Iav laminated yog ib hom iav siv ntau hauv kev tsim vaj tsev, uas tseem hu ua iav kev thaj yeeb. Iav laminated yog tsim los ntawm ntau txheej iav, ntxiv rau iav, qhov seem yog lub sandwich hauv nruab nrab ntawm iav, feem ntau muaj peb hom sandwich: EVA, PVB, SGP.
PVB sandwich Trust yog ib lub npe uas neeg paub zoo tshaj plaws. PVB kuj yog ib yam khoom siv sandwich uas siv rau hauv cov iav vaj tse thiab cov iav tsheb tam sim no.
Cov txheej txheem khaws cia thiab txoj kev ua cov PVB interlayer nyuaj dua li EVA, thiab qhov yuav tsum tau ua rau kub thiab av noo ntau dua. Kev ua PVB thov kom tswj qhov kub ntawm 18 ℃ -23 ℃, tswj qhov av noo ntawm 18-23%, PVB ua raws li 0.4% -0.6% cov dej noo, tom qab ua ntej cua sov dov lossis nqus tsev yog siv autoclade kom tiv thaiv kev khaws cia kub thiab siab, autoclade kub: 120-130 ℃, siab: 1.0-1.3MPa, lub sijhawm: 30-60 feeb. PVB cov khoom siv rau cov neeg siv khoom xav tau txog 1 lab nyiaj, thiab muaj qee qhov teeb meem rau cov lag luam me. Ob peb xyoos dhau los, feem ntau yog rau Dupont txawv teb chaws, Shou Nuo, dej thiab lwm yam tuam txhab tsim khoom noj, PVB hauv tsev feem ntau yog rov ua dua cov ntaub ntawv kom tiv thaiv kev ua tiav theem ob, tab sis qhov zoo tsis zoo heev. Nyob rau xyoo tas los no, cov tuam txhab tsim khoom siv PVB hauv tsev kuj maj mam tsim kho.
PVB muaj kev nyab xeeb zoo, suab rwb thaiv tsev, pob tshab thiab tiv taus tshuaj lom neeg, tab sis PVB tsis tiv taus dej zoo, thiab nws yooj yim qhib rau hauv qhov chaw noo noo ntev.
EVA yog lub npe luv rau ethylene-vinyl acetate copolymer. Vim nws muaj zog tiv taus dej thiab tiv taus xeb, nws yog siv dav hauv cov zaj duab xis ntim khoom, cov zaj duab xis ua haujlwm, cov khoom siv khau ua npuas ncauj, cov nplaum kub yaj, hlau thiab cable thiab cov khoom ua si, thiab lwm yam. Feem ntau, Tuam Tshoj siv EVA ua cov ntaub ntawv nkaus xwb.
EVA kuj tseem siv ua lub sandwich ntawm laminated iav, thiab nws cov nqi ua haujlwm siab. Piv nrog PVB thiab SGP, EVA muaj kev ua haujlwm zoo dua thiab qhov kub ablation qis dua, thiab tuaj yeem ua tiav thaum qhov kub txog li 110 ℃. Nws 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 tiv thaiv cov txheej txheem ntawm cov hlau clamping thiab dov hauv cov txheej zaj duab xis los tsim cov iav zoo nkauj nrog cov qauv thiab cov qauv. EVA muaj cov dej tsis kam zoo, tab sis nws tiv taus cov tshuaj lom neeg, thiab lub hnub ci ntev ntev yog yooj yim daj thiab dub, yog li nws feem ntau yog siv rau kev faib sab hauv tsev.
SGP sawv cev rau ionic intermediate membrane (Sentryglass Plus), uas yog cov khoom siv sandwich ua tau zoo uas DuPont tsim. Nws qhov kev ua tau zoo yog pom tseeb hauv:
1, cov khoom siv kho tshuab zoo heev, lub zog siab. Nyob rau hauv tib lub thickness, lub peev xwm ntawm SGP sandwich yog ob npaug ntawm PVB. Nyob rau hauv tib lub load thiab thickness, lub bending deflection ntawm SGP laminated iav yog ib feem plaub ntawm PVB.
2. Lub zog rhuav. Ntawm tib lub tuab, lub zog rhuav ntawm PVB nplaum zaj duab xis yog 5 npaug ntawm PVB, thiab nws kuj tuaj yeem nplaum rau lub iav hauv qab qhov mob rhuav, yam tsis ua rau tag nrho lub iav poob.
3, ruaj khov, tiv taus dej noo. Zaj duab xis SGP tsis muaj xim thiab pob tshab, tom qab lub hnub thiab nag ntev, tiv taus cov tshuaj lom neeg, tsis yooj yim daj, tus lej daj <1.5, tab sis tus lej daj ntawm PVB sandwich zaj duab xis yog 6 ~ 12. Yog li ntawd, SGP yog qhov nyiam ntawm cov iav laminated ultra-dawb.
Txawm hais tias cov txheej txheem siv ntawm SGP ze rau PVB, tus nqi davhlau ya nyob twg siab, yog li daim ntawv thov hauv Suav teb tsis tshua muaj, thiab kev paub txog nws qis.
