Liphanele tsa sandwich li fetohile lejoe la motheo la kaho ea sejoale-joale, li fana ka ho thibela mocheso ka mokhoa o ikhethang, matla a sebopeho le ts'ebeliso e ntle ea matla. Motheong oa liphanele tsena ho na le foam ea polyurethane, thepa e etsang hore ts'ebetso ea eona e sebetse ka lebaka la catalyst e nepahetseng. Ho Mingxu Chemical, re ikhethile ka li-catalyst tsa polyurethane tse tsoetseng pele ho ntlafatsa tlhahiso ea liphanele tsa sandwich, ho netefatsa boleng le ts'ebetso e phahameng.
Sehloohong sena, re hlahloba karolo ea bohlokoa ea li-catalyst tsa polyurethane tlhahisong ea liphanele tsa sandwich le kamoo litharollo tsa rona li ka u thusang ho fihlela liphetho tse ikhethang.
Phanele ea sandwich ke eng?
Liphanele tsa sandwich ke thepa e kopaneng e nang le mekhahlelo e meraro:
1. Mealo e 'meli e ka ntle (li-facer): Hangata e entsoe ka tšepe, polasetiki kapa lehong, e fanang ka matla le tšireletso ea sebopeho.
2. Lera la mantlha: Hangata le entsoe ka foam ea polyurethane, e nang le tšireletso e ntle ea mocheso le thepa e bobebe.
Liphanele tsena li sebelisoa haholo kahong, polokelong e batang, kahong ea indasteri le lipalangoangng ka lebaka la ho tšoarella ha tsona, ho boloka matla hantle le ho li kenya habonolo.
Karolo ea li-catalyst tsa polyurethane tlhahisong ea liphanele tsa sandwich
Foam ea polyurethane ke motsoako oa bohlokoa liphanele tsa sandwich, 'me ts'ebetso ea eona e itšetlehile haholo ka catalyst e sebelisoang ts'ebetsong ea tlhahiso. Li-catalyst li bapala karolo ea bohlokoa ho:
1. Ho laola sekhahla sa karabelo: Li-catalyst li laola karabelo lipakeng tsa li-polyol le li-isocyanate, li netefatsa katoloso e ntle ea foam le ho fola.
2. Ho matlafatsa sebopeho sa foam: Li thusa ho theha sebopeho sa sele se ts'oanang, e leng se ntlafatsang ho thibela mocheso le thepa ea mechini ea foam.
3. Ho ntlafatsa ho khomarela: Li-catalyst li netefatsa tlamo e matla pakeng tsa motheo oa foam le lera le ka ntle, e leng se ntlafatsang ho tšoarella ha phanele.
4. Ho ntlafatsa nako ea ts'ebetso: Ka ho potlakisa kapa ho liehisa liketso tse itseng, li-catalyst li lumella bahlahisi ho ntlafatsa katleho ea tlhahiso.
Hobaneng o lokela ho kgetha dikhatalyst tsa diphanele tsa sandwich tsa Mingxu Chemical?
Re fana ka mefuta e fapaneng ea li-catalyst tsa polyurethane tse sebetsang hantle tse etselitsoeng ka ho khetheha tlhahiso ea liphanele tsa sandwich. Li-catalyst tsa rona li fana ka:
✅ Tshebetso e ntle haholo ea ho thibela mocheso: Bokhoni bo botle ba matla ka sebopeho se tšoanang sa sele ea foam.
✅ Matla a eketsehileng a mechini: E ntlafatsa ho tšoarella le bokgoni ba ho jara mojaro ba phanele.
✅ Potoloho e potlakileng ea tlhahiso: Ntlafatsa linako tsa karabelo ho eketsa tlhahiso.
✅ Litharollo tse sireletsang tikoloho: Li-catalyst tsa rona ha li na litšepe tse boima tse kotsi 'me li fihlela litekanyetso tsa botsitso tsa lefats'e.
Li-catalyst tsa rona bakeng sa liphanele tsa sandwich
Li-catalyst tsa rona li etselitsoe ho fihlela litlhoko tse ikhethang tsa tlhahiso ea liphanele tsa sandwich:
1. Liphanele tsa meaho
Bakeng sa diphanele tsa mabota le marulelo tse sebediswang mehahong ya bodulo le ya kgwebo, di-catalyst tsa rona di netefatsa ho kwahela mocheso hantle, ho hanela mollo le botsitso ba sebopeho.
2. Liphanele tse sehatsetsing
Liholong tsa polokelo tse nang le sehatsetsi le likamoreng tse batang, li-catalyst tsa rona li thusa ho hlahisa li-core tsa foam tse nang le motlakase o tlase, ho netefatsa ts'ebetso e ntle ea matla le taolo ea mocheso.
3. Liphanele tsa indasteri
Bakeng sa mehaho ea lifeme le matlo a polokelo, li-catalyst tsa rona li fana ka liphanele tse matla, tse bobebe tse ka mamellang maemo a thata a tikoloho.
4. Liphanele tsa lipalangoang
Liphanele tsa 'mele oa koloi le tsa lijana, li-catalyst tsa rona li netefatsa litharollo tse bobebe, tse tšoarellang le tse sebetsang hantle mochesong.
Lebenkele la rona la liphanele tsa sandwich
Re fana ka mefuta e fapaneng ea li-catalyst tse etselitsoeng ho fihlela litlhoko tse fapaneng tsa tlhahiso:
- Lebitso la sehlahisoa saMXC-37ke 2-(2-(dimethylamino)ethoxy)ethanol, e khutsufalitsoeng e le DMAEE, ka nomoro ea CAS ea 1704-62-7. Ke sesebelisoa sa amine se sa ntšeng letho, se nang le monko o tlase se sebelisoang tlhahisong ea lifoam tsa polyurethane. Ka lebaka la ts'ebetso ea sona e phahameng ea ho fofonela, se loketse haholo bakeng sa liforomo tse nang le metsi a mangata, haholo-holo bakeng sa foam ea polyurethane (SPF) e nang le metsi a fokolang, e nang le metsi a fokolang. Ho kenyelletsa DMAEE ka har'a polymer ho fokotsa monko oa amine o tloaelehileng ho lifoam. E ka sebelisoa e le 'ngoe e le sesebelisoa sa mantlha sa ho fofonela kapa e le sesebelisoa se kopaneng sa ho fokotsa ts'ebeliso ea li-catalyst tsa foam tsa BDMAEE. E sebelisoa ho lifoam tse bonolo tse thehiloeng ho ester, lifoam tsa microcellular, li-elastomers, RIM le RRIM, le lits'ebetsong tsa ho paka foam tse thata.
- MXC-C15e emetse 3,3′-Iminobis(N,n-dimethylpropylamine), CAS NO. 6711-48-4, ke sesebelisoa sa amine se arabelang se sa ntšeng letho, se nang le monko o tlase se khethang hanyane bakeng sa liketso tsa urea (isocyanate-water). E ntlafatsa pheko ea bokaholimo lits'ebetsong tse tenyetsehang tsa ho bopa. E ka sebelisoa lits'ebetsong tse thata tsa polyurethane tse hlokang mothapo o boreleli oa karabelo.
Sebelisana le Mingxu Chemical bakeng sa litharollo tse ntle tsa panel ea sandwich
Re ikemiselitse ho u thusa ho fihlela bokhabane tlhahisong ea liphanele tsa sandwich. Ka li-catalyst tsa rona tse ncha le boiphihlelo ba tekheniki, u ka ntlafatsa lits'ebetso tsa hau tsa tlhahiso le ho fana ka liphanele tsa boleng bo holimo tse fihlelang litlhoko tsa kaho ea sejoale-joale.
