Iqembu elilodwa le-hydroxyl HTPB CAS 69102-90-5 IHydroxyl-terinated polybutadiene HTPB eneketango elilodwa le-hydroxyl -OH kanye nenguqulo ye-hydrogenated
I-HTPB / Hydroxyl-terminated polybutadiene CAS: 69102-90-5
Imininingwane yomkhiqizo:
Igama Lekhemikhali: Iqembu elilodwa le-hydroxyl HTPB / Hydroxyl-terinated polybutadiene
Ikhodi: HTPB-OH
I-CAS: 69102-90-5
Ifomula:
Umlingiswa: Ilayisensi yokuthekelisa yase-China Egunyaziwe / i-HTPB yokuthekelisa
Okujwayelekile: I-GB (Ibanga Lomphakathi) / GJB (Ibanga Lezempi/ GJB 1327A-2003)
I-HTPB iyi-polymer ye-claw ewuketshezi, irabha ewuketshezi entsha. Izakhiwo ziyahlukahluka ngenxa yokuthi i-HTPB iyingxube kunenhlanganisela emsulwa, futhi ikhiqizwa ukuze ihlangabezane nezidingo eziqondile zamakhasimende. I-HTPB ejwayelekile ingu-R-45M isiphetho ngasinye seketango sinqanyulwe ngeqembu le-hydroxyl [OH]. (PS: singenza noma yiziphi izinguqulo ze-HTPB njengoba amakhasimende ecela, futhi siklame okusha i-HTPB ngochungechunge olulodwa lwe-hydroxyl -OH, Okwamanje, singenza i-hydrogenation ye-HTPB)
Iqembu elilodwa le-hydroxyl i-HTPB iwumkhiqizo we-polybutadiene onamaqembu e-hydroxyl ekugcineni, ongafinyelela ukuphulukiswa kabili kwamaqembu e-hydroxyl ne-vinyl. Inokusebenza kabusha okuphezulu, okuhle kakhulu kwe-hydrophobicity kanye nezakhiwo ze-dielectric, nokusebenza okuhle kokucubungula.
I-HTPB ine-diaphaneity enhle, i-viscosity ephansi, ukumelana nokuguga, ukusebenza okuphansi kwezinga lokushisa, ukumelana ne-Hydrolysis, ukumelana ne-asidi ne-alkali, ukumelana nokugqoka kanye nezakhiwo ezinhle kakhulu zokuvala ugesi.
nokusebenza kokucubungula kuhle. I-HTPB ingasetshenziswa ku:
- Ingcina
- Ama-sealents
- Ama-polymers
- Izinto zokufakelwa kukagesi
- Izinto zokuvikela amanzi kanye nokugqwala
- Ukugqoka
- Polyurethane izinto
- Imikhiqizo yenjoloba
- Uphethiloli oqinile
- I-Propellant
- Amathayi ezimoto namaPlanethi ezinto zokwakha
- I-Hydroxyl-terinated polybutadiene propellant(HTPB+AP+Al)
- I-Aerospace, Amarokhethi kanye nemicibisholo
- amafutha okugcoba
- nokunye okuningi kwezinhlobo zokusebenzisa.
Ukupakisha:
Ipakishwe ku-50kg/drum, 170kg/drum, Isikhathi sokugcina unyaka owodwa.
Imiyalo yokuphepha:
Isitoreji kufanele sibe endaweni epholile, yomile futhi ikhiphe umoya. Isimo esihle kakhulu siphakathi -20 ~ 38 ℃. Isikhathi seshelufu sezinyanga eziyi-12, uma siphelelwa yisikhathi, sisasetshenziswa uma sisezingeni ngokuphinda sihlolwe. Lapho ezokuthutha kufanele ugweme imvula, ukukhanya kwelanga. Ungahlanganisi ne-oxidizer eqinile.
