Khalase ea laminated e entsoe ka likarolo tse ngata tsa khalase, ho phaella ho khalase, tse ling kaofela ke sandwich e bohareng ba khalase, hangata ho na le mefuta e meraro ea sandwich: EVA, PVB, SGP.
.
PVB sandwich Trust ke e 'ngoe ea mabitso a tsebahalang haholo. PVB hape ke lisebelisoa tse tloaelehileng tsa sandwich tse sebelisoang likhalaseng tsa meralo le likhalase tsa likoloi hajoale.

Mokhoa oa ho boloka le mokhoa oa ho sebetsa oa PVB interlayer o rarahane ho feta EVA, 'me litlhoko tsa mocheso le mongobo li phahame. PVB ts'ebetso ea kopo ea taolo ea mocheso pakeng tsa 18 ℃-23 ℃, taolo ea mongobo e lekanyelitsoeng ho 18-23%, PVB e khomarela 0.4% -0.6% ea mongobo, ka mor'a hore ho be le mocheso oa ho futhumatsa kapa oa ho hloekisa ke tšebeliso ea autoclade ho emisa ho boloka mocheso le khatello, mocheso oa autoclade: 120-130 ℃, khatello: 1.0-1.3MPa, nako: 30-60mins. Thepa ea bareki ea PVB e hloka chelete e ka bang limilione tse 1, 'me ho na le bothata bo itseng bakeng sa likhoebo tse nyane. Lilemong tse 'maloa tse fetileng, haholo-holo ho Dupont e tsoang linaheng tse ling, Shou Nuo, metsi le lihlahisoa tse ling tse sebelisoang, PVB ea malapeng e sebelisoa haholo-holo ho thibela ts'ebetso ea bobeli, empa botsitso ba boleng ha bo botle haholo. Lilemong tsa morao tjena, baetsi ba bareki ba PVB ba malapeng le bona ba ntse ba tsoela pele butle-butle.
.
PVB e na le tšireletseho e ntle, ho thibela molumo, ho pepeseha le lik'hemik'hale tse hanyetsanang le mahlaseli a kotsi, empa ho hanyetsa metsi a PVB ha ho molemo, 'me ho bonolo ho bula tikolohong e mongobo nako e telele.
.
EVA e emetse ethylene-vinyl acetate copolymer. Ka lebaka la ho hanyetsa metsi a matla le ho hanyetsa kutu, e sebelisoa haholo ho paka filimi, filimi e tšolotsoeng e sebetsang, lisebelisoa tsa lieta tsa foam, sekhomaretsi se chesang se qhibilihisang, terata le cable le lintho tsa ho bapala, joalo-joalo, Chaena hangata e sebelisa EVA e le boitsebiso bo le bong feela.
.
EVA e boetse e sebelisoa e le sandwich ea khalase ea laminated, 'me ts'ebetso ea eona ea litšenyehelo e phahame. 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 110 ℃. Sesebelisoa sa eona se felletseng sa lisebelisoa tsa bareki se 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 koala le ho roala ka har'a sethala sa filimi ho etsa likhalase tse ntle tse khabisitsoeng ka lipaterone le lipaterone. EVA e na le khanyetso e ntle ea metsi, empa e hanana le mahlaseli a lik'hemik'hale, 'me ho pepeseha ha letsatsi nako e telele ho bonolo ho ba mosehla le o motšo, kahoo e sebelisoa haholo-holo bakeng sa karohano ea ka hare.
.
SGP e emetse ionic intermediate membrane (Sentryglass Plus), e leng thepa ea sandwich e sebetsang hantle haholo e ntlafalitsoeng ke DuPont. Tshebetso ea eona e phahameng e bonahala ka:
.
1, thepa e babatsehang ea mochine, matla a phahameng. Tlas'a botenya bo tšoanang, matla a ho jara a sandwich ea SGP e mena habeli ea PVB. Tlas'a mojaro le botenya bo tšoanang, ho kheloha ha khalase ea laminated ea SGP ke kotara ea PVB.
.
2. Matla a tabolang. Ka botenya bo ts'oanang, matla a ho qhaqha a filimi ea sekhomaretsi ea PVB ke makhetlo a 5 a PVB, 'me e ka boela ea khomarela khalase tlas'a boemo ba ho taboha, ntle le ho etsa hore khalase eohle e theohe.
.
3, botsitso bo matla, ho hanyetsa metsi. Filimi ea SGP ha e na 'mala ebile e hlakile, ka mor'a nako e telele ea letsatsi le pula, e hanyetsa mahlaseli a lik'hemik'hale, ha ho bonolo ho mosehla, coefficient e mosehla <1.5, empa coefficient e mosehla ea filimi ea sandwich ea PVB ke 6 ~ 12. Ka hona, SGP ke moratuoa oa khalase ea laminated e bosoeu haholo.
.
Le hoja ts'ebetso ea tšebeliso ea SGP e haufi le ea PVB, theko ea theko e phahameng e phahame, kahoo kopo ea Chaena ha e tloaelehe haholo, 'me tlhokomeliso ea eona e tlaase.
