Iyini i-CTPB Carboxyl-Terminated Polybutadiene?
Isakhiwo Samakhemikhali Nezici Eziyinhloko
Uhlangana nawe I-CTPB njenge-polybutadiene ewuketshezi Irabha enamaqembu e-carboxyl kuzo zombili izinhlangothi ze-molecule yayo. Lesi sakhiwo sikunikeza izinto ezisabela kalula nezinye izinto ezihlanganisiwe. Amaqembu e-carboxyl akha izibopho eziqinile futhi athuthukisa ukuqina kwezinamathiseli. Uyaqaphela ukuthi i-CTPB ivelele ngoba ihlanganisa ukuguquguquka nokuqina. I-CTPB kaTheorem Chem inikeza ukumelana nokubanda okuhle kakhulu, ngakho ungayisebenzisa ezindaweni lapho amazinga okushisa ehla khona.
Bheka ithebula elingezansi. Libonisa ukuthi izici ze-CTPB zikusiza kanjani ukufeza ukusebenza okungcono kokunamathela:
| Isici | Umnikelo ekusebenzeni okunamathelayo |
|---|---|
| Isakhiwo Samakhemikhali | Ukuhambisana okuhle kakhulu nama-compounds ahlukahlukene |
| Amaqembu e-Carboxyl | Nikeza amasayithi asabelayo ukuze kube nokuxhumana okuphumelelayo |
| Ukuthuthukiswa Kwamandla Okunamathela | Ingathuthukisa amandla okunamathela ngo-30% |
Uyazuza kulezi zici uma udinga izinto zokunamathisela ezihlala isikhathi eside futhi ezisebenza ngokwethembeka.
Ukuqhathaniswa namanye ama-Polybutadiene
Ungase uzibuze ukuthi i-CTPB iqhathaniswa kanjani namanye ama-polybutadiene. I-CTPB inikeza i-viscosity ephansi kune-CTBN, okwenza kube lula ngawe ukuphatha nokucubungula.
