Njengomhlinzeki ohamba phambili wama-catalyst e-polyurethane, siyajabula ukugqamisa indima ebalulekile edlalwa yilawa ma-catalyst ekukhiqizweni kwe-polyurethane foam, into eguquguqukayo esetshenziswa ezimbonini ezahlukahlukene. Imikhiqizo yethu, kufaka phakathi i-MXC-A33, i-MXC-T kanye nezinye izinhlobo ezahlukene zama-catalyst akhethekile, iyingxenye ebalulekile yenqubo yokukhiqiza i-polyurethane foam, iqinisekisa ukusabela okuphumelelayo kanye nemiphumela yokusebenza okuphezulu.
Indlela Eyenziwa Ngayo I-Polyurethane Foam
I-polyurethane foam ikhiqizwa ngokusebenzisa ukusabela kwamakhemikhali phakathi kwama-diisocyanates nama-polyol, womabili atholakala ku-oyili ongahluziwe, yize ama-polyol angakhiwa futhi ku-oyili yemvelo evuselelekayo. Lokhu kusabela kuphumela kuchungechunge lwe-polymer olwakha isakhiwo esiyinhloko se-foam. Ukukhiqizwa kwe-polyurethane foam kuhilela izingxenye eziyisithupha eziyinhloko:
- Ama-Polyols: Isakhiwo esiyinhloko se-foam, sisabela ngama-diisocyanates.
- Ama-Diisocyanate: Ama-reactant ayisihluthulelo ahlangana nama-polyol ukudala i-foam.
- Izinto zokukhiqiza amagwebuLokhu kusiza ekwakheni isakhiwo seseli se-foam.
- Ama-surfactant: Qinisa igwebu ngesikhathi senqubo yalo yokukhulisa.
- Ama-Catalyst: Sheshisa ukusabela phakathi kwama-polyol nama-diisocyanates, uqinisekise ukwakheka kwe-foam okuhle kakhulu.
- Ama-Hardeners: Ama-crosslinkers kanye nama-chain extenders asetshenziselwa ukuthuthukisa ukuqina nokusebenza kwe-foam.
Uma lezi zithako zihlanganiswa, ziyasabela ngamakhemikhali, zikhiqize ukushisa, igesi, kanye nesakhiwo esiyingqayizivele se-foam. Ama-catalyst afana ne-MXC-A33 yethu kanye ne-MXC-T enza kube lula lokhu kusabela, aqinisekise inqubo elawulwayo nephumelelayo.
Izicelo ze-Catalyst ku-Polyurethane Foam
I-polyurethane foam iza ngezinhlobo ezimbili eziyinhloko: eqinile futhi eguquguqukayo. Ukusetshenziswa kwayo kuhluka kusukela ekufakweni kokushisa ekwakhiweni (i-rigid foam) kuya ekufakweni kwefenisha kanye nengaphakathi lezimoto (i-flexible foam). Ama-catalyst ethu enzelwe ukuhambisana nezidingo ezahlukene:
-I-MXC-A33:I-catalyst eyakhiwe yi-33% TEDA (triphenylenediamine) kanye ne-67% DPG (i-monoconjugated dipropylene glycol), eyenzelwe ngqo ama-polyurethane foam kanye ne-polyurethane elastomers. Isetshenziswa kabanzi kwi-polyurethane foam ethambile, eqinile, neqinile, kanye ne-elastomer.
-I-MXC-T:Kuyi-catalyst ye-amine esebenza kahle, engenawo ugesi enikeza ijika lokusabela elibushelelezi futhi ngenxa yalokho ingasetshenziswa ukukhiqiza izinhlobo ezahlukene zama-polyurethane foam. Isenzo sayo sokuvuselela sikhuthaza ukusabela kwe-urea (i-isocyanate yamanzi), evame ukusabela ne-polymer matrix ngenxa yeqembu layo elisebenzayo le-hydroxyl. Ngenxa yalesi sizathu, i-TMAEA isetshenziselwa ukufafaza ukufakelwa kwe-foam, amadeshibhodi ezimoto, nezinye izindawo ezidinga iphunga eliphansi elisele..
Ama-catalyst e-polyurethane aqinisekisa amazinga okusabela afanele, izakhiwo ze-foam ezilungiswa kahle njengobuningi, ubulukhuni, kanye nobuqotho besakhiwo. Lokhu kunemba kwenza i-polyurethane foam ikwazi ukuhlangabezana nezidingo eziqinile zezimboni zanamuhla, okuhlanganisa ezokwakha, ezimoto, ifenisha, kanye nokupakishwa.
Mayelana NATHI
Singumhlinzeki ohamba phambili wama-catalyst e-polyurethane asebenza kahle kakhulu, sizibophezele ekuletheni izixazululo ezintsha zezicelo ezahlukahlukene zezimboni. Uhlu lwethu olubanzi lomkhiqizo lusiza abakhiqizi ukuthi bathuthukise izinqubo zokukhiqiza i-foam ngenkathi behlangabezana nezindinganiso zemvelo nezokulawula.
