I-Polyurethane ibilokhu iqashelwa njengento eguquguqukayo kakhulu, futhi ukuguquguquka kwayo kuyenza ibe ukukhetha okuhle kwezicelo ezahlukahlukene zezimboni, ikakhulukazi kuma-Coatings, Adhesives, Sealants, kanye nama-Elastomers (CASE). Lezi zicelo zidinga ama-catalyst asebenza kahle kakhulu angathuthukisa i-reaction kinetics ngenkathi eqinisekisa ukusebenza komkhiqizo okuphezulu. Kubakhiqizi bezinhlelo ze-polyurethane, ukukhetha i-catalyst efanele kuyisihluthulelo sokulinganisela ukusebenza kahle, ukuphepha, kanye nokuphila isikhathi eside komkhiqizo.
Uhla lwethu lwe-polyurethane catalysts ezisebenza kahle lunikeza izixazululo ezenzelwe izidingo ezithile zezicelo ze-CASE, kusiza abakhiqizi ukuthi bafinyelele izakhiwo ezinhle kakhulu njengokunamathela, ukuguquguquka, kanye nokumelana nezici zemvelo. Phakathi kwe-catalysts zethu ezihamba phambili,I-MXC-R70I-(2-(2-dimethylaminoethoxy)ethanol, i-CAS 1704-62-7) ivelele ngokusabela kwayo kanye nokufaneleka kwayo kuzo zonke izinhlobo ze-foam kanye nemikhiqizo ye-elastomeric.
Indima Ka-Ama-Catalystkuzicelo ze-CASE
Ama-catalyst asebenza njengomgogodla wezindlela zamakhemikhali eziguqula ukwakheka kwe-polyurethane okuwuketshezi kube imikhiqizo eqinile, esebenza kahle kakhulu. Asheshisa kokubili ukusabela kwe-foam (ukuvuthela) kanye nokwelapha (ukugaya), okuqinisekisa ukuthi umkhiqizo wokugcina unezakhiwo ezifunwayo zemishini nezomzimba.
Ezinhlelweni ze-CASE, lokhu kusho ukuthuthukisa izici ezibalulekile ezifana nalezi:
- Ukunamathela: Ukuqinisekisa ukubopha okuqinile phakathi kwezindawo, okubalulekile ezintweni zokunamathisela kanye nezinto zokuvala.
- Ukuzivumelanisa nezimo kanye nokuqina: Ukufinyelela ukuqina okuhlala isikhathi eside kanye nokumelana nokuguguleka kuma-elastomer.
- Ukuqedwa Komphezulu: Ukuthuthukisa ukufana kanye nezakhiwo zobuhle bezingubo zokumboza.
- Ukusebenza Kahle Kokucubungula: Ukwenza kube lula ukukhiqiza ngokushesha ngezikhathi zokwelashwa ezilungiselelwe kahle.
Izicelo Eziyinhloko zeI-MXC-R70uma kwenzeka
I-MXC-R70, i-volatible amine catalyst, idlala indima ebalulekile ekukhiqizeni imikhiqizo ehlukahlukene esekelwe ku-polyurethane, kufaka phakathi ama-microcellular foams nama-elastomers. Ukusebenza kwayo okuphezulu kwenza ifaneleke kakhulu ezinhlotsheni ze-vinyl foam ezifana nama-dashboard ezimoto kanye nama-headrest, lapho kudingeka khona ukunemba nokuqina. Ngokukhuthaza ukuqiniswa okusheshayo ngaphandle kokuphazamisa ukuguquguquka kanye nenduduzo ye-foam, i-MXC-R70 ibalulekile ezinhlelweni zokusebenza ezidinga kokubili ukusebenza okuphezulu kanye nenduduzo.
Izici Eziyinhloko ze-MXC-R70:
- Ukusabela okuphezulu: Ivumela izikhathi zokusabela eziphumelelayo nezisheshayo kokubili ezinqubweni zokukhipha amagwebu kanye nokupholisa.
- Izinhlelo zokusebenza ezisebenziseka kalula: Ifanele ukusetshenziswa okubanzi, kusukela kuma-microcellular foam kuya kuma-elastomers, inikeza izakhiwo zomzimba ezinhle kakhulu ekusetshenzisweni ngakunye.
- Ubuthi obuphansi: Kunciphisa ukuthembela kuma-catalyst ensimbi anobuthi njenge-dibutyltin, okuqinisekisa izinqubo zokukhiqiza eziphephile kubasebenzi nakubakhiqizi.
Ukunciphisa Ukuchayeka Kuma-Catalysts Anobuthi
Ukukhathazeka okukhulayo embonini ye-polyurethane ukunciphisa ukuchayeka kuma-catalyst ensimbi anobuthi njenge-dibutyltin. Uhla lwethu olusha lwama-catalyst, kufaka phakathi i-MXC-R70, lunikeza enye indlela ephephile ngokunciphisa noma ukuqeda isidingo salezi zinto eziyingozi. Lokhu akugcini nje ngokuthuthukisa ukuphepha endaweni yokusebenza kodwa futhi kuhambisana nemithethonqubo yezemvelo eshintshashintshayo kanye nezidingo zabathengi zemikhiqizo ehlanzekile neluhlaza.
