Hydrogenated HTPB Hydrogenated Hydroxyl Group-Terminated Polybutadiene

Tsananguro pfupi:

HTTPB ipolymer yemvura iri kure neclaw, rabha itsva yemvura. Hunhu hwayo hunosiyana nekuti HTPB musanganiswa kwete musanganiswa wakachena, uye inogadzirwa kuti ienderane nezvinodiwa nevatengi. HTPB yakajairika iR-45M ine magumo ese echeni inogumiswa neboka rehydroxyl [OH]. (PS: tinogona kugadzira dhizaini nyowani seHTPB ine -OH imwe chete pacheni uye Hydrogenated version).

Yakasanganiswa nehydrogenated HTTPB Hydrogenated Hydroxyl Group-Yakagumiswa Polybutadiene

Ruzivo rwechigadzirwa:

Zita reKemikari: Hydrogenated HTPB

Rudzi: Shanduro yeHydrogenated

Fomura:

Hunhu: Chitupa chekutumira kunze chine mvumo chekuChina / rezinesi rekutumira kunze reHTPB

Zvinhu zvirimo

HTPB ipolymer yemvura iri kure neclaw, rabha itsva yemvura. Hunhu hwayo hunosiyana nekuti HTPB musanganiswa kwete chinhu chakachena, uye inogadzirwa kuti ienderane nezvinodiwa nevatengi. HTPB yakajairika iR-45M ine magumo ese echeni anogumiswa neboka rehydroxyl [OH].PS: tinogona kuita chero shanduro dzeHTPB sekukumbira kwevatengi, uye kugadzira HTPB itsva necheni imwe chete yehydroxyl -OH, Panguva iyi, tinogona kuita hydrogenation yeHTPB)

Kune Hydrogenated HTPB ine hydrogenated homopolymers yebutadiene, inogumiswa ne hydroxyl group uye yakakodzera kushandiswa kwakasiyana-siyana. Nekuda kwekuzara kwe1,2-vinyl group, ma polybutadiene aya ane kugadzikana kwakanaka kwenguva refu kwemakemikari.

Kurongedza & Kuchengeta

Kurongedza:

Yakaputirwa mu50kg/dhiramu, 170kg/dhiramu, Nguva yekuchengetera igore rimwe chete.

Mirayiridzo yekuchengetedza:

Kuchengetera kunofanira kunge kuri panzvimbo inotonhorera, yakaoma uye inofefetedza mweya. Mamiriro akanaka ari pakati pe -20 ~ 38℃. Nguva yekuzorora ndeyemwedzi gumi nemiviri, kana yapera, ichiri kushandiswa kana yasvika padanho repamusoro kuburikidza nekuyedzazve. Kana kutakurwa kunofanirwa kudzivirira mvura, chiedza chezuva. Usasanganisa neoxidizer yakasimba.
