Li-elastomer tsa polyurethane ke sehlopha sa li-polymer tse feto-fetohang, tse sebetsang hantle tse sebelisoang liindastering tse kenyeletsang likoloi, kaho, lieta le tlhahiso ea indasteri. Motsoako oa tsona o ikhethang oa ho tiea, ho tenyetseha le ho hanyetsa lik'hemik'hale li etsa hore li be ntle bakeng sa libaka tse hlokang tlhokomelo e ngata. Karolo ea bohlokoa, eo hangata e hlokomolohuoang ho hlahiseng li-elastomer tsa polyurethane tsa boleng bo holimo ke sistimi ea catalyst—haholo-holo li-catalyst tsa amine, tse thusang ho laola boemo ba karabelo le thepa ea ho qetela ea thepa.
Ho MINGXU NEW MATERIALS, re ikhethile ka ho hlahisa di-catalyst tsa polyurethane tse sebetsang hantle. E 'ngoe ea lihlahisoa tsa rona tse hlahelletseng, MXC-37 (DMAEE), e bapala karolo ea bohlokoa lits'ebetsong tse fapaneng tsa elastomer ka ho ntlafatsa kinetics ea karabelo ha ka nako e ts'oanang e netefatsa hore mosi o tsoa tlaase le monko o fokolang.
Li-Catalyst tsa Polyurethaneho Sistimi ea Elastomer
Mefuteng ea elastomer ea polyurethane, li-catalyst li laola sekhahla sa likarabo tse peli tsa mantlha:
1. Karabelo ea gelling (polyol le isocyanate)
2. Karabelo ea ho foka (metsi le isocyanate)
Ho fapana le mafome, hangata li-elastomer li hloka ho foka hanyane ho boloka botsitso ba sebopeho bo tiileng. Leha ho le joalo, lits'ebetsong tse itseng joalo ka li-elastomer tsa microcellular kapa reaction injection molding (RIM), teka-tekano e ntle pakeng tsa ho foamela le ho etsa gelling ke ea bohlokoa bakeng sa ho fihlela boima bo lakatsehang, ho mamella le ho qeta bokaholimo.
MXC-37 (DMAEE): Sesebediswa se Matla sa Amine sa Tshebetso e Phahameng bakeng sa Elastomers
MXC-37, e tsejoang hape e le 2-dimethylaminoethylethanol (DMAEE), ke sesebelisoa sa amine se seholo se etselitsoeng ho fana ka ts'ebetso e ikhethang lits'ebetsong tsa elastomer le microcellular. E sebetsa haholo-holo mefuteng e nang le metsi a mangata, moo taolo ea foam le taolo ea monko li leng bohlokoa.
Melemo ea Bohlokoa ea MXC-37 ho Elastomers:
Monko o Tlase, Moralo o sa Hlahiseng Mosi:Jwalo ka sehlomathiso se sa ntsheng mosi le se nang le monko o tlase, MXC-37 e fokotsa monko o ikgethang wa amine dikarolong tse fedisitsweng tsa elastomer—haholoholo tsa bohlokwa kahare ho dikoloi le thepa ya bareki.
Mosebetsi o Fofomelang ka ho Fetisisa:Esita le ditsamaisong tsa elastomer tse nang le foam e tlase kapa e laolwang, MXC-37 e tshehetsa sebopeho sa sele se tshwanang le taolo e nyane ya bongata ha ho hlokahala ditlamorao tsa disele tse nyane.
Ho lumellana ho hotle haholo:MXC-37 e tsamaisana le mefuta e mengata ea litsamaiso tse thehiloeng ho polyester le polyether, e leng se etsang hore e lokele li-elastomer tse bonolo le tse tiileng, hammoho le foam e bonolo e thehiloeng ho ester le sephutheloana sa foam e tiileng.
Tšebeliso e Tenyetsehang: E sebelisoa hangata ho:
Li-elastomer tsa polyurethane tse nyenyane (mohlala, lithapo tsa lieta, libaka tsa ho phomola matsoho)
Sistimi ea RIM (li-bumper tsa likoloi, liphanele)
Lifoam tsa elastomer tse tenyetsehang tse mamellang habonolo
Liphutheloana tsa sebopeho le li-elastomer tsa ho kenya mocheso
Hobaneng o lokela ho kgetha MXC-37 bakeng sa Sistimi ya Hao ya Elastomer?
Tlhahiso ea li-elastomer tsa polyurethane tse sebetsang hantle e hloka ho nepahala, ho tsitsa le taolo. MXC-37 e fana ka tsena tsohle ha e ntse e thusa baetsi ba liforomo ho fihlela maemo a thata a tikoloho le a bophelo bo botle mosebetsing. Hore na u ntse u nts'etsapele likarolo tse bobebe tsa likoloi kapa likarolo tsa indasteri tse tšoarellang, MXC-37 e ntlafatsa ts'ebetso le boleng ba sehlahisoa.
Qetello
Ha tlhoko ea litsamaiso tsa elastomer tsa polyurethane tse hloekileng le tse sebetsang hantle e ntse e tsoela pele ho hola, ho khetha catalyst e nepahetseng ho bohlokoa ho feta leha e le neng pele. MXC-37 (DMAEE) e fana ka ts'ebetso, ho latela tikoloho, le ho tenyetseha ho hlokahalang ho fihlela litlhoko tsa tlhahiso ea sejoale-joale.
Ikopanye le rona kajeno ho ithuta kamoo MXC-37 e ka ntlafatsang sebopeho sa hau sa polyurethane elastomer.
