Hal koox hydroxyl HTPB CAS 69102-90-5 Hydroxyl-la joojiyay polybutadiene HTPB oo leh hal silsilad oo hydroxyl -OH iyo nooca hydrogenated
HTPB / Hydroxyl-la joojiyay polybutadiene CAS: 69102-90-5
Faahfaahinta alaabta:
Magaca Kiimikada: Kooxda kaliya ee hydroxyl HTPB/Hydroxyl-la joojiyay polybutadiene
Koodhka: HTPB-OH
CAS: 69102-90-5
Formula:
Dabeecadda: Shiinuhu Shatiga dhoofinta Idman ee dhoofiyaha/HTPB

HTPB waa dareere polymer cidiyaha fog fog, caag dareere cusub. Guryuhu way kala duwan yihiin sababtoo ah HTPB waa isku dhafka halkii ay ka ahaan lahayd xarun saafi ah, waxaana loo soo saaray si loo buuxiyo shuruudaha gaarka ah ee macaamiisha. HTPB-ga caadiga ah waa R-45M iyadoo cidhif kasta oo silsiladda ah lagu joojiyo koox hydroxyl [OH]. (PS: waxaan samayn karnaa nooc kasta oo HTPB ah sida ay macaamiishu codsadaan, iyo naqshad cusub oo HTPB ah oo leh hal silsilad hydroxyl -OH, Dhanka kale, waxaan samayn karnaa hydrogenation of HTPB)
Kooxda kaliya ee hydroxyl HTPB waa shey polybutadiene ah oo leh kooxo hydroxyl ah hal daraf, taas oo ku guuleysan karta daaweyn labanlaab ah ee hydroxyl iyo kooxaha vinyl. Waxay leedahay reactivity sare, hydrophobicity aad u fiican iyo guryaha dielectric, iyo waxqabadka processing wanaagsan.
HTPB waxay leedahay diapaneity wanaagsan, viscosity hooseeya, caabbinta gabowga, waxqabadka heerkulka hooseeya, caabbinta Hydrolysis, caabbinta acid iyo alkali, xidhashada caabbinta iyo sifooyin koronto oo aad u fiican
iyo waxqabadka processing waa wanaagsan yahay. HTPB waxaa loo isticmaali karaa:
- Xabag
- Selents
- Polymers
- Qalabka dahaarka korontada
- Qalabka ilaalinta biyuhu iyo daxalka
- Dahaarka
- Qalabka polyurethane
- Alaabta caagga ah
- Shidaal adag
- Dhaqaale
- Baabuurka iyo diyaaraduhu taayirada qalabka dhismaha
-HTPB+AP+Al)
- Hawada sare, gantaalada iyo gantaalaha
- saliidaha saliidda
- iyo sidoo kale noocyo badan oo isticmaalka ah.
Baakad:
Waxaa lagu soo xidhay 50kg/durbaan, 170kg/durbaan, Muddada kaydinta waa 1 sano.
Tilmaamaha badbaadada:
Kaydinta waa inay ahaataa mid qabow, engegan oo hawo leh. Heerkulka ugu fiican waa -20-38 ° C. Nolosha shelf ee 12 bilood, haddii ay dhacdo, weli la isticmaalo haddii ilaa heerka caadiga ah dib loo tijaabiyo. Marka gaadiidku waa inuu ka fogaado roobka, iftiinka qorraxda. Ha ku darin oksidizer xooggan.
