Iglasi elaminethiweyo yiglasi esetyenziswa kakhulu kwicandelo leglasi yokwakha, eyaziwa ngokuba yiglasi yoxolo. Iglasi elaminethiweyo yenziwe ngamaleya amaninzi eglasi, ukongeza kwiglasi, okuseleyo yisandwich ephakathi kweglasi, ngokuqhelekileyo kukho iintlobo ezintathu zesandwich: i-EVA, i-PVB, i-SGP.
I-PVB sandwich Trust yenye yamagama aqhelekileyo. I-PVB ikwayindlela eqhelekileyo yokwenziwa kwesandwich esetyenziswa kwiglasi yokwakha kunye neglasi yeemoto okwangoku.
Inkqubo yokugcina kunye nendlela yokucubungula ye-PVB interlayer iyinkimbinkimbi kune-EVA, kwaye iimfuno zobushushu kunye nokufuma ziphezulu. Isicelo sokucubungula i-PVB silawula ubushushu phakathi kwe-18℃-23℃, ulawulo lokufuma oluhambelanayo kwi-18-23%, i-PVB inamathela kumxholo wokufuma we-0.4%-0.6%, emva kokufudumeza kwangaphambili inkqubo yokuqengqeleka okanye yokuvasa kukusetyenziswa kwe-autoclade ukuyeka ukugcinwa kobushushu 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, ngokuyintloko kwiDupont yangaphandle, iShou Nuo, amanzi kunye nabanye abavelisi, i-PVB yasekhaya isetyenziswa kakhulu idatha ukuze iyeke ukusetyenzwa kwesibini, kodwa uzinzo lomgangatho alulunganga kakhulu. Kwiminyaka yakutshanje, abavelisi babathengi be-PVB basekhaya nabo baphuhla kancinci kancinci.
I-PVB inokhuseleko oluhle, i-insulation yesandi, i-transparent kunye ne-chemical radiation resistance, kodwa ukumelana namanzi e-PVB akulunganga, kwaye kulula ukuyivula kwindawo efumileyo ixesha elide.
I-EVA imele i-ethylene-vinyl acetate copolymer. Ngenxa yokumelana kwayo namanzi kunye nokugqwala kwayo, isetyenziswa kakhulu kwifilimu yokupakisha, ifilimu yeshedi esebenzayo, izinto zezihlangu zefoam, iglu eshushu enyibilikayo, ucingo kunye nentambo kunye nezinto zokudlala, njl.njl., iTshayina idla ngokusebenzisa i-EVA njengolwazi olulodwa.
I-EVA ikwasetyenziswa njengesandwich yeglasi elaminethiweyo, kwaye ukusebenza kwayo ngexabiso eliphezulu. Xa ithelekiswa ne-PVB kunye ne-SGP, i-EVA inomsebenzi ongcono kunye nobushushu obuphantsi bokukhupha, kwaye inokucutshungulwa xa ubushushu bufikelela malunga ne-110℃. Iseti yayo epheleleyo yezixhobo zabathengi ifuna malunga ne-100,000 yuan.
Ifilimu ye-EVA inomsebenzi omhle, onokumisa inkqubo yokubethelwa kwentambo nokuqengqeleka kumaleko wefilimu ukuze kwenziwe iglasi entle yokuhombisa eneepateni kunye neepateni. I-EVA inokumelana kakuhle namanzi, kodwa ayichatshazelwa yimitha yeekhemikhali, kwaye ukuvezwa lilanga ixesha elide kulula ukuba kube mthubi namnyama, ngoko ke isetyenziselwa ikakhulu ukwahlulahlula ngaphakathi.
I-SGP imele i-ionic intermediate membrane (Sentryglass Plus), eyi-sandwich material esebenza kakhulu eyenziwe yiDuPont. Ukusebenza kwayo okuphezulu kubonakala ku:
1, iipropati ezibalaseleyo zoomatshini, amandla aphezulu. Phantsi kobukhulu obufanayo, amandla okuthwala esandwich ye-SGP aphindwe kabini kunalawo e-PVB. Phantsi komthwalo nobukhulu obufanayo, ukugoba kweglasi ye-SGP ene-laminated yikota enye yaleyo ye-PVB.
2. Amandla okukrazula. Kubukhulu obufanayo, amandla okukrazula efilimu yokuncamathelisa yePVB aphindwe kahlanu kunalawo ePVB, kwaye inokuncamatheliswa kwiglasi phantsi kwemeko yokukrazula, ngaphandle kokwenza iglasi yonke iwe.
3, uzinzo oluqinileyo, ukumelana nokumanzi. Ifilimu ye-SGP ayinambala kwaye ayibonakali, emva kwelanga nemvula ixesha elide, imelana nemisebe yeekhemikhali, ayilulanga ukuyityheli, i-coefficient etyheli < 1.5, kodwa i-coefficient etyheli yefilimu yesandwich ye-PVB yi-6 ~ 12. Ke ngoko, i-SGP yeyona ithandwayo yeglasi emhlophe kakhulu.
Nangona inkqubo yokusetyenziswa kwe-SGP iphantse yafana neye-PVB, ixabiso lesiphelo liphezulu, ngoko ke ukusetyenziswa kwayo eTshayina akuxhaphakanga kangako, kwaye ulwazi lwayo luphantsi.
