PVB/SGP Glass Interlayer Film Extrusion Line

Chidziwitso cha zinthu za SGP ndi PVB
Monga kampani yotchuka padziko lonse lapansi yaukadaulo wamakina, DuPont yakhazikitsa zinthu zingapo zopangira magalasi kuti zikwaniritse kukula kwa msika wamagalasi otetezera komanso kufunikira kwa miyezo yatsopano yopititsira patsogolo chitetezo, kulimba, komanso kukongola kwa galasi.Zogulitsa za DuPont, matekinoloje ndi njira zowunikira zomaliza zimakwaniritsa zofunikira izi, motero zimalimbikitsa chitukuko chamakampani onse agalasi otetezedwa.

1. DuPont Butacite® polyvinyl butyral interlayer (PVB) yakhala ikuwongoleredwa mosalekeza m'zaka 67 zapitazi ndipo yakhala chinthu chofunikira kwambiri pachitetezo cha magalasi otetezedwa, opatsa magalasi okhala ndi zabwino zambiri: chitetezo, anti-kuba ndi kuwononga, phokoso. kuchepetsa, kupulumutsa mphamvu ndi kuwala kwa dzuwa Kuwongolera ndi kupewa kuzirala ndi kukongola kwa zinthu zamkati zopanda chitsulo.

2. DuPont SentryGlas®Plus (SGP) interlayer ndi laminated galasi interlayer yokhala ndi luso lamakono lopangidwa ndi DuPont.SGP imapitilira ukadaulo womwe ulipo ndikukulitsa kwambiri mawonekedwe agalasi laminated.Mphamvu yong'ambika ya SGP ndi kuwirikiza kasanu kuposa ya PVB wamba, ndipo kuuma kwake ndi nthawi 100 kuposa PVB wamba.Kulimba kwamphamvu kwa SGP, kuwonekera kwakukulu, kulimba, zomanga zingapo ndikuyika kosinthika kumapangitsa kuti zikhale zosavuta kuzolowera zomwe zaposachedwa komanso zolimba kwambiri pamsika wamakono wamakono.Poyerekeza ndi galasi wamba laminated, galasi laminated la SGP limatha kupititsa patsogolo magwiridwe antchito agalasi lopanda zipolopolo ndikuchepetsa makulidwe a galasi laminated pamlingo wina.

SGP idapangidwa kuti ikwaniritse zosowa zamabizinesi amakono.Lili ndi chitetezo chofanana chophwanyika ndi kusungirako zidutswa monga PVB, koma zimatha kusintha kwambiri kukana, kutsutsa-kuba ndi ntchito zotsutsana ndi zipolowe komanso kukana masoka a galasi lachitetezo;kuti galasi likhale lolimba mu chimango, likhoza kukhala lolimba komanso lamphamvu.SGP interlayer filimu;ndiyoyenera magalasi a denga, chifukwa imakhala ndi mphamvu zolimba komanso zofunikira zopatuka pachitetezo chogwiritsidwa ntchito komanso pambuyo pakusweka.Pamene kutentha kwa galasi laminated kumawonjezeka, kumakhala ndi moyo wokhazikika komanso wautali wautumiki, komanso kukana kwambiri kwa nyengo ndi kukhazikika kwa m'mphepete.

● SGP ndi chinthu chopangidwa ndi viscoelastic chokhala ndi mphamvu zong'ambika kwambiri (nthawi 5 kuposa filimu ya PVB).
● Galasi kutentha kwambiri ~ 55 ° C (kuuma 30-100 nthawi ya filimu ya PVB).
● Galasi laminated la SGP ndi lolimba kuposa galasi la PVB laminated.
● Galasi lamwala la SGP ndi galasi la monolithic la makulidwe omwewo ali ndi mphamvu yofanana yofanana.

Chithunzi 3. Mphamvu Zachibale
Poyerekeza ndi magalasi ena a interlayer laminated, galasi laminated SGP lidzakhala ndi mphamvu zambiri.Ikhoza kuchepetsa makulidwe a galasi, makamaka kwa galasi lakuda laminated.Zothandiza makamaka pagalasi lothandizira mfundo.

Chithunzi 4. Kupatuka kwachibale
Poyerekeza ndi magalasi ena a interlayer laminated, galasi laminated SGP lidzakhala lolimba kwambiri.Amathandiza kuchepetsa makulidwe a galasi

Ali ndi mphamvu zambiri komanso kumeta ubweya modulus, makina abwino kwambiri.
Makina ometa ubweya wa SGP ndi nthawi 100 kuposa PVB, ndipo mphamvu yong'ambika ndi yokwera kasanu kuposa ya PVB.SGP itapangidwa laminated, guluu wosanjikiza pakati pa magalasi awiriwo sangasunthike pamene galasi likugogomezedwa, ndipo zidutswa ziwiri za galasi zimagwira ntchito ngati galasi limodzi lokhala ndi makulidwe ofanana.Mwa njira iyi, mphamvu yobereka ndi kawiri ya galasi la PVB laminated la makulidwe ofanana;nthawi yomweyo, pansi pa chikhalidwe cha katundu wofanana ndi makulidwe ofanana, digiri yopindika ya galasi laminated SGP ndi 1/4 yokha ya galasi la PVB laminated.

● Kukhazikika bwino m'mphepete komanso kumagwirizana bwino ndi zomatira zamapangidwe.
Kukhazikika kwa m'mphepete kumatanthawuza kukhazikika kwa m'mphepete mwa galasi laminated lomwe limawonekera mumlengalenga.PVB lamination sikugonjetsedwa ndi chinyezi, ndipo n'zosavuta kutsegula ndi kupatukana pansi pa zochitika za nthunzi yamadzi, kotero kuti m'mphepete mwake mumayenera kutsekedwa m'mphepete.Filimu ya SGP ili ndi kukhazikika kwa m'mphepete mwabwino, sikukhudzidwa ndi chinyezi, imakhala yochepa kwambiri komanso imayamwa, ndipo sidzatsegula kapena kupatukana ikagwiritsidwa ntchito powonekera.Pambuyo pa zaka 12 zoyeserera zosindikizira ndi zokutira, palibe choyipa chomwe chidapezeka.

● Zopanda utoto komanso zowoneka bwino, zosavuta kusintha mtundu, zowoneka bwino kwambiri, index ya yellowness pansi pa 1.5.
Kanema wa SGP laminated palokha ndi wopanda utoto komanso wowoneka bwino, ndipo ali ndi kukana kwanyengo yabwino ndipo sikophweka kukhala wachikasu.Chokwanira chachikasu cha filimu ya SGP ndi yochepera 1.5, pomwe chikasu cha filimu ya PVB ndi 6 ~ 12.Nthawi yomweyo, filimu ya SGP imatha kukhalabe yowonekera pakatha zaka zambiri ikugwiritsidwa ntchito, pomwe filimu wamba ya PVB interlayer pang'onopang'ono imakhala yachikasu kwambiri ikagwiritsidwa ntchito.

● Kuchita bwino kwachitetezo ndi ntchito zotsutsana ndi zowonongeka pambuyo pa kusweka kwa galasi.
Wamba PVB galasi laminated, makamaka kupsya magalasi laminated, galasi litasweka, limatulutsa kupindika kwakukulu, ndipo pamakhala ngozi yogwa kuchokera pachidutswa chonsecho.Galasiyo ikayikidwa moyang'anizana padenga, chiopsezo chimakhala chokulirapo.Umphumphu wa galasi lopangidwa ndi SGP interlayer laminated ndi labwino, ndipo mphamvu ya misozi ya SGP laminated film ndi 5 nthawi ya filimu ya PVB laminated.Ngakhale galasi litasweka, filimu ya SGP ikhoza kumamatirabe Galasi losweka limapanga dongosolo lakanthawi kochepa pambuyo polephera, lomwe limakhala ndi mapindikidwe ang'onoang'ono opindika ndipo amatha kupirira kuchuluka kwa katundu popanda chidutswa chonsecho kugwa.Izi zimathandizira kwambiri chitetezo cha galasi.

● Kutha kupirira nyengo, sikuchedwa kukalamba.
Pambuyo pazaka 12 zakuyesa kukalamba kwachilengedwe ku Florida, kuyesa kwanyengo ku Arizona, kuyesa kowiritsa ndi kuphika, palibe vuto lotsegula ndi kuchita thovu patatha zaka 12.

● Kumamatira kwabwino kuzitsulo.
Mphamvu zomangira za SGP ndi zitsulo ndizokwera, monga aluminiyamu, chitsulo, mkuwa.Galasi lopangidwa ndi SGP ndi waya wachitsulo, mauna ndi mbale zimatha kupititsa patsogolo magwiridwe antchito agalasi pambuyo posweka, ndipo zimakhala ndi zotsutsana ndi zowonongeka komanso zotsutsana ndi kulowerera.

Ntchito: Galasi lopangidwa ndi filimu ya PVB/SGP limatha kuyamwa mphamvu zake popanda kupanga zidutswa zosweka. Amagwiritsidwa ntchito kwambiri pamagalasi opangidwa ndi magalimoto, magalasi otsimikizira zipolopolo, galasi lotsimikizira mawu, magalasi a photovoltaic, galasi lamtundu, ndi zina zambiri. ntchito, ilinso ndi anti ultraviolet yabwino, kutsekereza mawu, kuwongolera kuwala, kuteteza kutentha, kutsekereza kutentha, kukana kugwedezeka ndi zina.Ndi abwino chitetezo galasi gulu zakuthupi.

Filimu yomatira magalasi a SGP (filimu yapakatikati ya ionic): mawonekedwe ometa ubweya wa filimu ya ionic SGP ndi nthawi zopitilira 50 kuposa PVB, mphamvu ya misozi ndi nthawi 5 kuposa PVB, ndipo mphamvu yonyamula ndi nthawi 2 kuposa magalasi opangidwa ndi PVB.Pansi pa katundu ndi makulidwe omwewo, kupindika kwa galasi lopangidwa ndi SGP ndi 1/4 yokha ya galasi la PVB laminated.Poyerekeza ndi galasi laminated lopangidwa ndi PVB, ntchito ya galasi laminated yopangidwa ndi filimu ya SGP ndiyopambana kwambiri.
Ntchito: Magalasi a denga, nyumba yomanga magalasi, msewu wamatabwa wagalasi, khoma lakunja lalitali, khoma lotchinga magalasi, etc.
