Laminated iav yog ib qho iav uas feem ntau siv hauv kev ua vaj tsev iav, uas tseem hu ua kev thaj yeeb iav. Laminated iav yog tsim los ntawm ntau txheej iav, ntxiv rau cov iav, qhov seem yog cov qhaub cij hauv nruab nrab ntawm iav, feem ntau muaj peb hom qhaub cij: EVA, PVB, SGP.

PVB Sandwich Trust yog ib lub npe paub ntau dua. PVB kuj yog cov khoom siv sandwich uas siv hauv cov iav vaj tsev thiab cov iav tsheb tam sim no.

Cov txheej txheem khaws cia thiab ua cov txheej txheem ntawm PVB interlayer yog qhov nyuaj dua li EVA, thiab qhov yuav tsum tau ua rau kub thiab av noo siab dua. PVB kev thov kev ntsuas kub ntawm 18 ℃ -23 ℃, txheeb ze av noo tswj ntawm 18-23%, PVB ua raws li 0.4% -0.6% cov ntsiab lus noo noo, tom qab preheating dov lossis lub tshuab nqus tsev yog siv autoclade kom tsis txhob muaj cua sov thiab siab, autoclade kub: 120-130 ℃, siab: 1.0-1.3MPa, sijhawm: 30-60 feeb. PVB cov neeg siv khoom xav tau txog 1 lab nyiaj, thiab muaj qee qhov nyuaj rau cov lag luam me. Nyob rau hauv ob peb xyoos dhau los, tsuas yog rau txawv teb chaws Dupont, Shou Nuo, dej thiab lwm yam manufacturers noj, domestic PVB yog tsuas yog siv cov ntaub ntawv kom tsis txhob ua lwm yam, tab sis qhov zoo stability tsis zoo heev. Nyob rau hauv xyoo tas los no, domestic PVB cov neeg siv khoom lag luam kuj tau maj mam tsim.

PVB muaj kev nyab xeeb zoo, suab rwb thaiv tsev, pob tshab thiab tshuaj tiv thaiv hluav taws xob, tab sis PVB dej tsis zoo, thiab nws yooj yim qhib rau hauv qhov chaw ntub dej ntev.
cov
EVA sawv cev rau ethylene-vinyl acetate copolymer. Vim nws cov dej tsis muaj zog thiab corrosion kuj, nws yog dav siv nyob rau hauv ntim zaj duab xis, haumxeeb zaj duab xis, ua npuas ncauj khau ntaub, kub yaj nplaum, hlau thiab cable thiab cov khoom ua si, thiab lwm yam, Tuam Tshoj feem ntau siv EVA raws li ib tug ntaub ntawv.
cov
EVA kuj tseem siv los ua cov qhaub cij ntawm cov iav laminated, thiab nws cov nqi ua haujlwm siab. Piv nrog PVB thiab SGP, EVA muaj kev ua haujlwm zoo dua thiab qis dua ablation, thiab tuaj yeem ua tiav thaum qhov kub nce mus txog 110 ℃. Nws tag nrho cov khoom siv rau cov neeg siv khoom xav tau txog 100,000 yuan.

Cov yeeb yaj kiab ntawm EVA muaj kev ua haujlwm zoo, uas tuaj yeem nres cov txheej txheem ntawm cov hlau clamping thiab dov hauv txheej zaj duab xis los tsim cov iav zoo nkauj nrog cov qauv thiab cov qauv. EVA muaj cov dej tsis zoo, tab sis nws yog resistant rau tshuaj rays, thiab ntev lub hnub raug yog ib qho yooj yim mus daj thiab dub, yog li nws yog tsuas yog siv rau sab hauv tsev muab faib.

SGP stands rau ionic intermediate membrane (Sentryglass Plus), uas yog cov khoom siv ua haujlwm siab tsim los ntawm DuPont. Nws cov kev ua tau zoo yog manifested nyob rau hauv:
cov
1, zoo heev mechanical zog, siab zog. Nyob rau hauv tib lub thickness, lub peev xwm ntawm SGP sandwich yog ob zaug ntawm PVB. Nyob rau hauv tib lub load thiab thickness, khoov deflection ntawm SGP laminated iav yog ib lub quarter ntawm PVB.
cov
2. Lub zog tsim kua muag. Nyob rau tib lub thickness, lub zog tearing ntawm PVB nplaum zaj duab xis yog 5 npaug ntawm PVB, thiab nws tseem tuaj yeem ua rau cov iav hauv qab qhov muag, tsis ua rau tag nrho cov iav poob.
cov
3, muaj zog stability, ntub tsis kam. SGP zaj duab xis tsis muaj xim thiab pob tshab, tom qab lub hnub ntev thiab los nag, tiv taus cov tshuaj rays, tsis yooj yim rau daj, yellowing coefficient <1.5, tab sis yellowing coefficient ntawm PVB sandwich zaj duab xis yog 6 ~ 12. Yog li ntawd, SGP yog tus hlub ntawm ultra-dawb laminated iav.
cov
Txawm hais tias cov txheej txheem noj ntawm SGP yog ze rau ntawm PVB, tus nqi davhlau ya nyob twg yog siab, yog li daim ntawv thov hauv Suav teb tsis muaj ntau, thiab kev paub txog nws tsawg.
