Rimwe boka rehydroxyl HTPB CAS 69102-90-5 Hydroxyl-terinated polybutadiene HTPB ine ketani imwe chete yehydroxyl -OH uye hydrogenated shanduro.
HTPB / Hydroxyl-terminated polybutadiene CAS: 69102-90-5
Ruzivo rwechigadzirwa:
Kemikari Zita: Imwechete hydroxyl boka HTPB / Hydroxyl-terinated polybutadiene
Kodhi: HTPB-OH
CAS: 69102-90-5
Formula:
Hunhu: China Authorized Exporter / HTPB rezinesi rekunze
Chiyero: GB (Civil Giredhi) / GJB (Giredhi reMauto/ GJB 1327A-2003)
HTPB imvura iri kure claw polymer, iyo nyowani yemvura rabha. Izvo zvivakwa zvinosiyana nekuti HTPB musanganiswa kwete musanganiswa wakachena, uye inogadzirwa kuti isangane nevatengi zvinodiwa. HTPB yakajairwa ndeye R-45M nekumagumo kwecheni inogumiswa neboka rehydroxyl [OH]. (PS: tinogona kuita chero shanduro dzeHTPB sekukumbira kwevatengi, uye dhizaini nyowani iyo HTPB ine ketani imwe chete yehydroxyl -OH, Zvichakadaro, tinogona kuita hydrogenation yeHTPB.)
Iyo imwechete hydroxyl boka HTPB chigadzirwa chepolybutadiene chine hydroxyl mapoka kune imwe mugumo, iyo inogona kuwana kaviri kurapwa kwehydroxyl uye vinyl mapoka. Iyo ine yakakwirira reactivity, yakanakisa hydrophobicity uye dielectric zvivakwa, uye yakanaka kugadzirisa kuita.
HTPB ine yakanaka diaphaneity, yakaderera viscosity, kuchembera kuramba, yakaderera tembiricha kuita, Hydrolysis resistance, asidhi uye alkali kuramba, kupfeka kuramba uye kunaka kwemagetsi ekudzivirira zvinhu.
uye kugadzirisa kushanda kwakanaka. HTPB inogona kushandiswa mu:
- Adhesive
- Sealents
- Polymers
- Magetsi ekudzivirira zvinhu
-Kudzivirira mvura uye ngura yekudzivirira zvinhu
- Coating
- Polyurethane zvinhu
- Rubber zvigadzirwa
- Mafuta akasimba
- Propellant
-Mota uye Mapuraneti matai ezvimiro zvezvinhu
- Hydroxyl-terminated polybutadiene propellant (HTPB+AP+Al)
- Aerospace, Rockets uye Missile
- mafuta ekuzora
- uye nezvimwe zvakawanda zvekushandisa.
Packing:
Yakarongedzwa mu50kg / drum, 170kg / drum, Nguva yekuchengetedza ndeye 1 gore.
Mirayiridzo yekuchengetedza:
Kuchengetera kunofanirwa kunge kuchitonhorera, kuoma uye kufefetera. Mamiriro akanaka ari pakati -20 ~ 38 ℃. Sherufu yemwedzi gumi nemiviri, kana yapera, ichiri kushandiswa kana yasvika pachiyero kuburikidza nekuongororazve. Apo kutakurwa kunofanira kudzivisa mvura, chiedza chezuva. Usasanganise neoxidizer yakasimba.
