Cov ntsiab lus khoom:
Lub Npe Tshuaj: Ib pawg hydroxyl HTPB / Hydroxyl-terminated polybutadiene
Code: HTPB-OH
CAS: 69102-90-5
Cov mis:
Tus cwj pwm: Tuam Tshoj Tso Cai Exporter / HTPB export daim ntawv tso cai

HTPB yog cov kua polymer uas ua los ntawm cov kua dej, cov roj hmab tshiab. Cov yam ntxwv sib txawv vim HTPB yog ib qho sib xyaw es tsis yog cov tshuaj dawb huv, thiab nws yog tsim los ua kom tau raws li cov neeg siv khoom xav tau tshwj xeeb. Ib qho HTPB feem ntau yog R-45M nrog txhua qhov kawg ntawm cov saw hlau xaus nrog pawg hydroxyl [OH]. (PS: peb tuaj yeem ua txhua yam versions ntawm HTPB raws li cov neeg siv khoom thov, thiab tsim tshiab HTPB nrog ib txoj saw ntawm hydroxyl -OH, Lub caij no, peb tuaj yeem ua hydrogenation ntawm HTPB)
Ib pawg hydroxyl HTPB yog ib yam khoom polybutadiene nrog cov pawg hydroxyl ntawm ib kawg, uas tuaj yeem ua tiav ob zaug kho ntawm cov pawg hydroxyl thiab vinyl. Nws muaj kev ua haujlwm siab, hydrophobicity zoo heev thiab dielectric zog, thiab kev ua haujlwm zoo.
HTPB muaj diaphaneity zoo, viscosity tsawg, laus tsis kam, kub tsis kam, Hydrolysis tsis kam, acid thiab alkali tsis kam, hnav tsis kam thiab hluav taws xob zoo heev rwb thaiv tsev.
thiab kev ua haujlwm zoo. HTPB siv tau rau hauv:
- Cov nplaum
- Cov tshuaj nplaum
- Cov khoom siv polymer
- Cov ntaub ntawv rwb thaiv tsev hluav taws xob
- Cov ntaub ntawv tiv thaiv dej thiab corrosion
- Txheej
- Cov ntaub ntawv polyurethane
- Cov khoom siv roj hmab
- Roj khoom khov
- Cov roj av
- Cov log tsheb thiab dav hlau ua los ntawm cov khoom siv hauv tsev
- Hydroxyl-terminated polybutadiene propellant (HTPB + AP + Al)
- Kev Siv Dav Hlau, Rockets thiab Missile
- cov roj lubricating
- thiab lwm yam ntawm ntau hom kev siv.
Ntim khoom:
Ntim rau hauv 50kg / nruas, 170kg / nruas, Lub sijhawm cia khoom yog 1 xyoos.
Cov lus qhia txog kev nyab xeeb:
Kev khaws cia yuav tsum tau khaws cia rau qhov chaw txias, qhuav thiab muaj cua nkag. Qhov kub zoo tshaj plaws yog -20 ~ 38 ℃. Lub sijhawm khaws cia yog 12 lub hlis, yog tias tas sij hawm, tseem siv tau yog tias ua tau raws li tus qauv los ntawm kev rov kuaj dua. Thaum thauj mus los yuav tsum tsis txhob los nag lossis tshav ntuj. Tsis txhob sib tov nrog cov tshuaj oxidizing muaj zog.
