Khalase e nang le laminated ke khalase e sebelisoang haholo lefapheng la khalase ea meralo, e tsejoang hape e le khalase ea khotso. Khalase e nang le laminated e entsoe ka mekhahlelo e mengata ea khalase, ho phaella khalaseng, karolo e setseng ke sandwich e bohareng ba khalase, hangata ho na le mefuta e meraro ea sandwich: EVA, PVB, SGP.
.
Sandwich ea PVB Trust ke e 'ngoe ea mabitso a tsebahalang haholo. PVB hape ke thepa e tloaelehileng ea sandwich e sebelisoang khalaseng ea meralo le khalaseng ea likoloi hajoale.
.
Mokhoa oa polokelo le mokhoa oa ho sebetsana le PVB interlayer o rarahane ho feta EVA, 'me litlhoko tsa mocheso le mongobo li phahame. Ts'ebetso ea PVB e kopa taolo ea mocheso pakeng tsa 18℃-23℃, taolo ea mongobo e lekanyelitsoeng ho 18-23%, PVB e khomarela mongobo oa 0.4%-0.6%, kamora ho futhumatsa pele ts'ebetso ea ho phutholla kapa ea vacuum ke ts'ebeliso ea autoclade ho emisa ho boloka mocheso le khatello, mocheso oa autoclade: 120-130℃, khatello: 1.0-1.3MPa, nako: 30-60min. Lisebelisoa tsa bareki ba PVB li hloka chelete e ka bang milione, 'me ho na le bothata bo itseng bakeng sa likhoebo tse nyane. Lilemong tse 'maloa tse fetileng, haholo-holo ho Dupont ea kantle ho naha, Shou Nuo, tšebeliso ea metsi le bahlahisi ba bang, PVB ea malapeng e sebelisoa haholo ho emisa ts'ebetso ea bobeli, empa botsitso ba boleng ha bo botle haholo. Lilemong tsa morao tjena, bahlahisi ba bareki ba PVB ba malapeng le bona ba ntse ba tsoela pele butle-butle.
.
PVB e na le polokeho e ntle, e thibelang modumo, e pepeneneng le e hanyetsang mahlaseli a dikhemikhale, empa ho hanyetsa metsi a PVB ha ho hotle, mme ho bonolo ho e bula tikolohong e mongobo nako e telele.
.
EVA e emetse ethylene-vinyl acetate copolymer. Ka lebaka la ho hanyetsa metsi le ho hanyetsa mafome, e sebelisoa haholo filiming ea liphutheloana, filiming ea shed e sebetsang, thepa ea lieta tsa foam, sekhomaretsi se chesang se qhibilihang, terata le cable le lintho tsa ho bapala, jj., Chaena hangata e sebelisa EVA e le tlhahisoleseling e le 'ngoe feela.
.
EVA e boetse e sebelisoa e le sandwich ea khalase e laminated, 'me ts'ebetso ea eona ea litšenyehelo e holimo. Ha e bapisoa le PVB le SGP, EVA e na le ts'ebetso e betere le mocheso o tlase oa ablation, 'me e ka sebetsoa ha mocheso o fihla ho hoo e ka bang 110℃. Sete ea eona e felletseng ea lisebelisoa tsa bareki e hloka li-yuan tse ka bang 100,000.
.
Filimi ea EVA e na le ts'ebetso e ntle, e ka emisang ts'ebetso ea ho khomarela ka terata le ho phutholoha ka har'a lera la filimi ho etsa khalase e ntle e khabisitsoeng ka lipaterone le lipaterone. EVA e na le khanyetso e ntle ea metsi, empa e hanela mahlaseli a lik'hemik'hale, 'me ho pepesehela letsatsi nako e telele ho bonolo ho ba mosehla le o motšo, kahoo e sebelisoa haholo bakeng sa karohano ea ka tlung.
.
SGP e emetse lera la ionic intermediate membrane (Sentryglass Plus), e leng thepa ea sandwich e sebetsang hantle e ntlafalitsoeng ke DuPont. Tshebetso ea eona e phahameng e bonahala ka:
.
1, thepa e ntle haholo ea mechini, matla a phahameng. Tlas'a botenya bo tšoanang, bokhoni ba ho jara ba sandwich ea SGP bo habeli ho feta ba PVB. Tlas'a mojaro le botenya bo tšoanang, ho kobeha ha khalase e nang le laminated ea SGP ke kotara ea PVB.
.
2. Matla a ho tabola. Ka botenya bo tšoanang, matla a ho tabola a filimi ea sekhomaretsi ea PVB a feta a PVB ka makhetlo a 5, 'me e ka boela ea khomaretsoa khalaseng tlas'a boemo ba ho tabola, ntle le ho etsa hore khalase eohle e oele.
.
3, botsitso bo matla, ho hanyetsa metsi. Filimi ea SGP ha e na 'mala ebile e bonaletsa, ka mor'a letsatsi le pula ea nako e telele, e hanela mahlaseli a lik'hemik'hale, ha e bonolo ho e etsa mosehla, coefficient ea ho ba mosehla < 1.5, empa coefficient ea ho ba mosehla ea filimi ea sandwich ea PVB ke 6 ~ 12. Ka hona, SGP ke khabane ea khalase e tšoeu haholo e nang le laminated.
.
Leha ts'ebetso ea tšebeliso ea SGP e batla e tšoana le ea PVB, theko ea ho qetela e holimo, kahoo ts'ebeliso Chaena ha e atile haholo, 'me tlhokomeliso ea eona e tlase.
