Basicintroduction

Safetyglassreferstotemperedglass,laminatedglassandotherglassproductsmadeoftemperedglassorlaminatedglassthatmeetthecurrentnationalstandards,suchassafetyinsulatingglassWait.Accordingtodifferentneeds,safetyglasscanbemadeofordinaryglass,temperedglass,heat-reinforcedglass,orhollowglass.Safetyglasshasgoodsafety,impactresistanceandpenetrationresistance,andhasthefunctionsofanti-theft,explosion-proofandanti-impact.

Locationofuse

Safetyglassisusuallyusedinsomeimportantfacilities,suchasbankgates,valuablesdisplaycabinets,doorsandwindowsofprisonsandcorrectionalcenters.Thesepartsmaybecontinuouslyattackedbybanditswithvariousweapons.Thehigh-strengthsafetyglasscanresistpenetrationwithinaperiodoftime,gainingenoughtimeforotherdevicestoreact.Someofthemostfamousculturalrelicsintheworld,suchasthe"MonaLisa"andthe"DeclarationofIndependence"areprotectedwithsafetyglass.

BulletproofglassismadebybondingmultiplelayersofglassandmultiplelayersofPVBinterlayerfilm.Itcanalsobemadeofordinaryglasswithbulletprooffilm.Itcanwithstandtheexplosionofpistols,riflesandevenbombs.Shock.Interroristbombingsincitiesaroundtheworld,glassfragmentsarethemaincauseofpersonalinjury.Whentheexplosionoccurred,theglassfragmentsflewhorizontallylikeraindrops,andcouldevenflyseveralkilometersaway,causingmorethan90%ofthepeopleinjured.Evenifthelaminatedglassisshatteredduringtheexplosion,itcanstillbekeptintheframeintact,whichgreatlyreducesthedamagetopeoplecausedbytheglassfragments.

Themainvarietiesofsafetyglassare:temperedglass,laminatedglass,bulletproofglass,anti-theftglass,fireproofglass,laminatedglass,protectiveglassandfilmedglass.Amongthem,thefilmglasshaspartofthefunctionsoftemperedglass,laminatedglass,bulletproofglass,anti-theftglass,fireproofglass,wireglassandprotectiveglass,andisanewtypeofbuildingmaterial.

Temperedglass

Itistemperedglass.Whentheglassisuniformlyheatedtothesofteningtemperature,theglassismadebyquenchingwithacoolingmediumsuchashigh-speedair.Thereisuniformcompressivestressonthesurfaceoftheglass,whichcanimprovethemechanicalstrengthandthermalshockresistanceoftheglass.Whenairisusedasthecoolingmedium,itiscalledtempering;whenoilandotherliquidsareusedasthecoolingmedium,itiscalledliquidtempering;whenmoltensaltisusedasthecoolingmedium,itiscalledsaltbathtempering.Accordingtothedegreeofrigidityandtheshapeoftheproduct,itcanbedividedintocompletetempered,regionaltempered,semi-tempered,flattemperedandcurvedtempered.Thebendingstrengthoftemperedglassis3to5timeslargerthanthatofuntreatedglass,andcanreach150to250MPa,andthethermalstabilityisincreasedby3to4times.Itcanwithstandsuddenchangesintemperatureof200to250℃,andthereisnosharpnesswhenbroken.Theangularparticleshavelittleharmtothehumanbodyandarethemostwidelyusedsafetyglass.

Duetotheadoptionofnewtemperingprocesses,suchasrollerorair-cushionflattempering;thedevelopmentofnewcoolingmedia,suchasaddingspecialsolidmedia,highlyvolatileliquidstocompressedair,andtheuseofsiliconeoilThemediumandsolidcontactmethod,etc.,greatlyimprovesthecoolingefficiencyofthecoolingmedium,andcantemperthinglassof1.7to3mm,furtherimprovethestrengthoftheglass,andreduceitsownweight.Alsodevelopedglazedtemperedglasswithprintingandsprayingcoloredglaze.

Toughenedglassismainlyusedintheconstructionofdoors,windows,showcases,enclosurestructuresandasdecorativematerials.

Laminatedglass
