Kugereranya imiterere ya EVA, PVB na SGP ya firime y'ikirahure ifite laminated

Ikirahure cyabugenewe ni ikirahure gikoreshwa cyane mu bijyanye n'ibirahure by'ubwubatsi, kizwi kandi ku izina ry'ikirahure cy'amahoro. Ikirahure cyabugenewe kigizwe n'ibirahure byinshi, uretse ikirahure, igisigaye ni sandwich iri hagati mu kirahure, ubusanzwe hariho ubwoko butatu bwa sandwich: EVA, PVB, SGP.
Ese?
Ishyirahamwe rya PVB sandwich Trust ni rimwe mu mazina azwi cyane. PVB ni ibikoresho bisanzwe bikoreshwa mu birahuri by’ubwubatsi n’ibirahuri by’imodoka muri iki gihe.
Ese?
Uburyo bwo kubika no gutunganya PVB interlayer bugoye kurusha EVA, kandi ibisabwa ku bushyuhe n'ubushuhe biri hejuru. Gutunganya PVB bisaba kugenzura ubushyuhe buri hagati ya 18℃-23℃, kugenzura ubushuhe buri kuri 18-23%, PVB ikurikiza ubushuhe buri hagati ya 0.4%-0.6%, nyuma yo gushyushya, inzira yo gushyushya cyangwa kuvanga ni ugukoresha autoclade kugira ngo ubushyuhe bukomeze kubungabungwa n'umuvuduko, ubushyuhe bwa autoclade: 120-130℃, umuvuduko: 1.0-1.3MPa, igihe: iminota 30-60. Ibikoresho bya PVB bikenera amafaranga agera kuri miliyoni 1, kandi hari ingorane ku bucuruzi buto. Mu myaka mike ishize, ahanini ikoreshwa mu mahanga ya Dupont, Shou Nuo, amazi n'abandi bakora, PVB yo mu rugo ikoreshwa cyane cyane kugira ngo ihagarike gutunganya kwa kabiri, ariko ubuziranenge ntibumeze neza cyane. Mu myaka ya vuba aha, abakora PVB bo mu rugo nabo barimo gutera imbere buhoro buhoro.
Ese?
PVB ifite umutekano mwiza, ifite uburinzi bw'urusaku, ifite ubushobozi bwo kuyungurura no kurwanya imirasire ya shimi, ariko PVB ifite ubushobozi bwo kurwanya amazi ntabwo ari nziza, kandi yoroshye kuyifungura ahantu hatose igihe kirekire.
Ese?
EVA ihagarariye ethylene-vinyl acetate copolymer. Kubera ko irwanya amazi cyane kandi irwanya ingese, ikoreshwa cyane mu gupfunyika, mu gupfunyika ibyuma, mu bikoresho by'inkweto za foam, mu gufunga bishyushye, insinga n'insinga n'ibindi, Ubushinwa busanzwe bukoresha EVA nk'amakuru yonyine.
Ese?
EVA ikoreshwa kandi nk'umugati w'ibirahure bya laminated, kandi igiciro cyayo kiri hejuru. Ugereranyije na PVB na SGP, EVA ifite imikorere myiza kandi ubushyuhe bwo kugabanya ubushyuhe, kandi ishobora gutunganywa iyo ubushyuhe bugeze kuri dogere 110. Ibikoresho byayo byose bikenera amayuni agera ku 100.000.
Ese?
Agace ka EVA gafite imikorere myiza, gashobora guhagarika inzira yo gufunga no kuzunguruka insinga mu gice cya firime kugira ngo hakorwe ikirahuri cyiza gishushanyijeho imitako gifite imiterere n'imiterere. EVA ifite ubushobozi bwo kwirinda amazi, ariko irwanya imirasire ya shimi, kandi izuba rimara igihe kirekire rishobora kuba umuhondo n'umukara, bityo ikoreshwa cyane cyane mu gutandukanya imbere mu nzu.
Ese?
SGP isobanura ionic intermediate membrane (Sentryglass Plus), ikaba ari sandwich ikora neza cyane yakozwe na DuPont. Imikorere yayo igaragara muri:
Ese?
1, imiterere myiza ya mekanike, imbaraga nyinshi. Mu gihe cy'ubugari bumwe, ubushobozi bwo gutwara bwa sandwich ya SGP bungana kabiri n'ubwa PVB. Mu gihe cy'umutwaro n'ubugari bumwe, ikirahure cya SGP cyashyizwemo laminate ni kimwe cya kane cy'icya PVB.
Ese?
2. Ingufu zo gucika. Ku bunini bumwe, imbaraga zo gucika za PVB adhesive film zikubye inshuro 5 ugereranyije na PVB, kandi ishobora no gushyirwa ku kirahuri munsi y’aho cyacitse, idatumye ikirahuri cyose gicika.
Ese?
3, gukomera cyane, kwihangana gukomeye. Filimi ya SGP nta ibara ifite kandi ibonerana, nyuma y'izuba n'imvura igihe kirekire, irwanya imirasire ya shimi, ntabwo byoroshye kuyihindura umuhondo, ihinduka umuhondo < 1.5, ariko ihinduka umuhondo rya filimi ya sandwich ya PVB ni 6 ~ 12. Kubwibyo, SGP niyo ikundwa cyane n'ikirahure cy'umweru cyane.
Ese?
Nubwo uburyo bwo gukoresha SGP buri hafi ya PVB, igiciro cyayo kiri hejuru, bityo ikoreshwa mu Bushinwa ntirikunze kugaragara cyane, kandi abantu benshi ntibabizi.
