Iqembu elilodwa le-hydroxyl HTPB CAS 69102-90-5 I-Hydroxyl-terminated polybutadiene HTPB eneketanga elilodwa le-hydroxyl -OH kanye nenguqulo ye-hydrogenated
I-HTPB / i-Hydroxyl-terminated polybutadiene CAS: 69102-90-5
Imininingwane yomkhiqizo:
Igama Lekhemikhali: Iqembu elilodwa le-hydroxyl HTPB / i-Hydroxyl-terminated polybutadiene
Ikhodi: HTTPB-OH
I-CAS: 69102-90-5
Ifomula:
Uhlamvu: Ilayisensi yokuthumela ngaphandle egunyaziwe yaseShayina / yokuthumela ngaphandle ye-HTPB
Okujwayelekile: GB (Ibanga Lomphakathi) / GJB (Ibanga Lezempi/ GJB 1327A-2003)
I-HTPB iyi-polymer ye-claw eqhelile ewuketshezi, irabha entsha ewuketshezi. Izakhiwo ziyahlukahluka ngoba i-HTPB iyinhlanganisela kunokuba ibe yikhompawundi emsulwa, futhi yenziwe ukuze ihlangabezane nezidingo ezithile zamakhasimende. I-HTPB ejwayelekile yi-R-45M lapho ukuphela ngakunye kweketanga kuqedwa khona ngeqembu le-hydroxyl [OH].PS: singenza noma yiziphi izinguqulo ze-HTPB njengoba amakhasimende ecela, futhi siklame i-HTPB entsha ngochungechunge olulodwa lwe-hydroxyl -OH, Okwamanje, singenza i-hydrogenation ye-HTPB)
Iqembu elilodwa le-hydroxyl i-HTPB liwumkhiqizo we-polybutadiene onamaqembu e-hydroxyl ngakolunye uhlangothi, ongafinyelela ukuphiliswa okuphindwe kabili kwamaqembu e-hydroxyl kanye ne-vinyl. Ine-reactivity ephezulu, i-hydrophobicity enhle kakhulu kanye nezakhiwo ze-dielectric, kanye nokusebenza okuhle kokucubungula.
I-HTPB inobukhulu obuhle, i-viscosity ephansi, ukumelana nokuguga, ukusebenza kahle kwezinga lokushisa eliphansi, ukumelana ne-hydrolysis, ukumelana ne-asidi ne-alkali, ukumelana nokuguguleka kanye nezakhiwo ezinhle kakhulu zokuvimbela ugesi
futhi ukusebenza kahle kokucubungula kuhle. I-HTTPB ingasetshenziswa ku:
- Inamathelayo
- Izinto zokuvala
- Ama-polymer
- Izinto zokuvikela ugesi
- Izinto zokuvikela ukuvimbela amanzi kanye nokugqwala
- Ukugqoka
- Izinto ze-polyurethane
- Imikhiqizo yerabha
- Uphethiloli oqinile
- I-Propellant
- Amathayi ezimoto nezindiza ngezinto zokwakha
- I-propellant ye-polybutadiene eqediwe yi-hydroxyl (HTPB+AP+Al)
- Izindiza, Amarokhethi kanye Neziqhumane
- amafutha okugcoba
- kanye nezinhlobo eziningi zokusetshenziswa.
Ukupakisha:
Ipakishwe ku-50kg/isigubhu, 170kg/isigubhu, Isikhathi sokugcina singunyaka owodwa.
Imiyalelo yokuphepha:
Indawo yokugcina kufanele ibe sendaweni epholile, eyomile futhi engenisa umoya. Isimo esihle kakhulu siphakathi kuka -20 ~ 38℃. Isikhathi sokuphila seshelufu sezinyanga ezingu-12, uma siphelelwa yisikhathi, singasetshenziswa uma sisezingeni elijwayelekile ngokuhlolwa kabusha. Lapho ukuthutha kufanele kugweme imvula, ukukhanya kwelanga. Ungaxubani ne-oxidizer enamandla.
