Hal koox oo hydroxyl ah HTPB CAS 69102-90-5 Polybutadiene-ka la joojiyay ee Hydroxyl HTPB oo leh silsilad keliya oo hydroxyl -OH ah iyo nooc hydrogenated ah
Polybutadiene-ka HTPB / Hydroxyl-joojiyay CAS: 69102-90-5
Faahfaahinta alaabta:
Magaca Kiimikada: Hal koox oo hydroxyl ah oo HTPB / Polybutadiene ah oo la joojiyay Hydroxyl
Koodhka: HTPB-OH
CAS: 69102-90-5
Qaacidada:
Jilaha: Dhoofiye La Oggolaaday / Shatiga Dhoofinta HTPB ee Shiinaha

HTPB waa polymer-ka fog ee cidiyaha dareeraha ah, oo ah caagga dareeraha ah ee cusub. Sifooyinku way kala duwan yihiin sababtoo ah HTPB waa isku-darka halkii laga isticmaali lahaa isku-darka saafiga ah, waxaana loo sameeyay si loo daboolo shuruudaha gaarka ah ee macaamiisha. HTPB-ga caadiga ah waa R-45M iyadoo dhammaad kasta oo silsiladda ah lagu dhammeeyo koox hydroxyl [OH].PS: waxaan samayn karnaa nooc kasta oo HTPB ah sida macaamiishu codsadaan, iyo naqshad cusub oo HTPB ah oo leh hal silsilad oo hydroxyl -OH ah, Dhanka kale, waxaan samayn karnaa hydrogenation-ka HTPB)
Kooxda hydroxyl ee keliya ee HTPB waa badeecad polybutadiene ah oo leh kooxo hydroxyl ah dhinac, kuwaas oo gaari kara bogsiin labanlaab ah oo kooxaha hydroxyl iyo vinyl ah. Waxay leedahay falcelin sare, sifooyin hydrophobic iyo dielectric ah oo aad u fiican, iyo waxqabad farsamayn oo wanaagsan.
HTPB waxay leedahay diaphaneity wanaagsan, viscosity hooseeya, iska caabin gabowga, waxqabadka heerkulka hooseeya, iska caabinta hydrolysis, iska caabinta aashitada iyo alkali, iska caabin xirasho iyo sifooyin dahaarka korantada oo aad u fiican.
waxqabadka farsamayntuna waa wanaagsan yahay. HTPB waxaa loo isticmaali karaa:
- Koollo
- Shaabadaha
- Polymers
- Qalabka dahaarka korontada
- Qalabka ka hortagga biyaha iyo daxalka
- Dahaarka
- Qalabka Polyurethane
- Alaabada caagga ah
- Shidaal adag
- Dareeraha
- Taayirada Baabuurta iyo Diyaaradaha ee agabka dhismaha
- Qalabka polybutadiene ee la joojiyay ee hydroxyl (HTPB+AP+Al)
- Hawada Sare, Gantaalada iyo Gantaalada
- saliidaha saliidda
- iyo noocyo badan oo isticmaalka ah.
Baakad:
Waxaa lagu soo buuxiyay 50kg/durbaan, 170kg/durbaan, Muddada kaydinta waa 1 sano.
Tilmaamaha badbaadada:
Kaydintu waa inay ahaataa mid qabow, qalalan oo hawo leh. Xaaladda ugu fiican waa -20 ~ 38℃. Muddada kaydinta waa 12 bilood, haddii ay dhacdo, wali waa la isticmaalaa haddii ay heer caadi ah gaarto iyada oo dib loo tijaabinayo. Marka gaadiidku uu roobka ka fogaado, iftiinka qorraxda. Ha ku qasin oksaydheeye xooggan.
