Izinto Ezibalulekile Okufanele Uzicabangele
- I-HTTPBAma-polyurethane elastomer asekelwe kuwo ahlala eguquguqukayo futhi eqinile ngisho nasemazingeni okushisa aphansi kakhulu, okwenza abe afaneleke kakhulu ezindaweni ezibandayo.
- Lawa ma-elastomer anikeza ukumelana okuhle kakhulu kwe-UV kanye nokumuncwa kwamanzi okuncane, okuqinisekisa ukuqina ezimweni zangaphandle nezinzima.
- I-HTTPBIzakhiwo ezihlukile zika-'s zivumela izinhlelo zokusebenza eziguquguqukayo kuzo zonke izimboni ezifana nezindiza, izimoto, kanye ne-elekthronikhi, okuqhuba ukukhula okukhulu kwemakethe.
Ukusetshenziswa kwe I-HTPB (i-Hydroxyl-terminated polybutadiene CAS 69102-90-5) Kuma-Polyurethane Elastomers: Yini Eyenza Ihluke
Incazelo kanye nesakhiwo se- I-HTTPB
Ungase uzibuze ukuthi yini eyenza i-HTPB ibe ekhethekile. I-HTPB imele i-hydroxyl-terminated polybutadiene. Le nto inesakhiwo esiyingqayizivele esiyinika izakhiwo eziningi eziwusizo. Uthola amaqembu e-hydroxyl kuzo zombili izinhlangothi ze-molecule ye-HTPB. La maqembu asabela kakhulu ngama-isocyanates, okusiza ekwakheni izibopho eziqinile ze-urethane. Umgogodla we-HTPB wenziwe ngamayunithi e-butadiene aguquguqukayo. Lesi sakhiwo sikunikeza into ehlala ithambile futhi inwebeka, ngisho nasesimo sezulu esibandayo.
- I-HTPB inokushisa okuphansi kokushintsha kwengilazi, ngokuvamile okuphakathi kuka -75°C kuya ku -80°C.
- I-molecule inganwebeka kakhulu ngaphambi kokuphuka, kanti kwezinye izimo iyanda lapho iphuka ngaphezu kuka-1000%.
- I-HTPB imelana namanzi futhi ayimunci umswakama omningi, ngakho-ke isebenza kahle ezindaweni ezimanzi noma ezinzima.
Izici Eziyinhloko ku-Polyurethane Elastomers
Uma usebenzisa I-HTTPB kuma-polyurethane elastomers, uthola izinzuzo eziningana ezibalulekile. Ukusetshenziswa kwe-HTPB kuma-polyurethane elastomers kukunikeza imikhiqizo ehlala iguquguquka futhi iqinile ezimweni eziningi. Amaqembu e-hydroxyl ekugcineni kwe-HTPB asabela ngokushesha ngama-isocyanates. Lokhu kusabela kwakha inethiwekhi eqinile, ekhulisa ukuqina kanye namandla okudonsa.
- I-Cured HTPB imunca amanzi angaphansi kuka-1% ngesisindo. Lokhu kusiza ukuvikela izingxenye ezibucayi emswakama.
- Uthola ukumelana okuhle kwe-UV, ngakho imikhiqizo yakho ihlala isikhathi eside ngaphandle.
- I-HTPB ingashintshwa ngamakhemikhali akhethekile, njengeqembu elisekelwe ku-triazine. Lezi zinguquko zingathuthukisa amandla futhi zengeze nezici ezintsha, njenge-photoluminescence.
| Ukuqamba Okubalulekile | Incazelo |
|---|---|
| Izingxenye ezisekelwe ku-Triazine | La maqembu aseziphethweni ze-HTPB athuthukisa amandla nokuzinza ngokusebenzisa amandla aqinile kagesi. |
