Li-catalyst tsa polyurethane li bapala karolo ea bohlokoa tlhahisong ea liphanele tsa sandwich tsa polyurethane, tse sebelisoang haholo liindastering tse fapaneng ka lebaka la thepa ea tsona e ntle ea ho thibela ho ruruha, matla a sebopeho le tlhaho e bobebe. Ho utloisisa ts'ebeliso ea li-catalyst tsena ho ka fana ka temohisiso mabapi le ts'ebetso ea tlhahiso le melemo ea ho sebelisa liphanele tsa sandwich tsa polyurethane.
Sehlopha sa Sandwich ke eng?
Hangata phanele ea sandwich e na le mekhahlelo e meraro: khubu e tlase e entsoeng ka foam e thata ea polyurethane le maqephe a mabeli a kantle a fanang ka tšehetso le tšireletso ea sebopeho. Thepa ea mantlha, foam e thata ea polyurethane, e khethoa ka lebaka la litšobotsi tsa eona tse phahameng tsa ho thibela mocheso, tlhaho e bobebe, le matla a mechini. Maqephe a ka ntle a ka etsoa ka thepa e fapaneng, ho kenyeletsoa PPGI (tšepe e koahetsoeng esale pele), PPGL (tšepe e entsoeng ka aluminiyumu ea zinki e koahetsoeng esale pele), maqephe a aluminium, kapa li-foil tsa pampiri. Maqephe ana a etsoa kapa a kobeha ho latela litlhoko tsa mochini o etsang roller, ho etsa phanele e tiileng le e koahetsoeng.
Karolo ea Li-Catalyst tsa Polyurethane
Li-catalyst tsa polyurethane tse kangMXC-Tle MXC-BDMA li bohlokoa tlhahisong ea foam e thata ea polyurethane, e leng eona e etsang motheo oa liphanele tsa sandwich. Li-catalyst tsena li nolofalletsa liketso tsa lik'hemik'hale lipakeng tsa li-precursor tsa polyurethane, li nolofalletsa ho thehoa ha polymer e boima ba limolek'hule. Ka tloaelo, likarolo tse 'ne kapa ho feta tsa mokelikeli tse nang le li-precursor tsa polyurethane lia lekanngoa le ho kopanngoa nakong ea mohato oa ts'ebetso ho hlahisa foam ea polyurethane. Karolo ea li-catalyst ke ho potlakisa liketso tsena, ho netefatsa ho thehoa ha foam ka katleho le ka taolo.
Tshebetso ea Tlhahiso
Tlhahiso ea liphanele tsa sandwich tsa polyurethane e kenyelletsa mekhahlelo e 'maloa:
1. Ho lekanya le ho Kopanya: Dikarolo tsa mokelikeli tse nang le di-precursor tsa polyurethane di lekanngwa le ho kopanngwa ka nepo. Mohato ona ke wa bohlokwa bakeng sa ho fihlella dibopeho tse lakatsehang tsa foam.
2. Karabelo ea ho Fofola: Likarolo tse tsoakiloeng li feta karabelong ea ho fofola, e thusoang ke li-catalyst MXC-T le MXC-BDMA. Li-catalyst li netefatsa hore karabelo e etsahala ka lebelo le letle, e hlahisang khubu ea fofo e tsitsitseng le ea boleng bo holimo.
3. Lamination: Karolo e ka hare ea foam e koahetsoe pakeng tsa maqephe a mabeli a ka ntle, a entsoeng kapa a kobehileng ho latela litlhoko tsa mochini o etsang roller.
4. Ho phekola: Phanele ea sandwich e kopantsoeng e phekoloa ho lumella foam ho atoloha ka botlalo le ho khomarela maqephe a ka ntle, e leng se fellang ka sebopeho se matla le se tsitsitseng.
Melemo ea Liphanele tsa Sandwich tsa Polyurethane
1. Ho Thibela Mocheso: Foam e tiileng ea polyurethane e fana ka ho thibela mocheso hantle, e leng se etsang hore liphanele tsa sandwich li be ntle bakeng sa lits'ebetso moo taolo ea mocheso e leng ea bohlokoa.
2. Matla a Sebopeho: Motsoako oa motheo o tiileng oa foam le maqephe a kantle a tšoarellang o fana ka matla a phahameng a sebopeho, e leng se etsang hore liphanele li lokele lits'ebetso tsa ho jara mojaro.
3. E bobebe: Ho sa tsotellehe matla a tsona, diphanele tsa sandwich tsa polyurethane di bobebe, e leng se fokotsang ditjeo tsa dipalangwang le tsa ho kenya.
4. Ho feto-fetoha ha maemo: Diphanele tsena di ka sebediswa mesebetsing e fapaneng, ho kenyeletswa kaho ya meaho, diyuniti tsa sehatsetsi le dipalangwang.
Qetello
Li-catalyst tsa polyurethane tse kang MXC-T leMXC-BDMAli bohlokoa tlhahisong ea liphanele tsa sandwich tsa polyurethane tsa boleng bo holimo. Liphanele tsena li fana ka melemo e mengata, ho kenyeletsoa le ho thibela mocheso hantle, matla a sebopeho le ho tenyetseha. Ho utloisisa karolo ea li-catalyst ts'ebetsong ea tlhahiso ho totobatsa bohlokoa ba liketso tse nepahetseng tsa lik'hemik'hale tlhahisong ea thepa e fihlelang maemo a indasteri le litlhoko tsa ts'ebeliso. Jwalo ka mofani oa li-catalyst tsa polyurethane, re netefatsa hore lihlahisoa tsa rona li kenya letsoho tlhahisong e sebetsang hantle le e sebetsang ea liphanele tsa sandwich tsa polyurethane, ho tšehetsa liindasteri tse fapaneng ho fihlelleng lipheo tsa tsona tsa ho thibela mocheso le tsa sebopeho.
