Ikirahuri cyanduye ni ikirahuri gikunze gukoreshwa mubirahuri byubatswe, bizwi kandi nkikirahure cyamahoro. Ikirahuri cyanduye kigizwe nibice byinshi byikirahure, usibye ikirahure, ahasigaye ni sandwich hagati yikirahure, mubisanzwe hariho ubwoko butatu bwa sandwich: EVA, PVB, SGP.
?
PVB sandwich Icyizere nimwe mumazina azwi. PVB kandi nibikoresho bisanzwe bya sandwich bikoreshwa mubirahuri byubatswe hamwe nikirahure cyimodoka.
?
Uburyo bwo kubika no gutunganya uburyo bwa PVB interlayer buragoye kuruta EVA, kandi ibisabwa kubushyuhe nubushuhe ni byinshi. Gutunganya PVB bisaba kugenzura ubushyuhe hagati ya 18 ℃ -23 ℃, kugenzura ubushuhe bugereranije kuri 18-23%, PVB yubahiriza 0,4% -0,6% yubushyuhe, nyuma yo gushyushya ibizunguruka cyangwa vacuum ni ugukoresha autoclade kugirango uhagarike kubika ubushyuhe nigitutu, ubushyuhe bwa autoclade: 120-130 ℃, igitutu: 1.0-1.3MPa, igihe: 30-60min. Ibikoresho byabaguzi ba PVB bikenera amafaranga agera kuri miliyoni, kandi hariho ingorane runaka kubucuruzi buciriritse. Mu myaka mike ishize, cyane cyane kubanyamahanga Dupont, Shou Nuo, amazi nabandi bakora ibicuruzwa, PVB yo murugo ikoreshwa cyane cyane kugirango ihagarike gutunganya kabiri, ariko ireme ryiza ntabwo ari ryiza cyane. Mu myaka yashize, abakoresha PVB bo murugo nabo batera imbere buhoro buhoro.
?
PVB ifite umutekano mwiza, kubika amajwi, gukorera mu mucyo no kurwanya imishwarara y’imiti, ariko kurwanya PVB ntabwo ari byiza, kandi biroroshye gufungura ahantu h’ubushuhe igihe kirekire.
?
EVA isobanura Ethylene-vinyl acetate copolymer. Kubera imbaraga zikomeye zo kurwanya amazi no kurwanya ruswa, ikoreshwa cyane muri firime yo gupakira, firime ikora yamashanyarazi, ibikoresho byinkweto zifuro, ibyuma bishushe bishyushye, insinga ninsinga n ibikinisho, nibindi, Ubushinwa bukoresha EVA nkamakuru yonyine.
?
EVA nayo ikoreshwa nka sandwich yikirahure cyanduye, kandi imikorere yacyo ni myinshi. Ugereranije na PVB na SGP, EVA ifite ibikorwa byiza nubushyuhe bwo hasi, kandi birashobora gutunganywa mugihe ubushyuhe bugeze kuri 110 ℃. Ibikoresho byuzuye byabaguzi bikenera amafaranga 100.000.
?
Filime ya EVA ifite ibikorwa byiza, bishobora guhagarika inzira yo gufunga insinga no kuzunguruka murwego rwa firime kugirango ikore ibirahuri byiza byo gushushanya bifite ishusho. EVA ifite amazi meza, ariko irwanya imirasire yimiti, kandi izuba ryigihe kirekire ryoroshye kumuhondo numukara, kubwibyo rikoreshwa cyane cyane mubice byo murugo.
?
SGP isobanura ionic intermediate membrane (Sentryglass Plus), ni ibikoresho bya sandwich bikora cyane byakozwe na DuPont. Imikorere yacyo yo hejuru igaragara muri:
?
1, ibikoresho byiza bya mashini, imbaraga nyinshi. Munsi yubunini bumwe, ubushobozi bwo gutwara SGP sandwich bwikubye kabiri ubwa PVB. Munsi yumutwaro umwe nubunini, kugoreka kwa SGP kumirahuri ni kimwe cya kane cyi PVB.
?
2. Kurira imbaraga. Muri ubwo bunini, imbaraga zo gutanyagura za firime ya PVB yikubye inshuro 5 za PVB, kandi irashobora no gufatirwa ku kirahure mu gihe cyo kurira, bitabaye ngombwa ko ikirahure cyose gitonyanga.
?
3, gushikama gukomeye, kwihanganira amazi. Filime ya SGP idafite ibara kandi ibonerana, nyuma yizuba nimvura byigihe kirekire, irwanya imirasire yimiti, ntibyoroshye kumuhondo, coefficient yumuhondo <1.5, ariko coefficient yumuhondo ya PVB sandwich ya firime ni 6 ~ 12. Kubwibyo, SGP nikundira ibirahuri byera byera cyane.
?
Nubwo inzira yo gukoresha SGP yegereye iya PVB, igiciro cyanyuma ni kinini, bityo rero mubushinwa ntibisanzwe cyane, kandi kubimenya ni bike.
