resistance,compression resistance and stability.It is difficult for people to accept the high production cost and high market price.

　　7.What is high strength single piece cesium potassium fireproof glass(chemical fireproof glass)

　　It is a new type of functional building material with good light transmission performance and fire retardant performance.At ordinary times,it is as transparent as ordinary glass.After a few minutes in case of fire,the chemical toughening layer can prevent the spread of flame and heat transfer,and put the fire in a small area near the ignition point,playing a fire protection role.It still has good fire resistance at high temperature above 1200℃.This transparent fireproof safety glass can be used as an ideal fireproof material for fire doors,fire windows and fire partitions of***hotels,cinemas,exhibition halls,airports,gymnasiums,hospitals,libraries,commercial buildings and other public buildings,as well as other civil and public buildings without fire zoning requirements.

　　8.What is wired fireproof glass?

　　The composite glass body is made by adding metal wires and nets into the interlayer of organic film or inorganic adhesive between two layers of glass.

　　It has all the properties of fire-proof glass,and has good fire resistance and integrity.If the fire resistance time of fire-proof glass is exceeded,the glass will break,but its own metal wire or net makes the glass stick into a whole,which will not collapse and puncture,and will not fall and hurt people.It can prevent air flow to a certain extent,and has a good blocking effect on the spread of fire.Wires or nets in the glass prevent fragments from flying away.Even when the glass is broken by high-intensity earthquake,storm,impact,etc.,it is difficult for the fragments to fly away.Therefore,compared with ordinary glass,the glass fragments will not splash and hurt people,and the safety is higher and better.Even when the glass is broken,there is still a metal wire net connecting the glass together,so it is impossible for thieves to break in and steal easily.This anti stealing function of fire-proof wired glass is welcomed by people.The defect is poor light transmittance.

　　9.What is the pouring type fireproof glass?

　　It is made of two layers of glass(three layers of glass can also be used for special needs)and sealed with special flame-retardant adhesive strips.The fire-proof glue poured in the middle,after curing,is in the form of transparent gel and bonded with the glass.In case of high temperature,the transparent gel like fireproof adhesive layer in the middle of the glass will harden rapidly to form an opaque fireproof insulation board.It can not only prevent the flame from spreading,but also prevent the high temperature from conducting to the back fire surface.It is applicable to fireproof doors and windows,building patios,atriums,shared spaces,and partition walls of computer rooms.

　　10.What is thin coated fireproof glass?

　　It is made by spraying fireproof transparent liquid on the surface of single-layer or multi-layer flat glass substrate,drying and curing.When the thin coated fireproof glass encounters fire,the fireproof protective layer will be heated and expanded to form a fireproof protective layer to protect the base plate glass and prevent the spread of fire.
