I-Hydrogenated Hydroxyl Group-Terminated Polybutadiene
I-hydrogenated I-HTTPB I-Hydrogenated Hydroxyl Group-Expinated Polybutadiene
Imininingwane yomkhiqizo:
Igama Lekhemikhali: I-Hydrogenated HTPB
Uhlobo: Inguqulo ye-hydrogenated
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)
Ku-hydrogenated HTPB kukhona ama-homopolymer e-hydrogenated e-butadiene, aqedwa yiqembu le-hydroxyl futhi afanele ukusetshenziswa okubanzi. Ngenxa yokugcwala kweqembu le-1,2-vinyl lawa ma-polybutadiene anokuqina kwamakhemikhali kwesikhathi eside okuhle kakhulu.
Izakhiwo njenge:
Isakhiwo esiguquguqukayo kakhulu
Ukungathandi amanzi
I-dielectric constant ephansi
Ukumelana okuhle kwamakhemikhali
Amaqembu e-hydroxyl asebenzayo
Ukuqina kwesikhathi eside
Izilungisi ze-resin, ama-resin e-urethane (upende, izinamathiseli, ama-ejenti okumboza), izinto zokuvikela zikagesi, ama-elastomer e-TPU
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.
