Kuyerekeza kwa EVA, PVB ndi SGP katundu wa galasi laminated filimu

Galasi yopangidwa ndi laminated ndi galasi yomwe imagwiritsidwa ntchito kwambiri pamagalasi omangamanga, omwe amadziwikanso kuti galasi lamtendere. Galasi laminated limapangidwa ndi zigawo zingapo za galasi, kuwonjezera pa galasi, ena onse ndi sangweji pakati pa galasi, kawirikawiri pali mitundu itatu ya masangweji: EVA, PVB, SGP.
pa
PVB sangweji Trust ndi amodzi mwa mayina odziwika bwino. PVB ndizomwe zimagwiritsidwa ntchito pamagalasi omanga ndi magalasi amagalimoto pakadali pano.

Njira yosungirako ndi njira yopangira PVB interlayer ndizovuta kwambiri kuposa EVA, ndipo zofunikira pa kutentha ndi chinyezi ndizokwera. PVB processing pempho kutentha ulamuliro pakati 18 ℃-23 ℃, ulamuliro chinyezi wachibale pa 18-23%, PVB kutsatira 0.4% -0.6% chinyezi okhutira, pambuyo preheating anagubuduza kapena zingalowe ndondomeko ndi ntchito autoclade kusiya kuteteza kutentha ndi kuthamanga, kutentha kwa autoclade: 120-130 ℃, kuthamanga: 1.0-1.3MPa, nthawi: 30-60 min. Zida zogulira za PVB zimafunikira ndalama pafupifupi 1 miliyoni, ndipo pali zovuta zina zamabizinesi ang'onoang'ono. M'zaka zingapo zapitazo, makamaka yachilendo Dupont, Shou Nuo, kumwa madzi ndi opanga ena, PVB zoweta makamaka zobwezerezedwanso deta kusiya processing yachiwiri, koma bata khalidwe si zabwino kwambiri. M'zaka zaposachedwapa, zoweta PVB ogula opanga nawo pang'onopang'ono kukhala.
pa
PVB ili ndi chitetezo chabwino, kutsekemera kwa mawu, kuwonekera ndi kukana kwa mankhwala a radiation, koma kukana kwa madzi a PVB sikuli kwabwino, ndipo ndikosavuta kutsegulira m'malo onyowa kwa nthawi yayitali.
pa
EVA imayimira ethylene-vinyl acetate copolymer. Chifukwa cha kukana kwamadzi kwamphamvu komanso kukana kwa dzimbiri, imagwiritsidwa ntchito kwambiri pakuyika filimu, filimu yokhetsa ntchito, zinthu za nsapato za thovu, zomatira zotentha zosungunuka, waya ndi chingwe ndi zidole, ndi zina zambiri, China nthawi zambiri imagwiritsa ntchito EVA ngati chidziwitso chokha.
pa
EVA imagwiritsidwanso ntchito ngati masangweji a galasi laminated, ndipo mtengo wake ndi wapamwamba. Poyerekeza ndi PVB ndi SGP, EVA imakhala ndi ntchito yabwinoko komanso kutentha kwapang'onopang'ono, ndipo imatha kusinthidwa kutentha kukafika pafupifupi 110 ℃. Zida zake zonse zogulira zimafunikira pafupifupi 100,000 yuan.
pa
Kanema wa EVA ali ndi ntchito yabwino, yomwe imatha kuyimitsa njira yolumikizira waya ndikugudubuza mufilimuyo kuti ipange magalasi okongola okongoletsera okhala ndi mawonekedwe ndi mawonekedwe. EVA imakhala ndi madzi abwino, koma imagonjetsedwa ndi kuwala kwa mankhwala, ndipo kutentha kwa dzuwa kwa nthawi yaitali kumakhala kosavuta kukhala kwachikasu ndi kwakuda, kotero kumagwiritsidwa ntchito makamaka kugawanitsa m'nyumba.
pa
SGP imayimira ionic intermediate membrane (Sentryglass Plus), yomwe ndi sangweji yogwira ntchito kwambiri yopangidwa ndi DuPont. Kuchita kwake kwakukulu kumawonetsedwa mu:
pa
1, zabwino makina katundu, mkulu mphamvu. Pansi pa makulidwe omwewo, mphamvu yonyamula ya sangweji ya SGP ndi yowirikiza kawiri ya PVB. Pansi pa katundu ndi makulidwe omwewo, kupindika kwa galasi la SGP laminated ndi gawo limodzi mwa magawo atatu a PVB.
pa
2. Kung'amba mphamvu. Pa makulidwe omwewo, mphamvu yong'ambika ya filimu yomatira ya PVB ndi nthawi 5 kuposa ya PVB, ndipo imathanso kumangirizidwa pagalasi pansi pa kung'ambika, popanda kugwetsa galasi lonse.
pa
3, kukhazikika kwamphamvu, kukana konyowa. Kanema wa SGP ndi wopanda mtundu komanso wowonekera, pambuyo pa dzuwa ndi mvula kwanthawi yayitali, kusagwirizana ndi kuwala kwamankhwala, kosavuta kukhala wachikasu, kokwanira kwachikasu <1.5, koma chikasu cha filimu ya PVB masangweji ndi 6 ~ 12. Chifukwa chake, SGP ndiye wokondedwa wagalasi loyera kwambiri.
pa
Ngakhale njira yogwiritsira ntchito SGP ili pafupi ndi ya PVB, mtengo wamtengo wapatali ndi wokwera kwambiri, kotero kuti ntchito ku China siili yofala kwambiri, ndipo kuzindikira kwake kuli kochepa.
