Ama-foam aguquguqukayo e-polyurethane asetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yobumnene bawo, ukuqina, kanye nokuguquguquka kwawo. Indima yama-catalyst e-polyurethane enqubweni yokukhiqiza ibalulekile ekufezeni izakhiwo ezifiselekayo njengokufana kwe-pore, ukuqina, kanye nokunamathela okuthuthukisiwe. Ama-catalyst amabili athile, i-MXC-BDMA kanye ne-MXC-70, abonisa ukubaluleka kwama-catalyst akhethwe ngokucophelela ekwakhiweni kwe-foam eguquguqukayo.
1. I-MXC-BDMA (CAS 103-83-3)– I-Benzyl Dimethylamine Catalyst
I-MXC-BDMA iyisithako esisetshenziswa kabanzi kwi-polyester polyurethane bulk soft foam, i-polyurethane rigid foam, kanye ne-sheet and adhesive coatings. Nakuba isetshenziswa kakhulu kuma-rigid foam, inezinzuzo eziphawulekayo ekukhiqizweni kwe-flexible foam:
- Ukugeleza Kwasekuqaleni:I-MXC-BDMA iqinisekisa ukugeleza okuhle kwasekuqaleni, okuvumela ingxube ye-polyurethane ukuthi igeleze kahle iye ezikhumbeni nasezimbotsheni, okubalulekile ekusetshenzisweni kwe-foam eguquguqukayo.
- Imigodi Efanayo:I-catalyst inegalelo ekwakhekeni kwamaseli e-foam afanayo, ahlelwe kahle. Ukufana kwesakhiwo samaseli kubalulekile ekufezeni izakhiwo ze-foam ezihambisanayo njengokunciphisa kanye nokuqina.
- Ukuthuthukiswa Kokunamathela:Ngezinhlelo zokusebenza ezidinga ukuthi igwebu linamathele ku-substrate, i-MXC-BDMA ithuthukisa ukunamathela, iqinisekisa umkhiqizo ozinzile nohlala isikhathi eside.
2. I-MXC-70 (CAS 1739-84-0)- I-Catalyst Esekelwe ku-Amine
I-MXC-70 ingenye i-catalyst eguquguqukayo, esetshenziswa kakhulu ekwakhiweni kwe-foam eqinile kodwa enezinzuzo ezibalulekile ekukhiqizweni kwe-foam eguquguqukayo, ikakhulukazi kuma-foam aguquguqukayo aphezulu (HR) namabhulokhi asekelwe ku-ester:
- Ukuthuthukisa Ukuqina Nokuqina Kwesikhumba:Lesi sikhuthazi esisekelwe kuma-amine sithuthukisa inqubo yokwelapha, sinciphisa ukuqhekeka komkhiqizo wokugcina, okwenza igwebu liguquguquke kalula futhi lingaqhekeki kalula.
- Ukuthuthukiswa Kwamandla Aluhlaza:I-MXC-70 iphinde ithuthukise amandla aluhlaza e-foam, inikeze ukuphathwa okungcono phakathi nezigaba zokuqala zokukhiqiza. Lesi sici siwusizo ikakhulukazi kuma-foam aguquguqukayo asetshenziswa ezimotweni nasezintweni zefenisha, lapho ukuqina kubalulekile khona.
- Ukuvumelana nezimo kwesicelo:I-catalyst isebenza kahle nge-polyester ekhabhoni kanye ne-ester-based formulations, inikeza ukuguquguquka ekukhiqizweni kwama-foam aguquguqukayo asebenza kahle kakhulu.
Lesi sihloko singachaza ukuthi zombili lezi zi-catalyst zithuthukisa kanjani ukusebenza kwe-foam, zigqamisa umthelela wazo esakhiweni samaseli esifanayo kanye nokuqina okuthuthukisiwe, okubaluleke kakhulu ekusetshenzisweni kokugcina njengefenisha, izingubo zokulala, izihlalo zezimoto, kanye nokushisa.
