I-CAS 69102-90-5 HTPB i-propellant eqinile ye-Hydroxyl-terminated polybutadiene HTPB ye-propellant, i-adhesive, sealant
I-HTPB / Hydroxyl-terminated polybutadiene CAS: 69102-90-5
Imininingwane yomkhiqizo:
Igama Lekhemikhali: I-Hydroxyl-terinated polybutadiene
Ikhodi: HTPB, HTPB-R45M
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)
It kanye ne-agent ye-chain extension, i-crosslinking ejenti ekamelweni lokushisa noma ukusabela kokushisa okuphezulu kungakhiqiza isakhiwo senethiwekhi ye-3D yokuqukethwe okuphulukisayo.Okuqukethwe okuphulukisayo kunezici ezinhle kakhulu zemishini, ikakhulukazi ukumelana okuhle ne-hydrolysis, i-asidi ne-alkali ukumelana, ukumelana nokugqoka, ukumelana nokushisa okuphansi kanye ukufakwa kahle kagesi.
Ama-polyurethanes alungiselelwe kusuka ku-HTPB angakhelwa izakhiwo ezithile ezibonakalayo; i-polyurethanes ingase ibe nokunwebeka kakhulu noma ibe nzima futhi iqine. Eminye imikhiqizo ihlanganisa: amaphaneli okufakwa kwegwebu aqinile; amasondo aqinile e-elastomeric namathayi (asetshenziselwa ama-roller coasters, ama-escalators, ama-skateboards, njll.); amabhasikidi okumiswa kwezimoto; ama-potting compounds kagesi; ama-adhesives asebenza kahle kakhulu; izigqoko ezingaphezulu kanye nama-sealants ebusweni; imicu yokwenziwa (isb, Spandex); ukhaphethi ongaphansi; izingxenye zepulasitiki eziqinile (isb, izinsimbi zikagesi).
Ukusetshenziswa okubalulekile kwe-HTPB ku-rocket propellant eqinile. Ibophezela i-oxidizing agent, uphethiloli nezinye izithako zibe yisisindo esiqinile kodwa esinwebekayo kumasistimu amaningi akhiqizayo ayinhlanganisela. I-polyurethane ephulukisiwe isebenza njengophethiloli ezixubeni ezinjalo. Isibonelo i-propellant njenge-"HTPB/AP/Al=12/68/20", okusho ukuthi, ihlukaniswe ngobuningi, i-HTPB kanye nokwelapha okungu-12% (i-binder kanye nophethiloli), i-ammonium perchlorate 68% (oxidizer), kanye ne-aluminium powder 20% (uphethiloli).
Ama-propellant afanayo, avame ukubizwa ngokuthi i-APCP (i-ammonium perchlorate composite propellant) asetshenziswa kumarokhethi amamodeli amakhulu. I-APCP evamile ikhiqiza izikhathi ezingu-2-3 ukushukumisa okuthile kwempushana emnyama esetshenziswa kumamothore amarokhethi amancane kakhulu.
I-HTPB iphinde isetshenziswe njengamafutha e-rocket e-hybrid.
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
- 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.
