Liphanele tsa sandwich li sebelisoa haholo kahong ka lebaka la litšobotsi tsa tsona tse ntle tsa ho thibela mocheso, matla a sebopeho le bonolo ba ho li kenya. Thepa ea mantlha ea liphanele tsena e ka etsoa ka lifomo tse fapaneng, joalo ka foam ea polyurethane, boto ea lifaha tsa polystyrene, kapa khalase ea foam. Har'a tsena, foam ea polyurethane hangata ke khetho e ratoang ka lebaka la litšobotsi tsa eona tse phahameng tsa ho thibela mocheso le ho tenyetseha ha tsona. Ho utloisisa karolo ea li-catalyst tsa polyurethane tlhahisong ea liphanele tsa sandwich ho bohlokoa bakeng sa bahlahisi ba ikemiselitseng ho ntlafatsa ts'ebetso le bokhoni.
Foam ea Polyurethane ka har'a Liphanele tsa Sandwich
Foam ea polyurethane (PU) ke thepa ea bohlokoa kahong ea liphanele tsa sandwich. E fana ka tšireletso e ntle ea mocheso, thepa e bobebe le botsitso ba sebopeho.Li-catalyst tsa ho etsa foam ea PU, tse kangMXC-T, MXC-C15, jj.Tlhahiso ea foam ea PU e kenyelletsa karabelo ea lik'hemik'hale pakeng tsa li-polyol le li-isocyanate, tse thusoang ke li-catalyst tsa polyurethane. Li-catalyst tsena li bohlokoa ho laoleng sekhahla sa karabelo, ho netefatsa boleng ba foam, le ho fihlela litšobotsi tse lakatsehang tse kang ho teteana, ho tiea le ho hanyetsa mocheso.
Karolo ea Li-Catalyst tsa Polyurethane
1. Taolo ea Karabelo: Li-catalyst tsa polyurethane li laola lebelo la karabelo ea lik'hemik'hale lipakeng tsa li-polyol le li-isocyanate. Ka ho laola karabelo ena, bahlahisi ba ka hlahisa foam e nang le boleng le litšobotsi tse tsitsitseng. Li-catalyst li thusa ho fihlela tekano e nepahetseng pakeng tsa ho tiea le ho tenyetseha ha foam, ho netefatsa hore e fihlela litlhoko tse itseng bakeng sa lits'ebetso tsa pane ea sandwich.
2. Litšobotsi tse Ntlafalitsoeng tsa Foam: Tšebeliso ea li-catalyst e ntlafatsa litšobotsi tsa 'mele tsa foam ea PU. Li-catalyst li ka etsoa ho ntlafatsa litšobotsi tse kang matla a ho hatella, ho khomarela thepa e shebaneng le eona, le ho tsamaisa mocheso. Ho iketsetsa hona ho netefatsa hore foam e fihlela litekanyetso tse thata tse hlokahalang bakeng sa thepa ea kaho, e fanang ka ho tšoarella le ho phela nako e telele ho liphanele tsa sandwich.
3. Bokgoni ba Tlhahiso: Di-catalyst di bapala karolo ya bohlokwa ho ntlafatseng tshebetso ya tlhahiso. Di nolofalletsa dinako tse potlakileng tsa karabelo mme di fokotsa potoloho yohle ya tlhahiso, e leng se lebisang ho bokgoni bo eketsehileng le katleho ya ditjeo. Sena se bohlokwa haholo tlhahisong e kgolo, moo botsitso le lebelo di leng bohlokwa bakeng sa ho fihlela ditlhoko tsa mmaraka.
Mefuta ea Foam ka har'a Sandwich Panels
Leha foam ea polyurethane e le khetho e tsebahalang, liphanele tsa sandwich li ka etsoa ka ho sebelisa mefuta e meng ea thepa ea foam:
1. Boto ea Lifaha tsa Polystyrene (EPS): Boto ea lifaha tsa polystyrene e atolositsoeng ke thepa e 'ngoe ea mantlha e tloaelehileng bakeng sa liphanele tsa sandwich. E fana ka tšireletso e ntle ea mocheso 'me e bobebe. Leha ho le joalo, ha e fane ka boemo bo tšoanang ba botšepehi ba sebopeho le foam ea PU.
2. Khalase ea Foam: Khalase ea foam ke thepa e thata, e bobebe e nang le thepa e ntle ea ho thibela mocheso le ho hanyetsa mongobo le mollo. Hangata e sebelisoa lits'ebetsong moo ho hanyetsa mollo le ho tšoarella ho leng bohlokoa haholo.
Qetello
Li-catalyst tsa polyurethane li bohlokoa tlhahisong ea liphanele tsa sandwich tsa boleng bo holimo, haholo-holo tse sebelisang foam ea polyurethane e le thepa ea mantlha. Ka ho laola ts'ebetso ea karabelo, ho ntlafatsa thepa ea foam, le ho ntlafatsa katleho ea tlhahiso, li-catalyst tsena li thusa bahlahisi ho theha liphanele tse fihlelang litlhoko tse matla tsa kaho ea sejoale-joale. Ho utloisisa tšimo ea ts'ebeliso ea li-catalyst tsa polyurethane ho nolofalletsa khetho e betere ea thepa le ntlafatso ea ts'ebetso, qetellong ho kenya letsoho nts'etsopele ea thepa e ntle ea kaho.
