Diphanele tsa sandwich ke karolo ea bohlokoa ea kaho ea sejoale-joale, li fana ka litharollo tse sebetsang bakeng sa ho thibela mocheso, ho thibela molumo le matla a sebopeho. Li entsoe ka karolo e bobebe ea motheo e pakeng tsa likarolo tse peli tse tšesaane tsa kantle, liphanele tsena li fetohile thepa ea kaho e tloaelehileng ho pholletsa le liindasteri tse kang kaho, sehatsetsing le lipalangoang. Karolo eo li-catalyst tsa polyurethane li e bapalang tlhahisong ea liphanele tsa sandwich e ama boleng, ts'ebetso le katleho ea litšenyehelo tsa sehlahisoa sa ho qetela.
Sehloohong sena, re hlahloba tsebo ea indasteri ea liphanele tsa sandwich, re buisana ka hore na li etsoa joang, 'me re hlahloba karolo ea bohlokoa eo li-catalyst tsa polyurethane li e bapalang tlhahisong ea liphanele tsa sandwich.
Liphanele tsa Sandwich ke eng?
Liphanele tsa sandwich ke thepa e kopantsoeng e entsoeng esale pele e nang le mekhahlelo e meraro e meholo:
Lisebelisoa tsa mantlha – Ka tlwaelo, thepa e bobebe e sireletsang mocheso jwalo ka foam ya polyurethane, foam ya polyisocyanurate (PIR), kapa boya ba diminerale.
Mealo e 'Meli ea Kantle – Hangata e entsoe ka tšepe, aluminium, kapa thepa e 'ngoe e fanang ka ho tšoarella le matla a sebopeho.
Moralo oa sandwich o fana ka bokhoni bo botle ba ho jara mojaro ka boima bo fokolang, e leng se etsang hore e be khetho e khahlang bakeng sa lits'ebetso moo ho hlokahalang ho thibela mocheso le botsitso ba sebopeho, joalo ka marulelong, maboteng le mahlakoreng a ka pele.
Mefuta ea Liphanele tsa Sandwich
Liphanele tsa Sandwich tsa Foam tsa Polyurethane – E tsebahala ka thepa ea eona e ntle ea ho thibela mocheso le ho boloka matla hantle.
Liphanele tsa Sandwich tsa Foam tsa Polyisocyanurate (PIR) – E tšoana le diphanele tsa foam tsa polyurethane empa e na le khanyetso e matla ya mollo.
Liphanele tsa Sandwich tsa Boea ba Mineral – E loketse lits'ebetso tse matla tsa ho thibela mollo le ho thibela molumo, hangata e sebelisoa libakeng tsa indasteri.
Karolo ea Polyurethane ho Liphanele tsa Sandwich
Foam ea polyurethane ke e 'ngoe ea thepa ea mantlha e sebelisoang haholo liphanele tsa sandwich ka lebaka la thepa ea eona e phahameng ea ho thibela mocheso, tlhaho e bobebe, le katleho ea litšenyehelo. Foam ea polyurethane e fana ka khanyetso e phahameng ea mocheso, e thusa ho boloka mocheso oa kahare le ho fokotsa tšebeliso ea matla mehahong. E boetse e eketsa matla le ho tiea phanele ntle le ho eketsa boima ba eona haholo.
Melemo ea Bohlokoa ea Polyurethane Core ka har'a Liphanele tsa Sandwich:
Ho Sireletsa Thermal ka Botle – E thusa ho boloka mocheso o tsitsitseng le ho fokotsa litšenyehelo tsa matla.
E bobebe – Ho bonolo ho sebetsana le tsona, ho li tsamaisa le ho li kenya.
Ho tšoarella – E fana ka ts'ebetso e tšoarellang nako e telele ka ho hanyetsa mongobo, lik'hemik'hale le ho tsofala ha 'mele.
E boloka litšenyehelo – E fana ka tekatekano pakeng tsa tshebetso le theko e tlase.
Bohlokoa ba Li-Catalyst tsa Polyurethane Tlhahisong ea Liphanele tsa Sandwich
Tlhahiso ea liphanele tsa sandwich tse thehiloeng ho polyurethane e itšetlehile haholo ka tšebeliso ea li-catalyst tsa polyurethane. Li-catalyst tsena li tsamaisa liketso tsa lik'hemik'hale lipakeng tsa li-polyol le li-isocyanate, e leng likarolo tse peli tsa mantlha tsa foam ea polyurethane. Khetho e nepahetseng ea li-catalyst e netefatsa hore foam e nts'etsapele thepa e lakatsehang, joalo ka ho teteana, ho thibela mocheso le matla a mechini, ha ka nako e ts'oanang e ama katleho ea tlhahiso.
Li-catalyst tsa polyurethane li ka aroloa ka lihlopha tse peli tse kholo:
Li-Catalyst tsa Amine – Khothaletsa karabelo ea ho fofonela, e thusang ho theha sebopeho sa sele sa foam.
Li-Catalyst tsa Tšepe – Potlakisa karabelo ea gelling, e leng se tlatsetsang matla le ho tiea ha foam.
Mesebetsi ea Bohlokoa ea Li-Catalyst tsa Polyurethane:
Lebelo la Karabelo ea Taolo – Li-catalyst li laola lebelo leo foam ea polyurethane e thehoang ka lona, li netefatsa boleng bo tsitsitseng le ho thibela liphoso tse kang ho tetebela kapa ho se khomarele hantle.
Ntlafatsa Matlotlo a Foam – Li-catalyst li susumetsa ho teteana ha foam, matla le ho tsamaisa mocheso, e leng lintlha tsa bohlokoa ts'ebetsong ea phanele ea sandwich.
Ntlafatsa Tlhahiso – Li-catalyst tse sebetsang hantle li fokotsa linako tsa tlhahiso ka ho potlakisa ts'ebetso ea ho etsoa ha foam, e leng se lumellang bahlahisi ho hlahisa liphanele tsa sandwich kapele le ka mokhoa o theko e tlase.
Litharollo tsa Polyurethane Catalyst bakeng sa Liphanele tsa Sandwich
Ho Mingxu Chemical, re hlahisa mefuta e mengata ea li-catalyst tsa polyurethane tse etselitsoeng ka ho khetheha tlhahiso ea liphanele tsa sandwich. Li-catalyst tsa rona li nolofalletsa bahlahisi ho ntlafatsa lits'ebetso tsa ho foamisa le ho folisa, ho netefatsa ts'ebetso e ntle le katleho ea litšenyehelo tsa sehlahisoa sa ho qetela.
MXC-TMA: Sethatsi sa ho Thibela ho Sebetsa ka Bongata
E 'ngoe ea lihlahisoa tsa rona tse hlahelletseng bakeng sa tlhahiso ea liphanele tsa sandwich keMXC-TMA, e leng catalyst ea amine e phahameng e khothalletsang karabelo ea trimerization, e lebisang ho thehoeng ha foam ea polyisocyanurate (PIR). Foam ea PIR e hlomphuoa haholo ka lebaka la ho hanyetsa mollo ha eona ho feta foam e tloaelehileng ea polyurethane, e leng se etsang hore e be khetho e ratoang liindastering moo polokeho ea mollo e leng taba e tšoenyang.
Likarolo tsa Bohlokoa tsaMXC-TMA:
Sekhutlo se sa Tloaelehang le se Laolehang sa ho Phahama – E netefatsa boleng bo tsitsitseng ba foam ho pholletsa le diphanele tsohle.
Mokelikeli o Ntlafalitsoeng – E ntlafatsa mokhoa oa ho sebelisa, e lumella foam ho tlatsa likheo le ho khomarela hantle le likarolo tse ka ntle.
Phekolo e ntlafalitsoeng – E fana ka linako tse potlakileng tsa ho fola, e ntlafatsa tlhahiso ntle le ho lahla boleng.
Ntle le MXC-TMA, re fana ka mefuta e meng ea li-catalyst tse etselitsoeng litlhoko tse ikhethileng tsa bahlahisi ba liphanele tsa sandwich tsa polyurethane, ho kenyeletsoa le li-catalyst tse ntlafatsang ho hanyetsa mollo, ho ntlafatsa botsitso ba foam, le ho fokotsa monko nakong ea tlhahiso.
Qetello
Tlhahiso ea liphanele tsa sandwich tsa boleng bo holimo e itšetlehile ka khetho e hlokolosi ea thepa le likarolo tsa lik'hemik'hale, tseo har'a tsona foam ea polyurethane le li-catalyst tsa polyurethane li bapalang karolo ea bohlokoa. Thepa ea foam e ama ka kotloloho ts'ebetso ea ho thibela mocheso, matla a sebopeho le ho tšoarella ha nako e telele ha liphanele tsa sandwich, ha catalyst e nepahetseng e netefatsa ts'ebetso e sebetsang ea tlhahiso le boleng bo tsitsitseng ba sehlahisoa.
Ho Mingxu Chemical, re ikemiselitse ho fana ka lits'ebeletso tse tsoetseng pele ditharollo tsa di-catalyst tsa polyurethane d ho fihlela ditlhoko tse ntseng di fetoha tsa indasteri ya diphanele tsa sandwich. Ka ho sebedisa boiphihlelo ba rona ba k'hemistri ya polyurethane, re thusa bahlahisi ho ntlafatsa ditshebetso tsa tlhahiso, ho fokotsa ditjeo le ho fa bareki dihlahiswa tsa boleng bo hodimo.
Haeba u moetsi oa liphanele tsa sandwich 'me u batla li-catalyst tsa polyurethane tse tšepahalang, tse sebetsang hantle, ka kopo ikopanye le rona kajeno ho ithuta haholoanyane ka hore na re ka tšehetsa khoebo ea hau joang.
