I-Glas annealing yinkqubo yonyango lobushushu ukunciphisa okanye ukuphelisa uxinzelelo olusisigxina oluveliswa kwinkqubo yokwenza iglasi okanye ukusebenza okushushu kunye nokuphucula ukusebenza kweglasi.Phantse zonke iimveliso zeglasi kufuneka zifakwe i-annealed ngaphandle kwefayibha yeglasi kunye nodonga olubhityileyo iimveliso ezincinci ezingenanto.
I-annealing yeglasi kukufudumeza kwakhona iimveliso zeglasi kunye noxinzelelo olusisigxina kwiqondo lokushisa apho amasuntswana angaphakathi kweglasi angakwazi ukuhamba, kwaye asebenzise ukufuduka kweengqungquthela ukusabalalisa uxinzelelo (olubizwa ngokuba yi-stress relaxation) ukuphelisa okanye ukunciphisa uxinzelelo olusisigxina.Izinga lokuphumla koxinzelelo lixhomekeke kubushushu beglasi, kokukhona iqondo lobushushu liphezulu, kokukhona liyakhawuleza izinga lokuphumla.Ke ngoko, uluhlu olufanelekileyo lweqondo lobushushu lisisitshixo sokufumana umgangatho olungileyo weglasi.
Ukufakwa kweglasi yeglasi ikakhulu kubhekisa kwinkqubo yokubeka iglasi kwindawo yokutshisa ionti ixesha elide elaneleyo lokupholisa kuluhlu lweqondo lobushushu okanye ngesantya esicothayo, ukuze uxinzelelo olusisigxina nolwexeshana olungaphaya koluhlu oluvumelekileyo lungabi saveliswa, okanye uxinzelelo lwe-thermal olwenziwe kwiglasi luyancitshiswa okanye lupheliswe kangangoko kunokwenzeka.Kwimveliso yeglasi ye-microbeads xa eyona ngongoma ibalulekileyo i-glass annealing, iimveliso zeglasi ekubunjweni kobushushu obuphezulu, kwinkqubo yokupholisa iya kuvelisa amanqanaba ahlukeneyo oxinzelelo lwe-thermal, oku kuhanjiswa okungalinganiyo koxinzelelo lwe-thermal, kuya kunciphisa kakhulu amandla omatshini kunye nokuzinza kwe-thermal. yemveliso, kwangaxeshanye ekwandiseni iglasi, ukuxinana, optical constants zinefuthe, ukuze imveliso ayikwazi ukufikelela injongo yokusetyenziswa.
Injongo ye-annealing yeemveliso zeglasi kukunciphisa okanye ukunciphisa uxinzelelo olushiyekileyo kwiimveliso, kunye ne-optical inhomogeneity, kunye nokuzinzisa isakhiwo sangaphakathi seglasi.Ulwakhiwo lwangaphakathi lweemveliso zeglasi ngaphandle kwe-annealing aluzange lube kwisimo esizinzileyo, njengokutshintsha kobuninzi beglasi emva kokuqhawula.(Ubuninzi beemveliso zeglasi emva kokuba i-annealing bukhulu kunoxinano ngaphambi kokuba kufakwe i-annealing) Uxinzelelo lweemveliso zeglasi lunokwahlulwa lube luxinzelelo lwe-thermal, uxinzelelo lwesakhiwo kunye noxinzelelo lomatshini.
Ke ngoko, uluhlu olufanelekileyo lweqondo lobushushu lisisitshixo sokufumana umgangatho olungileyo weglasi.Iphezulu kunomlinganiselo weqondo lokushisa, iglasi iya kuthambisa i-deformation: ezantsi kweqondo lokushisa elifunekayo, isakhiwo seglasi sinokuqwalaselwa njengesigxina, i-particle yangaphakathi ayinakuhamba, ayikwazi ukusabalalisa okanye ukuphelisa uxinzelelo.
Iglasi igcinwa kuluhlu lobushushu be-annealing kangangexesha elithile ukwenzela ukuba uxinzelelo lwangaphambili olusisigxina lususwe.Emva koko, iglasi kufuneka ipholile ngesantya esifanelekileyo sokupholisa ukuqinisekisa ukuba akukho xinzelelo olutsha olusisigxina lwenziwa kwiglasi.Ukuba izinga lokupholisa likhawuleza kakhulu, kukho ithuba lokuvelisa kwakhona uxinzelelo olusisigxina, oluqinisekiswa linqanaba lokupholisa elicothayo kwinkqubo yokucoca.Inqanaba lokupholisa elicothayo kufuneka liqhubeke ukuya kobonana bushushu busezantsi bokuthomalalisa.
Xa iglasi ipholile ngaphantsi kweqondo lobushushu le-annealing, kuphela uxinzelelo lwexeshana oluya kuveliswa ukugcina ixesha kunye nokunciphisa ubude bomgca wemveliso, kodwa kwakhona kufuneka ulawule ukupholisa okuthile ngokukhawuleza, kunokwenza uxinzelelo lwexeshana lube lukhulu kunamandla okugqibela. iglasi ngokwayo kwaye ikhokelela ekuqhumeni kwemveliso.
