Mzere Wowonjezera Filimu wa PVB/SGP Glass Interlayer

Chiyambi cha makhalidwe a zipangizo za SGP ndi PVB
Monga kampani yotchuka padziko lonse yaukadaulo wa mankhwala, DuPont yayambitsa zinthu zingapo zophatikizana ndi magalasi kuti ikwaniritse kukula kwa msika wa magalasi oteteza komanso kufunika kwa miyezo yatsopano yowongolera chitetezo, kulimba, ndi kukongola kwa magalasi. Zogulitsa za DuPont, ukadaulo, ndi machitidwe omaliza owunikira zimakwaniritsa zosowa izi, motero zimalimbikitsa chitukuko cha makampani onse oteteza magalasi.

1. DuPont Butacite® polyvinyl butyral interlayer (PVB) yakhala ikukonzedwanso nthawi zonse m'zaka 67 zapitazi ndipo yakhala chinthu chofunikira kwambiri pa galasi lotetezedwa, kupereka galasi lotetezedwa ndi ubwino wambiri: chitetezo, kupewa kuba ndi kuwononga, kuchepetsa phokoso, kusunga mphamvu ndi kuwala kwa dzuwa. Kuwongolera ndikuletsa kutha ndi kukongola kwa zinthu zopanda chitsulo m'nyumba.

2. DuPont SentryGlas®Plus (SGP) interlayer ndi interlayer yagalasi yokhala ndi laminated yokhala ndi ukadaulo waukulu wopangidwa ndi DuPont. SGP imapitirira ukadaulo womwe ulipo ndipo imakulitsa kwambiri mawonekedwe agalasi yokhala ndi laminated. Mphamvu ya SGP yong'ambika ndi kasanu kuposa ya PVB wamba, ndipo kuuma kwake ndi kasanu kuposa ya PVB wamba. Mphamvu ya SGP, kuwonekera bwino kwambiri, kulimba, kapangidwe kake kambiri komanso kukhazikika kosinthasintha kumapangitsa kuti zikhale zosavuta kuzolowera zofunikira zaposachedwa komanso zovuta kwambiri pamsika wamakono womanga. Poyerekeza ndi galasi wamba, galasi la SGP laminated limatha kusintha magwiridwe antchito agalasi losagonjetseka ndikuchepetsa makulidwe agalasi lokhala ndi laminated mpaka pamlingo winawake.

SGP yapangidwa mwapadera kuti ikwaniritse zosowa za makampani omanga masiku ano. Ili ndi chitetezo chofanana ndi cha PVB, koma imatha kusintha kwambiri kukana kugwedezeka, kukana kuba ndi kukana zipolowe komanso kukana masoka; kuti galasi likhalebe mu chimango, likhoza kukhala lolimba komanso lolimba. Filimu ya SGP interlayer; ndi yoyenera magalasi a padenga, chifukwa ali ndi mphamvu zolimba komanso zofunikira pakuteteza pogwiritsa ntchito komanso pambuyo posweka. Kutentha kwa galasi lokhala ndi laminated kukawonjezeka, limakhala ndi nthawi yogwira ntchito yokhazikika komanso yayitali, komanso kukana nyengo komanso kukhazikika kwa m'mphepete.

● SGP ndi chinthu chooneka ngati viscoelastic chomwe chili ndi mphamvu yokulirapo (kuwirikiza kasanu kuposa filimu ya PVB).
● Kutentha kofunikira kwa galasi ~55°C (kulimba kwake kuwirikiza nthawi 30–100 kuposa filimu ya PVB).
● Galasi lopangidwa ndi SGP ndi lolimba kuposa galasi lopangidwa ndi PVB.
● Galasi lopangidwa ndi laminated la SGP ndi galasi la monolithic la makulidwe ofanana ali ndi mphamvu yofanana yopindika.

Chithunzi 3. Mphamvu Yoyerekeza
Poyerekeza ndi magalasi ena opangidwa ndi laminated interlayer, magalasi opangidwa ndi laminated a SGP ali ndi mphamvu zambiri. Angathe kuchepetsa makulidwe a galasi, makamaka magalasi opangidwa ndi laminated. Ndi othandiza kwambiri pa magalasi opangidwa ndi mfundo.

Chithunzi 4. Kupatuka kofanana
Poyerekeza ndi magalasi ena opangidwa ndi laminated interlayer, magalasi opangidwa ndi laminated a SGP amakhala olimba kwambiri. Amathandiza kuchepetsa makulidwe a magalasi.

Ili ndi mphamvu zambiri komanso modulus yodula, ndi mphamvu zabwino kwambiri zamakanika.
Modulus yodula ya SGP ndi yoposa PVB nthawi 100, ndipo mphamvu ya kung'ambika ndi yoposa kasanu kuposa ya PVB. Pambuyo poti SGP yaikidwa pa lamination, guluu pakati pa zidutswa ziwiri za galasi silimatsetsereka galasi likakanikizidwa, ndipo zidutswa ziwiri za galasi zimagwira ntchito ngati galasi limodzi lokhala ndi makulidwe ofanana. Mwanjira imeneyi, mphamvu yonyamula imakhala yowirikiza kawiri kuposa galasi lodula la PVB lokhala ndi makulidwe ofanana; nthawi yomweyo, pansi pa katundu wofanana ndi makulidwe ofanana, digiri yopindika ya galasi lodula la SGP ndi 1/4 yokha ya galasi lodula la PVB.

● Kukhazikika bwino m'mphepete komanso kugwirizana bwino ndi zomatira zopangidwa ndi kapangidwe kake.
Kukhazikika kwa m'mphepete kumatanthauza kulimba kwa m'mphepete mwa galasi lopaka utoto lomwe limaonekera pamlengalenga. Kupaka utoto wa PVB sikumalimbana ndi chinyezi, ndipo ndikosavuta kutsegula ndikulekanitsa pogwiritsa ntchito nthunzi yamadzi, kotero m'mphepete mwake mumafunika kutsekedwa m'mphepete. Filimu ya SGP ili ndi kukhazikika kwabwino m'mphepete, siikhudzidwa ndi chinyezi, imayamwa pang'ono komanso imayamwa pang'ono, ndipo siidzatseguka kapena kupatukana ikagwiritsidwa ntchito pamikhalidwe yowonekera. Pambuyo pa zaka 12 zoyeserera kuyanjana ndi sealant ndi coating, palibe chomwe chinapezeka.

● Yopanda utoto komanso yowonekera bwino, yosavuta kusintha mtundu, yopepuka kwambiri, chizindikiro cha chikasu pansi pa 1.5.
Filimu ya SGP yokhala ndi laminated ndi yopanda utoto komanso yowala, ndipo imakhala ndi kukana kwabwino kwa nyengo ndipo si yachikasu mosavuta. Kuchuluka kwa chikasu kwa filimu ya SGP ndi kochepera 1.5, pomwe kuchuluka kwa chikasu kwa filimu ya PVB ndi 6 ~ 12. Nthawi yomweyo, filimu ya SGP ikhoza kukhalabe yowonekera bwino pambuyo pa zaka zambiri ikugwiritsidwa ntchito, pomwe filimu wamba ya PVB imakhala yachikasu pang'onopang'ono ikagwiritsidwa ntchito.

● Kuchita bwino kwambiri pachitetezo komanso kuteteza kulowerera kwa galasi litasweka.
Galasi wamba la PVB laminated, makamaka galasi lofewa, likasweka, limapanga kusintha kwakukulu kopindika, ndipo pali chiopsezo chogwa kuchokera pa chidutswa chonse. Galasi likayikidwa mopingasa padenga, chiopsezo chimakhala chachikulu kwambiri. Kukhulupirika kwa galasi la SGP laminated interlayer ndikwabwino, ndipo mphamvu yong'ambika ya filimu ya SGP laminated ndi yowirikiza kasanu kuposa filimu ya PVB laminated. Ngakhale galasi litasweka, filimu ya SGP ikhoza kumamatirabe. Galasi losweka limapanga kapangidwe kakanthawi pambuyo polephera, komwe kali ndi kusintha pang'ono kopindika ndipo kumatha kupirira kuchuluka kwa katundu popanda chidutswa chonse kugwa. Izi zimathandizira kwambiri chitetezo cha galasi.

● Kulimbana bwino ndi nyengo, sikukalamba mosavuta.
Pambuyo pa zaka 12 zoyeserera kukalamba mwachilengedwe ku Florida, kuyesa kofulumira kwa nyengo ku Arizona, kuyesa kowiritsa ndi kuphika, palibe vuto la kutsegulira guluu ndi thovu patatha zaka 12.

● Kumamatira bwino kwambiri ku zitsulo.
Mphamvu ya SGP ndi zitsulo ndi yokwera, monga aluminiyamu, chitsulo, mkuwa. Galasi lopaka utoto lopangidwa ndi SGP ndi waya wachitsulo, mauna ndi mbale zimatha kusintha kwambiri magwiridwe antchito a galasi likasweka, ndipo limakhala ndi mphamvu yolimbana ndi kuwonongeka komanso kulowerera.

Kugwiritsa Ntchito: Galasi lopangidwa ndi filimu ya PVB/SGP limatha kuyamwa mphamvu ya kugwedezeka popanda kupanga zidutswa zosweka. Limagwiritsidwa ntchito kwambiri pagalasi lopangidwa ndi laminated yamagalimoto, galasi losagonjetseka ndi zipolopolo, galasi losagonjetseka ndi mawu, galasi la photovoltaic, galasi lamitundu, ndi zina zotero. Kuwonjezera pa magwiridwe antchito otetezeka, lilinso ndi anti-ultraviolet yabwino kwambiri, kutchinjiriza mawu, kuwongolera kuwala, kusunga kutentha, kutchinjiriza kutentha, kukana kugwedezeka ndi zina. Ndi chinthu chabwino kwambiri chopangidwa ndi galasi lotetezeka.

Filimu yomatira yagalasi ya SGP (filimu yapakati ya ionic): mawonekedwe odulira a filimu ya ionic SGP ndi ochulukirapo kuposa PVB, mphamvu yong'ambika ndi yochepera 50 kuposa PVB, ndipo mphamvu yonyamula ndi yochepera 2 kuposa galasi lomatira la PVB. Pansi pa katundu ndi makulidwe omwewo, kupindika kwa galasi lomatira la SGP ndi 1/4 yokha yagalasi lomatira la PVB. Poyerekeza ndi galasi lomatira lopangidwa ndi PVB, magwiridwe antchito a galasi lomatira lopangidwa ndi filimu ya SGP ndi apamwamba kwambiri.
Kugwiritsa ntchito: Galasi la denga, nyumba yomanga magalasi, msewu wa matabwa agalasi, khoma lalitali lakunja, khoma la nsalu yagalasi, ndi zina zotero.
