CAS 69102-90-5 HTPB yakasimba propellant Hydroxyl-terminated polybutadiene HTPB ye propellant, adhesive, sealant
HTPB / Hydroxyl-terminated polybutadiene CAS: 69102-90-5
Ruzivo rwechigadzirwa:
Kemikari Zita: Hydroxyl-terminated polybutadiene
Kodhi: HTPB, HTPB-R45M
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 uye cheni yekuwedzera mumiririri, crosslinking mumiririri mukamuri tembiricha kana yakakwirira tembiricha kuita inogona kugadzira 3D network chimiro chekurapa zvirimo.Iyo inorapa yemukati ine yakanakisa michina zvimiro, kunyanya kwakanaka kupikisa hydrolysis, asidhi uye alkali inodzivirira, kusapfeka kupfeka, kushoma tembiricha kuramba uye. yakanakisa magetsi ekudzivirira.
Polyurethanes yakagadzirirwa kubva kuHTPB inogona kugadzirwa kune chaiyo yemuviri zvivakwa; polyurethanes inogona kunge yakanyungudika kana yakasimba uye yakasimba. Zvimwe zvigadzirwa zvinosanganisira: rigid foam insulation panels; mavhiri akasimba elastomeric uye matai (anoshandiswa kune roller coasters, escalators, skateboards, nezvimwewo); motokari kumisa bushings; magetsi potting compounds; adhesives epamusoro-soro; zvipfeko zvepamusoro uye zvisimbiso zvepamusoro; synthetic fibers (semuenzaniso, Spandex); carpet underlay; zvikamu zvepurasitiki zvakaoma (semuenzaniso, zvezviridzwa zvemagetsi).
Kushandiswa kwakakosha kweHTPB kuri mune yakasimba rocket propellant. Inosunga iyo oxidizing agent, mafuta uye zvimwe zvinongedzo kuita yakasimba asi elastic mass mune akawanda anoumba propellant masisitimu. Iyo yakarapwa polyurethane inoshanda sehuni mumasanganiswa akadaro. Semuenzaniso propellant se "HTPB/AP/Al=12/68/20", zvinoreva, zvakaenzana nehuwandu, HTPB pamwe nekurapa 12% (binder nemafuta), ammonium perchlorate 68% (oxidizer), uye aluminium poda 20% (mafuta).
Mapropellant akafanana, anowanzonzi APCP (ammonium perchlorate composite propellant) anoshandiswa mumaroketi makuru emhando. Iyo yakajairwa APCP inogadzira 2-3 nguva yakanangana neiyo dema poda propellant inoshandiswa mumazhinji madiki maroketi mota.
HTPB inoshandiswawo semafuta akasanganiswa roketi.
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
- 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.
