IHydrogenated HTPB Hydrogenated Hydroxyl Group-Inqanyuliwe I-Polybutadiene Isithombe Esifakiwe

I-HTPB Ye-Hydrogenated Hydroxyl Group-Inqanyuliwe I-Polybutadiene

Incazelo emfushane:

I-HTTPB 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 idizayini entsha njenge-HTPB nge-OH eyodwa ngeketango ngalinye kanye nenguqulo ye-Hydrogenated).

Izici

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)

Ngoba i-HTPB ene-Hydrogenated i-hydrogenated homopolymers ye-butadiene, ayi-hydroxyl yokuphela kweqembu eqediwe futhi ifanele ukusetshenziswa okubanzi. Ngenxa yokugcwala kweqembu le-1,2-vinyl lawa ma-polybutadienes anokuqina okuhle kakhulu kwamakhemikhali kwesikhathi eside.

Izakhiwo njenge:

Isakhiwo esivumelana nezimo kakhulu

I-Hydrophobia

I-dielectric engaguquki ephansi

Ukumelana okuhle kwamakhemikhali

Amaqembu e-hydroxyl asebenzayo

Ukuzinza kwesikhathi eside

Izinhlelo zokusebenza

Ama-resin modifiers, ama-urethane resins(amapende, izinto zokunamathisela, izinto zokunamathisela), izinto zokuvikela ugesi, ama-TPU elastomers

Ukupakisha & Isitoreji

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.
