I-N, N, N ', N'-tetramethyl dipropylene triamine (FENTACAT 15, PC15)

Izici nokusetshenziswa:

I-N, N, N ', N'-tetramethyldipropylenetriamine (FENTACAT 15, PC15) iyinhlangano ye-amine equilibrium catalyst engathumeli, enokukhetha okuncane kokuphendula kwe-urea (isocyanate-water);
I-N, N, N ', N'-tetramethyldipropylenetriamine (FENTACAT 15, PC15) iqukethe i-hydrogen esebenzayo, ngakho-ke kulula ukuphendula ku-matrix ye-polymer, ngakho-ke ngeke kube khona ukukhishwa okungahambi kahle;
I-N, N, N ', N'-tetramethyldipropylenetriamine (i-FENTACAT 15, i-PC15) ithuthukisa ukubekezelela kobuso kwezinhlelo zokubumba ezithambile, futhi ingasetshenziswa ezinhlelweni eziqinile ze-polyurethane ezidinga ukusabela okubushelelezi.

Ukucaciswa:

Iphakheji nokugcina:

I-N, N, N ', N'-tetramethyldipropylenetriamine (I-FENTACAT 15, PC15) igcwele ngo-165 kg / isigubhu; egcinwe endaweni epholile futhi engenisa umoya ngaphakathi ezindlini, evikelwe emswakeni nasekuvezweni yilanga. Isikhathi sokugcina siyizinyanga eziyi-12.

Ukuvikelwa kokuphepha:

N, N, N ', N'-tetramethyldipropylenetriamine9 I-FENTACAT 15, PC15) kuyinto synthesis zamakhemikhali impahla Lesisemkhatsini. Sicela ugweme ukuxhumana namehlo nesikhumba ngesikhathi sokusetshenziswa. Uma kukhona othintana naye, sicela ugeze ngamanzi amaningi bese uwuthumela kudokotela ukuze athole ukwelashwa.
