Iglasi elayitiweyo yiglasi esetyenziswa ngokuqhelekileyo kwindawo yeglasi yokwakha, eyaziwa ngokuba yiglasi yoxolo. Iglasi elayitiweyo yenziwe ngamacandelo amaninzi eglasi, ukongeza kwiglasi, intsalela yisandwich embindini weglasi, ngokuqhelekileyo kukho iintlobo ezintathu zesandwich: EVA, PVB, SGP.
PVB isangweji Trust lelinye lamagama aqhelekileyo. I-PVB ikwayinto eqhelekileyo yesandwich esetyenziswa kwiglasi yoyilo kunye neglasi yemoto okwangoku.
Inkqubo yokugcina kunye nendlela yokucubungula ye-PVB interlayer inzima kakhulu kune-EVA, kwaye iimfuno zokushisa kunye nomswakama ziphezulu. PVB processing isicelo ulawulo lobushushu phakathi 18℃-23℃, ulawulo ukufuma isalamane kwi-18-23%, PVB abambelele 0.4% -0.6% isiqulatho sokufuma, emva preheating rolling okanye inkqubo vacuum kukusetyenziswa autoclade ukumisa ukugcinwa ubushushu kunye noxinzelelo, Ubushushu be-autoclade: 120-130 ℃, uxinzelelo: 1.0-1.3MPa, ixesha: 30-60min. Izixhobo zabathengi be-PVB zifuna malunga ne-1 yezigidi zemali, kwaye kukho ubunzima obuthile kumashishini amancinci. Kwiminyaka embalwa edlulileyo, ikakhulu kwi-Dupont yangaphandle, iShou Nuo, ukusetyenziswa kwamanzi kunye nabanye abavelisi, i-PVB yasekhaya ubukhulu becala iphinda isetyenziswe kwakhona idatha yokuyeka ukusetyenzwa kwesibini, kodwa uzinzo lomgangatho aluhle kakhulu. Kwiminyaka yakutshanje, abavelisi abathengi be-PVB basekhaya nabo bakhula ngokuthe ngcembe.
I-PVB inokhuseleko oluhle, ukugquma kwesandi, ukungafihli kunye nokumelana nemichiza yemitha, kodwa ukuxhathisa kwamanzi kwe-PVB akulunganga, kwaye kulula ukuyivula kwindawo efumileyo ixesha elide.
I-EVA imele i-ethylene-vinyl acetate copolymer. Ngenxa yokunganyangeki kwayo okuqinileyo kwamanzi kunye nokuxhathisa ukubola, isetyenziswa ngokubanzi kwifilimu yokupakisha, ifilimu esebenzayo, ifilimu ye-shed shed, imathiriyeli yezicathulo ze-foam, i-adhesive eshushu enyibilikayo, ucingo kunye nentambo kunye neethoyi, njl., i-China idla ngokusebenzisa i-EVA njengolwazi kuphela.
I-EVA ikwasetyenziswa njengesandwich yeglasi elaminethiweyo, kwaye ukusebenza kwayo kweendleko kuphezulu. Xa kuthelekiswa ne-PVB kunye ne-SGP, i-EVA inomsebenzi ongcono kunye nobushushu obuphantsi bokukhupha umoya, kwaye inokusetyenzwa xa ubushushu bufikelela malunga ne-110 ℃. Iseti yayo epheleleyo yezixhobo zabathengi ifuna malunga ne-yuan eyi-100,000.
Ifilimu ye-EVA inomsebenzi omhle, onokumisa inkqubo yokuqhawula ucingo kunye nokuqengqeleka kwinqanaba lefilimu ukwenza iglasi yokuhlobisa enhle kunye neepateni kunye neepatheni. I-EVA inokumelana kakuhle namanzi, kodwa iyamelana nemitha yekhemikhali, kwaye ukukhanya kwelanga ixesha elide kulula ukutyheli kunye nomnyama, ngoko ke isetyenziselwa ulwahlulo lwangaphakathi.
I-SGP imele i-ionic intermediate membrane (Sentryglass Plus), eyimathiriyeli yesandwich esebenza kakhulu ephuhliswe yiDuPont. Ukusebenza kwayo okuphezulu kubonakaliswa ku:
I-1, iipropathi ezigqwesileyo zoomatshini, amandla aphezulu. Ngaphantsi kobukhulu obufanayo, umthamo wokuthwala wesandwich ye-SGP uphindwe kabini kune-PVB. Ngaphantsi komthwalo kunye nobukhulu obufanayo, ukugoba kweglasi ye-SGP elaminethiweyo yikota enye yePVB.
2. Ukukrazula amandla. Ngobunzima obufanayo, amandla okukrazula kwefilimu yokunamathela ye-PVB ngamaxesha angama-5 kwi-PVB, kwaye inokuphinda ifakwe kwiglasi phantsi kwemeko yokukrazula, ngaphandle kokwenza iglasi yonke iwise.
I-3, ukuzinza okuqinileyo, ukuxhathisa okumanzi. Ifilimu ye-SGP ayinambala kwaye iyabonakala, emva kwexesha elide lelanga kunye nemvula, ukumelana nemitha yekhemikhali, akulula ukutyheli, i-yellowing coefficient <1.5, kodwa i-yellowing coefficient yefilimu ye-sandwich ye-PVB yi-6 ~ 12. Ke ngoko, i-SGP sisithandwa seglasi emhlophe eqaqambileyo.
Nangona inkqubo yokusetyenziswa kwe-SGP isondele kwi-PVB, ixabiso le-terminal liphezulu, ngoko ke isicelo e-China asiqhelekanga kakhulu, kwaye ukuqonda kwayo kuphantsi.
